Flip the boolean state of the primary verb (e.g., \"promotes\"\n    becomes \"does not promote\").\n\n3. ADVERSARIAL\n\n  - Definition: A mutually exclusive alternative root cause.\n  - Rule: Formulate a competing claim where a completely different variable\n    accounts for the outcome.\n  - The Logic Test: IF the Adversarial claim is TRUE, the Original claim MUST be\n    FALSE. It must represent a conflict of causality.\n\n4. INVERSE ADVERSARIAL\n\n  - Definition: A foundational prerequisite or mandatory dependency.\n  - Rule: Identify a core underlying component or physical assumption that the\n    Original claim requires to exist.\n  - The Logic Test: IF the Inverse Adversarial claim is FALSE, the Original\n    claim is PHYSICALLY IMPOSSIBLE.\n\nOUTPUT FORMAT\n\nReturn ONLY valid JSON.

NT-a9 is a novel triazole antifungal with potent activity against Candida and Cryptococcus species via strong inhibition of ergosterol biosynthesis. In vitro, NT-a9 exhibited potent and sustained antifungal activity against clinical isolates, with superior potency compared to fluconazole (FLC). It also displayed a prolonged post-antifungal effect (PAFE) against most Candida species, a property rarely seen in conventional azoles. Resistance profiling demonstrated that NT-a9 possesses a high genetic barrier, fully suppressing resistant mutant emergence in Cryptococcus species and maintaining stable susceptibility in Candida albicans during 28 days of continuous exposure. NT-a9 retained potent activity against FLC-resistant Cryptococcus neoformans and multidrug-resistant Candida auris, with minimal influence from drug efflux mechanisms. In murine invasive candidiasis, a single low dose of NT-a9 achieved 100% survival and markedly reduced renal fungal burden, significantly outperforming FLC. NT-a9 also substantially improved survival in mice infected with FLC-resistant C. auris. Mechanistically, NT-a9 binds Erg11 with much higher affinity than FLC by forming key hydrogen bonds with Gly307 and His377, leading to irreversible ergosterol depletion, toxic sterol accumulation, and severe fungal membrane damage. Transcriptomic analysis further confirmed that NT-a9 extensively disrupts sterol biosynthesis and triggers compensatory gene expression that reinforces its antifungal action. As a novel triazole integrating long-lasting efficacy, a high resistance barrier, and potent activity against pan-azole-resistant pathogens, NT-a9 represents a promising clinical candidate for treating IFIs."

Here, we investigated whether laboratory exposure of a clade III clinical C. auris isolate to TCZ could induce cross-resistance to clinical antifungals. Among 17 agrochemicals tested, only TCZ exhibited intrinsic antifungal activity. Brief (48 h) exposure to sub-MIC TCZ (1 \u03bcg/mL) selected variants (6.9% frequency) with cross-resistance to TCZ and fluconazole, but full susceptibility to caspofungin. Exposure to supra-MIC TCZ (8-32 \u03bcg/mL) produced three phenotypic classes: Class 2 (TCZ-R, fluconazole-R) and Class 3 (TCZ-R, fluconazole-R, plus tolerance to caspofungin and micafungin). The frequency of Class 3 increased dose-dependently from 23% to 50% as TCZ concentration rose. RNA-Seq revealed that both classes overexpressed MDR1, TAC1b, UPC2 and FKS1, but Class 2 showed broad ergosterol pathway upregulation, whereas Class 3 exhibited restricted ergosterol activation but downregulation of the sole chitinase gene CHT1 (5.17-fold), a known mechanism of echinocandin tolerance. Unlike the CRS-MIS phenomenon in Candida glabrata, our Class 3 adaptors displayed equal tolerance to both caspofungin and micafungin. Collectively, these findings demonstrate that, in a clade III clinical isolate of C. auris under the tested laboratory conditions, laboratory exposure to an agricultural triazole can rapidly select for clinically relevant azole cross-resistance and echinocandin tolerance in C. auris, suggesting that environmental fungicide use may inadvertently compromise the efficacy of last-line antifungals."

Pronounced drug resistance makes treatment failure common, and so does antifungal tolerance, a phenomenon enabling pathogen survival at supra-MIC concentrations without resistance mutations. Here, we uncover a mechanism of antifungal tolerance in C. auris engaging the mitochondrial cytochrome bc1 complex. Deletion of RIP1, a conserved catalytic complex subunit, does not significantly alter the susceptibility to caspofungin or voriconazole. However, rip1\u0394 mutants exhibit a marked reduction in antifungal tolerance across a wide range of supra-MIC concentrations.

Targeting cytochrome bc1 function with the fungal-specific inhibitor Inz-5 enhances antifungal action of both voriconazole and caspofungin. Additionally, ablation of RIP1 causes fitness defects, suggesting that cytochrome bc1 is a potential antifungal target against C. auris infections."

In this study, we report the synthesis, characterization, and biological evaluation of a guar gum-quercetin bioconjugate designed to improve the practical applicability of quercetin through covalent conjugation with a biocompatible polysaccharide scaffold and a cystamine-based disulfide linker. The formation of the GG-Cys-Quer conjugate was supported by FTIR, 1H/13C NMR, CHNS elemental analysis, degree-of-substitution estimation, SEM, and TGA. The conjugate showed potent antifungal activity against five clinical C. auris isolates, with MIC and MFC values ranging from 0.030 to 0.245 \u00b5g mL-1 and 0.123 to 0.488 \u00b5g mL-1, respectively. Against the resistant isolate MRL6057, GG-Cys-Quer showed an MIC of 0.245 \u00b5g mL-1, whereas caspofungin showed an MIC of 4.0 \u00b5g mL-1 under the same assay conditions.

In this study, three clinical C. auris strains (namely C. auris strain 01, C. auris strain 03, and C. auris strain 13) with distinct origins were characterized to investigate their phenotypic variations and mechanisms of azole resistance. Comprehensive profiling revealed significant inter-strain differences in biofilm formation, cell surface hydrophobicity, adhesion capacity, and phospholipase activity. Testing for antifungal susceptibility showed that the three clinical strains exhibited different minimum inhibitory concentrations for multiple azoles (fluconazole, voriconazole, and itraconazole) and echinocandins (anidulafungin and micafungin). Sequencing identified Y132F mutations in the ERG11 gene of the three clinical strains. Mechanistic investigations demonstrated that fluconazole exposure significantly upregulated the expression of efflux pump genes (CDR1 and CDR2) and the genes encoding their transcriptional regulators (MDR1 and TAC1b). In a murine skin colonization model, comparing data from the standard strain C. auris strain CBS12766 and clinical strains of C. auris strain 03 and C. auris strain 13 exhibited a significantly higher fungal burden of tissue, whereas strain C. auris strain 01 showed an intermediate level. Host immunity response analysis revealed that expression of the IL-1\u03b2 gene was significantly elevated in C. auris strain CBS12766-infected mice, while expression of IL-6 and CXCL-1 genes was predominantly increased in the C. auris strain 01, with TNF-\u03b1 gene expression levels being comparable across all strains. Histopathological examination confirmed local infiltration of inflammatory cells and mild epidermal edema, indicating active host immune engagement. Overall, our findings highlighted substantial phenotypic heterogeneity, different colonization capacities, and differences in expression of inflammatory cytokines among the C. auris strains.

While point mutations underlying antifungal resistance are well characterised, the contribution of structural genomic variation to antifungal responses remains poorly defined. Here, we integrate whole-genome sequencing, a genome-wide copy number variation (CNV) screen, electrophoretic karyotyping, and mutation-accumulation analyses to investigate the role of structural variation in antifungal susceptibility across a clinical cohort of C. auris isolates. We identify recurrent CNV hotspots, with segmental duplications representing a predominant mode of genome variation. Small duplications encompassing ERG11 arise at high frequency and frequently co-occur with drug resistance-associated ERG11 mutations, collectively enhancing azole resistance. In addition, large centromere-inclusive duplications of chromosome 1 generate supernumerary chromosomes, leading to paradoxical growth and reduced susceptibility to caspofungin, an echinocandin. At the population level, structural variants frequently arise in parallel to FKS1 mutations, suggesting multiple genetic mechanisms underlying reduced drug susceptibility. Together, our findings establish segmental duplication as a major, non-mutational driver of antifungal resistance, highlighting the need to consider structural genomic variation in both resistance surveillance and clinical susceptibility testing."

Human immunity to C. albicans infection is thought to be largely dependent on neutrophil reactive oxygen and nitrogen species (ROS/RNS) generation by neutrophils. Despite this, our understanding of innate immune killing and escape by C. albicans is primarily studied in macrophages, and the precise mechanisms of evasion are unclear in neutrophils. Here, we sought to determine the importance of neutrophil reactive nitrogen species (RNS) production during C. albicans infection in vivo. Using a zebrafish model, we found that C. albicans rapidly downregulated neutrophil RNS below basal levels during the first day post-infection, a time at which neutrophil RNS is upregulated in bacterial infections as an important host-defense mechanism, indicating fungal evasion of host neutrophils. We confirmed the downregulation of RNS in human primary neutrophils and with clinical Candida isolates, including emerging human pathogens Candida auris and Candida glabrata. Inducible nitric oxide synthase (iNOS; Nos2 in zebrafish), the enzyme responsible for RNS production, competes with the arginase enzyme for a shared substrate, L-arginine. Using a zebrafish arginase2 transgenic line and a C. albicans car1\u0394 mutant, we showed that both host and fungal arginase contribute to the reduction in neutrophil RNS. Despite pathogen downregulation, upregulation of neutrophil RNS via hypoxia-inducible factor 1\u03b1 (Hif-1\u03b1) stabilization was sufficient to improve host survival following C. albicans infection. Inhibition of Nos2 blocked the host protective effect of Hif-1\u03b1 stabilization. Finally, restoration of neutrophil RNS via Hif-1\u03b1 stabilization was additive to clinically relevant antifungal treatment, increasing survival and clearance of C. albicans infections. Together, these data demonstrate that restoration of the neutrophil RNS response in C. albicans infection improves infection outcomes, highlighting the potential of targeting Hif-1\u03b1 and RNS in host-directed therapies against fungal infections.IMPORTANCECandida albicans is a fungus that normally lives harmlessly in the human body but can cause life-threatening infections in people with weakened immune systems. A key part of the body's defense against this fungus is neutrophils, immune cells that kill microbes using toxic molecules. However, how Candida avoids neutrophil defense is not well understood. Here, we used zebrafish and human immune cells to show that Candida suppresses an important neutrophil defense, reactive nitrogen species (RNS), during infection. Unlike bacteria, which trigger RNS, Candida reduces these protective molecules to below normal levels, helping its survival. This effect was also observed with other disease-causing Candida species. We went on to show that both the host and Candida contribute to this suppression. Importantly, boosting the neutrophil response improved survival and helped clear infection, especially when combined with standard antifungal drugs. These findings suggest new ways to support the immune system alongside existing treatments."

In this study, we demonstrated that the Neosartorya (Aspergillus) fischeri antifungal protein NFAP2 selectively targets early morphogenetic states of Candida albicans and Candidozyma auris, revealing a transient window of susceptibility during filament and pseudohypha formation. Integrated transcriptomic and in vivo analyses indicate that these developmental states may represent context-dependent entry points for NFAP2 activity. In C. albicans, transcriptomic and network analyses indicate the presence of an anabolic, translation-associated gene expression signature, accompanied by suppression of stress-protective pathways, which is associated with increased susceptibility of emerging hyphae to NFAP2 but does not establish a direct causal mechanism. In C. auris, increased susceptibility of pseudohyphal cells occurred without overt transcriptional remodeling, consistent with the characteristically muted gene expression responses of this species, suggesting that NFAP2 sensitivity is governed primarily by biophysical and post-transcriptional mechanisms rather than transcriptional reprogramming. Importantly, morphotype-specific vulnerabilities observed in vitro were reflected in distinct in vivo outcomes in Galleria mellonella, as NFAP2 was well tolerated and provided a moderate, transient survival benefit in pseudohyphal C. auris infections, but not in filamentous C. albicans, where a worsened outcome was observed, consistent with species- and morphotype-dependent activity. Taken together, these results suggest that early morphogenetic states of Candida are stress-sensitive phenotypes associated with increased susceptibility to NFAP2. This work provides a proof-of-concept framework for future investigation of morphotype-associated antifungal vulnerability to peptide-based antifungal strategies.IMPORTANCEDrug-resistant Candida species represent an escalating global health threat; however, most antifungal strategies continue to target fungal growth rather than intrinsic biological vulnerabilities. In this study, we identified early morphogenetic transitions as a shared window of increased susceptibility in both Candida albicans and the highly drug-resistant pathogen Candidozyma (formerly Candida) auris. By integrating transcriptomic profiling with in vivo infection models, we found that NFAP2 exhibits antifungal activity that is influenced by these transient developmental states in a context-dependent manner while remaining well tolerated by the host. We further demonstrated that morphotype-specific stress responses are associated with the divergent sensitivities of C. albicans and C. auris to NFAP2. These results support the concept that fungal morphogenesis may represent a therapeutically actionable process and provide a framework for designing antifungal strategies that target developmental states rather than growth. This strategy may open new opportunities for improving protein- and peptide-based therapies, as well as combination therapies against difficult-to-treat fungal pathogens."

However, the molecular mechanisms underlying its virulence remain incompletely understood. In this study, we performed in vivo transcriptome analysis using an immunosuppressed mouse gastrointestinal infection model to identify genes associated with host adaptation and virulence during infection. By comparing fungal transcriptomes obtained from colonization and dissemination sites with those from\u00a0in vitro cultures, we identified genes that were consistently upregulated during infection. Among these genes, the unfolded protein response regulator HAC1 was selected as a candidate virulence-associated gene for further analysis. Reverse transcription PCR and sequencing analyses revealed that\u00a0HAC1 mRNA in C. auris undergoes an unconventional splicing event of 287 bp that is enhanced under endoplasmic reticulum stress conditions. The excised region spans the annotated open reading frame boundary, suggesting that the translated region of\u00a0HAC1 may require re-evaluation. Notably, a proportion of HAC1 transcripts appeared to be spliced even under non-stress conditions, indicating a detectable basal level of the unfolded protein response. Differences in splicing dynamics were also observed among clade strains. Functional analyses demonstrated that deletion of\u00a0HAC1 increased sensitivity to endoplasmic reticulum stress. The HAC1 deletion mutant also exhibited reduced virulence in both Galleria mellonella and immunosuppressed mouse infection models, as evidenced by delayed host mortality and decreased fungal burdens, respectively. These findings indicate that HAC1 contributes to endoplasmic reticulum stress adaptation and survival in the host environment and identify\u00a0HAC1 as a virulence-associated gene in C. auris. Candida auris is an emerging multidrug-resistant fungal pathogen.

In this study, we employed a targeted drug-repurposing strategy to identify novel indications for existing FDA-approved compounds against C. auris, leading to the identification of Tavaborole as a potent fungistatic agent. Tavaborole displayed robust activity across all five tested clades of C. auris, as well as against Candida albicans and Candida glabrata.

Proteomic profiling revealed that C. auris mounts distinct but overlapping adaptive responses to antifungal stress, involving stress response pathways, metabolic reprogramming and amino acid biosynthesis. While Tavaborole primarily induced targeted stress adaptation, AmB triggered a broader, multi-pronged resistance response including oxidative stress mitigation, osmolyte production and metabolic remodeling.

Its high environmental persistence, immune evasion, phenotypic heterogeneity, and multidrug resistance are major contributors to its high mortality rate. Under diverse environmental conditions, C. auris exhibits marked phenotypic plasticity, switching from non-aggregative to aggregative form and, in some contexts, pseudohyphal-like morphotypes. However, the significance of this heterogeneity in pathogenesis and drug tolerance remains poorly understood. This review provides a comprehensive overview of how external cues influence C. auris morphotypes, with particular emphasis on aggregation. It further highlights the role of adhesion-associated genes (ALS4112 and SCF1) in mediating cell aggregation and examines their evolutionary trajectories across Candida species and among distinct C. auris clades. In addition, we discuss emerging molecular mechanisms that may underlie differential morphotypes and their links to virulence and antifungal tolerance. Evidence suggests that mannan-mediated masking of pathogen-associated molecular patterns (PAMPs) in the aggregative phenotype may contribute to persistence and reduced virulence in the host. Overall, C. auris can remodel its cell wall and elicit distinct host immune responses based on its form, opening avenues for novel therapeutic strategies which further require deeper experimental validation."

Notably, compound 9 exhibited potent antifungal activity against drug-resistant Candida auris 12766, with a MIC of 4\u202f\u03bcg/mL. In addition, compound 9 exhibited low hemolytic toxicity. The antifungal mechanism of compound 9 involves cell membrane disruption and intracellular ROS accumulation. In addition to these effects, it also inhibited biofilm formation in C. auris 12766. These findings highlight compound 9 as a promising antifungal candidate for treating C. auris."

We show that glucose starvation induced by major fungal pathogens Candida albicans and Candida auris causes macrophage lysis by activating NINJ1, the executioner of membrane rupture during cell death. In glucose-starved macrophages, NINJ1 ruptures membranes independently of known cell death programs. Consistently, NINJ1 is the dominant effector of fungal-induced macrophage damage amongst host cell death factors. Supplementation of the amino acid alanine rescues glucose-starved macrophages better than glucose, and it does so by inhibiting NINJ1 oligomerization. Moreover, C. albicans infection disrupts amino acid metabolism in mice and reduces serum alanine. Finally, NINJ1-mediated membrane rupture enables C. albicans egress from macrophages together with the toxin candidalysin. We establish the mechanism of glucose starvation-induced macrophage damage by NINJ1, and demonstrate the roles of NINJ1 and alanine in immune responses to Candida and fungal escape."

Its rapid global expansion and resistance to multiple antifungal classes pose major challenges to treatment and containment. Extracellular vesicles (EVs) have recently been recognized as important mediators of fungal communication, virulence, and stress adaptation. Here, we examine how caspofungin, a frontline echinocandin, reshapes the EV metabolome of C. auris. Caspofungin exposure drives pronounced remodeling of EV size distributions, yielding a predominance of smaller, more uniform EVs alongside a minor population of larger subtypes. Metabolomic profiling of EVs revealed marked enrichment of metabolites involved in nucleotide salvage and recycling, along with altered amino acid abundances, including increases in amino acids associated with stress responses and redox regulation. These changes are consistent with altered nucleotide turnover and amino acid metabolism under antifungal stress. Importantly, these metabolic alterations reflect caspofungin-induced changes in cellular metabolism that are selectively exported via extracellular vesicles, rather than metabolic activity occurring within the vesicles themselves. Export of these metabolites via EVs may support population-level coordination, biofilm remodeling, and modulation of host immune responses, contributing to echinocandin tolerance. Together, our findings highlight nucleotide- and amino acid-associated metabolic features of EVs as informative readouts of caspofungin exposure and highlight the EV metabolome as a promising source of non-invasive biomarkers for monitoring drug exposure and resistance. This work advances understanding of C. auris adaptation under antifungal stress and reveals new opportunities for therapeutic and diagnostic innovation against this high-priority pathogen."

However, accumulating evidence indicates that impaired drug import may also significantly contribute to reduced antifungal susceptibility. Sugar importers, historically viewed solely as hexose transporters (HGTs), are now emerging as potential indirect modulators of antifungal uptake. Here, we performed a comprehensive inventory and functional analysis of the HGT family in C. auris to assess its contribution to antifungal import. Phylogenetic analyses revealed that C. auris HGTs are more closely related to those of Candida albicans (C. albicans) than Saccharomyces cerevisiae (S. cerevisiae). All HGT genes showed basal expression, with several significantly downregulated upon fluconazole (FLC) exposure. To establish functional relevance, we generated a mini-library of HGT deletion mutants. Notably, the \u0394hgt13 strain exhibited markedly increased FLC resistance, concomitant with reduced intracellular FLC accumulation and decreased membrane permeability. Consistently, molecular docking and molecular dynamics simulations demonstrated strong and stable interactions between FLC and Hgt13p. Together, these findings implicate Hgt13p as a key determinant of FLC import and membrane permeability, revealing reduced FLC import could also contribute to antifungal resistance in C. auris."

Despite the recent emergence of at least four distinct clades at the global scale, little remains known about how C. auris is so adept at growing on skin and the key genes and pathways it utilizes to metabolize the scarce nutrients available. Here, we identify the roles that conventional and alternative carbon metabolism genes and metabolic pathways have in facilitating C. auris growth through laboratory-based experiments and bioinformatics analyses. In artificial skin-like media, all four clades of C. auris were more capable of growing than Candida albicans SC5314, a clinically relevant counterpart. By investigating the differential regulation of C. auris when growing in skin-like media as compared to rich fungal media, we uncovered hundreds of genes in multiple metabolic pathways. To further test the mechanisms of these metabolic pathways, we deleted several non-essential gene candidates including FOX2 (B9J08_002847), CAT2 (B9J08_000010), and ICL1 (B9J08_003374). The mutant strains all exhibited abrogated growth in skin-like media and demonstrated nutrient preferences that differed from the wild type. Thus, we propose a model of how C. auris has the capacity to metabolize nutrients that are available on skin by optimizing its metabolic profile. Targeting these metabolic pathways to mitigate C. auris growth on skin is a potential avenue to explore in controlling the spread of this emerging human fungal pathogen. Candida auris is an emerging fungal pathogen with human skin as its primary site of colonization and subsequent transmission. Here, we show the importance of conventional and alternative carbon metabolism for the ability of C. auris to grow in artificial skin-like media. This knowledge provides a better understanding of C. auris metabolism and sheds light on genes and pathways that could be targeted to interfere with persistent skin colonization."

NT-a9 is a novel triazole antifungal with potent activity against Candida and Cryptococcus species via strong inhibition of ergosterol biosynthesis. In vitro, NT-a9 exhibited potent and sustained antifungal activity against clinical isolates, with superior potency compared to fluconazole (FLC). It also displayed a prolonged post-antifungal effect (PAFE) against most Candida species, a property rarely seen in conventional azoles. Resistance profiling demonstrated that NT-a9 possesses a high genetic barrier, fully suppressing resistant mutant emergence in Cryptococcus species and maintaining stable susceptibility in Candida albicans during 28 days of continuous exposure. NT-a9 retained potent activity against FLC-resistant Cryptococcus neoformans and multidrug-resistant Candida auris, with minimal influence from drug efflux mechanisms. In murine invasive candidiasis, a single low dose of NT-a9 achieved 100% survival and markedly reduced renal fungal burden, significantly outperforming FLC. NT-a9 also substantially improved survival in mice infected with FLC-resistant C. auris. Mechanistically, NT-a9 binds Erg11 with much higher affinity than FLC by forming key hydrogen bonds with Gly307 and His377, leading to irreversible ergosterol depletion, toxic sterol accumulation, and severe fungal membrane damage. Transcriptomic analysis further confirmed that NT-a9 extensively disrupts sterol biosynthesis and triggers compensatory gene expression that reinforces its antifungal action. As a novel triazole integrating long-lasting efficacy, a high resistance barrier, and potent activity against pan-azole-resistant pathogens, NT-a9 represents a promising clinical candidate for treating IFIs."

In this study, we determined the antifungal activity of BE against multiple C. auris isolates, assessed its effects on fungal growth, virulence attributes, adhesion, and biofilm development, validated its in vivo protective efficacy in a Galleria mellonella infection model, and explored the underlying mechanisms via transcriptomic sequencing. BE exerted potent and consistent antifungal activity against all tested strains, with a minimum inhibitory concentration of 1 \u03bcg/mL, minimum fungicidal concentrations of 4-8 \u03bcg/mL, and a sessile minimum inhibitory concentration of 32 \u03bcg/mL.

Here, we investigated whether laboratory exposure of a clade III clinical C. auris isolate to TCZ could induce cross-resistance to clinical antifungals. Among 17 agrochemicals tested, only TCZ exhibited intrinsic antifungal activity. Brief (48 h) exposure to sub-MIC TCZ (1 \u03bcg/mL) selected variants (6.9% frequency) with cross-resistance to TCZ and fluconazole, but full susceptibility to caspofungin.

Novel antifungal agents and combination therapies offer potential options against resistant and biofilm-forming C. auris, while recent studies of aggregation, biofilm formation and adhesion, and phenotypic switching have provided new insights into its virulence and persistence in healthcare settings. C. auris exhibits many virulence traits that influence the severity of its infections.

In this study, three clinical C. auris strains (namely C. auris strain 01, C. auris strain 03, and C. auris strain 13) with distinct origins were characterized to investigate their phenotypic variations and mechanisms of azole resistance. Comprehensive profiling revealed significant inter-strain differences in biofilm formation, cell surface hydrophobicity, adhesion capacity, and phospholipase activity. Testing for antifungal susceptibility showed that the three clinical strains exhibited different minimum inhibitory concentrations for multiple azoles (fluconazole, voriconazole, and itraconazole) and echinocandins (anidulafungin and micafungin). Sequencing identified Y132F mutations in the ERG11 gene of the three clinical strains. Mechanistic investigations demonstrated that fluconazole exposure significantly upregulated the expression of efflux pump genes (CDR1 and CDR2) and the genes encoding their transcriptional regulators (MDR1 and TAC1b). In a murine skin colonization model, comparing data from the standard strain C. auris strain CBS12766 and clinical strains of C. auris strain 03 and C. auris strain 13 exhibited a significantly higher fungal burden of tissue, whereas strain C. auris strain 01 showed an intermediate level. Host immunity response analysis revealed that expression of the IL-1\u03b2 gene was significantly elevated in C. auris strain CBS12766-infected mice, while expression of IL-6 and CXCL-1 genes was predominantly increased in the C. auris strain 01, with TNF-\u03b1 gene expression levels being comparable across all strains. Histopathological examination confirmed local infiltration of inflammatory cells and mild epidermal edema, indicating active host immune engagement. Overall, our findings highlighted substantial phenotypic heterogeneity, different colonization capacities, and differences in expression of inflammatory cytokines among the C. auris strains.

Analysis of 80 peer-reviewed studies reveals five principal findings: (1) C. auris exhibits clade-dependent geographic distribution and resistance profiles-Clade I (South Asia) and Clade III show fluconazole resistance exceeding 90%, whereas Clade IV exhibits 44% resistance; echinocandin resistance varies significantly by clade and no resistance was detected in certain clades; amphotericin B resistance varies from no detected resistance to 46% depending on clade; and pan-resistant strains have emerged; (2) biofilm-associated C. auris cells (sessile cells) exhibit MBECs 2- to 4,119-fold higher than planktonic MICs, representing a major driver of persistent colonization; (3) novel antifungal agents, including ibrexafungerp, manogepix (the active moiety of fosmanogepix), and rezafungin, demonstrate promising in vitro activity against C. auris, with manogepix showing the highest overall antibiofilm activity (geometric mean MBEC of 5.9 \u03bcg/mL) and ibrexafungerp demonstrating superior activity against Clade IV biofilms; (4) a tiered infection prevention and control (IPC) framework-integrating universal screening, contact precautions, and environmental decontamination-has been associated with reduced transmission rates in outbreak settings; and (5) climate change and global warming may have contributed to the emergence of C. auris through thermal adaptation of environmental fungal species. These findings indicate that effective mitigation of the C. auris threat requires integrated surveillance, susceptibility-guided therapy accounting for both planktonic and biofilm activity, and resilient healthcare systems adapted to the clade-specific epidemiology of this pathogen."

While point mutations underlying antifungal resistance are well characterised, the contribution of structural genomic variation to antifungal responses remains poorly defined. Here, we integrate whole-genome sequencing, a genome-wide copy number variation (CNV) screen, electrophoretic karyotyping, and mutation-accumulation analyses to investigate the role of structural variation in antifungal susceptibility across a clinical cohort of C. auris isolates. We identify recurrent CNV hotspots, with segmental duplications representing a predominant mode of genome variation. Small duplications encompassing ERG11 arise at high frequency and frequently co-occur with drug resistance-associated ERG11 mutations, collectively enhancing azole resistance. In addition, large centromere-inclusive duplications of chromosome 1 generate supernumerary chromosomes, leading to paradoxical growth and reduced susceptibility to caspofungin, an echinocandin. At the population level, structural variants frequently arise in parallel to FKS1 mutations, suggesting multiple genetic mechanisms underlying reduced drug susceptibility. Together, our findings establish segmental duplication as a major, non-mutational driver of antifungal resistance, highlighting the need to consider structural genomic variation in both resistance surveillance and clinical susceptibility testing."

In this study, we demonstrated that the Neosartorya (Aspergillus) fischeri antifungal protein NFAP2 selectively targets early morphogenetic states of Candida albicans and Candidozyma auris, revealing a transient window of susceptibility during filament and pseudohypha formation. Integrated transcriptomic and in vivo analyses indicate that these developmental states may represent context-dependent entry points for NFAP2 activity. In C. albicans, transcriptomic and network analyses indicate the presence of an anabolic, translation-associated gene expression signature, accompanied by suppression of stress-protective pathways, which is associated with increased susceptibility of emerging hyphae to NFAP2 but does not establish a direct causal mechanism. In C. auris, increased susceptibility of pseudohyphal cells occurred without overt transcriptional remodeling, consistent with the characteristically muted gene expression responses of this species, suggesting that NFAP2 sensitivity is governed primarily by biophysical and post-transcriptional mechanisms rather than transcriptional reprogramming. Importantly, morphotype-specific vulnerabilities observed in vitro were reflected in distinct in vivo outcomes in Galleria mellonella, as NFAP2 was well tolerated and provided a moderate, transient survival benefit in pseudohyphal C. auris infections, but not in filamentous C. albicans, where a worsened outcome was observed, consistent with species- and morphotype-dependent activity. Taken together, these results suggest that early morphogenetic states of Candida are stress-sensitive phenotypes associated with increased susceptibility to NFAP2. This work provides a proof-of-concept framework for future investigation of morphotype-associated antifungal vulnerability to peptide-based antifungal strategies.IMPORTANCEDrug-resistant Candida species represent an escalating global health threat; however, most antifungal strategies continue to target fungal growth rather than intrinsic biological vulnerabilities. In this study, we identified early morphogenetic transitions as a shared window of increased susceptibility in both Candida albicans and the highly drug-resistant pathogen Candidozyma (formerly Candida) auris. By integrating transcriptomic profiling with in vivo infection models, we found that NFAP2 exhibits antifungal activity that is influenced by these transient developmental states in a context-dependent manner while remaining well tolerated by the host. We further demonstrated that morphotype-specific stress responses are associated with the divergent sensitivities of C. albicans and C. auris to NFAP2. These results support the concept that fungal morphogenesis may represent a therapeutically actionable process and provide a framework for designing antifungal strategies that target developmental states rather than growth. This strategy may open new opportunities for improving protein- and peptide-based therapies, as well as combination therapies against difficult-to-treat fungal pathogens."

Human immunity to C. albicans infection is thought to be largely dependent on neutrophil reactive oxygen and nitrogen species (ROS/RNS) generation by neutrophils. Despite this, our understanding of innate immune killing and escape by C. albicans is primarily studied in macrophages, and the precise mechanisms of evasion are unclear in neutrophils. Here, we sought to determine the importance of neutrophil reactive nitrogen species (RNS) production during C. albicans infection in vivo. Using a zebrafish model, we found that C. albicans rapidly downregulated neutrophil RNS below basal levels during the first day post-infection, a time at which neutrophil RNS is upregulated in bacterial infections as an important host-defense mechanism, indicating fungal evasion of host neutrophils. We confirmed the downregulation of RNS in human primary neutrophils and with clinical Candida isolates, including emerging human pathogens Candida auris and Candida glabrata. Inducible nitric oxide synthase (iNOS; Nos2 in zebrafish), the enzyme responsible for RNS production, competes with the arginase enzyme for a shared substrate, L-arginine. Using a zebrafish arginase2 transgenic line and a C. albicans car1\u0394 mutant, we showed that both host and fungal arginase contribute to the reduction in neutrophil RNS. Despite pathogen downregulation, upregulation of neutrophil RNS via hypoxia-inducible factor 1\u03b1 (Hif-1\u03b1) stabilization was sufficient to improve host survival following C. albicans infection. Inhibition of Nos2 blocked the host protective effect of Hif-1\u03b1 stabilization. Finally, restoration of neutrophil RNS via Hif-1\u03b1 stabilization was additive to clinically relevant antifungal treatment, increasing survival and clearance of C. albicans infections. Together, these data demonstrate that restoration of the neutrophil RNS response in C. albicans infection improves infection outcomes, highlighting the potential of targeting Hif-1\u03b1 and RNS in host-directed therapies against fungal infections.IMPORTANCECandida albicans is a fungus that normally lives harmlessly in the human body but can cause life-threatening infections in people with weakened immune systems. A key part of the body's defense against this fungus is neutrophils, immune cells that kill microbes using toxic molecules. However, how Candida avoids neutrophil defense is not well understood. Here, we used zebrafish and human immune cells to show that Candida suppresses an important neutrophil defense, reactive nitrogen species (RNS), during infection. Unlike bacteria, which trigger RNS, Candida reduces these protective molecules to below normal levels, helping its survival. This effect was also observed with other disease-causing Candida species. We went on to show that both the host and Candida contribute to this suppression. Importantly, boosting the neutrophil response improved survival and helped clear infection, especially when combined with standard antifungal drugs. These findings suggest new ways to support the immune system alongside existing treatments."

However, the molecular mechanisms underlying its virulence remain incompletely understood. In this study, we performed in vivo transcriptome analysis using an immunosuppressed mouse gastrointestinal infection model to identify genes associated with host adaptation and virulence during infection. By comparing fungal transcriptomes obtained from colonization and dissemination sites with those from\u00a0in vitro cultures, we identified genes that were consistently upregulated during infection. Among these genes, the unfolded protein response regulator HAC1 was selected as a candidate virulence-associated gene for further analysis. Reverse transcription PCR and sequencing analyses revealed that\u00a0HAC1 mRNA in C. auris undergoes an unconventional splicing event of 287 bp that is enhanced under endoplasmic reticulum stress conditions. The excised region spans the annotated open reading frame boundary, suggesting that the translated region of\u00a0HAC1 may require re-evaluation. Notably, a proportion of HAC1 transcripts appeared to be spliced even under non-stress conditions, indicating a detectable basal level of the unfolded protein response. Differences in splicing dynamics were also observed among clade strains. Functional analyses demonstrated that deletion of\u00a0HAC1 increased sensitivity to endoplasmic reticulum stress. The HAC1 deletion mutant also exhibited reduced virulence in both Galleria mellonella and immunosuppressed mouse infection models, as evidenced by delayed host mortality and decreased fungal burdens, respectively. These findings indicate that HAC1 contributes to endoplasmic reticulum stress adaptation and survival in the host environment and identify\u00a0HAC1 as a virulence-associated gene in C. auris. Candida auris is an emerging multidrug-resistant fungal pathogen. Using in vivo transcriptome analysis, we identified HAC1 as a regulator of endoplasmic reticulum stress adaptation and virulence in infection models.

In this study, we employed a targeted drug-repurposing strategy to identify novel indications for existing FDA-approved compounds against C. auris, leading to the identification of Tavaborole as a potent fungistatic agent. Tavaborole displayed robust activity across all five tested clades of C. auris, as well as against Candida albicans and Candida glabrata. To investigate drug resistance mechanisms of C. auris, we applied quantitative proteomics analyses following exposure to Tavaborole and Amphotericin B (AmB), complemented by electron microscopy. Proteomic profiling revealed that C. auris mounts distinct but overlapping adaptive responses to antifungal stress, involving stress response pathways, metabolic reprogramming and amino acid biosynthesis. While Tavaborole primarily induced targeted stress adaptation, AmB triggered a broader, multi-pronged resistance response including oxidative stress mitigation, osmolyte production and metabolic remodeling. Shared alterations in glycogen metabolism and amino acid biosynthesis suggest conserved antifungal adaptation mechanisms. Altogether, this study highlights Tavaborole as a promising antifungal candidate against C. auris, sheds novel insights into drug resistance mechanisms employed by the pathogen and delivers a drug-repurposing procedure highly customizable to target other microorganisms."

This rapid expansion is defined by its unique population structure consisting of six distinct genomic clades with starkly different evolutionary trajectories, phenotypic traits, and clinical risks. We conducted a systematic synthesis of literature from PubMed, Scopus, and Google Scholar (2009-2026), focusing on comparative genomics, clade-specific virulence, and diagnostic accuracy. A total of 64 studies were analyzed to identify patterns in clade divergence and antifungal resistance. Our analysis reveals that C. auris is not a monolithic threat but a complex of diverse lineages with specialized adaptations. Clade I (South Asian) and Clade IV (South American) represent the highest clinical risk due to hyper-virulence and high rates of multi-drug resistant (MDR) strains. In contrast, Clade II (East Asian) was initially associated with localized ear infections; recent genomic data show an expanding pathogenic profile with emerging bloodstream infections. Our review also identifies Clade V (Iranian) as a genetically distinct group and highlights the recent identification of Clade VI (Indomalayan) as a distinct lineage, suggesting a long-standing environmental reservoir. Furthermore, we identify critical \"blind spots\" in automated diagnostic platforms (VITEK\u00ae 2, BD Phoenix) where phenotypic variations in Clades II and III lead to frequent misidentification as Candida haemulonii or Candida famata. This review proposes a \"clade-aware\" framework for public health. While frontline antifungal treatment remains standardized regardless of lineage, we argue that effective long-term management and outbreak containment require integrating genomic surveillance with clade-specific infection control. By identifying high-biofilm clades (Clade I) or hyper-virulent lineages (Clade IV), public health systems can implement more targeted containment strategies, moving toward a precision-based approach to managing this fungal pathogen."

In recent years, these pathogens have increasingly been reported beyond traditional hospital settings, including neonatal intensive care units, long-term care facilities, oncology wards, and post-pandemic critical care environments. International surveillance bodies, including the Centers for Disease Control and Prevention (CDC), European Centre for Disease Prevention and Control (ECDC), World Health Organization (WHO), and regional monitoring networks, have documented escalating antifungal resistance, complex outbreak dynamics, and persistent gaps in infection control implementation. C. auris has emerged as a major etiological agent of healthcare-associated outbreaks, particularly in intensive care and neonatal units. Surveillance data indicate that a high proportion of C. auris isolates exhibit resistance to azoles, often exceeding 80% in some regions, while echinocandin resistance remains variable. Resistance patterns have evolved from predominantly azole resistance to broader multidrug-resistant phenotypes, including treatment-emergent echinocandin resistance. Six genetically distinct clades (I-VI) have been identified, with Clades I, III, and IV associated with large-scale outbreaks, whereas available data suggests that Clades II, V, and VI are more geographically restricted, although evidence for the recently described clades remains limited. C. glabrata is increasingly recognized as a major cause of invasive candidiasis, with rising resistance reported across multiple regions. While reduced azole susceptibility was historically predominant, emerging evidence highlights rising dual azole-echinocandin resistance, adaptive microevolution during antifungal therapy, and biofilm-associated tolerance mechanisms. Despite these advances, significant gaps persist in global resistance surveillance and in the mechanistic understanding of virulence and antifungal adaptation. Current mitigation strategies include antifungal stewardship programs, expanded resistance testing, and strengthened surveillance systems. Advances in rapid diagnostic technologies such as matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry, polymerase chain reaction (PCR)-based assays, and genomic surveillance have improved pathogen identification and outbreak detection, although accessibility remains limited in resource-constrained settings. This review examines emerging epidemiological, genomic, and antifungal resistance trends in C. auris and C. glabrata and highlights key priorities for improving diagnosis, surveillance, stewardship, and management of multidrug-resistant Candida infections."

Data from T\u00fcrkiye remains limited. This retrospective observational study evaluated bacterial and fungal isolates from adult ICU patients at a tertiary hospital from 2016 to 2025. Microorganisms were identified, and antimicrobial susceptibility testing was performed using standardized methods. Resistance patterns were compared between the pre-pandemic (January 2016-February 2020) and post-pandemic (March 2020-May 2025) periods. A total of 2666 patients and 5433 isolates were analyzed. Gram-negative pathogens showed marked increases in resistance: carbapenem and colistin resistance in Klebsiella pneumoniae were significantly higher in the post-pandemic period (69.6% vs. 44.4% and 60.5% vs. 22.5%, respectively; p < 0.001). Resistance rates to multiple antimicrobial agents also increased in Acinetobacter baumannii and Pseudomonas aeruginosa (p < 0.05). Among Gram-positive bacteria, vancomycin-resistant Enterococcus faecium increased from 10% to 47.1%. Candida auris emerged only in the post-pandemic period, showing high resistance to fluconazole (75%) and amphotericin B (36.7%). Significant differences in AMR patterns were observed between the pre- and post-pandemic periods in this ICU population. Higher resistance rates were observed among several clinically important bacterial pathogens, and Candida auris emerged exclusively during the post-pandemic period. Given the study's observational design, these findings should be interpreted as temporal associations rather than evidence of a causal effect of the COVID-19 pandemic. Continued antimicrobial stewardship and infection-control measures remain essential to address the growing burden of AMR."

Despite its increasing detection in healthcare settings worldwide, environmental evidence remains scarce. This study presents the first molecular detection of C. auris DNA in surface waters of T\u00fcrkiye, within the Ramsar-protected Gediz Delta, as part of the national One Health Surveillance Framework. A total of 80 surface-water samples were collected from five wetland ecosystems Tuz Lake, Kulu Lake, G\u00f6ksu Delta (Akg\u00f6l and Paradeniz Lagoons), K\u0131z\u0131l\u0131rmak Delta, and Gediz Delta.

Although antifungal therapy is standard, the host pathways shaping vascular responses-particularly the Notch signaling pathway (NSP)-are not well characterized in this context. In addition, the potential influence of the prostaglandin pathway on vascular NSP-related responses during infection remains unclear. In this study, a rat model of central venous catheter-associated C. albicans infection was used to evaluate microbiological outcomes and vascular NSP-related protein expression. Immunohistochemical analyses were performed to assess Candida immunostaining alongside the expression of Notch receptors (Notch1-3) and ligands (DLL1/4, Jagged1/2) in vascular tissues. Experimental groups included sham, infected control, antifungal-treated (fluconazole, caspofungin, liposomal amphotericin B), and prostaglandin pathway-intervention groups (sulprostone and sulprostone followed by indomethacin). C. albicans infection was associated with higher vascular NSP-related protein expression compared with sham animals.

This yeast shows a high level of resistance to several antifungal agents commonly used to treat systemic infections. The pathogen persists on contaminated surfaces, tolerates hospital-grade disinfectants, survives desiccation and spreads easily through direct or indirect contact. It has been reported on all five continents and is increasingly prevalent in Europe. To determine the distribution and antifungal susceptibility/resistance of Candida auris isolates identified in Europe until January 2025.

Here, we integrate pangenomic analysis with global essentiality screening to establish a foundational understanding of the C. auris genome and identify potential therapeutic targets. We performed pangenome analysis on 695 outbreak strains of C. auris selected to be genetically representative of publicly sequenced genomes. After using BLAST to refine the pangenome, we found that 96.8% of gene families were core, with the remaining high-confidence accessory gene families primarily consisting of gene loss events or clade-specific genes. The high proportion of core genes emphasizes the clonal nature of these outbreak strains, but comparative analysis with the closely related C. haemuli species complex suggested that most of these core genes are functionally dispensible. To examine this hypothesis, we developed a novel insertional mutagenesis approach that leverages the promiscuous integration of linear DNA in the C. auris genome. This global analysis identified 614 high-confidence essential genes. Crucially, nearly one-third of these genes, including the conserved translation initiation factor Sui1, exhibit divergent essentiality patterns compared to the model yeasts Candida albicans and Saccharomyces cerevisiae. These findings highlight organism-specific biology that would be overlooked by orthology alone. By combining pangenomic diversity with functional essentiality, this study provides a comprehensive resource for identifying species-specific determinants of virulence and prioritizing novel targets for antifungal drug development."

NT-a9 is a novel triazole antifungal with potent activity against Candida and Cryptococcus species via strong inhibition of ergosterol biosynthesis. In vitro, NT-a9 exhibited potent and sustained antifungal activity against clinical isolates, with superior potency compared to fluconazole (FLC). It also displayed a prolonged post-antifungal effect (PAFE) against most Candida species, a property rarely seen in conventional azoles. Resistance profiling demonstrated that NT-a9 possesses a high genetic barrier, fully suppressing resistant mutant emergence in Cryptococcus species and maintaining stable susceptibility in Candida albicans during 28 days of continuous exposure. NT-a9 retained potent activity against FLC-resistant Cryptococcus neoformans and multidrug-resistant Candida auris, with minimal influence from drug efflux mechanisms. In murine invasive candidiasis, a single low dose of NT-a9 achieved 100% survival and markedly reduced renal fungal burden, significantly outperforming FLC. NT-a9 also substantially improved survival in mice infected with FLC-resistant C. auris. Mechanistically, NT-a9 binds Erg11 with much higher affinity than FLC by forming key hydrogen bonds with Gly307 and His377, leading to irreversible ergosterol depletion, toxic sterol accumulation, and severe fungal membrane damage. Transcriptomic analysis further confirmed that NT-a9 extensively disrupts sterol biosynthesis and triggers compensatory gene expression that reinforces its antifungal action. As a novel triazole integrating long-lasting efficacy, a high resistance barrier, and potent activity against pan-azole-resistant pathogens, NT-a9 represents a promising clinical candidate for treating IFIs."

Here, we investigated whether laboratory exposure of a clade III clinical C. auris isolate to TCZ could induce cross-resistance to clinical antifungals. Among 17 agrochemicals tested, only TCZ exhibited intrinsic antifungal activity. Brief (48 h) exposure to sub-MIC TCZ (1 \u03bcg/mL) selected variants (6.9% frequency) with cross-resistance to TCZ and fluconazole, but full susceptibility to caspofungin. Exposure to supra-MIC TCZ (8-32 \u03bcg/mL) produced three phenotypic classes: Class 2 (TCZ-R, fluconazole-R) and Class 3 (TCZ-R, fluconazole-R, plus tolerance to caspofungin and micafungin). The frequency of Class 3 increased dose-dependently from 23% to 50% as TCZ concentration rose. RNA-Seq revealed that both classes overexpressed MDR1, TAC1b, UPC2 and FKS1, but Class 2 showed broad ergosterol pathway upregulation, whereas Class 3 exhibited restricted ergosterol activation but downregulation of the sole chitinase gene CHT1 (5.17-fold), a known mechanism of echinocandin tolerance. Unlike the CRS-MIS phenomenon in Candida glabrata, our Class 3 adaptors displayed equal tolerance to both caspofungin and micafungin. Collectively, these findings demonstrate that, in a clade III clinical isolate of C. auris under the tested laboratory conditions, laboratory exposure to an agricultural triazole can rapidly select for clinically relevant azole cross-resistance and echinocandin tolerance in C. auris, suggesting that environmental fungicide use may inadvertently compromise the efficacy of last-line antifungals."

Specifically, it seeks to identify major gaps and challenges in Candidozyma auris (C. auris) classification, diagnostic methods, virulence traits, antifungal therapy, and infection prevention, thereby providing a consolidated evidence base to support improved clinical management, surveillance, and future research. Recent advances have enabled rapid, accurate identification of C. auris using updated MALDI-TOF MS databases and real-time PCR assays. Novel antifungal agents and combination therapies offer potential options against resistant and biofilm-forming C. auris, while recent studies of aggregation, biofilm formation and adhesion, and phenotypic switching have provided new insights into its virulence and persistence in healthcare settings. C. auris exhibits many virulence traits that influence the severity of its infections. Identifying C. auris using conventional microbiological and culture-based methods can be challenging, often leading to delayed diagnoses and inappropriate treatment\u00a0of infections. Its resistance to commonly used antifungal drugs, including azoles, polyenes and echinocandins, further complicates infection control and treatment strategies. C. auris strains are classified into six distinct clades: South Asia, East Asia, South Africa, South America, Iran and Singapore. Each clade exhibits unique genetic characteristics and varying levels of drug resistance. The emergence of C. auris underscores the high priority and urgent need for research, the development of practical molecular-based diagnostic tools, novel antifungal therapies, and robust infection control measures to combat this growing threat."

In this study, three clinical C. auris strains (namely C. auris strain 01, C. auris strain 03, and C. auris strain 13) with distinct origins were characterized to investigate their phenotypic variations and mechanisms of azole resistance. Comprehensive profiling revealed significant inter-strain differences in biofilm formation, cell surface hydrophobicity, adhesion capacity, and phospholipase activity. Testing for antifungal susceptibility showed that the three clinical strains exhibited different minimum inhibitory concentrations for multiple azoles (fluconazole, voriconazole, and itraconazole) and echinocandins (anidulafungin and micafungin). Sequencing identified Y132F mutations in the ERG11 gene of the three clinical strains. Mechanistic investigations demonstrated that fluconazole exposure significantly upregulated the expression of efflux pump genes (CDR1 and CDR2) and the genes encoding their transcriptional regulators (MDR1 and TAC1b). In a murine skin colonization model, comparing data from the standard strain C. auris strain CBS12766 and clinical strains of C. auris strain 03 and C. auris strain 13 exhibited a significantly higher fungal burden of tissue, whereas strain C. auris strain 01 showed an intermediate level. Host immunity response analysis revealed that expression of the IL-1\u03b2 gene was significantly elevated in C. auris strain CBS12766-infected mice, while expression of IL-6 and CXCL-1 genes was predominantly increased in the C. auris strain 01, with TNF-\u03b1 gene expression levels being comparable across all strains. Histopathological examination confirmed local infiltration of inflammatory cells and mild epidermal edema, indicating active host immune engagement. Overall, our findings highlighted substantial phenotypic heterogeneity, different colonization capacities, and differences in expression of inflammatory cytokines among the C. auris strains. Further investigations into fluconazole-response mechanisms identified enhanced efflux pump activity, along with ERG11 gene Y132F mutations and transcription factor modulation among these clinical strains."

However, the molecular mechanisms underlying its virulence remain incompletely understood. In this study, we performed in vivo transcriptome analysis using an immunosuppressed mouse gastrointestinal infection model to identify genes associated with host adaptation and virulence during infection. By comparing fungal transcriptomes obtained from colonization and dissemination sites with those from\u00a0in vitro cultures, we identified genes that were consistently upregulated during infection. Among these genes, the unfolded protein response regulator HAC1 was selected as a candidate virulence-associated gene for further analysis. Reverse transcription PCR and sequencing analyses revealed that\u00a0HAC1 mRNA in C. auris undergoes an unconventional splicing event of 287 bp that is enhanced under endoplasmic reticulum stress conditions. The excised region spans the annotated open reading frame boundary, suggesting that the translated region of\u00a0HAC1 may require re-evaluation. Notably, a proportion of HAC1 transcripts appeared to be spliced even under non-stress conditions, indicating a detectable basal level of the unfolded protein response. Differences in splicing dynamics were also observed among clade strains. Functional analyses demonstrated that deletion of\u00a0HAC1 increased sensitivity to endoplasmic reticulum stress. The HAC1 deletion mutant also exhibited reduced virulence in both Galleria mellonella and immunosuppressed mouse infection models, as evidenced by delayed host mortality and decreased fungal burdens, respectively. These findings indicate that HAC1 contributes to endoplasmic reticulum stress adaptation and survival in the host environment and identify\u00a0HAC1 as a virulence-associated gene in C. auris. Candida auris is an emerging multidrug-resistant fungal pathogen. Using in vivo transcriptome analysis, we identified HAC1 as a regulator of endoplasmic reticulum stress adaptation and virulence in infection models. This study provides new insight into stress-response pathways in C. auris virulence."

In this study, we employed a targeted drug-repurposing strategy to identify novel indications for existing FDA-approved compounds against C. auris, leading to the identification of Tavaborole as a potent fungistatic agent. Tavaborole displayed robust activity across all five tested clades of C. auris, as well as against Candida albicans and Candida glabrata. To investigate drug resistance mechanisms of C. auris, we applied quantitative proteomics analyses following exposure to Tavaborole and Amphotericin B (AmB), complemented by electron microscopy. Proteomic profiling revealed that C. auris mounts distinct but overlapping adaptive responses to antifungal stress, involving stress response pathways, metabolic reprogramming and amino acid biosynthesis. While Tavaborole primarily induced targeted stress adaptation, AmB triggered a broader, multi-pronged resistance response including oxidative stress mitigation, osmolyte production and metabolic remodeling. Shared alterations in glycogen metabolism and amino acid biosynthesis suggest conserved antifungal adaptation mechanisms. Altogether, this study highlights Tavaborole as a promising antifungal candidate against C. auris, sheds novel insights into drug resistance mechanisms employed by the pathogen and delivers a drug-repurposing procedure highly customizable to target other microorganisms."

This rapid expansion is defined by its unique population structure consisting of six distinct genomic clades with starkly different evolutionary trajectories, phenotypic traits, and clinical risks. We conducted a systematic synthesis of literature from PubMed, Scopus, and Google Scholar (2009-2026), focusing on comparative genomics, clade-specific virulence, and diagnostic accuracy. A total of 64 studies were analyzed to identify patterns in clade divergence and antifungal resistance. Our analysis reveals that C. auris is not a monolithic threat but a complex of diverse lineages with specialized adaptations. Clade I (South Asian) and Clade IV (South American) represent the highest clinical risk due to hyper-virulence and high rates of multi-drug resistant (MDR) strains. In contrast, Clade II (East Asian) was initially associated with localized ear infections; recent genomic data show an expanding pathogenic profile with emerging bloodstream infections. Our review also identifies Clade V (Iranian) as a genetically distinct group and highlights the recent identification of Clade VI (Indomalayan) as a distinct lineage, suggesting a long-standing environmental reservoir. Furthermore, we identify critical \"blind spots\" in automated diagnostic platforms (VITEK\u00ae 2, BD Phoenix) where phenotypic variations in Clades II and III lead to frequent misidentification as Candida haemulonii or Candida famata. This review proposes a \"clade-aware\" framework for public health. While frontline antifungal treatment remains standardized regardless of lineage, we argue that effective long-term management and outbreak containment require integrating genomic surveillance with clade-specific infection control. By identifying high-biofilm clades (Clade I) or hyper-virulent lineages (Clade IV), public health systems can implement more targeted containment strategies, moving toward a precision-based approach to managing this fungal pathogen."

In recent years, these pathogens have increasingly been reported beyond traditional hospital settings, including neonatal intensive care units, long-term care facilities, oncology wards, and post-pandemic critical care environments. International surveillance bodies, including the Centers for Disease Control and Prevention (CDC), European Centre for Disease Prevention and Control (ECDC), World Health Organization (WHO), and regional monitoring networks, have documented escalating antifungal resistance, complex outbreak dynamics, and persistent gaps in infection control implementation. C. auris has emerged as a major etiological agent of healthcare-associated outbreaks, particularly in intensive care and neonatal units. Surveillance data indicate that a high proportion of C. auris isolates exhibit resistance to azoles, often exceeding 80% in some regions, while echinocandin resistance remains variable. Resistance patterns have evolved from predominantly azole resistance to broader multidrug-resistant phenotypes, including treatment-emergent echinocandin resistance. Six genetically distinct clades (I-VI) have been identified, with Clades I, III, and IV associated with large-scale outbreaks, whereas available data suggests that Clades II, V, and VI are more geographically restricted, although evidence for the recently described clades remains limited. C. glabrata is increasingly recognized as a major cause of invasive candidiasis, with rising resistance reported across multiple regions. While reduced azole susceptibility was historically predominant, emerging evidence highlights rising dual azole-echinocandin resistance, adaptive microevolution during antifungal therapy, and biofilm-associated tolerance mechanisms. Despite these advances, significant gaps persist in global resistance surveillance and in the mechanistic understanding of virulence and antifungal adaptation. Current mitigation strategies include antifungal stewardship programs, expanded resistance testing, and strengthened surveillance systems. Advances in rapid diagnostic technologies such as matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry, polymerase chain reaction (PCR)-based assays, and genomic surveillance have improved pathogen identification and outbreak detection, although accessibility remains limited in resource-constrained settings. This review examines emerging epidemiological, genomic, and antifungal resistance trends in C. auris and C. glabrata and highlights key priorities for improving diagnosis, surveillance, stewardship, and management of multidrug-resistant Candida infections."

Data from T\u00fcrkiye remains limited. This retrospective observational study evaluated bacterial and fungal isolates from adult ICU patients at a tertiary hospital from 2016 to 2025. Microorganisms were identified, and antimicrobial susceptibility testing was performed using standardized methods. Resistance patterns were compared between the pre-pandemic (January 2016-February 2020) and post-pandemic (March 2020-May 2025) periods. A total of 2666 patients and 5433 isolates were analyzed. Gram-negative pathogens showed marked increases in resistance: carbapenem and colistin resistance in Klebsiella pneumoniae were significantly higher in the post-pandemic period (69.6% vs. 44.4% and 60.5% vs. 22.5%, respectively; p < 0.001). Resistance rates to multiple antimicrobial agents also increased in Acinetobacter baumannii and Pseudomonas aeruginosa (p < 0.05). Among Gram-positive bacteria, vancomycin-resistant Enterococcus faecium increased from 10% to 47.1%. Candida auris emerged only in the post-pandemic period, showing high resistance to fluconazole (75%) and amphotericin B (36.7%). Significant differences in AMR patterns were observed between the pre- and post-pandemic periods in this ICU population. Higher resistance rates were observed among several clinically important bacterial pathogens, and Candida auris emerged exclusively during the post-pandemic period. Given the study's observational design, these findings should be interpreted as temporal associations rather than evidence of a causal effect of the COVID-19 pandemic. Continued antimicrobial stewardship and infection-control measures remain essential to address the growing burden of AMR."

Despite its increasing detection in healthcare settings worldwide, environmental evidence remains scarce. This study presents the first molecular detection of C. auris DNA in surface waters of T\u00fcrkiye, within the Ramsar-protected Gediz Delta, as part of the national One Health Surveillance Framework. A total of 80 surface-water samples were collected from five wetland ecosystems Tuz Lake, Kulu Lake, G\u00f6ksu Delta (Akg\u00f6l and Paradeniz Lagoons), K\u0131z\u0131l\u0131rmak Delta, and Gediz Delta.

Although antifungal therapy is standard, the host pathways shaping vascular responses-particularly the Notch signaling pathway (NSP)-are not well characterized in this context. In addition, the potential influence of the prostaglandin pathway on vascular NSP-related responses during infection remains unclear. In this study, a rat model of central venous catheter-associated C. albicans infection was used to evaluate microbiological outcomes and vascular NSP-related protein expression. Immunohistochemical analyses were performed to assess Candida immunostaining alongside the expression of Notch receptors (Notch1-3) and ligands (DLL1/4, Jagged1/2) in vascular tissues. Experimental groups included sham, infected control, antifungal-treated (fluconazole, caspofungin, liposomal amphotericin B), and prostaglandin pathway-intervention groups (sulprostone and sulprostone followed by indomethacin). C. albicans infection was associated with higher vascular NSP-related protein expression compared with sham animals. Antifungal-treated groups showed lower NSP-related protein expression, while fungicidal agents were associated with absence of fungal growth in catheter and kidney cultures. In the sulprostone-indomethacin-treated group, NSP-related protein expression levels were lower than those in the sulprostone-treated group despite persistent fungal burden. In conclusion, central venous catheter-associated C. albicans infection was associated with altered vascular NSP-related protein expression. Differences in NSP-related protein expression patterns were observed across antifungal- and prostaglandin pathway-intervention groups.

Most isolates were from Spain (n\u2009=\u2009886, 40.44%), Italy (n\u2009=\u2009553, 25.24%), Greece (n\u2009=\u2009214, 9.77%), the United Kingdom (n\u2009=\u2009182, 8.31%) and Russia (n\u2009=\u2009108, 4.93%), accounting for 88.68% of cases. The remaining 248 isolates (11.32%) were reported across 11 other countries. Fluconazole resistance was found in 90.51% (1555/1718), while resistance to amphotericin B and echinocandins was 13.17% (223/1693) and 4.57% (76/1693), respectively. Candida auris has been predominantly detected in Southern Europe, where the majority of clinical isolates exhibit resistance to fluconazole. Consensus is essential for timely diagnosis, targeted treatment and infection control to prevent its spread. New therapeutic options must be explored to manage Candida auris."

Here, we integrate pangenomic analysis with global essentiality screening to establish a foundational understanding of the C. auris genome and identify potential therapeutic targets. We performed pangenome analysis on 695 outbreak strains of C. auris selected to be genetically representative of publicly sequenced genomes. After using BLAST to refine the pangenome, we found that 96.8% of gene families were core, with the remaining high-confidence accessory gene families primarily consisting of gene loss events or clade-specific genes. The high proportion of core genes emphasizes the clonal nature of these outbreak strains, but comparative analysis with the closely related C. haemuli species complex suggested that most of these core genes are functionally dispensible. To examine this hypothesis, we developed a novel insertional mutagenesis approach that leverages the promiscuous integration of linear DNA in the C. auris genome. This global analysis identified 614 high-confidence essential genes. Crucially, nearly one-third of these genes, including the conserved translation initiation factor Sui1, exhibit divergent essentiality patterns compared to the model yeasts Candida albicans and Saccharomyces cerevisiae. These findings highlight organism-specific biology that would be overlooked by orthology alone. By combining pangenomic diversity with functional essentiality, this study provides a comprehensive resource for identifying species-specific determinants of virulence and prioritizing novel targets for antifungal drug development."

Pronounced drug resistance makes treatment failure common, and so does antifungal tolerance, a phenomenon enabling pathogen survival at supra-MIC concentrations without resistance mutations. Here, we uncover a mechanism of antifungal tolerance in C. auris engaging the mitochondrial cytochrome bc1 complex. Deletion of RIP1, a conserved catalytic complex subunit, does not significantly alter the susceptibility to caspofungin or voriconazole. However, rip1\u0394 mutants exhibit a marked reduction in antifungal tolerance across a wide range of supra-MIC concentrations. Transcriptomics reveals the dysregulation of multiple drug resistance and tolerance-related genes in the rip1\u0394 mutant, demonstrating a role for Rip1 in controlling antifungal susceptibility. Targeting cytochrome bc1 function with the fungal-specific inhibitor Inz-5 enhances antifungal action of both voriconazole and caspofungin. Additionally, ablation of RIP1 causes fitness defects, suggesting that cytochrome bc1 is a potential antifungal target against C. auris infections."

C. auris can cause invasive infections associated with high mortality and can colonize patients asymptomatically, which facilitates transmission in health care settings. Since it was first reported in the United States in 2016, C. auris has been identified in multiple states, with increasing numbers of cases reported annually. Monitoring national trends in cases identified through clinical testing and screening for colonization is critical to guide infection prevention and control efforts. 2022-2024. State and jurisdictional health departments voluntarily report clinical and screening C. auris cases to CDC using standardized case definitions of the Council of State and Territorial Epidemiologists. Clinical cases are defined as detection of C. auris from specimens collected for diagnostic purposes; screening cases are defined as detection from colonization screening swabs. Cases were reported to CDC through the Research Electronic Data Capture (REDCap) or Data Collation and Integration for Public Health Event Response (DCIPHER) platforms. Data included patient age and sex, case type, specimen type (for clinical cases), health care facility type, Antimicrobial Resistance Laboratory Network geographic region, and specimen collection date. Analyses were descriptive and limited to cases with specimens collected during 2022-2024. During 2022-2024, a total of 13,507 clinical C. auris cases were reported to CDC, increasing from 2,882 in 2022 to 4,428 in 2023 and 6,197 in 2024, with smaller annual percentage increases over time (53.7% from 2022 to 2023 and 39.9% from 2023 to 2024). Most clinical cases occurred among adults aged \u226545 years (87.8%) and among males (61.0%). The most common specimen types among all clinical cases were urine (31.5%) and blood (30.2%); by year, the proportion of blood as the specimen type was 34.4% in 2022, 30.2% in 2023, and 25.6% in 2024. Most clinical cases were identified through specimens collected in acute care hospitals (76.6%) and long-term acute care hospitals (17.8%).During the same period, a total of 27,853 screening cases were reported to CDC, increasing from 6,226 in 2022 to 9,195 in 2023 and 12,432 in 2024. Screening cases most frequently occurred among adults aged \u226545 years (90.0%) and males (57.9%). Among cases with known facility type, the proportion of specimens collected in acute care hospitals increased from 24.7% in 2022 to 50.7% in 2024, whereas the proportion of specimens collected in long-term acute care hospitals decreased from 56.1% to 35.7% during the same period. The number of clinical and screening C. auris cases reported to CDC increased during 2022-2024, indicating ongoing transmission in U.S. health care settings. Although annual percentage increases in clinical cases declined over time, absolute case counts reported to CDC continued to rise. The increasing proportion of screening cases with specimens collected in acute care hospitals might reflect increased use of screening in acute care hospitals, including screening at admission. Because of increases in the number of reported C. auris cases, sustained infection prevention and control efforts in health care facilities, including adherence to transmission-based precautions, environmental disinfection with agents effective against C. auris, and communication of C. auris status during patient transfers remain essential to preventing clinical infections and colonization. Because this pathogen is frequently resistant to antifungal drugs, continued investment in laboratory capacity and surveillance, including antifungal susceptibility testing and screening of patients at high risk for C. auris infection, can support timely detection and guide prevention strategies. Ongoing public health coordination at federal, state, and local levels is critical to limit further spread and to address emerging antifungal drug resistance."

To describe epidemiologic and laboratory characteristics and trends of HAIs and AMR, 2020-2024, using surveillance and laboratory data submitted by hospitals to the Canadian Nosocomial Infection Surveillance Program (CNISP) and by provincial and territorial laboratories to the National Microbiology Laboratory. Data was collected from 109 Canadian sentinel acute care hospitals between January 1, 2020 and December 31, 2024 for Clostridioides difficile infections (CDI), methicillin-resistant Staphylococcus aureus (MRSA) bloodstream infections (BSIs), vancomycin-resistant Enterococcus (VRE) BSIs (specifically Enterococcus faecalis and Enterococcus faecium), carbapenemase-producing Enterobacterales (CPE) and carbapenemase-producing Acinetobacter baumannii (CPA) infections and colonizations and Candidozyma auris (C. auris; formerly Candida auris) infections. Trend analysis for case counts, incidence rates (rates), outcomes, molecular characterization and AMR profiles are presented.

During this time, infection rates for CPE remained low compared to other HAIs but increased significantly (rates: 0.05-0.20; p=0.03), CPA counts continue to remain very low (n=22 infections) and C. auris counts remained low compared to other HAIs (n=43 isolates). The incidence of MRSA BSIs and CDI remained stable and VRE BSIs and CPE infections increased in the Canadian acute care hospitals participating in CNISP. An increased number of C. auris isolates were identified. Reporting standardized surveillance data to inform the application of infection prevention and control practices in acute care hospitals is critical to help decrease the burden of HAIs and AMR in Canada."

Isolates were analyzed by culture and microscopy, three MALDI-TOF MS platforms, internal transcribed spacer sequencing, Fourier transform infrared (FTIR) spectroscopy and antifungal susceptibility testing. C. viswanathii was repeatedly recovered from blood, urine and bronchoalveolar lavage, while the FilmArray BCID2 panel remained negative. All MALDI-TOF MS systems with updated databases correctly identified the yeast at the species level; identification was confirmed by sequencing. Fourier transform infrared analysis showed clustering of clinical isolates and clearly separated C. viswanathii from related Candida species. All isolates exhibited low MICs to echinocandins and amphotericin B as well as moderately elevated fluconazole MICs (2-4 mg/L). This study supports the use of explicit diagnostic algorithms for rare fungal pathogens in yeast-positive, syndromic panel-negative blood cultures.

In pathogenic fungi, it dynamically governs morphogenesis, stress adaptation, and antifungal drug resistance. Using high-resolution mass spectrometry-based phosphoproteomics, researchers have systematically mapped phosphorylation dynamics in WHO-priority pathogens-Candida albicans, Aspergillus fumigatus, Cryptococcus neoformans, and the multidrug-resistant Candidozyma auris (formerly Candida auris). These studies reveal that thousands of phosphorylation events are coordinately reprogrammed in response to antifungal drug exposure, host-derived oxidative stress, and temperature shifts. Integration of available datasets suggests a \"conserved-core/divergent-output\" organization. Shared kinase hubs like cAMP-PKA, HOG-MAPK and calcineurin are broadly conserved across species. Downstream substrate networks, however, have diverged, producing distinct virulence outputs in each pathogen. Notably, C. auris remains completely uncharacterized at the phosphoproteomic level. This review provides a comprehensive synthesis of the phosphoproteomic landscape across these pathogens, and discusses how phosphoproteomic data are guiding the rational prioritization of kinases and phosphatases as next-generation antifungal drug targets-with direct implications for clinical surveillance and public health."

However, the molecular mechanisms underlying its virulence remain incompletely understood. In this study, we performed in vivo transcriptome analysis using an immunosuppressed mouse gastrointestinal infection model to identify genes associated with host adaptation and virulence during infection. By comparing fungal transcriptomes obtained from colonization and dissemination sites with those from\u00a0in vitro cultures, we identified genes that were consistently upregulated during infection. Among these genes, the unfolded protein response regulator HAC1 was selected as a candidate virulence-associated gene for further analysis. Reverse transcription PCR and sequencing analyses revealed that\u00a0HAC1 mRNA in C. auris undergoes an unconventional splicing event of 287 bp that is enhanced under endoplasmic reticulum stress conditions. The excised region spans the annotated open reading frame boundary, suggesting that the translated region of\u00a0HAC1 may require re-evaluation. Notably, a proportion of HAC1 transcripts appeared to be spliced even under non-stress conditions, indicating a detectable basal level of the unfolded protein response. Differences in splicing dynamics were also observed among clade strains. Functional analyses demonstrated that deletion of\u00a0HAC1 increased sensitivity to endoplasmic reticulum stress. The HAC1 deletion mutant also exhibited reduced virulence in both Galleria mellonella and immunosuppressed mouse infection models, as evidenced by delayed host mortality and decreased fungal burdens, respectively. These findings indicate that HAC1 contributes to endoplasmic reticulum stress adaptation and survival in the host environment and identify\u00a0HAC1 as a virulence-associated gene in C. auris. Candida auris is an emerging multidrug-resistant fungal pathogen. Using in vivo transcriptome analysis, we identified HAC1 as a regulator of endoplasmic reticulum stress adaptation and virulence in infection models. This study provides new insight into stress-response pathways in C. auris virulence."

Evolved strains developed stable resistance to multiple echinocandins, while AR0387 (B8441), originating from MICAevo strain, also acquired increased azole tolerance.

Baicalein (BE), a major bioactive constituent of Scutellaria baicalensis Georgi, exhibits notable antifungal potential, yet its specific molecular mechanisms against C. auris remain poorly elucidated. In this study, we determined the antifungal activity of BE against multiple C. auris isolates, assessed its effects on fungal growth, virulence attributes, adhesion, and biofilm development, validated its in vivo protective efficacy in a Galleria mellonella infection model, and explored the underlying mechanisms via transcriptomic sequencing. BE exerted potent and consistent antifungal activity against all tested strains, with a minimum inhibitory concentration of 1 \u03bcg/mL, minimum fungicidal concentrations of 4-8 \u03bcg/mL, and a sessile minimum inhibitory concentration of 32 \u03bcg/mL. It time- and concentration-dependently suppressed fungal growth, virulence factor expression, adhesion to biological and non-biological surfaces, and biofilm formation, while conferring significant in vivo protection against C. auris infection. Transcriptomic analysis identified 11 adhesion- and biofilm-associated target genes, among which SCF1 and ALS1 served as pivotal regulators. Collectively, BE exerts robust anti-C. auris effects by modulating key target gene expression to interfere with multiple virulence-related processes, providing experimental support for its development as a novel antifungal agent for C. auris infection treatment.IMPORTANCEThe emerging multidrug-resistant fungal pathogen Candida auris has become a critical global public health concern. Its pronounced nosocomial transmissibility, high infection-associated mortality, and extensive cross-resistance to mainstream antifungal agents have created substantial unmet needs in clinical treatment and nosocomial infection control. In this study, we systematically validated the in vitro and in vivo antifungal activity of baicalein against C. auris and elucidated the molecular mechanism underlying its modulation of virulence-related genes. Our findings provide a pivotal experimental basis for the development of novel antifungal therapeutics targeting C. auris infections."

Here, we investigated whether laboratory exposure of a clade III clinical C. auris isolate to TCZ could induce cross-resistance to clinical antifungals. Among 17 agrochemicals tested, only TCZ exhibited intrinsic antifungal activity. Brief (48 h) exposure to sub-MIC TCZ (1 \u03bcg/mL) selected variants (6.9% frequency) with cross-resistance to TCZ and fluconazole, but full susceptibility to caspofungin. Exposure to supra-MIC TCZ (8-32 \u03bcg/mL) produced three phenotypic classes: Class 2 (TCZ-R, fluconazole-R) and Class 3 (TCZ-R, fluconazole-R, plus tolerance to caspofungin and micafungin). The frequency of Class 3 increased dose-dependently from 23% to 50% as TCZ concentration rose. RNA-Seq revealed that both classes overexpressed MDR1, TAC1b, UPC2 and FKS1, but Class 2 showed broad ergosterol pathway upregulation, whereas Class 3 exhibited restricted ergosterol activation but downregulation of the sole chitinase gene CHT1 (5.17-fold), a known mechanism of echinocandin tolerance. Unlike the CRS-MIS phenomenon in Candida glabrata, our Class 3 adaptors displayed equal tolerance to both caspofungin and micafungin. Collectively, these findings demonstrate that, in a clade III clinical isolate of C. auris under the tested laboratory conditions, laboratory exposure to an agricultural triazole can rapidly select for clinically relevant azole cross-resistance and echinocandin tolerance in C. auris, suggesting that environmental fungicide use may inadvertently compromise the efficacy of last-line antifungals."

Disinfectant efficacy is variable, particularly under high organic load, with reports of reduced susceptibility to Candida albicans. The aim of this study was to define the intrinsic chemical susceptibility of Candido auris clades I-IV and assess whether yeasticidal efficacy against Candida albicans predicts activity against Candido auris. Quantitative suspension tests (NEN-EN 13624:2022, dirty conditions) were used to evaluate six disinfectant chemistries: organic acid (lactic acid), halogen (chlorine), quaternary ammonium compounds, alcohol (ethanol), and oxidising agent (hydrogen peroxide). Testing was conducted in two independent laboratories using Candida albicans ATCC 10231 and Candido auris clades (I-IV). All chemistries achieved a \u22654 log10 reduction against Candida albicans and all Candido auris clades at validated conditions, with no consistent clade-dependent differences. Organic acid formulations showed comparable efficacy, highlighting a potential sustainable alternative. Candido auris shows susceptibility comparable with that of Candida albicans. Efficacy is driven by formulation, concentration, and contact time rather than clade variation, supporting formulation-based disinfection strategies for healthcare settings."

Distinct from other clinically prevalent fungal pathogens such as Candida species, C. auris employs unique defense mechanisms against the host immune system, including immune evasion and survival strategies. This review summarizes the distinct strategies used by C. auris to resist host immune responses. In particular, C. auris exhibits pronounced genomic and morphological plasticity, which facilitates rapid adaptation to host-derived stressors. Its modified cell wall, characterized by a thicker mannan layer, efficiently masks immunogenic \u03b2-glucan, thereby reducing immunogenicity. Furthermore, multicellular features, including robust biofilms and unique aggregative forms, enhance colonization, transmission, and stress resistance. C. auris also secretes diverse virulence factors and undergoes adaptive metabolic reprogramming under nutrient limitation, promoting more efficient immune evasion and survival within the host. Collectively, these flexible defensive strategies confer enhanced host immune resistance, contributing to its heightened pathogenicity. This review provides novel perspectives on future research directions and potential therapeutic strategies for managing C. auris infections."

This rapid expansion is defined by its unique population structure consisting of six distinct genomic clades with starkly different evolutionary trajectories, phenotypic traits, and clinical risks. We conducted a systematic synthesis of literature from PubMed, Scopus, and Google Scholar (2009-2026), focusing on comparative genomics, clade-specific virulence, and diagnostic accuracy. A total of 64 studies were analyzed to identify patterns in clade divergence and antifungal resistance. Our analysis reveals that C. auris is not a monolithic threat but a complex of diverse lineages with specialized adaptations. Clade I (South Asian) and Clade IV (South American) represent the highest clinical risk due to hyper-virulence and high rates of multi-drug resistant (MDR) strains. In contrast, Clade II (East Asian) was initially associated with localized ear infections; recent genomic data show an expanding pathogenic profile with emerging bloodstream infections. Our review also identifies Clade V (Iranian) as a genetically distinct group and highlights the recent identification of Clade VI (Indomalayan) as a distinct lineage, suggesting a long-standing environmental reservoir. Furthermore, we identify critical \"blind spots\" in automated diagnostic platforms (VITEK\u00ae 2, BD Phoenix) where phenotypic variations in Clades II and III lead to frequent misidentification as Candida haemulonii or Candida famata. This review proposes a \"clade-aware\" framework for public health. While frontline antifungal treatment remains standardized regardless of lineage, we argue that effective long-term management and outbreak containment require integrating genomic surveillance with clade-specific infection control. By identifying high-biofilm clades (Clade I) or hyper-virulent lineages (Clade IV), public health systems can implement more targeted containment strategies, moving toward a precision-based approach to managing this fungal pathogen."

Prospective observational surveillance study. Tertiary academic hospital in Northern Greece. Hospitalized patients undergoing active MDRO screening based on predefined infection prevention and control criteria. A pathogen-focused analysis was conducted using data from a prospective MDRO surveillance program between October 2024 and January 2025. Screening swabs were obtained from the rectum and groin. Target organisms included multidrug-resistant (MDR) Klebsiella pneumoniae, Pseudomonas aeruginosa, vancomycin-resistant enterococci (VRE), Candida auris, and Acinetobacter spp. Pathogen-specific detection yields were calculated for each anatomical site. Among 1,206 screening swabs, 308 (25.5%) were positive for at least one MDRO. Rectal swabs detected 95.8% of Klebsiella pneumoniae (K. pneumoniae) (92/96), 100% of VRE (59/59), and 66.7% of Pseudomonas aeruginosa (46/69). In contrast, 88.9% of Candida auris cases (24/27) were identified exclusively from groin swabs. Reliance on rectal screening alone would have missed nearly 90% of Candida auris carriers, whereas groin-only screening would have failed to detect most K. pneumoniae and all VRE carriers. Anatomical site selection critically influences MDRO surveillance sensitivity. Rectal screening is optimal for MDROs colonizing the gastrointestinal tract, whereas groin sampling is essential for detecting Candida auris. Pathogen-targeted, site-specific surveillance strategies may substantially improve detection efficiency and optimize infection prevention efforts in high-prevalence hospital settings."

The Centers for Disease Control and Prevention (CDC) has designated it as a pathogen of concern. The World Health Organization (WHO) has listed it in priority list of fungal pathogens. C.\u00a0auris has the ability to spread very fast inside the hospital environment and cause outbreaks worldwide. It has a very high affinity toward skin colonization, especially in the areas like axilla and groin. Based on whole genome sequencing it is classified into five clades. Each clade has different geographical distribution. Often C. auris gets misidentified as other species due to its phylogenetic similarity with C.\u00a0heamulonii. This can only be resolved by establishing diagnosis at molecular levels. Whole genome sequencing and polymerase chain reaction are some of the important molecular diagnostic methods for detection of C. auris. MALDI-TOF-MS is a culture based highly efficient method that is widely being used for C. auris identification. Treatment of C. auris infection depends on effective antifungal therapy, as multidrug resistance is quite common, the drug regime is decided after antifungal sensitivity testing. It is commonly treated with echinocandins and polyenes. Apart from the antifungal therapy it is also important to monitor the fungemia by performing blood cultures. A strict surveillance system can help prevent the disease. Timely screening of hospital personnel carrying the yeast can contain the spread of this organism. Newer antifungal agents are also required as the organism develops resistance very fast."

Despite the recent emergence of at least four distinct clades at the global scale, little remains known about how C. auris is so adept at growing on skin and the key genes and pathways it utilizes to metabolize the scarce nutrients available. Here, we identify the roles that conventional and alternative carbon metabolism genes and metabolic pathways have in facilitating C. auris growth through laboratory-based experiments and bioinformatics analyses. In artificial skin-like media, all four clades of C. auris were more capable of growing than Candida albicans SC5314, a clinically relevant counterpart. By investigating the differential regulation of C. auris when growing in skin-like media as compared to rich fungal media, we uncovered hundreds of genes in multiple metabolic pathways. To further test the mechanisms of these metabolic pathways, we deleted several non-essential gene candidates including FOX2 (B9J08_002847), CAT2 (B9J08_000010), and ICL1 (B9J08_003374). The mutant strains all exhibited abrogated growth in skin-like media and demonstrated nutrient preferences that differed from the wild type. Thus, we propose a model of how C. auris has the capacity to metabolize nutrients that are available on skin by optimizing its metabolic profile. Targeting these metabolic pathways to mitigate C. auris growth on skin is a potential avenue to explore in controlling the spread of this emerging human fungal pathogen. Candida auris is an emerging fungal pathogen with human skin as its primary site of colonization and subsequent transmission. Here, we show the importance of conventional and alternative carbon metabolism for the ability of C. auris to grow in artificial skin-like media. This knowledge provides a better understanding of C. auris metabolism and sheds light on genes and pathways that could be targeted to interfere with persistent skin colonization."

Analysis of 13,314 published genomes revealed that 3104 strains (23.3%) harbor nonsense or frameshift mutations in WOR2, indicating frequent clinical occurrence. Deletion of WOR2 in a clinical strain markedly increased biofilm formation, whereas reintroduction of an intact WOR2 significantly attenuated biofilm development.

This fungal pathogen is notable for its thermotolerance and a strong attachment capability that confers environmental persistence and immune evasion. Here, we compared strains from five clades of C. auris: clade I = South Asia (CDC 387), clade II = East Asia (CDC 381), clade III = Africa (CDC 384), clade IV = South America (CDC 385), and clade V = Iran (CDC 1097) for their ability to regulate cell surface hydrophobicity and biofilm. The hydrophobicity varied for each C. auris clade, with strains 384, 385, and 1097 displaying the highest hydrophobicity levels. C. auris strains had variable biofilm levels when compared among clades and had lower or similar biofilm levels when compared with Candida albicans at different temperatures. Comparison of mass spectrometry analysis of proteolytic digestates of cells from strains with low or high hydrophobicity revealed putative surface hydrophobic proteins. These included homologs to Candida albicans Als3 and IFF proteins, and their contribution to hydrophobicity and biofilm formation was confirmed with gene-deficient (knockout) C. auris strains. We conclude that several proteins contribute to C. auris surface hydrophobicity. Candidozyma auris (Candida auris) is an emerging pathogenic microorganism that is rapidly gaining attention due to outbreaks in health care facilities and its multidrug resistance. Its origin has yet to be determined, but genotypic analyses have pointed toward a simultaneous independent emergence of the different clades, possibly implicating climate change as a major factor in its recent appearance as a fungal pathogen. In 2022, the World Health Organization placed C. auris in the critical priority group as the second greatest fungal threat globally. Due to limited immunological and proteomic studies of C. auris, we sought to elucidate possible virulence mechanisms and identify leading proteins that can be targeted by immunotherapies and new drugs. Using proteomic analysis, we identified 12 lead proteins related to C. auris hydrophobicity and adhesion, implying that these properties are conferred by multiple proteins."

These traits enable it to persist and be continuously transmitted in the environment, posing significant challenges for preventing and controlling clinical infections. Our study aimed to elucidate the phylogenetic relationships of C. auris isolates collected in China, and to explore the tolerance of C. auris to antifungal drugs and disinfectant agents commonly used in hospital. This study also intended to comprehensively characterize the drug resistance genes and amino acid substitutions in C. auris. METHODS: Whole-genome sequencing was used to identify and construct a phylogenetic tree for 8 strains of C. auris. The minimum inhibitory concentration (MIC) and minimum bacterial concentration (MBC) of antifungal agents against C. auris isolates were determined using broth dilution. Quantitative suspension tests were conducted to evaluate the killing effects of different disinfectant agents on C. auris isolates. Resistance genes and mutation sites were identified using bioinformatic analysis. RESULTS: Five isolates of C. auris were closely related to the C. auris B13916 (clade I) and three isolates were closest to B17721 (clade III). All isolates showed resistance to fluconazole; five of them showed reduced susceptibility to amphotericin B. Compared with Candida albicans, benzalkonium chloride, didodecyl dimethylammonium chloride, chlorhexidine gluconate, and hydrogen peroxide showed increased MIC and MBC values against C. auris isolates. Under specific conditions, the anti-fungal effects of benzalkonium chloride, chlorhexidine gluconate, sodium hypochlorite, ethanol, and povidone-iodine were effective. however, didodecyl dimethylammonium chloride and hydrogen peroxide were less effective. C. auris isolates exhibited amino acid substitutions in ERG11, ERG2, ERG4, CIS2, TAC1, and CDR1. They also possessed resistance genes associated with antimicrobial target alterations and efflux pump. CONCLUSIONS: The decreased susceptibility of C. auris to fluconazole, amphotericin B, didodecyl dimethylammonium chloride, and hydrogen peroxide, which could be attributed to resistance genes and single-nucleotide mutations, reminds medical institutions to rationally select the type, concentration, and exposure time of antifungal agents targeting C. auris. The emergence of C. auris resistance to antifungal drugs and disinfectant agents may involve common molecular mechanisms involving nucleotide mutations, requiring further studies."

In this study, we report the synthesis, characterization, and biological evaluation of a guar gum-quercetin bioconjugate designed to improve the practical applicability of quercetin through covalent conjugation with a biocompatible polysaccharide scaffold and a cystamine-based disulfide linker. The formation of the GG-Cys-Quer conjugate was supported by FTIR, 1H/13C NMR, CHNS elemental analysis, degree-of-substitution estimation, SEM, and TGA. The conjugate showed potent antifungal activity against five clinical C. auris isolates, with MIC and MFC values ranging from 0.030 to 0.245 \u00b5g mL-1 and 0.123 to 0.488 \u00b5g mL-1, respectively. Against the resistant isolate MRL6057, GG-Cys-Quer showed an MIC of 0.245 \u00b5g mL-1, whereas caspofungin showed an MIC of 4.0 \u00b5g mL-1 under the same assay conditions. Mechanistic studies showed increased intracellular ROS accumulation, loss of mitochondrial membrane potential, and apoptosis-associated changes, as confirmed by Annexin V/PI staining, with a concentration-dependent increase in late apoptotic/necrotic cell populations at higher exposure levels.

These infections often lead to high mortality because biofilms make the fungi more resistant to antifungal drugs and harder for the immune system to clear. Pathogens such as Candida auris, Candida albicans, and Aspergillus fumigatus are particularly problematic, as they are known to develop multidrug resistance and cause persistent infections in critically ill patients. These biofilms often show a much higher tolerance to standard antifungal drugs and can escape the host body's immune defenses. This makes the infections they cause more persistent and very difficult to treat in clinical practice. Antifungal peptides (AFPs), whether derived from natural host-defense molecules or designed through rational engineering, are emerging as promising options for tackling fungal biofilms. They act through several mechanisms, such as disrupting the fungal cell membrane, blocking early adhesion and morphogenesis, and weakening the extracellular matrix. Importantly, they may also work in synergy with existing antifungal drugs, making treatment more effective. Recent progress in peptide engineering and delivery methods, such as nanocarriers and hydrogel-based systems has enhanced the stability, selectivity, and ability of peptides to target fungal biofilms in experimental models. At the same time, there are important challenges that remain, including their tendency to break down due to proteolytic enzymes, possible cytotoxic effects, difficulties in large scale manufacturing, and regulatory hurdles linked to peptide-based therapies. Overall, AFPs represent a promising and fast developing area of research, but their use in clinical practice is limited. More studies are needed to confirm their safety, effectiveness and practical feasibility for managing biofilm-associated fungal infections."

To analyse the molecular epidemiology and resistance mechanisms of 33 clinical isolates in Shanghai and propose an integrated infection control strategy tailored to metropolitan healthcare settings. Isolates from 19 patients were identified via MALDI-TOF MS and sequencing. Antifungal susceptibility and biofilm formation were assessed. Environmental contamination was evaluated using PCR. Whole-genome sequencing (WGS) was employed to identify resistance mutations and perform phylogenetic analysis. All 33 isolates were fluconazole-resistant. Resistance to amphotericin B and echinocandins was observed in 9 and 4 isolates, respectively. All echinocandin-resistant strains harboured the Fks1-S639F mutation. Phylogenetic analysis revealed that Clade III (South African clade) was the dominant lineage. Colonisation was concentrated in the urinary tract and inguinal regions, while bedside tables were identified as key environmental reservoirs. All strains exhibited strong biofilm-forming capacity. ICU patients serve as primary reservoirs, with transmission driven by interregional movement. The distinct colonisation patterns and environmental hotspots provide specific targets for screening. Integrating PCR-based environmental monitoring with culture methods constitutes an effective strategy. These findings underscore the need for a standardised protocol integrating molecular diagnostics to optimise infection control in urban hospitals."

Prospective observational surveillance study. Tertiary academic hospital in Northern Greece. Hospitalized patients undergoing active MDRO screening based on predefined infection prevention and control criteria. A pathogen-focused analysis was conducted using data from a prospective MDRO surveillance program between October 2024 and January 2025. Screening swabs were obtained from the rectum and groin. Target organisms included multidrug-resistant (MDR) Klebsiella pneumoniae, Pseudomonas aeruginosa, vancomycin-resistant enterococci (VRE), Candida auris, and Acinetobacter spp. Pathogen-specific detection yields were calculated for each anatomical site. Among 1,206 screening swabs, 308 (25.5%) were positive for at least one MDRO. Rectal swabs detected 95.8% of Klebsiella pneumoniae (K. pneumoniae) (92/96), 100% of VRE (59/59), and 66.7% of Pseudomonas aeruginosa (46/69). In contrast, 88.9% of Candida auris cases (24/27) were identified exclusively from groin swabs. Reliance on rectal screening alone would have missed nearly 90% of Candida auris carriers, whereas groin-only screening would have failed to detect most K. pneumoniae and all VRE carriers. Anatomical site selection critically influences MDRO surveillance sensitivity. Rectal screening is optimal for MDROs colonizing the gastrointestinal tract, whereas groin sampling is essential for detecting Candida auris. Pathogen-targeted, site-specific surveillance strategies may substantially improve detection efficiency and optimize infection prevention efforts in high-prevalence hospital settings."

Evolved strains developed stable resistance to multiple echinocandins, while AR0387 (B8441), originating from MICAevo strain, also acquired increased azole tolerance.

Baicalein (BE), a major bioactive constituent of Scutellaria baicalensis Georgi, exhibits notable antifungal potential, yet its specific molecular mechanisms against C. auris remain poorly elucidated. In this study, we determined the antifungal activity of BE against multiple C. auris isolates, assessed its effects on fungal growth, virulence attributes, adhesion, and biofilm development, validated its in vivo protective efficacy in a Galleria mellonella infection model, and explored the underlying mechanisms via transcriptomic sequencing. BE exerted potent and consistent antifungal activity against all tested strains, with a minimum inhibitory concentration of 1 \u03bcg/mL, minimum fungicidal concentrations of 4-8 \u03bcg/mL, and a sessile minimum inhibitory concentration of 32 \u03bcg/mL.

Here, we investigated whether laboratory exposure of a clade III clinical C. auris isolate to TCZ could induce cross-resistance to clinical antifungals. Among 17 agrochemicals tested, only TCZ exhibited intrinsic antifungal activity. Brief (48 h) exposure to sub-MIC TCZ (1 \u03bcg/mL) selected variants (6.9% frequency) with cross-resistance to TCZ and fluconazole, but full susceptibility to caspofungin. Exposure to supra-MIC TCZ (8-32 \u03bcg/mL) produced three phenotypic classes: Class 2 (TCZ-R, fluconazole-R) and Class 3 (TCZ-R, fluconazole-R, plus tolerance to caspofungin and micafungin). The frequency of Class 3 increased dose-dependently from 23% to 50% as TCZ concentration rose. RNA-Seq revealed that both classes overexpressed MDR1, TAC1b, UPC2 and FKS1, but Class 2 showed broad ergosterol pathway upregulation, whereas Class 3 exhibited restricted ergosterol activation but downregulation of the sole chitinase gene CHT1 (5.17-fold), a known mechanism of echinocandin tolerance. Unlike the CRS-MIS phenomenon in Candida glabrata, our Class 3 adaptors displayed equal tolerance to both caspofungin and micafungin. Collectively, these findings demonstrate that, in a clade III clinical isolate of C. auris under the tested laboratory conditions, laboratory exposure to an agricultural triazole can rapidly select for clinically relevant azole cross-resistance and echinocandin tolerance in C. auris, suggesting that environmental fungicide use may inadvertently compromise the efficacy of last-line antifungals."

Distinct from other clinically prevalent fungal pathogens such as Candida species, C. auris employs unique defense mechanisms against the host immune system, including immune evasion and survival strategies. This review summarizes the distinct strategies used by C. auris to resist host immune responses. In particular, C. auris exhibits pronounced genomic and morphological plasticity, which facilitates rapid adaptation to host-derived stressors. Its modified cell wall, characterized by a thicker mannan layer, efficiently masks immunogenic \u03b2-glucan, thereby reducing immunogenicity. Furthermore, multicellular features, including robust biofilms and unique aggregative forms, enhance colonization, transmission, and stress resistance. C. auris also secretes diverse virulence factors and undergoes adaptive metabolic reprogramming under nutrient limitation, promoting more efficient immune evasion and survival within the host.

This rapid expansion is defined by its unique population structure consisting of six distinct genomic clades with starkly different evolutionary trajectories, phenotypic traits, and clinical risks. We conducted a systematic synthesis of literature from PubMed, Scopus, and Google Scholar (2009-2026), focusing on comparative genomics, clade-specific virulence, and diagnostic accuracy. A total of 64 studies were analyzed to identify patterns in clade divergence and antifungal resistance. Our analysis reveals that C. auris is not a monolithic threat but a complex of diverse lineages with specialized adaptations. Clade I (South Asian) and Clade IV (South American) represent the highest clinical risk due to hyper-virulence and high rates of multi-drug resistant (MDR) strains. In contrast, Clade II (East Asian) was initially associated with localized ear infections; recent genomic data show an expanding pathogenic profile with emerging bloodstream infections. Our review also identifies Clade V (Iranian) as a genetically distinct group and highlights the recent identification of Clade VI (Indomalayan) as a distinct lineage, suggesting a long-standing environmental reservoir. Furthermore, we identify critical \"blind spots\" in automated diagnostic platforms (VITEK\u00ae 2, BD Phoenix) where phenotypic variations in Clades II and III lead to frequent misidentification as Candida haemulonii or Candida famata. This review proposes a \"clade-aware\" framework for public health. While frontline antifungal treatment remains standardized regardless of lineage, we argue that effective long-term management and outbreak containment require integrating genomic surveillance with clade-specific infection control. By identifying high-biofilm clades (Clade I) or hyper-virulent lineages (Clade IV), public health systems can implement more targeted containment strategies, moving toward a precision-based approach to managing this fungal pathogen."

C.\u00a0auris has the ability to spread very fast inside the hospital environment and cause outbreaks worldwide. It has a very high affinity toward skin colonization, especially in the areas like axilla and groin. Based on whole genome sequencing it is classified into five clades. Each clade has different geographical distribution. Often C. auris gets misidentified as other species due to its phylogenetic similarity with C.\u00a0heamulonii. This can only be resolved by establishing diagnosis at molecular levels. Whole genome sequencing and polymerase chain reaction are some of the important molecular diagnostic methods for detection of C. auris. MALDI-TOF-MS is a culture based highly efficient method that is widely being used for C. auris identification. Treatment of C. auris infection depends on effective antifungal therapy, as multidrug resistance is quite common, the drug regime is decided after antifungal sensitivity testing. It is commonly treated with echinocandins and polyenes. Apart from the antifungal therapy it is also important to monitor the fungemia by performing blood cultures. A strict surveillance system can help prevent the disease. Timely screening of hospital personnel carrying the yeast can contain the spread of this organism. Newer antifungal agents are also required as the organism develops resistance very fast."

Despite the recent emergence of at least four distinct clades at the global scale, little remains known about how C. auris is so adept at growing on skin and the key genes and pathways it utilizes to metabolize the scarce nutrients available. Here, we identify the roles that conventional and alternative carbon metabolism genes and metabolic pathways have in facilitating C. auris growth through laboratory-based experiments and bioinformatics analyses. In artificial skin-like media, all four clades of C. auris were more capable of growing than Candida albicans SC5314, a clinically relevant counterpart. By investigating the differential regulation of C. auris when growing in skin-like media as compared to rich fungal media, we uncovered hundreds of genes in multiple metabolic pathways. To further test the mechanisms of these metabolic pathways, we deleted several non-essential gene candidates including FOX2 (B9J08_002847), CAT2 (B9J08_000010), and ICL1 (B9J08_003374). The mutant strains all exhibited abrogated growth in skin-like media and demonstrated nutrient preferences that differed from the wild type. Thus, we propose a model of how C. auris has the capacity to metabolize nutrients that are available on skin by optimizing its metabolic profile. Targeting these metabolic pathways to mitigate C. auris growth on skin is a potential avenue to explore in controlling the spread of this emerging human fungal pathogen. Candida auris is an emerging fungal pathogen with human skin as its primary site of colonization and subsequent transmission. Here, we show the importance of conventional and alternative carbon metabolism for the ability of C. auris to grow in artificial skin-like media. This knowledge provides a better understanding of C. auris metabolism and sheds light on genes and pathways that could be targeted to interfere with persistent skin colonization."

This fungal pathogen is notable for its thermotolerance and a strong attachment capability that confers environmental persistence and immune evasion. Here, we compared strains from five clades of C. auris: clade I = South Asia (CDC 387), clade II = East Asia (CDC 381), clade III = Africa (CDC 384), clade IV = South America (CDC 385), and clade V = Iran (CDC 1097) for their ability to regulate cell surface hydrophobicity and biofilm. The hydrophobicity varied for each C. auris clade, with strains 384, 385, and 1097 displaying the highest hydrophobicity levels. C. auris strains had variable biofilm levels when compared among clades and had lower or similar biofilm levels when compared with Candida albicans at different temperatures. Comparison of mass spectrometry analysis of proteolytic digestates of cells from strains with low or high hydrophobicity revealed putative surface hydrophobic proteins. These included homologs to Candida albicans Als3 and IFF proteins, and their contribution to hydrophobicity and biofilm formation was confirmed with gene-deficient (knockout) C. auris strains. We conclude that several proteins contribute to C. auris surface hydrophobicity. Candidozyma auris (Candida auris) is an emerging pathogenic microorganism that is rapidly gaining attention due to outbreaks in health care facilities and its multidrug resistance. Its origin has yet to be determined, but genotypic analyses have pointed toward a simultaneous independent emergence of the different clades, possibly implicating climate change as a major factor in its recent appearance as a fungal pathogen. In 2022, the World Health Organization placed C. auris in the critical priority group as the second greatest fungal threat globally. Due to limited immunological and proteomic studies of C. auris, we sought to elucidate possible virulence mechanisms and identify leading proteins that can be targeted by immunotherapies and new drugs. Using proteomic analysis, we identified 12 lead proteins related to C. auris hydrophobicity and adhesion, implying that these properties are conferred by multiple proteins."

Echinocandin susceptibility of clinical bloodstream C. auris isolates was determined using E-test, and resistance-associated mutations were identified by Sanger sequencing. Biofilm formation under antifungal stress was assessed by crystal violet staining and the 2,3-bis-(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide (XTT) assays. Changes in cell wall components were analyzed using quantitative fluorescence assays, while expression of cell wall biosynthesis-related genes was evaluated by RT-qPCR. Activation of cell wall integrity (CWI) and calcineurin pathways was examined, and the adjunctive effect of calcineurin inhibitors with anidulafungin (ANI) was assessed using disk diffusion and checkerboard assays. Echinocandin resistance in the clinical isolate C. auris 01 was attributed to an S639F mutation in FKS1. ANI treatment-induced cell aggregation and enhanced biofilm formation. It also triggered cell wall remodeling, increasing chitin, mannan, and \u03b2-glucan levels, accompanied by upregulation of \u03b2-glucan synthase (FKS1, FKS2), chitin synthase (CHS1, CHS3), and mannan synthesis (PMR1, PMT1). Furthermore, ANI activated both CWI and calcineurin pathways, indicating adaptive stress responses. Notably, calcineurin inhibition exhibited an additive effect with ANI. These results highlight a multifaceted resistance framework involving structural, signaling, and potential genetic alterations."

These traits enable it to persist and be continuously transmitted in the environment, posing significant challenges for preventing and controlling clinical infections. Our study aimed to elucidate the phylogenetic relationships of C. auris isolates collected in China, and to explore the tolerance of C. auris to antifungal drugs and disinfectant agents commonly used in hospital. This study also intended to comprehensively characterize the drug resistance genes and amino acid substitutions in C. auris. METHODS: Whole-genome sequencing was used to identify and construct a phylogenetic tree for 8 strains of C. auris. The minimum inhibitory concentration (MIC) and minimum bacterial concentration (MBC) of antifungal agents against C. auris isolates were determined using broth dilution. Quantitative suspension tests were conducted to evaluate the killing effects of different disinfectant agents on C. auris isolates. Resistance genes and mutation sites were identified using bioinformatic analysis. RESULTS: Five isolates of C. auris were closely related to the C. auris B13916 (clade I) and three isolates were closest to B17721 (clade III). All isolates showed resistance to fluconazole; five of them showed reduced susceptibility to amphotericin B. Compared with Candida albicans, benzalkonium chloride, didodecyl dimethylammonium chloride, chlorhexidine gluconate, and hydrogen peroxide showed increased MIC and MBC values against C. auris isolates. Under specific conditions, the anti-fungal effects of benzalkonium chloride, chlorhexidine gluconate, sodium hypochlorite, ethanol, and povidone-iodine were effective. however, didodecyl dimethylammonium chloride and hydrogen peroxide were less effective. C. auris isolates exhibited amino acid substitutions in ERG11, ERG2, ERG4, CIS2, TAC1, and CDR1. They also possessed resistance genes associated with antimicrobial target alterations and efflux pump. CONCLUSIONS: The decreased susceptibility of C. auris to fluconazole, amphotericin B, didodecyl dimethylammonium chloride, and hydrogen peroxide, which could be attributed to resistance genes and single-nucleotide mutations, reminds medical institutions to rationally select the type, concentration, and exposure time of antifungal agents targeting C. auris. The emergence of C. auris resistance to antifungal drugs and disinfectant agents may involve common molecular mechanisms involving nucleotide mutations, requiring further studies."

In this study, we report the synthesis, characterization, and biological evaluation of a guar gum-quercetin bioconjugate designed to improve the practical applicability of quercetin through covalent conjugation with a biocompatible polysaccharide scaffold and a cystamine-based disulfide linker. The formation of the GG-Cys-Quer conjugate was supported by FTIR, 1H/13C NMR, CHNS elemental analysis, degree-of-substitution estimation, SEM, and TGA. The conjugate showed potent antifungal activity against five clinical C. auris isolates, with MIC and MFC values ranging from 0.030 to 0.245 \u00b5g mL-1 and 0.123 to 0.488 \u00b5g mL-1, respectively. Against the resistant isolate MRL6057, GG-Cys-Quer showed an MIC of 0.245 \u00b5g mL-1, whereas caspofungin showed an MIC of 4.0 \u00b5g mL-1 under the same assay conditions. Mechanistic studies showed increased intracellular ROS accumulation, loss of mitochondrial membrane potential, and apoptosis-associated changes, as confirmed by Annexin V/PI staining, with a concentration-dependent increase in late apoptotic/necrotic cell populations at higher exposure levels. Ultrastructural analysis further revealed membrane deformation, pore formation, and cellular collapse, supporting severe fungal cell damage following treatment. In mammalian L929 fibroblasts, GG-Cys-Quer maintained >85% cell viability at MFC-level exposure, indicating preliminary in vitro cytocompatibility. Overall, these findings demonstrate that GG-Cys-Quer is a structurally characterized guar gum-quercetin conjugate with strong in vitro antifungal activity against C. auris and a mechanism involving oxidative stress, mitochondrial dysfunction, and apoptosis-associated fungal cell death. Further side-by-side studies with free quercetin, linker controls, guar gum controls, and in vivo models are required to define the specific contribution of conjugation and assess translational potential."

These infections often lead to high mortality because biofilms make the fungi more resistant to antifungal drugs and harder for the immune system to clear. Pathogens such as Candida auris, Candida albicans, and Aspergillus fumigatus are particularly problematic, as they are known to develop multidrug resistance and cause persistent infections in critically ill patients. These biofilms often show a much higher tolerance to standard antifungal drugs and can escape the host body's immune defenses. This makes the infections they cause more persistent and very difficult to treat in clinical practice. Antifungal peptides (AFPs), whether derived from natural host-defense molecules or designed through rational engineering, are emerging as promising options for tackling fungal biofilms. They act through several mechanisms, such as disrupting the fungal cell membrane, blocking early adhesion and morphogenesis, and weakening the extracellular matrix. Importantly, they may also work in synergy with existing antifungal drugs, making treatment more effective. Recent progress in peptide engineering and delivery methods, such as nanocarriers and hydrogel-based systems has enhanced the stability, selectivity, and ability of peptides to target fungal biofilms in experimental models. At the same time, there are important challenges that remain, including their tendency to break down due to proteolytic enzymes, possible cytotoxic effects, difficulties in large scale manufacturing, and regulatory hurdles linked to peptide-based therapies. Overall, AFPs represent a promising and fast developing area of research, but their use in clinical practice is limited. More studies are needed to confirm their safety, effectiveness and practical feasibility for managing biofilm-associated fungal infections."

Its dissemination is driven by patient movement and asymptomatic carriers. However, molecular epidemiological studies linking imported cases to local strains in large metropolitan areas remain limited. To analyse the molecular epidemiology and resistance mechanisms of 33 clinical isolates in Shanghai and propose an integrated infection control strategy tailored to metropolitan healthcare settings. Isolates from 19 patients were identified via MALDI-TOF MS and sequencing. Antifungal susceptibility and biofilm formation were assessed. Environmental contamination was evaluated using PCR. Whole-genome sequencing (WGS) was employed to identify resistance mutations and perform phylogenetic analysis. All 33 isolates were fluconazole-resistant. Resistance to amphotericin B and echinocandins was observed in 9 and 4 isolates, respectively. All echinocandin-resistant strains harboured the Fks1-S639F mutation. Phylogenetic analysis revealed that Clade III (South African clade) was the dominant lineage. Colonisation was concentrated in the urinary tract and inguinal regions, while bedside tables were identified as key environmental reservoirs. All strains exhibited strong biofilm-forming capacity. ICU patients serve as primary reservoirs, with transmission driven by interregional movement. The distinct colonisation patterns and environmental hotspots provide specific targets for screening. Integrating PCR-based environmental monitoring with culture methods constitutes an effective strategy. These findings underscore the need for a standardised protocol integrating molecular diagnostics to optimise infection control in urban hospitals."

We show that the phagocytosis of C. auris cells by primary human macrophages involves the formation of dot-like F-actin-rich structures at C. auris-containing phagosomes that we characterize as phagocytic podosomes. We analyze the composition, architecture, and dynamics of these structures, showing that they constitute a specific adaptation of the phagocytic actin network. The disruption of phagocytic podosomes is associated with reduced internalization of C. auris and delayed phagosomal maturation. Our data provide detailed insights into cytoskeletal rearrangements upon internalization of Candida by immune cells while also demonstrating that the actin network within phagocytic cups is not necessarily uniform and continuous. At the same time, we identify C. auris as a pathophysiologically relevant target whose internalization involves the formation of phagocytic podosomes."

In recent years, these pathogens have increasingly been reported beyond traditional hospital settings, including neonatal intensive care units, long-term care facilities, oncology wards, and post-pandemic critical care environments. International surveillance bodies, including the Centers for Disease Control and Prevention (CDC), European Centre for Disease Prevention and Control (ECDC), World Health Organization (WHO), and regional monitoring networks, have documented escalating antifungal resistance, complex outbreak dynamics, and persistent gaps in infection control implementation. C. auris has emerged as a major etiological agent of healthcare-associated outbreaks, particularly in intensive care and neonatal units. Surveillance data indicate that a high proportion of C. auris isolates exhibit resistance to azoles, often exceeding 80% in some regions, while echinocandin resistance remains variable. Resistance patterns have evolved from predominantly azole resistance to broader multidrug-resistant phenotypes, including treatment-emergent echinocandin resistance. Six genetically distinct clades (I-VI) have been identified, with Clades I, III, and IV associated with large-scale outbreaks, whereas available data suggests that Clades II, V, and VI are more geographically restricted, although evidence for the recently described clades remains limited. C. glabrata is increasingly recognized as a major cause of invasive candidiasis, with rising resistance reported across multiple regions. While reduced azole susceptibility was historically predominant, emerging evidence highlights rising dual azole-echinocandin resistance, adaptive microevolution during antifungal therapy, and biofilm-associated tolerance mechanisms. Despite these advances, significant gaps persist in global resistance surveillance and in the mechanistic understanding of virulence and antifungal adaptation. Current mitigation strategies include antifungal stewardship programs, expanded resistance testing, and strengthened surveillance systems. Advances in rapid diagnostic technologies such as matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry, polymerase chain reaction (PCR)-based assays, and genomic surveillance have improved pathogen identification and outbreak detection, although accessibility remains limited in resource-constrained settings. This review examines emerging epidemiological, genomic, and antifungal resistance trends in C. auris and C. glabrata and highlights key priorities for improving diagnosis, surveillance, stewardship, and management of multidrug-resistant Candida infections."

The prevalence of fungal infections has significantly increased on a global scale, adversely impacting human health. Candida species remain among the most prevalent and widely spread opportunistic fungi, with Candida auris emerging as a notorious hospital-acquired pathogen. This fungal pathogen causes nosocomial bloodstream infections (BSI), coupled with a high in-hospital death rate and significant multidrug-resistance (MDR). Standard quaternary ammonium compounds (Quats), are often ineffective, requiring the use of Environmental Protection Agency (EPA)-registered hospital-grade disinfectants. Routine laboratory procedures often fail to efficiently identify the fungi, making it difficult to predict the infection\u2019s true severity. Hence, molecular-based methods are now considered the gold standard for rapid identification. Despite the availability of approved drugs, their efficacy is questionable due to the emerging drug resistance within the fungal population. The organism appears to acquire drug resistance quickly. While echinocandins remain first-line therapy, the emergence of echinocandin-or pan-resistant cases indicates that treating pan-resistant strains would be particularly tricky, if not unfeasible. This underscores the urgent need for enhanced infection control, improved point-of-care diagnostics, and the development of novel therapeutic strategies. This article highlights the crucial aspects of epidemiology, identification techniques, drug resistance mechanisms, treatments, and challenges associated with C. auris infections. Understanding these interconnected aspects is essential for optimizing clinical management and mitigating the escalating public health crisis posed by this tenacious pathogen."

Phenotypically, the pathogen displays significant clade-dependent diversity, including variable biofilm formation, aggregation, and skin colonization capabilities.\n\n### [ABSTRACT & REWRITTEN CLAIM]\n*Candida auris* acts as a high-priority, multidrug-resistant fungal pathogen with complex regulatory mechanisms. Research identifies the importance of ergosterol biosynthesis, efflux pump activity (e.g., CDR1, MDR1), and mitochondrial adaptation (e.g., cytochrome bc1) in maintaining viability under antifungal pressure. Morphological plasticity, specifically the ability to transition between yeast, aggregative, and pseudohyphal forms, serves as a mechanism for immune evasion and environmental persistence.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe pathogenic profile of *Candida auris* is defined by its evolutionary divergence into distinct clades, each exhibiting unique molecular signatures and virulence traits. Its resistance to conventional antifungals\u2014including azoles, polyenes, and echinocandins\u2014is driven by both canonical point mutations (e.g., *ERG11* and *FKS1* mutations) and structural genomic variations such as segmental duplications. The ability of *C. auris* to persist in hospital settings is linked to its robust biofilm-forming capacity, regulated by transcription factors such as *WOR2*, and its unique skin-tropic behavior supported by specific carbon metabolism pathways and carbonic anhydrase activity. Host interaction is mediated by the suppression of neutrophil reactive nitrogen species and the exploitation of glucose-starvation-induced cell damage.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   The transcription factor *WOR2* acts as a negative regulator of biofilm formation; its inactivation is observed in clinical strains to enhance persistence.\n*   *Candida auris* suppresses host innate immune defenses by downregulating neutrophil reactive nitrogen species to below basal levels.\n*   The carbonic anhydrase *Nce103* is essential for maintaining fitness in nutrient-limited environments and sustaining amphotericin B resistance.\n*   Segmental duplications, rather than just point mutations, serve as a predominant, non-mutational driver of multidrug resistance.\n*   Extracellular vesicles (EVs) export metabolites linked to nucleotide salvage and amino acid metabolism, serving as a mechanism for population-level stress adaptation.\n*   *C. auris* exhibits \"morphotype-specific vulnerabilities,\" where transient developmental states (filamentous or pseudohyphal) represent entry points for peptide-based therapies.\n*   Nutrient limitation in the host environment triggers *NINJ1*-dependent macrophage lysis, facilitating fungal escape.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Its biological success is rooted in a robust, multi-faceted adaptive capacity. Recent molecular research identifies distinct genomic strategies employed by the pathogen to navigate therapeutic pressure. Specifically, structural variations, such as those within the ERG11 locus, drive azole resistance, while supernumerary chromosomes contribute to echinocandin tolerance. Furthermore, internal regulatory systems, including the unfolded protein response and specific mitochondrial complexes, enable C. auris to maintain viability under host-imposed stress. The pathogen\u2019s ability to manipulate the host immune environment\u2014specifically by suppressing reactive nitrogen species\u2014underscores its sophisticated virulence. Surveillance data indicate that environmental reservoirs and hospital-associated colonization remain primary drivers of dissemination.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   C. auris employs non-mutational mechanisms of resistance, specifically segmental duplications of genomic regions, to circumvent antifungal activity.\n*   The pathogen displays clade-specific geographic distribution and resistance profiles, complicating universal treatment protocols.\n*   C. auris can persist on non-living environmental surfaces and skin, exhibiting tolerance to standard hospital disinfectants.\n*   A significant proportion of the C. auris genome consists of core gene families, yet many are functionally dispensable under experimental conditions.\n*   C. auris exhibits a unique ability to manipulate host neutrophil responses by suppressing reactive nitrogen species (RNS) production.\n*   Environmental surveillance has detected C. auris DNA in surface waters, indicating potential reservoirs outside traditional clinical settings.\n*   Cross-kingdom interactions (e.g., mycoviruses) and abiotic stress may influence the thermal tolerance and fitness of the pathogen.\n*   Phenotypic variation in C. auris frequently results in misidentification by standard diagnostic automated systems, often being mislabeled as other yeast species.\n*   Early morphogenetic states of C. auris represent a transient vulnerability to specific antifungal proteins.\n*   The metabolic regulation by mitochondrial proteins is critical for tolerance, with specific deletions leading to fitness defects.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Pathogenic mechanisms include biofilm formation, metabolic adaptation to skin, cell wall remodeling, and unique immune evasion strategies, necessitating integrated molecular surveillance and novel therapeutic targeting.\n\n### [INTRODUCTION & JUSTIFICATION]\n*Candida auris* has emerged as a global public health crisis, defined by its rapid nosocomial transmission and multidrug-resistant profile. The organism demonstrates high genomic plasticity across six recognized clades. Adaptation to host environments, particularly the skin, is facilitated by a robust metabolic profile capable of utilizing scarce nutrients in skin-like conditions. Resilience against chemical decontamination and antifungal therapy is multi-factorial, involving efflux pump upregulation (CDR1, MDR1), mutations in target genes like *ERG11* and *FKS1*, and adaptive remodeling of the extracellular matrix. Host immunity is countered by unique cell wall architectures and aggregative growth forms, necessitating a One Health surveillance strategy.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   *Candida auris* colonization shows a distinct predilection for the groin and axillary regions compared to other *Candida* species.\n*   Loss-of-function mutations in the *WOR2* locus are significantly correlated with enhanced biofilm formation capabilities.\n*   *Candida auris* displays unexpected environmental reservoirs, including wastewater and coastal wetlands, suggesting a sapronotic ecology.\n*   While echinocandin resistance is often associated with fitness costs in other fungi, *Candida auris* maintains virulence even after developing resistance mutations.\n*   \"Phagocytic podosomes\" represent a novel actin-rich mechanism utilized by human macrophages for the uptake of *Candida auris*.\n*   Standard diagnostic platforms (VITEK 2, BD Phoenix) frequently suffer from blind spots, resulting in misidentification as *Candida haemulonii* or *Candida famata*.\n*   Environmental disinfectant failure against biofilms is not primarily clade-dependent but driven by formulation and contact time.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

However, rip1\u0394 mutants exhibit a marked reduction in antifungal tolerance across a wide range of supra-MIC concentrations.\nMechanistic studies showed increased intracellular ROS accumulation, loss of mitochondrial membrane potential, and apoptosis-associated changes, as confirmed by Annexin V/PI staining, with a concentration-dependent increase in late apoptotic/necrotic cell populations at higher exposure levels.\nFurther investigations into fluconazole-response mechanisms identified enhanced efflux pump activity, along with ERG11 gene Y132F mutations and transcription factor modulation among these clinical strains.\nWe identify recurrent CNV hotspots, with segmental duplications representing a predominant mode of genome variation. Small duplications encompassing ERG11 arise at high frequency and frequently co-occur with drug resistance-associated ERG11 mutations, collectively enhancing azole resistance.\nC. albicans rapidly downregulated neutrophil RNS below basal levels during the first day post-infection, a time at which neutrophil RNS is upregulated in bacterial infections as an important host-defense mechanism, indicating fungal evasion of host neutrophils. We confirmed the downregulation of RNS in human primary neutrophils and with clinical Candida isolates, including emerging human pathogens Candida auris and Candida glabrata.\nIn C. auris, increased susceptibility of pseudohyphal cells occurred without overt transcriptional remodeling, consistent with the characteristically muted gene expression responses of this species, suggesting that NFAP2 sensitivity is governed primarily by biophysical and post-transcriptional mechanisms rather than transcriptional reprogramming.\nReverse transcription PCR and sequencing analyses revealed that HAC1 mRNA in C. auris undergoes an unconventional splicing event of 287 bp that is enhanced under endoplasmic reticulum stress conditions.\nProteomic profiling revealed that C. auris mounts distinct but overlapping adaptive responses to antifungal stress, involving stress response pathways, metabolic reprogramming and amino acid biosynthesis.\nGenomic analyses show that the clinical isolates with enhanced biofilm formation ability carry a loss-of-function mutation in the WOR2 locus, which encodes a white-opaque switching regulator in Candida species.\nEvidence suggests that mannan-mediated masking of pathogen-associated molecular patterns (PAMPs) in the aggregative phenotype may contribute to persistence and reduced virulence in the host.\nThe antifungal mechanism of compound 9 involves cell membrane disruption and intracellular ROS accumulation.\nIn glucose-starved macrophages, NINJ1 ruptures membranes independently of known cell death programs. Consistently, NINJ1 is the dominant effector of fungal-induced macrophage damage amongst host cell death factors.\nExport of these metabolites via EVs may support population-level coordination, biofilm remodeling, and modulation of host immune responses, contributing to echinocandin tolerance.\nNotably, the \u0394hgt13 strain exhibited markedly increased FLC resistance, concomitant with reduced intracellular FLC accumulation and decreased membrane permeability.\nFluconazole induces significant upregulation of CDT1 through the calcineurin signalling pathway. Cdt1, beyond its canonical calcium-pumping function, has evolved another function in mediating fluconazole efflux through its fluconazole-induced, calcineurin- and ATP hydrolysis-dependent plasma membrane localization.\nA key question in C. auris biology is how clinical isolates acquire amphotericin B resistance. Here we demonstrate that a carbonic sensing pathway (CSP) contributes to amphotericin B resistance by modulating mitochondrial energy functions in clinical C. auris isolates.\nThe mutant strains all exhibited abrogated growth in skin-like media and demonstrated nutrient preferences that differed from the wild type. Thus, we propose a model of how C. auris has the capacity to metabolize nutrients that are available on skin by optimizing its metabolic profile.\nTranscriptomic profiling of drug-resistant isolates under antifungal and stress conditions identifies previously uncharacterized adaptation mechanisms, including differential regulation of ribosomal assembly pathways and cell cycle checkpoints.\nNT-a9 is a novel triazole antifungal with potent activity against Candida and Cryptococcus species via strong inhibition of ergosterol biosynthesis.\nExposure to supra-MIC TCZ (8-32 \u03bcg/mL) produced three phenotypic classes: Class 2 (TCZ-R, fluconazole-R) and Class 3 (TCZ-R, fluconazole-R, plus tolerance to caspofungin and micafungin).\nC. auris strains are classified into six distinct clades: South Asia, East Asia, South Africa, South America, Iran and Singapore.\nSequencing identified Y132F mutations in the ERG11 gene of the three clinical strains.\nFunctional analyses demonstrated that deletion of HAC1 increased sensitivity to endoplasmic reticulum stress.\nProteomic profiling revealed that C. auris mounts distinct but overlapping adaptive responses to antifungal stress, involving stress response pathways, metabolic reprogramming and amino acid biosynthesis.\nClade I (South Asian) and Clade IV (South American) represent the highest clinical risk due to hyper-virulence and high rates of multi-drug resistant (MDR) strains.\nResistance patterns have evolved from predominantly azole resistance to broader multidrug-resistant phenotypes, including treatment-emergent echinocandin resistance.\nCandida auris emerged only in the post-pandemic period, showing high resistance to fluconazole (75%) and amphotericin B (36.7%).\nC. auris DNA was detected in one sample (1.25%), specifically from the Gediz Delta (Sample No. 5651, 38.523\u00b0 N, 26.892\u00b0 E), with Ct values 33.8-37.2 confirmed by sequencing.\nAntifungal-treated groups showed lower NSP-related protein expression, while fungicidal agents were associated with absence of fungal growth in catheter and kidney cultures.\nFluconazole resistance was found in 90.51% (1555/1718), while resistance to amphotericin B and echinocandins was 13.17% (223/1693) and 4.57% (76/1693), respectively.\nTo examine this hypothesis, we developed a novel insertional mutagenesis approach that leverages the promiscuous integration of linear DNA in the C. auris genome. This global analysis identified 614 high-confidence essential genes.\nNT-a9 is a novel triazole antifungal with potent activity against Candida and Cryptococcus species via strong inhibition of ergosterol biosynthesis.\nExposure to supra-MIC TCZ (8-32 \u03bcg/mL) produced three phenotypic classes: Class 2 (TCZ-R, fluconazole-R) and Class 3 (TCZ-R, fluconazole-R, plus tolerance to caspofungin and micafungin).\nC. auris strains are classified into six distinct clades: South Asia, East Asia, South Africa, South America, Iran and Singapore.\nSequencing identified Y132F mutations in the ERG11 gene of the three clinical strains.\nFunctional analyses demonstrated that deletion of HAC1 increased sensitivity to endoplasmic reticulum stress.\nProteomic profiling revealed that C. auris mounts distinct but overlapping adaptive responses to antifungal stress, involving stress response pathways, metabolic reprogramming and amino acid biosynthesis.\nClade I (South Asian) and Clade IV (South American) represent the highest clinical risk due to hyper-virulence and high rates of multi-drug resistant (MDR) strains.\nResistance patterns have evolved from predominantly azole resistance to broader multidrug-resistant phenotypes, including treatment-emergent echinocandin resistance.\nCandida auris emerged only in the post-pandemic period, showing high resistance to fluconazole (75%) and amphotericin B (36.7%).\nC. auris DNA was detected in one sample (1.25%), specifically from the Gediz Delta (Sample No. 5651, 38.523\u00b0 N, 26.892\u00b0 E), with Ct values 33.8-37.2 confirmed by sequencing.\nAntifungal-treated groups showed lower NSP-related protein expression, while fungicidal agents were associated with absence of fungal growth in catheter and kidney cultures.\nFluconazole resistance was found in 90.51% (1555/1718), while resistance to amphotericin B and echinocandins was 13.17% (223/1693) and 4.57% (76/1693), respectively.\nTo examine this hypothesis, we developed a novel insertional mutagenesis approach that leverages the promiscuous integration of linear DNA in the C. auris genome.

caspofungin.\nThe number of clinical and screening C. auris cases reported to CDC increased during 2022-2024, indicating ongoing transmission in U.S. health care settings.\nCandidozyma auris (Candida auris), first identified in 2022, rapidly became endemic, accounting for 29.5% of isolates in the post-COVID era and exhibiting uniform resistance to fluconazole.\n30-day mortality was 24%, and 90-day mortality was 46%.\nMost isolates showed susceptibility to voriconazole and caspofungin, while varying percentages of susceptibility to fluconazole were observed, especially in C. glabrata and C. auris.\nAn increased number of C. auris isolates were identified.\nAll MALDI-TOF MS systems with updated databases correctly identified the yeast at the species level; identification was confirmed by sequencing.\nWhole-genome sequencing revealed clinically relevant mutations in FKS1, as well as changes in genes involved in ergosterol biosynthesis (ERG3), amino acid metabolism, and PKA signaling.\nTranscriptomic analysis identified 11 adhesion- and biofilm-associated target genes, among which SCF1 and ALS1 served as pivotal regulators.\nBrief (48 h) exposure to sub-MIC TCZ (1

NT-a9 is a novel triazole antifungal with potent activity against Candida and Cryptococcus species via strong inhibition of ergosterol biosynthesis. In vitro, NT-a9 exhibited potent and sustained antifungal activity against clinical isolates, with superior potency compared to fluconazole (FLC). It also displayed a prolonged post-antifungal effect (PAFE) against most Candida species, a property rarely seen in conventional azoles. Resistance profiling demonstrated that NT-a9 possesses a high genetic barrier, fully suppressing resistant mutant emergence in Cryptococcus species and maintaining stable susceptibility in Candida albicans during 28 days of continuous exposure. NT-a9 retained potent activity against FLC-resistant Cryptococcus neoformans and multidrug-resistant Candida auris, with minimal influence from drug efflux mechanisms. In murine invasive candidiasis, a single low dose of NT-a9 achieved 100% survival and markedly reduced renal fungal burden, significantly outperforming FLC. NT-a9 also substantially improved survival in mice infected with FLC-resistant C. auris. Mechanistically, NT-a9 binds Erg11 with much higher affinity than FLC by forming key hydrogen bonds with Gly307 and His377, leading to irreversible ergosterol depletion, toxic sterol accumulation, and severe fungal membrane damage. Transcriptomic analysis further confirmed that NT-a9 extensively disrupts sterol biosynthesis and triggers compensatory gene expression that reinforces its antifungal action. As a novel triazole integrating long-lasting efficacy, a high resistance barrier, and potent activity against pan-azole-resistant pathogens, NT-a9 represents a promising clinical candidate for treating IFIs."

Here, we investigated whether laboratory exposure of a clade III clinical C. auris isolate to TCZ could induce cross-resistance to clinical antifungals. Among 17 agrochemicals tested, only TCZ exhibited intrinsic antifungal activity. Brief (48 h) exposure to sub-MIC TCZ (1 \u03bcg/mL) selected variants (6.9% frequency) with cross-resistance to TCZ and fluconazole, but full susceptibility to caspofungin. Exposure to supra-MIC TCZ (8-32 \u03bcg/mL) produced three phenotypic classes: Class 2 (TCZ-R, fluconazole-R) and Class 3 (TCZ-R, fluconazole-R, plus tolerance to caspofungin and micafungin). The frequency of Class 3 increased dose-dependently from 23% to 50% as TCZ concentration rose. RNA-Seq revealed that both classes overexpressed MDR1, TAC1b, UPC2 and FKS1, but Class 2 showed broad ergosterol pathway upregulation, whereas Class 3 exhibited restricted ergosterol activation but downregulation of the sole chitinase gene CHT1 (5.17-fold), a known mechanism of echinocandin tolerance. Unlike the CRS-MIS phenomenon in Candida glabrata, our Class 3 adaptors displayed equal tolerance to both caspofungin and micafungin. Collectively, these findings demonstrate that, in a clade III clinical isolate of C. auris under the tested laboratory conditions, laboratory exposure to an agricultural triazole can rapidly select for clinically relevant azole cross-resistance and echinocandin tolerance in C. auris, suggesting that environmental fungicide use may inadvertently compromise the efficacy of last-line antifungals."

Pronounced drug resistance makes treatment failure common, and so does antifungal tolerance, a phenomenon enabling pathogen survival at supra-MIC concentrations without resistance mutations. Here, we uncover a mechanism of antifungal tolerance in C. auris engaging the mitochondrial cytochrome bc1 complex. Deletion of RIP1, a conserved catalytic complex subunit, does not significantly alter the susceptibility to caspofungin or voriconazole. However, rip1\u0394 mutants exhibit a marked reduction in antifungal tolerance across a wide range of supra-MIC concentrations. Transcriptomics reveals the dysregulation of multiple drug resistance and tolerance-related genes in the rip1\u0394 mutant, demonstrating a role for Rip1 in controlling antifungal susceptibility. Targeting cytochrome bc1 function with the fungal-specific inhibitor Inz-5 enhances antifungal action of both voriconazole and caspofungin. Additionally, ablation of RIP1 causes fitness defects, suggesting that cytochrome bc1 is a potential antifungal target against C. auris infections."

In this study, we report the synthesis, characterization, and biological evaluation of a guar gum-quercetin bioconjugate designed to improve the practical applicability of quercetin through covalent conjugation with a biocompatible polysaccharide scaffold and a cystamine-based disulfide linker. The formation of the GG-Cys-Quer conjugate was supported by FTIR, 1H/13C NMR, CHNS elemental analysis, degree-of-substitution estimation, SEM, and TGA. The conjugate showed potent antifungal activity against five clinical C. auris isolates, with MIC and MFC values ranging from 0.030 to 0.245 \u00b5g mL-1 and 0.123 to 0.488 \u00b5g mL-1, respectively. Against the resistant isolate MRL6057, GG-Cys-Quer showed an MIC of 0.245 \u00b5g mL-1, whereas caspofungin showed an MIC of 4.0 \u00b5g mL-1 under the same assay conditions. Mechanistic studies showed increased intracellular ROS accumulation, loss of mitochondrial membrane potential, and apoptosis-associated changes, as confirmed by Annexin V/PI staining, with a concentration-dependent increase in late apoptotic/necrotic cell populations at higher exposure levels. Ultrastructural analysis further revealed membrane deformation, pore formation, and cellular collapse, supporting severe fungal cell damage following treatment. In mammalian L929 fibroblasts, GG-Cys-Quer maintained >85% cell viability at MFC-level exposure, indicating preliminary in vitro cytocompatibility. Overall, these findings demonstrate that GG-Cys-Quer is a structurally characterized guar gum-quercetin conjugate with strong in vitro antifungal activity against C. auris and a mechanism involving oxidative stress, mitochondrial dysfunction, and apoptosis-associated fungal cell death.

In this study, three clinical C. auris strains (namely C. auris strain 01, C. auris strain 03, and C. auris strain 13) with distinct origins were characterized to investigate their phenotypic variations and mechanisms of azole resistance. Comprehensive profiling revealed significant inter-strain differences in biofilm formation, cell surface hydrophobicity, adhesion capacity, and phospholipase activity. Testing for antifungal susceptibility showed that the three clinical strains exhibited different minimum inhibitory concentrations for multiple azoles (fluconazole, voriconazole, and itraconazole) and echinocandins (anidulafungin and micafungin). Sequencing identified Y132F mutations in the ERG11 gene of the three clinical strains. Mechanistic investigations demonstrated that fluconazole exposure significantly upregulated the expression of efflux pump genes (CDR1 and CDR2) and the genes encoding their transcriptional regulators (MDR1 and TAC1b). In a murine skin colonization model, comparing data from the standard strain C. auris strain CBS12766 and clinical strains of C. auris strain 03 and C. auris strain 13 exhibited a significantly higher fungal burden of tissue, whereas strain C. auris strain 01 showed an intermediate level. Host immunity response analysis revealed that expression of the IL-1\u03b2 gene was significantly elevated in C. auris strain CBS12766-infected mice, while expression of IL-6 and CXCL-1 genes was predominantly increased in the C. auris strain 01, with TNF-\u03b1 gene expression levels being comparable across all strains. Histopathological examination confirmed local infiltration of inflammatory cells and mild epidermal edema, indicating active host immune engagement. Overall, our findings highlighted substantial phenotypic heterogeneity, different colonization capacities, and differences in expression of inflammatory cytokines among the C. auris strains.

While point mutations underlying antifungal resistance are well characterised, the contribution of structural genomic variation to antifungal responses remains poorly defined. Here, we integrate whole-genome sequencing, a genome-wide copy number variation (CNV) screen, electrophoretic karyotyping, and mutation-accumulation analyses to investigate the role of structural variation in antifungal susceptibility across a clinical cohort of C. auris isolates. We identify recurrent CNV hotspots, with segmental duplications representing a predominant mode of genome variation. Small duplications encompassing ERG11 arise at high frequency and frequently co-occur with drug resistance-associated ERG11 mutations, collectively enhancing azole resistance. In addition, large centromere-inclusive duplications of chromosome 1 generate supernumerary chromosomes, leading to paradoxical growth and reduced susceptibility to caspofungin, an echinocandin. At the population level, structural variants frequently arise in parallel to FKS1 mutations, suggesting multiple genetic mechanisms underlying reduced drug susceptibility. Together, our findings establish segmental duplication as a major, non-mutational driver of antifungal resistance, highlighting the need to consider structural genomic variation in both resistance surveillance and clinical susceptibility testing."

Human immunity to C. albicans infection is thought to be largely dependent on neutrophil reactive oxygen and nitrogen species (ROS/RNS) generation by neutrophils. Despite this, our understanding of innate immune killing and escape by C. albicans is primarily studied in macrophages, and the precise mechanisms of evasion are unclear in neutrophils. Here, we sought to determine the importance of neutrophil reactive nitrogen species (RNS) production during C. albicans infection in vivo. Using a zebrafish model, we found that C. albicans rapidly downregulated neutrophil RNS below basal levels during the first day post-infection, a time at which neutrophil RNS is upregulated in bacterial infections as an important host-defense mechanism, indicating fungal evasion of host neutrophils. We confirmed the downregulation of RNS in human primary neutrophils and with clinical Candida isolates, including emerging human pathogens Candida auris and Candida glabrata. Inducible nitric oxide synthase (iNOS; Nos2 in zebrafish), the enzyme responsible for RNS production, competes with the arginase enzyme for a shared substrate, L-arginine. Using a zebrafish arginase2 transgenic line and a C. albicans car1\u0394 mutant, we showed that both host and fungal arginase contribute to the reduction in neutrophil RNS. Despite pathogen downregulation, upregulation of neutrophil RNS via hypoxia-inducible factor 1\u03b1 (Hif-1\u03b1) stabilization was sufficient to improve host survival following C. albicans infection. Inhibition of Nos2 blocked the host protective effect of Hif-1\u03b1 stabilization. Finally, restoration of neutrophil RNS via Hif-1\u03b1 stabilization was additive to clinically relevant antifungal treatment, increasing survival and clearance of C. albicans infections. Together, these data demonstrate that restoration of the neutrophil RNS response in C. albicans infection improves infection outcomes, highlighting the potential of targeting Hif-1\u03b1 and RNS in host-directed therapies against fungal infections.IMPORTANCECandida albicans is a fungus that normally lives harmlessly in the human body but can cause life-threatening infections in people with weakened immune systems. A key part of the body's defense against this fungus is neutrophils, immune cells that kill microbes using toxic molecules. However, how Candida avoids neutrophil defense is not well understood. Here, we used zebrafish and human immune cells to show that Candida suppresses an important neutrophil defense, reactive nitrogen species (RNS), during infection. Unlike bacteria, which trigger RNS, Candida reduces these protective molecules to below normal levels, helping its survival. This effect was also observed with other disease-causing Candida species. We went on to show that both the host and Candida contribute to this suppression. Importantly, boosting the neutrophil response improved survival and helped clear infection, especially when combined with standard antifungal drugs. These findings suggest new ways to support the immune system alongside existing treatments."

In this study, we demonstrated that the Neosartorya (Aspergillus) fischeri antifungal protein NFAP2 selectively targets early morphogenetic states of Candida albicans and Candidozyma auris, revealing a transient window of susceptibility during filament and pseudohypha formation. Integrated transcriptomic and in vivo analyses indicate that these developmental states may represent context-dependent entry points for NFAP2 activity. In C. albicans, transcriptomic and network analyses indicate the presence of an anabolic, translation-associated gene expression signature, accompanied by suppression of stress-protective pathways, which is associated with increased susceptibility of emerging hyphae to NFAP2 but does not establish a direct causal mechanism. In C. auris, increased susceptibility of pseudohyphal cells occurred without overt transcriptional remodeling, consistent with the characteristically muted gene expression responses of this species, suggesting that NFAP2 sensitivity is governed primarily by biophysical and post-transcriptional mechanisms rather than transcriptional reprogramming. Importantly, morphotype-specific vulnerabilities observed in vitro were reflected in distinct in vivo outcomes in Galleria mellonella, as NFAP2 was well tolerated and provided a moderate, transient survival benefit in pseudohyphal C. auris infections, but not in filamentous C. albicans, where a worsened outcome was observed, consistent with species- and morphotype-dependent activity. Taken together, these results suggest that early morphogenetic states of Candida are stress-sensitive phenotypes associated with increased susceptibility to NFAP2. This work provides a proof-of-concept framework for future investigation of morphotype-associated antifungal vulnerability to peptide-based antifungal strategies.IMPORTANCEDrug-resistant Candida species represent an escalating global health threat; however, most antifungal strategies continue to target fungal growth rather than intrinsic biological vulnerabilities. In this study, we identified early morphogenetic transitions as a shared window of increased susceptibility in both Candida albicans and the highly drug-resistant pathogen Candidozyma (formerly Candida) auris. By integrating transcriptomic profiling with in vivo infection models, we found that NFAP2 exhibits antifungal activity that is influenced by these transient developmental states in a context-dependent manner while remaining well tolerated by the host. We further demonstrated that morphotype-specific stress responses are associated with the divergent sensitivities of C. albicans and C. auris to NFAP2. These results support the concept that fungal morphogenesis may represent a therapeutically actionable process and provide a framework for designing antifungal strategies that target developmental states rather than growth. This strategy may open new opportunities for improving protein- and peptide-based therapies, as well as combination therapies against difficult-to-treat fungal pathogens."

However, the molecular mechanisms underlying its virulence remain incompletely understood. In this study, we performed in vivo transcriptome analysis using an immunosuppressed mouse gastrointestinal infection model to identify genes associated with host adaptation and virulence during infection. By comparing fungal transcriptomes obtained from colonization and dissemination sites with those from\u00a0in vitro cultures, we identified genes that were consistently upregulated during infection. Among these genes, the unfolded protein response regulator HAC1 was selected as a candidate virulence-associated gene for further analysis. Reverse transcription PCR and sequencing analyses revealed that\u00a0HAC1 mRNA in C. auris undergoes an unconventional splicing event of 287 bp that is enhanced under endoplasmic reticulum stress conditions. The excised region spans the annotated open reading frame boundary, suggesting that the translated region of\u00a0HAC1 may require re-evaluation. Notably, a proportion of HAC1 transcripts appeared to be spliced even under non-stress conditions, indicating a detectable basal level of the unfolded protein response. Differences in splicing dynamics were also observed among clade strains. Functional analyses demonstrated that deletion of\u00a0HAC1 increased sensitivity to endoplasmic reticulum stress. The HAC1 deletion mutant also exhibited reduced virulence in both Galleria mellonella and immunosuppressed mouse infection models, as evidenced by delayed host mortality and decreased fungal burdens, respectively. These findings indicate that HAC1 contributes to endoplasmic reticulum stress adaptation and survival in the host environment and identify\u00a0HAC1 as a virulence-associated gene in C. auris. Candida auris is an emerging multidrug-resistant fungal pathogen.

In this study, we employed a targeted drug-repurposing strategy to identify novel indications for existing FDA-approved compounds against C. auris, leading to the identification of Tavaborole as a potent fungistatic agent. Tavaborole displayed robust activity across all five tested clades of C. auris, as well as against Candida albicans and Candida glabrata. To investigate drug resistance mechanisms of C. auris, we applied quantitative proteomics analyses following exposure to Tavaborole and Amphotericin B (AmB), complemented by electron microscopy. Proteomic profiling revealed that C. auris mounts distinct but overlapping adaptive responses to antifungal stress, involving stress response pathways, metabolic reprogramming and amino acid biosynthesis. While Tavaborole primarily induced targeted stress adaptation, AmB triggered a broader, multi-pronged resistance response including oxidative stress mitigation, osmolyte production and metabolic remodeling. Shared alterations in glycogen metabolism and amino acid biosynthesis suggest conserved antifungal adaptation mechanisms. Altogether, this study highlights Tavaborole as a promising antifungal candidate against C. auris, sheds novel insights into drug resistance mechanisms employed by the pathogen and delivers a drug-repurposing procedure highly customizable to target other microorganisms."

Its high environmental persistence, immune evasion, phenotypic heterogeneity, and multidrug resistance are major contributors to its high mortality rate. Under diverse environmental conditions, C. auris exhibits marked phenotypic plasticity, switching from non-aggregative to aggregative form and, in some contexts, pseudohyphal-like morphotypes. However, the significance of this heterogeneity in pathogenesis and drug tolerance remains poorly understood. This review provides a comprehensive overview of how external cues influence C. auris morphotypes, with particular emphasis on aggregation. It further highlights the role of adhesion-associated genes (ALS4112 and SCF1) in mediating cell aggregation and examines their evolutionary trajectories across Candida species and among distinct C. auris clades. In addition, we discuss emerging molecular mechanisms that may underlie differential morphotypes and their links to virulence and antifungal tolerance. Evidence suggests that mannan-mediated masking of pathogen-associated molecular patterns (PAMPs) in the aggregative phenotype may contribute to persistence and reduced virulence in the host. Overall, C. auris can remodel its cell wall and elicit distinct host immune responses based on its form, opening avenues for novel therapeutic strategies which further require deeper experimental validation."

In glucose-starved macrophages, NINJ1 ruptures membranes independently of known cell death programs. Consistently, NINJ1 is the dominant effector of fungal-induced macrophage damage amongst host cell death factors. Supplementation of the amino acid alanine rescues glucose-starved macrophages better than glucose, and it does so by inhibiting NINJ1 oligomerization.

Its rapid global expansion and resistance to multiple antifungal classes pose major challenges to treatment and containment. Extracellular vesicles (EVs) have recently been recognized as important mediators of fungal communication, virulence, and stress adaptation. Here, we examine how caspofungin, a frontline echinocandin, reshapes the EV metabolome of C. auris. Caspofungin exposure drives pronounced remodeling of EV size distributions, yielding a predominance of smaller, more uniform EVs alongside a minor population of larger subtypes. Metabolomic profiling of EVs revealed marked enrichment of metabolites involved in nucleotide salvage and recycling, along with altered amino acid abundances, including increases in amino acids associated with stress responses and redox regulation. These changes are consistent with altered nucleotide turnover and amino acid metabolism under antifungal stress. Importantly, these metabolic alterations reflect caspofungin-induced changes in cellular metabolism that are selectively exported via extracellular vesicles, rather than metabolic activity occurring within the vesicles themselves. Export of these metabolites via EVs may support population-level coordination, biofilm remodeling, and modulation of host immune responses, contributing to echinocandin tolerance. Together, our findings highlight nucleotide- and amino acid-associated metabolic features of EVs as informative readouts of caspofungin exposure and highlight the EV metabolome as a promising source of non-invasive biomarkers for monitoring drug exposure and resistance.

Here, we performed a comprehensive inventory and functional analysis of the HGT family in C. auris to assess its contribution to antifungal import.

Despite the recent emergence of at least four distinct clades at the global scale, little remains known about how C. auris is so adept at growing on skin and the key genes and pathways it utilizes to metabolize the scarce nutrients available. Here, we identify the roles that conventional and alternative carbon metabolism genes and metabolic pathways have in facilitating C. auris growth through laboratory-based experiments and bioinformatics analyses. In artificial skin-like media, all four clades of C. auris were more capable of growing than Candida albicans SC5314, a clinically relevant counterpart. By investigating the differential regulation of C. auris when growing in skin-like media as compared to rich fungal media, we uncovered hundreds of genes in multiple metabolic pathways. To further test the mechanisms of these metabolic pathways, we deleted several non-essential gene candidates including FOX2 (B9J08_002847), CAT2 (B9J08_000010), and ICL1 (B9J08_003374). The mutant strains all exhibited abrogated growth in skin-like media and demonstrated nutrient preferences that differed from the wild type.

Candida auris is an emerging fungal pathogen with human skin as its primary site of colonization and subsequent transmission. Here, we show the importance of conventional and alternative carbon metabolism for the ability of C. auris to grow in artificial skin-like media. This knowledge provides a better understanding of C. auris metabolism and sheds light on genes and pathways that could be targeted to interfere with persistent skin colonization."

We also detect previously unreported subclades and resistance mutations, including FKS1 Phe635Leu and co-occurring ERG11/FKS1 variants in wastewater samples up to nearly five months before their appearance in clinical settings. Transcriptomic profiling of drug-resistant isolates under antifungal and stress conditions identifies previously uncharacterized adaptation mechanisms, including differential regulation of ribosomal assembly pathways and cell cycle checkpoints. These findings highlight how wastewater intelligence can enhance traditional public\u00a0health approaches for early detection and monitoring of C. auris outbreaks and antifungal resistance."

Phenotypically, the pathogen displays significant clade-dependent diversity, including variable biofilm formation, aggregation, and skin colonization capabilities.\n\n### [ABSTRACT & REWRITTEN CLAIM]\n*Candida auris* acts as a high-priority, multidrug-resistant fungal pathogen with complex regulatory mechanisms. Research identifies the importance of ergosterol biosynthesis, efflux pump activity (e.g., CDR1, MDR1), and mitochondrial adaptation (e.g., cytochrome bc1) in maintaining viability under antifungal pressure. Morphological plasticity, specifically the ability to transition between yeast, aggregative, and pseudohyphal forms, serves as a mechanism for immune evasion and environmental persistence.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe pathogenic profile of *Candida auris* is defined by its evolutionary divergence into distinct clades, each exhibiting unique molecular signatures and virulence traits. Its resistance to conventional antifungals\u2014including azoles, polyenes, and echinocandins\u2014is driven by both canonical point mutations (e.g., *ERG11* and *FKS1* mutations) and structural genomic variations such as segmental duplications. The ability of *C. auris* to persist in hospital settings is linked to its robust biofilm-forming capacity, regulated by transcription factors such as *WOR2*, and its unique skin-tropic behavior supported by specific carbon metabolism pathways and carbonic anhydrase activity. Host interaction is mediated by the suppression of neutrophil reactive nitrogen species and the exploitation of glucose-starvation-induced cell damage.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   The transcription factor *WOR2* acts as a negative regulator of biofilm formation; its inactivation is observed in clinical strains to enhance persistence.\n*   *Candida auris* suppresses host innate immune defenses by downregulating neutrophil reactive nitrogen species to below basal levels.\n*   The carbonic anhydrase *Nce103* is essential for maintaining fitness in nutrient-limited environments and sustaining amphotericin B resistance.\n*   Segmental duplications, rather than just point mutations, serve as a predominant, non-mutational driver of multidrug resistance.\n*   Extracellular vesicles (EVs) export metabolites linked to nucleotide salvage and amino acid metabolism, serving as a mechanism for population-level stress adaptation.\n*   *C. auris* exhibits \"morphotype-specific vulnerabilities,\" where transient developmental states (filamentous or pseudohyphal) represent entry points for peptide-based therapies.\n*   Nutrient limitation in the host environment triggers *NINJ1*-dependent macrophage lysis, facilitating fungal escape.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

NT-a9 is a novel triazole antifungal with potent activity against Candida and Cryptococcus species via strong inhibition of ergosterol biosynthesis. In vitro, NT-a9 exhibited potent and sustained antifungal activity against clinical isolates, with superior potency compared to fluconazole (FLC). It also displayed a prolonged post-antifungal effect (PAFE) against most Candida species, a property rarely seen in conventional azoles. Resistance profiling demonstrated that NT-a9 possesses a high genetic barrier, fully suppressing resistant mutant emergence in Cryptococcus species and maintaining stable susceptibility in Candida albicans during 28 days of continuous exposure. NT-a9 retained potent activity against FLC-resistant Cryptococcus neoformans and multidrug-resistant Candida auris, with minimal influence from drug efflux mechanisms. In murine invasive candidiasis, a single low dose of NT-a9 achieved 100% survival and markedly reduced renal fungal burden, significantly outperforming FLC. NT-a9 also substantially improved survival in mice infected with FLC-resistant C. auris. Mechanistically, NT-a9 binds Erg11 with much higher affinity than FLC by forming key hydrogen bonds with Gly307 and His377, leading to irreversible ergosterol depletion, toxic sterol accumulation, and severe fungal membrane damage. Transcriptomic analysis further confirmed that NT-a9 extensively disrupts sterol biosynthesis and triggers compensatory gene expression that reinforces its antifungal action. As a novel triazole integrating long-lasting efficacy, a high resistance barrier, and potent activity against pan-azole-resistant pathogens, NT-a9 represents a promising clinical candidate for treating IFIs.\n\nID: 42549922\nTitle: Baicalein suppresses adhesion and biofilm formation in Candida auris.\nAbstract: Candida auris, an emerging multidrug-resistant fungal pathogen, poses a severe global public health threat owing to its high nosocomial transmissibility, considerable mortality, and widespread antifungal resistance. Baicalein (BE), a major bioactive constituent of Scutellaria baicalensis Georgi, exhibits notable antifungal potential, yet its specific molecular mechanisms against C. auris remain poorly elucidated. In this study, we determined the antifungal activity of BE against multiple C. auris isolates, assessed its effects on fungal growth, virulence attributes, adhesion, and biofilm development, validated its in vivo protective efficacy in a Galleria mellonella infection model, and explored the underlying mechanisms via transcriptomic sequencing. BE exerted potent and consistent antifungal activity against all tested strains, with a minimum inhibitory concentration of 1 \u03bcg/mL, minimum fungicidal concentrations of 4-8 \u03bcg/mL, and a sessile minimum inhibitory concentration of 32 \u03bcg/mL. It time- and concentration-dependently suppressed fungal growth, virulence factor expression, adhesion to biological and non-biological surfaces, and biofilm formation, while conferring significant in vivo protection against C. auris infection. Transcriptomic analysis identified 11 adhesion- and biofilm-associated target genes, among which SCF1 and ALS1 served as pivotal regulators. Collectively, BE exerts robust anti-C. auris effects by modulating key target gene expression to interfere with multiple virulence-related processes, providing experimental support for its development as a novel antifungal agent for C. auris infection treatment.IMPORTANCEThe emerging multidrug-resistant fungal pathogen Candida auris has become a critical global public health concern. Its pronounced nosocomial transmissibility, high infection-associated mortality, and extensive cross-resistance to mainstream antifungal agents have created substantial unmet needs in clinical treatment and nosocomial infection control. In this study, we systematically validated the in vitro and in vivo antifungal activity of baicalein against C. auris and elucidated the molecular mechanism underlying its modulation of virulence-related genes. Our findings provide a pivotal experimental basis for the development of novel antifungal therapeutics targeting C. auris infections.\n\nID: 42548967\nTitle: Qdr3 Coordinates cellular homeostasis, mitochondrial remodeling, and virulence in Candidozyma auris (Candida auris).\nAbstract: Qdr3 acts as a global regulator in Candidozyma auris (Candida auris), coordinating mitochondrial function and cell-surface architecture.

Here, we investigated whether laboratory exposure of a clade III clinical C. auris isolate to TCZ could induce cross-resistance to clinical antifungals. Among 17 agrochemicals tested, only TCZ exhibited intrinsic antifungal activity. Brief (48 h) exposure to sub-MIC TCZ (1 \u03bcg/mL) selected variants (6.9% frequency) with cross-resistance to TCZ and fluconazole, but full susceptibility to caspofungin. Exposure to supra-MIC TCZ (8-32 \u03bcg/mL) produced three phenotypic classes: Class 2 (TCZ-R, fluconazole-R) and Class 3 (TCZ-R, fluconazole-R, plus tolerance to caspofungin and micafungin). The frequency of Class 3 increased dose-dependently from 23% to 50% as TCZ concentration rose. RNA-Seq revealed that both classes overexpressed MDR1, TAC1b, UPC2 and FKS1, but Class 2 showed broad ergosterol pathway upregulation, whereas Class 3 exhibited restricted ergosterol activation but downregulation of the sole chitinase gene CHT1 (5.17-fold), a known mechanism of echinocandin tolerance. Unlike the CRS-MIS phenomenon in Candida glabrata, our Class 3 adaptors displayed equal tolerance to both caspofungin and micafungin. Collectively, these findings demonstrate that, in a clade III clinical isolate of C. auris under the tested laboratory conditions, laboratory exposure to an agricultural triazole can rapidly select for clinically relevant azole cross-resistance and echinocandin tolerance in C. auris, suggesting that environmental fungicide use may inadvertently compromise the efficacy of last-line antifungals.\n\nID: 42545748\nTitle: Candida auris: An opportunistic fungal pathogen and a priority emergent threat.\nAbstract: Candida auris is an opportunistic yeast causing infections in vulnerable patients leading to high mortality ratio. The Centers for Disease Control and Prevention (CDC) has designated it as a pathogen of concern. The World Health Organization (WHO) has listed it in priority list of fungal pathogens. C.\u00a0auris has the ability to spread very fast inside the hospital environment and cause outbreaks worldwide. It has a very high affinity toward skin colonization, especially in the areas like axilla and groin. Based on whole genome sequencing it is classified into five clades. Each clade has different geographical distribution. Often C. auris gets misidentified as other species due to its phylogenetic similarity with C.\u00a0heamulonii. This can only be resolved by establishing diagnosis at molecular levels. Whole genome sequencing and polymerase chain reaction are some of the important molecular diagnostic methods for detection of C. auris. MALDI-TOF-MS is a culture based highly efficient method that is widely being used for C. auris identification. Treatment of C. auris infection depends on effective antifungal therapy, as multidrug resistance is quite common, the drug regime is decided after antifungal sensitivity testing. It is commonly treated with echinocandins and polyenes. Apart from the antifungal therapy it is also important to monitor the fungemia by performing blood cultures. A strict surveillance system can help prevent the disease. Timely screening of hospital personnel carrying the yeast can contain the spread of this organism. Newer antifungal agents are also required as the organism develops resistance very fast.\n\nID: 42541938\nTitle: The potential of bacteriocins in invasive fungal infections: Antifungal activities and intestinal protection.\nAbstract: Invasive fungal infections are life-threatening complications in immunocompromised and critically ill patients. Invasive candidiasis may arise from endogenous fungal reservoirs, particularly under conditions of intestinal barrier disruption. Although conventional antifungal agents remain the therapeutic foundation, their clinical use is increasingly challenged by the emergence of resistant fungal pathogens, such as Candida auris. Bacteriocins are ribosomally synthesized antimicrobial peptides produced by microorganisms. Beyond their well-established applications in the food industry, bacteriocins have attracted increasing attention in recent years for their antifungal properties. In this review, we provide an overview of bacteriocins with reported antifungal activity and summarize their underlying mechanisms. In addition, we discuss the potential protective effects of bacteriocins on the microbial, mechanical, chemical, and immune barriers of the intestine. Finally, we evaluate the potential clinical applications of these bacteriocins, along with future challenges and research directions related to invasive fungal infections.\n\nID: 42537628\nTitle: Pathogenicity and virulence of Candida auris.\nAbstract: Candida auris (Candidozyma auris) has emerged as a multidrug\u2011resistant human fungal pathogen that causes infections of high morbidity and mortality. Notably, it exhibits a unique ability to grow and persist on human skin, thus leading to efficient transmission through skin-to-skin contact. As a result, C. auris poses a significant risk of outbreaks in healthcare settings, especially in nursing homes that care for elderly patients. Most concerning, C. auris clinical isolates demonstrate widespread and, in some cases, untreatable resistance to all antifungal drug classes, including azoles, polyenes (amphotericin B), and echinocandins. Consequently, invasive C. auris infections cause high mortality rates (30-60%) even with antifungal therapy. Here, we provide a comprehensive overview of candidiasis caused by C. auris, discussing both host and pathogen determinants of skin colonization, as well as key challenges associated with preventing dissemination and management of disseminated fungal infections.\n\nID: 42534992\nTitle: Hospital-acquired Candidozyma auris infections as an emerging threat in Saudi Arabia and Egypt: A narrative review on epidemiology and prevention strategies.\nAbstract: Candidozyma auris (C. auris) is an emerging multidrug-resistant pathogen increasingly associated in hospital-associated outbreaks, particularly in intensive care units (ICUs), and is classified by the World Health Organization as a critical priority pathogen. Its ability to persist in hospital environments, colonize patients asymptomatically, and exhibit multi-drug resistance to antifungal drugs poses a major challenge to infection prevention and control (IPC). This work is a synthesis of published, hospital-based evidence on nosocomial C. auris infections in Saudi Arabia and Egypt, with implications for antifungal stewardship, infection prevention, and control. Saudi Arabia and Egypt were selected because of their contrasting surveillance, healthcare capacities, and reporting intensities, which allow for comparative regional interpretation. This narrative review was conducted using PubMed and Google Scholar for English-language articles from 2020 to 2025, with key terms including \"Candida auris,\" \"C. auris,\" together with related concepts such as epidemiology, transmission, IPC, Saudi Arabia, Egypt, and drug resistance, with an emphasis on hospital-based studies. Available evidence indicates a marked increase in reported cases and outbreaks in Saudi Arabia, with risk factors of ICU exposure, invasive medical device use, and antibiotic use, whereas data from Egypt though limited increasingly suggest misdiagnosis and emerging local circulation in tertiary care settings. Both countries exhibit high fluconazole resistance and variable susceptibility to amphotericin B, with echinocandins as the preferred first-line therapy. These findings highlight the urgent need for enhanced surveillance, improved diagnostic capacity, and sustained, consistent IPC strategies in healthcare settings across the regions to limit further spread of C. auris.\n\nID: 42532402\nTitle: Candidemia in Post-COVID Era: Increasing incidence of endemic fluconazole-resistant Candida parapsilosis and Candidozyma auris.\nAbstract: To assess the effect of the COVID-19 pandemic on the epidemiology of candidemia. We retrospectively analyzed candidemia episodes diagnosed from 2018 to 2024 in a tertiary university hospital, evaluating incidence trends, species distribution, ward origin, antifungal susceptibility, and antifungal consumption in the context of the COVID-19 pandemic. Candidemia incidence remained high beyond the COVID-19 pandemic, particularly in intensive care unit. Candida parapsilosis species complex was the predominant pathogen, accounting for 41.4% in the post-COVID era, and exhibited persistently high fluconazole resistance rates of up to 64.3% together with increasing resistance to voriconazole. Increased azole resistance was associated with isolation from intensive care units. Candidozyma auris (Candida auris), first identified in 2022, rapidly became endemic, accounting for 29.5% of isolates in the post-COVID era and exhibiting uniform resistance to fluconazole. Candida albicans (18.5%) ranked as the third most frequently isolated species. Amphotericin B and echinocandins retained excellent in vitro activity, whereas the clinical utility of fluconazole was markedly reduced due to the high prevalence of resistant C. parapsilosis and C. auris. The COVID-19 pandemic was associated with a sustained increase in candidemia incidence, major shifts in species distribution, and high fluconazole resistance rates. These findings underline the need for ongoing surveillance and implementation of infection control measures.\n\nID: 42530613\nTitle: Cytochrome bc1 Catalytic Subunit Rip1 Modulates Antifungal Tolerance in Candida auris.\nAbstract: Candida auris is an emerging fungal pathogen causing invasive infections in immunocompromised patients, with mortality rates reaching up to 60%. Pronounced drug resistance makes treatment failure common, and so does antifungal tolerance, a phenomenon enabling pathogen survival at supra-MIC concentrations without resistance mutations. Here, we uncover a mechanism of antifungal tolerance in C. auris engaging the mitochondrial cytochrome bc1 complex. Deletion of RIP1, a conserved catalytic complex subunit, does not significantly alter the susceptibility to caspofungin or voriconazole. However, rip1\u0394 mutants exhibit a marked reduction in antifungal tolerance across a wide range of supra-MIC concentrations. Transcriptomics reveals the dysregulation of multiple drug resistance and tolerance-related genes in the rip1\u0394 mutant, demonstrating a role for Rip1 in controlling antifungal susceptibility. Targeting cytochrome bc1 function with the fungal-specific inhibitor Inz-5 enhances antifungal action of both voriconazole and caspofungin. Additionally, ablation of RIP1 causes fitness defects, suggesting that cytochrome bc1 is a potential antifungal target against C. auris infections.\n\nID: 42527656\nTitle: The urgent and challenging superbug fungus Candidozyma auris (formerly Candida auris): a comprehensive review.\nAbstract: Based on recent literature, this review critically summarises current information on Candidozyma auris (formerly known as Candida auris) infections to identify factors contributing to their emergence and persistence in healthcare settings. Specifically, it seeks to identify major gaps and challenges in Candidozyma auris (C. auris) classification, diagnostic methods, virulence traits, antifungal therapy, and infection prevention, thereby providing a consolidated evidence base to support improved clinical management, surveillance, and future research. Recent advances have enabled rapid, accurate identification of C. auris using updated MALDI-TOF MS databases and real-time PCR assays. Novel antifungal agents and combination therapies offer potential options against resistant and biofilm-forming C. auris, while recent studies of aggregation, biofilm formation and adhesion, and phenotypic switching have provided new insights into its virulence and persistence in healthcare settings. C. auris exhibits many virulence traits that influence the severity of its infections. Identifying C. auris using conventional microbiological and culture-based methods can be challenging, often leading to delayed diagnoses and inappropriate treatment\u00a0of infections. Its resistance to commonly used antifungal drugs, including azoles, polyenes and echinocandins, further complicates infection control and treatment strategies. C. auris strains are classified into six distinct clades: South Asia, East Asia, South Africa, South America, Iran and Singapore. Each clade exhibits unique genetic characteristics and varying levels of drug resistance. The emergence of C. auris underscores the high priority and urgent need for research, the development of practical molecular-based diagnostic tools, novel antifungal therapies, and robust infection control measures to combat this growing threat.\n\nID: 42522315\nTitle: Phytochemicals as Novel Antifungal Agents Against Candida species.\nAbstract: Infections caused by Candida, including vulvovaginal candidiasis (VVC) and invasive candidiasis (IC), are a growing public health problem, exacerbated by multidrug resistance, biofilm persistence, and the limited development of antifungal drugs. In this review, we discuss plant-derived natural products with potent anti-Candida activity, specifically terpenoids, alkaloids, flavonoids, phenolics, and their nanoformulations. Many compounds, including berberine, artemisinin, thymol, eugenol, carvacrol, quercetin, catechins, lawsone, and caffeic acid, have shown the ability to modulate the fundamental mechanisms of fungal growth, which include disrupting membranes, inhibiting ergosterol biosynthesis, modulating efflux pumps, inducing oxidative stress, and biofilm inhibition. Some phytochemicals also demonstrate synergism with azoles, polyenes, and echinocandins, which can support dose reduction and restoration of resistance. Ultimately, while there is supportive preclinical evidence for anti-Candida action via the aforementioned compounds, clinical translation has been limited due to issues concerning standardization of use, pharmacokinetic variability, and toxicity issues. Some recent advances in nano-delivery systems, structural bioactivity modifications, and molecular docking studies provide a path forward when considering ways to maximize antifungal properties and improve bioavailability. This review highlights current advancements, therapeutic opportunities, and critical research gaps to accelerate the integration of phytochemicals into antifungal stewardship and device-associated infection control strategies.\n\nID: 42519068\nTitle: Guar gum-quercetin bioconjugate as a promising multifunctional biomaterial for combating drug-resistant fungal pathogens.\nAbstract: The global emergence of Candida auris, a multidrug-resistant fungal pathogen associated with high transmissibility and limited therapeutic options, highlights the need for new antifungal strategies. In this study, we report the synthesis, characterization, and biological evaluation of a guar gum-quercetin bioconjugate designed to improve the practical applicability of quercetin through covalent conjugation with a biocompatible polysaccharide scaffold and a cystamine-based disulfide linker. The formation of the GG-Cys-Quer conjugate was supported by FTIR, 1H/13C NMR, CHNS elemental analysis, degree-of-substitution estimation, SEM, and TGA. The conjugate showed potent antifungal activity against five clinical C. auris isolates, with MIC and MFC values ranging from 0.030 to 0.245 \u00b5g mL-1 and 0.123 to 0.488 \u00b5g mL-1, respectively. Against the resistant isolate MRL6057, GG-Cys-Quer showed an MIC of 0.245 \u00b5g mL-1, whereas caspofungin showed an MIC of 4.0 \u00b5g mL-1 under the same assay conditions. Mechanistic studies showed increased intracellular ROS accumulation, loss of mitochondrial membrane potential, and apoptosis-associated changes, as confirmed by Annexin V/PI staining, with a concentration-dependent increase in late apoptotic/necrotic cell populations at higher exposure levels. Ultrastructural analysis further revealed membrane deformation, pore formation, and cellular collapse, supporting severe fungal cell damage following treatment. In mammalian L929 fibroblasts, GG-Cys-Quer maintained >85% cell viability at MFC-level exposure, indicating preliminary in vitro cytocompatibility. Overall, these findings demonstrate that GG-Cys-Quer is a structurally characterized guar gum-quercetin conjugate with strong in vitro antifungal activity against C. auris and a mechanism involving oxidative stress, mitochondrial dysfunction, and apoptosis-associated fungal cell death. Further side-by-side studies with free quercetin, linker controls, guar gum controls, and in vivo models are required to define the specific contribution of conjugation and assess translational potential.\n\nID: 42515783\nTitle: Bioactive Silver Nanoparticles Synthesized Using Endophytic Bacillus subtilis CG1 and Their Antimicrobial and Antibiofilm Potential Against Drug-Resistant Pathogens.\nAbstract: Background/Objectives: The study addresses the global health challenge posed by multidrug-resistant (MDR) pathogens, highlighting the urgent need for alternative antimicrobial solutions. This study investigated the in vitro antimicrobial and antibiofilm potential of endophytic mediated-synthesized silver nanoparticles (AgNPs). Methods: An endophytic bacterium was isolated from the medicinal plant Commiphora gileadensis in Saudi Arabia and identified as Bacillus subtilis CG1 through 16S rRNA gene sequencing. The bacterium was utilized for the green synthesis of AgNPs, as confirmed by Ultraviolet-visible (UV-Vis) spectroscopy. AgNPs characterization was done using Fourier-transform infrared (FTIR) spectroscopy, Transmission and scanning electron microscopy (TEM and SEM), energy-dispersive X-ray spectroscopy (EDX), and dynamic light scattering (DLS). The antimicrobial efficacy of the fabricated AgNPs was tested against eight clinically relevant pathogens using standard in vitro assays such as the agar disk diffusion method, minimum inhibitory concentration (MIC), minimum bactericidal and fungicidal concentrations (MBC and MFC). Additionally, AgNPs were tested for antibiofilm activity against P. aeruginosa and S. epidermidis. Tested pathogens included Methicillin-Resistant Staphylococcus aureus (MRSA), Staphylococcus epidermidis, Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli, Candida auris, Candida albicans, and Candida tropicalis. The antibiofilm efficacy was tested using the Crystal violet assay. Results: UV-Vis spectroscopy confirmed AgNP formation with a characteristic absorption peak at 412 nm. FTIR analysis identified the presence of hydroxyl, nitrile, and alkyne functional groups, which are involved in nanoparticle reduction and stabilization. TEM and SEM revealed predominantly spherical AgNPs with sizes ranging from 17 to 72 nm, while EDX confirmed silver as the major elemental component. DLS analysis showed a Z-average particle size of 113.9 \u00b1 67.75 nm and a zeta potential of -24.2 mV. The synthesized AgNPs exhibited concentration-dependent antimicrobial activity, producing inhibition zones of 10-20 mm at 240 \u00b5g/mL. MIC values ranged from 6.25 to 25 \u00b5g/mL, whereas MBC and MFC values ranged from 6.25 to 50 \u00b5g/mL and 25 to 100 \u00b5g/mL, respectively. Moreover, bacterial growth kinetics analysis demonstrated a concentration-dependent inhibition of growth by AgNPs at MIC and sub-MIC concentrations. Additionally, AgNPs demonstrated significant antibiofilm activity against P. aeruginosa and S. epidermidis.Conclusions: Overall, B. subtilis CG1-mediated AgNPs exhibited promising physicochemical properties and antimicrobial and antibiofilm activities, suggesting their potential as alternatives for combating resistant and biofilm-associated infections.\n\nID: 42515081\nTitle: Phosphoproteomics of WHO-Priority Fungal Pathogens: Conserved Signaling Architecture, Pathogen-Specific Outputs, and Therapeutic Vulnerabilities.\nAbstract: Protein phosphorylation is a central post-translational modification. In pathogenic fungi, it dynamically governs morphogenesis, stress adaptation, and antifungal drug resistance. Using high-resolution mass spectrometry-based phosphoproteomics, researchers have systematically mapped phosphorylation dynamics in WHO-priority pathogens-Candida albicans, Aspergillus fumigatus, Cryptococcus neoformans, and the multidrug-resistant Candidozyma auris (formerly Candida auris). These studies reveal that thousands of phosphorylation events are coordinately reprogrammed in response to antifungal drug exposure, host-derived oxidative stress, and temperature shifts. Integration of available datasets suggests a \"conserved-core/divergent-output\" organization. Shared kinase hubs like cAMP-PKA, HOG-MAPK and calcineurin are broadly conserved across species. Downstream substrate networks, however, have diverged, producing distinct virulence outputs in each pathogen. Notably, C. auris remains completely uncharacterized at the phosphoproteomic level. This review provides a comprehensive synthesis of the phosphoproteomic landscape across these pathogens, and discusses how phosphoproteomic data are guiding the rational prioritization of kinases and phosphatases as next-generation antifungal drug targets-with direct implications for clinical surveillance and public health.\n\nID: 42513906\nTitle: Comparative Analysis of Virulence Traits and Fluconazole-Response Mechanisms in Clinical Isolates of Candidozyma auris.\nAbstract: Candidozyma auris (formerly known as Candida auris) has emerged as a formidable clinical fungal pathogen as a result of its multidrug resistance and persistent colonization capabilities. In this study, three clinical C. auris strains (namely C. auris strain 01, C. auris strain 03, and C. auris strain 13) with distinct origins were characterized to investigate their phenotypic variations and mechanisms of azole resistance. Comprehensive profiling revealed significant inter-strain differences in biofilm formation, cell surface hydrophobicity, adhesion capacity, and phospholipase activity. Testing for antifungal susceptibility showed that the three clinical strains exhibited different minimum inhibitory concentrations for multiple azoles (fluconazole, voriconazole, and itraconazole) and echinocandins (anidulafungin and micafungin). Sequencing identified Y132F mutations in the ERG11 gene of the three clinical strains. Mechanistic investigations demonstrated that fluconazole exposure significantly upregulated the expression of efflux pump genes (CDR1 and CDR2) and the genes encoding their transcriptional regulators (MDR1 and TAC1b). In a murine skin colonization model, comparing data from the standard strain C. auris strain CBS12766 and clinical strains of C. auris strain 03 and C. auris strain 13 exhibited a significantly higher fungal burden of tissue, whereas strain C. auris strain 01 showed an intermediate level. Host immunity response analysis revealed that expression of the IL-1\u03b2 gene was significantly elevated in C. auris strain CBS12766-infected mice, while expression of IL-6 and CXCL-1 genes was predominantly increased in the C. auris strain 01, with TNF-\u03b1 gene expression levels being comparable across all strains. Histopathological examination confirmed local infiltration of inflammatory cells and mild epidermal edema, indicating active host immune engagement. Overall, our findings highlighted substantial phenotypic heterogeneity, different colonization capacities, and differences in expression of inflammatory cytokines among the C. auris strains. Further investigations into fluconazole-response mechanisms identified enhanced efflux pump activity, along with ERG11 gene Y132F mutations and transcription factor modulation among these clinical strains.\n\nID: 42506298\nTitle: Clinical Outcomes of Micafungin and Anidulafungin in Candidozyma auris (Formerly Candida auris) Candidemia: A Propensity Score-Matched Retrospective Cohort Study.\nAbstract: Candidozyma auris (formerly Candida auris) is a critical-priority multidrug-resistant pathogen. Comparative clinical data on first-line echinocandins-micafungin and anidulafungin-in C. auris candidemia remain limited. This retrospective cohort study compared clinical outcomes of micafungin and anidulafungin in adult patients with C. auris candidemia treated between January 2024 and December 2025 at three affiliated hospital campuses in Istanbul, T\u00fcrkiye. Propensity score matching (PSM) using a 1:1 nearest-neighbor algorithm was performed to balance baseline characteristics. Outcomes included 30-day (primary) and 14-day all-cause mortality, microbiological response, end-of-therapy (EOT) response, relapse, and drug-induced liver injury assessed by the Roussel Uclaf Causality Assessment Method (RUCAM). Among 154 included patients (micafungin, n = 94; anidulafungin, n = 60), no echinocandin resistance was detected. After PSM (55 matched pairs), 30-day all-cause mortality was identical between groups (41.8% vs. 41.8%; mOR 1.00, 95% CI 0.43-2.31; p = 1.000). Fourteen-day all-cause mortality (16.4% vs. 18.2%; p = 0.763), microbiological response (94.5% vs. 90.9%; p = 0.480), EOT response (74.5% vs. 67.3%; p = 0.346), and relapse (12.7% vs. 10.9%; p = 0.763) did not differ significantly between groups. RUCAM-based hepatic safety profiles were descriptively comparable. Micafungin and anidulafungin showed comparable observed outcomes in C. auris candidemia in this cohort.\n\nID: 42506280\nTitle: Risk Factors for Mortality in Candida auris Bloodstream Infection: A Multicenter Study in South Korea, 2018-2025.\nAbstract: Candida auris (C. auris) is a multidrug-resistant pathogen that spreads clonally in healthcare settings and was designated an urgent threat by the Centers for Disease Control and Prevention in 2019. We conducted a multicenter study to identify mortality risk factors in C. auris bloodstream infection (BSI) in South Korea. In this retrospective cohort study across three tertiary centers, 50 adults with first-episode C. auris BSI were analyzed. Primary and secondary outcomes were 30- and 90-day mortality. 30-day mortality was 24%, and 90-day mortality was 46%. Older age and higher Sequential Organ Failure Assessment score were independently associated with 30-day mortality. Microbiologic clearance within 30 days was protective. For 90-day mortality, older age was the only independent risk factor, and microbiologic clearance within 90 days was also protective. In conclusion, C. auris BSI causes substantial 30-day mortality, underscoring the need for risk-stratified, clearance-focused management.\n\nID: 42506257\nTitle: Clinical Outcomes of Candida auris Versus Other Candida Species Bloodstream Infections: An IPTW-Adjusted Cohort Study in South Korea.\nAbstract: Candida auris has emerged as a multidrug-resistant, healthcare-associated pathogen worldwide; however, outcome data on C. auris candidaemia in East Asia remain limited. We conducted a retrospective cohort study of adult patients with candidaemia who received antifungal therapy at a tertiary hospital in Seoul, Republic of Korea, from January 2023 to December 2024, comparing C. auris with other Candida species. Confounding was addressed by inverse probability of treatment weighting (IPTW) using a five-covariate propensity score (age, Charlson Comorbidity Index, septic shock, ICU admission at antifungal initiation, and concomitant Gram-negative infection). Among 423 patients, C. auris accounted for 6.9% of cases and was uniformly fluconazole non-susceptible, with frequent high-level caspofungin resistance but preserved micafungin and anidulafungin susceptibility. Patients with C. auris were older, with greater comorbidity and more frequent ICU admission at antifungal initiation. After IPTW adjustment, C. auris was not associated with higher 30-day mortality, the primary outcome (adjusted hazard ratio 0.59, 95% CI 0.26-1.32); the wide confidence interval indicates limited precision rather than equivalence, and results were directionally consistent for 90-day and in-hospital mortality and across sensitivity analyses that varied both the comparison cohort and the analytic method. Residual confounding by unmeasured illness severity and limited precision preclude concluding equivalence. Continued surveillance, molecular characterisation, and infection control remain essential.\n\nID: 42505655\nTitle: Field Evaluation of the ClaID PCR System Reveals Predominance of Clade I-Associated Molecular Profiles Among Clinical Candida auris Isolates Recovered in \u0130stanbul, T\u00fcrkiye.\nAbstract: Background:Candida auris has emerged globally as a multidrug-resistant fungal pathogen responsible for healthcare-associated outbreaks and invasive infections. Whole-genome sequencing studies have demonstrated the existence of genetically distinct clades that differ in geographical distribution, antifungal resistance patterns, virulence traits, and outbreak potential. Objectives: This study aimed to evaluate the performance of the ClaID clade identification PCR system among clinical Candida auris isolates collected in \u0130stanbul, T\u00fcrkiye, and to investigate the clade-associated molecular profiles of circulating isolates. Methods: Forty-four clinical C. auris isolates were analysed using the auris universal sequence (AUS) assay and clade-specific sequence assays (CSS1-CSS5). PCR amplification results were interpreted according to the ClaID framework. Results: AUS amplification was detected in 41/44 isolates (93.2%). CSS1 amplification was observed in 39/44 isolates (88.6%), indicating a predominance of Clade I-associated molecular profiles within this regional \u0130stanbul isolate collection. No amplification was detected using CSS2, CSS3, CSS4, or CSS5 assays. Three isolates were AUS-negative and five isolates did not yield CSS1 amplification despite repeated testing. Conclusions: The findings suggest that the majority of analyzed clinical isolates from \u0130stanbul exhibited Clade I-associated molecular profiles rather than definitive WGS-confirmed clade assignments. This study provides one of the first field evaluations of the ClaID system in a Turkish clinical isolate collection and contributes regional molecular epidemiological data regarding PCR-based clade-associated profiles of C. auris in T\u00fcrkiye.\n\nID: 42505599\nTitle: Changes in Antimicrobial Resistance Patterns in Intensive Care Units Following the COVID-19 Pandemic: A 10-Year Retrospective Study from T\u00fcrkiye.\nAbstract: The coronavirus disease 2019 (COVID-19) pandemic coincided with substantial changes in healthcare delivery and antimicrobial resistance (AMR) patterns worldwide, particularly in intensive care units (ICUs), where invasive procedures and broad-spectrum antibiotics are commonly used. Data from T\u00fcrkiye remains limited. This retrospective observational study evaluated bacterial and fungal isolates from adult ICU patients at a tertiary hospital from 2016 to 2025. Microorganisms were identified, and antimicrobial susceptibility testing was performed using standardized methods. Resistance patterns were compared between the pre-pandemic (January 2016-February 2020) and post-pandemic (March 2020-May 2025) periods. A total of 2666 patients and 5433 isolates were analyzed. Gram-negative pathogens showed marked increases in resistance: carbapenem and colistin resistance in Klebsiella pneumoniae were significantly higher in the post-pandemic period (69.6% vs. 44.4% and 60.5% vs. 22.5%, respectively; p < 0.001). Resistance rates to multiple antimicrobial agents also increased in Acinetobacter baumannii and Pseudomonas aeruginosa (p < 0.05). Among Gram-positive bacteria, vancomycin-resistant Enterococcus faecium increased from 10% to 47.1%. Candida auris emerged only in the post-pandemic period, showing high resistance to fluconazole (75%) and amphotericin B (36.7%). Significant differences in AMR patterns were observed between the pre- and post-pandemic periods in this ICU population. Higher resistance rates were observed among several clinically important bacterial pathogens, and Candida auris emerged exclusively during the post-pandemic period. Given the study's observational design, these findings should be interpreted as temporal associations rather than evidence of a causal effect of the COVID-19 pandemic. Continued antimicrobial stewardship and infection-control measures remain essential to address the growing burden of AMR.\n\nID: 42499548\nTitle: Candida auris: a review of global epidemiology, multidrug resistance, and infection control in healthcare-associated outbreaks.\nAbstract: Candida auris, designated a critical-priority fungal pathogen by the World Health Organization, poses a growing threat to healthcare systems worldwide. Analysis of 80 peer-reviewed studies reveals five principal findings: (1) C. auris exhibits clade-dependent geographic distribution and resistance profiles-Clade I (South Asia) and Clade III show fluconazole resistance exceeding 90%, whereas Clade IV exhibits 44% resistance; echinocandin resistance varies significantly by clade and no resistance was detected in certain clades; amphotericin B resistance varies from no detected resistance to 46% depending on clade; and pan-resistant strains have emerged; (2) biofilm-associated C. auris cells (sessile cells) exhibit MBECs 2- to 4,119-fold higher than planktonic MICs, representing a major driver of persistent colonization; (3) novel antifungal agents, including ibrexafungerp, manogepix (the active moiety of fosmanogepix), and rezafungin, demonstrate promising in vitro activity against C. auris, with manogepix showing the highest overall antibiofilm activity (geometric mean MBEC of 5.9 \u03bcg/mL) and ibrexafungerp demonstrating superior activity against Clade IV biofilms; (4) a tiered infection prevention and control (IPC) framework-integrating universal screening, contact precautions, and environmental decontamination-has been associated with reduced transmission rates in outbreak settings; and (5) climate change and global warming may have contributed to the emergence of C. auris through thermal adaptation of environmental fungal species. These findings indicate that effective mitigation of the C. auris threat requires integrated surveillance, susceptibility-guided therapy accounting for both planktonic and biofilm activity, and resilient healthcare systems adapted to the clade-specific epidemiology of this pathogen.\n\nID: 42497227\nTitle: Clinical and microbiological epidemiology of Candida infections in a high-complexity hospital in Tolima, Colombia (2014-2024).\nAbstract: Candida spp. infections are an increasing challenge in high-complexity hospitals, yet epidemiological data remain scarce in underrepresented in Colombian regions such as Tolima. We conducted a retrospective observational study in a high-complexity hospital in Ibagu\u00e9 (Tolima, Colombia) from 2014 to 2024, integrating two institutional data sources: administrative/clinical records and the microbiology laboratory database (WHONET). Species identification relied on culture and VITEK, and antifungal susceptibility was interpreted using criteria from the Clinical and Laboratory Standards Institute (CLSI) and the European Committee on Antimicrobial Susceptibility Testing (EUCAST). We summarized data using frequencies/proportions and medians (IQR), explored patterns with multiple correspondence analysis (MCA), and estimated associations with candidemia using penalized multivariable logistic regression due to low event frequency. We identified 987 candidiasis episodes and 776 fungal isolates, of which 314 were Candida (40.46%). Mucocutaneous disease predominated (vulvovaginal 50.7%; oropharyngeal 24.3%), while candidemia represented 2.0% of episodes. Among isolates, Candida albicans was most frequent (58.9%), followed by C. parapsilosis (16.6%), C. tropicalis (12.1%), and Nakaseomyces glabratus (6.4%); Candida auris was detected once. In exploratory clinical/administrative models, clinically recorded candidemia showed associations with invasive devices (OR 5.54, 95% CI 2.01-15.64), recent surgery (OR 7.11, 95% CI 1.20-30.88) and tumor (OR 19.88, 95% CI 3.14-97.51). Susceptibility data were available for 196/314 isolates (62.4%); echinocandin activity was high, whereas azole susceptibility was more variable. Candidiasis showed a sustained recorded burden and substantial non-albicans diversity, supporting local surveillance, species-level identification, and isolate-level susceptibility testing.\n\nID: 42487702\nTitle: Differentiation of Candida auris from other pathogenic yeasts using near-infrared spectroscopy and multivariate analysis: a proof-of-concept study.\nAbstract: Candida (Candidozyma) auris has emerged as a major public health concern due to its multidrug resistance, high mortality rates, and outbreak potential. These challenges are intensified by the difficulty of accurately identifying this species, particularly in settings with limited laboratory resources. This difficulty arises because C. auris is closely related to other yeast species, such as those within the Candida haemulonii complex. Although we previously demonstrated that near-infrared spectroscopy (NIRS) combined with multivariate analysis can discriminate C. auris from C. haemulonii stricto sensu, its performance against other clinically important yeasts had not been evaluated. In this study, we assessed NIRS coupled with different multivariate analytical techniques as a tool for distinguishing C. auris from C. haemulonii, C. albicans, C. tropicalis, C. parapsilosis, Nakaseomyces glabrata (formerly C. glabrata), and Pichia kudriavzevii (formerly C. krusei). Each of the seven species was cultured on fifteen Sabouraud Dextrose agar plates at 37 \u00b0C. After 72 h, three isolated colonies per plate (45 colonies per species) were subjected to Fourier-transform NIR analysis, resulting in a total of 315 spectra. The spectra were preprocessed and analyzed using principal component analysis (PCA), successive projections algorithm (SPA), genetic algorithm (GA), and linear discriminant analysis (LDA) to construct classification models. The combination of PCA, SPA, and GA with LDA achieved 100% sensitivity, specificity, and accuracy. These findings demonstrate that NIRS coupled with multivariate analysis can reliably differentiate C. auris from other medically important yeasts. The models also showed strong discriminatory capacity among the most prevalent pathogenic yeast species, reinforcing the promise of this approach as a rapid diagnostic tool for overcoming current identification challenges.\n\nID: 42483585\nTitle: Wastewater-Based Epidemiology for Infectious Diseases: A New Trick for an Old Threat.\nAbstract: Wastewater-based epidemiology (WBE) is an innovative approach to epidemiology that offers unique opportunities for public health surveillance. Its potential had been recognized in various applications over the years, but it was the global scale of the response to the SARS-CoV-2 pandemic that truly brought WBE to the fore. In this perspective paper we explore the untapped potential of WBE as a catalyst for infectious disease surveillance and as a One Health epidemiological tool, and the future horizons and innovative applications of WBE. It is clear that WBE will address a growing number of pathogens of concern to human health, such as avian influenza viruses, mpox, enterovirus D68, Candida auris, and antimicrobial resistance. In addition, it will contribute to epidemic intelligence by monitoring mass gathering events, and by predictive modeling and forecasting in combination with artificial intelligence to mitigate and prevent infectious diseases from reaching the highest level of clinical complexity. We believe that the maximum performance and complete institutional integration into public health of WBE is yet to be realized on a global scale.\n\nID: 42474134\nTitle: Pharmacological advances in Candida auris: emerging antifungal mechanisms and next-generation therapeutic strategies.\nAbstract: Candida auris is a major public health concern worldwide due to its efficient transmission, environmental persistence, and broad resistance to approved antifungal classes. This review consolidates recent pharmacological developments in this regard, focusing on mechanistic insights and late-stage therapeutics. Novel agents demonstrate activity against multidrug- and pan-resistant isolates via distinct mechanisms of action and enhanced specific binding to CYP51. Repositioned drugs, host-defense peptides, and quorum-sensing modulators also expand the treatable spectrum, particularly for biofilm-associated and device-related infections. Concurrently, artificial intelligence (AI)-guided discovery, nanocarrier-enabled delivery, and multi-omics profiling are greatly accelerating target identification and enhancing the drug metabolism of small-molecule fragments. The emerging combined approaches mark a transition towards mechanism-based antifungal development to combat the increasing clinical burden posed by C. auris. Ongoing integration of precision diagnostics, pharmacodynamic optimization, and novel discovery platforms will be key to translating these advances into durable, real-world therapeutic solutions.\n\nID: 42470541\nTitle: Environmental Detection of Candidozyma (Candida) auris in Surface Waters of the Gediz Delta, a Critical Coastal Wetland in T\u00fcrkiye: Expanding One Health Surveillance Perspective.\nAbstract: Candidozyma auris (syn. Candida auris) is an emerging multidrug-resistant yeast of growing clinical and environmental concern. Despite its increasing detection in healthcare settings worldwide, environmental evidence remains scarce. This study presents the first molecular detection of C. auris DNA in surface waters of T\u00fcrkiye, within the Ramsar-protected Gediz Delta, as part of the national One Health Surveillance Framework. A total of 80 surface-water samples were collected from five wetland ecosystems Tuz Lake, Kulu Lake, G\u00f6ksu Delta (Akg\u00f6l and Paradeniz Lagoons), K\u0131z\u0131l\u0131rmak Delta, and Gediz Delta. Physicochemical parameters; temperature, pH, and salinity were recorded in situ using a multi parameter sensor. Environmental DNA was extracted from 2\u00a0L of 0.22\u00a0\u00b5m Sterivex-filtered water and analyzed via qPCR using C. auris-specific (CauF/CauR) and Candida-genus (CauRelF/CauRelR) primer sets. Yeast isolation was performed on CHROMagar\u2122 Candida Plus, and identification was achieved by MALDI-TOF MS. C. auris DNA was detected in one sample (1.25%), specifically from the Gediz Delta (Sample No. 5651, 38.523\u00b0\u00a0N, 26.892\u00b0\u00a0E), with Ct values 33.8-37.2 confirmed by sequencing. Broader Candida genus signals were observed in 24% of samples. Culture-based analyses yielded no viable C. auris, but 15 yeast isolates were identified, mainly Pichia kudriavzevii (Candida krusei), C. albicans, and Nakaseomyces glabratus (Candida glabrata). The culture-negative yet qPCR-positive finding indicates that C. auris DNA likely persists in aquatic environments as non-viable or residual material. This finding provides early molecular evidence of environmental dissemination and underscores the need for viability assays, culture-based isolation, and metagenomic monitoring integrated within One Health surveillance programmes.\n\nID: 42466666\nTitle: Candida auris in Europe: Epidemiology and antifungal resistance. A systematic review.\nAbstract: Candida auris is a widely distributed yeast that is considered a dangerous pathogen, with reported mortality rates ranging from 30% to 60%. This yeast shows a high level of resistance to several antifungal agents commonly used to treat systemic infections. The pathogen persists on contaminated surfaces, tolerates hospital-grade disinfectants, survives desiccation and spreads easily through direct or indirect contact. It has been reported on all five continents and is increasingly prevalent in Europe. To determine the distribution and antifungal susceptibility/resistance of Candida auris isolates identified in Europe until January 2025. This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Searches were conducted in EBSCOhost, MEDLINE/PubMed, Scopus and SciELO databases using the terms 'Candida auris' and 'Candidozyma auris', combined with the name of each European country. It was limited to English or Spanish articles published until 31 January 2025, excluding reviews, meta-analyses and book chapters. Ninety-one articles reporting antifungal susceptibility were retrieved, covering 2191 clinical isolates of C.\u2009auris from 16 countries. Most isolates were from Spain (n\u2009=\u2009886, 40.44%), Italy (n\u2009=\u2009553, 25.24%), Greece (n\u2009=\u2009214, 9.77%), the United Kingdom (n\u2009=\u2009182, 8.31%) and Russia (n\u2009=\u2009108, 4.93%), accounting for 88.68% of cases. The remaining 248 isolates (11.32%) were reported across 11 other countries. Fluconazole resistance was found in 90.51% (1555/1718), while resistance to amphotericin B and echinocandins was 13.17% (223/1693) and 4.57% (76/1693), respectively. Candida auris has been predominantly detected in Southern Europe, where the majority of clinical isolates exhibit resistance to fluconazole. Consensus is essential for timely diagnosis, targeted treatment and infection control to prevent its spread. New therapeutic options must be explored to manage Candida auris.\n\nID: 42460008\nTitle: In vitro and in vivo antifungal effects of fluconazole in combination with Cinnamomum verum essential oil against Candida spp.\nAbstract: Antifungal resistance in Candida species is a growing clinical problem globally, especially in immunocompromised patients. One of the alternative approaches to conventional therapies are currently based on essential oils (EOs) alone or in combination with antifungals. We aimed to evaluate the antifungal activity of Cinnamomum verum EO, alone and in combination with fluconazole, against reference and multidrug-resistant (MDR) Candida strains by in vitro and in vivo assays. The chemical composition of the EO was analyzed by gas chromatography-mass spectrometry. Antifungal activity was assessed by broth microdilution (minimum inhibitory concentration determination), while anti-adherence effects were evaluated using the microtitration with crystal violet. The fractional inhibitory concentration index and response surface approach were used to study synergistic interactions. The in vivo efficacy was assessed by tracking virulence factors, fungal load, and larval survival in Galleria mellonella model. The most significant phenylpropanoid components of the EO were (E)-cinnamaldehyde and eugenol. It demonstrated high antifungal activity and significantly decreased adherence to the inert substratum. The tested EO exhibited pharmacological synergy in combination with fluconazole, especially against fluconazole-resistant Candida auris strains. The optimized fluconazole-EO combination decreased fungal virulence and load, as well as G. mellonella larval mortality. C. verum EO exhibits strong anti-virulence and antifungal effects and increases fluconazole activity, indicating its potential as an adjuvant treatment against resistant Candida infections.\n\nID: 42453987\nTitle: The anti-Candida haemulonii activity and bioactive metabolites of Streptomyces anandii NC-SA6.\nAbstract: The rapid advancement of multi-omics strategies has profoundly facilitated the in-depth exploration of microbial physiological characteristics, accelerated the discovery of novel bioactive secondary metabolites, and promoted the mechanistic elucidation of their biological functions. As a dominant genus within the phylum Actinomycetota, Streptomyces is widely recognized for its remarkable capacity to synthesize a diverse spectrum of clinically applicable antibiotics. Candida haemulonii, an emerging opportunistic fungal pathogen, has emerged as a typical multidrug-resistant species closely associated with outbreaks of nosocomial infections, posing a severe threat to clinical antifungal therapy. In this study, a novel strain designated as Streptomyces anandii NC-SA6 was isolated and systematically identified via gradient dilution method, multilocus sequence analysis (MLSA), coupled with comprehensive physiological and biochemical characterization assays. The optimal fermentation condition was optimized by controling a single variable method and measuring the diameter of the inhibition zone. The antimicrobial spectrum was tested against a panel of pathogenic strains, and the MIC value was measured by using broth microdilution. Finally, antifungal compounds were analyzed by combnining genome and metabolomic. We identified a strain with a spectrum antimicrobial activity against human pathogenic Candida species and Gram-positive bacteria. The optimal fermentation conditions are 4-day fermentation broth in No. 6 medium, and the MIC values of S. anandii NC-SA6 fermentation broth for Candida auris BJCA001 and Candida haemulonii 190070, the MIC50 values were 36.8 mg/ml and 18.4 mg/ml, respectively. Whole-genome sequencing analysis revealed the presence of 20 biosynthetic gene clusters (BGCs) responsible for secondary metabolite biosynthesis. Untargeted metabolomic analysis identified a total of 1703 metabolites. Functional annotation demonstrated that 43.5% of these metabolites were characterized bioactive compounds, including antimicrobial agents, antifungal agents, antitumor inhibitors, and other pharmaceutical molecules; the remaining 56.5% were uncharacterized metabolites, indicating the existence of potential secondary metabolites. Collectively, this integrated multi-omics study identified S. anandii NC-SA6 as a promising microbial resource for mining antifungal metabolites targeting multidrug-resistant C. haemulonii, highlighting its tremendous potential for the discovery and developmental research of novel antifungal agents.\n\nID: 42436212\nTitle: Designing a chimeric multi-epitope vaccine against Candida auris using reverse vaccinology approach targeting the agglutinin-like protein N-terminal domain.\nAbstract: Candida auris is an emerging multidrug resistant fungal pathogen associated with high mortality rates, rapid global dissemination and resistance to conventional antifungal therapies. It's remarkable ability to evade host immune responses and persist in health care setting demands the development of effective immunotherapeutic strategies. In this study, a reverse vaccinology and immunoinformatics based approach was employed to design a novel chimeric multi-epitope vaccine targeting surface expose N-terminal domain of the agglutinin like protein involved in host pathogen interactions. High affinity B-cell and T-cell (MHC class I and II) epitopes were identified and screened based on antigenicity, allergenicity, toxicity and population coverage. Selected epitopes were assembled using optimized linkers (EAAAK, AAY and GPGPG) along with an adjuvant to enhance immunogenicity and structural stability. Physicochemical characterization, structural validation, molecular docking with human Toll-like receptor 4 (TLR4), Normal Mode Analysis (NMA), immune simulation, codon optimization and in silico cloning into the pET28a+ vector were performed to evaluate the vaccine construct. The selected epitopes demonstrated a global population coverage of 97.31%. the final vaccine construct was predicted to highly antigenic, non-allergenic, structurally stable and soluble. Molecular docking analysis revealed strong and stable interactions between the vaccine construct and human TLR4, with a binding energy of - 906.1\u00a0kcal/mol. Normal Mode Analysis further supported the structural stability of the vaccine receptor complex. Immune simulations predicted robust primary and secondary responses characterized by elevated IgG and IgM antibodies along with a Th1-skewed cytokine profile dominated by IFN-\u03b3 and IL-2 expression. Codon optimization and in-silico cloning indicated favorable translational efficiency in the pET28a+ expression system. The designed chimeric multi epitope vaccine demonstrated promising immunogenic, structural and receptor binding properties against Candida auris. These findings suggest that the proposed vaccine construct may serve as a potential candidate for further experimental validation and future development of effective immunotherapeutic interventions against multidrug- resistant fungal infections.\n\nID: 42434388\nTitle: Candida auris Colonization in Hospitalized Patients at a Tertiary Care Center in Saudi Arabia: Clinical Characteristics, Predictors, and Outcomes.\nAbstract: Candida auris is an emerging fungal pathogen of global concern. Data on its epidemiology in the Middle East remain limited. We characterized the clinical profile, predictors, and outcomes of C. auris colonization among hospitalized patients in Saudi Arabia. A retrospective cohort study of 322 patients screened for C. auris between 2019 and 2025 at a tertiary care hospital in Riyadh. Patients were classified as C. auris positive (n = 107) or negative (n = 215). Baseline characteristics were compared using Mann-Whitney U and Fisher's exact tests. Logistic regression identified predictors of positivity. The C. auris positivity rate was 33.2%, declining from 58.1% in 2021 to 24.8% in 2024 as surveillance expanded. Positive patients were older (median 70 vs 59 years, P < .001) and had longer hospital stays (median 124 vs 21 days, P < .001). Cardiovascular, endocrine, renal, and hematological comorbidities were significantly more prevalent. Age (per 10 years: odds ratio [OR] 1.26, 95% confidence interval [CI] 1.12-1.42) and length of stay (per 30 days: OR 1.20, 95% CI 1.12-1.28) were the strongest continuous predictors. All-cause in-hospital mortality was higher in positive patients (51.4% vs 25.1%; OR 3.15, 95% CI 1.90-5.23, P < .001). Candida auris-positive patients exhibited advanced age, multimorbidity, prolonged hospitalization, and elevated all-cause mortality. These findings support targeted screening of high-risk populations in Gulf-region healthcare facilities.\n\nID: 42431934\nTitle: Segmental duplications and supernumerary chromosomes drive antifungal drug resistance in Candida auris.\nAbstract: Candida auris, a World Health Organisation-listed critical priority fungal pathogen, causes frequent multidrug-resistant outbreaks worldwide. While point mutations underlying antifungal resistance are well characterised, the contribution of structural genomic variation to antifungal responses remains poorly defined. Here, we integrate whole-genome sequencing, a genome-wide copy number variation (CNV) screen, electrophoretic karyotyping, and mutation-accumulation analyses to investigate the role of structural variation in antifungal susceptibility across a clinical cohort of C. auris isolates. We identify recurrent CNV hotspots, with segmental duplications representing a predominant mode of genome variation. Small duplications encompassing ERG11 arise at high frequency and frequently co-occur with drug resistance-associated ERG11 mutations, collectively enhancing azole resistance. In addition, large centromere-inclusive duplications of chromosome 1 generate supernumerary chromosomes, leading to paradoxical growth and reduced susceptibility to caspofungin, an echinocandin. At the population level, structural variants frequently arise in parallel to FKS1 mutations, suggesting multiple genetic mechanisms underlying reduced drug susceptibility. Together, our findings establish segmental duplication as a major, non-mutational driver of antifungal resistance, highlighting the need to consider structural genomic variation in both resistance surveillance and clinical susceptibility testing.\n\nID: 42424280\nTitle: Candida species identified by MAL-DI-TOF and antifungal susceptibility in hospitalized patients with COVID-19 in Peru.\nAbstract: To identify Candida species using MALDI-TOF and analyze their antifungal susceptibility from Candida genus isolates in hospitalized patients with COVID-19 between November 2020 and April 2022. An observational, descriptive, and cross-sectional study based on the se-condary analysis of microbiological and clinical-epidemiological data from 260 Candida isolates, primarily from urine, respiratory secretions, and blood cultures, referred to the National Reference Laboratory of Mycology of the National Institute of Health. Identification was performed using phenotypic techniques and MALDI-TOF, and antifungal susceptibility was evaluated using disk diffusion and broth microdilution according to Clinical and Laboratory Standards Institute (CLSI) criteria. Candida albicans was the most prevalent species (64.6%), followed by Candida tropicalis, Candida glabrata, Candida parapsilosis, and Candida auris. Most isolates showed susceptibility to voriconazole and caspofungin, while varying percentages of susceptibility to fluconazole were observed, especially in C. glabrata and C. auris. Minimum inhibitory concentration (MIC) values showed variability between species and antifungals. Non-albicans species represented a considerable proportion of the analyzed isolates. These findings descri-be the pattern of species and antifungal susceptibility in strains referred to the National Reference Labora-tory of Mycology of the National Institute of Health during the COVID-19 pandemic.

To evaluate in vitro synergistic antifungal activity of betulinic acid (BA) combined with four azoles (itraconazole [ITR], voriconazole [VOR], posaconazole [POS], fluconazole [FLC]) against Aspergillus spp., Candida spp., Exophiala dermatitidis, and Cryptococcus neoformans. Per CLSI M27-A3/M38-A2, broth microdilution checkerboard assay determined BA's minimum inhibitory concentration (MIC) and synergy with azoles (n\u202f=\u202f110); flow cytometry measured intracellular reactive oxygen species (ROS) in fungi co-cultured with BA. BA alone had no antifungal activity, but showed synergy with specific azoles: BA/POS had 82.7% (43/52) synergy against Aspergillus spp., 95.2% (20/21) against E. dermatitidis, and 70% (7/10) against Candida auris (of 28 Candida spp., 28.6% synergy). BA/FLC had 55.6% (5/9) synergy against C. neoformans. Among the 110 strains, the synergy rates of BA with POS, ITR and VOR were 66.4, 10.9 and 2.7%, respectively; the BA-FLC synergy rate was 18.5% in 27 strains. BA/POS co-culture increased fungal ROS. BA-POS reduces POS's MIC and exerts potent synergy against Aspergillus spp. and E. dermatitidis. BA has potential as an adjuvant for treating Aspergillus and E. dermatitidis infections.\n\nID: 42406015\nTitle: The Emerging Global Threat of Candida auris: A Call for Enhanced Public Health Policy and Regional Coordination.\nAbstract: Antimicrobial resistance represents a paramount challenge to global public health in the 21st century. The multidrug-resistant fungal pathogen Candida auris poses a critical and escalating threat to global public health. Characterized by rapid nosocomial transmission, persistent environmental contamination, and resistance to multiple antifungal classes, C. auris challenges healthcare systems worldwide. Its independent emergence across distinct geographic clades and exponential rise in cases, exacerbated by the COVID-19 pandemic, underscore the urgent need for robust, coordinated response. This review synthesizes the current knowledge on C. auris with a focus on its implications for public health policy, particularly in the European and Balkan healthcare settings, where surveillance gaps and cross-border transmission risks remain pronounced. We analyze the key drivers of spread, including diagnostic misidentification, extensive antifungal resistance, and lapses in infection control, and evaluate the strain on surveillance and hospital preparedness. Effective mitigation is fundamentally dependent on implementing comprehensive, multi-faceted infection prevention and control strategies, guided by antifungal stewardship and rapid diagnostics. We conclude that addressing the C. auris threat requires an urgent, coordinated international and regional response focused on strengthening surveillance networks, standardizing diagnostic and infection prevention and control protocols, and fostering data sharing across borders to contain this resilient pathogen.\n\nID: 42445483\nTitle: Integrative computational-experimental discovery and translation of antifungal peptides for multidrug-resistant fungi.\nAbstract: Multidrug-resistant fungal infections caused by Candida and Aspergillus species have become one of the major global health concerns, especially among immunocompromised individuals. The small number of antifungals available and the rapid emergence of resistance to azoles, echinocandins and polyenes underscore the urgent need to develop alternative therapeutic strategies with different mechanisms of action. Antifungal peptides (AFPs) have attracted increasing attention as promising candidates due to their broad-spectrum activity, multimodal mechanisms of action, and their low likelihood of resistance development. This review presents a thorough and holistic summary of the research on AFPs that target clinically significant drug-resistant fungi such as Candida auris, azole-resistant Candida albicans, and triazole-resistant Aspergillus fumigatus. We review the structural and physicochemical properties of AFPs and address their various antifungal mechanisms, which include membrane disruption, oxidative stress induction, and disruption of intracellular homeostasis, as well as biofilm inhibition. We further highlight an emerging computational-experimental pipeline to discover and optimize AFPs, combining sequence mining, machine learning-based screening, molecular docking, molecular dynamics simulations, and in vitro and in vivo validation. We also explore the major translational challenges, such as hemolytic toxicity, proteolytic instability, pharmacokinetic constraints, manufacturing complexity, regulatory concerns, and sustainable peptide manufacturing strategies, and discuss advanced delivery systems (e.g., liposomes, PLGA nanoparticles, chitosan-based systems, and hydrogels) to improve therapeutic efficacy and stability. In summary, this review proposes an integrated translational development framework that connects computational design, experimental validation, and delivery engineering, thereby positioning AFPs as a promising next-generation strategy in the fight against multidrug-resistant fungal infections.\n\nID: 42405804\nTitle: Morphotype-specific susceptibility to Neosartorya (Aspergillus) fischeri antifungal protein 2 is associated with an anabolic transcriptional signature in Candida.\nAbstract: The emergence of drug-resistant Candida species has created a demand for global antifungal strategies that extend beyond classical growth inhibition to target unknown vulnerabilities of fungal pathogens. In this study, we demonstrated that the Neosartorya (Aspergillus) fischeri antifungal protein NFAP2 selectively targets early morphogenetic states of Candida albicans and Candidozyma auris, revealing a transient window of susceptibility during filament and pseudohypha formation. Integrated transcriptomic and in vivo analyses indicate that these developmental states may represent context-dependent entry points for NFAP2 activity. In C. albicans, transcriptomic and network analyses indicate the presence of an anabolic, translation-associated gene expression signature, accompanied by suppression of stress-protective pathways, which is associated with increased susceptibility of emerging hyphae to NFAP2 but does not establish a direct causal mechanism. In C. auris, increased susceptibility of pseudohyphal cells occurred without overt transcriptional remodeling, consistent with the characteristically muted gene expression responses of this species, suggesting that NFAP2 sensitivity is governed primarily by biophysical and post-transcriptional mechanisms rather than transcriptional reprogramming. Importantly, morphotype-specific vulnerabilities observed in vitro were reflected in distinct in vivo outcomes in Galleria mellonella, as NFAP2 was well tolerated and provided a moderate, transient survival benefit in pseudohyphal C. auris infections, but not in filamentous C. albicans, where a worsened outcome was observed, consistent with species- and morphotype-dependent activity. Taken together, these results suggest that early morphogenetic states of Candida are stress-sensitive phenotypes associated with increased susceptibility to NFAP2. This work provides a proof-of-concept framework for future investigation of morphotype-associated antifungal vulnerability to peptide-based antifungal strategies.IMPORTANCEDrug-resistant Candida species represent an escalating global health threat; however, most antifungal strategies continue to target fungal growth rather than intrinsic biological vulnerabilities. In this study, we identified early morphogenetic transitions as a shared window of increased susceptibility in both Candida albicans and the highly drug-resistant pathogen Candidozyma (formerly Candida) auris. By integrating transcriptomic profiling with in vivo infection models, we found that NFAP2 exhibits antifungal activity that is influenced by these transient developmental states in a context-dependent manner while remaining well tolerated by the host. We further demonstrated that morphotype-specific stress responses are associated with the divergent sensitivities of C. albicans and C. auris to NFAP2. These results support the concept that fungal morphogenesis may represent a therapeutically actionable process and provide a framework for designing antifungal strategies that target developmental states rather than growth. This strategy may open new opportunities for improving protein- and peptide-based therapies, as well as combination therapies against difficult-to-treat fungal pathogens.\n\nID: 42390249\nTitle: Disinfectant tolerance of Candidozyma auris and Candida albicans biofilms evaluated using the bead assay for biofilms.\nAbstract: Candidozyma auris (formerly Candida auris) has emerged as a critical nosocomial pathogen, notable for its multidrug resistance and its capability to form biofilms that enable persistence on surfaces. Although effective disinfection strategies are urgently needed, current disinfectant efficacy standards in many regions, such as Europe, are primarily based on testing planktonic Candida albicans and do not adequately reflect the resilience of Candida biofilms, including those of C. albicans and C. auris. To address this gap, the Bead Assay for Biofilms, previously developed for bacterial biofilms, was adapted for the first time to eukaryotic cells. The goal was to cultivate C. auris and C. albicans biofilms and evaluate the efficacy of selected disinfectants across four active substance classes. Cell enumeration demonstrated highly reproducible biofilms, whose architecture was confirmed by scanning electron microscopy. Both an alcohol- and a QAC-based product did not achieve sufficient reduction of at least \u22654 log10 CFU/mL of biofilm-cells when applied under conditions recommended by the manufacturer (alcohol 1 min: C. auris 0.82, C. albicans 0.54; QAC 1%, 15 min: C. auris 1.94, C. albicans 0.68). This reduced efficacy is consistent with the known increased tolerance of microorganisms in biofilms. In contrast, peracetic acid and glutaraldehyde achieved sufficient reductions, albeit at relatively high concentrations (peracetic acid 0.1%: C. auris 4.75 and 0.05%: C. albicans 4.87; glutaraldehyde 0.5%: C. auris 5.32 and C. albicans 4.15). Our findings underscore the need to adapt disinfection protocols and testing models to consider biofilm formation of C. auris and C. albicans, and species-specific resilience.IMPORTANCEThis study highlights a critical gap in current disinfection efficacy testing standards; many of which rely on planktonic cell models and do not account for the resilience of biofilm-associated cells or emerging pathogens with unique resistance traits. Although species-specific regulatory guidance for C. auris exists in certain regions (e.g., in the USA), standardized disinfectant testing remains largely based on suspension assays (often using C. albicans) and does not routinely incorporate biofilm models. Using the Bead Assay for Biofilms, we demonstrate that several commonly used disinfectants may fail to inactivate biofilm-associated C. auris and C. albicans when applied as recommended. This suggests that reliance on planktonic testing may overestimate disinfectant efficacy against clinically relevant pathogenic yeast and highlights the need to expand current testing standards in order to include biofilm-associated pathogens to improve infection prevention strategies. Consequently, our research is of immediate relevance to regulatory bodies, infection control, and public health.\n\nID: 42370646\nTitle: HAC1 contributes to stress adaptation and virulence in the emerging fungal pathogen Candida auris.\nAbstract: Candida auris (Candidozyma auris) is an emerging multidrug-resistant fungal pathogen that poses a significant global health threat. However, the molecular mechanisms underlying its virulence remain incompletely understood. In this study, we performed in vivo transcriptome analysis using an immunosuppressed mouse gastrointestinal infection model to identify genes associated with host adaptation and virulence during infection. By comparing fungal transcriptomes obtained from colonization and dissemination sites with those from\u00a0in vitro cultures, we identified genes that were consistently upregulated during infection. Among these genes, the unfolded protein response regulator HAC1 was selected as a candidate virulence-associated gene for further analysis. Reverse transcription PCR and sequencing analyses revealed that\u00a0HAC1 mRNA in C. auris undergoes an unconventional splicing event of 287 bp that is enhanced under endoplasmic reticulum stress conditions. The excised region spans the annotated open reading frame boundary, suggesting that the translated region of\u00a0HAC1 may require re-evaluation. Notably, a proportion of HAC1 transcripts appeared to be spliced even under non-stress conditions, indicating a detectable basal level of the unfolded protein response. Differences in splicing dynamics were also observed among clade strains. Functional analyses demonstrated that deletion of\u00a0HAC1 increased sensitivity to endoplasmic reticulum stress. The HAC1 deletion mutant also exhibited reduced virulence in both Galleria mellonella and immunosuppressed mouse infection models, as evidenced by delayed host mortality and decreased fungal burdens, respectively. These findings indicate that HAC1 contributes to endoplasmic reticulum stress adaptation and survival in the host environment and identify\u00a0HAC1 as a virulence-associated gene in C. auris. Candida auris is an emerging multidrug-resistant fungal pathogen. Using in vivo transcriptome analysis, we identified HAC1 as a regulator of endoplasmic reticulum stress adaptation and virulence in infection models. This study provides new insight into stress-response pathways in C. auris virulence.\n\nID: 42369549\nTitle: A targeted drug-repurposing strategy identifies Tavaborole (Kerydin) as a potent fungistatic agent against Candida auris.\nAbstract: Candida auris is an emerging multidrug-resistant fungal pathogen posing a major global health threat. In this study, we employed a targeted drug-repurposing strategy to identify novel indications for existing FDA-approved compounds against C. auris, leading to the identification of Tavaborole as a potent fungistatic agent. Tavaborole displayed robust activity across all five tested clades of C. auris, as well as against Candida albicans and Candida glabrata. To investigate drug resistance mechanisms of C. auris, we applied quantitative proteomics analyses following exposure to Tavaborole and Amphotericin B (AmB), complemented by electron microscopy. Proteomic profiling revealed that C. auris mounts distinct but overlapping adaptive responses to antifungal stress, involving stress response pathways, metabolic reprogramming and amino acid biosynthesis. While Tavaborole primarily induced targeted stress adaptation, AmB triggered a broader, multi-pronged resistance response including oxidative stress mitigation, osmolyte production and metabolic remodeling. Shared alterations in glycogen metabolism and amino acid biosynthesis suggest conserved antifungal adaptation mechanisms. Altogether, this study highlights Tavaborole as a promising antifungal candidate against C. auris, sheds novel insights into drug resistance mechanisms employed by the pathogen and delivers a drug-repurposing procedure highly customizable to target other microorganisms.\n\nID: 42349555\nTitle: Disinfectant efficacy against Candida auris is driven by formulation and concentration rather than clade-specific resistance.\nAbstract: Candidozyma auris (formerly Candida auris) is a multi-drug-resistant pathogen of global concern due to environmental persistence, biofilm formation, and limited treatment options. Disinfectant efficacy is variable, particularly under high organic load, with reports of reduced susceptibility to Candida albicans. The aim of this study was to define the intrinsic chemical susceptibility of Candido auris clades I-IV and assess whether yeasticidal efficacy against Candida albicans predicts activity against Candido auris. Quantitative suspension tests (NEN-EN 13624:2022, dirty conditions) were used to evaluate six disinfectant chemistries: organic acid (lactic acid), halogen (chlorine), quaternary ammonium compounds, alcohol (ethanol), and oxidising agent (hydrogen peroxide). Testing was conducted in two independent laboratories using Candida albicans ATCC 10231 and Candido auris clades (I-IV). All chemistries achieved a \u22654 log10 reduction against Candida albicans and all Candido auris clades at validated conditions, with no consistent clade-dependent differences. Organic acid formulations showed comparable efficacy, highlighting a potential sustainable alternative. Candido auris shows susceptibility comparable with that of Candida albicans. Efficacy is driven by formulation, concentration, and contact time rather than clade variation, supporting formulation-based disinfection strategies for healthcare settings.\n\nID: 42348119\nTitle: Unraveling clade-specific differences in Candida auris: evolution, adaptation, and pathogenicity.\nAbstract: Since its 2009 emergence, Candida auris (now also known as Candidozyma auris) has evolved from a rare isolate into a global \"critical priority\" pathogen. This rapid expansion is defined by its unique population structure consisting of six distinct genomic clades with starkly different evolutionary trajectories, phenotypic traits, and clinical risks. We conducted a systematic synthesis of literature from PubMed, Scopus, and Google Scholar (2009-2026), focusing on comparative genomics, clade-specific virulence, and diagnostic accuracy. A total of 64 studies were analyzed to identify patterns in clade divergence and antifungal resistance. Our analysis reveals that C. auris is not a monolithic threat but a complex of diverse lineages with specialized adaptations. Clade I (South Asian) and Clade IV (South American) represent the highest clinical risk due to hyper-virulence and high rates of multi-drug resistant (MDR) strains. In contrast, Clade II (East Asian) was initially associated with localized ear infections; recent genomic data show an expanding pathogenic profile with emerging bloodstream infections. Our review also identifies Clade V (Iranian) as a genetically distinct group and highlights the recent identification of Clade VI (Indomalayan) as a distinct lineage, suggesting a long-standing environmental reservoir. Furthermore, we identify critical \"blind spots\" in automated diagnostic platforms (VITEK\u00ae 2, BD Phoenix) where phenotypic variations in Clades II and III lead to frequent misidentification as Candida haemulonii or Candida famata. This review proposes a \"clade-aware\" framework for public health. While frontline antifungal treatment remains standardized regardless of lineage, we argue that effective long-term management and outbreak containment require integrating genomic surveillance with clade-specific infection control. By identifying high-biofilm clades (Clade I) or hyper-virulent lineages (Clade IV), public health systems can implement more targeted containment strategies, moving toward a precision-based approach to managing this fungal pathogen.\n\nID: 42346566\nTitle: Recent Outbreaks, Resistance Trends, and Control Measures in Candida auris and Candida glabrata Infections.\nAbstract: The global rise in multidrug-resistant (MDR) fungal pathogens has positioned Candida auris and Candida glabrata as major threats to public health. In recent years, these pathogens have increasingly been reported beyond traditional hospital settings, including neonatal intensive care units, long-term care facilities, oncology wards, and post-pandemic critical care environments. International surveillance bodies, including the Centers for Disease Control and Prevention (CDC), European Centre for Disease Prevention and Control (ECDC), World Health Organization (WHO), and regional monitoring networks, have documented escalating antifungal resistance, complex outbreak dynamics, and persistent gaps in infection control implementation. C. auris has emerged as a major etiological agent of healthcare-associated outbreaks, particularly in intensive care and neonatal units. Surveillance data indicate that a high proportion of C. auris isolates exhibit resistance to azoles, often exceeding 80% in some regions, while echinocandin resistance remains variable. Resistance patterns have evolved from predominantly azole resistance to broader multidrug-resistant phenotypes, including treatment-emergent echinocandin resistance. Six genetically distinct clades (I-VI) have been identified, with Clades I, III, and IV associated with large-scale outbreaks, whereas available data suggests that Clades II, V, and VI are more geographically restricted, although evidence for the recently described clades remains limited. C. glabrata is increasingly recognized as a major cause of invasive candidiasis, with rising resistance reported across multiple regions. While reduced azole susceptibility was historically predominant, emerging evidence highlights rising dual azole-echinocandin resistance, adaptive microevolution during antifungal therapy, and biofilm-associated tolerance mechanisms. Despite these advances, significant gaps persist in global resistance surveillance and in the mechanistic understanding of virulence and antifungal adaptation. Current mitigation strategies include antifungal stewardship programs, expanded resistance testing, and strengthened surveillance systems. Advances in rapid diagnostic technologies such as matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry, polymerase chain reaction (PCR)-based assays, and genomic surveillance have improved pathogen identification and outbreak detection, although accessibility remains limited in resource-constrained settings. This review examines emerging epidemiological, genomic, and antifungal resistance trends in C. auris and C. glabrata and highlights key priorities for improving diagnosis, surveillance, stewardship, and management of multidrug-resistant Candida infections.\n\nID: 42298784\nTitle: Phenotypic switch Candidozyma auris (Candida auris) modulates biofilm formation and virulence genes SAP5 and ALS5 in mono- and co-culture environments with Staphylococcus aureus.\nAbstract: Candidozyma auris (formerly Candida auris) (C. auris), an emerging multidrug-resistant fungal pathogen, forms biofilms as a virulence factor. This study aimed to determine the effect of phenotypic switch on C. auris biofilm formation and virulence gene expression in mono- and co-culture with Staphylococcus aureus. Phenotypic switching was induced by prolonged incubation, and biofilms were developed in RPMI-1640, YEPD, SDB, and BHIYE. The biofilm biomass and total cell count were measured. SAP5 and ALS5 gene expression was quantified using qPCR. The 4th switched generation mono-culture biofilm in BHIYE produced the highest biomass (3.34\u2009\u00b1\u20090.08) and total cell count (5.66\u2009\u00b1\u20090.03 log10 cells mL-1). In addition, SAP5 and ALS5 expression peaked in the 2nd switched generation mono-culture by 10.43\u2009\u00b1\u20090.44-fold and 4.764\u2009\u00b1\u20090.01-fold, respectively. Co-culture biofilms exhibited significantly higher ALS5 expression in selected switched generations compared to unswitched C. auris (p\u2009<\u20090.05). In conclusion, phenotypic switching enhanced biofilm formation and modulated the expression of SAP5 and ALS5 in C. auris.\n\nID: 42283785\nTitle: Insights on molecular drivers of phenotypic plasticity in Candidozyma auris.\nAbstract: Candidozyma auris (or Candida auris) is the first fungal species declared as a global health threat by the U.S. Center for Disease Control and Prevention (CDC). Its high environmental persistence, immune evasion, phenotypic heterogeneity, and multidrug resistance are major contributors to its high mortality rate. Under diverse environmental conditions, C. auris exhibits marked phenotypic plasticity, switching from non-aggregative to aggregative form and, in some contexts, pseudohyphal-like morphotypes. However, the significance of this heterogeneity in pathogenesis and drug tolerance remains poorly understood. This review provides a comprehensive overview of how external cues influence C. auris morphotypes, with particular emphasis on aggregation. It further highlights the role of adhesion-associated genes (ALS4112 and SCF1) in mediating cell aggregation and examines their evolutionary trajectories across Candida species and among distinct C. auris clades. In addition, we discuss emerging molecular mechanisms that may underlie differential morphotypes and their links to virulence and antifungal tolerance. Evidence suggests that mannan-mediated masking of pathogen-associated molecular patterns (PAMPs) in the aggregative phenotype may contribute to persistence and reduced virulence in the host. Overall, C. auris can remodel its cell wall and elicit distinct host immune responses based on its form, opening avenues for novel therapeutic strategies which further require deeper experimental validation.\n\nID: 42280788\nTitle: Bioactive Potential of Post-Distillation Residue of Clinopodium albanicum (Griseb. ex K. Mal\u00fd) Melnikov: Phytochemical Profiling, Antioxidant and Antimicrobial Activities with Molecular Docking Insights.\nAbstract: The valorization of post-distillation by-products represents a key strategy within circular economy frameworks, particularly for medicinal and aromatic plants of the Lamiaceae family. This study investigates, for the first time, the chemical composition and biological potential of the liquid residue obtained after hydrodistillation of Clinopodium albanicum (Griseb. ex K.Mal\u00fd) Melnikov, an endemic Balkan species. Untargeted LC-HRMS/MS analysis revealed a complex metabolomic profile dominated by hydroxycinnamic acid derivatives, including caffeoylquinic acids, alongside a diverse flavonoid fraction comprising quercetin, kaempferol, apigenin, and acacetin derivatives. The presence of sugars and organic acids further indicated a broad metabolic composition. The evaporated liquid residual extract exhibited strong antioxidant activity (DPPH: 32.54, ABTS: 27.80, FRAP: 35.95 mmol GAE/100 mg). Pronounced antibacterial activity was observed against both Gram-positive and Gram-negative bacteria, including Staphylococcus aureus, MRSA, Listeria monocytogenes, Escherichia coli, and Pseudomonas aeruginosa (MICs 0.5-1 mg/mL). Additionally, the extract demonstrated antifungal activity against Candida auris and Candida parapsilosis, as well as strong antibiofilm effects against P. aeruginosa (up to 95.52% inhibition). Molecular docking supported these findings, revealing strong binding affinities of key phenolics toward the bacterial targets FabI and D-Ala-D-Ala ligase. Overall, the results highlight the potential of this by-product for nutraceutical and pharmaceutical applications.\n\nID: 42269829\nTitle: Clade-dependent antifungal resistance and susceptibility in Candidozyma auris: A global scoping review.\nAbstract: Candidozyma auris (formerly Candida auris) is an emerging multidrug-resistant fungal pathogen that has spread globally since its first identification in 2009 and is now classified as a critical-priority pathogen by the World Health Organization. Distinct genetic clades are associated with variations in geographic distribution, antifungal susceptibility, and resistance mechanisms; however, clade-specific evidence remains fragmented. To systematically map global evidence on clade diversity, antifungal susceptibility patterns, resistance mechanisms, and clinical implications of C. auris. A scoping review was conducted following PRISMA-ScR guidelines. Peer-reviewed primary studies published between 2009 and September 2025 were included if they reported clade attribution and antifungal susceptibility or resistance data. PubMed/MEDLINE, Scopus, and Web of Science were searched. Two reviewers independently screened studies and extracted data using a standardized form. Of 2050 records identified, 105 studies met inclusion criteria, representing 29 countries and diverse study designs. Whole-genome sequencing was the most common typing method. Antifungal susceptibility varied substantially across clades. High fluconazole resistance was consistently reported (MIC 4 to >256\u03bcg/mL). Echinocandins generally retained activity, although reduced susceptibility associated with FKS1 mutations was observed. Resistance mechanisms primarily involved mutations in ERG11, FKS1, and efflux-related genes. Studies also reported challenges in healthcare-associated transmission, environmental persistence, and diagnostic misidentification. C. auris exhibits marked clade-dependent variability in antifungal susceptibility and resistance mechanisms. These findings support the need for clade-informed interpretation of susceptibility data, standardized surveillance, improved diagnostics, and development of novel antifungal therapies.\n\nID: 42269828\nTitle: Liposomes loaded with Cymbopogon nardus L. Rendle essential oil: Characterization and potential in vitro and in vivo action against Candidozyma auris.\nAbstract: The rapid dissemination of Candidozyma auris (previously known as Candida auris) and its multidrug resistance profile poses a significant challenge in therapy once it contributes to a mortality of 30-60% of infected patients. This study aimed to evaluate the in vitro and in vivo antifungal activity of Cymbopogon nardus (L.) Rendle essential oil and citral oil, both free and incorporated into liposomes, against C. auris. The liposomes were composed of a lipid phase containing soy phosphatidylcholine, ergosterol, cholesterol and oleylamine, along with an aqueous phase consisting of PBS. The liposome was characterized by measuring the following features: hydrodynamic size, polydispersity index, zeta potential, transmission electron microscopy, infrared vibrational spectroscopy, thermogravimetry and differential scanning calorimetry, and transmission electron microscopy. The antifungal activity of the C. nardus essential oil, the citral oil and liposome-loaded compounds was determined by minimum inhibitory concentration (MIC), biofilm assay and by a Galleria mellonella infection model. G. mellonella was also used to assess acute in vivo toxicity. The liposomes exhibited sizes ranging from 218.8 to 261.7nm, polydispersity index <0.5, and a positive zeta potential. Furthermore, the liposomes showed good stability and a lipid layer in the outer region. Citral showed the best antifungal activity, with MIC 62.5\u03bcg/mL, being the compound selected for its incorporation into liposomes, which further improved its antifungal potential. Citral and citral-liposomes showed important metabolic inhibition in mature biofilms (20%). No acute toxicity was observed for either sample in G. mellonella, and citral-liposomes showed promising antifungal action in the G. mellonella infection model. Liposomes represent a promising strategy for the safe and effective delivery of citral to control C. auris infection.\n\nID: 42267094\nTitle: Prevalence, pattern of disease and antimicrobial susceptibility of Candidozyma auris in the greater Pretoria region from 2021 to 2024.\nAbstract: Candidozyma auris has emerged as a nosocomial pathogen in South Africa, characterised by multidrug resistance and environmental persistence. This study aimed to describe the prevalence, disease patterns, and antifungal susceptibility patterns of C. auris isolates recovered from public-sector healthcare facilities in the greater Pretoria region from 2021 to 2024. A retrospective laboratory-based surveillance study was conducted using data from the National Health Laboratory Service Tshwane Academic Division laboratory. Isolates were classified as invasive or non-invasive based on specimen source. Temporal trends in antifungal minimum inhibitory concentrations (MICs) were analysed using interval-censored regression. A total of 592 C. auris isolates were identified. Blood cultures were the most frequent specimen source overall, comprising 237 isolates (40.03%). Intravascular catheter tip isolates predominated in 2023 and 2024, with 48 and 72 isolates, respectively. The proportion of invasive isolates declined from 56.8% to 40.8% over the study period. Among tested isolates, fluconazole resistance exceeded 99%. Resistance to amphotericin B and echinocandins was uncommon, with eight total isolates identified. Decreasing MIC trends were observed for amphotericin B (\u03b2 = -0.059 per year; p = 0.012) and micafungin (\u03b2 = -0.081 per year; p = 0.026). Candidozyma auris remains established in the public-sector within the greater Pretoria region. There is a shift from invasive bloodstream infections towards non-invasive, device-associated isolates. Fluconazole resistance remained high while amphotericin B and echinocandins retained good in vitro activity. This study contributes to the knowledge of C. auris in the greater Pretoria region, providing insight into epidemiology and antifungal susceptibility.\n\nID: 42259815\nTitle: The Wor2 phenotypic switching regulator controls biofilm formation in Candida auris.\nAbstract: The emerging fungal pathogen Candida auris is a serious global public health threat due to its ability to persist in healthcare environments and on human skin. Here, we report a prevalent cluster of clinical C. auris strains with enhanced biofilm formation, a contributor to environmental and skin persistence. Genomic analyses show that the clinical isolates with enhanced biofilm formation ability carry a loss-of-function mutation in the WOR2 locus, which encodes a white-opaque switching regulator in Candida species. Analysis of 13,314 published genomes revealed that 3104 strains (23.3%) harbor nonsense or frameshift mutations in WOR2, indicating frequent clinical occurrence. Deletion of WOR2 in a clinical strain markedly increased biofilm formation, whereas reintroduction of an intact WOR2 significantly attenuated biofilm development. Further analyses show that Wor2 inactivation upregulates GFC1, ALS4, and multiple biofilm-associated genes. Together, these findings reveal a key regulatory mechanism underlying biofilm development, environmental persistence, and transmission of C. auris.\n\nID: 42229743\nTitle: Antifungal peptides for biofilm disruption: Mechanisms, design strategies, and translational outlook.\nAbstract: Invasive fungal infections in intensive care units are a serious concern, especially when they are associated with biofilm formation. These infections often lead to high mortality because biofilms make the fungi more resistant to antifungal drugs and harder for the immune system to clear. Pathogens such as Candida auris, Candida albicans, and Aspergillus fumigatus are particularly problematic, as they are known to develop multidrug resistance and cause persistent infections in critically ill patients. These biofilms often show a much higher tolerance to standard antifungal drugs and can escape the host body's immune defenses. This makes the infections they cause more persistent and very difficult to treat in clinical practice. Antifungal peptides (AFPs), whether derived from natural host-defense molecules or designed through rational engineering, are emerging as promising options for tackling fungal biofilms. They act through several mechanisms, such as disrupting the fungal cell membrane, blocking early adhesion and morphogenesis, and weakening the extracellular matrix. Importantly, they may also work in synergy with existing antifungal drugs, making treatment more effective. Recent progress in peptide engineering and delivery methods, such as nanocarriers and hydrogel-based systems has enhanced the stability, selectivity, and ability of peptides to target fungal biofilms in experimental models. At the same time, there are important challenges that remain, including their tendency to break down due to proteolytic enzymes, possible cytotoxic effects, difficulties in large scale manufacturing, and regulatory hurdles linked to peptide-based therapies. Overall, AFPs represent a promising and fast developing area of research, but their use in clinical practice is limited. More studies are needed to confirm their safety, effectiveness and practical feasibility for managing biofilm-associated fungal infections.\n\nID: 42211613\nTitle: Epidemiology, Distribution, Key Characteristics, and Challenges of Candidozyma auris (Formerly Candida auris): A Narrative Review With a Special Focus on T\u00fcrkiye.\nAbstract: This narrative review summarizes the epidemiology, microbiological and clinical features, antifungal resistance, transmission dynamics, and public health significance of Candidozyma auris globally and with a focus on T\u00fcrkiye. C. auris has emerged as an important fungal pathogen because of its capacity for healthcare-associated colonization, environmental persistence, biofilm formation, laboratory misidentification, and multidrug resistance. Available evidence suggests that its rapid global spread is related to environmental tolerance, skin colonization, interclade phenotypic differences, and antifungal resistance mechanisms. Reported cases from T\u00fcrkiye further support the need for strengthened infection control and surveillance systems. It represents a significant nosocomial fungal threat that necessitates the simultaneous implementation of clinical management and public health responses. In addition, it has been observed that the dominant clade in T\u00fcrkiye is Clade I, that early cases were misidentified due to laboratory method-related limitations, and that there are substantial variations in antifungal susceptibility even within the same case series.\n\nID: 42199049\nTitle: Mechanisms and species-specific patterns of ECM-mediated antifungal resistance in Candida biofilms: a systematic review and exploratory quantitative synthesis.\nAbstract: To synthesize mechanistic evidence on how extracellular matrix (ECM) components of Candida biofilms contribute to antifungal resistance across species and antifungal drug classes. We conducted a PRISMA-guided systematic review with exploratory random-effects quantitative synthesis of peer-reviewed experimental studies evaluating ECM composition, matrix-associated regulatory pathways and antifungal susceptibility in Candida biofilms. Qualitative synthesis mapped ECM components and pathways, while harmonizable semi-quantitative data were summarized as directional modeled estimates. Of 38 full-text records assessed, 33 primary studies were included in the qualitative synthesis and 25 contributed to the exploratory pooled analysis. Preservation or modulation of ECM-associated mechanisms showed a strong modeled directional association with reduced antifungal susceptibility (pooled modeled odds ratio: 4.28, 95% CI: 4.06-4.52). \u03b2-1,3-glucan was the most consistently supported sequestration scaffold, particularly for azoles and polyenes. Mannan-glucan complexes, matrix proteins, extracellular DNA and vesicle-associated lipids provided complementary structural and remodeling functions. Non-albicans Candida species, especially Candida glabrata and Candida auris, more often combined ECM protection with efflux-linked resistance. ECM-mediated resistance in Candida biofilms is multilayered, species-dependent and drug-class specific. These findings support species-aware interpretation of biofilm-associated antifungal resistance and further development of ECM-directed adjunctive strategies.\n\nID: 42184474\nTitle: Antifungal meroterpenoids from deep-sea-derived fungus Acremonium sclerotigenum.\nAbstract: Seven previously undescribed compounds, acrenoids A-G (1-7), along with two known compounds (8 and 9), were isolated from the culture of the deep-sea-derived fungus Acremonium sclerotigenum LW14. The structures of these compounds were characterized by a combination of spectroscopic studies, ECD calculations, and ECD experiments induced by Rh2(OCOCF3)4. Acrenoid A (1) features a distinctive 5/5/7 tricyclic ring framework. Moreover, all isolates were evaluated for their antifungal activities. Notably, compound 9 exhibited potent antifungal activity against drug-resistant Candida auris 12766, with a MIC of 4\u202f\u03bcg/mL. In addition, compound 9 exhibited low hemolytic toxicity. The antifungal mechanism of compound 9 involves cell membrane disruption and intracellular ROS accumulation. In addition to these effects, it also inhibited biofilm formation in C. auris 12766. These findings highlight compound 9 as a promising antifungal candidate for treating C. auris.\n\nID: 42119224\nTitle: Interplay between Candida auris and host immunity: Highlighting its unique strategies for resisting host immune responses.\nAbstract: Candida auris, an emerging \"super fungus,\" poses a global threat owing to multidrug resistance, rapid transmission, and high mortality. Distinct from other clinically prevalent fungal pathogens such as Candida species, C. auris employs unique defense mechanisms against the host immune system, including immune evasion and survival strategies. This review summarizes the distinct strategies used by C. auris to resist host immune responses. In particular, C. auris exhibits pronounced genomic and morphological plasticity, which facilitates rapid adaptation to host-derived stressors. Its modified cell wall, characterized by a thicker mannan layer, efficiently masks immunogenic \u03b2-glucan, thereby reducing immunogenicity. Furthermore, multicellular features, including robust biofilms and unique aggregative forms, enhance colonization, transmission, and stress resistance. C. auris also secretes diverse virulence factors and undergoes adaptive metabolic reprogramming under nutrient limitation, promoting more efficient immune evasion and survival within the host. Collectively, these flexible defensive strategies confer enhanced host immune resistance, contributing to its heightened pathogenicity. This review provides novel perspectives on future research directions and potential therapeutic strategies for managing C. auris infections.\n\nID: 42405803\nTitle: Candida spp. suppress neutrophil reactive nitrogen species to evade killing.\nAbstract: Candida albicans is a human commensal that can cause life-threatening invasive infection in immunocompromised individuals. Human immunity to C. albicans infection is thought to be largely dependent on neutrophil reactive oxygen and nitrogen species (ROS/RNS) generation by neutrophils. Despite this, our understanding of innate immune killing and escape by C. albicans is primarily studied in macrophages, and the precise mechanisms of evasion are unclear in neutrophils. Here, we sought to determine the importance of neutrophil reactive nitrogen species (RNS) production during C. albicans infection in vivo. Using a zebrafish model, we found that C. albicans rapidly downregulated neutrophil RNS below basal levels during the first day post-infection, a time at which neutrophil RNS is upregulated in bacterial infections as an important host-defense mechanism, indicating fungal evasion of host neutrophils. We confirmed the downregulation of RNS in human primary neutrophils and with clinical Candida isolates, including emerging human pathogens Candida auris and Candida glabrata. Inducible nitric oxide synthase (iNOS; Nos2 in zebrafish), the enzyme responsible for RNS production, competes with the arginase enzyme for a shared substrate, L-arginine. Using a zebrafish arginase2 transgenic line and a C. albicans car1\u0394 mutant, we showed that both host and fungal arginase contribute to the reduction in neutrophil RNS. Despite pathogen downregulation, upregulation of neutrophil RNS via hypoxia-inducible factor 1\u03b1 (Hif-1\u03b1) stabilization was sufficient to improve host survival following C. albicans infection. Inhibition of Nos2 blocked the host protective effect of Hif-1\u03b1 stabilization. Finally, restoration of neutrophil RNS via Hif-1\u03b1 stabilization was additive to clinically relevant antifungal treatment, increasing survival and clearance of C. albicans infections. Together, these data demonstrate that restoration of the neutrophil RNS response in C. albicans infection improves infection outcomes, highlighting the potential of targeting Hif-1\u03b1 and RNS in host-directed therapies against fungal infections.IMPORTANCECandida albicans is a fungus that normally lives harmlessly in the human body but can cause life-threatening infections in people with weakened immune systems. A key part of the body's defense against this fungus is neutrophils, immune cells that kill microbes using toxic molecules. However, how Candida avoids neutrophil defense is not well understood. Here, we used zebrafish and human immune cells to show that Candida suppresses an important neutrophil defense, reactive nitrogen species (RNS), during infection. Unlike bacteria, which trigger RNS, Candida reduces these protective molecules to below normal levels, helping its survival. This effect was also observed with other disease-causing Candida species. We went on to show that both the host and Candida contribute to this suppression. Importantly, boosting the neutrophil response improved survival and helped clear infection, especially when combined with standard antifungal drugs. These findings suggest new ways to support the immune system alongside existing treatments.\n\nID: 42385700\nTitle: Large-scale discovery platform enables identification of peptides targeting drug-resistant candidiasis.\nAbstract: Natural products have an unparalleled track record as sources of clinical drugs. Among them, nonribosomal peptides (NRPs) stand as one of the most therapeutically significant classes, encompassing numerous approved anti-infective and anticancer agents. Yet, discovering bioactive NRPs remains profoundly challenging due to their complex biosynthesis and chemical architecture. Here, we present NPDiscover, a pathogen-oriented, scalable bioinformatics platform that integrates genome mining, metabolomics, and machine learning to identify NRPs active against drug-resistant pathogens. Applying NPDiscover to Actinobacteria datasets, we discovered edaphochelin A, a previously unreported NRP that kills multi-drug-resistant Candida auris and Candida glabrata by disrupting respiratory chain proteins. Structural elucidation via nuclear magnetic resonance and mass spectrometry, alongside in vitro and in vivo validation, confirmed its efficacy, safety, and a mode of action distinct from existing antifungals-establishing edaphochelin A as a compelling drug candidate and NPDiscover as a powerful engine for scalable natural product discovery.\n\nID: 42270656\nTitle: Infection-induced glucose starvation triggers NINJ1-dependent macrophage lysis and Candida escape.\nAbstract: Pathogens compete for glucose with macrophages, which disrupts host glycolysis, modulates antimicrobial responses and causes macrophage death. We show that glucose starvation induced by major fungal pathogens Candida albicans and Candida auris causes macrophage lysis by activating NINJ1, the executioner of membrane rupture during cell death. In glucose-starved macrophages, NINJ1 ruptures membranes independently of known cell death programs. Consistently, NINJ1 is the dominant effector of fungal-induced macrophage damage amongst host cell death factors. Supplementation of the amino acid alanine rescues glucose-starved macrophages better than glucose, and it does so by inhibiting NINJ1 oligomerization. Moreover, C. albicans infection disrupts amino acid metabolism in mice and reduces serum alanine. Finally, NINJ1-mediated membrane rupture enables C. albicans egress from macrophages together with the toxin candidalysin. We establish the mechanism of glucose starvation-induced macrophage damage by NINJ1, and demonstrate the roles of NINJ1 and alanine in immune responses to Candida and fungal escape.\n\nID: 42035544\nTitle: Ethyl caffeate reprograms macrophage immunometabolism via the SIRT3-FOXO3A-AKT axis to enhance host defense against Candida auris.\nAbstract: Candida auris (C. auris) is an emerging multidrug-resistant fungal pathogen. Current antifungals are often insufficient, creating a need for host-directed strategies. Sirtuin 3 (SIRT3) is a mitochondrial deacetylase that regulates redox homeostasis, but its role in antifungal macrophage defense is not well defined. We examined how SIRT3 shapes macrophage responses to C. auris. We also evaluated ethyl caffeate (EC) as a host-directed modulator. We used murine macrophages with Sirt3 knockdown or overexpression. We quantified phagocytosis, intracellular fungal survival, mitochondrial ROS dynamics, and macrophage cell integrity using imaging, flow cytometry, CFU assays, and LDH release. We profiled infection-induced transcriptional programs by RNA-seq and performed pathway analyses. We tested EC both in vitro and in systemic infection models in Drosophila and mice. We assessed pathway markers by immunoblotting and immunofluorescence. We used the SIRT3 inhibitor 3-TYP to test inhibition sensitivity. SIRT3 deficiency impaired macrophage antifungal function and was accompanied by redox imbalance. mtROS regulation was disrupted in a biphasic pattern, with an early spike followed by late depletion. Transcriptomics linked SIRT3-dependent programs to FOXO and PI3K-AKT signaling. In macrophages, SIRT3 status tracked with FOXO3A acetylation and AKT phosphorylation. EC showed weak direct antifungal activity in vitro but improved outcomes in systemic infection models. EC treatment increased SIRT3 abundance and was associated with reduced FOXO3A acetylation and restrained infection-associated AKT activation. These functional and signaling effects were largely sensitive to SIRT3 inhibition by 3-TYP. This study connects SIRT3-dependent redox control to FOXO3A-AKT signaling during C. auris infection. It also supports EC as a host-directed candidate that improves antifungal defense in vivo while limiting inflammatory injury.\n\nID: 42009862\nTitle: Engineering Penicillium expansum antifungal proteins unveils new clues about their mode of action.\nAbstract: Fungal antifungal proteins (AFPs) are promising biofungicides. PeAfpA and PeAfpB from Penicillium expansum show different activity profiles and potency, with PeAfpA being more active. Based on the PeAfpB solved structure, we had previously designed PeAfpB-PeAfpA chimeras that showed different properties. From these, we engineer here two additional variants, chPeAFPV6 and chPeAFPV7, that revealed novel aspects of the AFP structure, antifungal determinants and mechanism. chPeAFPV6, with a single E11K mutation in the loop L1 that is part of the \u03b3-core motif, increased PeAfpB antifungal activity to that of PeAfpA against filamentous fungi but not yeasts, and promoted internalisation into Penicillium digitatum hyphae. However, changes in loop L3 of PeAfpB as in chPeAFPV7 abolished this increase, resulting in an inactive protein that still internalised. Overall, internalisation is neither sufficient nor essential for killing P. digitatum. Antifungal activity did not correlate with reactive oxygen species production, suggesting that oxidative burst is a fungal stress defence rather than a killing mechanism. Although cell permeabilisation was associated with antifungal activity, it does not seem to be a primary mode of action. Structural analysis showed interactions between the \u03b3-core motif and loop L3, and suggests the importance of the conformation of the E7 residue of PeAfpB. Additionally, PeAfpA was identified as a protein able to penetrate Candida auris by a cell wall-dependent mechanism, and kill yeast cells. This study highlights the potential of the PeAfpB scaffold for engineering new-to-nature AFPs and provides novel insights into their modes of action, paving the way for future applications. KEY POINTS: A single amino acid change in the \u03b3-core of PeAfpB enhances antifungal potency Loop L3 of PeAfpB may block activity through interaction with the \u03b3-core Antifungal activity does not correlate with ROS production.\n\nID: 42000719\nTitle: Wastewater intelligence predicts the emergence of clinically-relevant and drug-resistant Candidozyma auris at healthcare facilities.\nAbstract: The rapid evolution of antifungal resistance in Candidozyma auris (formerly Candida auris)\u00a0presents significant challenges for conventional public\u00a0health surveillance methods, particularly in detecting emergent and highly transmissible drug-resistant variants.\u00a0Here, using wastewater-based epidemiology tools initially developed during the COVID-19 pandemic, we implement a high-resolution, facility-level early warning system to monitor C. auris infections and resistance patterns. Our evaluation across Southern Nevada demonstrates that upstream sewage monitoring at healthcare facilities provides significant sensitivity (p\u2009<\u20090.001) compared to wastewater treatment plant sampling. By combining amplicon sequencing and MALDI-TOF mass spectrometry, we identify clinically-relevant, resistance-associated variants in wastewater samples, while whole-genome sequencing reveals >90% genomic concordance between 443 wastewater-derived genomes and 2945 clinical isolates. We also detect previously unreported subclades and resistance mutations, including FKS1 Phe635Leu and co-occurring ERG11/FKS1 variants in wastewater samples up to nearly five months before their appearance in clinical settings. Transcriptomic profiling of drug-resistant isolates under antifungal and stress conditions identifies previously uncharacterized adaptation mechanisms, including differential regulation of ribosomal assembly pathways and cell cycle checkpoints. These findings highlight how wastewater intelligence can enhance traditional public\u00a0health approaches for early detection and monitoring of C. auris outbreaks and antifungal resistance.\n\nID: 41922787\nTitle: Characterization and Antifungal Activity of Essential oil of Cymbopogon citratus: Special Emphasis on Preliminary Fungicidal Mechanisms against Candida auris and Cryptococcus neoformans.\nAbstract: In 2022, the World Health Organization published a list highlighting Candida auris and Cryptococcus neoformans as among the priority pathogens in need of new therapeutic alternatives. The essential oil of Cymbopogon citratus (EOCC) is used in folk medicine for its various properties, including antimicrobial activity. However, there are few reports of its activity against these yeasts and the possible action mechanism. EOCC was characterized by gas chromatography combined with mass spectrometry. Antifungal activity was determined by broth microdilution against C. parapsilosis ATCC 22,019, C. krusei ATCC 6258, C. auris 01256P, fluconazole-resistant C. albicans and C. neoformans strains. The possible mechanism of action of EOCC against C. auris and C. neoformans was investigated by flow cytometry and the alkaline comet assay. EOCC contained as major chemical compounds \u03b2-pinene (4.50%), neral (32.80%), geraniol (8.13%) and geranial (41.29%). EOCC had minimum inhibitory concentration (MIC50) of 32 to 256\u00a0\u00b5g/mL against Candida spp. and 32 to 128\u00a0\u00b5g/mL against C. neoformans. The antifungal effects of EOCC may be related to the high presence of neral and geranial detected in its phytochemical composition. The mechanism of action appeared to be related to mitochondrial dysfunction, an increase in reactive oxygen species and damage to fungal DNA, leading to apoptosis-like cell death.\n\nID: 41894321\nTitle: Host-Candida auris interactions in the skin.\nAbstract: Candida auris is an emerging, multidrug-resistant fungal pathogen that causes healthcare-associated outbreaks and life-threatening systemic infections. Unlike other Candida species, C. auris exhibits a distinct capacity for persistent skin colonization. In this review, we summarize our current understanding of clinical risk factors and host-microbe interactions that underlie C. auris skin colonization and infection. We discuss fungal determinants, including the unique mannan outer layer, fungal adhesins, the protein kinase Hog1, and other pathways in C. auris that govern adaptation in the skin. Furthermore, we highlight host immune mechanisms, including cytokine mediators (IL-1Ra, IL-17) and innate immune cells (neutrophils, macrophages, innate lymphocytes), that shape the outcome of C. auris skin colonization and infection. We also discuss how excessive IFN-\u03b3 responses drive epithelial pathology at the cutaneous barrier and enhance fungal persistence. Finally, we outline emerging research directions to understand host and microbe factors governing long-term colonization, with implications for developing novel therapeutic and vaccine strategies against this skin-tropic, multidrug-resistant fungal pathogen.\n\nID: 41893111\nTitle: Flavonoids as a Potential Antifungal Alternative Against Candida auris (Candidozyma auris) from Clades III and IV.\nAbstract: Candida auris is a critical emerging pathogen of high priority due to its ability to develop multidrug resistance to various antifungals. Given the increase in cases associated with C. auris, it is essential to evaluate new candidates with antifungal potential. In this context, flavonoids represent a promising source for the development of new therapeutic alternatives. In this study eleven flavonoids were evaluated for their antifungal activity against C. auris strains from clades III and IV. The flavonoids showed dose-dependent inhibition of C. auris growth. Toxicity tests were conducted using the in vivo Tenebrio molitor model. The flavonoids exhibited toxicity levels either comparable to or lower than reference antifungals. Also, the study examined the ability of the flavonoids to inhibit efflux pumps. Some of the flavonoids (quercetin, fisetin, hesperetin, luteolin and apigenin) reduced efflux pump activity, which is an important feature since these pumps actively expel antifungal drugs from the cell, reducing the drug's effectiveness. This suggests that the flavonoids might inhibit efflux pump activity, potentially enhancing the efficacy of antifungal treatments. The study supports the potential of flavonoids as new therapeutic agents for C. auris. Since they target efflux pumps, which are a significant mechanism of resistance in C. auris, flavonoids could be used either alone or in combination with existing antifungals to improve treatment outcomes.\n\nID: 41893106\nTitle: Genomic Analysis Reveals Diversified and Stress-Responsive Transport Repertoire in Candidozyma (Candida) auris.\nAbstract: Candidozyma (Candida) auris is a fungal pathogen associated with life-threatening invasive infections and high mortality rates. It is becoming a major global public health concern due to its ability to resist multiple antifungal drugs and spread in healthcare settings. Despite this, little is known about the mechanisms underlying drug resistance, fungal development, pathogenesis, and virulence. Among the factors contributing to these processes, transporters play a central role in fungal biology, regulating nutrient acquisition, metabolite exchange, ion homeostasis, and drug efflux. However, the composition and diversity of transporter systems in C. auris remain poorly defined. Through genomic analysis, we identified 686 transporters and 125 accessory factors involved in transport in C. auris, most of which had not been characterized. These transporters and accessory factors were classified into seven classes, 22 subclasses, and 215 families, reflecting substantial functional diversity. Comparative analyses with other pathogenic Candida species and Saccharomyces cerevisiae reveal lineage-specific divergence in several transporter families. We also integrated multiple publicly available RNA-seq datasets encompassing antifungal drug exposure and drug-resistant isolates and identified subsets of transporters that are transcriptionally responsive in distinct antifungal conditions, including members of families implicated in drug transport, metabolism, and ion homeostasis. Together, this study defines the landscape of transporter systems in C. auris and highlights transporter families that may contribute to stress adaptation and antifungal responses, providing a resource for future functional and mechanistic investigations.\n\nID: 41839671\nTitle: Astragalus membranaceus polysaccharide (APs) and Eugenol: Multi-target Anti-inflammatory, Antioxidant, Antimicrobial, and anticancer effects validated by in Silico studies.\nAbstract: Astragalus membranaceus is a traditional medicinal plant with diverse therapeutic properties largely attributed to its polysaccharides (APs). This study evaluated the antimicrobial, anti-inflammatory, antioxidant, and anticancer activities of APs and eugenol, both individually and in combination, against multidrug-resistant (MDR) pathogens and HepG2 liver cancer cells. Thirty bacterial and ten Candida isolates were recovered from skin abscesses, with five identified as MDR strains (Staphylococcus haemolyticus, S. aureus, E. coli, Acinetobacter baumannii, and Candida auris), confirmed by 16S rDNA and ITS sequencing. Both APs and eugenol exhibited marked antimicrobial activity, while their combination achieved the strongest inhibition (up to 27.3\u00a0\u00b1\u00a00.4\u00a0mm). C. auris was highly sensitive to APs alone (MIC: 2\u00a0\u00b1\u00a00.2\u00a0\u00b5g/mL). The combination also significantly downregulated IL-6, IL-17, and TNF-\u03b1 levels, and showed potent COX-2 inhibition (0.10\u00a0\u00b1\u00a00.01\u00a0\u00b5g/mL), surpassing celecoxib (0.9\u00a0\u00b1\u00a00.05\u00a0\u00b5g/mL). Antioxidant analysis (DPPH assay) revealed superior radical scavenging by the combination (57.5\u00a0\u00b1\u00a01.3\u00a0% %). Molecular docking confirmed the activity of eugenol, showing favorable binding to DNA gyrase B, sterol demethylase, COX-2, xanthine oxidase, and caspase-3, with the strongest affinity for xanthine oxidase (-5.25\u00a0kcal/mol). In anticancer assays, eugenol induced dose-dependent inhibition of HepG2 cell proliferation, while APs displayed limited cytotoxicity. Notably, the combination reduced cell viability to 3.77\u00a0\u00b1\u00a00.4\u00a0% % at 400\u00a0\u00b5g/mL, consistent with apoptotic changes. Collectively, these findings highlight the synergistic potential of APs and eugenol as a multi-target therapeutic approach against MDR infections, inflammation, oxidative stress, and liver cancer.\n\nID: 41817193\nTitle: Synergistic activity of caspofungin and posaconazole against Candida (Candidozyma) auris biofilms based on phenotypic, transcriptomic, and in vivo insights.\nAbstract: Candida (Candidozyma) auris is an emerging multidrug-resistant fungal pathogen capable of establishing persistent skin colonization, contaminating the environment, and causing nosocomial outbreaks associated with high mortality rates. Conventional monotherapy frequently proves inadequate against biofilm-associated infections, underscoring the urgent need for novel therapeutic strategies. Therefore, we investigated the physiological and molecular responses of South Asian clade C. auris biofilms to treatment with a caspofungin-posaconazole combination. This regimen markedly reduced the median minimum inhibitory concentrations (4- to 32-fold for caspofungin; 8- to 64-fold for posaconazole) compared with monotherapies. Synergistic interactions were observed in all isolates, with fractional inhibitory concentration indices ranging from 0.078 to 0.31, and were further confirmed in vivo. Transcriptomic profiling revealed activation of multiple stress-response pathways, driving adaptive changes such as enhanced extracellular matrix production and biofilm-forming capacity, maintenance of intracellular cation homeostasis, osmotic stress response, and extensive cell wall and membrane remodeling affecting the mannan-glucan complex, chitin, sphingolipids, phosphatidylinositol-(4,5)-bisphosphate, and ergosterol content. Additional responses included activation of RCT1 (fluconazole-inducible protein) and MDR1 (drug efflux pump), collectively promoting survival under combined antifungal pressure. These findings demonstrate the potent synergistic activity of caspofungin and posaconazole against C. auris biofilms, thereby supporting the development of effective combination therapies for this high-risk pathogen.IMPORTANCECandida auris is a rapidly emerging fungal pathogen that presents substantial challenges for infection control owing to its multidrug resistance, persistence in healthcare environments, and capacity to cause large-scale outbreaks. Biofilm formation on indwelling medical devices plays a pivotal role in C. auris outbreaks within healthcare settings and is implicated in nearly 90% of C. auris candidemia cases. These biofilms also exhibit pronounced tolerance to antifungal agents, thereby restricting available treatment options. Our study demonstrates that the combination of caspofungin and posaconazole exerts a strong synergistic effect against C. auris biofilms, both in vitro and in vivo. By elucidating the molecular mechanisms behind this synergy-including stress-response activation, cell wall and membrane remodeling, calcium signaling, and regulation of drug efflux pumps-this work provides important insights into antifungal therapeutic responses in C. auris and underscores combination therapy as a promising strategy to overcome biofilm-associated antifungal resistance in this high-risk pathogen.\n\nID: 41770595\nTitle: Antifungal activity of the antimicrobial peptide RP557 against priority fungal pathogens.\nAbstract: Background. Natural host defence molecules, part of innate immunity and the first line of defence, are evolutionarily conserved. Some pharmaceutical properties undesirable for clinical use led to the rational design of synthetic molecules with constructed peptide arrangements, giving a novel therapeutic avenue. A prior publication showed synthetic peptide RP557 inhibition and killing of fluconazole-sensitive and resistant Candida species isolates, biofilm inhibition, no resistance induction, direct membrane action, negligible mammalian cell toxicity and topical efficacy in a rodent vaginal candidiasis model. These findings highlight the relevance of investigating RP557 activity against other fungal pathogens.Objective. We evaluated the antifungal spectrum of the RP557 against World Health Organization-listed priority fungal pathogens, including endemic and skin fungal pathogens, both alone and in combination with commercial antifungal drugs.Methods. The antifungal spectrum was evaluated by broth dilution vs. clinical isolates, and we present 76 MICs (mcg ml-1) performed according to M27 or M38 CLSI documents, 35 checkerboard interactions with antifungals and 10 minimum fungicidal determinations.Results. Overall impression is robust activity vs. chromoblastomycosis and mycetoma species, Cryptococcus neoformans and Trichophyton spp.; broad MIC ranges within most species, least activity vs. Mucorales and Aspergillus spp.; and some promising drug interactions vs. Sporothrix spp. and Candida auris.Conclusion. Additional efficacy data in vivo is needed. Topical therapy could give local concentrations exceeding MICs, and burn or trauma prophylaxis or treatments are attractive potential targets owing to RP557 panmicrobial properties.\n\nID: 41768734\nTitle: Impact of Metal-Functionalized Fullerenes on the Proliferation of Pathogenic Fungi.\nAbstract: Given the trajectory and prevalence of multidrug-resistant (MDR) organisms like Candida auris, the dearth of available antifungal drugs and the global need for effective therapeutics, the exploration of safe antifungals with broad-spectrum potential and novel antimicrobial mechanisms is imperative for future treatment strategies. Herein, the broad-spectrum potential of previously synthesized silver and copper coordinated chlorine functionalized fullerene nanoparticles (Ag-C60-Cl and Cu-C60-Cl) against two clinically significant fungal pathogens, Candida albicans and C. auris is investigated. The experimental results show enhanced antifungal activity of Ag-C60-Cl compared to Cu-C60-Cl, C60-Cl, and fluconazole. The minimum inhibitory concentrations (MIC) of Ag-C60-Cl and Cu-C60-Cl are 15.62 and 250 \u03bcg/mL, respectively, against C. albicans. Notably, the MIC of the Ag-C60-Cl against C. auris is 3.9 \u03bcg/mL, whereas the MIC of Cu-C60-Cl is 250 \u03bcg/mL. Analysis of fungal growth kinetics shows that Ag-C60-Cl significantly delayed the growth of C. albicans and suppressed the growth of C. auris. Mechanistic studies highlight that Ag-C60-Cl produced higher reactive oxygen species (ROS) and triggered catalase enzymes by acting as oxidants. Additionally, the NPs exhibited physical interactions with yeast cells, indicating a dual mode of action. These findings establish the potential of Ag-C60-Cl as a new and potentially transformative antifungal strategy against two clinically significant pathogens.\n\nID: 41767947\nTitle: Profiling the host defense responses against Candida auris in a reliable Drosophila melanogaster infection model.\nAbstract: The \"superbug\" Candida auris has been ranked as a priority fungal pathogen and is becoming a serious threat to public health. However, the underlying mechanisms of real-world pathogen-host interactions remain elusive, in part due to the lack of powerful immunocompetent animal models. Here, we report that selected wild-type strains of Drosophila melanogaster can be developed as a promising infection model to recapitulate C. auris systemic infection. The systemic and organ-specific responses to C. auris infection in vivo were evaluated, as well as the corresponding transcriptional profiling. Our findings confirmed that Toll and JAK-STAT signaling pathways mediate antifungal responses in the Drosophila model following C. auris infection. Moreover, we identified certain conserved novel factors required for host-C. auris interactions, highlighting the fly model's potential to reveal subtle immune mechanisms not readily observed in mammalian systems. Taken together, our work demonstrates that wild-type Drosophila offers a robust immunocompetent animal model for further in-depth investigation of dynamic C. auris-host interactions in vivo.\n\nID: 41754774\nTitle: Unmasking the Fungicidal Potency and Multifaceted Mechanisms of Nutmeg Essential Oil Against Candida auris.\nAbstract: Background: Candida auris has emerged as a multidrug-resistant fungal pathogen, presenting significant clinical challenges worldwide. Although considerable progress has been made in antifungal research, the specific mechanisms underlying drug resistance in C. auris remain incompletely understood. To overcome this problem, natural compounds can be used as valuable alternatives. The present study aimed to evaluate the antifungal activity of NEO against C. auris and to understand the functional mechanisms underlying its antifungal activity. Methods: The antifungal activity of NEO against C. auris strain CBS10913T was examined using broth microdilution and spot assays to determine the minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC). Mechanistic investigations were performed using phenotypic-, biochemical-, and fluorescence-based assays to evaluate its effects on cell wall integrity, membrane permeability, efflux pump activity, oxidative stress, lipid peroxidation, biofilm formation, and host cell adherence. Hemolytic assays were performed to evaluate preliminary biocompatibility. Results: During our study, we found that NEO showed strong fungicidal activity against C. auris, with an MIC of 500 \u00b5g/mL and an MFC of 650 \u00b5g/mL, and disrupted fungal cell wall integrity, significantly reduced ergosterol content, and inhibited efflux pump activity, leading to increased accumulation of fluorescent substrates. NEO induced increased intracellular reactive oxygen species, leading to oxidative-mediated lipid peroxidation and DNA damage. Moreover, NEO also suppressed stress biofilm formation, reduced metabolic activity, and decreased adherence to buccal epithelial cells, and it showed negligible hemolytic activity up to 2\u00d7 MIC, indicating preliminary biocompatibility. Conclusions: This study demonstrates that NEO utilizes broad antifungal activity through multiple functional and phenotypic mechanisms, including disruption of membrane integrity, inhibition of efflux pump, induction of oxidative stress, and suppression of biofilm formation. Although the direct effects on pathogenicity-related genes or proteins were not studied, the findings still show NEO as a promising natural antifungal agent.\n\nID: 41745298\nTitle: Caspofungin Reshapes the Extracellular Vesicles Metabolome of Candidozyma (Candida) auris, Altering Amino Acid and Nucleotide Metabolism.\nAbstract: Candidozyma auris is an emerging multidrug-resistant fungal pathogen associated with severe invasive infections and high mortality, particularly in healthcare environments. Its rapid global expansion and resistance to multiple antifungal classes pose major challenges to treatment and containment. Extracellular vesicles (EVs) have recently been recognized as important mediators of fungal communication, virulence, and stress adaptation. Here, we examine how caspofungin, a frontline echinocandin, reshapes the EV metabolome of C. auris. Caspofungin exposure drives pronounced remodeling of EV size distributions, yielding a predominance of smaller, more uniform EVs alongside a minor population of larger subtypes. Metabolomic profiling of EVs revealed marked enrichment of metabolites involved in nucleotide salvage and recycling, along with altered amino acid abundances, including increases in amino acids associated with stress responses and redox regulation. These changes are consistent with altered nucleotide turnover and amino acid metabolism under antifungal stress. Importantly, these metabolic alterations reflect caspofungin-induced changes in cellular metabolism that are selectively exported via extracellular vesicles, rather than metabolic activity occurring within the vesicles themselves. Export of these metabolites via EVs may support population-level coordination, biofilm remodeling, and modulation of host immune responses, contributing to echinocandin tolerance. Together, our findings highlight nucleotide- and amino acid-associated metabolic features of EVs as informative readouts of caspofungin exposure and highlight the EV metabolome as a promising source of non-invasive biomarkers for monitoring drug exposure and resistance. This work advances understanding of C. auris adaptation under antifungal stress and reveals new opportunities for therapeutic and diagnostic innovation against this high-priority pathogen.\n\nID: 41745238\nTitle: Comprehensive Insights into Sugar Transporters of Candidozyma auris and Their Roles in Antifungal Resistance.\nAbstract: In Candida species, including Candidozyma auris (formerly Candida auris), overexpression of efflux pumps is a well-established mechanism of antifungal resistance. However, accumulating evidence indicates that impaired drug import may also significantly contribute to reduced antifungal susceptibility. Sugar importers, historically viewed solely as hexose transporters (HGTs), are now emerging as potential indirect modulators of antifungal uptake. Here, we performed a comprehensive inventory and functional analysis of the HGT family in C. auris to assess its contribution to antifungal import. Phylogenetic analyses revealed that C. auris HGTs are more closely related to those of Candida albicans (C. albicans) than Saccharomyces cerevisiae (S. cerevisiae). All HGT genes showed basal expression, with several significantly downregulated upon fluconazole (FLC) exposure. To establish functional relevance, we generated a mini-library of HGT deletion mutants. Notably, the \u0394hgt13 strain exhibited markedly increased FLC resistance, concomitant with reduced intracellular FLC accumulation and decreased membrane permeability. Consistently, molecular docking and molecular dynamics simulations demonstrated strong and stable interactions between FLC and Hgt13p. Together, these findings implicate Hgt13p as a key determinant of FLC import and membrane permeability, revealing reduced FLC import could also contribute to antifungal resistance in C. auris.\n\nID: 42141876\nTitle: Genomic landscape of Candidozyma auris in Italy, 2019 to 2025:\u2009emerging diversity of clade\u2009I sub-lineages associated with inter-facility transmission and cross-border transfers.\nAbstract: BACKGROUNDCandidozyma auris is a fungal pathogen of major concern, that frequently exhibits multidrug resistance and causes healthcare-related outbreaks worldwide. Italy experienced a large nosocomial outbreak in early 2020, with subsequent sporadic cases or small clusters in different regions.AIMTo provide an overview of the C. auris population structure, genomic diversity, and spread in Italy.METHODSGenome sequences from Italian C. auris isolates (n\u2009=\u200968) were obtained either from public databases, or by whole-genome sequencing of available isolates (n\u2009=\u200917) from previously uncharacterised and/or recently emerged (2025) cases. The sequence dataset was complemented with whole genome sequences of international isolates (n\u2009=\u2009139) to conduct a global phylogenetic analysis based on core-genome single nucleotide polymorphisms. Genetic mutations associated with antifungal resistance were investigated.RESULTSAll Italian isolates belonged to clade\u2009I (South Asian) but were interspersed among different subclades. Subclade\u2009Ic isolates were of a single lineage, characterised by the HMG1P238H mutation. This lineage spread over four regions. Subclade\u2009Ib members were more diverse, and associated with local or imported single cases, as well as nosocomial clusters following sporadic, independent C. auris introductions from countries in southern Europe. A putative new subclade (Id) was identified, involving isolates from Italy and an eastern European country. Subclades\u2009Ib-c-d exhibited lineage-specific genetic signatures in antifungal-resistance-associated loci (CDR1, ERG11, TAC1B).CONCLUSIONSIn Italy, C. auris strains form a complex population, resulting from emergence or evolution of clade\u2009I sub-lineages following, in some instances, sporadic introductions from other European countries. Strengthened screening protocols remain essential for inter-facility transfers and for patients with prior healthcare exposure abroad.\n\nID: 42003596\nTitle: Role of the transcription factor Wor2 in biofilm formation of Candidozyma auris.\nAbstract: The yeast pathogen Candidozyma (Candida) auris can form biofilms, which contribute to its virulence and nosocomial transmission. In this study, we identified the transcription factor Wor2 as a negative regulator of biofilm formation in C. auris. Wor2 hyperactivation in a strain of clade IV via the use of a protein tagging strategy resulted in downregulation of two important adhesins, SCF1 and ALS4112, and decreased biofilm-forming capacity. We showed that the impact on biofilm was predominantly mediated via decreased SCF1 expression in this strain. However, results of adhesion assays on inert surfaces and human keratinocytes found relatively modest roles of Wor2 and Scf1 in this process, suggesting that their effect on biofilm formation is complex and not limited to the adhesion step. Finally, analyses of other strains from different clades identified three distinct WOR2 genotypes, with variable WOR2 expression levels and distinct impacts of WOR2 deletion on biofilm formation. Notably, Wor2 negatively regulated biofilm in strains of clades I, III, and IV with distinct profiles of SCF1/ALS4112 expression, while it had no impact on biofilm in a clade II strain. Taken together, this study showed that Wor2 exhibited some distinct genotypic evolution in C. auris resulting in clade- or strain-specific regulatory roles and pathways in biofilm formation.IMPORTANCECandidozyma (Candida) auris is a pathogenic yeast exhibiting a particular capacity for interhuman transmission via medical instruments, which was the cause of nosocomial outbreaks of candidemia. Adhesion to inert surfaces and subsequent biofilm formation is therefore important for C. auris propagation. This work highlights the role of the transcription factor Wor2 as a negative regulator of biofilm formation in C. auris. In a strain of clade IV, Wor2 was shown to downregulate two important adhesins (SCF1 and ALS4112). Interestingly, Wor2 exhibited different genotypes across C. auris clades and strains, which were associated with distinct differential expression of WOR2, ALS4112, and SCF1, and possibly distinct roles in biofilm formation.\n\nID: 41912535\nTitle: Deep homology and design of proteasome chaperone proteins in Candidozyma auris.\nAbstract: A central tenet of biology is that protein structure mediates the sequence-function relationship. Recently, there has been excitement about the promise of advances in protein structure modeling to generate hypotheses about sequence-structure-function relationships. Here, we leverage structural similarity to identify rapidly evolving proteasome assembly chaperones and characterize their function in Candidozyma (Candida) auris. Despite extensive sequence divergence, we demonstrate conservation of function, corroborating that specific folds, and not sequences, are required for function. This theoretical premise suggests that protein structures with certain properties should be functionally interchangeable, even if they were not products of a common evolutionary history. To reduce this theory to practice, we performed structure-informed protein design, exploring sequence space that is not accessible via stepwise evolution, and mutated more than 40 residues in the Poc4 proteasome assembly chaperone to demonstrate that artificial proteins can rescue complex biological processes in the context of the whole cell. This sequence-structure-function relationship expands our ability to use structure to identify deep evolutionary relationships between proteins and generate hypotheses about gene function in non-model organisms. Overall, this helps to define and understand functional constraints on protein evolution, with important implications for both future protein design and retrospective function prediction.\n\n\n\nID: 41823412\nTitle: Candida auris metabolism and growth preferences in physiologically relevant skin-like conditions.\nAbstract: Candida auris is an opportunistic, multidrug-resistant yeast with a high capacity for human skin colonization in healthcare settings, which can lead to subsequent infections with high mortality rates. Despite the recent emergence of at least four distinct clades at the global scale, little remains known about how C. auris is so adept at growing on skin and the key genes and pathways it utilizes to metabolize the scarce nutrients available. Here, we identify the roles that conventional and alternative carbon metabolism genes and metabolic pathways have in facilitating C. auris growth through laboratory-based experiments and bioinformatics analyses. In artificial skin-like media, all four clades of C. auris were more capable of growing than Candida albicans SC5314, a clinically relevant counterpart. By investigating the differential regulation of C. auris when growing in skin-like media as compared to rich fungal media, we uncovered hundreds of genes in multiple metabolic pathways. To further test the mechanisms of these metabolic pathways, we deleted several non-essential gene candidates including FOX2 (B9J08_002847), CAT2 (B9J08_000010), and ICL1 (B9J08_003374). The mutant strains all exhibited abrogated growth in skin-like media and demonstrated nutrient preferences that differed from the wild type. Thus, we propose a model of how C. auris has the capacity to metabolize nutrients that are available on skin by optimizing its metabolic profile. Targeting these metabolic pathways to mitigate C. auris growth on skin is a potential avenue to explore in controlling the spread of this emerging human fungal pathogen. Candida auris is an emerging fungal pathogen with human skin as its primary site of colonization and subsequent transmission. Here, we show the importance of conventional and alternative carbon metabolism for the ability of C. auris to grow in artificial skin-like media. This knowledge provides a better understanding of C. auris metabolism and sheds light on genes and pathways that could be targeted to interfere with persistent skin colonization.\n\nID: 41745273\nTitle: Fatty Acid Profiling Identification Method of Emerging Fungal Pathogen Candidozyma auris (Formally Candida auris).\nAbstract: The species Candidozyma auris (formerly known as Candida auris) can be subdivided into four major and two minor clades. It is considered an emerging multidrug-resistant pathogen that causes invasive outbreaks around the world. Therefore, the accurate identification of this species plays an important role in combating invasion and facilitating pathogenic management. In our study an optional identification method was developed considering the possibility of using cellular fatty acids (FAs) as a taxonomic and diagnostic tool. FAs were recorded in the collected C. auris strains, and the species characteristic components were determined. Within the isolates examined, the clades were also separated in the statistical analysis. Furthermore, FAs from strains belonging to clade I and II have been divided into two distinct clusters. In testing the performance of the method, all identified samples showed good matches with the established C. auris record in the database without misreading. Taken together, cellular fatty acids were investigated as potential discriminatory biomarkers. The results suggest that this approach can distinguish C. auris from related species and provides distinctive fatty acid profiles for the investigated C. auris clades. The present findings revealed the first report on the application of whole cell FA components as taxonomic features in C. auris.\n\nID: 41703337\nTitle: Candida auris vacuolar calcium pump mediates fluconazole efflux and resistance evolution.\nAbstract: Candida auris is an emerging fungal pathogen notable for its intrinsically high resistance to fluconazole, the most prescribed antifungal drug. However, the genetic regulators underlying fluconazole susceptibility in C. auris remain unclear. Here we performed a pooled screen of piggyBac (PB) transposition mutants and identified significant enrichment of mitochondrial genes whose inactivation reduces fluconazole susceptibility. A genome-wide genetic interaction analysis of a mitochondrial gene deletion mutant, pet309\u0394, suggests that the vacuolar calcium pump homologue CDT1 (Calcium and Drug Transporter 1) is responsible for its reduced fluconazole susceptibility. Fluconazole induces significant upregulation of CDT1 through the calcineurin signalling pathway. Cdt1, beyond its canonical calcium-pumping function, has evolved another function in mediating fluconazole efflux through its fluconazole-induced, calcineurin- and ATP hydrolysis-dependent plasma membrane localization. In addition, Cdt1 accelerates the evolution of fluconazole resistance or tolerance, and its transcript levels are substantially elevated across resistant clinical isolates. Our findings reveal a neofunctionalized role for Cdt1 in mediating fluconazole efflux in C. auris.\n\nID: 41694172\nTitle: Denture-Associated Candidiasis and Mucormycosis in Post-COVID-19 Older Adults Managed Through an Integrated Prosthodontic and Infectious Disease Approach: A Narrative Review.\nAbstract: The COVID-19 pandemic has exposed significant vulnerabilities among older adults, particularly denture wearers, to opportunistic fungal infections, including mucormycosis and oral candidiasis. This narrative review, following PRISMA-ScR (Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Narrative Reviews) guidelines, collected evidence from 2020 to 2025 to examine the connection between denture use, systemic comorbidities, and fungal complications in elderly individuals after COVID-19. A total of 21 of 104 studies were included, covering case-control, cross-sectional, cohort, and retrospective studies from India, Europe, the Middle East, and North America.\u00a0Several studies have reported higher rates of oral fungal colonization among denture wearers,with\u00a0Candida albicans\u00a0being the most frequently isolated species, followed by resistant strains such as\u00a0Candida auris. However, these observations are primarily derived from heterogeneous observational studies and should therefore be interpreted as associative rather than causal. COVID-19-related mucormycosis (CAM) was primarily reported as rhino-orbito-cerebral disease, with oral manifestations including palatal necrosis, gingival ulcers, and tooth mobility. Key risk factors identified include diabetes mellitus, corticosteroid therapy, prolonged intensive care unit (ICU) stays, and poor denture hygiene. Mortality related to CAM ranged from 18% to 56%, while candidiasis, though less deadly, significantly affected oral function, nutrition, and overall quality of life. Diagnostic methods included clinical and intraoral examinations, microbiological cultures, imaging techniques, and emerging salivary biomarkers. Treatments included systemic antifungal medications, surgical removal, and prosthesis disinfection, highlighting the important role of prosthodontists in prevention and rehabilitation. Knowledge gaps remain regarding the predictive value of oral lesions for systemic infections, the long-term effects of COVID-19 on the oral microbiome, and the need to standardize denture hygiene protocols.\u00a0This review emphasizes the importance of integrated dental and medical care in reducing morbidity and mortality among denture-wearing older adults recovering from COVID-19, while recognizing that early oral findings may serve as warning indicators rather than definitive predictors of systemic infection.\n\nID: 41619989\nTitle: Antifungal and molecular analysis of gene expression caused by haloperidol in Candida spp.\nAbstract: Candidiasis, caused by yeasts of the Candida genus, is increasingly characterized by a high prevalence of clinical isolates resistant to conventional antifungals, rendering the development of novel therapeutic strategies paramount. Drug repurposing has emerged as a key strategy, utilizing established pharmaceuticals for indications beyond their original design; notably, haloperidol (HAL) has shown promising antimicrobial potential. In this context, the present study evaluates the activity of haloperidol, both as a monotherapy and in combination with conventional antifungals, against fluconazole-susceptible and fluconazole-resistant Candida spp. clinical strains. Furthermore, we investigate the underlying mechanisms of its antifungal action. Experimental approaches included broth microdilution assays to determine the Minimum Inhibitory Concentration (MIC), checkerboard assays for synergistic analysis, and cellular assessments via flow cytometry and fluorescence microscopy. Haloperidol displayed MIC values between 26.67 and 256\u202f\u03bcg/mL. Synergistic interactions were identified between haloperidol and the azoles fluconazole and itraconazole, alongside a 2.5\u202f% synergy rate with amphotericin B. Additionally, mechanistic assays confirmed that haloperidol induces programmed cell death (apoptosis) in C. albicans and C. auris strains. The oxidative stress caused by haloperidol altered Ca2+ homeostasis, followed by mitochondrial membrane depolarization, reduced ATP production, cytochrome c release into the cytosol and metacaspase activation, reduced viability, phosphatidylserine externalization, promoted fragmentation, damage and methylation of DNA. It also induced expression of genes related to oxidative stress. It reduced mitochondrial depolarization and decreased the reduction of glutathione (GSH), causing morphological alterations. The results suggest the apoptotic pathway as the main antifungal mechanism of haloperidol.\n\nID: 41565019\nTitle: From compliance to complexity: the impact of in vitro diagnostic regulation for clinical microbiology laboratories.\nAbstract: The implementation of the European in vitro medical devices regulation (IVDR) poses significant challenges, yet its impact has not previously been quantified in clinical microbiology. The aim of this study was to quantify the number of tests in a large clinical microbiology laboratory that may be affected by IVDR. The study was performed in a clinical microbiology laboratory of a large academic hospital in the Netherlands. We calculated proportion of CE-marked tests and laboratory-developed tests (LDTs), and we calculated the number of test results generated by these tests. We found that CE-IVD-labelled tests accounted for 55% (57/104) of the available tests in bacteriology but represented 82.8% (99 521/120 254) of all test results generated in this specialty. Among tests in mycology, 38% (6/16) were LDTs. Most LDTs were PCR assays targeting specific microorganisms, such as Bordetella spp. and Candida auris. In contrast, only 29% (7/24) of parasitology tests had a CE-IVD label, and these accounted for 38.3% (1612/4209) of all test results in this specialty. We showed the potential burden in complying with IVDR 2017/746 in a clinical microbiology laboratory and the need for LDTs in certain setting. The results of this study may initiate informed discussion on a balanced implementation of the IVDR, ensuring compliance while minimizing unnecessary burden for clinical microbiology laboratories and also manufacturers.\n\nID: 41436656\nTitle: Candida auris skin tropism and antifungal resistance are mediated by carbonic anhydrase Nce103.\nAbstract: The pronounced skin tropism and pan-antifungal resistance of Candida auris pose a serious global health threat. A key question in C. auris biology is how clinical isolates acquire amphotericin B resistance. Here we demonstrate that a carbonic sensing pathway (CSP) contributes to amphotericin B resistance by modulating mitochondrial energy functions in clinical C. auris isolates. Integrated transcriptomics and proteomics identify the carbonic anhydrase Nce103 and its transcription factors Rca1 and Efg1 as important regulatory components of the CSP. The conversion of CO2 into bicarbonate sustains energy metabolism required for colonization and fitness on human skin and in nutrient-limited microenvironments. We also show that bacterial skin colonizers engage urease to release CO2 that sustains C. auris fitness and skin colonization. These findings highlight therapeutic options to re-sensitize C. auris to antifungal treatments, as well as to prevent skin colonization by blocking the CSP.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

Phenotypically, the pathogen displays significant clade-dependent diversity, including variable biofilm formation, aggregation, and skin colonization capabilities.\n\n### [ABSTRACT & REWRITTEN CLAIM]\n*Candida auris* acts as a high-priority, multidrug-resistant fungal pathogen with complex regulatory mechanisms. Research identifies the importance of ergosterol biosynthesis, efflux pump activity (e.g., CDR1, MDR1), and mitochondrial adaptation (e.g., cytochrome bc1) in maintaining viability under antifungal pressure. Morphological plasticity, specifically the ability to transition between yeast, aggregative, and pseudohyphal forms, serves as a mechanism for immune evasion and environmental persistence.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe pathogenic profile of *Candida auris* is defined by its evolutionary divergence into distinct clades, each exhibiting unique molecular signatures and virulence traits. Its resistance to conventional antifungals\u2014including azoles, polyenes, and echinocandins\u2014is driven by both canonical point mutations (e.g., *ERG11* and *FKS1* mutations) and structural genomic variations such as segmental duplications. The ability of *C. auris* to persist in hospital settings is linked to its robust biofilm-forming capacity, regulated by transcription factors such as *WOR2*, and its unique skin-tropic behavior supported by specific carbon metabolism pathways and carbonic anhydrase activity. Host interaction is mediated by the suppression of neutrophil reactive nitrogen species and the exploitation of glucose-starvation-induced cell damage.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   The transcription factor *WOR2* acts as a negative regulator of biofilm formation; its inactivation is observed in clinical strains to enhance persistence.\n*   *Candida auris* suppresses host innate immune defenses by downregulating neutrophil reactive nitrogen species to below basal levels.\n*   The carbonic anhydrase *Nce103* is essential for maintaining fitness in nutrient-limited environments and sustaining amphotericin B resistance.\n*   Segmental duplications, rather than just point mutations, serve as a predominant, non-mutational driver of multidrug resistance.\n*   Extracellular vesicles (EVs) export metabolites linked to nucleotide salvage and amino acid metabolism, serving as a mechanism for population-level stress adaptation.\n*   *C. auris* exhibits \"morphotype-specific vulnerabilities,\" where transient developmental states (filamentous or pseudohyphal) represent entry points for peptide-based therapies.\n*   Nutrient limitation in the host environment triggers *NINJ1*-dependent macrophage lysis, facilitating fungal escape.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

NT-a9 is a novel triazole antifungal with potent activity against Candida and Cryptococcus species via strong inhibition of ergosterol biosynthesis. In vitro, NT-a9 exhibited potent and sustained antifungal activity against clinical isolates, with superior potency compared to fluconazole (FLC). It also displayed a prolonged post-antifungal effect (PAFE) against most Candida species, a property rarely seen in conventional azoles. Resistance profiling demonstrated that NT-a9 possesses a high genetic barrier, fully suppressing resistant mutant emergence in Cryptococcus species and maintaining stable susceptibility in Candida albicans during 28 days of continuous exposure. NT-a9 retained potent activity against FLC-resistant Cryptococcus neoformans and multidrug-resistant Candida auris, with minimal influence from drug efflux mechanisms. In murine invasive candidiasis, a single low dose of NT-a9 achieved 100% survival and markedly reduced renal fungal burden, significantly outperforming FLC. NT-a9 also substantially improved survival in mice infected with FLC-resistant C. auris. Mechanistically, NT-a9 binds Erg11 with much higher affinity than FLC by forming key hydrogen bonds with Gly307 and His377, leading to irreversible ergosterol depletion, toxic sterol accumulation, and severe fungal membrane damage. Transcriptomic analysis further confirmed that NT-a9 extensively disrupts sterol biosynthesis and triggers compensatory gene expression that reinforces its antifungal action. As a novel triazole integrating long-lasting efficacy, a high resistance barrier, and potent activity against pan-azole-resistant pathogens, NT-a9 represents a promising clinical candidate for treating IFIs."

Here, we investigated whether laboratory exposure of a clade III clinical C. auris isolate to TCZ could induce cross-resistance to clinical antifungals. Among 17 agrochemicals tested, only TCZ exhibited intrinsic antifungal activity. Brief (48 h) exposure to sub-MIC TCZ (1 \u03bcg/mL) selected variants (6.9% frequency) with cross-resistance to TCZ and fluconazole, but full susceptibility to caspofungin. Exposure to supra-MIC TCZ (8-32 \u03bcg/mL) produced three phenotypic classes: Class 2 (TCZ-R, fluconazole-R) and Class 3 (TCZ-R, fluconazole-R, plus tolerance to caspofungin and micafungin). The frequency of Class 3 increased dose-dependently from 23% to 50% as TCZ concentration rose. RNA-Seq revealed that both classes overexpressed MDR1, TAC1b, UPC2 and FKS1, but Class 2 showed broad ergosterol pathway upregulation, whereas Class 3 exhibited restricted ergosterol activation but downregulation of the sole chitinase gene CHT1 (5.17-fold), a known mechanism of echinocandin tolerance. Unlike the CRS-MIS phenomenon in Candida glabrata, our Class 3 adaptors displayed equal tolerance to both caspofungin and micafungin. Collectively, these findings demonstrate that, in a clade III clinical isolate of C. auris under the tested laboratory conditions, laboratory exposure to an agricultural triazole can rapidly select for clinically relevant azole cross-resistance and echinocandin tolerance in C. auris, suggesting that environmental fungicide use may inadvertently compromise the efficacy of last-line antifungals."

Specifically, it seeks to identify major gaps and challenges in Candidozyma auris (C. auris) classification, diagnostic methods, virulence traits, antifungal therapy, and infection prevention, thereby providing a consolidated evidence base to support improved clinical management, surveillance, and future research. Recent advances have enabled rapid, accurate identification of C. auris using updated MALDI-TOF MS databases and real-time PCR assays. Novel antifungal agents and combination therapies offer potential options against resistant and biofilm-forming C. auris, while recent studies of aggregation, biofilm formation and adhesion, and phenotypic switching have provided new insights into its virulence and persistence in healthcare settings. C. auris exhibits many virulence traits that influence the severity of its infections. Identifying C. auris using conventional microbiological and culture-based methods can be challenging, often leading to delayed diagnoses and inappropriate treatment\u00a0of infections. Its resistance to commonly used antifungal drugs, including azoles, polyenes and echinocandins, further complicates infection control and treatment strategies. C. auris strains are classified into six distinct clades: South Asia, East Asia, South Africa, South America, Iran and Singapore. Each clade exhibits unique genetic characteristics and varying levels of drug resistance. The emergence of C. auris underscores the high priority and urgent need for research, the development of practical molecular-based diagnostic tools, novel antifungal therapies, and robust infection control measures to combat this growing threat."

In this study, three clinical C. auris strains (namely C. auris strain 01, C. auris strain 03, and C. auris strain 13) with distinct origins were characterized to investigate their phenotypic variations and mechanisms of azole resistance. Comprehensive profiling revealed significant inter-strain differences in biofilm formation, cell surface hydrophobicity, adhesion capacity, and phospholipase activity. Testing for antifungal susceptibility showed that the three clinical strains exhibited different minimum inhibitory concentrations for multiple azoles (fluconazole, voriconazole, and itraconazole) and echinocandins (anidulafungin and micafungin). Sequencing identified Y132F mutations in the ERG11 gene of the three clinical strains. Mechanistic investigations demonstrated that fluconazole exposure significantly upregulated the expression of efflux pump genes (CDR1 and CDR2) and the genes encoding their transcriptional regulators (MDR1 and TAC1b). In a murine skin colonization model, comparing data from the standard strain C. auris strain CBS12766 and clinical strains of C. auris strain 03 and C. auris strain 13 exhibited a significantly higher fungal burden of tissue, whereas strain C. auris strain 01 showed an intermediate level. Host immunity response analysis revealed that expression of the IL-1\u03b2 gene was significantly elevated in C. auris strain CBS12766-infected mice, while expression of IL-6 and CXCL-1 genes was predominantly increased in the C. auris strain 01, with TNF-\u03b1 gene expression levels being comparable across all strains. Histopathological examination confirmed local infiltration of inflammatory cells and mild epidermal edema, indicating active host immune engagement. Overall, our findings highlighted substantial phenotypic heterogeneity, different colonization capacities, and differences in expression of inflammatory cytokines among the C. auris strains. Further investigations into fluconazole-response mechanisms identified enhanced efflux pump activity, along with ERG11 gene Y132F mutations and transcription factor modulation among these clinical strains."

However, the molecular mechanisms underlying its virulence remain incompletely understood. In this study, we performed in vivo transcriptome analysis using an immunosuppressed mouse gastrointestinal infection model to identify genes associated with host adaptation and virulence during infection. By comparing fungal transcriptomes obtained from colonization and dissemination sites with those from\u00a0in vitro cultures, we identified genes that were consistently upregulated during infection. Among these genes, the unfolded protein response regulator HAC1 was selected as a candidate virulence-associated gene for further analysis. Reverse transcription PCR and sequencing analyses revealed that\u00a0HAC1 mRNA in C. auris undergoes an unconventional splicing event of 287 bp that is enhanced under endoplasmic reticulum stress conditions. The excised region spans the annotated open reading frame boundary, suggesting that the translated region of\u00a0HAC1 may require re-evaluation. Notably, a proportion of HAC1 transcripts appeared to be spliced even under non-stress conditions, indicating a detectable basal level of the unfolded protein response. Differences in splicing dynamics were also observed among clade strains. Functional analyses demonstrated that deletion of\u00a0HAC1 increased sensitivity to endoplasmic reticulum stress. The HAC1 deletion mutant also exhibited reduced virulence in both Galleria mellonella and immunosuppressed mouse infection models, as evidenced by delayed host mortality and decreased fungal burdens, respectively. These findings indicate that HAC1 contributes to endoplasmic reticulum stress adaptation and survival in the host environment and identify\u00a0HAC1 as a virulence-associated gene in C. auris. Candida auris is an emerging multidrug-resistant fungal pathogen. Using in vivo transcriptome analysis, we identified HAC1 as a regulator of endoplasmic reticulum stress adaptation and virulence in infection models.

In this study, we employed a targeted drug-repurposing strategy to identify novel indications for existing FDA-approved compounds against C. auris, leading to the identification of Tavaborole as a potent fungistatic agent. Tavaborole displayed robust activity across all five tested clades of C. auris, as well as against Candida albicans and Candida glabrata. To investigate drug resistance mechanisms of C. auris, we applied quantitative proteomics analyses following exposure to Tavaborole and Amphotericin B (AmB), complemented by electron microscopy. Proteomic profiling revealed that C. auris mounts distinct but overlapping adaptive responses to antifungal stress, involving stress response pathways, metabolic reprogramming and amino acid biosynthesis. While Tavaborole primarily induced targeted stress adaptation, AmB triggered a broader, multi-pronged resistance response including oxidative stress mitigation, osmolyte production and metabolic remodeling. Shared alterations in glycogen metabolism and amino acid biosynthesis suggest conserved antifungal adaptation mechanisms. Altogether, this study highlights Tavaborole as a promising antifungal candidate against C. auris, sheds novel insights into drug resistance mechanisms employed by the pathogen and delivers a drug-repurposing procedure highly customizable to target other microorganisms."

This rapid expansion is defined by its unique population structure consisting of six distinct genomic clades with starkly different evolutionary trajectories, phenotypic traits, and clinical risks. We conducted a systematic synthesis of literature from PubMed, Scopus, and Google Scholar (2009-2026), focusing on comparative genomics, clade-specific virulence, and diagnostic accuracy. A total of 64 studies were analyzed to identify patterns in clade divergence and antifungal resistance. Our analysis reveals that C. auris is not a monolithic threat but a complex of diverse lineages with specialized adaptations. Clade I (South Asian) and Clade IV (South American) represent the highest clinical risk due to hyper-virulence and high rates of multi-drug resistant (MDR) strains. In contrast, Clade II (East Asian) was initially associated with localized ear infections; recent genomic data show an expanding pathogenic profile with emerging bloodstream infections. Our review also identifies Clade V (Iranian) as a genetically distinct group and highlights the recent identification of Clade VI (Indomalayan) as a distinct lineage, suggesting a long-standing environmental reservoir. Furthermore, we identify critical \"blind spots\" in automated diagnostic platforms (VITEK\u00ae 2, BD Phoenix) where phenotypic variations in Clades II and III lead to frequent misidentification as Candida haemulonii or Candida famata. This review proposes a \"clade-aware\" framework for public health. While frontline antifungal treatment remains standardized regardless of lineage, we argue that effective long-term management and outbreak containment require integrating genomic surveillance with clade-specific infection control. By identifying high-biofilm clades (Clade I) or hyper-virulent lineages (Clade IV), public health systems can implement more targeted containment strategies, moving toward a precision-based approach to managing this fungal pathogen."

In recent years, these pathogens have increasingly been reported beyond traditional hospital settings, including neonatal intensive care units, long-term care facilities, oncology wards, and post-pandemic critical care environments. International surveillance bodies, including the Centers for Disease Control and Prevention (CDC), European Centre for Disease Prevention and Control (ECDC), World Health Organization (WHO), and regional monitoring networks, have documented escalating antifungal resistance, complex outbreak dynamics, and persistent gaps in infection control implementation. C. auris has emerged as a major etiological agent of healthcare-associated outbreaks, particularly in intensive care and neonatal units. Surveillance data indicate that a high proportion of C. auris isolates exhibit resistance to azoles, often exceeding 80% in some regions, while echinocandin resistance remains variable. Resistance patterns have evolved from predominantly azole resistance to broader multidrug-resistant phenotypes, including treatment-emergent echinocandin resistance. Six genetically distinct clades (I-VI) have been identified, with Clades I, III, and IV associated with large-scale outbreaks, whereas available data suggests that Clades II, V, and VI are more geographically restricted, although evidence for the recently described clades remains limited. C. glabrata is increasingly recognized as a major cause of invasive candidiasis, with rising resistance reported across multiple regions. While reduced azole susceptibility was historically predominant, emerging evidence highlights rising dual azole-echinocandin resistance, adaptive microevolution during antifungal therapy, and biofilm-associated tolerance mechanisms. Despite these advances, significant gaps persist in global resistance surveillance and in the mechanistic understanding of virulence and antifungal adaptation. Current mitigation strategies include antifungal stewardship programs, expanded resistance testing, and strengthened surveillance systems. Advances in rapid diagnostic technologies such as matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry, polymerase chain reaction (PCR)-based assays, and genomic surveillance have improved pathogen identification and outbreak detection, although accessibility remains limited in resource-constrained settings. This review examines emerging epidemiological, genomic, and antifungal resistance trends in C. auris and C. glabrata and highlights key priorities for improving diagnosis, surveillance, stewardship, and management of multidrug-resistant Candida infections."

Data from T\u00fcrkiye remains limited. This retrospective observational study evaluated bacterial and fungal isolates from adult ICU patients at a tertiary hospital from 2016 to 2025. Microorganisms were identified, and antimicrobial susceptibility testing was performed using standardized methods. Resistance patterns were compared between the pre-pandemic (January 2016-February 2020) and post-pandemic (March 2020-May 2025) periods. A total of 2666 patients and 5433 isolates were analyzed. Gram-negative pathogens showed marked increases in resistance: carbapenem and colistin resistance in Klebsiella pneumoniae were significantly higher in the post-pandemic period (69.6% vs. 44.4% and 60.5% vs. 22.5%, respectively; p < 0.001). Resistance rates to multiple antimicrobial agents also increased in Acinetobacter baumannii and Pseudomonas aeruginosa (p < 0.05). Among Gram-positive bacteria, vancomycin-resistant Enterococcus faecium increased from 10% to 47.1%. Candida auris emerged only in the post-pandemic period, showing high resistance to fluconazole (75%) and amphotericin B (36.7%). Significant differences in AMR patterns were observed between the pre- and post-pandemic periods in this ICU population. Higher resistance rates were observed among several clinically important bacterial pathogens, and Candida auris emerged exclusively during the post-pandemic period. Given the study's observational design, these findings should be interpreted as temporal associations rather than evidence of a causal effect of the COVID-19 pandemic. Continued antimicrobial stewardship and infection-control measures remain essential to address the growing burden of AMR."

Although antifungal therapy is standard, the host pathways shaping vascular responses-particularly the Notch signaling pathway (NSP)-are not well characterized in this context. In addition, the potential influence of the prostaglandin pathway on vascular NSP-related responses during infection remains unclear. In this study, a rat model of central venous catheter-associated C. albicans infection was used to evaluate microbiological outcomes and vascular NSP-related protein expression. Immunohistochemical analyses were performed to assess Candida immunostaining alongside the expression of Notch receptors (Notch1-3) and ligands (DLL1/4, Jagged1/2) in vascular tissues. Experimental groups included sham, infected control, antifungal-treated (fluconazole, caspofungin, liposomal amphotericin B), and prostaglandin pathway-intervention groups (sulprostone and sulprostone followed by indomethacin). C. albicans infection was associated with higher vascular NSP-related protein expression compared with sham animals. Antifungal-treated groups showed lower NSP-related protein expression, while fungicidal agents were associated with absence of fungal growth in catheter and kidney cultures. In the sulprostone-indomethacin-treated group, NSP-related protein expression levels were lower than those in the sulprostone-treated group despite persistent fungal burden. In conclusion, central venous catheter-associated C. albicans infection was associated with altered vascular NSP-related protein expression. Differences in NSP-related protein expression patterns were observed across antifungal- and prostaglandin pathway-intervention groups. These findings are descriptive and do not allow causal inference but may provide a basis for future studies exploring the role of NSP in vascular responses to C. albicans infection."

A systematic review.\nAbstract: Candida auris is a widely distributed yeast that is considered a dangerous pathogen, with reported mortality rates ranging from 30% to 60%. This yeast shows a high level of resistance to several antifungal agents commonly used to treat systemic infections. The pathogen persists on contaminated surfaces, tolerates hospital-grade disinfectants, survives desiccation and spreads easily through direct or indirect contact. It has been reported on all five continents and is increasingly prevalent in Europe. To determine the distribution and antifungal susceptibility/resistance of Candida auris isolates identified in Europe until January 2025. This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Searches were conducted in EBSCOhost, MEDLINE/PubMed, Scopus and SciELO databases using the terms 'Candida auris' and 'Candidozyma auris', combined with the name of each European country. It was limited to English or Spanish articles published until 31 January 2025, excluding reviews, meta-analyses and book chapters. Ninety-one articles reporting antifungal susceptibility were retrieved, covering 2191 clinical isolates of C.\u2009auris from 16 countries. Most isolates were from Spain (n\u2009=\u2009886, 40.44%), Italy (n\u2009=\u2009553, 25.24%), Greece (n\u2009=\u2009214, 9.77%), the United Kingdom (n\u2009=\u2009182, 8.31%) and Russia (n\u2009=\u2009108, 4.93%), accounting for 88.68% of cases. The remaining 248 isolates (11.32%) were reported across 11 other countries. Fluconazole resistance was found in 90.51% (1555/1718), while resistance to amphotericin B and echinocandins was 13.17% (223/1693) and 4.57% (76/1693), respectively.

Here, we integrate pangenomic analysis with global essentiality screening to establish a foundational understanding of the C. auris genome and identify potential therapeutic targets. We performed pangenome analysis on 695 outbreak strains of C. auris selected to be genetically representative of publicly sequenced genomes. After using BLAST to refine the pangenome, we found that 96.8% of gene families were core, with the remaining high-confidence accessory gene families primarily consisting of gene loss events or clade-specific genes. The high proportion of core genes emphasizes the clonal nature of these outbreak strains, but comparative analysis with the closely related C. haemuli species complex suggested that most of these core genes are functionally dispensible. To examine this hypothesis, we developed a novel insertional mutagenesis approach that leverages the promiscuous integration of linear DNA in the C. auris genome. This global analysis identified 614 high-confidence essential genes. Crucially, nearly one-third of these genes, including the conserved translation initiation factor Sui1, exhibit divergent essentiality patterns compared to the model yeasts Candida albicans and Saccharomyces cerevisiae. These findings highlight organism-specific biology that would be overlooked by orthology alone. By combining pangenomic diversity with functional essentiality, this study provides a comprehensive resource for identifying species-specific determinants of virulence and prioritizing novel targets for antifungal drug development."

Pronounced drug resistance makes treatment failure common, and so does antifungal tolerance, a phenomenon enabling pathogen survival at supra-MIC concentrations without resistance mutations. Here, we uncover a mechanism of antifungal tolerance in C. auris engaging the mitochondrial cytochrome bc1 complex. Deletion of RIP1, a conserved catalytic complex subunit, does not significantly alter the susceptibility to caspofungin or voriconazole. However, rip1\u0394 mutants exhibit a marked reduction in antifungal tolerance across a wide range of supra-MIC concentrations. Transcriptomics reveals the dysregulation of multiple drug resistance and tolerance-related genes in the rip1\u0394 mutant, demonstrating a role for Rip1 in controlling antifungal susceptibility. Targeting cytochrome bc1 function with the fungal-specific inhibitor Inz-5 enhances antifungal action of both voriconazole and caspofungin. Additionally, ablation of RIP1 causes fitness defects, suggesting that cytochrome bc1 is a potential antifungal target against C. auris infections."

C. auris can cause invasive infections associated with high mortality and can colonize patients asymptomatically, which facilitates transmission in health care settings. Since it was first reported in the United States in 2016, C. auris has been identified in multiple states, with increasing numbers of cases reported annually. Monitoring national trends in cases identified through clinical testing and screening for colonization is critical to guide infection prevention and control efforts. 2022-2024. State and jurisdictional health departments voluntarily report clinical and screening C. auris cases to CDC using standardized case definitions of the Council of State and Territorial Epidemiologists. Clinical cases are defined as detection of C. auris from specimens collected for diagnostic purposes; screening cases are defined as detection from colonization screening swabs. Cases were reported to CDC through the Research Electronic Data Capture (REDCap) or Data Collation and Integration for Public Health Event Response (DCIPHER) platforms. Data included patient age and sex, case type, specimen type (for clinical cases), health care facility type, Antimicrobial Resistance Laboratory Network geographic region, and specimen collection date. Analyses were descriptive and limited to cases with specimens collected during 2022-2024. During 2022-2024, a total of 13,507 clinical C. auris cases were reported to CDC, increasing from 2,882 in 2022 to 4,428 in 2023 and 6,197 in 2024, with smaller annual percentage increases over time (53.7% from 2022 to 2023 and 39.9% from 2023 to 2024). Most clinical cases occurred among adults aged \u226545 years (87.8%) and among males (61.0%). The most common specimen types among all clinical cases were urine (31.5%) and blood (30.2%); by year, the proportion of blood as the specimen type was 34.4% in 2022, 30.2% in 2023, and 25.6% in 2024. Most clinical cases were identified through specimens collected in acute care hospitals (76.6%) and long-term acute care hospitals (17.8%).During the same period, a total of 27,853 screening cases were reported to CDC, increasing from 6,226 in 2022 to 9,195 in 2023 and 12,432 in 2024. Screening cases most frequently occurred among adults aged \u226545 years (90.0%) and males (57.9%). Among cases with known facility type, the proportion of specimens collected in acute care hospitals increased from 24.7% in 2022 to 50.7% in 2024, whereas the proportion of specimens collected in long-term acute care hospitals decreased from 56.1% to 35.7% during the same period. The number of clinical and screening C. auris cases reported to CDC increased during 2022-2024, indicating ongoing transmission in U.S. health care settings. Although annual percentage increases in clinical cases declined over time, absolute case counts reported to CDC continued to rise. The increasing proportion of screening cases with specimens collected in acute care hospitals might reflect increased use of screening in acute care hospitals, including screening at admission. Because of increases in the number of reported C. auris cases, sustained infection prevention and control efforts in health care facilities, including adherence to transmission-based precautions, environmental disinfection with agents effective against C. auris, and communication of C. auris status during patient transfers remain essential to preventing clinical infections and colonization. Because this pathogen is frequently resistant to antifungal drugs, continued investment in laboratory capacity and surveillance, including antifungal susceptibility testing and screening of patients at high risk for C. auris infection, can support timely detection and guide prevention strategies. Ongoing public health coordination at federal, state, and local levels is critical to limit further spread and to address emerging antifungal drug resistance."

We investigated seven C. viswanathii isolates overall, including three recovered at our institution from blood, urine, and bronchoalveolar lavage of a NICU patient, as well as four bloodstream isolates from a second pediatric center included for comparison. Isolates were analyzed by culture and microscopy, three MALDI-TOF MS platforms, internal transcribed spacer sequencing, Fourier transform infrared (FTIR) spectroscopy and antifungal susceptibility testing. C. viswanathii was repeatedly recovered from blood, urine and bronchoalveolar lavage, while the FilmArray BCID2 panel remained negative. All MALDI-TOF MS systems with updated databases correctly identified the yeast at the species level; identification was confirmed by sequencing. Fourier transform infrared analysis showed clustering of clinical isolates and clearly separated C. viswanathii from related Candida species. All isolates exhibited low MICs to echinocandins and amphotericin B as well as moderately elevated fluconazole MICs (2-4 mg/L). This study supports the use of explicit diagnostic algorithms for rare fungal pathogens in yeast-positive, syndromic panel-negative blood cultures.

Its biological success is rooted in a robust, multi-faceted adaptive capacity. Recent molecular research identifies distinct genomic strategies employed by the pathogen to navigate therapeutic pressure. Specifically, structural variations, such as those within the ERG11 locus, drive azole resistance, while supernumerary chromosomes contribute to echinocandin tolerance. Furthermore, internal regulatory systems, including the unfolded protein response and specific mitochondrial complexes, enable C. auris to maintain viability under host-imposed stress. The pathogen\u2019s ability to manipulate the host immune environment\u2014specifically by suppressing reactive nitrogen species\u2014underscores its sophisticated virulence. Surveillance data indicate that environmental reservoirs and hospital-associated colonization remain primary drivers of dissemination.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   C. auris employs non-mutational mechanisms of resistance, specifically segmental duplications of genomic regions, to circumvent antifungal activity.\n*   The pathogen displays clade-specific geographic distribution and resistance profiles, complicating universal treatment protocols.\n*   C. auris can persist on non-living environmental surfaces and skin, exhibiting tolerance to standard hospital disinfectants.\n*   A significant proportion of the C. auris genome consists of core gene families, yet many are functionally dispensable under experimental conditions.\n*   C. auris exhibits a unique ability to manipulate host neutrophil responses by suppressing reactive nitrogen species (RNS) production.\n*   Environmental surveillance has detected C. auris DNA in surface waters, indicating potential reservoirs outside traditional clinical settings.\n*   Cross-kingdom interactions (e.g., mycoviruses) and abiotic stress may influence the thermal tolerance and fitness of the pathogen.\n*   Phenotypic variation in C. auris frequently results in misidentification by standard diagnostic automated systems, often being mislabeled as other yeast species.\n*   Early morphogenetic states of C. auris represent a transient vulnerability to specific antifungal proteins.\n*   The metabolic regulation by mitochondrial proteins is critical for tolerance, with specific deletions leading to fitness defects.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

NT-a9 is a novel triazole antifungal with potent activity against Candida and Cryptococcus species via strong inhibition of ergosterol biosynthesis. In vitro, NT-a9 exhibited potent and sustained antifungal activity against clinical isolates, with superior potency compared to fluconazole (FLC). It also displayed a prolonged post-antifungal effect (PAFE) against most Candida species, a property rarely seen in conventional azoles. Resistance profiling demonstrated that NT-a9 possesses a high genetic barrier, fully suppressing resistant mutant emergence in Cryptococcus species and maintaining stable susceptibility in Candida albicans during 28 days of continuous exposure. NT-a9 retained potent activity against FLC-resistant Cryptococcus neoformans and multidrug-resistant Candida auris, with minimal influence from drug efflux mechanisms. In murine invasive candidiasis, a single low dose of NT-a9 achieved 100% survival and markedly reduced renal fungal burden, significantly outperforming FLC. NT-a9 also substantially improved survival in mice infected with FLC-resistant C. auris. Mechanistically, NT-a9 binds Erg11 with much higher affinity than FLC by forming key hydrogen bonds with Gly307 and His377, leading to irreversible ergosterol depletion, toxic sterol accumulation, and severe fungal membrane damage. Transcriptomic analysis further confirmed that NT-a9 extensively disrupts sterol biosynthesis and triggers compensatory gene expression that reinforces its antifungal action. As a novel triazole integrating long-lasting efficacy, a high resistance barrier, and potent activity against pan-azole-resistant pathogens, NT-a9 represents a promising clinical candidate for treating IFIs.\n\nID: 42549922\nTitle: Baicalein suppresses adhesion and biofilm formation in Candida auris.\nAbstract: Candida auris, an emerging multidrug-resistant fungal pathogen, poses a severe global public health threat owing to its high nosocomial transmissibility, considerable mortality, and widespread antifungal resistance. Baicalein (BE), a major bioactive constituent of Scutellaria baicalensis Georgi, exhibits notable antifungal potential, yet its specific molecular mechanisms against C. auris remain poorly elucidated. In this study, we determined the antifungal activity of BE against multiple C. auris isolates, assessed its effects on fungal growth, virulence attributes, adhesion, and biofilm development, validated its in vivo protective efficacy in a Galleria mellonella infection model, and explored the underlying mechanisms via transcriptomic sequencing. BE exerted potent and consistent antifungal activity against all tested strains, with a minimum inhibitory concentration of 1 \u03bcg/mL, minimum fungicidal concentrations of 4-8 \u03bcg/mL, and a sessile minimum inhibitory concentration of 32 \u03bcg/mL. It time- and concentration-dependently suppressed fungal growth, virulence factor expression, adhesion to biological and non-biological surfaces, and biofilm formation, while conferring significant in vivo protection against C. auris infection. Transcriptomic analysis identified 11 adhesion- and biofilm-associated target genes, among which SCF1 and ALS1 served as pivotal regulators. Collectively, BE exerts robust anti-C. auris effects by modulating key target gene expression to interfere with multiple virulence-related processes, providing experimental support for its development as a novel antifungal agent for C. auris infection treatment.IMPORTANCEThe emerging multidrug-resistant fungal pathogen Candida auris has become a critical global public health concern. Its pronounced nosocomial transmissibility, high infection-associated mortality, and extensive cross-resistance to mainstream antifungal agents have created substantial unmet needs in clinical treatment and nosocomial infection control. In this study, we systematically validated the in vitro and in vivo antifungal activity of baicalein against C. auris and elucidated the molecular mechanism underlying its modulation of virulence-related genes. Our findings provide a pivotal experimental basis for the development of novel antifungal therapeutics targeting C. auris infections.\n\nID: 42548967\nTitle: Qdr3 Coordinates cellular homeostasis, mitochondrial remodeling, and virulence in Candidozyma auris (Candida auris).\nAbstract: Qdr3 acts as a global regulator in Candidozyma auris (Candida auris), coordinating mitochondrial function and cell-surface architecture.

Here, we investigated whether laboratory exposure of a clade III clinical C. auris isolate to TCZ could induce cross-resistance to clinical antifungals. Among 17 agrochemicals tested, only TCZ exhibited intrinsic antifungal activity. Brief (48 h) exposure to sub-MIC TCZ (1 \u03bcg/mL) selected variants (6.9% frequency) with cross-resistance to TCZ and fluconazole, but full susceptibility to caspofungin. Exposure to supra-MIC TCZ (8-32 \u03bcg/mL) produced three phenotypic classes: Class 2 (TCZ-R, fluconazole-R) and Class 3 (TCZ-R, fluconazole-R, plus tolerance to caspofungin and micafungin). The frequency of Class 3 increased dose-dependently from 23% to 50% as TCZ concentration rose. RNA-Seq revealed that both classes overexpressed MDR1, TAC1b, UPC2 and FKS1, but Class 2 showed broad ergosterol pathway upregulation, whereas Class 3 exhibited restricted ergosterol activation but downregulation of the sole chitinase gene CHT1 (5.17-fold), a known mechanism of echinocandin tolerance. Unlike the CRS-MIS phenomenon in Candida glabrata, our Class 3 adaptors displayed equal tolerance to both caspofungin and micafungin. Collectively, these findings demonstrate that, in a clade III clinical isolate of C. auris under the tested laboratory conditions, laboratory exposure to an agricultural triazole can rapidly select for clinically relevant azole cross-resistance and echinocandin tolerance in C. auris, suggesting that environmental fungicide use may inadvertently compromise the efficacy of last-line antifungals.\n\nID: 42545748\nTitle: Candida auris: An opportunistic fungal pathogen and a priority emergent threat.\nAbstract: Candida auris is an opportunistic yeast causing infections in vulnerable patients leading to high mortality ratio. The Centers for Disease Control and Prevention (CDC) has designated it as a pathogen of concern. The World Health Organization (WHO) has listed it in priority list of fungal pathogens. C.\u00a0auris has the ability to spread very fast inside the hospital environment and cause outbreaks worldwide. It has a very high affinity toward skin colonization, especially in the areas like axilla and groin. Based on whole genome sequencing it is classified into five clades. Each clade has different geographical distribution. Often C. auris gets misidentified as other species due to its phylogenetic similarity with C.\u00a0heamulonii. This can only be resolved by establishing diagnosis at molecular levels. Whole genome sequencing and polymerase chain reaction are some of the important molecular diagnostic methods for detection of C. auris. MALDI-TOF-MS is a culture based highly efficient method that is widely being used for C. auris identification. Treatment of C. auris infection depends on effective antifungal therapy, as multidrug resistance is quite common, the drug regime is decided after antifungal sensitivity testing. It is commonly treated with echinocandins and polyenes. Apart from the antifungal therapy it is also important to monitor the fungemia by performing blood cultures. A strict surveillance system can help prevent the disease. Timely screening of hospital personnel carrying the yeast can contain the spread of this organism. Newer antifungal agents are also required as the organism develops resistance very fast.\n\nID: 42541938\nTitle: The potential of bacteriocins in invasive fungal infections: Antifungal activities and intestinal protection.\nAbstract: Invasive fungal infections are life-threatening complications in immunocompromised and critically ill patients. Invasive candidiasis may arise from endogenous fungal reservoirs, particularly under conditions of intestinal barrier disruption. Although conventional antifungal agents remain the therapeutic foundation, their clinical use is increasingly challenged by the emergence of resistant fungal pathogens, such as Candida auris. Bacteriocins are ribosomally synthesized antimicrobial peptides produced by microorganisms. Beyond their well-established applications in the food industry, bacteriocins have attracted increasing attention in recent years for their antifungal properties. In this review, we provide an overview of bacteriocins with reported antifungal activity and summarize their underlying mechanisms. In addition, we discuss the potential protective effects of bacteriocins on the microbial, mechanical, chemical, and immune barriers of the intestine. Finally, we evaluate the potential clinical applications of these bacteriocins, along with future challenges and research directions related to invasive fungal infections.\n\nID: 42537628\nTitle: Pathogenicity and virulence of Candida auris.\nAbstract: Candida auris (Candidozyma auris) has emerged as a multidrug\u2011resistant human fungal pathogen that causes infections of high morbidity and mortality. Notably, it exhibits a unique ability to grow and persist on human skin, thus leading to efficient transmission through skin-to-skin contact. As a result, C. auris poses a significant risk of outbreaks in healthcare settings, especially in nursing homes that care for elderly patients. Most concerning, C. auris clinical isolates demonstrate widespread and, in some cases, untreatable resistance to all antifungal drug classes, including azoles, polyenes (amphotericin B), and echinocandins. Consequently, invasive C. auris infections cause high mortality rates (30-60%) even with antifungal therapy. Here, we provide a comprehensive overview of candidiasis caused by C. auris, discussing both host and pathogen determinants of skin colonization, as well as key challenges associated with preventing dissemination and management of disseminated fungal infections.\n\nID: 42530613\nTitle: Cytochrome bc1 Catalytic Subunit Rip1 Modulates Antifungal Tolerance in Candida auris.\nAbstract: Candida auris is an emerging fungal pathogen causing invasive infections in immunocompromised patients, with mortality rates reaching up to 60%. Pronounced drug resistance makes treatment failure common, and so does antifungal tolerance, a phenomenon enabling pathogen survival at supra-MIC concentrations without resistance mutations. Here, we uncover a mechanism of antifungal tolerance in C. auris engaging the mitochondrial cytochrome bc1 complex. Deletion of RIP1, a conserved catalytic complex subunit, does not significantly alter the susceptibility to caspofungin or voriconazole. However, rip1\u0394 mutants exhibit a marked reduction in antifungal tolerance across a wide range of supra-MIC concentrations. Transcriptomics reveals the dysregulation of multiple drug resistance and tolerance-related genes in the rip1\u0394 mutant, demonstrating a role for Rip1 in controlling antifungal susceptibility. Targeting cytochrome bc1 function with the fungal-specific inhibitor Inz-5 enhances antifungal action of both voriconazole and caspofungin. Additionally, ablation of RIP1 causes fitness defects, suggesting that cytochrome bc1 is a potential antifungal target against C. auris infections.\n\nID: 42527656\nTitle: The urgent and challenging superbug fungus Candidozyma auris (formerly Candida auris): a comprehensive review.\nAbstract: Based on recent literature, this review critically summarises current information on Candidozyma auris (formerly known as Candida auris) infections to identify factors contributing to their emergence and persistence in healthcare settings. Specifically, it seeks to identify major gaps and challenges in Candidozyma auris (C. auris) classification, diagnostic methods, virulence traits, antifungal therapy, and infection prevention, thereby providing a consolidated evidence base to support improved clinical management, surveillance, and future research. Recent advances have enabled rapid, accurate identification of C. auris using updated MALDI-TOF MS databases and real-time PCR assays. Novel antifungal agents and combination therapies offer potential options against resistant and biofilm-forming C. auris, while recent studies of aggregation, biofilm formation and adhesion, and phenotypic switching have provided new insights into its virulence and persistence in healthcare settings. C. auris exhibits many virulence traits that influence the severity of its infections. Identifying C. auris using conventional microbiological and culture-based methods can be challenging, often leading to delayed diagnoses and inappropriate treatment\u00a0of infections. Its resistance to commonly used antifungal drugs, including azoles, polyenes and echinocandins, further complicates infection control and treatment strategies. C. auris strains are classified into six distinct clades: South Asia, East Asia, South Africa, South America, Iran and Singapore. Each clade exhibits unique genetic characteristics and varying levels of drug resistance. The emergence of C. auris underscores the high priority and urgent need for research, the development of practical molecular-based diagnostic tools, novel antifungal therapies, and robust infection control measures to combat this growing threat.\n\nID: 42522315\nTitle: Phytochemicals as Novel Antifungal Agents Against Candida species.\nAbstract: Infections caused by Candida, including vulvovaginal candidiasis (VVC) and invasive candidiasis (IC), are a growing public health problem, exacerbated by multidrug resistance, biofilm persistence, and the limited development of antifungal drugs. In this review, we discuss plant-derived natural products with potent anti-Candida activity, specifically terpenoids, alkaloids, flavonoids, phenolics, and their nanoformulations. Many compounds, including berberine, artemisinin, thymol, eugenol, carvacrol, quercetin, catechins, lawsone, and caffeic acid, have shown the ability to modulate the fundamental mechanisms of fungal growth, which include disrupting membranes, inhibiting ergosterol biosynthesis, modulating efflux pumps, inducing oxidative stress, and biofilm inhibition. Some phytochemicals also demonstrate synergism with azoles, polyenes, and echinocandins, which can support dose reduction and restoration of resistance. Ultimately, while there is supportive preclinical evidence for anti-Candida action via the aforementioned compounds, clinical translation has been limited due to issues concerning standardization of use, pharmacokinetic variability, and toxicity issues. Some recent advances in nano-delivery systems, structural bioactivity modifications, and molecular docking studies provide a path forward when considering ways to maximize antifungal properties and improve bioavailability. This review highlights current advancements, therapeutic opportunities, and critical research gaps to accelerate the integration of phytochemicals into antifungal stewardship and device-associated infection control strategies.\n\nID: 42519068\nTitle: Guar gum-quercetin bioconjugate as a promising multifunctional biomaterial for combating drug-resistant fungal pathogens.\nAbstract: The global emergence of Candida auris, a multidrug-resistant fungal pathogen associated with high transmissibility and limited therapeutic options, highlights the need for new antifungal strategies. In this study, we report the synthesis, characterization, and biological evaluation of a guar gum-quercetin bioconjugate designed to improve the practical applicability of quercetin through covalent conjugation with a biocompatible polysaccharide scaffold and a cystamine-based disulfide linker. The formation of the GG-Cys-Quer conjugate was supported by FTIR, 1H/13C NMR, CHNS elemental analysis, degree-of-substitution estimation, SEM, and TGA. The conjugate showed potent antifungal activity against five clinical C. auris isolates, with MIC and MFC values ranging from 0.030 to 0.245 \u00b5g mL-1 and 0.123 to 0.488 \u00b5g mL-1, respectively. Against the resistant isolate MRL6057, GG-Cys-Quer showed an MIC of 0.245 \u00b5g mL-1, whereas caspofungin showed an MIC of 4.0 \u00b5g mL-1 under the same assay conditions. Mechanistic studies showed increased intracellular ROS accumulation, loss of mitochondrial membrane potential, and apoptosis-associated changes, as confirmed by Annexin V/PI staining, with a concentration-dependent increase in late apoptotic/necrotic cell populations at higher exposure levels. Ultrastructural analysis further revealed membrane deformation, pore formation, and cellular collapse, supporting severe fungal cell damage following treatment. In mammalian L929 fibroblasts, GG-Cys-Quer maintained >85% cell viability at MFC-level exposure, indicating preliminary in vitro cytocompatibility. Overall, these findings demonstrate that GG-Cys-Quer is a structurally characterized guar gum-quercetin conjugate with strong in vitro antifungal activity against C. auris and a mechanism involving oxidative stress, mitochondrial dysfunction, and apoptosis-associated fungal cell death. Further side-by-side studies with free quercetin, linker controls, guar gum controls, and in vivo models are required to define the specific contribution of conjugation and assess translational potential.\n\nID: 42515081\nTitle: Phosphoproteomics of WHO-Priority Fungal Pathogens: Conserved Signaling Architecture, Pathogen-Specific Outputs, and Therapeutic Vulnerabilities.\nAbstract: Protein phosphorylation is a central post-translational modification. In pathogenic fungi, it dynamically governs morphogenesis, stress adaptation, and antifungal drug resistance. Using high-resolution mass spectrometry-based phosphoproteomics, researchers have systematically mapped phosphorylation dynamics in WHO-priority pathogens-Candida albicans, Aspergillus fumigatus, Cryptococcus neoformans, and the multidrug-resistant Candidozyma auris (formerly Candida auris). These studies reveal that thousands of phosphorylation events are coordinately reprogrammed in response to antifungal drug exposure, host-derived oxidative stress, and temperature shifts. Integration of available datasets suggests a \"conserved-core/divergent-output\" organization. Shared kinase hubs like cAMP-PKA, HOG-MAPK and calcineurin are broadly conserved across species. Downstream substrate networks, however, have diverged, producing distinct virulence outputs in each pathogen. Notably, C. auris remains completely uncharacterized at the phosphoproteomic level. This review provides a comprehensive synthesis of the phosphoproteomic landscape across these pathogens, and discusses how phosphoproteomic data are guiding the rational prioritization of kinases and phosphatases as next-generation antifungal drug targets-with direct implications for clinical surveillance and public health.\n\nID: 42513906\nTitle: Comparative Analysis of Virulence Traits and Fluconazole-Response Mechanisms in Clinical Isolates of Candidozyma auris.\nAbstract: Candidozyma auris (formerly known as Candida auris) has emerged as a formidable clinical fungal pathogen as a result of its multidrug resistance and persistent colonization capabilities. In this study, three clinical C. auris strains (namely C. auris strain 01, C. auris strain 03, and C. auris strain 13) with distinct origins were characterized to investigate their phenotypic variations and mechanisms of azole resistance. Comprehensive profiling revealed significant inter-strain differences in biofilm formation, cell surface hydrophobicity, adhesion capacity, and phospholipase activity. Testing for antifungal susceptibility showed that the three clinical strains exhibited different minimum inhibitory concentrations for multiple azoles (fluconazole, voriconazole, and itraconazole) and echinocandins (anidulafungin and micafungin). Sequencing identified Y132F mutations in the ERG11 gene of the three clinical strains. Mechanistic investigations demonstrated that fluconazole exposure significantly upregulated the expression of efflux pump genes (CDR1 and CDR2) and the genes encoding their transcriptional regulators (MDR1 and TAC1b). In a murine skin colonization model, comparing data from the standard strain C. auris strain CBS12766 and clinical strains of C. auris strain 03 and C. auris strain 13 exhibited a significantly higher fungal burden of tissue, whereas strain C. auris strain 01 showed an intermediate level. Host immunity response analysis revealed that expression of the IL-1\u03b2 gene was significantly elevated in C. auris strain CBS12766-infected mice, while expression of IL-6 and CXCL-1 genes was predominantly increased in the C. auris strain 01, with TNF-\u03b1 gene expression levels being comparable across all strains. Histopathological examination confirmed local infiltration of inflammatory cells and mild epidermal edema, indicating active host immune engagement. Overall, our findings highlighted substantial phenotypic heterogeneity, different colonization capacities, and differences in expression of inflammatory cytokines among the C. auris strains. Further investigations into fluconazole-response mechanisms identified enhanced efflux pump activity, along with ERG11 gene Y132F mutations and transcription factor modulation among these clinical strains.\n\nID: 42506257\nTitle: Clinical Outcomes of Candida auris Versus Other Candida Species Bloodstream Infections: An IPTW-Adjusted Cohort Study in South Korea.\nAbstract: Candida auris has emerged as a multidrug-resistant, healthcare-associated pathogen worldwide; however, outcome data on C. auris candidaemia in East Asia remain limited. We conducted a retrospective cohort study of adult patients with candidaemia who received antifungal therapy at a tertiary hospital in Seoul, Republic of Korea, from January 2023 to December 2024, comparing C. auris with other Candida species. Confounding was addressed by inverse probability of treatment weighting (IPTW) using a five-covariate propensity score (age, Charlson Comorbidity Index, septic shock, ICU admission at antifungal initiation, and concomitant Gram-negative infection). Among 423 patients, C. auris accounted for 6.9% of cases and was uniformly fluconazole non-susceptible, with frequent high-level caspofungin resistance but preserved micafungin and anidulafungin susceptibility. Patients with C. auris were older, with greater comorbidity and more frequent ICU admission at antifungal initiation. After IPTW adjustment, C. auris was not associated with higher 30-day mortality, the primary outcome (adjusted hazard ratio 0.59, 95% CI 0.26-1.32); the wide confidence interval indicates limited precision rather than equivalence, and results were directionally consistent for 90-day and in-hospital mortality and across sensitivity analyses that varied both the comparison cohort and the analytic method. Residual confounding by unmeasured illness severity and limited precision preclude concluding equivalence. Continued surveillance, molecular characterisation, and infection control remain essential.\n\nID: 42505655\nTitle: Field Evaluation of the ClaID PCR System Reveals Predominance of Clade I-Associated Molecular Profiles Among Clinical Candida auris Isolates Recovered in \u0130stanbul, T\u00fcrkiye.\nAbstract: Background:Candida auris has emerged globally as a multidrug-resistant fungal pathogen responsible for healthcare-associated outbreaks and invasive infections. Whole-genome sequencing studies have demonstrated the existence of genetically distinct clades that differ in geographical distribution, antifungal resistance patterns, virulence traits, and outbreak potential. Objectives: This study aimed to evaluate the performance of the ClaID clade identification PCR system among clinical Candida auris isolates collected in \u0130stanbul, T\u00fcrkiye, and to investigate the clade-associated molecular profiles of circulating isolates. Methods: Forty-four clinical C. auris isolates were analysed using the auris universal sequence (AUS) assay and clade-specific sequence assays (CSS1-CSS5). PCR amplification results were interpreted according to the ClaID framework. Results: AUS amplification was detected in 41/44 isolates (93.2%). CSS1 amplification was observed in 39/44 isolates (88.6%), indicating a predominance of Clade I-associated molecular profiles within this regional \u0130stanbul isolate collection. No amplification was detected using CSS2, CSS3, CSS4, or CSS5 assays. Three isolates were AUS-negative and five isolates did not yield CSS1 amplification despite repeated testing. Conclusions: The findings suggest that the majority of analyzed clinical isolates from \u0130stanbul exhibited Clade I-associated molecular profiles rather than definitive WGS-confirmed clade assignments. This study provides one of the first field evaluations of the ClaID system in a Turkish clinical isolate collection and contributes regional molecular epidemiological data regarding PCR-based clade-associated profiles of C. auris in T\u00fcrkiye.\n\nID: 42499548\nTitle: Candida auris: a review of global epidemiology, multidrug resistance, and infection control in healthcare-associated outbreaks.\nAbstract: Candida auris, designated a critical-priority fungal pathogen by the World Health Organization, poses a growing threat to healthcare systems worldwide. Analysis of 80 peer-reviewed studies reveals five principal findings: (1) C. auris exhibits clade-dependent geographic distribution and resistance profiles-Clade I (South Asia) and Clade III show fluconazole resistance exceeding 90%, whereas Clade IV exhibits 44% resistance; echinocandin resistance varies significantly by clade and no resistance was detected in certain clades; amphotericin B resistance varies from no detected resistance to 46% depending on clade; and pan-resistant strains have emerged; (2) biofilm-associated C. auris cells (sessile cells) exhibit MBECs 2- to 4,119-fold higher than planktonic MICs, representing a major driver of persistent colonization; (3) novel antifungal agents, including ibrexafungerp, manogepix (the active moiety of fosmanogepix), and rezafungin, demonstrate promising in vitro activity against C. auris, with manogepix showing the highest overall antibiofilm activity (geometric mean MBEC of 5.9 \u03bcg/mL) and ibrexafungerp demonstrating superior activity against Clade IV biofilms; (4) a tiered infection prevention and control (IPC) framework-integrating universal screening, contact precautions, and environmental decontamination-has been associated with reduced transmission rates in outbreak settings; and (5) climate change and global warming may have contributed to the emergence of C. auris through thermal adaptation of environmental fungal species. These findings indicate that effective mitigation of the C. auris threat requires integrated surveillance, susceptibility-guided therapy accounting for both planktonic and biofilm activity, and resilient healthcare systems adapted to the clade-specific epidemiology of this pathogen.\n\nID: 42497227\nTitle: Clinical and microbiological epidemiology of Candida infections in a high-complexity hospital in Tolima, Colombia (2014-2024).\nAbstract: Candida spp. infections are an increasing challenge in high-complexity hospitals, yet epidemiological data remain scarce in underrepresented in Colombian regions such as Tolima. We conducted a retrospective observational study in a high-complexity hospital in Ibagu\u00e9 (Tolima, Colombia) from 2014 to 2024, integrating two institutional data sources: administrative/clinical records and the microbiology laboratory database (WHONET). Species identification relied on culture and VITEK, and antifungal susceptibility was interpreted using criteria from the Clinical and Laboratory Standards Institute (CLSI) and the European Committee on Antimicrobial Susceptibility Testing (EUCAST). We summarized data using frequencies/proportions and medians (IQR), explored patterns with multiple correspondence analysis (MCA), and estimated associations with candidemia using penalized multivariable logistic regression due to low event frequency. We identified 987 candidiasis episodes and 776 fungal isolates, of which 314 were Candida (40.46%). Mucocutaneous disease predominated (vulvovaginal 50.7%; oropharyngeal 24.3%), while candidemia represented 2.0% of episodes. Among isolates, Candida albicans was most frequent (58.9%), followed by C. parapsilosis (16.6%), C. tropicalis (12.1%), and Nakaseomyces glabratus (6.4%); Candida auris was detected once. In exploratory clinical/administrative models, clinically recorded candidemia showed associations with invasive devices (OR 5.54, 95% CI 2.01-15.64), recent surgery (OR 7.11, 95% CI 1.20-30.88) and tumor (OR 19.88, 95% CI 3.14-97.51). Susceptibility data were available for 196/314 isolates (62.4%); echinocandin activity was high, whereas azole susceptibility was more variable. Candidiasis showed a sustained recorded burden and substantial non-albicans diversity, supporting local surveillance, species-level identification, and isolate-level susceptibility testing.\n\nID: 42494096\nTitle: Development and Validation of AurisC2-ID, a Fourier-Transform Infrared Spectroscopy Classifier for Differentiation of Clade II and Non-Clade II Candida auris Isolates.\nAbstract: Candida auris clade II isolates are generally more susceptible to antifungal agents and are less frequently associated with outbreaks than non-clade II isolates. We developed and validated a Fourier-transform infrared (FTIR) spectroscopy-based classifier (AurisC2-ID) to distinguish clade II from non-clade II C. auris isolates. In total, 106 C. auris isolates col-lected from 14 Korean hospitals, representing clades I and II, and 10 reference isolates from the Centers for Disease Control and Prevention and Food and Drug Administration Antimicrobial Resistance Isolate Bank, representing four clades (I-IV), were analyzed using FTIR spectroscopy (IR Biotyper; Bruker Daltonics, Bremen, Germany) as the training set for classifier development. The classifier was constructed using an artificial neural network al-gorithm following principal component analysis and was validated using 87 additional clini-cal isolates collected from nine Korean hospitals. The training set spectra showed clear separation between clade II and non-clade II isolates, with minor overlap between the two groups. During validation, all 31 clade II isolates were correctly classified as clade II, and the remaining 56 clade I isolates as non-clade II. These results demonstrate that AurisC2-ID can accurately distinguish clade II from non-clade II C. auris isolates and may serve as a useful tool for infection control in Korea.\n\nID: 42474134\nTitle: Pharmacological advances in Candida auris: emerging antifungal mechanisms and next-generation therapeutic strategies.\nAbstract: Candida auris is a major public health concern worldwide due to its efficient transmission, environmental persistence, and broad resistance to approved antifungal classes. This review consolidates recent pharmacological developments in this regard, focusing on mechanistic insights and late-stage therapeutics. Novel agents demonstrate activity against multidrug- and pan-resistant isolates via distinct mechanisms of action and enhanced specific binding to CYP51. Repositioned drugs, host-defense peptides, and quorum-sensing modulators also expand the treatable spectrum, particularly for biofilm-associated and device-related infections. Concurrently, artificial intelligence (AI)-guided discovery, nanocarrier-enabled delivery, and multi-omics profiling are greatly accelerating target identification and enhancing the drug metabolism of small-molecule fragments. The emerging combined approaches mark a transition towards mechanism-based antifungal development to combat the increasing clinical burden posed by C. auris. Ongoing integration of precision diagnostics, pharmacodynamic optimization, and novel discovery platforms will be key to translating these advances into durable, real-world therapeutic solutions.\n\nID: 42470541\nTitle: Environmental Detection of Candidozyma (Candida) auris in Surface Waters of the Gediz Delta, a Critical Coastal Wetland in T\u00fcrkiye: Expanding One Health Surveillance Perspective.\nAbstract: Candidozyma auris (syn. Candida auris) is an emerging multidrug-resistant yeast of growing clinical and environmental concern. Despite its increasing detection in healthcare settings worldwide, environmental evidence remains scarce. This study presents the first molecular detection of C. auris DNA in surface waters of T\u00fcrkiye, within the Ramsar-protected Gediz Delta, as part of the national One Health Surveillance Framework. A total of 80 surface-water samples were collected from five wetland ecosystems Tuz Lake, Kulu Lake, G\u00f6ksu Delta (Akg\u00f6l and Paradeniz Lagoons), K\u0131z\u0131l\u0131rmak Delta, and Gediz Delta. Physicochemical parameters; temperature, pH, and salinity were recorded in situ using a multi parameter sensor. Environmental DNA was extracted from 2\u00a0L of 0.22\u00a0\u00b5m Sterivex-filtered water and analyzed via qPCR using C. auris-specific (CauF/CauR) and Candida-genus (CauRelF/CauRelR) primer sets. Yeast isolation was performed on CHROMagar\u2122 Candida Plus, and identification was achieved by MALDI-TOF MS. C. auris DNA was detected in one sample (1.25%), specifically from the Gediz Delta (Sample No. 5651, 38.523\u00b0\u00a0N, 26.892\u00b0\u00a0E), with Ct values 33.8-37.2 confirmed by sequencing. Broader Candida genus signals were observed in 24% of samples. Culture-based analyses yielded no viable C. auris, but 15 yeast isolates were identified, mainly Pichia kudriavzevii (Candida krusei), C. albicans, and Nakaseomyces glabratus (Candida glabrata). The culture-negative yet qPCR-positive finding indicates that C. auris DNA likely persists in aquatic environments as non-viable or residual material. This finding provides early molecular evidence of environmental dissemination and underscores the need for viability assays, culture-based isolation, and metagenomic monitoring integrated within One Health surveillance programmes.\n\nID: 42445483\nTitle: Integrative computational-experimental discovery and translation of antifungal peptides for multidrug-resistant fungi.\nAbstract: Multidrug-resistant fungal infections caused by Candida and Aspergillus species have become one of the major global health concerns, especially among immunocompromised individuals. The small number of antifungals available and the rapid emergence of resistance to azoles, echinocandins and polyenes underscore the urgent need to develop alternative therapeutic strategies with different mechanisms of action. Antifungal peptides (AFPs) have attracted increasing attention as promising candidates due to their broad-spectrum activity, multimodal mechanisms of action, and their low likelihood of resistance development. This review presents a thorough and holistic summary of the research on AFPs that target clinically significant drug-resistant fungi such as Candida auris, azole-resistant Candida albicans, and triazole-resistant Aspergillus fumigatus. We review the structural and physicochemical properties of AFPs and address their various antifungal mechanisms, which include membrane disruption, oxidative stress induction, and disruption of intracellular homeostasis, as well as biofilm inhibition. We further highlight an emerging computational-experimental pipeline to discover and optimize AFPs, combining sequence mining, machine learning-based screening, molecular docking, molecular dynamics simulations, and in vitro and in vivo validation. We also explore the major translational challenges, such as hemolytic toxicity, proteolytic instability, pharmacokinetic constraints, manufacturing complexity, regulatory concerns, and sustainable peptide manufacturing strategies, and discuss advanced delivery systems (e.g., liposomes, PLGA nanoparticles, chitosan-based systems, and hydrogels) to improve therapeutic efficacy and stability. In summary, this review proposes an integrated translational development framework that connects computational design, experimental validation, and delivery engineering, thereby positioning AFPs as a promising next-generation strategy in the fight against multidrug-resistant fungal infections.\n\nID: 42436212\nTitle: Designing a chimeric multi-epitope vaccine against Candida auris using reverse vaccinology approach targeting the agglutinin-like protein N-terminal domain.\nAbstract: Candida auris is an emerging multidrug resistant fungal pathogen associated with high mortality rates, rapid global dissemination and resistance to conventional antifungal therapies. It's remarkable ability to evade host immune responses and persist in health care setting demands the development of effective immunotherapeutic strategies. In this study, a reverse vaccinology and immunoinformatics based approach was employed to design a novel chimeric multi-epitope vaccine targeting surface expose N-terminal domain of the agglutinin like protein involved in host pathogen interactions. High affinity B-cell and T-cell (MHC class I and II) epitopes were identified and screened based on antigenicity, allergenicity, toxicity and population coverage. Selected epitopes were assembled using optimized linkers (EAAAK, AAY and GPGPG) along with an adjuvant to enhance immunogenicity and structural stability. Physicochemical characterization, structural validation, molecular docking with human Toll-like receptor 4 (TLR4), Normal Mode Analysis (NMA), immune simulation, codon optimization and in silico cloning into the pET28a+ vector were performed to evaluate the vaccine construct. The selected epitopes demonstrated a global population coverage of 97.31%. the final vaccine construct was predicted to highly antigenic, non-allergenic, structurally stable and soluble. Molecular docking analysis revealed strong and stable interactions between the vaccine construct and human TLR4, with a binding energy of - 906.1\u00a0kcal/mol. Normal Mode Analysis further supported the structural stability of the vaccine receptor complex. Immune simulations predicted robust primary and secondary responses characterized by elevated IgG and IgM antibodies along with a Th1-skewed cytokine profile dominated by IFN-\u03b3 and IL-2 expression. Codon optimization and in-silico cloning indicated favorable translational efficiency in the pET28a+ expression system. The designed chimeric multi epitope vaccine demonstrated promising immunogenic, structural and receptor binding properties against Candida auris. These findings suggest that the proposed vaccine construct may serve as a potential candidate for further experimental validation and future development of effective immunotherapeutic interventions against multidrug- resistant fungal infections.\n\nID: 42431934\nTitle: Segmental duplications and supernumerary chromosomes drive antifungal drug resistance in Candida auris.\nAbstract: Candida auris, a World Health Organisation-listed critical priority fungal pathogen, causes frequent multidrug-resistant outbreaks worldwide. While point mutations underlying antifungal resistance are well characterised, the contribution of structural genomic variation to antifungal responses remains poorly defined. Here, we integrate whole-genome sequencing, a genome-wide copy number variation (CNV) screen, electrophoretic karyotyping, and mutation-accumulation analyses to investigate the role of structural variation in antifungal susceptibility across a clinical cohort of C. auris isolates. We identify recurrent CNV hotspots, with segmental duplications representing a predominant mode of genome variation. Small duplications encompassing ERG11 arise at high frequency and frequently co-occur with drug resistance-associated ERG11 mutations, collectively enhancing azole resistance. In addition, large centromere-inclusive duplications of chromosome 1 generate supernumerary chromosomes, leading to paradoxical growth and reduced susceptibility to caspofungin, an echinocandin. At the population level, structural variants frequently arise in parallel to FKS1 mutations, suggesting multiple genetic mechanisms underlying reduced drug susceptibility. Together, our findings establish segmental duplication as a major, non-mutational driver of antifungal resistance, highlighting the need to consider structural genomic variation in both resistance surveillance and clinical susceptibility testing.\n\nID: 42423514\nTitle: Diagnostic Performance of Direct PCR Assay for Candida auris Detection: A Comparison of Liquid Amies Transport Medium and Fungal Enrichment Broth.\nAbstract: Candida auris has rapidly spread worldwide, representing a significant global health threat. Rapid diagnostic testing is essential for C. auris infection control. This study aimed to assess the diagnostic performance of a direct polymerase chain reaction (PCR) assay compared with culture. The liquid Amies transport medium (Copan ESwab; Copan, Italy) and fungal enrichment broth were compared to determine the optimal media for the direct PCR assay. The diagnostic performance of the cobas omni Utility Channel Reagent Kit (Roche Diagnostics, Germany)-based direct PCR assay and culture was assessed against clinical outcomes. Sixty skin swab specimens were prospectively collected from intensive care unit patients at a university hospital in Korea. Each sample was tested in parallel using the Copan ESwab and Sabouraud dextrose (SD) broth. The direct PCR assay showed a sensitivity of 92.0%-96.0% and specificity of 85.7%-97.1% compared with a sensitivity of 76.0%-80.0% and specificity of 100% for culture across both media. For the direct PCR assay, the Copan ESwab showed a higher specificity, positive predictive value, and kappa value but lower sensitivity and negative predictive value than the SD broth. The discordant direct PCR assay-positive/reference standard-negative and PCR assay-positive/culture-negative cases showed significantly higher cycle threshold values than the concordant cases (p\u2009<\u20090.05). The direct PCR assay using the Copan ESwab showed high sensitivity for the detection of C. auris in clinical skin swab specimens. This approach may be useful for screening, although further validation in larger multicenter studies is needed.\n\nID: 42406015\nTitle: The Emerging Global Threat of Candida auris: A Call for Enhanced Public Health Policy and Regional Coordination.\nAbstract: Antimicrobial resistance represents a paramount challenge to global public health in the 21st century. The multidrug-resistant fungal pathogen Candida auris poses a critical and escalating threat to global public health. Characterized by rapid nosocomial transmission, persistent environmental contamination, and resistance to multiple antifungal classes, C. auris challenges healthcare systems worldwide. Its independent emergence across distinct geographic clades and exponential rise in cases, exacerbated by the COVID-19 pandemic, underscore the urgent need for robust, coordinated response. This review synthesizes the current knowledge on C. auris with a focus on its implications for public health policy, particularly in the European and Balkan healthcare settings, where surveillance gaps and cross-border transmission risks remain pronounced. We analyze the key drivers of spread, including diagnostic misidentification, extensive antifungal resistance, and lapses in infection control, and evaluate the strain on surveillance and hospital preparedness. Effective mitigation is fundamentally dependent on implementing comprehensive, multi-faceted infection prevention and control strategies, guided by antifungal stewardship and rapid diagnostics. We conclude that addressing the C. auris threat requires an urgent, coordinated international and regional response focused on strengthening surveillance networks, standardizing diagnostic and infection prevention and control protocols, and fostering data sharing across borders to contain this resilient pathogen.\n\nID: 42405804\nTitle: Morphotype-specific susceptibility to Neosartorya (Aspergillus) fischeri antifungal protein 2 is associated with an anabolic transcriptional signature in Candida.\nAbstract: The emergence of drug-resistant Candida species has created a demand for global antifungal strategies that extend beyond classical growth inhibition to target unknown vulnerabilities of fungal pathogens. In this study, we demonstrated that the Neosartorya (Aspergillus) fischeri antifungal protein NFAP2 selectively targets early morphogenetic states of Candida albicans and Candidozyma auris, revealing a transient window of susceptibility during filament and pseudohypha formation. Integrated transcriptomic and in vivo analyses indicate that these developmental states may represent context-dependent entry points for NFAP2 activity. In C. albicans, transcriptomic and network analyses indicate the presence of an anabolic, translation-associated gene expression signature, accompanied by suppression of stress-protective pathways, which is associated with increased susceptibility of emerging hyphae to NFAP2 but does not establish a direct causal mechanism. In C. auris, increased susceptibility of pseudohyphal cells occurred without overt transcriptional remodeling, consistent with the characteristically muted gene expression responses of this species, suggesting that NFAP2 sensitivity is governed primarily by biophysical and post-transcriptional mechanisms rather than transcriptional reprogramming. Importantly, morphotype-specific vulnerabilities observed in vitro were reflected in distinct in vivo outcomes in Galleria mellonella, as NFAP2 was well tolerated and provided a moderate, transient survival benefit in pseudohyphal C. auris infections, but not in filamentous C. albicans, where a worsened outcome was observed, consistent with species- and morphotype-dependent activity. Taken together, these results suggest that early morphogenetic states of Candida are stress-sensitive phenotypes associated with increased susceptibility to NFAP2. This work provides a proof-of-concept framework for future investigation of morphotype-associated antifungal vulnerability to peptide-based antifungal strategies.IMPORTANCEDrug-resistant Candida species represent an escalating global health threat; however, most antifungal strategies continue to target fungal growth rather than intrinsic biological vulnerabilities. In this study, we identified early morphogenetic transitions as a shared window of increased susceptibility in both Candida albicans and the highly drug-resistant pathogen Candidozyma (formerly Candida) auris. By integrating transcriptomic profiling with in vivo infection models, we found that NFAP2 exhibits antifungal activity that is influenced by these transient developmental states in a context-dependent manner while remaining well tolerated by the host. We further demonstrated that morphotype-specific stress responses are associated with the divergent sensitivities of C. albicans and C. auris to NFAP2. These results support the concept that fungal morphogenesis may represent a therapeutically actionable process and provide a framework for designing antifungal strategies that target developmental states rather than growth. This strategy may open new opportunities for improving protein- and peptide-based therapies, as well as combination therapies against difficult-to-treat fungal pathogens.\n\nID: 42405803\nTitle: Candida spp. suppress neutrophil reactive nitrogen species to evade killing.\nAbstract: Candida albicans is a human commensal that can cause life-threatening invasive infection in immunocompromised individuals. Human immunity to C. albicans infection is thought to be largely dependent on neutrophil reactive oxygen and nitrogen species (ROS/RNS) generation by neutrophils. Despite this, our understanding of innate immune killing and escape by C. albicans is primarily studied in macrophages, and the precise mechanisms of evasion are unclear in neutrophils. Here, we sought to determine the importance of neutrophil reactive nitrogen species (RNS) production during C. albicans infection in vivo. Using a zebrafish model, we found that C. albicans rapidly downregulated neutrophil RNS below basal levels during the first day post-infection, a time at which neutrophil RNS is upregulated in bacterial infections as an important host-defense mechanism, indicating fungal evasion of host neutrophils. We confirmed the downregulation of RNS in human primary neutrophils and with clinical Candida isolates, including emerging human pathogens Candida auris and Candida glabrata. Inducible nitric oxide synthase (iNOS; Nos2 in zebrafish), the enzyme responsible for RNS production, competes with the arginase enzyme for a shared substrate, L-arginine. Using a zebrafish arginase2 transgenic line and a C. albicans car1\u0394 mutant, we showed that both host and fungal arginase contribute to the reduction in neutrophil RNS. Despite pathogen downregulation, upregulation of neutrophil RNS via hypoxia-inducible factor 1\u03b1 (Hif-1\u03b1) stabilization was sufficient to improve host survival following C. albicans infection. Inhibition of Nos2 blocked the host protective effect of Hif-1\u03b1 stabilization. Finally, restoration of neutrophil RNS via Hif-1\u03b1 stabilization was additive to clinically relevant antifungal treatment, increasing survival and clearance of C. albicans infections. Together, these data demonstrate that restoration of the neutrophil RNS response in C. albicans infection improves infection outcomes, highlighting the potential of targeting Hif-1\u03b1 and RNS in host-directed therapies against fungal infections.IMPORTANCECandida albicans is a fungus that normally lives harmlessly in the human body but can cause life-threatening infections in people with weakened immune systems. A key part of the body's defense against this fungus is neutrophils, immune cells that kill microbes using toxic molecules. However, how Candida avoids neutrophil defense is not well understood. Here, we used zebrafish and human immune cells to show that Candida suppresses an important neutrophil defense, reactive nitrogen species (RNS), during infection. Unlike bacteria, which trigger RNS, Candida reduces these protective molecules to below normal levels, helping its survival. This effect was also observed with other disease-causing Candida species. We went on to show that both the host and Candida contribute to this suppression. Importantly, boosting the neutrophil response improved survival and helped clear infection, especially when combined with standard antifungal drugs. These findings suggest new ways to support the immune system alongside existing treatments.\n\nID: 42396049\nTitle: C. auris in Wastewater: Current Evidence, Risks, One Health Implications, and Knowledge Gaps.\nAbstract: Candidozyma aurisauris (formerly Candida auris) is an emerging, multidrug-resistant fungal pathogen that is difficult to identify and has become an increasing challenge for global public health. In recent years, its detection in wastewater has raised concerns regarding the potential environmental dimensions of its dissemination and the associated public health implications. This study examines the current evidence on the occurrence of C. auris in wastewater, with an emphasis on the concentration, isolation, and identification methodologies employed in recent investigations. Framed within a One Health perspective, the analysis discusses potential pathways of environmental dissemination through wastewater effluents and biosolids, particularly in the context of the expanding reuse of treated wastewater and the land application of sewage sludge. The review also highlights existing regulatory gaps, including the absence of specific guidelines addressing pathogenic fungi in wastewater treatment plant byproducts as well as the lack of standardization in reported data, which hinders more in-depth analyses. Overall, this work identifies important knowledge gaps and emphasizes the need for further studies and interdisciplinary surveillance strategies to better understand the environmental circulation of C. auris. Additionally, a conceptual workflow is proposed to advance the standardization of analytical approaches and data reporting, contributing to strengthening public health, environmental protection, and sanitary policies.\n\nID: 42378120\nTitle: Surveillance for Candida auris - United States, 2022-2024.\nAbstract: Candida auris is an emerging yeast that is frequently resistant to antifungal drugs. C. auris can cause invasive infections associated with high mortality and can colonize patients asymptomatically, which facilitates transmission in health care settings. Since it was first reported in the United States in 2016, C. auris has been identified in multiple states, with increasing numbers of cases reported annually. Monitoring national trends in cases identified through clinical testing and screening for colonization is critical to guide infection prevention and control efforts. 2022-2024. State and jurisdictional health departments voluntarily report clinical and screening C. auris cases to CDC using standardized case definitions of the Council of State and Territorial Epidemiologists. Clinical cases are defined as detection of C. auris from specimens collected for diagnostic purposes; screening cases are defined as detection from colonization screening swabs. Cases were reported to CDC through the Research Electronic Data Capture (REDCap) or Data Collation and Integration for Public Health Event Response (DCIPHER) platforms. Data included patient age and sex, case type, specimen type (for clinical cases), health care facility type, Antimicrobial Resistance Laboratory Network geographic region, and specimen collection date. Analyses were descriptive and limited to cases with specimens collected during 2022-2024. During 2022-2024, a total of 13,507 clinical C. auris cases were reported to CDC, increasing from 2,882 in 2022 to 4,428 in 2023 and 6,197 in 2024, with smaller annual percentage increases over time (53.7% from 2022 to 2023 and 39.9% from 2023 to 2024). Most clinical cases occurred among adults aged \u226545 years (87.8%) and among males (61.0%). The most common specimen types among all clinical cases were urine (31.5%) and blood (30.2%); by year, the proportion of blood as the specimen type was 34.4% in 2022, 30.2% in 2023, and 25.6% in 2024. Most clinical cases were identified through specimens collected in acute care hospitals (76.6%) and long-term acute care hospitals (17.8%).During the same period, a total of 27,853 screening cases were reported to CDC, increasing from 6,226 in 2022 to 9,195 in 2023 and 12,432 in 2024. Screening cases most frequently occurred among adults aged \u226545 years (90.0%) and males (57.9%). Among cases with known facility type, the proportion of specimens collected in acute care hospitals increased from 24.7% in 2022 to 50.7% in 2024, whereas the proportion of specimens collected in long-term acute care hospitals decreased from 56.1% to 35.7% during the same period. The number of clinical and screening C. auris cases reported to CDC increased during 2022-2024, indicating ongoing transmission in U.S. health care settings. Although annual percentage increases in clinical cases declined over time, absolute case counts reported to CDC continued to rise. The increasing proportion of screening cases with specimens collected in acute care hospitals might reflect increased use of screening in acute care hospitals, including screening at admission. Because of increases in the number of reported C. auris cases, sustained infection prevention and control efforts in health care facilities, including adherence to transmission-based precautions, environmental disinfection with agents effective against C. auris, and communication of C. auris status during patient transfers remain essential to preventing clinical infections and colonization. Because this pathogen is frequently resistant to antifungal drugs, continued investment in laboratory capacity and surveillance, including antifungal susceptibility testing and screening of patients at high risk for C. auris infection, can support timely detection and guide prevention strategies. Ongoing public health coordination at federal, state, and local levels is critical to limit further spread and to address emerging antifungal drug resistance.\n\nID: 42375658\nTitle: Infection prevention and control of Candida auris in pediatric settings.\nAbstract: Candida auris (also referred to as Candidozyma auris) is an emerging multidrug-resistant fungal pathogen associated with high morbidity and mortality. Existing infection prevention and control (IPC) guidance has largely focused on adult populations, with limited recommendations for pediatric healthcare and non-healthcare settings. The Society for Healthcare Epidemiology of America (SHEA) convened a multidisciplinary expert panel to develop IPC recommendations for C. auris. The panel developed recommendations using a structured, iterative Delphi consensus process with rounds of discussion, refinement, and anonymous electronic voting with predefined consensus thresholds. Panelists reviewed relevant peer-reviewed and gray literature integrated with expert judgment and practical considerations. Preambles and remarks provide additional context and guidance. This consensus statement provides recommendations for prevention of C. auris in pediatric acute care settings, non-acute healthcare settings, and non-healthcare congregate settings. Recommendations incorporate pediatric risk factors and care and address screening practices, isolation precautions, caregiver-infant/child dyad considerations, room placement and rooming in, breastfeeding and skin-to-skin practices, visitation, use of shared spaces, environmental cleaning and disinfection, and management of medical and non-medical equipment, including toys. Recommendations emphasize coordination with local infection prevention and public health partners. This SHEA consensus statement addresses gaps in pediatric-specific IPC guidance for C. auris. The recommendations provide a practical framework to support prevention of transmission within the context of pediatric clinical, developmental, and family-centered care.\n\nID: 42370688\nTitle: Multicenter performance evaluation of the Simplexa C. auris Direct assay for the detection of Candida auris colonization in bilateral axilla/groin swabs.\nAbstract: Candida auris is a multidrug-resistant fungal pathogen associated with healthcare outbreaks and high mortality. Its accurate and timely identification is critical for infection prevention, yet conventional culture-based methods are limited by slow growth, morphological ambiguity, and potential misidentification. This multicenter study evaluated the performance of the Simplexa C. auris Direct assay using 2,020 axilla/groin swab specimens collected from six clinical sites compared to culture followed by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS). Specimens were tested prospectively (n = 1,930) and retrospectively (n = 90), with demographic data spanning inpatient, intensive care unit, emergency department, and long-term acute care hospital settings. Discordant results were resolved by bi-directional sequencing, targeting the internal transcribed spacer and D1/D2 regions of the 28S ribosomal DNA gene. Compared to culture followed by MALDI-TOF MS identification, the Simplexa assay demonstrated an overall sensitivity of 94.8% and specificity of 98.7%, with a Cohen's kappa of 0.80, indicating strong agreement. Discordance rates were low (1.4%), and diagnostic accuracy was high (98.6%). The limit of detection was 127 CFU/mL for Clade I and 260 CFU/mL for Clade IV. Mean cycle threshold values were significantly lower in culture-positive specimens (25.1, 95% CI, 23.6-26.7) compared to culture-negative ones (33.6, 95% CI, 32.1-35.0; P < 0.0001). Comparative analysis with four lab-developed molecular tests (LDTs) showed low rates of discordance: 0.9% for LDT 1 and 2, 1.5% for LDT 3, and 0% for LDT 4, indicating a high level of agreement between the molecular methods. The Simplexa C. auris Direct assay provides a rapid and reliable alternative to traditional methods, providing results in under 2 h, supporting early detection and containment of C. auris in healthcare settings. Rapid and accurate detection of Candida auris colonization is essential for preventing healthcare-associated outbreaks and reducing mortality. This multicenter evaluation demonstrates that the Simplexa C. auris Direct assay offers a sensitive, specific, and practical alternative to culture-based methods, enabling earlier identification and containment of C. auris. These findings provide strong evidence to support its implementation in routine infection prevention strategies across diverse healthcare settings.\n\nID: 42370646\nTitle: HAC1 contributes to stress adaptation and virulence in the emerging fungal pathogen Candida auris.\nAbstract: Candida auris (Candidozyma auris) is an emerging multidrug-resistant fungal pathogen that poses a significant global health threat. However, the molecular mechanisms underlying its virulence remain incompletely understood. In this study, we performed in vivo transcriptome analysis using an immunosuppressed mouse gastrointestinal infection model to identify genes associated with host adaptation and virulence during infection. By comparing fungal transcriptomes obtained from colonization and dissemination sites with those from\u00a0in vitro cultures, we identified genes that were consistently upregulated during infection. Among these genes, the unfolded protein response regulator HAC1 was selected as a candidate virulence-associated gene for further analysis. Reverse transcription PCR and sequencing analyses revealed that\u00a0HAC1 mRNA in C. auris undergoes an unconventional splicing event of 287 bp that is enhanced under endoplasmic reticulum stress conditions. The excised region spans the annotated open reading frame boundary, suggesting that the translated region of\u00a0HAC1 may require re-evaluation. Notably, a proportion of HAC1 transcripts appeared to be spliced even under non-stress conditions, indicating a detectable basal level of the unfolded protein response. Differences in splicing dynamics were also observed among clade strains. Functional analyses demonstrated that deletion of\u00a0HAC1 increased sensitivity to endoplasmic reticulum stress. The HAC1 deletion mutant also exhibited reduced virulence in both Galleria mellonella and immunosuppressed mouse infection models, as evidenced by delayed host mortality and decreased fungal burdens, respectively. These findings indicate that HAC1 contributes to endoplasmic reticulum stress adaptation and survival in the host environment and identify\u00a0HAC1 as a virulence-associated gene in C. auris. Candida auris is an emerging multidrug-resistant fungal pathogen. Using in vivo transcriptome analysis, we identified HAC1 as a regulator of endoplasmic reticulum stress adaptation and virulence in infection models. This study provides new insight into stress-response pathways in C. auris virulence.\n\nID: 42369549\nTitle: A targeted drug-repurposing strategy identifies Tavaborole (Kerydin) as a potent fungistatic agent against Candida auris.\nAbstract: Candida auris is an emerging multidrug-resistant fungal pathogen posing a major global health threat. In this study, we employed a targeted drug-repurposing strategy to identify novel indications for existing FDA-approved compounds against C. auris, leading to the identification of Tavaborole as a potent fungistatic agent. Tavaborole displayed robust activity across all five tested clades of C. auris, as well as against Candida albicans and Candida glabrata. To investigate drug resistance mechanisms of C. auris, we applied quantitative proteomics analyses following exposure to Tavaborole and Amphotericin B (AmB), complemented by electron microscopy. Proteomic profiling revealed that C. auris mounts distinct but overlapping adaptive responses to antifungal stress, involving stress response pathways, metabolic reprogramming and amino acid biosynthesis. While Tavaborole primarily induced targeted stress adaptation, AmB triggered a broader, multi-pronged resistance response including oxidative stress mitigation, osmolyte production and metabolic remodeling. Shared alterations in glycogen metabolism and amino acid biosynthesis suggest conserved antifungal adaptation mechanisms. Altogether, this study highlights Tavaborole as a promising antifungal candidate against C. auris, sheds novel insights into drug resistance mechanisms employed by the pathogen and delivers a drug-repurposing procedure highly customizable to target other microorganisms.\n\nID: 42368398\nTitle: Healthcare-associated infections and antimicrobial resistance in Canadian acute care hospitals, 2020-2024.\nAbstract: Healthcare-associated infections (HAIs) and antimicrobial resistance (AMR) continue to contribute to excess morbidity and mortality among Canadians. To describe epidemiologic and laboratory characteristics and trends of HAIs and AMR, 2020-2024, using surveillance and laboratory data submitted by hospitals to the Canadian Nosocomial Infection Surveillance Program (CNISP) and by provincial and territorial laboratories to the National Microbiology Laboratory. Data was collected from 109 Canadian sentinel acute care hospitals between January 1, 2020 and December 31, 2024 for Clostridioides difficile infections (CDI), methicillin-resistant Staphylococcus aureus (MRSA) bloodstream infections (BSIs), vancomycin-resistant Enterococcus (VRE) BSIs (specifically Enterococcus faecalis and Enterococcus faecium), carbapenemase-producing Enterobacterales (CPE) and carbapenemase-producing Acinetobacter baumannii (CPA) infections and colonizations and Candidozyma auris (C. auris; formerly Candida auris) infections. Trend analysis for case counts, incidence rates (rates), outcomes, molecular characterization and AMR profiles are presented. From 2020 to 2024, rates remained relatively stable for CDI (range: 5.01-5.38 infections per 10,000 patient days) and MRSA BSI (range: 0.99-1.16 infections per 10,000 patient days) and increased significantly for VRE BSIs (from 0.30 to 0.42 infections per 10,000 patient days; p=0.01). During this time, infection rates for CPE remained low compared to other HAIs but increased significantly (rates: 0.05-0.20; p=0.03), CPA counts continue to remain very low (n=22 infections) and C. auris counts remained low compared to other HAIs (n=43 isolates). The incidence of MRSA BSIs and CDI remained stable and VRE BSIs and CPE infections increased in the Canadian acute care hospitals participating in CNISP. An increased number of C. auris isolates were identified. Reporting standardized surveillance data to inform the application of infection prevention and control practices in acute care hospitals is critical to help decrease the burden of HAIs and AMR in Canada.\n\nID: 42366948\nTitle: Colonization with multidrug-resistant organisms (MDROs) including Candidozyma auris among residents in ventilator-designated versus non-ventilator-designated beds at skilled nursing facilities (SNFs).\nAbstract: Across 13 surveys of 590 residents in seven ventilator-capable SNFs, residents in ventilator-designated beds had markedly higher ESBL (48.1% vs 28.2%; aOR = 1.64) and C. auris (38.6% vs 15.2%, aOR = 2.89), but lower MRSA colonization (35.2% vs 45.5%; aOR = 0.47), supporting the need for MDRO prevention beyond current Enhanced Barrier Precautions.\n\nID: 42358264\nTitle: From fungal diversity to antimicrobial innovation: the potential of biotransformation in the era of resistance.\nAbstract: Antimicrobial resistance (AMR) continues to outpace the development of new anti-infective agents, particularly against priority bacterial pathogens such as Acinetobacter baumannii, Pseudomonas aeruginosa, Klebsiella pneumoniae, and Staphylococcus aureus, as well as clinically relevant fungi including Candida auris. In this scenario, biotransformation has emerged as a complementary innovation strategy for antimicrobial discovery because it expands the chemical space around bioactive scaffolds through selective enzymatic or whole-cell modification. Among the available biocatalysts, fungi are especially attractive due to their metabolic plasticity and broad enzymatic repertoire, including cytochrome P450 monooxygenases, unspecific peroxygenases, laccases, peroxidases, and hydrolases. Current evidence shows that fungal systems can mediate regio- and stereoselective transformations of xenobiotics, aromatics, steroids, terpenes, and lipids, generating structurally refined metabolites of pharmacological and biotechnological interest. This narrative review discusses where fungal biotransformation currently stands as a platform for antimicrobial innovation, highlighting representative enzyme-characterized examples, the main fungal groups and catalytic systems involved, and the experimental workflows used to evaluate these processes. Particular emphasis is given to assay design with growing cells, resting cells, and isolated enzymes, as well as to analytical monitoring by time-course sampling, LC-HRMS/MS, dereplication, molecular networking, isolation, and structural elucidation. Overall, fungal biotransformation is presented as a discovery-enabling platform that links biodiversity, enzymatic catalysis, analytical chemistry, and biological prioritization in the search for new anti-infective molecules.\n\nID: 42349794\nTitle: Response to Wu et al \"Clinical Potential of Antimicrobial Photodynamic Therapy\".\nAbstract: \n\nID: 42348119\nTitle: Unraveling clade-specific differences in Candida auris: evolution, adaptation, and pathogenicity.\nAbstract: Since its 2009 emergence, Candida auris (now also known as Candidozyma auris) has evolved from a rare isolate into a global \"critical priority\" pathogen. This rapid expansion is defined by its unique population structure consisting of six distinct genomic clades with starkly different evolutionary trajectories, phenotypic traits, and clinical risks. We conducted a systematic synthesis of literature from PubMed, Scopus, and Google Scholar (2009-2026), focusing on comparative genomics, clade-specific virulence, and diagnostic accuracy. A total of 64 studies were analyzed to identify patterns in clade divergence and antifungal resistance. Our analysis reveals that C. auris is not a monolithic threat but a complex of diverse lineages with specialized adaptations. Clade I (South Asian) and Clade IV (South American) represent the highest clinical risk due to hyper-virulence and high rates of multi-drug resistant (MDR) strains. In contrast, Clade II (East Asian) was initially associated with localized ear infections; recent genomic data show an expanding pathogenic profile with emerging bloodstream infections. Our review also identifies Clade V (Iranian) as a genetically distinct group and highlights the recent identification of Clade VI (Indomalayan) as a distinct lineage, suggesting a long-standing environmental reservoir. Furthermore, we identify critical \"blind spots\" in automated diagnostic platforms (VITEK\u00ae 2, BD Phoenix) where phenotypic variations in Clades II and III lead to frequent misidentification as Candida haemulonii or Candida famata. This review proposes a \"clade-aware\" framework for public health. While frontline antifungal treatment remains standardized regardless of lineage, we argue that effective long-term management and outbreak containment require integrating genomic surveillance with clade-specific infection control. By identifying high-biofilm clades (Clade I) or hyper-virulent lineages (Clade IV), public health systems can implement more targeted containment strategies, moving toward a precision-based approach to managing this fungal pathogen.\n\nID: 42346566\nTitle: Recent Outbreaks, Resistance Trends, and Control Measures in Candida auris and Candida glabrata Infections.\nAbstract: The global rise in multidrug-resistant (MDR) fungal pathogens has positioned Candida auris and Candida glabrata as major threats to public health. In recent years, these pathogens have increasingly been reported beyond traditional hospital settings, including neonatal intensive care units, long-term care facilities, oncology wards, and post-pandemic critical care environments. International surveillance bodies, including the Centers for Disease Control and Prevention (CDC), European Centre for Disease Prevention and Control (ECDC), World Health Organization (WHO), and regional monitoring networks, have documented escalating antifungal resistance, complex outbreak dynamics, and persistent gaps in infection control implementation. C. auris has emerged as a major etiological agent of healthcare-associated outbreaks, particularly in intensive care and neonatal units. Surveillance data indicate that a high proportion of C. auris isolates exhibit resistance to azoles, often exceeding 80% in some regions, while echinocandin resistance remains variable. Resistance patterns have evolved from predominantly azole resistance to broader multidrug-resistant phenotypes, including treatment-emergent echinocandin resistance. Six genetically distinct clades (I-VI) have been identified, with Clades I, III, and IV associated with large-scale outbreaks, whereas available data suggests that Clades II, V, and VI are more geographically restricted, although evidence for the recently described clades remains limited. C. glabrata is increasingly recognized as a major cause of invasive candidiasis, with rising resistance reported across multiple regions. While reduced azole susceptibility was historically predominant, emerging evidence highlights rising dual azole-echinocandin resistance, adaptive microevolution during antifungal therapy, and biofilm-associated tolerance mechanisms. Despite these advances, significant gaps persist in global resistance surveillance and in the mechanistic understanding of virulence and antifungal adaptation. Current mitigation strategies include antifungal stewardship programs, expanded resistance testing, and strengthened surveillance systems. Advances in rapid diagnostic technologies such as matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry, polymerase chain reaction (PCR)-based assays, and genomic surveillance have improved pathogen identification and outbreak detection, although accessibility remains limited in resource-constrained settings. This review examines emerging epidemiological, genomic, and antifungal resistance trends in C. auris and C. glabrata and highlights key priorities for improving diagnosis, surveillance, stewardship, and management of multidrug-resistant Candida infections.\n\nID: 42554883\nTitle: Antibiofilm and anti-hyphal activity of a valencene-enriched fraction against Candida albicans.\nAbstract: In recent years, the emergence of azole-resistant Candida albicans strains has contributed to increased treatment failure with conventional antifungal therapies. Given the critical role of hyphal formation and biofilm development in C. albicans pathogenicity, this virulence traits represent important but challenging therapeutic targets. In this context, natural products have gained attention as potential sources of novel antivirulence agents. This study investigated the effects of a valencene-enriched fraction (VEF) derived from citrus fruits on the virulence characteristics of C. albicans. VEF significantly inhibited biofilm formation and reduced metabolic activity in vitro. Furthermore, it effectively suppressed the yeast-to-hyphal transition, preventing filamentation under both solid and liquid growth conditions. In an in vivo Caenorhabditis elegans infection model, VEF treatment significantly increased host survival compared to untreated infected controls. Importantly, VEF exhibited no observable toxicity toward nematodes, even at higher concentrations. At the molecular level, RT-PCR analysis revealed that VEF treatment significantly downregulated key hypha- and biofilm-associated genes, including hwp1, als3, egf1, and cph1 suggesting interference with the major regulatory pathways governing morphogenesis and virulence. Overall, these findings indicate that VEF possesses promising antibiofilm and anti-hyphal activities and supports its preliminary antivirulence potential. Rather than suggesting direct therapeutic applications, this study highlights VEF as a candidate for further antivirulence and mechanistic investigations. In particular, the results support valencene as a potential antivirulence scaffold for future research aimed at addressing antifungal resistance and pathogenicity in C. albicans.\n\nID: 42547693\nTitle: Duloxetine repositioning: Investigation of antifungal and antibiofilm activity against fluconazole-sensitive and resistant Candida Spp. strains.\nAbstract: The increase in fungal infections, the limited therapeutic arsenal, and the emergence of resistance pose a global health problem. Candida spp. stand out as opportunistic pathogens that cause superficial and invasive diseases. Thus, the search for new therapeutic alternatives, such as drug repositioning, is necessary. Duloxetine (DUL), a serotonin-norepinephrine reuptake inhibitor antidepressant used to treat depression, has demonstrated antifungal activity and potentiates the effects of conventional antifungals in vitro. The objective of this study is to evaluate the in vitro activity of duloxetine (DUL) against resistant Candida spp. strains. To this end, the minimum inhibitory concentration (MIC) of DUL alone and in combination with conventional antifungals was determined in order to evaluate the type of interaction between them, as well as the minimum fungicidal concentration (MFC). The activity of DUL against mature and developing biofilms was evaluated, in addition to the possible antifungal mechanism of action. DUL showed MICs of 16 to 128\u00a0\u00b5g/mL with a fungicidal action profile, and when combined there was synergistic interaction with amphotericin B (AMB). In biofilms, DUL exhibited antibiofilm activity and enhanced AMB activity against developing, but not mature, biofilms. Mechanism of action analysis showed that DUL promoted oxidative stress, evidenced by increased reactive oxygen species (ROS) production, reduced GSH levels, mitochondrial depolarization, and phosphatidylserine externalization, suggesting the activation of the apoptotic pathway as a possible mechanism of cell death. The pro-oxidant effects of DUL were evident in C. albicans strains deficient in antioxidant defenses (cap1\u0394 and gpx3\u0394) compared to the wild-type strain. DUL exhibited antibiofilm activity and enhanced AMB activity against developing, but not mature, biofilms.\n\nID: 42543034\nTitle: The Mcu1 mitochondrial protein coordinates TCA cycle enzymes to modulate phenotypic switching and commensalism in Candida albicans.\nAbstract: Candida albicans is a common resident of humans that colonizes multiple sites in the human body, such as the gut, in healthy individuals. In immunocompromised hosts, however, it can switch to a pathogenic state and cause infections. The molecular mechanisms underlying this commensal-pathogenic transition have not been fully elucidated. Here, we demonstrate that the mitochondrial protein Mcu1, which is required for utilization of multiple carbon sources, plays a crucial role in N-acetylglucosamine (GlcNAc)-induced phenotypic switching and gut commensalism in C. albicans. Disruption of Mcu1 or key TCA cycle enzymes impaired GlcNAc utilization, blocked white-to-opaque switching under in vitro culture conditions, and reduced gut colonization in a murine model. Mechanistically, Mcu1 sustains respiratory metabolism by regulating key oxidoreductases, while also promoting gut commensalism by enabling in vivo activation of the master regulator Wor1. Collectively, our findings reveal that Mcu1 and key TCA cycle enzymes play an essential role in phenotypic switching and cooperatively regulate the commensal-pathogenic transition in C. albicans.\n\nID: 42536651\nTitle: Isolation and characterization of Candida metapsilosis from foci of chronic pododermatitis in captive steppe eagles in Kazakhstan.\nAbstract: Pododermatitis (bumblefoot) is a chronic, debilitating disease of the plantar surface of the foot that affects birds of prey kept in captivity worldwide. Although bacterial pathogens, especially Staphylococcus aureus, are most commonly considered as causative agents, the contribution of opportunistic yeasts to chronic, non-healing footpad lesions remains poorly characterized. Keratinophilic yeasts may sustain the disease process by degrading keratin in superficial tissues, impairing wound healing and, owing to their thermotolerance and minimal nutritional requirements, persisting in the environment of the bird's enclosure. In this study, three captive steppe eagles (Aquila nipalensis) from a single aviary in Kazakhstan, all presenting with chronic pododermatitis unresponsive to antibacterial treatment, were investigated by integrated mycological, biochemical and molecular approaches. The yeast isolates were recovered from the deep footpad lesions and identified to species level by sequencing of the ITS1-5.8S-ITS2 rDNA region. All these isolates were assigned to Candida metapsilosis, and phylogenetic analysis confirmed their close clustering with reference C. metapsilosis sequences. Phenotypic characterization showed that all isolates were thermotolerant (growth at 8-37 \u00b0C), expressed strong urease and keratinolytic activity (the latter confirmed in vitro by the hair perforation test), high saccharolytic activity and selective, weak proteolytic activity. Disk diffusion screening showed susceptibility to azoles (ketoconazole, clotrimazole, fluconazole) and reduced susceptibility to polyenes (nystatin, amphotericin B). To our knowledge, this is the first report of C. metapsilosis isolated from chronic pododermatitis lesions in captive steppe eagles. Combined with the documented in vitro virulence-associated traits and the resolution of the lesions following targeted antifungal therapy, our findings support a contributory etiological role of C. metapsilosis as an opportunistic pathogen in raptor pododermatitis in immunocompromised birds maintained under suboptimal husbandry. Mycological work-up, including molecular identification, is therefore warranted in cases of chronic, non-resolving pododermatitis in captive birds of prey.\n\nID: 42534992\nTitle: Hospital-acquired Candidozyma auris infections as an emerging threat in Saudi Arabia and Egypt: A narrative review on epidemiology and prevention strategies.\nAbstract: Candidozyma auris (C. auris) is an emerging multidrug-resistant pathogen increasingly associated in hospital-associated outbreaks, particularly in intensive care units (ICUs), and is classified by the World Health Organization as a critical priority pathogen. Its ability to persist in hospital environments, colonize patients asymptomatically, and exhibit multi-drug resistance to antifungal drugs poses a major challenge to infection prevention and control (IPC). This work is a synthesis of published, hospital-based evidence on nosocomial C. auris infections in Saudi Arabia and Egypt, with implications for antifungal stewardship, infection prevention, and control. Saudi Arabia and Egypt were selected because of their contrasting surveillance, healthcare capacities, and reporting intensities, which allow for comparative regional interpretation. This narrative review was conducted using PubMed and Google Scholar for English-language articles from 2020 to 2025, with key terms including \"Candida auris,\" \"C. auris,\" together with related concepts such as epidemiology, transmission, IPC, Saudi Arabia, Egypt, and drug resistance, with an emphasis on hospital-based studies. Available evidence indicates a marked increase in reported cases and outbreaks in Saudi Arabia, with risk factors of ICU exposure, invasive medical device use, and antibiotic use, whereas data from Egypt though limited increasingly suggest misdiagnosis and emerging local circulation in tertiary care settings. Both countries exhibit high fluconazole resistance and variable susceptibility to amphotericin B, with echinocandins as the preferred first-line therapy. These findings highlight the urgent need for enhanced surveillance, improved diagnostic capacity, and sustained, consistent IPC strategies in healthcare settings across the regions to limit further spread of C. auris.\n\nID: 42532402\nTitle: Candidemia in Post-COVID Era: Increasing incidence of endemic fluconazole-resistant Candida parapsilosis and Candidozyma auris.\nAbstract: To assess the effect of the COVID-19 pandemic on the epidemiology of candidemia. We retrospectively analyzed candidemia episodes diagnosed from 2018 to 2024 in a tertiary university hospital, evaluating incidence trends, species distribution, ward origin, antifungal susceptibility, and antifungal consumption in the context of the COVID-19 pandemic. Candidemia incidence remained high beyond the COVID-19 pandemic, particularly in intensive care unit. Candida parapsilosis species complex was the predominant pathogen, accounting for 41.4% in the post-COVID era, and exhibited persistently high fluconazole resistance rates of up to 64.3% together with increasing resistance to voriconazole. Increased azole resistance was associated with isolation from intensive care units. Candidozyma auris (Candida auris), first identified in 2022, rapidly became endemic, accounting for 29.5% of isolates in the post-COVID era and exhibiting uniform resistance to fluconazole. Candida albicans (18.5%) ranked as the third most frequently isolated species. Amphotericin B and echinocandins retained excellent in vitro activity, whereas the clinical utility of fluconazole was markedly reduced due to the high prevalence of resistant C. parapsilosis and C. auris. The COVID-19 pandemic was associated with a sustained increase in candidemia incidence, major shifts in species distribution, and high fluconazole resistance rates. These findings underline the need for ongoing surveillance and implementation of infection control measures.\n\nID: 42519881\nTitle: The metabolic trap: Candida parapsilosis inhibits Staphylococcus aureus biofilm maturation by disrupting pH homeostasis and inducing premature exodus.\nAbstract: Introduction. Hospital-acquired infections (HAIs) frequently manifest as device-related biofilms that exhibit enhanced tolerance to conventional therapies contributing to antimicrobial resistance. Polymicrobial biofilms involving Candida and Staphylococcus species are a major cause of persistent nosocomial infections. However, while the synergism between Candida albicans and Staphylococcus aureus is well-characterized, the interactions involving non-albicans Candida remain poorly understood.Hypothesis/Gap Statement. The specific interactions between Candida parapsilosis and S. aureus were entirely unknown, although it was broadly assumed they would be synergistic in nature, mirroring known Candida-Staphylococcus models.Aim. This study investigated the interspecies dynamics between C. parapsilosis and S. aureus within a mixed biofilm context.Methodology. C. parapsilosis secretome fractions were isolated and screened against methicillin-sensitive (MSSA) and methicillin-resistant (MRSA) S. aureus strains. Their effects on biofilm formation, primary attachment, planktonic growth and eradication were evaluated under varying glucose concentrations, followed by transcriptomic analysis of treated staphylococcal cells.Results. We report the discovery of a small (<10\u2009kDa), heat-stable fungal-secreted factor that significantly inhibits the maturation of MSSA biofilms and disperses preformed biomass without affecting primary attachment or planktonic growth, although MRSA strains remained recalcitrant. This antagonism is strictly glucose-dependent; the inhibitory effect is potent in 0.2% glucose but is abolished in both 0.5 and 1.0%\u2009glucose. Transcriptome analysis revealed that the fungal secretome triggers a pleiotropic 'Metabolic Trap' in S. aureus, characterized by the downregulation of the glycolytic pathway (e.g. tpiA, gapA) and a failure to induce critical-acid-tolerance systems, including the arginine deiminase and urease operons. This metabolic reprogramming maintains a near-neutral local pH (5.8-6), which in turn provides an optimal environment for the observed upregulation of staphylococcal nuclease (nuc) ultimately degrading the extracellular matrix and preventing the development of a mature biofilm architecture.Conclusion. We propose that the C. parapsilosis secretome effectively tricks S. aureus into a premature exodus phase, where nuclease-mediated matrix degradation prevents the establishment of a stable biofilm architecture. These findings underscore the highly species-specific nature of fungal-bacterial interactions and identify a specific metabolic vulnerability in S. aureus that may be exploited to develop novel anti-biofilm strategies against polymicrobial communities.\n\nID: 42515783\nTitle: Bioactive Silver Nanoparticles Synthesized Using Endophytic Bacillus subtilis CG1 and Their Antimicrobial and Antibiofilm Potential Against Drug-Resistant Pathogens.\nAbstract: Background/Objectives: The study addresses the global health challenge posed by multidrug-resistant (MDR) pathogens, highlighting the urgent need for alternative antimicrobial solutions. This study investigated the in vitro antimicrobial and antibiofilm potential of endophytic mediated-synthesized silver nanoparticles (AgNPs). Methods: An endophytic bacterium was isolated from the medicinal plant Commiphora gileadensis in Saudi Arabia and identified as Bacillus subtilis CG1 through 16S rRNA gene sequencing. The bacterium was utilized for the green synthesis of AgNPs, as confirmed by Ultraviolet-visible (UV-Vis) spectroscopy. AgNPs characterization was done using Fourier-transform infrared (FTIR) spectroscopy, Transmission and scanning electron microscopy (TEM and SEM), energy-dispersive X-ray spectroscopy (EDX), and dynamic light scattering (DLS). The antimicrobial efficacy of the fabricated AgNPs was tested against eight clinically relevant pathogens using standard in vitro assays such as the agar disk diffusion method, minimum inhibitory concentration (MIC), minimum bactericidal and fungicidal concentrations (MBC and MFC). Additionally, AgNPs were tested for antibiofilm activity against P. aeruginosa and S. epidermidis. Tested pathogens included Methicillin-Resistant Staphylococcus aureus (MRSA), Staphylococcus epidermidis, Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli, Candida auris, Candida albicans, and Candida tropicalis. The antibiofilm efficacy was tested using the Crystal violet assay. Results: UV-Vis spectroscopy confirmed AgNP formation with a characteristic absorption peak at 412 nm. FTIR analysis identified the presence of hydroxyl, nitrile, and alkyne functional groups, which are involved in nanoparticle reduction and stabilization. TEM and SEM revealed predominantly spherical AgNPs with sizes ranging from 17 to 72 nm, while EDX confirmed silver as the major elemental component. DLS analysis showed a Z-average particle size of 113.9 \u00b1 67.75 nm and a zeta potential of -24.2 mV. The synthesized AgNPs exhibited concentration-dependent antimicrobial activity, producing inhibition zones of 10-20 mm at 240 \u00b5g/mL. MIC values ranged from 6.25 to 25 \u00b5g/mL, whereas MBC and MFC values ranged from 6.25 to 50 \u00b5g/mL and 25 to 100 \u00b5g/mL, respectively. Moreover, bacterial growth kinetics analysis demonstrated a concentration-dependent inhibition of growth by AgNPs at MIC and sub-MIC concentrations. Additionally, AgNPs demonstrated significant antibiofilm activity against P. aeruginosa and S. epidermidis.Conclusions: Overall, B. subtilis CG1-mediated AgNPs exhibited promising physicochemical properties and antimicrobial and antibiofilm activities, suggesting their potential as alternatives for combating resistant and biofilm-associated infections.\n\nID: 42515075\nTitle: Vascular Notch-Related Protein Expression in a Rat Model of Central Venous Catheter-Associated Candida albicans Infection Under Antifungal and Prostaglandin-Pathway Interventions.\nAbstract: Central venous catheters are a major risk factor for Candida albicans vascular infections, which remain challenging to manage. Although antifungal therapy is standard, the host pathways shaping vascular responses-particularly the Notch signaling pathway (NSP)-are not well characterized in this context. In addition, the potential influence of the prostaglandin pathway on vascular NSP-related responses during infection remains unclear. In this study, a rat model of central venous catheter-associated C. albicans infection was used to evaluate microbiological outcomes and vascular NSP-related protein expression. Immunohistochemical analyses were performed to assess Candida immunostaining alongside the expression of Notch receptors (Notch1-3) and ligands (DLL1/4, Jagged1/2) in vascular tissues. Experimental groups included sham, infected control, antifungal-treated (fluconazole, caspofungin, liposomal amphotericin B), and prostaglandin pathway-intervention groups (sulprostone and sulprostone followed by indomethacin). C. albicans infection was associated with higher vascular NSP-related protein expression compared with sham animals. Antifungal-treated groups showed lower NSP-related protein expression, while fungicidal agents were associated with absence of fungal growth in catheter and kidney cultures. In the sulprostone-indomethacin-treated group, NSP-related protein expression levels were lower than those in the sulprostone-treated group despite persistent fungal burden. In conclusion, central venous catheter-associated C. albicans infection was associated with altered vascular NSP-related protein expression. Differences in NSP-related protein expression patterns were observed across antifungal- and prostaglandin pathway-intervention groups. These findings are descriptive and do not allow causal inference but may provide a basis for future studies exploring the role of NSP in vascular responses to C. albicans infection.\n\nID: 42515051\nTitle: Unmasking Candida viswanathii in Panel-Negative Candidemia Through Integrated MALDI-TOF MS and FTIR Spectroscopy.\nAbstract: Rare fungal infections may represent under-recognized causes of healthcare-associated sepsis, particularly when caused by emerging or difficult-to-identify pathogens. We aimed to characterize Candida viswanathii isolates recovered in the setting of panel-negative candidemia and to assess the contribution of an integrated diagnostic workflow. We investigated seven C. viswanathii isolates overall, including three recovered at our institution from blood, urine, and bronchoalveolar lavage of a NICU patient, as well as four bloodstream isolates from a second pediatric center included for comparison. Isolates were analyzed by culture and microscopy, three MALDI-TOF MS platforms, internal transcribed spacer sequencing, Fourier transform infrared (FTIR) spectroscopy and antifungal susceptibility testing. C. viswanathii was repeatedly recovered from blood, urine and bronchoalveolar lavage, while the FilmArray BCID2 panel remained negative. All MALDI-TOF MS systems with updated databases correctly identified the yeast at the species level; identification was confirmed by sequencing. Fourier transform infrared analysis showed clustering of clinical isolates and clearly separated C. viswanathii from related Candida species. All isolates exhibited low MICs to echinocandins and amphotericin B as well as moderately elevated fluconazole MICs (2-4 mg/L). This study supports the use of explicit diagnostic algorithms for rare fungal pathogens in yeast-positive, syndromic panel-negative blood cultures. In this setting, updated MALDI-TOF MS libraries and FTIR spectroscopy may provide useful adjunctive support for the recognition and phenotypic discrimination of atypical yeasts within an integrated laboratory workflow.\n\nID: 42511779\nTitle: Therapeutic Effects and Mechanisms of Sodium New Houttuyfonate in a Murine Model of Intra-Abdominal Candida albicans Infection.\nAbstract: Excessive use of immunosuppressive agents compromises host immune defenses and broad-spectrum antimicrobial drugs disrupts the normal microbiota, thereby promoting the overgrowth and dissemination of Candida albicans. As an opportunistic pathogen that commonly resides in the intestinal microbiota, C. albicans can subsequently translocate across the intestinal barrier and cause intra-abdominal infections. To investigate this process, a murine model of peritoneal C. albicans infection was established, in which sodium new houttuyfonate was administered for therapeutic evaluation. The therapeutic potential of sodium new houttuyfonate against abdominal C. albicans infection was evaluated through assessment of immune cell composition, peritoneal macrophage polarization, tissue fungal burden, and histopathological features. The molecular mechanisms of sodium new houttuyfonate therapy were also investigated with cellular experiments, including colony counting, real-time quantitative PCR, Western blotting, and the detection of reactive oxygen species (ROS) in RAW264.7 macrophages. Our results revealed that sodium new houttuyfonate exerts a dual anti-infective effect through its fungicidal activity and via the immunomodulation of immunoinflammatory states. Sodium new houttuyfonate also stimulates cytokine production (e.g., IL-1\u03b2, IL-6, IL-10, TNF-\u03b1, and MCP-1) via the TLR2/p38/NF-\u03baB pathway and promotes the release of ROS and nitric oxide. Overall, these findings highlight the potential of exogenous sodium new houttuyfonate as a therapeutic option for abdominal C. albicans infection.\n\nID: 42511468\nTitle: Candida albicans in Oral Squamous Cell Carcinoma: From Microbial Dysbiosis to Tumor-Promoting Mechanisms and Translational Opportunities.\nAbstract: Oral squamous cell carcinoma (OSCC) remains a major global health burden with limited improvement in survival rates. While traditional risk factors such as tobacco and alcohol are well established, increasing evidence highlights the role of the oral microbiome in carcinogenesis. Among microbial species, Candida albicans (C. albicans) has emerged as a potential contributor to tumor-promoting processes. Clinical studies consistently report increased fungal colonization in oral potentially malignant disorders and OSCC, with associations to disease severity and recurrence. Mechanistically, C. albicans contributes to carcinogenesis through acetaldehyde production, chronic inflammation, oxidative stress, epithelial signaling modulation, and extracellular vesicle (EV)-mediated communication. These pathways promote tumor microenvironment remodeling and epithelial transformation. However, conflicting evidence exists regarding causality, suggesting that fungal colonization may also result from tumor-associated ecological changes. From a translational perspective, C. albicans and EV-associated signatures may represent promising biomarkers and therapeutic targets, although further validation is required. This review highlights the emerging role of fungal-host interactions in OSCC and underscores their potential in microbiome-informed precision oncology.\n\nID: 42507176\nTitle: Efficacy and impact of hypocrellin B-mediated antimicrobial photodynamic therapy against biofilms of Candida albicans.\nAbstract: Candida albicans biofilms pose significant challenges in clinical settings due to their resistance to conventional antifungal treatments and their association with increased morbidity. This study aimed to evaluate the antifungal efficacy of hypocrellin B (HB)-mediated antimicrobial photodynamic therapy (aPDT) against biofilms formed by various strains of C. albicans, including standard, azole-sensitive, and azole-resistant strains. The effects of HB-aPDT on the viability, metabolic activity, and biomass of C. albicans biofilms were assessed using colony-forming unit (CFU) assays, XTT reduction assays, and crystal violet (CV) staining. Confocal laser scanning microscopy (CLSM) was used to observe changes in cell membrane integrity. The generation of reactive oxygen species (ROS) was analyzed using flow cytometry, and the impact on gene expression was examined using quantitative real-time PCR (qRT-PCR). HB-aPDT significantly reduced the survival of C. albicans biofilms in a dose- and light-dependent manner. CLSM revealed photodamage to cell membranes post-treatment, and an increased presence of ROS was observed in the treated biofilms. Gene expression analysis showed downregulation of virulence-related and ergosterol biosynthesis genes, indicating a potential disruption of key pathways in fungal pathogenesis. HB-mediated aPDT effectively reduced the viability and disrupted the structural integrity of C. albicans biofilms, including those resistant to conventional antifungals. This study highlights the potential of HB-aPDT as an innovative approach for managing drug-resistant Candida infections and offers a promising alternative to traditional antifungal therapies.\n\nID: 42506298\nTitle: Clinical Outcomes of Micafungin and Anidulafungin in Candidozyma auris (Formerly Candida auris) Candidemia: A Propensity Score-Matched Retrospective Cohort Study.\nAbstract: Candidozyma auris (formerly Candida auris) is a critical-priority multidrug-resistant pathogen. Comparative clinical data on first-line echinocandins-micafungin and anidulafungin-in C. auris candidemia remain limited. This retrospective cohort study compared clinical outcomes of micafungin and anidulafungin in adult patients with C. auris candidemia treated between January 2024 and December 2025 at three affiliated hospital campuses in Istanbul, T\u00fcrkiye. Propensity score matching (PSM) using a 1:1 nearest-neighbor algorithm was performed to balance baseline characteristics. Outcomes included 30-day (primary) and 14-day all-cause mortality, microbiological response, end-of-therapy (EOT) response, relapse, and drug-induced liver injury assessed by the Roussel Uclaf Causality Assessment Method (RUCAM). Among 154 included patients (micafungin, n = 94; anidulafungin, n = 60), no echinocandin resistance was detected. After PSM (55 matched pairs), 30-day all-cause mortality was identical between groups (41.8% vs. 41.8%; mOR 1.00, 95% CI 0.43-2.31; p = 1.000). Fourteen-day all-cause mortality (16.4% vs. 18.2%; p = 0.763), microbiological response (94.5% vs. 90.9%; p = 0.480), EOT response (74.5% vs. 67.3%; p = 0.346), and relapse (12.7% vs. 10.9%; p = 0.763) did not differ significantly between groups. RUCAM-based hepatic safety profiles were descriptively comparable. Micafungin and anidulafungin showed comparable observed outcomes in C. auris candidemia in this cohort.\n\nID: 42506280\nTitle: Risk Factors for Mortality in Candida auris Bloodstream Infection: A Multicenter Study in South Korea, 2018-2025.\nAbstract: Candida auris (C. auris) is a multidrug-resistant pathogen that spreads clonally in healthcare settings and was designated an urgent threat by the Centers for Disease Control and Prevention in 2019. We conducted a multicenter study to identify mortality risk factors in C. auris bloodstream infection (BSI) in South Korea. In this retrospective cohort study across three tertiary centers, 50 adults with first-episode C. auris BSI were analyzed. Primary and secondary outcomes were 30- and 90-day mortality. 30-day mortality was 24%, and 90-day mortality was 46%. Older age and higher Sequential Organ Failure Assessment score were independently associated with 30-day mortality. Microbiologic clearance within 30 days was protective. For 90-day mortality, older age was the only independent risk factor, and microbiologic clearance within 90 days was also protective. In conclusion, C. auris BSI causes substantial 30-day mortality, underscoring the need for risk-stratified, clearance-focused management.\n\nID: 42505599\nTitle: Changes in Antimicrobial Resistance Patterns in Intensive Care Units Following the COVID-19 Pandemic: A 10-Year Retrospective Study from T\u00fcrkiye.\nAbstract: The coronavirus disease 2019 (COVID-19) pandemic coincided with substantial changes in healthcare delivery and antimicrobial resistance (AMR) patterns worldwide, particularly in intensive care units (ICUs), where invasive procedures and broad-spectrum antibiotics are commonly used. Data from T\u00fcrkiye remains limited. This retrospective observational study evaluated bacterial and fungal isolates from adult ICU patients at a tertiary hospital from 2016 to 2025. Microorganisms were identified, and antimicrobial susceptibility testing was performed using standardized methods. Resistance patterns were compared between the pre-pandemic (January 2016-February 2020) and post-pandemic (March 2020-May 2025) periods. A total of 2666 patients and 5433 isolates were analyzed. Gram-negative pathogens showed marked increases in resistance: carbapenem and colistin resistance in Klebsiella pneumoniae were significantly higher in the post-pandemic period (69.6% vs. 44.4% and 60.5% vs. 22.5%, respectively; p < 0.001). Resistance rates to multiple antimicrobial agents also increased in Acinetobacter baumannii and Pseudomonas aeruginosa (p < 0.05). Among Gram-positive bacteria, vancomycin-resistant Enterococcus faecium increased from 10% to 47.1%. Candida auris emerged only in the post-pandemic period, showing high resistance to fluconazole (75%) and amphotericin B (36.7%). Significant differences in AMR patterns were observed between the pre- and post-pandemic periods in this ICU population. Higher resistance rates were observed among several clinically important bacterial pathogens, and Candida auris emerged exclusively during the post-pandemic period. Given the study's observational design, these findings should be interpreted as temporal associations rather than evidence of a causal effect of the COVID-19 pandemic. Continued antimicrobial stewardship and infection-control measures remain essential to address the growing burden of AMR.\n\nID: 42503186\nTitle: Integrated Approach for the Discovery of Antifungal and Antibiofilm Agents From Cerrado Plants.\nAbstract: The increasing incidence of Candida albicans infections, especially those involving drug-resistant strains, highlights the need for new antifungal agents. In this study, 108 plant extracts from native and endemic species of the Brazilian Cerrado were screened against C. albicans in both planktonic and biofilm forms (developing and mature). Eighteen extracts demonstrated significant antifungal and antibiofilm activity, particularly from species in the Fabaceae, Myrtaceae, and Celastraceae families. Extracts from Hymenaea stigonocarpa notably inhibited the yeast-to-hyphae transition, a key virulence factor. Using molecular networking (GNPS) and in silico tools (SIRIUS), 60 putative compounds were annotated, including xanthones, flavonoids and triterpenoids, with selected candidates showing favorable binding profiles in molecular docking analyses. This integrative metabolomic approach enabled the identification of bioactive scaffolds, reinforcing the Cerrado biome as a valuable source of structurally diverse metabolites for antifungal drug discovery.\n\nID: 42487897\nTitle: Divergence in surface protein exposure between reference and clinical-derived Candida glabrata (Nakaseomyces glabratus) strains (CBS138 vs. BG2) - a preliminary proteomic perspective.\nAbstract: Candida glabrata (currently classified as Nakaseomyces glabratus) is an opportunistic fungal pathogen notable for its intrinsic antifungal tolerance and ability to persist in host environments. Although strain CBS138 has served as the principal model for genetic and functional studies, accumulating evidence indicates substantial intraspecies diversity that may shape virulence, immune interactions and stress adaptation. In particular, the widely used clinical isolate BG2 differs from CBS138 in genome structure, adhesin regulation and macrophage survival, yet the extent to which these differences are reflected at the fungal cell surface remains unknown. Here, we present a comparative characterization of the surface-exposed proteomes (surfaceomes) of CBS138 and BG2 across three biologically relevant growth conditions: YPD-grown yeast-like cells, RPMI-cultured planktonic aggregates and RPMI-formed biofilms. Using trypsin shaving combined with LC-MS/MS, we identified pronounced strain- and condition-dependent differences in surface protein composition, encompassing adhesins, yapsin proteases and selected moonlighting proteins. Whereas CBS138 showed greater representation of adhesion- and interaction-related surface proteins, BG2 preferentially displayed proteins associated with cell-wall architecture and remodelling, consistent with distinct surface-mediated adaptive strategies. Transmission electron microscopy revealed condition-dependent differences in cell-wall thickness in both strains, with BG2 displaying a broader range of values and the highest thickness under biofilm conditions, providing structural context for variation in protease accessibility and surface-protein detectability. Collectively, our findings highlight substantial surfaceome plasticity in C. glabrata and underscore the importance of considering intraspecies diversity when interpreting host-pathogen interactions and fungal virulence pathways.\n\nID: 42487702\nTitle: Differentiation of Candida auris from other pathogenic yeasts using near-infrared spectroscopy and multivariate analysis: a proof-of-concept study.\nAbstract: Candida (Candidozyma) auris has emerged as a major public health concern due to its multidrug resistance, high mortality rates, and outbreak potential. These challenges are intensified by the difficulty of accurately identifying this species, particularly in settings with limited laboratory resources. This difficulty arises because C. auris is closely related to other yeast species, such as those within the Candida haemulonii complex. Although we previously demonstrated that near-infrared spectroscopy (NIRS) combined with multivariate analysis can discriminate C. auris from C. haemulonii stricto sensu, its performance against other clinically important yeasts had not been evaluated. In this study, we assessed NIRS coupled with different multivariate analytical techniques as a tool for distinguishing C. auris from C. haemulonii, C. albicans, C. tropicalis, C. parapsilosis, Nakaseomyces glabrata (formerly C. glabrata), and Pichia kudriavzevii (formerly C. krusei). Each of the seven species was cultured on fifteen Sabouraud Dextrose agar plates at 37 \u00b0C. After 72 h, three isolated colonies per plate (45 colonies per species) were subjected to Fourier-transform NIR analysis, resulting in a total of 315 spectra. The spectra were preprocessed and analyzed using principal component analysis (PCA), successive projections algorithm (SPA), genetic algorithm (GA), and linear discriminant analysis (LDA) to construct classification models. The combination of PCA, SPA, and GA with LDA achieved 100% sensitivity, specificity, and accuracy. These findings demonstrate that NIRS coupled with multivariate analysis can reliably differentiate C. auris from other medically important yeasts. The models also showed strong discriminatory capacity among the most prevalent pathogenic yeast species, reinforcing the promise of this approach as a rapid diagnostic tool for overcoming current identification challenges.\n\nID: 42486826\nTitle: [Rapid detection of fluconazole resistance in Candida tropicalis using MALDI-TOF mass spectrometry].\nAbstract: To evaluate the efficacy of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS)-based antifungal susceptibility testing (MS-AFST) for rapid detection of fluconazole resistance in Candida tropicalis. C. tropicalis isolates from patients with bloodstream infections at West China Hospital of Sichuan University (2018-2023) were collected and identified by chromogenic culture and MALDI-TOF MS. Using Clinical and Laboratory Standards Institute broth microdilution (BMD) method as the reference standard, we compared the performance of the Sensititre YeastOne chromogenic antifungal susceptibility testing and optimized MS-AFST based on the minimum profile change concentration (MPCC). All the 41 isolates were confirmed as C. tropicalis, which showed an azole resistance rate of 36.59% and a proportion of non-wild-type strain of 68.29% with high cross-resistance to azoles. The categorical agreement (CA) and essential agreement (EA) between Sensititre YeastOne and CLSI BMD were both 100%, and their minimum inhibitory concentrations were highly correlated. The MPCC-based MS-AFST enabled rapid detection of fluconazole-resistant phenotype of C. tropicalis within approximately 3 h, demonstrating a CA of 92.68% and an EA of 90.24% both in comparison with the CLSI BMD reference method and Sensititre YeastOne; very major error\\discrepancy occurred in two strains, and minor error\\discrepancy occurred in one strain. MPCC-based MS-AFST enables rapid, reliable detection of fluconazole resistance in C. tropicalis with good agreement with the reference methods. However, classification errors remain, which should be improved by further technical optimization of this method and exploration of the underlying molecular mechanisms. \u76ee\u7684: \u8bc4\u4f30\u57fa\u4e8e\u57fa\u8d28\u8f85\u52a9\u6fc0\u5149\u89e3\u5438\u7535\u79bb\u98de\u884c\u65f6\u95f4\u8d28\u8c31\uff08MALDI-TOF MS\uff09\u7684\u6297\u771f\u83cc\u836f\u7269\u654f\u611f\u6027\u8bd5\u9a8c\uff08MS-AFST\uff09\u5feb\u901f\u68c0\u6d4b\u70ed\u5e26\u5ff5\u73e0\u83cc\u6c1f\u5eb7\u5511\u8010\u836f\u6027\u7684\u4e34\u5e8a\u5e94\u7528\u6f5c\u80fd\u3002\u65b9\u6cd5: \u56de\u987e\u6027\u5206\u67902018~2023\u5e74\u56db\u5ddd\u5927\u5b66\u534e\u897f\u533b\u9662\u8840\u6d41\u611f\u67d3\u70ed\u5e26\u5ff5\u73e0\u83cc\u7684\u68c0\u51fa\u60c5\u51b5\uff0c\u5e76\u7ecf\u5ff5\u73e0\u83cc\u663e\u8272\u57f9\u517b\u4e0eMALDI-TOF MS\u884c\u83cc\u79cd\u9274\u5b9a\u3002\u6297\u771f\u83cc\u836f\u7269\u654f\u611f\u6027\u8bd5\u9a8c\u4ee5 CLSI \u5fae\u91cf\u8089\u6c64\u7a00\u91ca\u6cd5\uff08BMD\uff09\u4e3a\u53c2\u8003\u6807\u51c6\uff0c\u5bf9\u6bd4\u8bc4\u4f30 Sensititre YeastOne \u663e\u8272\u836f\u654f\u8bd5\u9a8c\u3001\u4f18\u5316\u524d\u5904\u7406\u540e\u57fa\u4e8e\u6700\u5c0f\u8c31\u56fe\u6539\u53d8\u6d53\u5ea6\uff08MPCC\uff09\u7684 MS-AFST \u6cd5\u68c0\u6d4b\u6c1f\u5eb7\u5511\u8010\u836f\u6027\u7684\u4e00\u81f4\u6027\u3002\u7ed3\u679c: \u672c\u7814\u7a76\u7eb3\u5165\u768441\u5206\u79bb\u682a\u5747\u4e3a\u70ed\u5e26\u5ff5\u73e0\u83cc\uff0c\u5176\u5511\u7c7b\u8010\u836f\u7387\u548c\u975e\u91ce\u751f\u578b\u83cc\u682a\u5360\u6bd4\u572836.59%~68.29%\uff0c\u4e14\u5511\u7c7b\u9ad8\u5ea6\u4ea4\u53c9\u8010\u836f\u3002Sensititre YeastOne\u4e0eCLSI BMD\u7684\u5206\u7c7b\u4e00\u81f4\u6027\u548c\u57fa\u672c\u4e00\u81f4\u6027\u5747\u4e3a100%\uff0c\u4e8c\u8005\u6700\u5c0f\u6291\u83cc\u6d53\u5ea6\u9ad8\u5ea6\u76f8\u5173\u3002\u57fa\u4e8eMPCC\u7684MS-AFST\u53ef\u4ee53 h\u5de6\u53f3\u5feb\u901f\u68c0\u6d4b\u70ed\u5e26\u5ff5\u73e0\u83cc\u6c1f\u5eb7\u5511\u8010\u836f\u8868\u578b\uff0c\u4e0eCLSI BMD\u53c2\u8003\u65b9\u6cd5\u548cSensititre YeastOne\u7684\u5206\u7c7b\u4e00\u81f4\u6027\u5747\u4e3a92.68%\uff0c\u57fa\u672c\u4e00\u81f4\u6027\u5747\u4e3a90.24%\uff0c\u6781\u91cd\u5927\u8bef\u5dee2\u682a\uff0c\u5c0f\u8bef\u5dee1\u682a\u3002\u7ed3\u8bba: \u57fa\u4e8e MPCC \u7684 MS-AFST \u53ef\u5feb\u901f\u68c0\u6d4b\u70ed\u5e26\u5ff5\u73e0\u83cc\u6c1f\u5eb7\u5511\u8010\u836f\u6027\uff0c\u4e14\u4e0e\u53c2\u8003\u65b9\u6cd5\u4e00\u81f4\u6027\u8f83\u597d\uff0c\u4f46\u4ecd\u5b58\u5728\u5206\u7c7b\u9519\u8bef\uff0c\u9700\u8fdb\u4e00\u6b65\u4f18\u5316\u65b9\u6cd5\u5e76\u63a2\u7a76\u5176\u673a\u5236\u3002.\n\nID: 42483585\nTitle: Wastewater-Based Epidemiology for Infectious Diseases: A New Trick for an Old Threat.\nAbstract: Wastewater-based epidemiology (WBE) is an innovative approach to epidemiology that offers unique opportunities for public health surveillance. Its potential had been recognized in various applications over the years, but it was the global scale of the response to the SARS-CoV-2 pandemic that truly brought WBE to the fore. In this perspective paper we explore the untapped potential of WBE as a catalyst for infectious disease surveillance and as a One Health epidemiological tool, and the future horizons and innovative applications of WBE. It is clear that WBE will address a growing number of pathogens of concern to human health, such as avian influenza viruses, mpox, enterovirus D68, Candida auris, and antimicrobial resistance. In addition, it will contribute to epidemic intelligence by monitoring mass gathering events, and by predictive modeling and forecasting in combination with artificial intelligence to mitigate and prevent infectious diseases from reaching the highest level of clinical complexity. We believe that the maximum performance and complete institutional integration into public health of WBE is yet to be realized on a global scale.\n\nID: 42475389\nTitle: An emergent biofilm program from inactivation of Candida albicans master regulators Efg1 and Ndt80.\nAbstract: Biofilm formation by the fungus Candida albicans is a central virulence trait that enables colonization of implanted medical devices and mucosal surfaces. Biofilm formation reflects a complex regulatory network, and depends upon multiple master regulators that include transcription factors Efg1 and Ndt80. It is well established that efg1\u0394/\u0394 and ndt80\u0394/\u0394 single gene mutants are defective in biofilm formation. We report here that an efg1\u0394/\u0394 ndt80\u0394/\u0394 double mutant of reference strain SC5314 is able to form a robust biofilm in vitro and in vivo. We refer to the efg1\u0394/\u0394 ndt80\u0394/\u0394 biofilm as an emergent biofilm because this phenotype could not have been predicted from the phenotypes of efg1\u0394/\u0394 or ndt80\u0394/\u0394 single gene mutants. In four additional strain backgrounds, efg1\u0394/\u0394 ndt80\u0394/\u0394 mutants do not form biofilms, but in all strain backgrounds the efg1\u0394/\u0394 ndt80\u0394/\u0394 mutants can form filamentous cells, which are components of biofilms. Emergent biofilm formation is especially pronounced in YPD\u2009+\u2009FBS medium at 30\u00b0C, and RNA-seq under those conditions reveals altered expression in the efg1\u0394/\u0394 ndt80\u0394/\u0394 double mutant of biofilm-related genes: upregulation of BCR1, UME6, and HGC1, and downregulation of ALS3, BRG1, and HWP1. These gene expression changes suggest that the emergent biofilm program is partially distinct from the conventional biofilm program. This inference is supported by functional analysis: emergent biofilm formation is independent of Brg1, Rob1, Tec1, and Wor3, all of which have positive roles in conventional biofilm formation. Emergent biofilm formation depends upon the hyphal cyclin Hgc1, the biofilm transcription factors Bcr1 and Ume6, and the Bcr1/Ume6-activated adhesin gene FLO9. The seemingly simple emergent biofilm program may represent a primordial surface colonization strategy.\n\nID: 42554499\nTitle: Biomolecular condensates in fungi: mechanisms and regulatory roles.\nAbstract: SUMMARYLiquid-liquid phase separation (LLPS) drives the formation of biomolecular condensates, a conserved phenomenon across eukaryotes. This process governs diverse cellular programs, from stress response and morphogenesis to disease pathology. Over the past two decades, the regulatory impact of biomolecular condensates in fungal biology has become increasingly recognized. In this review, we examine the fundamental molecular mechanisms driving LLPS, evaluate the current evidence for LLPS in macromolecular organization and cellular regulation in fungi, and outline the tools employed to study this phenomenon. Lastly, we highlight the challenges of bridging the gap between the in vitro behavior of biomolecular condensates and their complex regulatory functions in vivo within fungal biology.\n\nID: 42554495\nTitle: The Gti1/Pac2 family protein CFG1 controls fungal chlamydospore formation through orchestrating cell wall remodeling, lipid metabolism, and ribosome biogenesis.\nAbstract: The morphological transition of fungi from vegetative hyphae to thick-walled chlamydospores enhances their longevity in harsh environmental conditions. Owing to this resilience, pathogenic fungi that form chlamydospores are particularly difficult to control. Therefore, understanding the mechanisms of chlamydospore formation is critically important. Here, we show that the hyphae of the filamentous fungus Trichoderma guizhouense can differentiate into typical terminal and intercalary chlamydospores characterized by double-layered spherical or ellipsoidal cell walls with accumulated lipid bodies and nuclei. We found that during chlamydospore formation, ribosome biogenesis was gradually downregulated, indicating the entry of cells into dormancy. Comparative transcriptomic analyses across developmental stages and media identified the Gti1/Pac2 family protein CFG1 as an essential regulator, as the \u0394cfg1 strain failed to form chlamydospores under all inducing conditions. Lipidomic analysis showed its involvement in lipid metabolism, and mutants lacking lipid metabolism genes pdat or dgat produced fewer chlamydospores. Our work reveals the molecular mechanism of chlamydospore formation in T. guizhouense.IMPORTANCEIn fungal biology, the morphological transition from vegetative hyphae to thick-walled, lipid-rich chlamydospores represents a fundamental developmental switch into dormancy, crucial for survival under environmental stress. Understanding the regulatory mechanisms behind this process is essential for deciphering the basic principles of fungal cell differentiation and adaptation. This study employs multi-omics approaches to systematically characterize chlamydospore formation and identifies the Gti1/Pac2 family protein CFG1 as a master regulator. Functional analysis reveals that CFG1 governs this transition by directly influencing lipid metabolism-a key pathway for spore maturation and structural integrity. These findings uncover a previously unknown molecular switch in fungal development and provide new insights into how filamentous fungi coordinate metabolic reprogramming with cellular differentiation to ensure long-term survival.\n\nID: 42536052\nTitle: Mycoviruses at the Crossroads: Molecular Mechanisms, Cross-Kingdom Interactions, and Abiotic Stress in the Phytobiome.\nAbstract: Mycoviruses, viruses that infect fungi, have emerged as pivotal modulators of fungal biology with far-reaching consequences for plant health. Once regarded as mere curiosities of mycology, mycoviruses are now recognized as key players in tripartite mycovirus-fungus-plant interactions that reshape disease outcomes, endophytic lifestyles, and ecosystem resilience. Recent discoveries of cross-kingdom infection, core virome-mediated thermal tolerance, and reactive oxygen species (ROS) signaling hubs have substantially expanded our understanding of mycovirus biology. In parallel, mounting evidence implicates abiotic stressors-temperature fluctuations, drought, and elevated CO2-as critical yet underappreciated modulators of these tripartite interactions. This minireview synthesizes advances from 2018 to 2026, with emphasis on: (i) the expanding diversity and cross-kingdom capacity of mycoviruses, (ii) molecular mechanisms underlying hypovirulence, hypervirulence, and endophyte conversion, (iii) the emerging ROS-autophagy-RNA silencing signaling nexus, and (iv) how abiotic stress reshapes mycovirus-fungus-plant dynamics. We propose an integrative framework positioning mycoviruses as environmental sensors and ecological switches within the phytobiome, and identify critical knowledge gaps that must be addressed to harness mycoviruses for sustainable crop protection under climate change.\n\nID: 42506259\nTitle: The Mevalonate Pathway: Innovations, Applications, and Challenges in Biotechnology with Emphasis on Fungal Biology.\nAbstract: The mevalonate (MVA) pathway is a central metabolic route responsible for the biosynthesis of isoprenoids with broad biological and biotechnological relevance. Due to its importance, the MVA pathway has attracted increasing interest in studies of enzymatic regulation, structural biology, metabolic engineering, and synthetic biology, particularly in fungi. This review provides a comprehensive overview of the MVA pathway, addressing its distribution across different domains of life, evolutionary aspects, and metabolic organization, with emphasis in fungi. Special attention is given to the biochemical and structural characterization of MVA-pathway enzymes, including catalytic mechanisms, structural features, and regulatory processes. The methylerythritol phosphate pathway is also presented as an alternative route for isoprenoid precursor biosynthesis and discussed in terms of its taxonomic distribution and metabolic significance. Recent advances in synthetic biology, enzyme regulation, and pathway engineering are highlighted, emphasizing their contributions to metabolic engineering and synthetic biology. Special emphasis is given to fungi, in which the MVA pathway plays a central role in ergosterol biosynthesis, protein prenylation, and secondary metabolite production. Advances in the engineering of fungal cells, including Saccharomyces cerevisiae and other emerging fungal species, are discussed in the context of sustainable isoprenoid production. Finally, strategies for optimizing microbial production are presented, highlighting the importance of fungal synthetic biology in advancing biotechnological applications.\n\nID: 42481122\nTitle: Comprehensive analysis of southern corn rust (Puccinia polysora): morphology, host interactions, and molecular identification in maize.\nAbstract: Puccinia polysora, the causal agent of southern corn rust (SCR), poses a major threat to maize production, yet comprehensive studies under Indian conditions remain limited. This study provides an integrated analysis of the morphology, infection biology, molecular identity, and associated fungal microbiome of P. polysora. Microscopic investigations using stereoscopic, light, and scanning electron microscopy revealed detailed spore morphology and infection structures, including appressoria formation and intercellular colonization. Notably, hyphal anastomosis was observed, suggesting a potential mechanism for genetic exchange and pathogen adaptability. Molecular identification using basidiomycete-specific ITS primers (ITS1-F and ITS4-B) confirmed pathogen identity, supported by phylogenetic analysis. These findings significantly enhance our understanding of SCR pathogenesis and provide new insights into the biology and adaptability of P. polysora, opening new avenues for research on pathogen evolution and the development of effective strategies for disease management.\n\nID: 42481108\nTitle: Morphological characterization and phytotoxicity divergence of Elsino\u00eb arachidis causing peanut scab in China.\nAbstract: Peanut scab, caused by Elsino\u00eb arachidis, is a major disease in peanut-growing regions of China. To clarify the phenotypic characteristics and toxigenic divergence of the pathogen, 70 strains from major peanut-growing regions were subjected to morphological characterization, phylogenetic analysis, elsinochrome (ESC) quantification, and phytotoxicity assessment. Based on colony color, the strains were divided into five morphological groups (Group A-E), with the dark red pigmented Group D being dominant (50%). Growth rates varied among strains, with the coefficient of variation within each morphological group ranging from 10% to 25%, but no distinct pattern was observed across groups. All isolates were identified as E. arachidis and resolved within a species-level clade based on ITS and TEF1-\u03b1 phylogenetic analyses. ESC quantification revealed a significant correlation between colony color and toxin accumulation, with coral red and dark red strains (Groups A and D) accumulating higher ESC levels. Phytotoxicity assays demonstrated a significant positive correlation between lesion area and ESC accumulation (r\u202f=\u202f0.921, P\u202f<\u202f0.01). This study systematically characterized the intraspecific phenotypic differentiation of E. arachidis in China for the first time, establishing a correlation between pathogenic intensity, colony color, and ESC synthesis capacity. Furthermore, colony color was proposed as a visual phenotypic indicator for the rapid identification of highly virulent strains, and ESC accumulation was identified as the key metabolic process underlying phytotoxicity differentiation. These findings enhanced the understanding of population differentiation in E. arachidis and provide a theoretical basis for elucidating disease outbreak mechanisms and developing targeted control strategies.\n\nID: 42466666\nTitle: Candida auris in Europe: Epidemiology and antifungal resistance. A systematic review.\nAbstract: Candida auris is a widely distributed yeast that is considered a dangerous pathogen, with reported mortality rates ranging from 30% to 60%. This yeast shows a high level of resistance to several antifungal agents commonly used to treat systemic infections. The pathogen persists on contaminated surfaces, tolerates hospital-grade disinfectants, survives desiccation and spreads easily through direct or indirect contact. It has been reported on all five continents and is increasingly prevalent in Europe. To determine the distribution and antifungal susceptibility/resistance of Candida auris isolates identified in Europe until January 2025. This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Searches were conducted in EBSCOhost, MEDLINE/PubMed, Scopus and SciELO databases using the terms 'Candida auris' and 'Candidozyma auris', combined with the name of each European country. It was limited to English or Spanish articles published until 31 January 2025, excluding reviews, meta-analyses and book chapters. Ninety-one articles reporting antifungal susceptibility were retrieved, covering 2191 clinical isolates of C.\u2009auris from 16 countries. Most isolates were from Spain (n\u2009=\u2009886, 40.44%), Italy (n\u2009=\u2009553, 25.24%), Greece (n\u2009=\u2009214, 9.77%), the United Kingdom (n\u2009=\u2009182, 8.31%) and Russia (n\u2009=\u2009108, 4.93%), accounting for 88.68% of cases. The remaining 248 isolates (11.32%) were reported across 11 other countries. Fluconazole resistance was found in 90.51% (1555/1718), while resistance to amphotericin B and echinocandins was 13.17% (223/1693) and 4.57% (76/1693), respectively. Candida auris has been predominantly detected in Southern Europe, where the majority of clinical isolates exhibit resistance to fluconazole. Consensus is essential for timely diagnosis, targeted treatment and infection control to prevent its spread. New therapeutic options must be explored to manage Candida auris.\n\nID: 42460008\nTitle: In vitro and in vivo antifungal effects of fluconazole in combination with Cinnamomum verum essential oil against Candida spp.\nAbstract: Antifungal resistance in Candida species is a growing clinical problem globally, especially in immunocompromised patients. One of the alternative approaches to conventional therapies are currently based on essential oils (EOs) alone or in combination with antifungals. We aimed to evaluate the antifungal activity of Cinnamomum verum EO, alone and in combination with fluconazole, against reference and multidrug-resistant (MDR) Candida strains by in vitro and in vivo assays. The chemical composition of the EO was analyzed by gas chromatography-mass spectrometry. Antifungal activity was assessed by broth microdilution (minimum inhibitory concentration determination), while anti-adherence effects were evaluated using the microtitration with crystal violet. The fractional inhibitory concentration index and response surface approach were used to study synergistic interactions. The in vivo efficacy was assessed by tracking virulence factors, fungal load, and larval survival in Galleria mellonella model. The most significant phenylpropanoid components of the EO were (E)-cinnamaldehyde and eugenol. It demonstrated high antifungal activity and significantly decreased adherence to the inert substratum. The tested EO exhibited pharmacological synergy in combination with fluconazole, especially against fluconazole-resistant Candida auris strains. The optimized fluconazole-EO combination decreased fungal virulence and load, as well as G. mellonella larval mortality. C. verum EO exhibits strong anti-virulence and antifungal effects and increases fluconazole activity, indicating its potential as an adjuvant treatment against resistant Candida infections.\n\nID: 42453987\nTitle: The anti-Candida haemulonii activity and bioactive metabolites of Streptomyces anandii NC-SA6.\nAbstract: The rapid advancement of multi-omics strategies has profoundly facilitated the in-depth exploration of microbial physiological characteristics, accelerated the discovery of novel bioactive secondary metabolites, and promoted the mechanistic elucidation of their biological functions. As a dominant genus within the phylum Actinomycetota, Streptomyces is widely recognized for its remarkable capacity to synthesize a diverse spectrum of clinically applicable antibiotics. Candida haemulonii, an emerging opportunistic fungal pathogen, has emerged as a typical multidrug-resistant species closely associated with outbreaks of nosocomial infections, posing a severe threat to clinical antifungal therapy. In this study, a novel strain designated as Streptomyces anandii NC-SA6 was isolated and systematically identified via gradient dilution method, multilocus sequence analysis (MLSA), coupled with comprehensive physiological and biochemical characterization assays. The optimal fermentation condition was optimized by controling a single variable method and measuring the diameter of the inhibition zone. The antimicrobial spectrum was tested against a panel of pathogenic strains, and the MIC value was measured by using broth microdilution. Finally, antifungal compounds were analyzed by combnining genome and metabolomic. We identified a strain with a spectrum antimicrobial activity against human pathogenic Candida species and Gram-positive bacteria. The optimal fermentation conditions are 4-day fermentation broth in No. 6 medium, and the MIC values of S. anandii NC-SA6 fermentation broth for Candida auris BJCA001 and Candida haemulonii 190070, the MIC50 values were 36.8 mg/ml and 18.4 mg/ml, respectively. Whole-genome sequencing analysis revealed the presence of 20 biosynthetic gene clusters (BGCs) responsible for secondary metabolite biosynthesis. Untargeted metabolomic analysis identified a total of 1703 metabolites. Functional annotation demonstrated that 43.5% of these metabolites were characterized bioactive compounds, including antimicrobial agents, antifungal agents, antitumor inhibitors, and other pharmaceutical molecules; the remaining 56.5% were uncharacterized metabolites, indicating the existence of potential secondary metabolites. Collectively, this integrated multi-omics study identified S. anandii NC-SA6 as a promising microbial resource for mining antifungal metabolites targeting multidrug-resistant C. haemulonii, highlighting its tremendous potential for the discovery and developmental research of novel antifungal agents.\n\nID: 42439136\nTitle: [Invasive mycoses in France: what are the trends?].\nAbstract: The most frequent invasive mycoses in France are candidemia, Pneumocystis jirovecii pneumonia, and invasive aspergillosis. They occur primarily in immunocompromised patients. The risk of Pneumocystis pneumonia and cryptococcosis has notably decreased for people living with HIV through the past two decades. Patients with diabetes or an autoimmune disease represent an increasing proportion of these cases. Mortality of invasive mycoses is still high, particularly in cases of candidemia and invasive aspergillosis. Azole-resistant Aspergillus spp. isolates remain rare in France and the proportion of resistant strains in cases of invasive candidiasis is stable. The emergence of Candida auris, which is associated with outbreaks in healthcare facilities, is closely monitored. Except for candidemia, investigation of predisposing genetic conditions should mainly be conducted when invasive mycosis occurs in patients without any clear risk factor.

In a study of infected and colonized patients conducted between 1/17/2023 and 11/30/2023 at our medical center in North-Central Florida, whole-genome sequence data were obtained for 43 C. auris isolates from 36 patients. Thirteen (30%) of the 43 isolates were from cultures collected as part of an investigation of a possible infection, with blood (7 isolates) being the most common source; 8 (62%) of the 13 patients with clinical infections died. Isolates were within either a Clade I monophyletic subclade associated with European and Middle Eastern strains (n = 27) or were from Florida subclades within C. auris Clade III (n = 16). In 7 instances, multiple isolates with virtually identical genetic profiles were isolated from the same patient at time intervals that ranged from 3 weeks to 7 months, with, in some instances, intervening negative cultures. All isolates were resistant to triazoles, albeit with resistance mutations at different nucleotide positions and within different genes for Clade I and Clade III isolates. One Clade I isolate was resistant to echinocandins. Data are consistent with a point-source C. auris outbreak involving a Clade I subclade of possible European origin, combined with multiple introductions and transmission of Clade III isolates from Florida. Strains were able to persist for extended periods of time in colonized/infected patients.\n\nID: 42424280\nTitle: Candida species identified by MAL-DI-TOF and antifungal susceptibility in hospitalized patients with COVID-19 in Peru.\nAbstract: To identify Candida species using MALDI-TOF and analyze their antifungal susceptibility from Candida genus isolates in hospitalized patients with COVID-19 between November 2020 and April 2022. An observational, descriptive, and cross-sectional study based on the se-condary analysis of microbiological and clinical-epidemiological data from 260 Candida isolates, primarily from urine, respiratory secretions, and blood cultures, referred to the National Reference Laboratory of Mycology of the National Institute of Health. Identification was performed using phenotypic techniques and MALDI-TOF, and antifungal susceptibility was evaluated using disk diffusion and broth microdilution according to Clinical and Laboratory Standards Institute (CLSI) criteria. Candida albicans was the most prevalent species (64.6%), followed by Candida tropicalis, Candida glabrata, Candida parapsilosis, and Candida auris. Most isolates showed susceptibility to voriconazole and caspofungin, while varying percentages of susceptibility to fluconazole were observed, especially in C. glabrata and C. auris. Minimum inhibitory concentration (MIC) values showed variability between species and antifungals. Non-albicans species represented a considerable proportion of the analyzed isolates. These findings descri-be the pattern of species and antifungal susceptibility in strains referred to the National Reference Labora-tory of Mycology of the National Institute of Health during the COVID-19 pandemic.

In this three-year surveillance study (2022-2025), 357 non-duplicate Candida bloodstream isolates from a tertiary care centre in northern India were analysed to characterize species distribution, extracellular virulence phenotypes, virulence-associated genes, and antifungal susceptibility profiles. Species identification was performed using phenotypic methods and confirmed by PCR-RFLP and MALDI-TOF MS, while antifungal susceptibility testing followed CLSI M27-A3 guidelines. Non-albicans Candida species predominated (76.8%), with Candida tropicalis as the most frequent isolate, followed by Candida albicans and Candidozyma auris. Multiplex PCR demonstrated a high prevalence of virulence-associated genes (HWP1, ALS1, SAP2, and PLB1), with concordance between gene detection and phenotypic expression of adhesion, biofilm formation, and extracellular enzyme activity. Echinocandins retained potent in vitro activity across species, whereas C. auris exhibited a multidrug-resistant phenotype, including high fluconazole resistance and reduced susceptibility to amphotericin B and caspofungin. Species-stratified analyses revealed significant positive correlations between esterase and hemolysin activity and amphotericin B minimum inhibitory concentrations in C. albicans and C. tropicalis (p\u2009<\u20090.01). Multivariate analysis identified elevated amphotericin B MICs and specific virulence traits as independent predictors of strong biofilm formation. These findings highlight species-specific associations among virulence expression, genetic determinants, and the antifungal response, supporting integrated surveillance approaches to improve the management of invasive candidiasis.\n\nID: 42182103\nTitle: Defining the Candidozyma auris pan-genome and essentiality.\nAbstract: Candidozyma auris is an emerging multi-drug resistant fungal pathogen characterized by high mortality and rapid transmission in healthcare settings, but the genetic drivers of phenotypic variation between strains and the landscape of gene essentiality in this organism remain undercharacterized. Here, we integrate pangenomic analysis with global essentiality screening to establish a foundational understanding of the C. auris genome and identify potential therapeutic targets. We performed pangenome analysis on 695 outbreak strains of C. auris selected to be genetically representative of publicly sequenced genomes. After using BLAST to refine the pangenome, we found that 96.8% of gene families were core, with the remaining high-confidence accessory gene families primarily consisting of gene loss events or clade-specific genes. The high proportion of core genes emphasizes the clonal nature of these outbreak strains, but comparative analysis with the closely related C. haemuli species complex suggested that most of these core genes are functionally dispensible. To examine this hypothesis, we developed a novel insertional mutagenesis approach that leverages the promiscuous integration of linear DNA in the C. auris genome. This global analysis identified 614 high-confidence essential genes. Crucially, nearly one-third of these genes, including the conserved translation initiation factor Sui1, exhibit divergent essentiality patterns compared to the model yeasts Candida albicans and Saccharomyces cerevisiae. These findings highlight organism-specific biology that would be overlooked by orthology alone. By combining pangenomic diversity with functional essentiality, this study provides a comprehensive resource for identifying species-specific determinants of virulence and prioritizing novel targets for antifungal drug development.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

Baicalein (BE), a major bioactive constituent of Scutellaria baicalensis Georgi, exhibits notable antifungal potential, yet its specific molecular mechanisms against C. auris remain poorly elucidated. In this study, we determined the antifungal activity of BE against multiple C. auris isolates, assessed its effects on fungal growth, virulence attributes, adhesion, and biofilm development, validated its in vivo protective efficacy in a Galleria mellonella infection model, and explored the underlying mechanisms via transcriptomic sequencing. BE exerted potent and consistent antifungal activity against all tested strains, with a minimum inhibitory concentration of 1 \u03bcg/mL, minimum fungicidal concentrations of 4-8 \u03bcg/mL, and a sessile minimum inhibitory concentration of 32 \u03bcg/mL. It time- and concentration-dependently suppressed fungal growth, virulence factor expression, adhesion to biological and non-biological surfaces, and biofilm formation, while conferring significant in vivo protection against C. auris infection. Transcriptomic analysis identified 11 adhesion- and biofilm-associated target genes, among which SCF1 and ALS1 served as pivotal regulators. Collectively, BE exerts robust anti-C. auris effects by modulating key target gene expression to interfere with multiple virulence-related processes, providing experimental support for its development as a novel antifungal agent for C. auris infection treatment.IMPORTANCEThe emerging multidrug-resistant fungal pathogen Candida auris has become a critical global public health concern. Its pronounced nosocomial transmissibility, high infection-associated mortality, and extensive cross-resistance to mainstream antifungal agents have created substantial unmet needs in clinical treatment and nosocomial infection control. In this study, we systematically validated the in vitro and in vivo antifungal activity of baicalein against C. auris and elucidated the molecular mechanism underlying its modulation of virulence-related genes. Our findings provide a pivotal experimental basis for the development of novel antifungal therapeutics targeting C. auris infections.\n  --- END ACTUAL ABSTRACT FOR 42549922 ---\n\n- ERROR: You cited ID: 42537628 for the quote: \"Most concerning, C. auris clinical isolates demonstrate widespread and, in some cases, untreatable resistance to all antifungal drug classes.\"\n  FACT: Strict Misquote Detected!

Notably, it exhibits a unique ability to grow and persist on human skin, thus leading to efficient transmission through skin-to-skin contact. As a result, C. auris poses a significant risk of outbreaks in healthcare settings, especially in nursing homes that care for elderly patients. Most concerning, C. auris clinical isolates demonstrate widespread and, in some cases, untreatable resistance to all antifungal drug classes, including azoles, polyenes (amphotericin B), and echinocandins. Consequently, invasive C. auris infections cause high mortality rates (30-60%) even with antifungal therapy. Here, we provide a comprehensive overview of candidiasis caused by C. auris, discussing both host and pathogen determinants of skin colonization, as well as key challenges associated with preventing dissemination and management of disseminated fungal infections.\n  --- END ACTUAL ABSTRACT FOR 42537628 ---\n\n- ERROR: You cited ID: 42530613 for the quote: \"Deletion of RIP1, a conserved catalytic complex subunit, does not significantly alter the susceptibility to caspofungin or voriconazole.

Pronounced drug resistance makes treatment failure common, and so does antifungal tolerance, a phenomenon enabling pathogen survival at supra-MIC concentrations without resistance mutations. Here, we uncover a mechanism of antifungal tolerance in C. auris engaging the mitochondrial cytochrome bc1 complex. Deletion of RIP1, a conserved catalytic complex subunit, does not significantly alter the susceptibility to caspofungin or voriconazole. However, rip1\u0394 mutants exhibit a marked reduction in antifungal tolerance across a wide range of supra-MIC concentrations. Transcriptomics reveals the dysregulation of multiple drug resistance and tolerance-related genes in the rip1\u0394 mutant, demonstrating a role for Rip1 in controlling antifungal susceptibility. Targeting cytochrome bc1 function with the fungal-specific inhibitor Inz-5 enhances antifungal action of both voriconazole and caspofungin. Additionally, ablation of RIP1 causes fitness defects, suggesting that cytochrome bc1 is a potential antifungal target against C. auris infections.\n  --- END ACTUAL ABSTRACT FOR 42530613 ---\n\n- ERROR: You cited ID: 42499548 for the quote: \"biofilm-associated C. auris cells (sessile cells) exhibit MBECs 2- to 4,119-fold higher than planktonic MICs.\"\n  FACT: Strict Misquote Detected!

Analysis of 80 peer-reviewed studies reveals five principal findings: (1) C. auris exhibits clade-dependent geographic distribution and resistance profiles-Clade I (South Asia) and Clade III show fluconazole resistance exceeding 90%, whereas Clade IV exhibits 44% resistance; echinocandin resistance varies significantly by clade and no resistance was detected in certain clades; amphotericin B resistance varies from no detected resistance to 46% depending on clade; and pan-resistant strains have emerged; (2) biofilm-associated C. auris cells (sessile cells) exhibit MBECs 2- to 4,119-fold higher than planktonic MICs, representing a major driver of persistent colonization; (3) novel antifungal agents, including ibrexafungerp, manogepix (the active moiety of fosmanogepix), and rezafungin, demonstrate promising in vitro activity against C. auris, with manogepix showing the highest overall antibiofilm activity (geometric mean MBEC of 5.9 \u03bcg/mL) and ibrexafungerp demonstrating superior activity against Clade IV biofilms; (4) a tiered infection prevention and control (IPC) framework-integrating universal screening, contact precautions, and environmental decontamination-has been associated with reduced transmission rates in outbreak settings; and (5) climate change and global warming may have contributed to the emergence of C. auris through thermal adaptation of environmental fungal species. These findings indicate that effective mitigation of the C. auris threat requires integrated surveillance, susceptibility-guided therapy accounting for both planktonic and biofilm activity, and resilient healthcare systems adapted to the clade-specific epidemiology of this pathogen.\n  --- END ACTUAL ABSTRACT FOR 42499548 ---\n\n- ERROR: You cited ID: 42431934 for the quote: \"We identify recurrent CNV hotspots, with segmental duplications representing a predominant mode of genome variation.

While point mutations underlying antifungal resistance are well characterised, the contribution of structural genomic variation to antifungal responses remains poorly defined. Here, we integrate whole-genome sequencing, a genome-wide copy number variation (CNV) screen, electrophoretic karyotyping, and mutation-accumulation analyses to investigate the role of structural variation in antifungal susceptibility across a clinical cohort of C. auris isolates. We identify recurrent CNV hotspots, with segmental duplications representing a predominant mode of genome variation. Small duplications encompassing ERG11 arise at high frequency and frequently co-occur with drug resistance-associated ERG11 mutations, collectively enhancing azole resistance. In addition, large centromere-inclusive duplications of chromosome 1 generate supernumerary chromosomes, leading to paradoxical growth and reduced susceptibility to caspofungin, an echinocandin. At the population level, structural variants frequently arise in parallel to FKS1 mutations, suggesting multiple genetic mechanisms underlying reduced drug susceptibility. Together, our findings establish segmental duplication as a major, non-mutational driver of antifungal resistance, highlighting the need to consider structural genomic variation in both resistance surveillance and clinical susceptibility testing.\n  --- END ACTUAL ABSTRACT FOR 42431934 ---\n\n- ERROR: You cited ID: 42405804 for the quote: \"In C. auris, increased susceptibility of pseudohyphal cells occurred without overt transcriptional remodeling.\"\n  FACT: Strict Misquote Detected!

In this study, we demonstrated that the Neosartorya (Aspergillus) fischeri antifungal protein NFAP2 selectively targets early morphogenetic states of Candida albicans and Candidozyma auris, revealing a transient window of susceptibility during filament and pseudohypha formation. Integrated transcriptomic and in vivo analyses indicate that these developmental states may represent context-dependent entry points for NFAP2 activity. In C. albicans, transcriptomic and network analyses indicate the presence of an anabolic, translation-associated gene expression signature, accompanied by suppression of stress-protective pathways, which is associated with increased susceptibility of emerging hyphae to NFAP2 but does not establish a direct causal mechanism. In C. auris, increased susceptibility of pseudohyphal cells occurred without overt transcriptional remodeling, consistent with the characteristically muted gene expression responses of this species, suggesting that NFAP2 sensitivity is governed primarily by biophysical and post-transcriptional mechanisms rather than transcriptional reprogramming. Importantly, morphotype-specific vulnerabilities observed in vitro were reflected in distinct in vivo outcomes in Galleria mellonella, as NFAP2 was well tolerated and provided a moderate, transient survival benefit in pseudohyphal C. auris infections, but not in filamentous C. albicans, where a worsened outcome was observed, consistent with species- and morphotype-dependent activity. Taken together, these results suggest that early morphogenetic states of Candida are stress-sensitive phenotypes associated with increased susceptibility to NFAP2. This work provides a proof-of-concept framework for future investigation of morphotype-associated antifungal vulnerability to peptide-based antifungal strategies.IMPORTANCEDrug-resistant Candida species represent an escalating global health threat; however, most antifungal strategies continue to target fungal growth rather than intrinsic biological vulnerabilities. In this study, we identified early morphogenetic transitions as a shared window of increased susceptibility in both Candida albicans and the highly drug-resistant pathogen Candidozyma (formerly Candida) auris. By integrating transcriptomic profiling with in vivo infection models, we found that NFAP2 exhibits antifungal activity that is influenced by these transient developmental states in a context-dependent manner while remaining well tolerated by the host. We further demonstrated that morphotype-specific stress responses are associated with the divergent sensitivities of C. albicans and C. auris to NFAP2. These results support the concept that fungal morphogenesis may represent a therapeutically actionable process and provide a framework for designing antifungal strategies that target developmental states rather than growth. This strategy may open new opportunities for improving protein- and peptide-based therapies, as well as combination therapies against difficult-to-treat fungal pathogens.\n  --- END ACTUAL ABSTRACT FOR 42405804 ---\n\n- ERROR: You cited ID: 42405803 for the quote: \"This effect was also observed with other disease-causing Candida species, including emerging human pathogens Candida auris.\"\n  FACT: Strict Misquote Detected!

Human immunity to C. albicans infection is thought to be largely dependent on neutrophil reactive oxygen and nitrogen species (ROS/RNS) generation by neutrophils. Despite this, our understanding of innate immune killing and escape by C. albicans is primarily studied in macrophages, and the precise mechanisms of evasion are unclear in neutrophils. Here, we sought to determine the importance of neutrophil reactive nitrogen species (RNS) production during C. albicans infection in vivo. Using a zebrafish model, we found that C. albicans rapidly downregulated neutrophil RNS below basal levels during the first day post-infection, a time at which neutrophil RNS is upregulated in bacterial infections as an important host-defense mechanism, indicating fungal evasion of host neutrophils. We confirmed the downregulation of RNS in human primary neutrophils and with clinical Candida isolates, including emerging human pathogens Candida auris and Candida glabrata. Inducible nitric oxide synthase (iNOS; Nos2 in zebrafish), the enzyme responsible for RNS production, competes with the arginase enzyme for a shared substrate, L-arginine. Using a zebrafish arginase2 transgenic line and a C. albicans car1\u0394 mutant, we showed that both host and fungal arginase contribute to the reduction in neutrophil RNS. Despite pathogen downregulation, upregulation of neutrophil RNS via hypoxia-inducible factor 1\u03b1 (Hif-1\u03b1) stabilization was sufficient to improve host survival following C. albicans infection. Inhibition of Nos2 blocked the host protective effect of Hif-1\u03b1 stabilization. Finally, restoration of neutrophil RNS via Hif-1\u03b1 stabilization was additive to clinically relevant antifungal treatment, increasing survival and clearance of C. albicans infections. Together, these data demonstrate that restoration of the neutrophil RNS response in C. albicans infection improves infection outcomes, highlighting the potential of targeting Hif-1\u03b1 and RNS in host-directed therapies against fungal infections.IMPORTANCECandida albicans is a fungus that normally lives harmlessly in the human body but can cause life-threatening infections in people with weakened immune systems. A key part of the body's defense against this fungus is neutrophils, immune cells that kill microbes using toxic molecules. However, how Candida avoids neutrophil defense is not well understood. Here, we used zebrafish and human immune cells to show that Candida suppresses an important neutrophil defense, reactive nitrogen species (RNS), during infection. Unlike bacteria, which trigger RNS, Candida reduces these protective molecules to below normal levels, helping its survival. This effect was also observed with other disease-causing Candida species. We went on to show that both the host and Candida contribute to this suppression. Importantly, boosting the neutrophil response improved survival and helped clear infection, especially when combined with standard antifungal drugs. These findings suggest new ways to support the immune system alongside existing treatments.\n  --- END ACTUAL ABSTRACT FOR 42405803 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"NT-a9 is a novel triazole antifungal with potent activity against Candida and Cryptococcus species via strong inhibition of ergosterol biosynthesis.\" (Source: 42554648)\n- \"Exposure to supra-MIC TCZ (8-32 \u03bcg/mL) produced three phenotypic classes: Class 2 (TCZ-R, fluconazole-R) and Class 3 (TCZ-R, fluconazole-R, plus tolerance to caspofungin and micafungin).\" (Source: 42548818)\n- \"C. auris strains are classified into six distinct clades: South Asia, East Asia, South Africa, South America, Iran and Singapore.\" (Source: 42527656)\n- \"Sequencing identified Y132F mutations in the ERG11 gene of the three clinical strains.\" (Source: 42513906)\n- \"Functional analyses demonstrated that deletion of HAC1 increased sensitivity to endoplasmic reticulum stress.\" (Source: 42370646)\n- \"Proteomic profiling revealed that C. auris mounts distinct but overlapping adaptive responses to antifungal stress, involving stress response pathways, metabolic reprogramming and amino acid biosynthesis.\" (Source: 42369549)\n- \"Clade I (South Asian) and Clade IV (South American) represent the highest clinical risk due to hyper-virulence and high rates of multi-drug resistant (MDR) strains.\" (Source: 42348119)\n- \"Resistance patterns have evolved from predominantly azole resistance to broader multidrug-resistant phenotypes, including treatment-emergent echinocandin resistance.\" (Source: 42346566)\n- \"Candida auris emerged only in the post-pandemic period, showing high resistance to fluconazole (75%) and amphotericin B (36.7%).\" (Source: 42505599)\n- \"C. auris DNA was detected in one sample (1.25%), specifically from the Gediz Delta (Sample No. 5651, 38.523\u00b0 N, 26.892\u00b0 E), with Ct values 33.8-37.2 confirmed by sequencing.\" (Source: 42470541)\n- \"Antifungal-treated groups showed lower NSP-related protein expression, while fungicidal agents were associated with absence of fungal growth in catheter and kidney cultures.\" (Source: 42515075)\n- \"Fluconazole resistance was found in 90.51% (1555/1718), while resistance to amphotericin B and echinocandins was 13.17% (223/1693) and 4.57% (76/1693), respectively.\" (Source: 42466666)\n- \"To examine this hypothesis, we developed a novel insertional mutagenesis approach that leverages the promiscuous integration of linear DNA in the C. auris genome.

Its biological success is rooted in a robust, multi-faceted adaptive capacity. Recent molecular research identifies distinct genomic strategies employed by the pathogen to navigate therapeutic pressure. Specifically, structural variations, such as those within the ERG11 locus, drive azole resistance, while supernumerary chromosomes contribute to echinocandin tolerance. Furthermore, internal regulatory systems, including the unfolded protein response and specific mitochondrial complexes, enable C. auris to maintain viability under host-imposed stress. The pathogen\u2019s ability to manipulate the host immune environment\u2014specifically by suppressing reactive nitrogen species\u2014underscores its sophisticated virulence. Surveillance data indicate that environmental reservoirs and hospital-associated colonization remain primary drivers of dissemination.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   C. auris employs non-mutational mechanisms of resistance, specifically segmental duplications of genomic regions, to circumvent antifungal activity.\n*   The pathogen displays clade-specific geographic distribution and resistance profiles, complicating universal treatment protocols.\n*   C. auris can persist on non-living environmental surfaces and skin, exhibiting tolerance to standard hospital disinfectants.\n*   A significant proportion of the C. auris genome consists of core gene families, yet many are functionally dispensable under experimental conditions.\n*   C. auris exhibits a unique ability to manipulate host neutrophil responses by suppressing reactive nitrogen species (RNS) production.\n*   Environmental surveillance has detected C. auris DNA in surface waters, indicating potential reservoirs outside traditional clinical settings.\n*   Cross-kingdom interactions (e.g., mycoviruses) and abiotic stress may influence the thermal tolerance and fitness of the pathogen.\n*   Phenotypic variation in C. auris frequently results in misidentification by standard diagnostic automated systems, often being mislabeled as other yeast species.\n*   Early morphogenetic states of C. auris represent a transient vulnerability to specific antifungal proteins.\n*   The metabolic regulation by mitochondrial proteins is critical for tolerance, with specific deletions leading to fitness defects.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Prospective observational surveillance study. Tertiary academic hospital in Northern Greece. Hospitalized patients undergoing active MDRO screening based on predefined infection prevention and control criteria. A pathogen-focused analysis was conducted using data from a prospective MDRO surveillance program between October 2024 and January 2025. Screening swabs were obtained from the rectum and groin. Target organisms included multidrug-resistant (MDR) Klebsiella pneumoniae, Pseudomonas aeruginosa, vancomycin-resistant enterococci (VRE), Candida auris, and Acinetobacter spp. Pathogen-specific detection yields were calculated for each anatomical site. Among 1,206 screening swabs, 308 (25.5%) were positive for at least one MDRO. Rectal swabs detected 95.8% of Klebsiella pneumoniae (K. pneumoniae) (92/96), 100% of VRE (59/59), and 66.7% of Pseudomonas aeruginosa (46/69). In contrast, 88.9% of Candida auris cases (24/27) were identified exclusively from groin swabs. Reliance on rectal screening alone would have missed nearly 90% of Candida auris carriers, whereas groin-only screening would have failed to detect most K. pneumoniae and all VRE carriers. Anatomical site selection critically influences MDRO surveillance sensitivity. Rectal screening is optimal for MDROs colonizing the gastrointestinal tract, whereas groin sampling is essential for detecting Candida auris. Pathogen-targeted, site-specific surveillance strategies may substantially improve detection efficiency and optimize infection prevention efforts in high-prevalence hospital settings."

Genomic analyses show that the clinical isolates with enhanced biofilm formation ability carry a loss-of-function mutation in the WOR2 locus, which encodes a white-opaque switching regulator in Candida species. Analysis of 13,314 published genomes revealed that 3104 strains (23.3%) harbor nonsense or frameshift mutations in WOR2, indicating frequent clinical occurrence. Deletion of WOR2 in a clinical strain markedly increased biofilm formation, whereas reintroduction of an intact WOR2 significantly attenuated biofilm development. Further analyses show that Wor2 inactivation upregulates GFC1, ALS4, and multiple biofilm-associated genes. Together, these findings reveal a key regulatory mechanism underlying biofilm development, environmental persistence, and transmission of C. auris."

Its pathogenicity, capacity for skin colonization, environmental persistence, and resistance to antifungal drugs and disinfectants have all contributed to its consolidation as a leading cause of healthcare-associated outbreaks. Nevertheless, increasing evidence indicates that C. auris should not be viewed solely as a nosocomial yeast, but rather as part of a broader environmental continuum encompassing natural habitats, anthropogenic niches, and multiple host species. Environmental isolates have been documented in coastal wetlands, wastewater systems, agricultural products, as well as in diverse animals - including companion animals, reptiles, amphibians, and insects - supporting its classification as a sapronotic pathogen. The near-simultaneous emergence of distinct clades across continents strongly suggests that climate change, agricultural azole exposure, and ecological adaptation have collectively selected strains exhibiting thermotolerance, antifungal resistance, and cross-kingdom persistence, thereby enabling recurrent spillover into human populations. Recent advances in wastewater-based epidemiology demonstrate that C. auris can be detected at the community level, often preceding clinical recognition, while animal colonization underscores its overlooked role in pathogen maintenance and transmission networks. This review synthesizes current evidence on the ecological, evolutionary, and epidemiological determinants of C. auris, positioning outbreaks as amplification phenomena within interconnected ecological systems rather than isolated nosocomial events. Adoption of a One Health framework, integrating environmental, veterinary, and human health surveillance, will be essential for predictive outbreak modeling, early detection, and the development of sustainable strategies to mitigate the ongoing and future threats posed by this emerging fungal pathogen."

Although echinocandin resistance in Candida is typically associated with fitness loss, we found that micafungin-resistant C. auris strains (MICAevo) generated from two distinct source isolates (AR0381 and AR0387) via experimental microevolution retained full virulence. Evolved strains developed stable resistance to multiple echinocandins, while AR0387 (B8441), originating from MICAevo strain, also acquired increased azole tolerance. Whole-genome sequencing revealed clinically relevant mutations in FKS1, as well as changes in genes involved in ergosterol biosynthesis (ERG3), amino acid metabolism, and PKA signaling. Despite in vitro sensitivity to cell wall stressors, resistant strains maintained or even enhanced colonization in a murine systemic infection model. Independently evolved strains showed similar antifungal resistance profiles, and although minor differences of pathogenic potential were noted, no consistent virulence attenuation was observed, indicating the reproducibility of phenotype changes. These findings suggest that C. auris can acquire echinocandin resistance without compromising pathogenicity, supporting its persistence and spread in clinical settings."

Baicalein (BE), a major bioactive constituent of Scutellaria baicalensis Georgi, exhibits notable antifungal potential, yet its specific molecular mechanisms against C. auris remain poorly elucidated. In this study, we determined the antifungal activity of BE against multiple C. auris isolates, assessed its effects on fungal growth, virulence attributes, adhesion, and biofilm development, validated its in vivo protective efficacy in a Galleria mellonella infection model, and explored the underlying mechanisms via transcriptomic sequencing. BE exerted potent and consistent antifungal activity against all tested strains, with a minimum inhibitory concentration of 1 \u03bcg/mL, minimum fungicidal concentrations of 4-8 \u03bcg/mL, and a sessile minimum inhibitory concentration of 32 \u03bcg/mL. It time- and concentration-dependently suppressed fungal growth, virulence factor expression, adhesion to biological and non-biological surfaces, and biofilm formation, while conferring significant in vivo protection against C. auris infection. Transcriptomic analysis identified 11 adhesion- and biofilm-associated target genes, among which SCF1 and ALS1 served as pivotal regulators. Collectively, BE exerts robust anti-C. auris effects by modulating key target gene expression to interfere with multiple virulence-related processes, providing experimental support for its development as a novel antifungal agent for C. auris infection treatment.IMPORTANCEThe emerging multidrug-resistant fungal pathogen Candida auris has become a critical global public health concern. Its pronounced nosocomial transmissibility, high infection-associated mortality, and extensive cross-resistance to mainstream antifungal agents have created substantial unmet needs in clinical treatment and nosocomial infection control.

Here, we investigated whether laboratory exposure of a clade III clinical C. auris isolate to TCZ could induce cross-resistance to clinical antifungals. Among 17 agrochemicals tested, only TCZ exhibited intrinsic antifungal activity. Brief (48 h) exposure to sub-MIC TCZ (1 \u03bcg/mL) selected variants (6.9% frequency) with cross-resistance to TCZ and fluconazole, but full susceptibility to caspofungin. Exposure to supra-MIC TCZ (8-32 \u03bcg/mL) produced three phenotypic classes: Class 2 (TCZ-R, fluconazole-R) and Class 3 (TCZ-R, fluconazole-R, plus tolerance to caspofungin and micafungin). The frequency of Class 3 increased dose-dependently from 23% to 50% as TCZ concentration rose. RNA-Seq revealed that both classes overexpressed MDR1, TAC1b, UPC2 and FKS1, but Class 2 showed broad ergosterol pathway upregulation, whereas Class 3 exhibited restricted ergosterol activation but downregulation of the sole chitinase gene CHT1 (5.17-fold), a known mechanism of echinocandin tolerance. Unlike the CRS-MIS phenomenon in Candida glabrata, our Class 3 adaptors displayed equal tolerance to both caspofungin and micafungin. Collectively, these findings demonstrate that, in a clade III clinical isolate of C. auris under the tested laboratory conditions, laboratory exposure to an agricultural triazole can rapidly select for clinically relevant azole cross-resistance and echinocandin tolerance in C. auris, suggesting that environmental fungicide use may inadvertently compromise the efficacy of last-line antifungals."

Distinct from other clinically prevalent fungal pathogens such as Candida species, C. auris employs unique defense mechanisms against the host immune system, including immune evasion and survival strategies. This review summarizes the distinct strategies used by C. auris to resist host immune responses. In particular, C. auris exhibits pronounced genomic and morphological plasticity, which facilitates rapid adaptation to host-derived stressors. Its modified cell wall, characterized by a thicker mannan layer, efficiently masks immunogenic \u03b2-glucan, thereby reducing immunogenicity. Furthermore, multicellular features, including robust biofilms and unique aggregative forms, enhance colonization, transmission, and stress resistance. C. auris also secretes diverse virulence factors and undergoes adaptive metabolic reprogramming under nutrient limitation, promoting more efficient immune evasion and survival within the host. Collectively, these flexible defensive strategies confer enhanced host immune resistance, contributing to its heightened pathogenicity. This review provides novel perspectives on future research directions and potential therapeutic strategies for managing C. auris infections."

This rapid expansion is defined by its unique population structure consisting of six distinct genomic clades with starkly different evolutionary trajectories, phenotypic traits, and clinical risks. We conducted a systematic synthesis of literature from PubMed, Scopus, and Google Scholar (2009-2026), focusing on comparative genomics, clade-specific virulence, and diagnostic accuracy. A total of 64 studies were analyzed to identify patterns in clade divergence and antifungal resistance. Our analysis reveals that C. auris is not a monolithic threat but a complex of diverse lineages with specialized adaptations. Clade I (South Asian) and Clade IV (South American) represent the highest clinical risk due to hyper-virulence and high rates of multi-drug resistant (MDR) strains. In contrast, Clade II (East Asian) was initially associated with localized ear infections; recent genomic data show an expanding pathogenic profile with emerging bloodstream infections. Our review also identifies Clade V (Iranian) as a genetically distinct group and highlights the recent identification of Clade VI (Indomalayan) as a distinct lineage, suggesting a long-standing environmental reservoir. Furthermore, we identify critical \"blind spots\" in automated diagnostic platforms (VITEK\u00ae 2, BD Phoenix) where phenotypic variations in Clades II and III lead to frequent misidentification as Candida haemulonii or Candida famata. This review proposes a \"clade-aware\" framework for public health. While frontline antifungal treatment remains standardized regardless of lineage, we argue that effective long-term management and outbreak containment require integrating genomic surveillance with clade-specific infection control. By identifying high-biofilm clades (Clade I) or hyper-virulent lineages (Clade IV), public health systems can implement more targeted containment strategies, moving toward a precision-based approach to managing this fungal pathogen."

The Centers for Disease Control and Prevention (CDC) has designated it as a pathogen of concern. The World Health Organization (WHO) has listed it in priority list of fungal pathogens. C.\u00a0auris has the ability to spread very fast inside the hospital environment and cause outbreaks worldwide. It has a very high affinity toward skin colonization, especially in the areas like axilla and groin. Based on whole genome sequencing it is classified into five clades. Each clade has different geographical distribution. Often C. auris gets misidentified as other species due to its phylogenetic similarity with C.\u00a0heamulonii. This can only be resolved by establishing diagnosis at molecular levels. Whole genome sequencing and polymerase chain reaction are some of the important molecular diagnostic methods for detection of C. auris. MALDI-TOF-MS is a culture based highly efficient method that is widely being used for C. auris identification. Treatment of C. auris infection depends on effective antifungal therapy, as multidrug resistance is quite common, the drug regime is decided after antifungal sensitivity testing. It is commonly treated with echinocandins and polyenes. Apart from the antifungal therapy it is also important to monitor the fungemia by performing blood cultures. A strict surveillance system can help prevent the disease. Timely screening of hospital personnel carrying the yeast can contain the spread of this organism. Newer antifungal agents are also required as the organism develops resistance very fast."

Despite the recent emergence of at least four distinct clades at the global scale, little remains known about how C. auris is so adept at growing on skin and the key genes and pathways it utilizes to metabolize the scarce nutrients available. Here, we identify the roles that conventional and alternative carbon metabolism genes and metabolic pathways have in facilitating C. auris growth through laboratory-based experiments and bioinformatics analyses. In artificial skin-like media, all four clades of C. auris were more capable of growing than Candida albicans SC5314, a clinically relevant counterpart. By investigating the differential regulation of C. auris when growing in skin-like media as compared to rich fungal media, we uncovered hundreds of genes in multiple metabolic pathways. To further test the mechanisms of these metabolic pathways, we deleted several non-essential gene candidates including FOX2 (B9J08_002847), CAT2 (B9J08_000010), and ICL1 (B9J08_003374). The mutant strains all exhibited abrogated growth in skin-like media and demonstrated nutrient preferences that differed from the wild type. Thus, we propose a model of how C. auris has the capacity to metabolize nutrients that are available on skin by optimizing its metabolic profile. Targeting these metabolic pathways to mitigate C. auris growth on skin is a potential avenue to explore in controlling the spread of this emerging human fungal pathogen. Candida auris is an emerging fungal pathogen with human skin as its primary site of colonization and subsequent transmission. Here, we show the importance of conventional and alternative carbon metabolism for the ability of C. auris to grow in artificial skin-like media. This knowledge provides a better understanding of C. auris metabolism and sheds light on genes and pathways that could be targeted to interfere with persistent skin colonization."

This fungal pathogen is notable for its thermotolerance and a strong attachment capability that confers environmental persistence and immune evasion. Here, we compared strains from five clades of C. auris: clade I = South Asia (CDC 387), clade II = East Asia (CDC 381), clade III = Africa (CDC 384), clade IV = South America (CDC 385), and clade V = Iran (CDC 1097) for their ability to regulate cell surface hydrophobicity and biofilm. The hydrophobicity varied for each C. auris clade, with strains 384, 385, and 1097 displaying the highest hydrophobicity levels. C. auris strains had variable biofilm levels when compared among clades and had lower or similar biofilm levels when compared with Candida albicans at different temperatures. Comparison of mass spectrometry analysis of proteolytic digestates of cells from strains with low or high hydrophobicity revealed putative surface hydrophobic proteins. These included homologs to Candida albicans Als3 and IFF proteins, and their contribution to hydrophobicity and biofilm formation was confirmed with gene-deficient (knockout) C. auris strains. We conclude that several proteins contribute to C. auris surface hydrophobicity. Candidozyma auris (Candida auris) is an emerging pathogenic microorganism that is rapidly gaining attention due to outbreaks in health care facilities and its multidrug resistance. Its origin has yet to be determined, but genotypic analyses have pointed toward a simultaneous independent emergence of the different clades, possibly implicating climate change as a major factor in its recent appearance as a fungal pathogen. In 2022, the World Health Organization placed C. auris in the critical priority group as the second greatest fungal threat globally. Due to limited immunological and proteomic studies of C. auris, we sought to elucidate possible virulence mechanisms and identify leading proteins that can be targeted by immunotherapies and new drugs. Using proteomic analysis, we identified 12 lead proteins related to C. auris hydrophobicity and adhesion, implying that these properties are conferred by multiple proteins."

These traits enable it to persist and be continuously transmitted in the environment, posing significant challenges for preventing and controlling clinical infections. Our study aimed to elucidate the phylogenetic relationships of C. auris isolates collected in China, and to explore the tolerance of C. auris to antifungal drugs and disinfectant agents commonly used in hospital. This study also intended to comprehensively characterize the drug resistance genes and amino acid substitutions in C. auris. METHODS: Whole-genome sequencing was used to identify and construct a phylogenetic tree for 8 strains of C. auris. The minimum inhibitory concentration (MIC) and minimum bacterial concentration (MBC) of antifungal agents against C. auris isolates were determined using broth dilution. Quantitative suspension tests were conducted to evaluate the killing effects of different disinfectant agents on C. auris isolates. Resistance genes and mutation sites were identified using bioinformatic analysis. RESULTS: Five isolates of C. auris were closely related to the C. auris B13916 (clade I) and three isolates were closest to B17721 (clade III). All isolates showed resistance to fluconazole; five of them showed reduced susceptibility to amphotericin B. Compared with Candida albicans, benzalkonium chloride, didodecyl dimethylammonium chloride, chlorhexidine gluconate, and hydrogen peroxide showed increased MIC and MBC values against C. auris isolates. Under specific conditions, the anti-fungal effects of benzalkonium chloride, chlorhexidine gluconate, sodium hypochlorite, ethanol, and povidone-iodine were effective. however, didodecyl dimethylammonium chloride and hydrogen peroxide were less effective. C. auris isolates exhibited amino acid substitutions in ERG11, ERG2, ERG4, CIS2, TAC1, and CDR1. They also possessed resistance genes associated with antimicrobial target alterations and efflux pump. CONCLUSIONS: The decreased susceptibility of C. auris to fluconazole, amphotericin B, didodecyl dimethylammonium chloride, and hydrogen peroxide, which could be attributed to resistance genes and single-nucleotide mutations, reminds medical institutions to rationally select the type, concentration, and exposure time of antifungal agents targeting C. auris. The emergence of C. auris resistance to antifungal drugs and disinfectant agents may involve common molecular mechanisms involving nucleotide mutations, requiring further studies."

In this study, we report the synthesis, characterization, and biological evaluation of a guar gum-quercetin bioconjugate designed to improve the practical applicability of quercetin through covalent conjugation with a biocompatible polysaccharide scaffold and a cystamine-based disulfide linker. The formation of the GG-Cys-Quer conjugate was supported by FTIR, 1H/13C NMR, CHNS elemental analysis, degree-of-substitution estimation, SEM, and TGA. The conjugate showed potent antifungal activity against five clinical C. auris isolates, with MIC and MFC values ranging from 0.030 to 0.245 \u00b5g mL-1 and 0.123 to 0.488 \u00b5g mL-1, respectively. Against the resistant isolate MRL6057, GG-Cys-Quer showed an MIC of 0.245 \u00b5g mL-1, whereas caspofungin showed an MIC of 4.0 \u00b5g mL-1 under the same assay conditions. Mechanistic studies showed increased intracellular ROS accumulation, loss of mitochondrial membrane potential, and apoptosis-associated changes, as confirmed by Annexin V/PI staining, with a concentration-dependent increase in late apoptotic/necrotic cell populations at higher exposure levels. Ultrastructural analysis further revealed membrane deformation, pore formation, and cellular collapse, supporting severe fungal cell damage following treatment. In mammalian L929 fibroblasts, GG-Cys-Quer maintained >85% cell viability at MFC-level exposure, indicating preliminary in vitro cytocompatibility. Overall, these findings demonstrate that GG-Cys-Quer is a structurally characterized guar gum-quercetin conjugate with strong in vitro antifungal activity against C. auris and a mechanism involving oxidative stress, mitochondrial dysfunction, and apoptosis-associated fungal cell death. Further side-by-side studies with free quercetin, linker controls, guar gum controls, and in vivo models are required to define the specific contribution of conjugation and assess translational potential."

These infections often lead to high mortality because biofilms make the fungi more resistant to antifungal drugs and harder for the immune system to clear. Pathogens such as Candida auris, Candida albicans, and Aspergillus fumigatus are particularly problematic, as they are known to develop multidrug resistance and cause persistent infections in critically ill patients. These biofilms often show a much higher tolerance to standard antifungal drugs and can escape the host body's immune defenses. This makes the infections they cause more persistent and very difficult to treat in clinical practice. Antifungal peptides (AFPs), whether derived from natural host-defense molecules or designed through rational engineering, are emerging as promising options for tackling fungal biofilms. They act through several mechanisms, such as disrupting the fungal cell membrane, blocking early adhesion and morphogenesis, and weakening the extracellular matrix. Importantly, they may also work in synergy with existing antifungal drugs, making treatment more effective. Recent progress in peptide engineering and delivery methods, such as nanocarriers and hydrogel-based systems has enhanced the stability, selectivity, and ability of peptides to target fungal biofilms in experimental models. At the same time, there are important challenges that remain, including their tendency to break down due to proteolytic enzymes, possible cytotoxic effects, difficulties in large scale manufacturing, and regulatory hurdles linked to peptide-based therapies. Overall, AFPs represent a promising and fast developing area of research, but their use in clinical practice is limited. More studies are needed to confirm their safety, effectiveness and practical feasibility for managing biofilm-associated fungal infections."

To analyse the molecular epidemiology and resistance mechanisms of 33 clinical isolates in Shanghai and propose an integrated infection control strategy tailored to metropolitan healthcare settings. Isolates from 19 patients were identified via MALDI-TOF MS and sequencing. Antifungal susceptibility and biofilm formation were assessed. Environmental contamination was evaluated using PCR. Whole-genome sequencing (WGS) was employed to identify resistance mutations and perform phylogenetic analysis. All 33 isolates were fluconazole-resistant. Resistance to amphotericin B and echinocandins was observed in 9 and 4 isolates, respectively. All echinocandin-resistant strains harboured the Fks1-S639F mutation. Phylogenetic analysis revealed that Clade III (South African clade) was the dominant lineage. Colonisation was concentrated in the urinary tract and inguinal regions, while bedside tables were identified as key environmental reservoirs. All strains exhibited strong biofilm-forming capacity. ICU patients serve as primary reservoirs, with transmission driven by interregional movement. The distinct colonisation patterns and environmental hotspots provide specific targets for screening.

We analyze the composition, architecture, and dynamics of these structures, showing that they constitute a specific adaptation of the phagocytic actin network. The disruption of phagocytic podosomes is associated with reduced internalization of C. auris and delayed phagosomal maturation. Our data provide detailed insights into cytoskeletal rearrangements upon internalization of Candida by immune cells while also demonstrating that the actin network within phagocytic cups is not necessarily uniform and continuous. At the same time, we identify C. auris as a pathophysiologically relevant target whose internalization involves the formation of phagocytic podosomes."

In recent years, these pathogens have increasingly been reported beyond traditional hospital settings, including neonatal intensive care units, long-term care facilities, oncology wards, and post-pandemic critical care environments. International surveillance bodies, including the Centers for Disease Control and Prevention (CDC), European Centre for Disease Prevention and Control (ECDC), World Health Organization (WHO), and regional monitoring networks, have documented escalating antifungal resistance, complex outbreak dynamics, and persistent gaps in infection control implementation. C. auris has emerged as a major etiological agent of healthcare-associated outbreaks, particularly in intensive care and neonatal units. Surveillance data indicate that a high proportion of C. auris isolates exhibit resistance to azoles, often exceeding 80% in some regions, while echinocandin resistance remains variable. Resistance patterns have evolved from predominantly azole resistance to broader multidrug-resistant phenotypes, including treatment-emergent echinocandin resistance. Six genetically distinct clades (I-VI) have been identified, with Clades I, III, and IV associated with large-scale outbreaks, whereas available data suggests that Clades II, V, and VI are more geographically restricted, although evidence for the recently described clades remains limited. C. glabrata is increasingly recognized as a major cause of invasive candidiasis, with rising resistance reported across multiple regions. While reduced azole susceptibility was historically predominant, emerging evidence highlights rising dual azole-echinocandin resistance, adaptive microevolution during antifungal therapy, and biofilm-associated tolerance mechanisms. Despite these advances, significant gaps persist in global resistance surveillance and in the mechanistic understanding of virulence and antifungal adaptation. Current mitigation strategies include antifungal stewardship programs, expanded resistance testing, and strengthened surveillance systems. Advances in rapid diagnostic technologies such as matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry, polymerase chain reaction (PCR)-based assays, and genomic surveillance have improved pathogen identification and outbreak detection, although accessibility remains limited in resource-constrained settings. This review examines emerging epidemiological, genomic, and antifungal resistance trends in C. auris and C. glabrata and highlights key priorities for improving diagnosis, surveillance, stewardship, and management of multidrug-resistant Candida infections."

The prevalence of fungal infections has significantly increased on a global scale, adversely impacting human health. Candida species remain among the most prevalent and widely spread opportunistic fungi, with Candida auris emerging as a notorious hospital-acquired pathogen. This fungal pathogen causes nosocomial bloodstream infections (BSI), coupled with a high in-hospital death rate and significant multidrug-resistance (MDR). Standard quaternary ammonium compounds (Quats), are often ineffective, requiring the use of Environmental Protection Agency (EPA)-registered hospital-grade disinfectants. Routine laboratory procedures often fail to efficiently identify the fungi, making it difficult to predict the infection\u2019s true severity. Hence, molecular-based methods are now considered the gold standard for rapid identification. Despite the availability of approved drugs, their efficacy is questionable due to the emerging drug resistance within the fungal population. The organism appears to acquire drug resistance quickly. While echinocandins remain first-line therapy, the emergence of echinocandin-or pan-resistant cases indicates that treating pan-resistant strains would be particularly tricky, if not unfeasible. This underscores the urgent need for enhanced infection control, improved point-of-care diagnostics, and the development of novel therapeutic strategies.

Pathogenic mechanisms include biofilm formation, metabolic adaptation to skin, cell wall remodeling, and unique immune evasion strategies, necessitating integrated molecular surveillance and novel therapeutic targeting.\n\n### [INTRODUCTION & JUSTIFICATION]\n*Candida auris* has emerged as a global public health crisis, defined by its rapid nosocomial transmission and multidrug-resistant profile. The organism demonstrates high genomic plasticity across six recognized clades. Adaptation to host environments, particularly the skin, is facilitated by a robust metabolic profile capable of utilizing scarce nutrients in skin-like conditions. Resilience against chemical decontamination and antifungal therapy is multi-factorial, involving efflux pump upregulation (CDR1, MDR1), mutations in target genes like *ERG11* and *FKS1*, and adaptive remodeling of the extracellular matrix. Host immunity is countered by unique cell wall architectures and aggregative growth forms, necessitating a One Health surveillance strategy.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   *Candida auris* colonization shows a distinct predilection for the groin and axillary regions compared to other *Candida* species.\n*   Loss-of-function mutations in the *WOR2* locus are significantly correlated with enhanced biofilm formation capabilities.\n*   *Candida auris* displays unexpected environmental reservoirs, including wastewater and coastal wetlands, suggesting a sapronotic ecology.\n*   While echinocandin resistance is often associated with fitness costs in other fungi, *Candida auris* maintains virulence even after developing resistance mutations.\n*   \"Phagocytic podosomes\" represent a novel actin-rich mechanism utilized by human macrophages for the uptake of *Candida auris*.\n*   Standard diagnostic platforms (VITEK 2, BD Phoenix) frequently suffer from blind spots, resulting in misidentification as *Candida haemulonii* or *Candida famata*.\n*   Environmental disinfectant failure against biofilms is not primarily clade-dependent but driven by formulation and contact time.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Baicalein (BE), a major bioactive constituent of Scutellaria baicalensis Georgi, exhibits notable antifungal potential, yet its specific molecular mechanisms against C. auris remain poorly elucidated. In this study, we determined the antifungal activity of BE against multiple C. auris isolates, assessed its effects on fungal growth, virulence attributes, adhesion, and biofilm development, validated its in vivo protective efficacy in a Galleria mellonella infection model, and explored the underlying mechanisms via transcriptomic sequencing. BE exerted potent and consistent antifungal activity against all tested strains, with a minimum inhibitory concentration of 1 \u03bcg/mL, minimum fungicidal concentrations of 4-8 \u03bcg/mL, and a sessile minimum inhibitory concentration of 32 \u03bcg/mL. It time- and concentration-dependently suppressed fungal growth, virulence factor expression, adhesion to biological and non-biological surfaces, and biofilm formation, while conferring significant in vivo protection against C. auris infection. Transcriptomic analysis identified 11 adhesion- and biofilm-associated target genes, among which SCF1 and ALS1 served as pivotal regulators. Collectively, BE exerts robust anti-C. auris effects by modulating key target gene expression to interfere with multiple virulence-related processes, providing experimental support for its development as a novel antifungal agent for C. auris infection treatment.IMPORTANCEThe emerging multidrug-resistant fungal pathogen Candida auris has become a critical global public health concern. Its pronounced nosocomial transmissibility, high infection-associated mortality, and extensive cross-resistance to mainstream antifungal agents have created substantial unmet needs in clinical treatment and nosocomial infection control. In this study, we systematically validated the in vitro and in vivo antifungal activity of baicalein against C. auris and elucidated the molecular mechanism underlying its modulation of virulence-related genes. Our findings provide a pivotal experimental basis for the development of novel antifungal therapeutics targeting C. auris infections.\n\nID: 42548818\nTitle: In vitro exposure to the agricultural triazole tebuconazole selects for fluconazole cross-resistance and echinocandin tolerance in Candidozyma auris.\nAbstract: The agricultural triazole fungicide tebuconazole (TCZ) has been implicated in the emergence of azole resistance in human fungal pathogens, but its direct role in selecting resistance and tolerance in Candidozyma auris remains unclear. Here, we investigated whether laboratory exposure of a clade III clinical C. auris isolate to TCZ could induce cross-resistance to clinical antifungals. Among 17 agrochemicals tested, only TCZ exhibited intrinsic antifungal activity. Brief (48 h) exposure to sub-MIC TCZ (1 \u03bcg/mL) selected variants (6.9% frequency) with cross-resistance to TCZ and fluconazole, but full susceptibility to caspofungin. Exposure to supra-MIC TCZ (8-32 \u03bcg/mL) produced three phenotypic classes: Class 2 (TCZ-R, fluconazole-R) and Class 3 (TCZ-R, fluconazole-R, plus tolerance to caspofungin and micafungin). The frequency of Class 3 increased dose-dependently from 23% to 50% as TCZ concentration rose. RNA-Seq revealed that both classes overexpressed MDR1, TAC1b, UPC2 and FKS1, but Class 2 showed broad ergosterol pathway upregulation, whereas Class 3 exhibited restricted ergosterol activation but downregulation of the sole chitinase gene CHT1 (5.17-fold), a known mechanism of echinocandin tolerance. Unlike the CRS-MIS phenomenon in Candida glabrata, our Class 3 adaptors displayed equal tolerance to both caspofungin and micafungin. Collectively, these findings demonstrate that, in a clade III clinical isolate of C. auris under the tested laboratory conditions, laboratory exposure to an agricultural triazole can rapidly select for clinically relevant azole cross-resistance and echinocandin tolerance in C. auris, suggesting that environmental fungicide use may inadvertently compromise the efficacy of last-line antifungals.\n\nID: 42527656\nTitle: The urgent and challenging superbug fungus Candidozyma auris (formerly Candida auris): a comprehensive review.\nAbstract: Based on recent literature, this review critically summarises current information on Candidozyma auris (formerly known as Candida auris) infections to identify factors contributing to their emergence and persistence in healthcare settings. Specifically, it seeks to identify major gaps and challenges in Candidozyma auris (C. auris) classification, diagnostic methods, virulence traits, antifungal therapy, and infection prevention, thereby providing a consolidated evidence base to support improved clinical management, surveillance, and future research. Recent advances have enabled rapid, accurate identification of C. auris using updated MALDI-TOF MS databases and real-time PCR assays. Novel antifungal agents and combination therapies offer potential options against resistant and biofilm-forming C. auris, while recent studies of aggregation, biofilm formation and adhesion, and phenotypic switching have provided new insights into its virulence and persistence in healthcare settings. C. auris exhibits many virulence traits that influence the severity of its infections. Identifying C. auris using conventional microbiological and culture-based methods can be challenging, often leading to delayed diagnoses and inappropriate treatment\u00a0of infections. Its resistance to commonly used antifungal drugs, including azoles, polyenes and echinocandins, further complicates infection control and treatment strategies. C. auris strains are classified into six distinct clades: South Asia, East Asia, South Africa, South America, Iran and Singapore. Each clade exhibits unique genetic characteristics and varying levels of drug resistance. The emergence of C. auris underscores the high priority and urgent need for research, the development of practical molecular-based diagnostic tools, novel antifungal therapies, and robust infection control measures to combat this growing threat.\n\nID: 42515081\nTitle: Phosphoproteomics of WHO-Priority Fungal Pathogens: Conserved Signaling Architecture, Pathogen-Specific Outputs, and Therapeutic Vulnerabilities.\nAbstract: Protein phosphorylation is a central post-translational modification. In pathogenic fungi, it dynamically governs morphogenesis, stress adaptation, and antifungal drug resistance. Using high-resolution mass spectrometry-based phosphoproteomics, researchers have systematically mapped phosphorylation dynamics in WHO-priority pathogens-Candida albicans, Aspergillus fumigatus, Cryptococcus neoformans, and the multidrug-resistant Candidozyma auris (formerly Candida auris). These studies reveal that thousands of phosphorylation events are coordinately reprogrammed in response to antifungal drug exposure, host-derived oxidative stress, and temperature shifts. Integration of available datasets suggests a \"conserved-core/divergent-output\" organization. Shared kinase hubs like cAMP-PKA, HOG-MAPK and calcineurin are broadly conserved across species. Downstream substrate networks, however, have diverged, producing distinct virulence outputs in each pathogen. Notably, C. auris remains completely uncharacterized at the phosphoproteomic level. This review provides a comprehensive synthesis of the phosphoproteomic landscape across these pathogens, and discusses how phosphoproteomic data are guiding the rational prioritization of kinases and phosphatases as next-generation antifungal drug targets-with direct implications for clinical surveillance and public health.\n\nID: 42505655\nTitle: Field Evaluation of the ClaID PCR System Reveals Predominance of Clade I-Associated Molecular Profiles Among Clinical Candida auris Isolates Recovered in \u0130stanbul, T\u00fcrkiye.\nAbstract: Background:Candida auris has emerged globally as a multidrug-resistant fungal pathogen responsible for healthcare-associated outbreaks and invasive infections. Whole-genome sequencing studies have demonstrated the existence of genetically distinct clades that differ in geographical distribution, antifungal resistance patterns, virulence traits, and outbreak potential. Objectives: This study aimed to evaluate the performance of the ClaID clade identification PCR system among clinical Candida auris isolates collected in \u0130stanbul, T\u00fcrkiye, and to investigate the clade-associated molecular profiles of circulating isolates. Methods: Forty-four clinical C. auris isolates were analysed using the auris universal sequence (AUS) assay and clade-specific sequence assays (CSS1-CSS5). PCR amplification results were interpreted according to the ClaID framework. Results: AUS amplification was detected in 41/44 isolates (93.2%). CSS1 amplification was observed in 39/44 isolates (88.6%), indicating a predominance of Clade I-associated molecular profiles within this regional \u0130stanbul isolate collection. No amplification was detected using CSS2, CSS3, CSS4, or CSS5 assays. Three isolates were AUS-negative and five isolates did not yield CSS1 amplification despite repeated testing. Conclusions: The findings suggest that the majority of analyzed clinical isolates from \u0130stanbul exhibited Clade I-associated molecular profiles rather than definitive WGS-confirmed clade assignments. This study provides one of the first field evaluations of the ClaID system in a Turkish clinical isolate collection and contributes regional molecular epidemiological data regarding PCR-based clade-associated profiles of C. auris in T\u00fcrkiye.\n\nID: 42499548\nTitle: Candida auris: a review of global epidemiology, multidrug resistance, and infection control in healthcare-associated outbreaks.\nAbstract: Candida auris, designated a critical-priority fungal pathogen by the World Health Organization, poses a growing threat to healthcare systems worldwide. Analysis of 80 peer-reviewed studies reveals five principal findings: (1) C. auris exhibits clade-dependent geographic distribution and resistance profiles-Clade I (South Asia) and Clade III show fluconazole resistance exceeding 90%, whereas Clade IV exhibits 44% resistance; echinocandin resistance varies significantly by clade and no resistance was detected in certain clades; amphotericin B resistance varies from no detected resistance to 46% depending on clade; and pan-resistant strains have emerged; (2) biofilm-associated C. auris cells (sessile cells) exhibit MBECs 2- to 4,119-fold higher than planktonic MICs, representing a major driver of persistent colonization; (3) novel antifungal agents, including ibrexafungerp, manogepix (the active moiety of fosmanogepix), and rezafungin, demonstrate promising in vitro activity against C. auris, with manogepix showing the highest overall antibiofilm activity (geometric mean MBEC of 5.9 \u03bcg/mL) and ibrexafungerp demonstrating superior activity against Clade IV biofilms; (4) a tiered infection prevention and control (IPC) framework-integrating universal screening, contact precautions, and environmental decontamination-has been associated with reduced transmission rates in outbreak settings; and (5) climate change and global warming may have contributed to the emergence of C. auris through thermal adaptation of environmental fungal species. These findings indicate that effective mitigation of the C. auris threat requires integrated surveillance, susceptibility-guided therapy accounting for both planktonic and biofilm activity, and resilient healthcare systems adapted to the clade-specific epidemiology of this pathogen.\n\nID: 42406015\nTitle: The Emerging Global Threat of Candida auris: A Call for Enhanced Public Health Policy and Regional Coordination.\nAbstract: Antimicrobial resistance represents a paramount challenge to global public health in the 21st century. The multidrug-resistant fungal pathogen Candida auris poses a critical and escalating threat to global public health. Characterized by rapid nosocomial transmission, persistent environmental contamination, and resistance to multiple antifungal classes, C. auris challenges healthcare systems worldwide. Its independent emergence across distinct geographic clades and exponential rise in cases, exacerbated by the COVID-19 pandemic, underscore the urgent need for robust, coordinated response. This review synthesizes the current knowledge on C. auris with a focus on its implications for public health policy, particularly in the European and Balkan healthcare settings, where surveillance gaps and cross-border transmission risks remain pronounced. We analyze the key drivers of spread, including diagnostic misidentification, extensive antifungal resistance, and lapses in infection control, and evaluate the strain on surveillance and hospital preparedness. Effective mitigation is fundamentally dependent on implementing comprehensive, multi-faceted infection prevention and control strategies, guided by antifungal stewardship and rapid diagnostics. We conclude that addressing the C. auris threat requires an urgent, coordinated international and regional response focused on strengthening surveillance networks, standardizing diagnostic and infection prevention and control protocols, and fostering data sharing across borders to contain this resilient pathogen.\n\nID: 42405804\nTitle: Morphotype-specific susceptibility to Neosartorya (Aspergillus) fischeri antifungal protein 2 is associated with an anabolic transcriptional signature in Candida.\nAbstract: The emergence of drug-resistant Candida species has created a demand for global antifungal strategies that extend beyond classical growth inhibition to target unknown vulnerabilities of fungal pathogens. In this study, we demonstrated that the Neosartorya (Aspergillus) fischeri antifungal protein NFAP2 selectively targets early morphogenetic states of Candida albicans and Candidozyma auris, revealing a transient window of susceptibility during filament and pseudohypha formation. Integrated transcriptomic and in vivo analyses indicate that these developmental states may represent context-dependent entry points for NFAP2 activity. In C. albicans, transcriptomic and network analyses indicate the presence of an anabolic, translation-associated gene expression signature, accompanied by suppression of stress-protective pathways, which is associated with increased susceptibility of emerging hyphae to NFAP2 but does not establish a direct causal mechanism. In C. auris, increased susceptibility of pseudohyphal cells occurred without overt transcriptional remodeling, consistent with the characteristically muted gene expression responses of this species, suggesting that NFAP2 sensitivity is governed primarily by biophysical and post-transcriptional mechanisms rather than transcriptional reprogramming. Importantly, morphotype-specific vulnerabilities observed in vitro were reflected in distinct in vivo outcomes in Galleria mellonella, as NFAP2 was well tolerated and provided a moderate, transient survival benefit in pseudohyphal C. auris infections, but not in filamentous C. albicans, where a worsened outcome was observed, consistent with species- and morphotype-dependent activity. Taken together, these results suggest that early morphogenetic states of Candida are stress-sensitive phenotypes associated with increased susceptibility to NFAP2. This work provides a proof-of-concept framework for future investigation of morphotype-associated antifungal vulnerability to peptide-based antifungal strategies.IMPORTANCEDrug-resistant Candida species represent an escalating global health threat; however, most antifungal strategies continue to target fungal growth rather than intrinsic biological vulnerabilities. In this study, we identified early morphogenetic transitions as a shared window of increased susceptibility in both Candida albicans and the highly drug-resistant pathogen Candidozyma (formerly Candida) auris. By integrating transcriptomic profiling with in vivo infection models, we found that NFAP2 exhibits antifungal activity that is influenced by these transient developmental states in a context-dependent manner while remaining well tolerated by the host. We further demonstrated that morphotype-specific stress responses are associated with the divergent sensitivities of C. albicans and C. auris to NFAP2. These results support the concept that fungal morphogenesis may represent a therapeutically actionable process and provide a framework for designing antifungal strategies that target developmental states rather than growth. This strategy may open new opportunities for improving protein- and peptide-based therapies, as well as combination therapies against difficult-to-treat fungal pathogens.\n\nID: 42396049\nTitle: C. auris in Wastewater: Current Evidence, Risks, One Health Implications, and Knowledge Gaps.\nAbstract: Candidozyma aurisauris (formerly Candida auris) is an emerging, multidrug-resistant fungal pathogen that is difficult to identify and has become an increasing challenge for global public health. In recent years, its detection in wastewater has raised concerns regarding the potential environmental dimensions of its dissemination and the associated public health implications. This study examines the current evidence on the occurrence of C. auris in wastewater, with an emphasis on the concentration, isolation, and identification methodologies employed in recent investigations. Framed within a One Health perspective, the analysis discusses potential pathways of environmental dissemination through wastewater effluents and biosolids, particularly in the context of the expanding reuse of treated wastewater and the land application of sewage sludge. The review also highlights existing regulatory gaps, including the absence of specific guidelines addressing pathogenic fungi in wastewater treatment plant byproducts as well as the lack of standardization in reported data, which hinders more in-depth analyses. Overall, this work identifies important knowledge gaps and emphasizes the need for further studies and interdisciplinary surveillance strategies to better understand the environmental circulation of C. auris. Additionally, a conceptual workflow is proposed to advance the standardization of analytical approaches and data reporting, contributing to strengthening public health, environmental protection, and sanitary policies.\n\nID: 42370646\nTitle: HAC1 contributes to stress adaptation and virulence in the emerging fungal pathogen Candida auris.\nAbstract: Candida auris (Candidozyma auris) is an emerging multidrug-resistant fungal pathogen that poses a significant global health threat. However, the molecular mechanisms underlying its virulence remain incompletely understood. In this study, we performed in vivo transcriptome analysis using an immunosuppressed mouse gastrointestinal infection model to identify genes associated with host adaptation and virulence during infection. By comparing fungal transcriptomes obtained from colonization and dissemination sites with those from\u00a0in vitro cultures, we identified genes that were consistently upregulated during infection. Among these genes, the unfolded protein response regulator HAC1 was selected as a candidate virulence-associated gene for further analysis. Reverse transcription PCR and sequencing analyses revealed that\u00a0HAC1 mRNA in C. auris undergoes an unconventional splicing event of 287 bp that is enhanced under endoplasmic reticulum stress conditions. The excised region spans the annotated open reading frame boundary, suggesting that the translated region of\u00a0HAC1 may require re-evaluation. Notably, a proportion of HAC1 transcripts appeared to be spliced even under non-stress conditions, indicating a detectable basal level of the unfolded protein response. Differences in splicing dynamics were also observed among clade strains. Functional analyses demonstrated that deletion of\u00a0HAC1 increased sensitivity to endoplasmic reticulum stress. The HAC1 deletion mutant also exhibited reduced virulence in both Galleria mellonella and immunosuppressed mouse infection models, as evidenced by delayed host mortality and decreased fungal burdens, respectively. These findings indicate that HAC1 contributes to endoplasmic reticulum stress adaptation and survival in the host environment and identify\u00a0HAC1 as a virulence-associated gene in C. auris. Candida auris is an emerging multidrug-resistant fungal pathogen. Using in vivo transcriptome analysis, we identified HAC1 as a regulator of endoplasmic reticulum stress adaptation and virulence in infection models. This study provides new insight into stress-response pathways in C. auris virulence.\n\nID: 42369549\nTitle: A targeted drug-repurposing strategy identifies Tavaborole (Kerydin) as a potent fungistatic agent against Candida auris.\nAbstract: Candida auris is an emerging multidrug-resistant fungal pathogen posing a major global health threat. In this study, we employed a targeted drug-repurposing strategy to identify novel indications for existing FDA-approved compounds against C. auris, leading to the identification of Tavaborole as a potent fungistatic agent. Tavaborole displayed robust activity across all five tested clades of C. auris, as well as against Candida albicans and Candida glabrata. To investigate drug resistance mechanisms of C. auris, we applied quantitative proteomics analyses following exposure to Tavaborole and Amphotericin B (AmB), complemented by electron microscopy. Proteomic profiling revealed that C. auris mounts distinct but overlapping adaptive responses to antifungal stress, involving stress response pathways, metabolic reprogramming and amino acid biosynthesis. While Tavaborole primarily induced targeted stress adaptation, AmB triggered a broader, multi-pronged resistance response including oxidative stress mitigation, osmolyte production and metabolic remodeling. Shared alterations in glycogen metabolism and amino acid biosynthesis suggest conserved antifungal adaptation mechanisms. Altogether, this study highlights Tavaborole as a promising antifungal candidate against C. auris, sheds novel insights into drug resistance mechanisms employed by the pathogen and delivers a drug-repurposing procedure highly customizable to target other microorganisms.\n\nID: 42346858\nTitle: From Species Identification to Empirical Therapy: A Machine Learning and Rule-Based Decision Support Framework for Antifungal Resistance Prediction in ICU Candida Infections.\nAbstract: Objectives: When a Candida species is identified in an ICU patient, susceptibility results are typically available in 24-72 h. In this study, we built a machine learning model using four variables available at identification to estimate resistance probability in real time. Methods: We analysed 747 fungal isolates from 725 ICU patients (January 2021-March 2026). We trained and compared a Random Forest and a Logistic Regression model, evaluating both with temporal cross-validation, permutation feature importance, three-category (S/I/R) prediction, and calibration analysis. Results: Multidrug resistance doubled from 24.5% (2021) to 51.1% (2025), and Candida auris grew eight-fold in three years. Random Forest reached AUC 0.885 on the held-out test set and 0.848 on prospective 2024-2025 data (Brier score 0.093). Species identity and drug choice together explained 87% of predictive signal. Local C. albicans fluconazole resistance (~16%) far exceeded the ECMM European figure of 0%, and C. krusei was four times more prevalent than the continental average. Conclusions: A four-variable model may provide calibrated resistance estimates during the critical gap before susceptibility results return, though performance reflects predominantly deterministic species-drug patterns rather than complex learned biology. Overall performance was comparable to a rule-based lookup table, confirming that the majority of predictive signal derives from established species-drug susceptibility patterns. Meaningful added value is limited to temporal trend tracking and improved prediction where resistance is acquired rather than intrinsic (C. albicans, C. tropicalis hard-subset AUC 0.929 vs. rule-based 0.899). The model complements a local antifungal testing; it does not replace one.\n\nID: 42310987\nTitle: Rectal versus groin screening for multidrug-resistant organisms: pathogen-specific diagnostic yield in a tertiary-care hospital.\nAbstract: To evaluate the pathogen-specific diagnostic yield of rectal and groin screening sites in a hospital-based multidrug-resistant organism (MDRO) surveillance program. Prospective observational surveillance study. Tertiary academic hospital in Northern Greece. Hospitalized patients undergoing active MDRO screening based on predefined infection prevention and control criteria. A pathogen-focused analysis was conducted using data from a prospective MDRO surveillance program between October 2024 and January 2025. Screening swabs were obtained from the rectum and groin. Target organisms included multidrug-resistant (MDR) Klebsiella pneumoniae, Pseudomonas aeruginosa, vancomycin-resistant enterococci (VRE), Candida auris, and Acinetobacter spp. Pathogen-specific detection yields were calculated for each anatomical site. Among 1,206 screening swabs, 308 (25.5%) were positive for at least one MDRO. Rectal swabs detected 95.8% of Klebsiella pneumoniae (K. pneumoniae) (92/96), 100% of VRE (59/59), and 66.7% of Pseudomonas aeruginosa (46/69). In contrast, 88.9% of Candida auris cases (24/27) were identified exclusively from groin swabs. Reliance on rectal screening alone would have missed nearly 90% of Candida auris carriers, whereas groin-only screening would have failed to detect most K. pneumoniae and all VRE carriers. Anatomical site selection critically influences MDRO surveillance sensitivity. Rectal screening is optimal for MDROs colonizing the gastrointestinal tract, whereas groin sampling is essential for detecting Candida auris. Pathogen-targeted, site-specific surveillance strategies may substantially improve detection efficiency and optimize infection prevention efforts in high-prevalence hospital settings.\n\nID: 42298784\nTitle: Phenotypic switch Candidozyma auris (Candida auris) modulates biofilm formation and virulence genes SAP5 and ALS5 in mono- and co-culture environments with Staphylococcus aureus.\nAbstract: Candidozyma auris (formerly Candida auris) (C. auris), an emerging multidrug-resistant fungal pathogen, forms biofilms as a virulence factor. This study aimed to determine the effect of phenotypic switch on C. auris biofilm formation and virulence gene expression in mono- and co-culture with Staphylococcus aureus. Phenotypic switching was induced by prolonged incubation, and biofilms were developed in RPMI-1640, YEPD, SDB, and BHIYE. The biofilm biomass and total cell count were measured. SAP5 and ALS5 gene expression was quantified using qPCR. The 4th switched generation mono-culture biofilm in BHIYE produced the highest biomass (3.34\u2009\u00b1\u20090.08) and total cell count (5.66\u2009\u00b1\u20090.03 log10 cells mL-1). In addition, SAP5 and ALS5 expression peaked in the 2nd switched generation mono-culture by 10.43\u2009\u00b1\u20090.44-fold and 4.764\u2009\u00b1\u20090.01-fold, respectively. Co-culture biofilms exhibited significantly higher ALS5 expression in selected switched generations compared to unswitched C. auris (p\u2009<\u20090.05). In conclusion, phenotypic switching enhanced biofilm formation and modulated the expression of SAP5 and ALS5 in C. auris.\n\nID: 42295827\nTitle: A simplified MALDI-TOF MS method for rapid fluconazole susceptibility testing in Candida species.\nAbstract: Introduction. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) is widely used for rapid micro-organism identification and has recently been explored for antifungal susceptibility testing (AFST).Hypothesis. Although MALDI-TOF MS has emerged as a promising tool for AFST, simplified and clinically applicable strategies for rapid fluconazole (FLZ) susceptibility detection in Candida spp. remain insufficiently validated. We hypothesized that a streamlined AFST-MS approach would demonstrate good categorical agreement (CA) with the European Committee on Antimicrobial Susceptibility Testing (EUCAST) reference method while significantly reducing turnaround time.Aim. To establish a simplified MALDI-TOF MS-based AFST approach for detecting FLZ resistance in Candida species.Methodology. Fifty-one clinical isolates and reference strains were incubated for 3 h in the presence of FLZ at two concentrations (32 and 4 \u00b5g ml-1) and in drug-free controls. Spectral profiles were compared with the EUCAST reference method.Results. Overall CA between AFST-MS and EUCAST was 85.2% (\u03ba=0.7306). Species-specific accuracy was 100% for Candida auris, Pichia kudriavzevii (formerly Candida krusei), Candida tropicalis and Candida parapsilosis; 92.9% for Candida albicans and 40% for Nakaseomyces glabrata (formerly Candida glabrata); however, these estimates should be interpreted cautiously given the limited number of isolates per species. All discrepancies were minor errors, with no major or very major errors observed. The method reduced analysis time from 24 to 3 h and enabled presumptive FLZ susceptibility detection with good overall agreement with the reference methodConclusion. These findings support the potential of MALDI-TOF MS as a rapid adjunct tool for antifungal susceptibility assessment and may contribute to earlier therapeutic decision-making.\n\nID: 42283785\nTitle: Insights on molecular drivers of phenotypic plasticity in Candidozyma auris.\nAbstract: Candidozyma auris (or Candida auris) is the first fungal species declared as a global health threat by the U.S. Center for Disease Control and Prevention (CDC). Its high environmental persistence, immune evasion, phenotypic heterogeneity, and multidrug resistance are major contributors to its high mortality rate. Under diverse environmental conditions, C. auris exhibits marked phenotypic plasticity, switching from non-aggregative to aggregative form and, in some contexts, pseudohyphal-like morphotypes. However, the significance of this heterogeneity in pathogenesis and drug tolerance remains poorly understood. This review provides a comprehensive overview of how external cues influence C. auris morphotypes, with particular emphasis on aggregation. It further highlights the role of adhesion-associated genes (ALS4112 and SCF1) in mediating cell aggregation and examines their evolutionary trajectories across Candida species and among distinct C. auris clades. In addition, we discuss emerging molecular mechanisms that may underlie differential morphotypes and their links to virulence and antifungal tolerance. Evidence suggests that mannan-mediated masking of pathogen-associated molecular patterns (PAMPs) in the aggregative phenotype may contribute to persistence and reduced virulence in the host. Overall, C. auris can remodel its cell wall and elicit distinct host immune responses based on its form, opening avenues for novel therapeutic strategies which further require deeper experimental validation.\n\nID: 42265601\nTitle: Clinical characteristics, healthcare-associated exposures, and antifungal susceptibility patterns of Candida auris colonization and invasive infections: a retrospective observational study at a single center in Turkey.\nAbstract: Candida auris (Candidozyma auris) differs from other yeast species by its ability to persist for prolonged periods on environmental surfaces and human skin. This feature facilitates person-to-person transmission and contributes to healthcare-associated infections and outbreaks. In this study, both invasive C. auris infections and colonization were evaluated together. We aimed to compare clinical characteristics and healthcare-associated exposures between invasive and colonized cases and to assess antifungal susceptibility patterns in invasive infections. A total of 79 patients with C. auris isolation between December 2022 and April 2025 were retrospectively analyzed. Species identification was confirmed using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. Patients with C. auris isolated from invasive specimens, such as blood or tissue, were classified as having invasive infection, whereas those with isolation from non-invasive specimens such as axilla/groin swabs, nasal swabs, urine, catheters, and sputum, without concurrent invasive positivity, were classified as colonized. Patients with both screening and invasive positivity were included in the invasive infection group for comparative analyses. Antifungal susceptibility to amphotericin B, fluconazole, micafungin, and anidulafungin was determined on invasive isolates using the Sensititre YeastOne colorimetric microdilution method. Interpretation of results was based on the tentative breakpoints defined by the United States Centers for Disease Control and Prevention and the epidemiological cutoff values established by the European Committee on Antimicrobial Susceptibility Testing. Demographic characteristics, clinical variables, and healthcare-associated exposures were compared between the invasive infection and colonization groups. A total of 91 C. auris isolates from 79 patients were evaluated. Invasive infection was detected in 41 patients (52%) and colonization in 38 patients (48%). Most cases were observed in intensive care and palliative care units. Among screening sites, axilla/groin swabs showed the highest positivity rate. Central venous catheter use, intubation, surgical history, and decubitus ulcer were numerically more frequent among invasive cases; however, none of these differences reached statistical significance. Echinocandin resistance developed in two patients during follow-up. The median age was significantly higher in the invasive group than in the colonized group (74 vs. 64.5 years; p\u2009=\u20090.002). Accurate identification of C. auris and continuous antifungal susceptibility surveillance are essential for infection control. Older age was the only variable significantly associated with invasive infection, while other clinical and healthcare-associated exposures were common in both groups but did not differ significantly. All isolates were resistant to fluconazole, and echinocandin resistance emerged in two isolates. Amphotericin B susceptibility findings should be interpreted cautiously, as the use of Sensititre YeastOne without confirmatory reference testing may have overestimated resistance. Larger multicenter studies are needed to better define factors independently associated with invasive infection.\n\nID: 42235503\nTitle: High burden of multidrug-resistant Candidozyma (formerly Candida) auris in a tertiary care haematology unit: Diagnostic pitfalls and identification of high-risk clinical areas.\nAbstract: Candidozyma (formerly Candida) auris is a multidrug-resistant critical priority pathogen, posing significant challenges in high-risk settings. This study was aimed to determine the proportion of C. auris among candidemia, evaluate automated antifungal susceptibility testing (AFST) against Broth Microdilution (BMD), and identify high-risk areas in a haematology unit. A prospective cross-sectional study (September 2024-September 2025) screened 3894 blood cultures in a Kolkata hospital. Isolates were identified via Vitek-2 and MALDI-TOF MS. Vitek 2 AFST results were compared with the gold-standard BMD. Spatial mapping was utilized to identify ward clustering. Excluding paediatric and non-haematology cases, the adult C. auris cohort (n\u00a0=\u00a038) was analysed (mean age 25.8\u00a0\u00b1\u00a011.2 years). All had haematological malignancy and neutropenia, with central venous catheters in 81.6% (n\u00a0=\u00a031). The 30-day crude mortality was 15.8% (n\u00a0=\u00a06). Diagnostically Vitek 2 demonstrated a critical 47.4% Major Error rate for Amphotericin B compared to BMD (P\u00a0< 0.001), significantly overestimating resistance. Spatial mapping identified persistent environmental reservoirs around specific high-traffic beds. Vitek 2 significantly overestimates Amphotericin B resistance, necessitating BMD verification to prevent inappropriate exclusion of polyene therapy. The infection burden in young, neutropenic adult highlights a vulnerable demographic. Persistence case clustering suggests environmental fomite colonization, requiring enhanced diagnostic stewardship and targeted sporicidal decontamination in haematology units. The resistant fungus Candidozyma auris is a severe threat to young leukaemia patients. We found that standard automated lab tests frequently misdiagnose its drug resistance. Manual testing is vital to ensure these vulnerable patients receive the correct, life-saving treatment.\n\nID: 42229743\nTitle: Antifungal peptides for biofilm disruption: Mechanisms, design strategies, and translational outlook.\nAbstract: Invasive fungal infections in intensive care units are a serious concern, especially when they are associated with biofilm formation. These infections often lead to high mortality because biofilms make the fungi more resistant to antifungal drugs and harder for the immune system to clear. Pathogens such as Candida auris, Candida albicans, and Aspergillus fumigatus are particularly problematic, as they are known to develop multidrug resistance and cause persistent infections in critically ill patients. These biofilms often show a much higher tolerance to standard antifungal drugs and can escape the host body's immune defenses. This makes the infections they cause more persistent and very difficult to treat in clinical practice. Antifungal peptides (AFPs), whether derived from natural host-defense molecules or designed through rational engineering, are emerging as promising options for tackling fungal biofilms. They act through several mechanisms, such as disrupting the fungal cell membrane, blocking early adhesion and morphogenesis, and weakening the extracellular matrix. Importantly, they may also work in synergy with existing antifungal drugs, making treatment more effective. Recent progress in peptide engineering and delivery methods, such as nanocarriers and hydrogel-based systems has enhanced the stability, selectivity, and ability of peptides to target fungal biofilms in experimental models. At the same time, there are important challenges that remain, including their tendency to break down due to proteolytic enzymes, possible cytotoxic effects, difficulties in large scale manufacturing, and regulatory hurdles linked to peptide-based therapies. Overall, AFPs represent a promising and fast developing area of research, but their use in clinical practice is limited. More studies are needed to confirm their safety, effectiveness and practical feasibility for managing biofilm-associated fungal infections.\n\nID: 42199049\nTitle: Mechanisms and species-specific patterns of ECM-mediated antifungal resistance in Candida biofilms: a systematic review and exploratory quantitative synthesis.\nAbstract: To synthesize mechanistic evidence on how extracellular matrix (ECM) components of Candida biofilms contribute to antifungal resistance across species and antifungal drug classes. We conducted a PRISMA-guided systematic review with exploratory random-effects quantitative synthesis of peer-reviewed experimental studies evaluating ECM composition, matrix-associated regulatory pathways and antifungal susceptibility in Candida biofilms. Qualitative synthesis mapped ECM components and pathways, while harmonizable semi-quantitative data were summarized as directional modeled estimates. Of 38 full-text records assessed, 33 primary studies were included in the qualitative synthesis and 25 contributed to the exploratory pooled analysis. Preservation or modulation of ECM-associated mechanisms showed a strong modeled directional association with reduced antifungal susceptibility (pooled modeled odds ratio: 4.28, 95% CI: 4.06-4.52). \u03b2-1,3-glucan was the most consistently supported sequestration scaffold, particularly for azoles and polyenes. Mannan-glucan complexes, matrix proteins, extracellular DNA and vesicle-associated lipids provided complementary structural and remodeling functions. Non-albicans Candida species, especially Candida glabrata and Candida auris, more often combined ECM protection with efflux-linked resistance. ECM-mediated resistance in Candida biofilms is multilayered, species-dependent and drug-class specific. These findings support species-aware interpretation of biofilm-associated antifungal resistance and further development of ECM-directed adjunctive strategies.\n\nID: 42185810\nTitle: Comparison of candidemia caused by Candida auris and non-auris Candida spp.: a retrospective cohort study on clinical characteristics, risk factors, and antifungal resistance profiles.\nAbstract: Candida auris has emerged as a significant global health threat due to its resistance to multiple antifungal agents and its prominent role in healthcare-associated infections. This study aims to compare the clinical characteristics, risk factors, antifungal resistance profiles, and mortality rates of candidemia caused by C. auris and non-auris Candida spp. (NACS). This retrospective cohort study was conducted at a tertiary care hospital from 2021 to 2024. Patients aged 18 years and older with positive blood cultures for Candida spp. were included. Demographic data, comorbidities, risk factors, mortality rates, and treatment protocols were analyzed. A total of 1,088 candidemia cases were included in the study (C. auris: 126 cases, NACS: 962 cases). The length of hospital stay was significantly longer in the C. auris group compared to the NACS group (50.98\u2009\u00b1\u200938.79 vs. 33.05\u2009\u00b1\u200925.57 days, p\u2009<\u20090.001). Independent risk factors for C. auris candidemia included longer hospitalization before candidemia (OR 1.01, 95% CI 1.01-1.02, p\u2009<\u20090.001), chronic obstructive pulmonary disease (OR 1.89, 95% CI 1.07-3.31, p\u2009=\u20090.026), prior antifungal use within 30 days (OR 1.92, 95% CI 1.22-3.03, p\u2009=\u20090.005), and ICU admission (OR 2.08, 95% CI 1.10-3.92, p\u2009=\u20090.023). Antifungal resistance rates among C. auris isolates were 96.49% for fluconazole, 72.81% for amphotericin B, and 25.89% for caspofungin. The 30-day mortality rate was lower in the C. auris group (48.4%) compared to the NACS group (60.2%) (p\u2009=\u20090.012). Although crude 30-day mortality was lower in the C. auris group, adjusted analysis showed comparable 30-day mortality between the C. auris and NACS groups. These findings highlight the increasing clinical burden of C. auris and support accurate species identification, local antifungal susceptibility surveillance, and rigorous infection-control measures. Not applicable.\n\nID: 42159584\nTitle: Towards accurate genomic detection of fungal antimicrobial resistance: progress in fungal resistance databases and bioinformatic tools.\nAbstract: Fungal antimicrobial resistance (fAMR) is increasing worldwide and is recognized as a global health priority by the World Health Organization. The emergence of Candidozyma (Candida) auris and other resistant fungal pathogens presents a risk to critically ill patients. Whole-genome sequencing has the potential to improve public health and clinical surveillance for fAMR and could enable more rapid detection. In this review, we discuss the mechanisms of fAMR and the strengths and limitations of the currently available databases and bioinformatic tools for the detection of fAMR from genomic data. We identify current gaps, preferred characteristics of genomic fAMR databases and tools and future directions for development to enable validated fAMR prediction in the public health context.\n\nID: 42119224\nTitle: Interplay between Candida auris and host immunity: Highlighting its unique strategies for resisting host immune responses.\nAbstract: Candida auris, an emerging \"super fungus,\" poses a global threat owing to multidrug resistance, rapid transmission, and high mortality. Distinct from other clinically prevalent fungal pathogens such as Candida species, C. auris employs unique defense mechanisms against the host immune system, including immune evasion and survival strategies. This review summarizes the distinct strategies used by C. auris to resist host immune responses. In particular, C. auris exhibits pronounced genomic and morphological plasticity, which facilitates rapid adaptation to host-derived stressors. Its modified cell wall, characterized by a thicker mannan layer, efficiently masks immunogenic \u03b2-glucan, thereby reducing immunogenicity. Furthermore, multicellular features, including robust biofilms and unique aggregative forms, enhance colonization, transmission, and stress resistance. C. auris also secretes diverse virulence factors and undergoes adaptive metabolic reprogramming under nutrient limitation, promoting more efficient immune evasion and survival within the host. Collectively, these flexible defensive strategies confer enhanced host immune resistance, contributing to its heightened pathogenicity. This review provides novel perspectives on future research directions and potential therapeutic strategies for managing C. auris infections.\n\nID: 42071049\nTitle: National Surveillance of Candidemia in the Czech Republic: Preliminary Results from the 2023 Multicentre Study.\nAbstract: This study aimed to obtain data describing the epidemiology and antifungal susceptibility of yeasts isolated from bloodstream infections (BSI) in the Czech Republic (CR). This study presents data from the first year of a national, long-term surveillance program. All microbiologically confirmed candidemia cases in patients hospitalized at 30 Czech centers in 2023 were evaluated. This study assessed BSI incidence per 100,000 inhabitants, species distribution, and antifungal susceptibilities (EUCAST E.Def 7.4 protocol) of strains.aff Whole-genome sequencing was performed on selected isolates with acquired resistance or non-wild-type phenotypes to determine the molecular mechanisms of resistance. In total, 433 isolates from 408 unique BSI episodes in 398 patients were recorded in 2023. Candida albicans was the most frequent species (40.6%), followed by Candida glabrata (24.5%), Candida parapsilosis (14.5%), and Candida tropicalis (5.5%). In pediatric patients, C. albicans (58.8%) was the most common, followed by C. parapsilosis (17.6%). Candida auris BSI was not detected in 2023. The highest rates of acquired fluconazole resistance were detected in C. parapsilosis (16.9%) and C. glabrata (15.4%). Most fluconazole-resistant (FLC-R) C. parapsilosis isolates carried Y132F mutation in ERG11 gene (14/15; 93.3%). One isolate of C. glabrata was resistant to echinocandins (1.3%), but remained susceptible to azoles, mutations in FKS1 (G14S) and FKS2 (S663P, T926P) were identified. This nationwide survey provides the first comprehensive yeast BSI surveillance data from the Czech Republic, which spans the entire country. CR follows trends observed in developed countries, with a decline in C. albicans and a rise in C. glabrata infections. To our knowledge, this is the first report describing FLC-R C. parapsilosis isolates carrying the Y132F ERG11 mutation in CR. These findings highlight several emerging challenges that reflect global trends: a shifting spectrum of Candida species from C. albicans to non-albicans species, and rising levels of acquired azole resistance. Therefore, continuous national monitoring is essential.\n\nID: 42065710\nTitle: Candida (Candidozyma) auris strains exposed to azole fungicides become less susceptible to manogepix.\nAbstract: Candida auris is a multidrug-resistant fungal pathogen responsible for invasive nosocomial infections with high mortality rates. Recent detection of C. auris in natural environments suggests the existence of an environmental reservoir, prompting investigation into the potential role of azole fungicides used for plant protection in the development of resistance to antifungals used in human medicine. Here, we assessed the impact of azole fungicides on in vitro resistance development in two C. auris strains (B11220 and B11221) through sequential exposure to epoxiconazole, propiconazole, or tebuconazole. Exposure resulted in a rapid and significant increase in fungicide MICs, accompanied by a reduced susceptibility to four azole antifungals (fluconazole, voriconazole, posaconazole, isavuconazole), and to a new antifungal agent, the manogepix. Several strains with elevated MICs exhibited stable phenotypes and were associated with a mutation in the TAC1B gene. One of these strains showed a significant overexpression of the efflux pump CDR1. These findings provide experimental evidence that azole fungicides can drive resistance to azole antifungals and reduce susceptibility to manogepix, underscoring the need for integrated One Health antifungal stewardship strategies to combat C. auris. Candida auris is a yeast that causes infection in humans and has been detected in the environment. We have shown that fungicides used in agriculture can reduce the susceptibility of C. auris to antifungal drugs used in human medicine.\n\nID: 42059109\nTitle: Trends in Antifungal Resistance and Mechanistic Insights Into Azole Resistance in Candida (Candidozyma) auris: A 13-Year Study of a Comprehensive Set of Clinical Isolates From India.\nAbstract: The objective of the study was to elucidate antifungal resistance and associated azole resistance mechanisms in Candida (Candidozyma) auris isolates across India over a period of 13 years (2009-2021). A total of 596 C. auris isolates from 37 healthcare centers were collected. Antifungal susceptibility was performed and ERG11 gene was sequenced for 45 representative isolates. The ERG11 and efflux pump (MDR1 and CDR1) expression under fluconazole drug pressure was assessed by quantitative reverse-transcription polymerase chain reaction (n = 20) along with cell wall ergosterol content estimation. Short tandem repeat (STR) genotyping was done on 235 isolates. The highest number of isolates (50.1%) was recovered from northern India, followed by eastern (27.6%) and southern India (13.6%). The majority of the isolates were recovered from private sector hospitals. A total of 80.0% and 27.9% of isolates were resistant to fluconazole and voriconazole, respectively. A notable increase in resistance to amphotericin B and caspofungin was observed, with 3.2% of isolates being multidrug resistant. In ERG11, Y132F and K143R mutations were present in both fluconazole-susceptible and -resistant isolates; in addition, 50% of fluconazole-susceptible isolates showed elevated ERG11 expression and ergosterol content upon fluconazole treatment. Basal level cell wall ergosterol was higher in fluconazole-susceptible isolates. All isolates belonged to clade I with STR genotyping. Our study demonstrates high levels of antifungal resistance in the largest collection of Indian C. auris clinical isolates reported to date. Besides mutations and gene expressions, other pathways conferring drug resistance, such as stress response, must be studied to further understand the evolution of this pathogen.\n\nID: 42051239\nTitle: Micafungin microevolution in Candida auris reveals resistance development without in vivo fitness compromise.\nAbstract: Candida auris is an emerging multidrug-resistant pathogen with high transmissibility in healthcare settings. Although echinocandin resistance in Candida is typically associated with fitness loss, we found that micafungin-resistant C. auris strains (MICAevo) generated from two distinct source isolates (AR0381 and AR0387) via experimental microevolution retained full virulence. Evolved strains developed stable resistance to multiple echinocandins, while AR0387 (B8441), originating from MICAevo strain, also acquired increased azole tolerance. Whole-genome sequencing revealed clinically relevant mutations in FKS1, as well as changes in genes involved in ergosterol biosynthesis (ERG3), amino acid metabolism, and PKA signaling. Despite in vitro sensitivity to cell wall stressors, resistant strains maintained or even enhanced colonization in a murine systemic infection model. Independently evolved strains showed similar antifungal resistance profiles, and although minor differences of pathogenic potential were noted, no consistent virulence attenuation was observed, indicating the reproducibility of phenotype changes. These findings suggest that C. auris can acquire echinocandin resistance without compromising pathogenicity, supporting its persistence and spread in clinical settings.\n\nID: 42044884\nTitle: Updated Genomic Epidemiologic Description of Candida (Candidozyma) auris, United States.\nAbstract: The multidrug-resistant yeast Candida (Candidozyma) auris has caused several healthcare-associated outbreaks in the United States. We provide a genomic epidemiologic description of 1,535 C. auris isolates collected in the United States during 2013-2022. We identified clades I, II, III, and IV but not clades V or VI. Median pairwise single-nucleotide polymorphism distances indicated lower intraclade relatedness for clades I (91), III (43), and IV (43), compared with clade II (1,455). Phylogenetic analysis showed regional clusters with varying predominant clades. Of 809 isolates that underwent antifungal susceptibility testing, 53 were echinocandin resistant, distributed across 3 clades; 92% (49/53) had FKS1 hotspot mutations, which varied regionally. Our findings corroborate ongoing transmission and clonal expansion of C. auris, likely propagated by multiple introductions within and between geographic regions. Echinocandin resistance in multiple clades highlights the need to increase awareness, improve treatment practices, and engage in rapid public health response.\n\nID: 42035544\nTitle: Ethyl caffeate reprograms macrophage immunometabolism via the SIRT3-FOXO3A-AKT axis to enhance host defense against Candida auris.\nAbstract: Candida auris (C. auris) is an emerging multidrug-resistant fungal pathogen. Current antifungals are often insufficient, creating a need for host-directed strategies. Sirtuin 3 (SIRT3) is a mitochondrial deacetylase that regulates redox homeostasis, but its role in antifungal macrophage defense is not well defined. We examined how SIRT3 shapes macrophage responses to C. auris. We also evaluated ethyl caffeate (EC) as a host-directed modulator. We used murine macrophages with Sirt3 knockdown or overexpression. We quantified phagocytosis, intracellular fungal survival, mitochondrial ROS dynamics, and macrophage cell integrity using imaging, flow cytometry, CFU assays, and LDH release. We profiled infection-induced transcriptional programs by RNA-seq and performed pathway analyses. We tested EC both in vitro and in systemic infection models in Drosophila and mice. We assessed pathway markers by immunoblotting and immunofluorescence. We used the SIRT3 inhibitor 3-TYP to test inhibition sensitivity. SIRT3 deficiency impaired macrophage antifungal function and was accompanied by redox imbalance. mtROS regulation was disrupted in a biphasic pattern, with an early spike followed by late depletion. Transcriptomics linked SIRT3-dependent programs to FOXO and PI3K-AKT signaling. In macrophages, SIRT3 status tracked with FOXO3A acetylation and AKT phosphorylation. EC showed weak direct antifungal activity in vitro but improved outcomes in systemic infection models. EC treatment increased SIRT3 abundance and was associated with reduced FOXO3A acetylation and restrained infection-associated AKT activation. These functional and signaling effects were largely sensitive to SIRT3 inhibition by 3-TYP. This study connects SIRT3-dependent redox control to FOXO3A-AKT signaling during C. auris infection. It also supports EC as a host-directed candidate that improves antifungal defense in vivo while limiting inflammatory injury.\n\nID: 42026471\nTitle: Susceptibility of Candida auris isolates to antifungal agents: perspectives from whole-genome sequencing and phenotypic testing.\nAbstract: BACKGROUND: Candida auris (Candidozyma auris, C. auris) is a fungal pathogen presenting therapeutic challenges, with multidrug and disinfectant resistance. These traits enable it to persist and be continuously transmitted in the environment, posing significant challenges for preventing and controlling clinical infections. Our study aimed to elucidate the phylogenetic relationships of C. auris isolates collected in China, and to explore the tolerance of C. auris to antifungal drugs and disinfectant agents commonly used in hospital. This study also intended to comprehensively characterize the drug resistance genes and amino acid substitutions in C. auris. METHODS: Whole-genome sequencing was used to identify and construct a phylogenetic tree for 8 strains of C. auris. The minimum inhibitory concentration (MIC) and minimum bacterial concentration (MBC) of antifungal agents against C. auris isolates were determined using broth dilution. Quantitative suspension tests were conducted to evaluate the killing effects of different disinfectant agents on C. auris isolates. Resistance genes and mutation sites were identified using bioinformatic analysis. RESULTS: Five isolates of C. auris were closely related to the C. auris B13916 (clade I) and three isolates were closest to B17721 (clade III). All isolates showed resistance to fluconazole; five of them showed reduced susceptibility to amphotericin B. Compared with Candida albicans, benzalkonium chloride, didodecyl dimethylammonium chloride, chlorhexidine gluconate, and hydrogen peroxide showed increased MIC and MBC values against C. auris isolates. Under specific conditions, the anti-fungal effects of benzalkonium chloride, chlorhexidine gluconate, sodium hypochlorite, ethanol, and povidone-iodine were effective. however, didodecyl dimethylammonium chloride and hydrogen peroxide were less effective. C. auris isolates exhibited amino acid substitutions in ERG11, ERG2, ERG4, CIS2, TAC1, and CDR1. They also possessed resistance genes associated with antimicrobial target alterations and efflux pump. CONCLUSIONS: The decreased susceptibility of C. auris to fluconazole, amphotericin B, didodecyl dimethylammonium chloride, and hydrogen peroxide, which could be attributed to resistance genes and single-nucleotide mutations, reminds medical institutions to rationally select the type, concentration, and exposure time of antifungal agents targeting C. auris. The emergence of C. auris resistance to antifungal drugs and disinfectant agents may involve common molecular mechanisms involving nucleotide mutations, requiring further studies.\n\nID: 42545748\nTitle: Candida auris: An opportunistic fungal pathogen and a priority emergent threat.\nAbstract: Candida auris is an opportunistic yeast causing infections in vulnerable patients leading to high mortality ratio. The Centers for Disease Control and Prevention (CDC) has designated it as a pathogen of concern. The World Health Organization (WHO) has listed it in priority list of fungal pathogens. C.\u00a0auris has the ability to spread very fast inside the hospital environment and cause outbreaks worldwide. It has a very high affinity toward skin colonization, especially in the areas like axilla and groin. Based on whole genome sequencing it is classified into five clades. Each clade has different geographical distribution. Often C. auris gets misidentified as other species due to its phylogenetic similarity with C.\u00a0heamulonii. This can only be resolved by establishing diagnosis at molecular levels. Whole genome sequencing and polymerase chain reaction are some of the important molecular diagnostic methods for detection of C. auris. MALDI-TOF-MS is a culture based highly efficient method that is widely being used for C. auris identification. Treatment of C. auris infection depends on effective antifungal therapy, as multidrug resistance is quite common, the drug regime is decided after antifungal sensitivity testing. It is commonly treated with echinocandins and polyenes. Apart from the antifungal therapy it is also important to monitor the fungemia by performing blood cultures. A strict surveillance system can help prevent the disease. Timely screening of hospital personnel carrying the yeast can contain the spread of this organism. Newer antifungal agents are also required as the organism develops resistance very fast.\n\nID: 42537628\nTitle: Pathogenicity and virulence of Candida auris.\nAbstract: Candida auris (Candidozyma auris) has emerged as a multidrug\u2011resistant human fungal pathogen that causes infections of high morbidity and mortality. Notably, it exhibits a unique ability to grow and persist on human skin, thus leading to efficient transmission through skin-to-skin contact. As a result, C. auris poses a significant risk of outbreaks in healthcare settings, especially in nursing homes that care for elderly patients. Most concerning, C. auris clinical isolates demonstrate widespread and, in some cases, untreatable resistance to all antifungal drug classes, including azoles, polyenes (amphotericin B), and echinocandins. Consequently, invasive C. auris infections cause high mortality rates (30-60%) even with antifungal therapy. Here, we provide a comprehensive overview of candidiasis caused by C. auris, discussing both host and pathogen determinants of skin colonization, as well as key challenges associated with preventing dissemination and management of disseminated fungal infections.\n\nID: 42522315\nTitle: Phytochemicals as Novel Antifungal Agents Against Candida species.\nAbstract: Infections caused by Candida, including vulvovaginal candidiasis (VVC) and invasive candidiasis (IC), are a growing public health problem, exacerbated by multidrug resistance, biofilm persistence, and the limited development of antifungal drugs. In this review, we discuss plant-derived natural products with potent anti-Candida activity, specifically terpenoids, alkaloids, flavonoids, phenolics, and their nanoformulations. Many compounds, including berberine, artemisinin, thymol, eugenol, carvacrol, quercetin, catechins, lawsone, and caffeic acid, have shown the ability to modulate the fundamental mechanisms of fungal growth, which include disrupting membranes, inhibiting ergosterol biosynthesis, modulating efflux pumps, inducing oxidative stress, and biofilm inhibition. Some phytochemicals also demonstrate synergism with azoles, polyenes, and echinocandins, which can support dose reduction and restoration of resistance. Ultimately, while there is supportive preclinical evidence for anti-Candida action via the aforementioned compounds, clinical translation has been limited due to issues concerning standardization of use, pharmacokinetic variability, and toxicity issues. Some recent advances in nano-delivery systems, structural bioactivity modifications, and molecular docking studies provide a path forward when considering ways to maximize antifungal properties and improve bioavailability. This review highlights current advancements, therapeutic opportunities, and critical research gaps to accelerate the integration of phytochemicals into antifungal stewardship and device-associated infection control strategies.\n\nID: 42513906\nTitle: Comparative Analysis of Virulence Traits and Fluconazole-Response Mechanisms in Clinical Isolates of Candidozyma auris.\nAbstract: Candidozyma auris (formerly known as Candida auris) has emerged as a formidable clinical fungal pathogen as a result of its multidrug resistance and persistent colonization capabilities. In this study, three clinical C. auris strains (namely C. auris strain 01, C. auris strain 03, and C. auris strain 13) with distinct origins were characterized to investigate their phenotypic variations and mechanisms of azole resistance. Comprehensive profiling revealed significant inter-strain differences in biofilm formation, cell surface hydrophobicity, adhesion capacity, and phospholipase activity. Testing for antifungal susceptibility showed that the three clinical strains exhibited different minimum inhibitory concentrations for multiple azoles (fluconazole, voriconazole, and itraconazole) and echinocandins (anidulafungin and micafungin). Sequencing identified Y132F mutations in the ERG11 gene of the three clinical strains. Mechanistic investigations demonstrated that fluconazole exposure significantly upregulated the expression of efflux pump genes (CDR1 and CDR2) and the genes encoding their transcriptional regulators (MDR1 and TAC1b). In a murine skin colonization model, comparing data from the standard strain C. auris strain CBS12766 and clinical strains of C. auris strain 03 and C. auris strain 13 exhibited a significantly higher fungal burden of tissue, whereas strain C. auris strain 01 showed an intermediate level. Host immunity response analysis revealed that expression of the IL-1\u03b2 gene was significantly elevated in C. auris strain CBS12766-infected mice, while expression of IL-6 and CXCL-1 genes was predominantly increased in the C. auris strain 01, with TNF-\u03b1 gene expression levels being comparable across all strains. Histopathological examination confirmed local infiltration of inflammatory cells and mild epidermal edema, indicating active host immune engagement. Overall, our findings highlighted substantial phenotypic heterogeneity, different colonization capacities, and differences in expression of inflammatory cytokines among the C. auris strains. Further investigations into fluconazole-response mechanisms identified enhanced efflux pump activity, along with ERG11 gene Y132F mutations and transcription factor modulation among these clinical strains.\n\nID: 42487702\nTitle: Differentiation of Candida auris from other pathogenic yeasts using near-infrared spectroscopy and multivariate analysis: a proof-of-concept study.\nAbstract: Candida (Candidozyma) auris has emerged as a major public health concern due to its multidrug resistance, high mortality rates, and outbreak potential. These challenges are intensified by the difficulty of accurately identifying this species, particularly in settings with limited laboratory resources. This difficulty arises because C. auris is closely related to other yeast species, such as those within the Candida haemulonii complex. Although we previously demonstrated that near-infrared spectroscopy (NIRS) combined with multivariate analysis can discriminate C. auris from C. haemulonii stricto sensu, its performance against other clinically important yeasts had not been evaluated. In this study, we assessed NIRS coupled with different multivariate analytical techniques as a tool for distinguishing C. auris from C. haemulonii, C. albicans, C. tropicalis, C. parapsilosis, Nakaseomyces glabrata (formerly C. glabrata), and Pichia kudriavzevii (formerly C. krusei). Each of the seven species was cultured on fifteen Sabouraud Dextrose agar plates at 37 \u00b0C. After 72 h, three isolated colonies per plate (45 colonies per species) were subjected to Fourier-transform NIR analysis, resulting in a total of 315 spectra. The spectra were preprocessed and analyzed using principal component analysis (PCA), successive projections algorithm (SPA), genetic algorithm (GA), and linear discriminant analysis (LDA) to construct classification models. The combination of PCA, SPA, and GA with LDA achieved 100% sensitivity, specificity, and accuracy. These findings demonstrate that NIRS coupled with multivariate analysis can reliably differentiate C. auris from other medically important yeasts. The models also showed strong discriminatory capacity among the most prevalent pathogenic yeast species, reinforcing the promise of this approach as a rapid diagnostic tool for overcoming current identification challenges.\n\nID: 42474134\nTitle: Pharmacological advances in Candida auris: emerging antifungal mechanisms and next-generation therapeutic strategies.\nAbstract: Candida auris is a major public health concern worldwide due to its efficient transmission, environmental persistence, and broad resistance to approved antifungal classes. This review consolidates recent pharmacological developments in this regard, focusing on mechanistic insights and late-stage therapeutics. Novel agents demonstrate activity against multidrug- and pan-resistant isolates via distinct mechanisms of action and enhanced specific binding to CYP51. Repositioned drugs, host-defense peptides, and quorum-sensing modulators also expand the treatable spectrum, particularly for biofilm-associated and device-related infections. Concurrently, artificial intelligence (AI)-guided discovery, nanocarrier-enabled delivery, and multi-omics profiling are greatly accelerating target identification and enhancing the drug metabolism of small-molecule fragments. The emerging combined approaches mark a transition towards mechanism-based antifungal development to combat the increasing clinical burden posed by C. auris. Ongoing integration of precision diagnostics, pharmacodynamic optimization, and novel discovery platforms will be key to translating these advances into durable, real-world therapeutic solutions.\n\nID: 42390249\nTitle: Disinfectant tolerance of Candidozyma auris and Candida albicans biofilms evaluated using the bead assay for biofilms.\nAbstract: Candidozyma auris (formerly Candida auris) has emerged as a critical nosocomial pathogen, notable for its multidrug resistance and its capability to form biofilms that enable persistence on surfaces. Although effective disinfection strategies are urgently needed, current disinfectant efficacy standards in many regions, such as Europe, are primarily based on testing planktonic Candida albicans and do not adequately reflect the resilience of Candida biofilms, including those of C. albicans and C. auris. To address this gap, the Bead Assay for Biofilms, previously developed for bacterial biofilms, was adapted for the first time to eukaryotic cells. The goal was to cultivate C. auris and C. albicans biofilms and evaluate the efficacy of selected disinfectants across four active substance classes. Cell enumeration demonstrated highly reproducible biofilms, whose architecture was confirmed by scanning electron microscopy. Both an alcohol- and a QAC-based product did not achieve sufficient reduction of at least \u22654 log10 CFU/mL of biofilm-cells when applied under conditions recommended by the manufacturer (alcohol 1 min: C. auris 0.82, C. albicans 0.54; QAC 1%, 15 min: C. auris 1.94, C. albicans 0.68). This reduced efficacy is consistent with the known increased tolerance of microorganisms in biofilms. In contrast, peracetic acid and glutaraldehyde achieved sufficient reductions, albeit at relatively high concentrations (peracetic acid 0.1%: C. auris 4.75 and 0.05%: C. albicans 4.87; glutaraldehyde 0.5%: C. auris 5.32 and C. albicans 4.15). Our findings underscore the need to adapt disinfection protocols and testing models to consider biofilm formation of C. auris and C. albicans, and species-specific resilience.IMPORTANCEThis study highlights a critical gap in current disinfection efficacy testing standards; many of which rely on planktonic cell models and do not account for the resilience of biofilm-associated cells or emerging pathogens with unique resistance traits. Although species-specific regulatory guidance for C. auris exists in certain regions (e.g., in the USA), standardized disinfectant testing remains largely based on suspension assays (often using C. albicans) and does not routinely incorporate biofilm models. Using the Bead Assay for Biofilms, we demonstrate that several commonly used disinfectants may fail to inactivate biofilm-associated C. auris and C. albicans when applied as recommended. This suggests that reliance on planktonic testing may overestimate disinfectant efficacy against clinically relevant pathogenic yeast and highlights the need to expand current testing standards in order to include biofilm-associated pathogens to improve infection prevention strategies. Consequently, our research is of immediate relevance to regulatory bodies, infection control, and public health.\n\nID: 42382872\nTitle: Candida auris in a Tertiary Care Hospital in Oman: A Five-Year Study of Epidemiology, Clinical Characteristics, and Antifungal Susceptibility.\nAbstract: Background Candida auris\u00a0(C. auris)\u00a0is an emerging multidrug-resistant pathogen known for causing persistent colonization, invasive infections, and healthcare-associated outbreaks. Its ability to survive in hospital environments, resist common antifungals, and affect critically ill patients makes it a major global health concern. Understanding local epidemiology and susceptibility patterns is essential to guide prevention and management strategies. Objective This study aimed to describe the temporal distribution and antifungal susceptibility patterns of\u00a0C. auris\u00a0at a tertiary care hospital in Oman (2017-2021) and compare clinical characteristics, risk factors, and outcomes between colonized and infected patients, including candidemia and non\u2011candidemia subgroups. Methods This retrospective, single\u2011center study included all patients with at least one C. auris-positive culture at Khoula Hospital, a tertiary care hospital in Oman (2017-2021). Species identification and susceptibility testing were performed using the VITEK\u00ae 2 system (bioM\u00e9rieux,\u00a0Marcy-l'\u00c9toile,\u00a0France) and confirmed at the Central Public Health Laboratories. Clinical and epidemiologic data were extracted from electronic medical records. Patients were classified as colonized or infected based on clinical and microbiologic findings, and the infected group was further subclassified into candidemia and non-candidemia subgroups. Statistical comparisons used Mann-Whitney U, chi-square, or Fisher's exact tests, and odds ratios (OR) with 95% confidence intervals (CI) were calculated for categorical variables, with significance at p < 0.05. Results A total of 129 patients (130 isolates) were identified. Cases peaked in 2019 and declined thereafter. Of all patients, 51 (39.5%) had confirmed infection, and 78 (60.5%) were colonized. Candidemia was the predominant invasive presentation (39/51, 76.5%). Infected patients had longer hospitalization (median, 73 versus 57.5 days;\u00a0p = 0.027) and higher central venous catheter\u00a0use (74.5% versus 56.4%; OR, 2.25; 95% CI, 1.04-4.89;\u00a0p = 0.037) than colonized individuals. Crude mortality was higher in infected than colonized patients (43.1% versus 28.2%, p = 0.080). Among infected patients, candidemia was associated with greater mechanical ventilation use (94.9% versus 66.7%; OR, 9.25; 95% CI, 1.44-59.51;\u00a0p = 0.008) and central-line utilization (82.1% versus 50.0%; OR, 4.57; 95% CI, 1.13-18.47;\u00a0p = 0.026). Crude mortality was higher in candidemia than non-candidemia infections (48.7% versus 25.0%, p = 0.14). Susceptibility testing showed universal fluconazole resistance (100%), very limited amphotericin B activity (5.2%), intermediate voriconazole susceptibility (44.8%), and preserved echinocandin activity (caspofungin, 96.6%; micafungin, 100%) and flucytosine activity (80.0%). Conclusions The findings demonstrate that C. auris imposes a considerable burden on hospitalized patients, with marked morbidity in those who develop invasive disease, particularly candidemia. The organism's persistent multidrug resistance, with its capacity for sustained transmission, highlights the need for strengthened infection-control practices and continuous surveillance. Preservation of echinocandin susceptibility supports their role as first-line therapy, while high prevalence of azole and amphotericin B resistance emphasizes the importance of targeted antifungal stewardship and early risk identification to reduce both transmission and adverse clinical outcomes.\n\nID: 42378120\nTitle: Surveillance for Candida auris - United States, 2022-2024.\nAbstract: Candida auris is an emerging yeast that is frequently resistant to antifungal drugs. C. auris can cause invasive infections associated with high mortality and can colonize patients asymptomatically, which facilitates transmission in health care settings. Since it was first reported in the United States in 2016, C. auris has been identified in multiple states, with increasing numbers of cases reported annually. Monitoring national trends in cases identified through clinical testing and screening for colonization is critical to guide infection prevention and control efforts. 2022-2024. State and jurisdictional health departments voluntarily report clinical and screening C. auris cases to CDC using standardized case definitions of the Council of State and Territorial Epidemiologists. Clinical cases are defined as detection of C. auris from specimens collected for diagnostic purposes; screening cases are defined as detection from colonization screening swabs. Cases were reported to CDC through the Research Electronic Data Capture (REDCap) or Data Collation and Integration for Public Health Event Response (DCIPHER) platforms. Data included patient age and sex, case type, specimen type (for clinical cases), health care facility type, Antimicrobial Resistance Laboratory Network geographic region, and specimen collection date. Analyses were descriptive and limited to cases with specimens collected during 2022-2024. During 2022-2024, a total of 13,507 clinical C. auris cases were reported to CDC, increasing from 2,882 in 2022 to 4,428 in 2023 and 6,197 in 2024, with smaller annual percentage increases over time (53.7% from 2022 to 2023 and 39.9% from 2023 to 2024). Most clinical cases occurred among adults aged \u226545 years (87.8%) and among males (61.0%). The most common specimen types among all clinical cases were urine (31.5%) and blood (30.2%); by year, the proportion of blood as the specimen type was 34.4% in 2022, 30.2% in 2023, and 25.6% in 2024. Most clinical cases were identified through specimens collected in acute care hospitals (76.6%) and long-term acute care hospitals (17.8%).During the same period, a total of 27,853 screening cases were reported to CDC, increasing from 6,226 in 2022 to 9,195 in 2023 and 12,432 in 2024. Screening cases most frequently occurred among adults aged \u226545 years (90.0%) and males (57.9%). Among cases with known facility type, the proportion of specimens collected in acute care hospitals increased from 24.7% in 2022 to 50.7% in 2024, whereas the proportion of specimens collected in long-term acute care hospitals decreased from 56.1% to 35.7% during the same period. The number of clinical and screening C. auris cases reported to CDC increased during 2022-2024, indicating ongoing transmission in U.S. health care settings. Although annual percentage increases in clinical cases declined over time, absolute case counts reported to CDC continued to rise. The increasing proportion of screening cases with specimens collected in acute care hospitals might reflect increased use of screening in acute care hospitals, including screening at admission. Because of increases in the number of reported C. auris cases, sustained infection prevention and control efforts in health care facilities, including adherence to transmission-based precautions, environmental disinfection with agents effective against C. auris, and communication of C. auris status during patient transfers remain essential to preventing clinical infections and colonization. Because this pathogen is frequently resistant to antifungal drugs, continued investment in laboratory capacity and surveillance, including antifungal susceptibility testing and screening of patients at high risk for C. auris infection, can support timely detection and guide prevention strategies. Ongoing public health coordination at federal, state, and local levels is critical to limit further spread and to address emerging antifungal drug resistance.\n\nID: 42366948\nTitle: Colonization with multidrug-resistant organisms (MDROs) including Candidozyma auris among residents in ventilator-designated versus non-ventilator-designated beds at skilled nursing facilities (SNFs).\nAbstract: Across 13 surveys of 590 residents in seven ventilator-capable SNFs, residents in ventilator-designated beds had markedly higher ESBL (48.1% vs 28.2%; aOR = 1.64) and C. auris (38.6% vs 15.2%, aOR = 2.89), but lower MRSA colonization (35.2% vs 45.5%; aOR = 0.47), supporting the need for MDRO prevention beyond current Enhanced Barrier Precautions.\n\nID: 42349794\nTitle: Response to Wu et al \"Clinical Potential of Antimicrobial Photodynamic Therapy\".\nAbstract: \n\nID: 42348119\nTitle: Unraveling clade-specific differences in Candida auris: evolution, adaptation, and pathogenicity.\nAbstract: Since its 2009 emergence, Candida auris (now also known as Candidozyma auris) has evolved from a rare isolate into a global \"critical priority\" pathogen. This rapid expansion is defined by its unique population structure consisting of six distinct genomic clades with starkly different evolutionary trajectories, phenotypic traits, and clinical risks. We conducted a systematic synthesis of literature from PubMed, Scopus, and Google Scholar (2009-2026), focusing on comparative genomics, clade-specific virulence, and diagnostic accuracy. A total of 64 studies were analyzed to identify patterns in clade divergence and antifungal resistance. Our analysis reveals that C. auris is not a monolithic threat but a complex of diverse lineages with specialized adaptations. Clade I (South Asian) and Clade IV (South American) represent the highest clinical risk due to hyper-virulence and high rates of multi-drug resistant (MDR) strains. In contrast, Clade II (East Asian) was initially associated with localized ear infections; recent genomic data show an expanding pathogenic profile with emerging bloodstream infections. Our review also identifies Clade V (Iranian) as a genetically distinct group and highlights the recent identification of Clade VI (Indomalayan) as a distinct lineage, suggesting a long-standing environmental reservoir. Furthermore, we identify critical \"blind spots\" in automated diagnostic platforms (VITEK\u00ae 2, BD Phoenix) where phenotypic variations in Clades II and III lead to frequent misidentification as Candida haemulonii or Candida famata. This review proposes a \"clade-aware\" framework for public health. While frontline antifungal treatment remains standardized regardless of lineage, we argue that effective long-term management and outbreak containment require integrating genomic surveillance with clade-specific infection control. By identifying high-biofilm clades (Clade I) or hyper-virulent lineages (Clade IV), public health systems can implement more targeted containment strategies, moving toward a precision-based approach to managing this fungal pathogen.\n\nID: 42346566\nTitle: Recent Outbreaks, Resistance Trends, and Control Measures in Candida auris and Candida glabrata Infections.\nAbstract: The global rise in multidrug-resistant (MDR) fungal pathogens has positioned Candida auris and Candida glabrata as major threats to public health. In recent years, these pathogens have increasingly been reported beyond traditional hospital settings, including neonatal intensive care units, long-term care facilities, oncology wards, and post-pandemic critical care environments. International surveillance bodies, including the Centers for Disease Control and Prevention (CDC), European Centre for Disease Prevention and Control (ECDC), World Health Organization (WHO), and regional monitoring networks, have documented escalating antifungal resistance, complex outbreak dynamics, and persistent gaps in infection control implementation. C. auris has emerged as a major etiological agent of healthcare-associated outbreaks, particularly in intensive care and neonatal units. Surveillance data indicate that a high proportion of C. auris isolates exhibit resistance to azoles, often exceeding 80% in some regions, while echinocandin resistance remains variable. Resistance patterns have evolved from predominantly azole resistance to broader multidrug-resistant phenotypes, including treatment-emergent echinocandin resistance. Six genetically distinct clades (I-VI) have been identified, with Clades I, III, and IV associated with large-scale outbreaks, whereas available data suggests that Clades II, V, and VI are more geographically restricted, although evidence for the recently described clades remains limited. C. glabrata is increasingly recognized as a major cause of invasive candidiasis, with rising resistance reported across multiple regions. While reduced azole susceptibility was historically predominant, emerging evidence highlights rising dual azole-echinocandin resistance, adaptive microevolution during antifungal therapy, and biofilm-associated tolerance mechanisms. Despite these advances, significant gaps persist in global resistance surveillance and in the mechanistic understanding of virulence and antifungal adaptation. Current mitigation strategies include antifungal stewardship programs, expanded resistance testing, and strengthened surveillance systems. Advances in rapid diagnostic technologies such as matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry, polymerase chain reaction (PCR)-based assays, and genomic surveillance have improved pathogen identification and outbreak detection, although accessibility remains limited in resource-constrained settings. This review examines emerging epidemiological, genomic, and antifungal resistance trends in C. auris and C. glabrata and highlights key priorities for improving diagnosis, surveillance, stewardship, and management of multidrug-resistant Candida infections.\n\nID: 42296425\nTitle: Increasing threat to the healthcare setting: Candida auris.\nAbstract: This review summarizes the current knowledge related to infection prevention for Candida auris in the healthcare setting. Colonization, pathogenesis, and control strategies are discussed. There are numerous well documented C. auris outbreaks in healthcare settings, however, evidence is lacking on how to manage these colonized and postinfection patients long term in the acute care setting. C. auris is an emerging fungal pathogen with unique characteristics that make it challenging to eradicate in healthcare settings once introduced. Mitigation and control strategies have been investigated, but more research is needed about tangible effects of skin colonization, environmental disinfection, duration of transmission-based precautions, and topical decolonization.\n\nID: 42291323\nTitle: Analysis of the knowledge, attitudes, and practices of intensive care unit staff regarding Candida auris: a mixed-methods study in a private general hospital in Hanoi, Vietnam.\nAbstract: Candida auris, recently renamed Candidozyma auris, is an invasive fungal pathogen that is on the priority list on the World Health Organization (WHO) for future research. Infection poses major diagnostic and treatment challenges due to its phenotypic similarity to other Candida spp. and multiple antifungal resistance. Despite its emergence in Vietnam, the level of understanding among healthcare professionals is unknown. This study explores the knowledge, attitudes, and practices toward C. auris of registered physicians and nurses in a Vietnamese hospital intensive care unit (ICU). A mixed-methods study was conducted in an international standards-accredited Hanoi private general hospital. It comprised a self-administered cross-sectional survey containing 46 questions distributed to the ICU staff, followed by an in-depth semi-structured interview of selected participants. The survey covered demographic, knowledge, attitudes, and practices domains and utilized Likert-type and ranking scales. Descriptive and analytical statistics were applied to quantitative data and thematic analysis to qualitative insights. A total of 32 ICU staff completed the survey, but only 11 (34.38%) scored above 50%. Knowledge was associated weakly with age and work experience but not gender or profession. Most participants recognized C. auris as an important ICU pathogen and expressed a positive attitude to institutional preparedness but revealed confusion about the site of infection, means of diagnosis, most effective agents for treatment, and best PPE practices to prevent infections. Of the 12 participants selected for in-depth interview, only two were familiar with the WHO guidelines on C. auris. The concerns centered on access to treatment, especially for immunocompromised patients. The opinions on outbreak likelihood varied, with some staff citing poor infection control in public hospitals as a risk, while others considered an outbreak unlikely due to low prevalence and the restricted mode of transmission. For multiple reasons, the private sector was perceived as better prepared than the public sector. This study reveals a knowledge gap regarding C. auris among ICU physicians and nurses in Hanoi caring for high-risk patient populations. The findings underscore a need for targeted continuing medical education, enhanced antifungal stewardship strategies, and revised infection control protocols to combat this clinically important emerging pathogen in Vietnamese hospitals.\n\nID: 42269828\nTitle: Liposomes loaded with Cymbopogon nardus L. Rendle essential oil: Characterization and potential in vitro and in vivo action against Candidozyma auris.\nAbstract: The rapid dissemination of Candidozyma auris (previously known as Candida auris) and its multidrug resistance profile poses a significant challenge in therapy once it contributes to a mortality of 30-60% of infected patients. This study aimed to evaluate the in vitro and in vivo antifungal activity of Cymbopogon nardus (L.) Rendle essential oil and citral oil, both free and incorporated into liposomes, against C. auris. The liposomes were composed of a lipid phase containing soy phosphatidylcholine, ergosterol, cholesterol and oleylamine, along with an aqueous phase consisting of PBS. The liposome was characterized by measuring the following features: hydrodynamic size, polydispersity index, zeta potential, transmission electron microscopy, infrared vibrational spectroscopy, thermogravimetry and differential scanning calorimetry, and transmission electron microscopy. The antifungal activity of the C. nardus essential oil, the citral oil and liposome-loaded compounds was determined by minimum inhibitory concentration (MIC), biofilm assay and by a Galleria mellonella infection model. G. mellonella was also used to assess acute in vivo toxicity. The liposomes exhibited sizes ranging from 218.8 to 261.7nm, polydispersity index <0.5, and a positive zeta potential. Furthermore, the liposomes showed good stability and a lipid layer in the outer region. Citral showed the best antifungal activity, with MIC 62.5\u03bcg/mL, being the compound selected for its incorporation into liposomes, which further improved its antifungal potential. Citral and citral-liposomes showed important metabolic inhibition in mature biofilms (20%). No acute toxicity was observed for either sample in G. mellonella, and citral-liposomes showed promising antifungal action in the G. mellonella infection model. Liposomes represent a promising strategy for the safe and effective delivery of citral to control C. auris infection.\n\nID: 42267094\nTitle: Prevalence, pattern of disease and antimicrobial susceptibility of Candidozyma auris in the greater Pretoria region from 2021 to 2024.\nAbstract: Candidozyma auris has emerged as a nosocomial pathogen in South Africa, characterised by multidrug resistance and environmental persistence. This study aimed to describe the prevalence, disease patterns, and antifungal susceptibility patterns of C. auris isolates recovered from public-sector healthcare facilities in the greater Pretoria region from 2021 to 2024. A retrospective laboratory-based surveillance study was conducted using data from the National Health Laboratory Service Tshwane Academic Division laboratory. Isolates were classified as invasive or non-invasive based on specimen source. Temporal trends in antifungal minimum inhibitory concentrations (MICs) were analysed using interval-censored regression. A total of 592 C. auris isolates were identified. Blood cultures were the most frequent specimen source overall, comprising 237 isolates (40.03%). Intravascular catheter tip isolates predominated in 2023 and 2024, with 48 and 72 isolates, respectively. The proportion of invasive isolates declined from 56.8% to 40.8% over the study period. Among tested isolates, fluconazole resistance exceeded 99%. Resistance to amphotericin B and echinocandins was uncommon, with eight total isolates identified. Decreasing MIC trends were observed for amphotericin B (\u03b2 = -0.059 per year; p = 0.012) and micafungin (\u03b2 = -0.081 per year; p = 0.026). Candidozyma auris remains established in the public-sector within the greater Pretoria region. There is a shift from invasive bloodstream infections towards non-invasive, device-associated isolates. Fluconazole resistance remained high while amphotericin B and echinocandins retained good in vitro activity. This study contributes to the knowledge of C. auris in the greater Pretoria region, providing insight into epidemiology and antifungal susceptibility.\n\nID: 42211613\nTitle: Epidemiology, Distribution, Key Characteristics, and Challenges of Candidozyma auris (Formerly Candida auris): A Narrative Review With a Special Focus on T\u00fcrkiye.\nAbstract: This narrative review summarizes the epidemiology, microbiological and clinical features, antifungal resistance, transmission dynamics, and public health significance of Candidozyma auris globally and with a focus on T\u00fcrkiye. C. auris has emerged as an important fungal pathogen because of its capacity for healthcare-associated colonization, environmental persistence, biofilm formation, laboratory misidentification, and multidrug resistance. Available evidence suggests that its rapid global spread is related to environmental tolerance, skin colonization, interclade phenotypic differences, and antifungal resistance mechanisms. Reported cases from T\u00fcrkiye further support the need for strengthened infection control and surveillance systems. It represents a significant nosocomial fungal threat that necessitates the simultaneous implementation of clinical management and public health responses. In addition, it has been observed that the dominant clade in T\u00fcrkiye is Clade I, that early cases were misidentified due to laboratory method-related limitations, and that there are substantial variations in antifungal susceptibility even within the same case series.\n\nID: 42208142\nTitle: Candida (Candidozyma) auris in pediatric population: risk factors, clinical presentation, and outcomes.\nAbstract: Candida (Candidozyma) auris, identified as a human pathogen in 2009, has emerged as a significant nosocomial fungus due to its multidrug resistance and diagnostic challenges. It is associated with invasive infections, particularly in critically ill patients exposed to broad-spectrum antibiotics and invasive procedures. Pediatric patients in intensive care units are at increased risk owing to the use of mechanical ventilation, parenteral nutrition, central venous catheters, and antimicrobial agents. A systematic review of the literature was conducted in the PubMed, Embase, and Scopus databases between January 2011 to January 2025. Sixteen studies met the inclusion criteria, totaling 110 pediatric cases of C. auris infection. Most cases were reported in Colombia (45.5 %), followed by the United States (18.1 %) and Venezuela (15.4 %). Coinfections were identified in 10.9 % of cases, mainly involving Enterobacter spp., Klebsiella spp., and Staphylococcus spp. Bloodstream infection was the main clinical presentation (93.6 %), and the median time to isolation of C. auris was 20.3 days. The most commonly used antifungals in isolated cases were voriconazole (38.9 %), amphotericin B (35.2 %), and caspofungin (33.3 %). Mortality was 39.1 %, while 52.7 % survived. Multiple antifungal combinations have been reported, with amphotericin B and micafungin being the most common. Among 33 clinical isolates, high resistance to fluconazole (60.6%) and variable susceptibility to amphotericin B were observed. Echinocandins, such as micafungin and anidulafungin, showed greater efficacy, although resistance to caspofungin has been reported. C. auris in pediatric patients represents a growing challenge, especially in preterm neonates, due to high antifungal resistance and diagnostic difficulties.\n\nID: 42548967\nTitle: Qdr3 Coordinates cellular homeostasis, mitochondrial remodeling, and virulence in Candidozyma auris (Candida auris).\nAbstract: Qdr3 acts as a global regulator in Candidozyma auris (Candida auris), coordinating mitochondrial function and cell-surface architecture.

Since its initial discovery in 2009, C. auris has spread rapidly across continents and is now classified by both the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO) as a critical-priority pathogen. This review summarizes current knowledge on the origin, taxonomy, microbiology, and virulence mechanisms of C. auris, emphasizing its thermotolerance, osmotolerance, and biofilm-forming capacity on biotic and abiotic surfaces, as well as aspects related to its antifungal drug resistance and management. These features, together with its genomic plasticity, contribute to persistence, transmission, and drug resistance. Emerging evidence also supports a potential link between climate change and C. auris evolution, highlighting environmental adaptation as a driver of pathogenicity. Combating C. auris will require multidisciplinary efforts to mitigate its expanding global impact.\n\nID: 42003753\nTitle: The Epidemiology and Infection Control of Candida Auris in Shanghai.\nAbstract: Candida auris is a globally emerging multidrug-resistant fungus. Its dissemination is driven by patient movement and asymptomatic carriers. However, molecular epidemiological studies linking imported cases to local strains in large metropolitan areas remain limited. To analyse the molecular epidemiology and resistance mechanisms of 33 clinical isolates in Shanghai and propose an integrated infection control strategy tailored to metropolitan healthcare settings. Isolates from 19 patients were identified via MALDI-TOF MS and sequencing. Antifungal susceptibility and biofilm formation were assessed. Environmental contamination was evaluated using PCR. Whole-genome sequencing (WGS) was employed to identify resistance mutations and perform phylogenetic analysis. All 33 isolates were fluconazole-resistant. Resistance to amphotericin B and echinocandins was observed in 9 and 4 isolates, respectively. All echinocandin-resistant strains harboured the Fks1-S639F mutation. Phylogenetic analysis revealed that Clade III (South African clade) was the dominant lineage. Colonisation was concentrated in the urinary tract and inguinal regions, while bedside tables were identified as key environmental reservoirs. All strains exhibited strong biofilm-forming capacity. ICU patients serve as primary reservoirs, with transmission driven by interregional movement. The distinct colonisation patterns and environmental hotspots provide specific targets for screening. Integrating PCR-based environmental monitoring with culture methods constitutes an effective strategy. These findings underscore the need for a standardised protocol integrating molecular diagnostics to optimise infection control in urban hospitals.\n\nID: 42003596\nTitle: Role of the transcription factor Wor2 in biofilm formation of Candidozyma auris.\nAbstract: The yeast pathogen Candidozyma (Candida) auris can form biofilms, which contribute to its virulence and nosocomial transmission. In this study, we identified the transcription factor Wor2 as a negative regulator of biofilm formation in C. auris. Wor2 hyperactivation in a strain of clade IV via the use of a protein tagging strategy resulted in downregulation of two important adhesins, SCF1 and ALS4112, and decreased biofilm-forming capacity. We showed that the impact on biofilm was predominantly mediated via decreased SCF1 expression in this strain. However, results of adhesion assays on inert surfaces and human keratinocytes found relatively modest roles of Wor2 and Scf1 in this process, suggesting that their effect on biofilm formation is complex and not limited to the adhesion step. Finally, analyses of other strains from different clades identified three distinct WOR2 genotypes, with variable WOR2 expression levels and distinct impacts of WOR2 deletion on biofilm formation. Notably, Wor2 negatively regulated biofilm in strains of clades I, III, and IV with distinct profiles of SCF1/ALS4112 expression, while it had no impact on biofilm in a clade II strain. Taken together, this study showed that Wor2 exhibited some distinct genotypic evolution in C. auris resulting in clade- or strain-specific regulatory roles and pathways in biofilm formation.IMPORTANCECandidozyma (Candida) auris is a pathogenic yeast exhibiting a particular capacity for interhuman transmission via medical instruments, which was the cause of nosocomial outbreaks of candidemia. Adhesion to inert surfaces and subsequent biofilm formation is therefore important for C. auris propagation. This work highlights the role of the transcription factor Wor2 as a negative regulator of biofilm formation in C. auris. In a strain of clade IV, Wor2 was shown to downregulate two important adhesins (SCF1 and ALS4112). Interestingly, Wor2 exhibited different genotypes across C. auris clades and strains, which were associated with distinct differential expression of WOR2, ALS4112, and SCF1, and possibly distinct roles in biofilm formation.\n\nID: 41983685\nTitle: Liquid-infused silicone catheters reduce fungal burden and inflammation in Candidozyma auris bladder infections.\nAbstract: Candidozyma auris is a high-priority, emerging fungal pathogen frequently isolated from urine in healthcare settings. These isolates are often associated with indwelling urinary catheters, a primary risk factor for catheter-associated urinary tract infections (CAUTIs). Despite its clinical prevalence, the mechanisms of C. auris colonization and pathogenesis within the bladder remain poorly understood. In this study, we screened C. auris isolates from diverse clades using an in vitro biofilm model and in vivo murine models of uncomplicated UTI and CAUTI. While in vitro biofilm formation varied among isolates, the presence of a catheter in vivo significantly enhanced fungal burden in the bladder. Notably, one strain (B11103) caused rapid systemic dissemination and mortality. To address this, we evaluated a liquid-infused silicone (LIS) catheter coating, which has previously shown efficacy against other uropathogens. The LIS coating significantly reduced C. auris attachment in vitro and, crucially, mitigated fungal burden on both the catheter and bladder tissue in vivo across all tested strains. For the hypervirulent B11103 strain, LIS catheters also significantly reduced dissemination to the kidneys and bloodstream. Furthermore, cytokine analysis revealed that C. auris CAUTI upregulates IL-6, CSF3, and CXCL1; importantly, this damaging inflammatory response was also dampened by the LIS catheter. These findings demonstrate that catheterization potentiates C. auris pathogenicity and identify LIS catheters as a promising, antimicrobial-sparing strategy to prevent colonization, systemic spread, and inflammation during C. auris CAUTI.IMPORTANCEThis research addresses the critical public health challenge posed by the emergence of Candidozyma auris, elucidating its pathogenesis in the urinary tract, the second-most common yet understudied reservoir. Here, we find that C. auris exhibits plasticity in its ability to form biofilms in urine and cause uncomplicated urinary tract infections (UTIs) and catheter-associated UTIs (CAUTIs). Importantly, we show that our liquid-infused silicone (LIS) catheters effectively disrupt this cycle by reducing fungal burden, preventing systemic spread, and dampening the damaging host inflammatory response. This work establishes the urinary tract as a critical niche for systemic entry and provides a validated strategy for infection prevention. Urinary catheters make C. auris dangerous, but this liquid-infused silicone coating is fighting back.\n\nID: 41979352\nTitle: Harnessing random peptide mixtures to combat multidrug-resistant fungal infections.\nAbstract: Invasive fungal infections are associated with high mortality and are increasingly difficult to treat due to a limited antifungal arsenal and the rapid emergence of drug resistance. Novel therapeutic strategies that combine potent antifungal activity, low host toxicity, in vivo stability, and a reduced propensity for resistance development are urgently needed. Antimicrobial peptides (AMPs) stand out as a promising class of compounds to combat antimicrobial resistance. Leveraging the unique properties of AMPs, we previously developed a novel approach to synthesize random peptide mixtures (RPMs) with robust bactericidal activity against drug-resistant bacteria. Here, we evaluate the antifungal potential of RPMs and demonstrate species-dependent, broad-spectrum activity of FK20 (L-phenylalanine-L-lysine, 20-mer) against major human fungal pathogens, including Candida spp., Cryptococcus neoformans, and Aspergillus fumigatus, with particularly high potency against the multidrug-resistant pathogen Candida auris. Mechanistic analyses revealed rapid membrane and cell wall disruption accompanied by intracellular penetration, consistent with membrane-active antifungal activity. Importantly, experimental evolution assays demonstrated a markedly reduced capacity for resistance development in C. auris. FK20 inhibited biofilm formation and displayed substantial activity against mature, pre-formed biofilms, both alone and synergistically in combination with caspofungin. Finally, FK20 showed significant therapeutic efficacy in a murine model of systemic candidiasis. Collectively, these findings establish RPMs as a versatile antifungal platform with broad-spectrum activity, biofilm efficacy, and a low resistance footprint, highlighting their promise as a novel therapeutic strategy against drug-resistant fungal infections. The rising prevalence of invasive fungal infections, particularly among immunocompromised individuals, has become a critical public health concern. However, antifungal drug development has not kept pace with this growing need, and treatment options remain limited to a small number of drug classes. The emergence of multidrug-resistant fungal pathogens, such as Candida auris, further exacerbates this crisis by reducing the efficacy of existing therapeutics and increasing the risk of treatment failure. In this study, we evaluate the antifungal potential of FK20, a random peptide mixture (RPM) composed of L-phenylalanine and L-lysine. FK20 displays potent activity against C. auris and other clinically relevant Candida species, impairs biofilm formation, and exhibits synergy with caspofungin. Importantly, FK20 limits the emergence of resistance and demonstrates therapeutic efficacy in a murine model of systemic candidiasis. These findings establish RPMs as a promising new class of antifungals with broad-spectrum activity and clinical potential against drug-resistant fungal infections.\n\nID: 41943553\nTitle: Mutation, biofilm formation, and cell wall remodeling contribute to echinocandin resistance of Candidozyma auris.\nAbstract: This study systematically elucidates the mechanisms of echinocandin resistance in Candidozyma auris (C. auris), providing insights into potential therapeutic strategies. Echinocandin susceptibility of clinical bloodstream C. auris isolates was determined using E-test, and resistance-associated mutations were identified by Sanger sequencing. Biofilm formation under antifungal stress was assessed by crystal violet staining and the 2,3-bis-(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide (XTT) assays. Changes in cell wall components were analyzed using quantitative fluorescence assays, while expression of cell wall biosynthesis-related genes was evaluated by RT-qPCR. Activation of cell wall integrity (CWI) and calcineurin pathways was examined, and the adjunctive effect of calcineurin inhibitors with anidulafungin (ANI) was assessed using disk diffusion and checkerboard assays. Echinocandin resistance in the clinical isolate C. auris 01 was attributed to an S639F mutation in FKS1. ANI treatment-induced cell aggregation and enhanced biofilm formation. It also triggered cell wall remodeling, increasing chitin, mannan, and \u03b2-glucan levels, accompanied by upregulation of \u03b2-glucan synthase (FKS1, FKS2), chitin synthase (CHS1, CHS3), and mannan synthesis (PMR1, PMT1). Furthermore, ANI activated both CWI and calcineurin pathways, indicating adaptive stress responses. Notably, calcineurin inhibition exhibited an additive effect with ANI. These results highlight a multifaceted resistance framework involving structural, signaling, and potential genetic alterations.\n\nID: 41879325\nTitle: Detecting healthcare-associated transmission and antifungal resistance in Candida auris via whole genome sequencing.\nAbstract: Candida auris is an emerging pathogen known for causing invasive, multidrug-resistant infections and healthcare-associated outbreaks. Measuring the relatedness of C. auris strains is critical for detecting and preventing healthcare-associated transmission. Whole genome sequencing (WGS) and analysis of single-nucleotide polymorphisms (SNPs) offer high-resolution assessments of genetic relatedness and antifungal susceptibility; however, interpretation requires an understanding of inter- and intra-patient C. auris diversity and genotypic markers of resistance, respectively. This study aimed to define SNP thresholds for assessing C. auris relatedness in healthcare-associated outbreak investigations, predict antifungal resistance via genotypic markers, and evaluate patient risk factors to inform future surveillance strategies. WGS was performed on 68 C. auris isolates (clades I and III) obtained from 31 hospitalized patients across a healthcare system between 2021 and 2024. Using MycoSNP analysis, we observed a maximum intra-patient variation of 14 SNPs. Five probable transmission clusters were identified based on epidemiologic links, with patient isolates differing by a median of 5 SNPs (range: 0-12). Analysis with a commercial pipeline (refMLST, BugSeq) showed similar clustering patterns. All new detections occurring more than 1 month after admission were linked to a cluster, representing a highly specific indicator of healthcare-associated infection. WGS detected known genotypic markers for fluconazole (ERG11 Y132F, F126L, and MRR1 N647T) and micafungin (FKS1 F635C) resistance, with the latter emerging during antimicrobial therapy. In addition, putative FUR1 mutations (G207R and Q16::STOP) associated with flucytosine resistance were identified. These findings emphasize the utility of WGS for identifying healthcare-associated clusters of C. auris and predicting antifungal resistance.IMPORTANCECandida auris is a difficult-to-treat yeast that causes invasive infections in vulnerable patient populations. Healthcare exposure is a key risk factor for becoming colonized or infected with C. auris, and infection prevention groups focus on curbing the spread of this organism within the healthcare environment. Whole genome sequencing approaches are key for supporting these efforts, as they can help define clusters of C. auris transmission and can also provide insight into antifungal resistance. Our work provides practical guidance for interpreting genomic data in this setting, helping infection prevention teams respond more effectively to outbreaks and expanding the use of genotypic predictions for antifungal resistance.\n\nID: 41875028\nTitle: Understanding Candidozyma (Candida) auris: genomic evolution, antifungal resistance and the growing challenges in global infection control.\nAbstract: Candida auris (recently renamed Candidozyma auris) is an emerging multidrug-resistant fungal pathogen, first identified in Japan in 2009. C. auris exhibits remarkable persistence on human skin and inanimate surfaces, resistance to multiple antifungals, notably fluconazole, and biofilm formation, which hinders infection control and leads to hospital outbreaks with high mortality rates. Despite ongoing research, key aspects of its reservoir origin, transmission routes and the best way to combat its spread and multidrug resistance remain unclear. Improving genomic surveillance and antifungal strategies is crucial to contain its spread and mitigate the growing public health threat posed by this resilient and potentially fatal fungal pathogen.\n\nID: 41863801\nTitle: Phagocytic podosomes enable efficient uptake of Candida auris by primary human macrophages.\nAbstract: The yeast Candida auris is an emerging pathogen. Understanding the molecular mechanisms of its uptake and processing by immune cells is thus critical for counteracting the spread of respective infections. We show that the phagocytosis of C. auris cells by primary human macrophages involves the formation of dot-like F-actin-rich structures at C. auris-containing phagosomes that we characterize as phagocytic podosomes. We analyze the composition, architecture, and dynamics of these structures, showing that they constitute a specific adaptation of the phagocytic actin network. The disruption of phagocytic podosomes is associated with reduced internalization of C. auris and delayed phagosomal maturation. Our data provide detailed insights into cytoskeletal rearrangements upon internalization of Candida by immune cells while also demonstrating that the actin network within phagocytic cups is not necessarily uniform and continuous. At the same time, we identify C. auris as a pathophysiologically relevant target whose internalization involves the formation of phagocytic podosomes.\n\nID: 41853952\nTitle: Biocide Response of Candida auris.\nAbstract: Candida auris is an emerging multidrug-resistant yeast demonstrating remarkable persistence in healthcare environments, contributing to nosocomial transmission and outbreak persistence. Increasing disinfectant failure reports have raised concerns regarding infection control policies, as environmental reservoirs play central roles in its spread. We reviewed experimental studies, environmental surveillance reports, and comparative disinfection efficacy data to summarise interactions between C. auris and commonly used biocidal classes: chlorine-based oxidizers, alcohol formulations, biguanides, and quaternary ammonium compounds. Mechanistic findings on biofilm formation, efflux activity, and stress-response pathways were integrated to contextualise tolerance behaviour. Evidence indicates C. auris shows reduced susceptibility to quaternary ammonium compounds and demonstrates variable, strain-dependent tolerance to alcohol-based disinfectants, particularly with organic load or suboptimal contact times. Chlorine-based oxidising agents maintain reliable activity at appropriate concentrations and exposure durations. Biofilm formation enhances environmental persistence and diminishes surface decontamination efficiency. C. auris requires disinfectant strategies distinct from other Candida species. Effective infection prevention depends on optimised agent selection, adequate contact times, and consideration of surface and organic-matter conditions. Tailored decontamination protocols are essential to limit environmental persistence and interrupt nosocomial transmission.\n\nID: 41823412\nTitle: Candida auris metabolism and growth preferences in physiologically relevant skin-like conditions.\nAbstract: Candida auris is an opportunistic, multidrug-resistant yeast with a high capacity for human skin colonization in healthcare settings, which can lead to subsequent infections with high mortality rates. Despite the recent emergence of at least four distinct clades at the global scale, little remains known about how C. auris is so adept at growing on skin and the key genes and pathways it utilizes to metabolize the scarce nutrients available. Here, we identify the roles that conventional and alternative carbon metabolism genes and metabolic pathways have in facilitating C. auris growth through laboratory-based experiments and bioinformatics analyses. In artificial skin-like media, all four clades of C. auris were more capable of growing than Candida albicans SC5314, a clinically relevant counterpart. By investigating the differential regulation of C. auris when growing in skin-like media as compared to rich fungal media, we uncovered hundreds of genes in multiple metabolic pathways. To further test the mechanisms of these metabolic pathways, we deleted several non-essential gene candidates including FOX2 (B9J08_002847), CAT2 (B9J08_000010), and ICL1 (B9J08_003374). The mutant strains all exhibited abrogated growth in skin-like media and demonstrated nutrient preferences that differed from the wild type. Thus, we propose a model of how C. auris has the capacity to metabolize nutrients that are available on skin by optimizing its metabolic profile. Targeting these metabolic pathways to mitigate C. auris growth on skin is a potential avenue to explore in controlling the spread of this emerging human fungal pathogen. Candida auris is an emerging fungal pathogen with human skin as its primary site of colonization and subsequent transmission. Here, we show the importance of conventional and alternative carbon metabolism for the ability of C. auris to grow in artificial skin-like media. This knowledge provides a better understanding of C. auris metabolism and sheds light on genes and pathways that could be targeted to interfere with persistent skin colonization.\n\nID: 41821213\nTitle: Comprehensive Review of Candidozyma (Candida) auris Management: Insights From the Society of Infectious Diseases Pharmacists.\nAbstract: Candidozyma (Candida) auris has emerged over the past two decades as a formidable global health threat due to its multidrug resistance, persistence in healthcare environments, and rapid nosocomial spread. Recently reclassified into the genus Candidozyma based on phylogenomic analysis, C. auris poses major challenges for both clinical management and infection control. Its ability to tolerate heat, salinity, and disinfectants supports long-term survival on surfaces and medical devices, facilitating transmission. Biofilm formation further enhances virulence and resistance to antifungal therapy. Clinical presentations range from asymptomatic colonization to invasive infections, with mortality rates approaching 50%. Echinocandins remain an important first-line treatment option, but their fungistatic activity, limited tissue penetration, and emerging resistance contribute to suboptimal outcomes, highlighting the need for new agents and optimized dosing strategies. The role of triazoles and amphotericin B is significantly limited by resistance and associated toxicities, while newer agents such as ibrexafungerp, fosmanogepix, and rezafungin show promising in\u00a0vitro activity but lack substantial supporting clinical data. Combination therapy may also offer potential benefit, though supporting evidence is sparse. Infection control methods including active surveillance, contact precautions, and environmental disinfection with sporicidal agents and avoidance of ineffective quaternary ammonium compounds are key to preventing the nosocomial spread of C. auris. Despite growing awareness, effective decolonization strategies are lacking, and recurrence and transmission continue to pose challenges. Ongoing efforts to refine antifungal therapy, improve rapid diagnostics, and strengthen infection control practices are essential to mitigating the spread of this pathogen and optimizing outcomes for patients.\n\nID: 41817193\nTitle: Synergistic activity of caspofungin and posaconazole against Candida (Candidozyma) auris biofilms based on phenotypic, transcriptomic, and in vivo insights.\nAbstract: Candida (Candidozyma) auris is an emerging multidrug-resistant fungal pathogen capable of establishing persistent skin colonization, contaminating the environment, and causing nosocomial outbreaks associated with high mortality rates. Conventional monotherapy frequently proves inadequate against biofilm-associated infections, underscoring the urgent need for novel therapeutic strategies. Therefore, we investigated the physiological and molecular responses of South Asian clade C. auris biofilms to treatment with a caspofungin-posaconazole combination. This regimen markedly reduced the median minimum inhibitory concentrations (4- to 32-fold for caspofungin; 8- to 64-fold for posaconazole) compared with monotherapies. Synergistic interactions were observed in all isolates, with fractional inhibitory concentration indices ranging from 0.078 to 0.31, and were further confirmed in vivo. Transcriptomic profiling revealed activation of multiple stress-response pathways, driving adaptive changes such as enhanced extracellular matrix production and biofilm-forming capacity, maintenance of intracellular cation homeostasis, osmotic stress response, and extensive cell wall and membrane remodeling affecting the mannan-glucan complex, chitin, sphingolipids, phosphatidylinositol-(4,5)-bisphosphate, and ergosterol content. Additional responses included activation of RCT1 (fluconazole-inducible protein) and MDR1 (drug efflux pump), collectively promoting survival under combined antifungal pressure. These findings demonstrate the potent synergistic activity of caspofungin and posaconazole against C. auris biofilms, thereby supporting the development of effective combination therapies for this high-risk pathogen.IMPORTANCECandida auris is a rapidly emerging fungal pathogen that presents substantial challenges for infection control owing to its multidrug resistance, persistence in healthcare environments, and capacity to cause large-scale outbreaks. Biofilm formation on indwelling medical devices plays a pivotal role in C. auris outbreaks within healthcare settings and is implicated in nearly 90% of C. auris candidemia cases. These biofilms also exhibit pronounced tolerance to antifungal agents, thereby restricting available treatment options. Our study demonstrates that the combination of caspofungin and posaconazole exerts a strong synergistic effect against C. auris biofilms, both in vitro and in vivo. By elucidating the molecular mechanisms behind this synergy-including stress-response activation, cell wall and membrane remodeling, calcium signaling, and regulation of drug efflux pumps-this work provides important insights into antifungal therapeutic responses in C. auris and underscores combination therapy as a promising strategy to overcome biofilm-associated antifungal resistance in this high-risk pathogen.\n\nID: 41809987\nTitle: CLEC3A-derived peptides exhibit broad-spectrum activity against Candida auris and clinically relevant pathogens.\nAbstract: Antimicrobial resistance in bacterial and fungal pathogens poses a major threat to global health, with Candida auris recently classified by the WHO as a critical priority pathogen. Antimicrobial peptides (AMPs) have emerged as promising candidates due to their broad-spectrum activity and membrane-disruptive mechanisms. In this study, the antibacterial and antifungal efficacy of two CLEC3A-derived peptides, HT-47 and WRK-30, was evaluated in comparison to the reference AMP LL-37 and the drugs amphotericin B and penicillin/streptomycin using viable count assays, biofilm assays, and scanning and transmission electron microscopy. HT-47 and WRK-30 showed antibacterial activity against the ESKAPE pathogens K. pneumoniae and A. baumannii, as well as antifungal effects against C. albicans, C. neoformans, and particularly C. auris, with MIC50 values comparable to or lower than amphotericin B. Both peptides significantly inhibited more potent C. auris biofilm formation, compared to amphotericin B. SEM and TEM revealed extensive membrane and subcellular damage in peptide-treated fungal cells. CLEC3A-derived peptides HT-47 and WRK-30 exhibit potent and comparable antibacterial and antifungal activity, highlighting their potential as therapeutic candidates for combating multidrug-resistant pathogens, including C. auris.\n\nID: 41763301\nTitle: Environmental continuum of Candidozyma auris: From sapronotic ecology to outbreak prediction and control with a One Health perspective.\nAbstract: Candidozyma auris (formerly Candida auris) has emerged within just over a decade as one of the most relevant multidrug-resistant fungal pathogens affecting human health worldwide. Its pathogenicity, capacity for skin colonization, environmental persistence, and resistance to antifungal drugs and disinfectants have all contributed to its consolidation as a leading cause of healthcare-associated outbreaks. Nevertheless, increasing evidence indicates that C. auris should not be viewed solely as a nosocomial yeast, but rather as part of a broader environmental continuum encompassing natural habitats, anthropogenic niches, and multiple host species. Environmental isolates have been documented in coastal wetlands, wastewater systems, agricultural products, as well as in diverse animals - including companion animals, reptiles, amphibians, and insects - supporting its classification as a sapronotic pathogen. The near-simultaneous emergence of distinct clades across continents strongly suggests that climate change, agricultural azole exposure, and ecological adaptation have collectively selected strains exhibiting thermotolerance, antifungal resistance, and cross-kingdom persistence, thereby enabling recurrent spillover into human populations. Recent advances in wastewater-based epidemiology demonstrate that C. auris can be detected at the community level, often preceding clinical recognition, while animal colonization underscores its overlooked role in pathogen maintenance and transmission networks. This review synthesizes current evidence on the ecological, evolutionary, and epidemiological determinants of C. auris, positioning outbreaks as amplification phenomena within interconnected ecological systems rather than isolated nosocomial events. Adoption of a One Health framework, integrating environmental, veterinary, and human health surveillance, will be essential for predictive outbreak modeling, early detection, and the development of sustainable strategies to mitigate the ongoing and future threats posed by this emerging fungal pathogen.\n\nID: 41754774\nTitle: Unmasking the Fungicidal Potency and Multifaceted Mechanisms of Nutmeg Essential Oil Against Candida auris.\nAbstract: Background: Candida auris has emerged as a multidrug-resistant fungal pathogen, presenting significant clinical challenges worldwide. Although considerable progress has been made in antifungal research, the specific mechanisms underlying drug resistance in C. auris remain incompletely understood. To overcome this problem, natural compounds can be used as valuable alternatives. The present study aimed to evaluate the antifungal activity of NEO against C. auris and to understand the functional mechanisms underlying its antifungal activity. Methods: The antifungal activity of NEO against C. auris strain CBS10913T was examined using broth microdilution and spot assays to determine the minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC). Mechanistic investigations were performed using phenotypic-, biochemical-, and fluorescence-based assays to evaluate its effects on cell wall integrity, membrane permeability, efflux pump activity, oxidative stress, lipid peroxidation, biofilm formation, and host cell adherence. Hemolytic assays were performed to evaluate preliminary biocompatibility. Results: During our study, we found that NEO showed strong fungicidal activity against C. auris, with an MIC of 500 \u00b5g/mL and an MFC of 650 \u00b5g/mL, and disrupted fungal cell wall integrity, significantly reduced ergosterol content, and inhibited efflux pump activity, leading to increased accumulation of fluorescent substrates. NEO induced increased intracellular reactive oxygen species, leading to oxidative-mediated lipid peroxidation and DNA damage. Moreover, NEO also suppressed stress biofilm formation, reduced metabolic activity, and decreased adherence to buccal epithelial cells, and it showed negligible hemolytic activity up to 2\u00d7 MIC, indicating preliminary biocompatibility. Conclusions: This study demonstrates that NEO utilizes broad antifungal activity through multiple functional and phenotypic mechanisms, including disruption of membrane integrity, inhibition of efflux pump, induction of oxidative stress, and suppression of biofilm formation. Although the direct effects on pathogenicity-related genes or proteins were not studied, the findings still show NEO as a promising natural antifungal agent.\n\nID: 42519068\nTitle: Guar gum-quercetin bioconjugate as a promising multifunctional biomaterial for combating drug-resistant fungal pathogens.\nAbstract: The global emergence of Candida auris, a multidrug-resistant fungal pathogen associated with high transmissibility and limited therapeutic options, highlights the need for new antifungal strategies. In this study, we report the synthesis, characterization, and biological evaluation of a guar gum-quercetin bioconjugate designed to improve the practical applicability of quercetin through covalent conjugation with a biocompatible polysaccharide scaffold and a cystamine-based disulfide linker. The formation of the GG-Cys-Quer conjugate was supported by FTIR, 1H/13C NMR, CHNS elemental analysis, degree-of-substitution estimation, SEM, and TGA. The conjugate showed potent antifungal activity against five clinical C. auris isolates, with MIC and MFC values ranging from 0.030 to 0.245 \u00b5g mL-1 and 0.123 to 0.488 \u00b5g mL-1, respectively. Against the resistant isolate MRL6057, GG-Cys-Quer showed an MIC of 0.245 \u00b5g mL-1, whereas caspofungin showed an MIC of 4.0 \u00b5g mL-1 under the same assay conditions. Mechanistic studies showed increased intracellular ROS accumulation, loss of mitochondrial membrane potential, and apoptosis-associated changes, as confirmed by Annexin V/PI staining, with a concentration-dependent increase in late apoptotic/necrotic cell populations at higher exposure levels. Ultrastructural analysis further revealed membrane deformation, pore formation, and cellular collapse, supporting severe fungal cell damage following treatment. In mammalian L929 fibroblasts, GG-Cys-Quer maintained >85% cell viability at MFC-level exposure, indicating preliminary in vitro cytocompatibility. Overall, these findings demonstrate that GG-Cys-Quer is a structurally characterized guar gum-quercetin conjugate with strong in vitro antifungal activity against C. auris and a mechanism involving oxidative stress, mitochondrial dysfunction, and apoptosis-associated fungal cell death. Further side-by-side studies with free quercetin, linker controls, guar gum controls, and in vivo models are required to define the specific contribution of conjugation and assess translational potential.\n\nID: 42445483\nTitle: Integrative computational-experimental discovery and translation of antifungal peptides for multidrug-resistant fungi.\nAbstract: Multidrug-resistant fungal infections caused by Candida and Aspergillus species have become one of the major global health concerns, especially among immunocompromised individuals. The small number of antifungals available and the rapid emergence of resistance to azoles, echinocandins and polyenes underscore the urgent need to develop alternative therapeutic strategies with different mechanisms of action. Antifungal peptides (AFPs) have attracted increasing attention as promising candidates due to their broad-spectrum activity, multimodal mechanisms of action, and their low likelihood of resistance development. This review presents a thorough and holistic summary of the research on AFPs that target clinically significant drug-resistant fungi such as Candida auris, azole-resistant Candida albicans, and triazole-resistant Aspergillus fumigatus. We review the structural and physicochemical properties of AFPs and address their various antifungal mechanisms, which include membrane disruption, oxidative stress induction, and disruption of intracellular homeostasis, as well as biofilm inhibition. We further highlight an emerging computational-experimental pipeline to discover and optimize AFPs, combining sequence mining, machine learning-based screening, molecular docking, molecular dynamics simulations, and in vitro and in vivo validation. We also explore the major translational challenges, such as hemolytic toxicity, proteolytic instability, pharmacokinetic constraints, manufacturing complexity, regulatory concerns, and sustainable peptide manufacturing strategies, and discuss advanced delivery systems (e.g., liposomes, PLGA nanoparticles, chitosan-based systems, and hydrogels) to improve therapeutic efficacy and stability. In summary, this review proposes an integrated translational development framework that connects computational design, experimental validation, and delivery engineering, thereby positioning AFPs as a promising next-generation strategy in the fight against multidrug-resistant fungal infections.\n\nID: 42349555\nTitle: Disinfectant efficacy against Candida auris is driven by formulation and concentration rather than clade-specific resistance.\nAbstract: Candidozyma auris (formerly Candida auris) is a multi-drug-resistant pathogen of global concern due to environmental persistence, biofilm formation, and limited treatment options. Disinfectant efficacy is variable, particularly under high organic load, with reports of reduced susceptibility to Candida albicans. The aim of this study was to define the intrinsic chemical susceptibility of Candido auris clades I-IV and assess whether yeasticidal efficacy against Candida albicans predicts activity against Candido auris. Quantitative suspension tests (NEN-EN 13624:2022, dirty conditions) were used to evaluate six disinfectant chemistries: organic acid (lactic acid), halogen (chlorine), quaternary ammonium compounds, alcohol (ethanol), and oxidising agent (hydrogen peroxide). Testing was conducted in two independent laboratories using Candida albicans ATCC 10231 and Candido auris clades (I-IV). All chemistries achieved a \u22654 log10 reduction against Candida albicans and all Candido auris clades at validated conditions, with no consistent clade-dependent differences. Organic acid formulations showed comparable efficacy, highlighting a potential sustainable alternative. Candido auris shows susceptibility comparable with that of Candida albicans. Efficacy is driven by formulation, concentration, and contact time rather than clade variation, supporting formulation-based disinfection strategies for healthcare settings.\n\nID: 42269829\nTitle: Clade-dependent antifungal resistance and susceptibility in Candidozyma auris: A global scoping review.\nAbstract: Candidozyma auris (formerly Candida auris) is an emerging multidrug-resistant fungal pathogen that has spread globally since its first identification in 2009 and is now classified as a critical-priority pathogen by the World Health Organization. Distinct genetic clades are associated with variations in geographic distribution, antifungal susceptibility, and resistance mechanisms; however, clade-specific evidence remains fragmented. To systematically map global evidence on clade diversity, antifungal susceptibility patterns, resistance mechanisms, and clinical implications of C. auris. A scoping review was conducted following PRISMA-ScR guidelines. Peer-reviewed primary studies published between 2009 and September 2025 were included if they reported clade attribution and antifungal susceptibility or resistance data. PubMed/MEDLINE, Scopus, and Web of Science were searched. Two reviewers independently screened studies and extracted data using a standardized form. Of 2050 records identified, 105 studies met inclusion criteria, representing 29 countries and diverse study designs. Whole-genome sequencing was the most common typing method. Antifungal susceptibility varied substantially across clades. High fluconazole resistance was consistently reported (MIC 4 to >256\u03bcg/mL). Echinocandins generally retained activity, although reduced susceptibility associated with FKS1 mutations was observed. Resistance mechanisms primarily involved mutations in ERG11, FKS1, and efflux-related genes. Studies also reported challenges in healthcare-associated transmission, environmental persistence, and diagnostic misidentification. C. auris exhibits marked clade-dependent variability in antifungal susceptibility and resistance mechanisms. These findings support the need for clade-informed interpretation of susceptibility data, standardized surveillance, improved diagnostics, and development of novel antifungal therapies.\n\nID: 42259815\nTitle: The Wor2 phenotypic switching regulator controls biofilm formation in Candida auris.\nAbstract: The emerging fungal pathogen Candida auris is a serious global public health threat due to its ability to persist in healthcare environments and on human skin. Here, we report a prevalent cluster of clinical C. auris strains with enhanced biofilm formation, a contributor to environmental and skin persistence. Genomic analyses show that the clinical isolates with enhanced biofilm formation ability carry a loss-of-function mutation in the WOR2 locus, which encodes a white-opaque switching regulator in Candida species. Analysis of 13,314 published genomes revealed that 3104 strains (23.3%) harbor nonsense or frameshift mutations in WOR2, indicating frequent clinical occurrence. Deletion of WOR2 in a clinical strain markedly increased biofilm formation, whereas reintroduction of an intact WOR2 significantly attenuated biofilm development. Further analyses show that Wor2 inactivation upregulates GFC1, ALS4, and multiple biofilm-associated genes. Together, these findings reveal a key regulatory mechanism underlying biofilm development, environmental persistence, and transmission of C. auris.\n\nID: 42037912\nTitle: Impact of Infection Control Interventions on Candida auris at a Tertiary Care Center in Bahrain: A Five-Year Experience.\nAbstract: Introduction\u00a0 Candida auris (C. auris) is a multidrug-resistant fungal pathogen associated with high morbidity, environmental persistence, and rapid transmission in healthcare settings. This study evaluated the impact of a comprehensive infection-control intervention on hospital-acquired C. auris cases by comparing two post-implementation periods, phase I (2021-2022) and phase II (2023-2025), to assess the intervention's performance over time. Methods\u00a0 A retrospective analysis was conducted on 323 patients diagnosed with C. auris between 2021 and 2025. Infection-control measures were initiated at the end of 2021 as part of the institutional response to the detection of the initial cases and were consistently maintained until the end of the study. Chi-square tests were applied to compare demographic and clinical characteristics across the two periods. Results The majority of patients with C. auris were male (65.3%), and more than half (51.4%) were over 65 years of age. Demographic and clinical characteristics were similar between the two periods. However, the proportion of patients with documented contact with a C. auris-positive individual significantly decreased over time, from 56.9% in phase I (2021-2022) to 40.8% in phase II (2023-2025) (p = 0.004). Monthly hospital-acquired C. auris cases decreased from 6 cases per month in phase I to 5 cases per month in phase II, representing a 16.7% reduction; however, this difference was not statistically significant (p = 0.41). Conclusion\u00a0 The multidisciplinary infection-control intervention significantly reduced contact-associated transmission and hospital-acquired C. auris cases. The results show that multidisciplinary collaboration, improved screening, and enhanced environmental cleaning and disinfection all help control C. auris in high-risk healthcare settings.\n\nID: 42017651\nTitle: Global emergence and rapid spread of Candidozyma auris (syn. Candida auris): epidemiology, biology, and antifungal resistance.\nAbstract: SUMMARYThe emerging fungal pathogen Candidozyma auris (syn. Candida auris; C. auris) has attracted considerable attention from the scientific, clinical, and public health communities due to its multidrug resistance, environmental persistence, and high transmissibility. Since its first description in Japan in 2009, C. auris has spread rapidly worldwide, with a marked acceleration following the coronavirus disease 2019 (COVID-19) pandemic. As of December 2025, 84,941 colonization or infection cases have been reported across 82 countries spanning 6 continents. In this review, we summarize the current knowledge of the biology and global epidemiology of C. auris. We first examine its taxonomy, proposed origins, and key biological, genetic, and phenotypic characteristics, with particular emphasis on factors underlying environmental persistence, transmission dynamics, antifungal resistance, and virulence. Drawing on published literature and publicly available surveillance data from national public health authorities worldwide, we provide an updated overview of the global epidemiological landscape and evolving transmission patterns of C. auris. Finally, we discuss potential strategies to mitigate the continued and escalating global spread of this emerging multidrug-resistant fungal pathogen.\n\nID: 41958251\nTitle: [Candidozyma auris : an emerging fungal pathogen with epidemic potential].\nAbstract: Candidozyma auris, formerly Candida auris, is an emerging yeast that is now recognized as a major healthcare-associated pathogen worldwide. Its near-simultaneous emergence across multiple continents over the past decade, its high capacity to colonize skin, its prolonged environmental persistence, and its multidrug resistance to antifungal agents underscore its clinical and epidemiological significance. In Switzerland, the first case was documented in 2017. Since then, imported cases have been reported sporadically each year, almost exclusively among patients who were previously hospitalized in regions with high endemicity. This article presents the current epidemiological data and key issues related to infection prevention and control, and highlights the importance of implementing national recommendations.

This study aimed to evaluate the epidemiological characteristics, risk factors, identification methods, antifungal susceptibility profiles, and infection control measures associated with C. auris cases detected over a four-month period (October 2024-January 2025). Clinical, screening and environmental samples were analyzed. Clinical samples consisted of blood cultures, while screening samples included axillary swabs. Isolate identification was performed using VITEK 2 YST, the BD Phoenix system V7.51A, and VITEK MS PRIME. Antifungal susceptibility testing was performed using the Sensititre\u2122\u0e0f YeastOne YO10 system. A total of 14 clinical cases were identified, along with two environmental isolates and four axillary screening isolates, one of which was associated with a clinical case. The mean age of clinical cases was 64.8 years (SD 29.2; range 15-95), and the mortality rate was 71.4%. According to the Centers for Disease Control and Prevention (CDC) tentative breakpoints, all clinical isolates were resistant to fluconazole. Amphotericin B minimum inhibitory concentration (MIC) values were 2 \u00b5g/mL in 50% of isolates. One isolate showed high MIC values for echinocandins (micafungin and anidulafungin >8 \u00b5g/mL). This study reports the first locally documented cases of C. auris in our center and was conducted as part of an ongoing surveillance program. It highlights the clinical and environmental burden of C. auris, underscores its resistance profile, and emphasizes the critical importance of accurate identification and stringent infection control measures. Although clinical cases have continued to occur at a decreasing frequency, no further C. auris has been detected in environmental samples after the implementation of the infection control protocol, suggesting sustained effectiveness in limiting environmental contamination.\n\nID: 41925335\nTitle: Protein-related hydrophobicity differences among strains belonging to Candidozyma auris (Candida auris) clades.\nAbstract: In recent years, Candidozyma auris (Candida auris) has emerged as a threat to human health due to its combination of virulence and antifungal resistance. This fungal pathogen is notable for its thermotolerance and a strong attachment capability that confers environmental persistence and immune evasion. Here, we compared strains from five clades of C. auris: clade I = South Asia (CDC 387), clade II = East Asia (CDC 381), clade III = Africa (CDC 384), clade IV = South America (CDC 385), and clade V = Iran (CDC 1097) for their ability to regulate cell surface hydrophobicity and biofilm. The hydrophobicity varied for each C. auris clade, with strains 384, 385, and 1097 displaying the highest hydrophobicity levels. C. auris strains had variable biofilm levels when compared among clades and had lower or similar biofilm levels when compared with Candida albicans at different temperatures. Comparison of mass spectrometry analysis of proteolytic digestates of cells from strains with low or high hydrophobicity revealed putative surface hydrophobic proteins. These included homologs to Candida albicans Als3 and IFF proteins, and their contribution to hydrophobicity and biofilm formation was confirmed with gene-deficient (knockout) C. auris strains. We conclude that several proteins contribute to C. auris surface hydrophobicity. Candidozyma auris (Candida auris) is an emerging pathogenic microorganism that is rapidly gaining attention due to outbreaks in health care facilities and its multidrug resistance. Its origin has yet to be determined, but genotypic analyses have pointed toward a simultaneous independent emergence of the different clades, possibly implicating climate change as a major factor in its recent appearance as a fungal pathogen. In 2022, the World Health Organization placed C. auris in the critical priority group as the second greatest fungal threat globally. Due to limited immunological and proteomic studies of C. auris, we sought to elucidate possible virulence mechanisms and identify leading proteins that can be targeted by immunotherapies and new drugs. Using proteomic analysis, we identified 12 lead proteins related to C. auris hydrophobicity and adhesion, implying that these properties are conferred by multiple proteins.\n\nID: 41922787\nTitle: Characterization and Antifungal Activity of Essential oil of Cymbopogon citratus: Special Emphasis on Preliminary Fungicidal Mechanisms against Candida auris and Cryptococcus neoformans.\nAbstract: In 2022, the World Health Organization published a list highlighting Candida auris and Cryptococcus neoformans as among the priority pathogens in need of new therapeutic alternatives. The essential oil of Cymbopogon citratus (EOCC) is used in folk medicine for its various properties, including antimicrobial activity. However, there are few reports of its activity against these yeasts and the possible action mechanism. EOCC was characterized by gas chromatography combined with mass spectrometry. Antifungal activity was determined by broth microdilution against C. parapsilosis ATCC 22,019, C. krusei ATCC 6258, C. auris 01256P, fluconazole-resistant C. albicans and C. neoformans strains. The possible mechanism of action of EOCC against C. auris and C. neoformans was investigated by flow cytometry and the alkaline comet assay. EOCC contained as major chemical compounds \u03b2-pinene (4.50%), neral (32.80%), geraniol (8.13%) and geranial (41.29%). EOCC had minimum inhibitory concentration (MIC50) of 32 to 256\u00a0\u00b5g/mL against Candida spp. and 32 to 128\u00a0\u00b5g/mL against C. neoformans. The antifungal effects of EOCC may be related to the high presence of neral and geranial detected in its phytochemical composition. The mechanism of action appeared to be related to mitochondrial dysfunction, an increase in reactive oxygen species and damage to fungal DNA, leading to apoptosis-like cell death.\n\nID: 41894321\nTitle: Host-Candida auris interactions in the skin.\nAbstract: Candida auris is an emerging, multidrug-resistant fungal pathogen that causes healthcare-associated outbreaks and life-threatening systemic infections. Unlike other Candida species, C. auris exhibits a distinct capacity for persistent skin colonization. In this review, we summarize our current understanding of clinical risk factors and host-microbe interactions that underlie C. auris skin colonization and infection. We discuss fungal determinants, including the unique mannan outer layer, fungal adhesins, the protein kinase Hog1, and other pathways in C. auris that govern adaptation in the skin. Furthermore, we highlight host immune mechanisms, including cytokine mediators (IL-1Ra, IL-17) and innate immune cells (neutrophils, macrophages, innate lymphocytes), that shape the outcome of C. auris skin colonization and infection. We also discuss how excessive IFN-\u03b3 responses drive epithelial pathology at the cutaneous barrier and enhance fungal persistence. Finally, we outline emerging research directions to understand host and microbe factors governing long-term colonization, with implications for developing novel therapeutic and vaccine strategies against this skin-tropic, multidrug-resistant fungal pathogen.\n\nID: 41855924\nTitle: Lippia sidoides essential oil against Candida auris and Candida albicans - A promising strategy for antifungal activity in the context of oral candidiasis.\nAbstract: The emergence of multidrug-resistant Candida highlights a pressing threat to global public health. To evaluate in vitro the antifungal activity, mechanism of action, drug association, and anti-biofilm effect of the essential oil of Lippia sidoides Cham. (EO-LS) against Candida albicans and Candida auris. EO-LS was extracted, and its chemical profile was determined by GC-MS. Assays were performed to determine the Minimum Inhibitory Concentration (MIC), Minimum Fungicidal Concentration (MFC), mechanism of action, drug interaction with nystatin and ketoconazole, time-kill kinetics, and biofilm inhibition by confocal microscopy. The compound exhibited fungicidal activity, with MIC and MFC values of 125\u202f\u00b5g/mL against C. albicans and 62.5\u202f\u00b5g/mL against C. auris. The exogenous ergosterol assay indicated that EO-LS exerts antifungal activity by interfering with fungal plasma membrane functions. The combination of EO-LS with ketoconazole demonstrated pharmacological synergism, while its combination with nystatin resulted in an antagonistic effect. EO-LS significantly inhibited fungal growth (p\u202f<\u202f0.005) and promoted a marked reduction of mature C. auris biofilm at a concentration of 125\u202f\u00b5g/mL (p\u202f<\u202f0.0001), as confirmed by confocal microscopy imaging. The essential oil of Lippia sidoides exhibits antifungal activity against Candida spp., including C. auris, likely through an action on the cell membrane, and shows potential as an anti-biofilm agent with pharmacological synergism when combined with ketoconazole.\n\nID: 42063979\nTitle: Test Performance and Clinical Utility of the Cobas Eplex Blood Culture Identification Fungal Pathogen Panel.\nAbstract: Identifying fungi to the genus or species level provides valuable insight for guiding antifungal therapy. We evaluated the performance and clinical utility of the Roche cobas eplex blood culture identification fungal pathogen panel (BCID-FP). Although used in fewer than 1% of patients with blood cultures drawn, BCID-FP identified fungal pathogens in more than 96% of tested samples within 72\u2005hours. Over a 3-year period, BCID-FP demonstrated a positive percent agreement (PPA) of 91.7% compared to culture (n = 327). PPA was 100% for Candida auris, Candida kefyr, Candida krusei, Candida tropicalis, Candida parapsilosis, and Candida neoformans; slightly lower for Candida albicans (90.3%) and Candida glabrata (91.1%); and lowest for Candida lusitaniae (55.6%) and Fusarium spp. (0%). To assess clinical impact, we compared patient records from preimplementation (results withheld from providers; n = 31) and postimplementation (results released; n = 68). Compared to the T2Dx Candida panel, BCID-FP showed superior accuracy (PPA 98.0% vs 61.7%). It also reduced time to fungal identification by 1.36 days relative to culture (P < .0001). Postimplementation, there was also a significant increase in infectious disease physician recommendations for antifungal deescalation (39.7% vs 16.1%; P = .0219), typically shifting from micafungin to fluconazole in C. albicans and C. parapsilosis cases. However, no significant differences were observed in time to antifungal optimization, empiric therapy duration, length of stay, or mortality. Although BCID-FP offers clear diagnostic advantages, timely implementation of expert recommendations remains essential to improving outcomes.\n\nID: 41944852\nTitle: Candida auris: a multidimensional focus on its identification, epidemiology, pathogenesis, and therapeutic options.\nAbstract: Humans have encountered many epidemics caused by pathogenic microorganisms since the turn of the century. The prevalence of fungal infections has significantly increased on a global scale, adversely impacting human health. Candida species remain among the most prevalent and widely spread opportunistic fungi, with Candida auris emerging as a notorious hospital-acquired pathogen. This fungal pathogen causes nosocomial bloodstream infections (BSI), coupled with a high in-hospital death rate and significant multidrug-resistance (MDR). Standard quaternary ammonium compounds (Quats), are often ineffective, requiring the use of Environmental Protection Agency (EPA)-registered hospital-grade disinfectants. Routine laboratory procedures often fail to efficiently identify the fungi, making it difficult to predict the infection\u2019s true severity. Hence, molecular-based methods are now considered the gold standard for rapid identification. Despite the availability of approved drugs, their efficacy is questionable due to the emerging drug resistance within the fungal population. The organism appears to acquire drug resistance quickly. While echinocandins remain first-line therapy, the emergence of echinocandin-or pan-resistant cases indicates that treating pan-resistant strains would be particularly tricky, if not unfeasible. This underscores the urgent need for enhanced infection control, improved point-of-care diagnostics, and the development of novel therapeutic strategies. This article highlights the crucial aspects of epidemiology, identification techniques, drug resistance mechanisms, treatments, and challenges associated with C. auris infections. Understanding these interconnected aspects is essential for optimizing clinical management and mitigating the escalating public health crisis posed by this tenacious pathogen.\n\nID: 41664521\nTitle: Evaluating a Flexible Workflow for Candida auris Surveillance on the AltoStar Automation System AM16 with Commercial and In-House Real-Time PCR Assays.\nAbstract: Multidrug-resistant yeast Candida (Candidozyma) auris, responsible for healthcare-associated outbreaks and high mortality, is a major global health threat. Rapid and scalable molecular diagnostics is essential; however, few automated platforms can accommodate both commercial assays and laboratory-developed tests (LDTs). We evaluated the analytical and clinical performance of two real-time PCR assays for C. auris detection using the AltoStar Automation System AM16. One assay was an in-house LDT (targeting the internal transcribed spacer region), while the other was AltoStar C. auris PCR Kit 1.5 (Altona Diagnostics) assay. An integrated workflow, which included automated nucleic acid extraction and PCR setup, was employed. Analytical performance was evaluated in terms of precision, specificity, and limit of detection (LoD) using C. auris Clades I, II, and VI. Clinical accuracy was assessed using a 36-sample panel (surveillance swabs and contrived positives) tested in parallel with the DiaSorin Simplexa C. auris Direct assay (DiaSorin Molecular LLC), with culture as the reference standard. Both assays demonstrated excellent reproducibility, with CVs below 5%, and 100% analytical specificity. The in-house LDT showed greater sensitivity, with LoDs of 25-191 colony-forming units (CFU)/mL (1.56-12 CFU/reaction) versus 52-235 CFU/mL (3.25-15 CFU/reaction) for the Altona assay. Regarding clinical accuracy, the LDT, Altona assay, and DiaSorin assay showed 100% positive and negative agreement with the culture results (Cohen's kappa=1.00). This is the first documented comparison of a commercial assay and an LDT on the AltoStar AM16, demonstrating the platform's flexibility, which can enhance laboratory adaptability and capacity to combat the spread of C. auris, a critical fungal pathogen.\n\nID: 41535388\nTitle: Digital CRISPR-based diagnostics for quantification of Candida auris and resistance mutations.\nAbstract: Candida auris, an increasingly prevalent fungal pathogen, requires both rapid identification and antifungal susceptibility testing to enable proper treatment. This study introduces digital SHERLOCK (dSHERLOCK), a platform that combines CRISPR/Cas nucleic acid detection, single-template quantification and real-time kinetics monitoring. Assays implemented on this platform display excellent sensitivity to C. auris from major clades 1-4, while maintaining specificity when challenged with common environmental and pathogenic fungi. dSHERLOCK detects C. auris within 20\u2009min in minimally processed swab samples and achieves sensitive quantification (1\u2009c.f.u.\u2009\u00b5l-1) within 40\u2009min. To address antifungal susceptibility testing, we develop assays that detect mutations that are commonly associated with azole and echinocandin multidrug resistance. We use machine learning and real-time monitoring of reaction kinetics to achieve highly accurate simultaneous quantification of mutant and wild-type FKS1 SNP alleles in fungal populations with mixed antifungal susceptibility, which would be misdiagnosed as completely susceptible or resistant under standard reaction conditions. Our platform's use of commercially available materials and common laboratory equipment makes C. auris diagnostics widely deployable in global healthcare settings.\n\nID: 40731971\nTitle: Diagnostic Approaches for Candida auris: A Comprehensive Review of Screening, Identification, and Susceptibility Testing.\nAbstract: Candida auris (C. auris) is an emerging multidrug-resistant fungal pathogen recognized by the World Health Organization (WHO) as a critical global health threat. Its rapid transmission, high mortality rate, and frequent misidentification in clinical laboratories present significant challenges for diagnosis and infection control. This review provides a comprehensive overview of current and emerging diagnostic methods for C. auris detection, including culture-based techniques, biochemical assays, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), and molecular diagnostics such as PCR and loop-mediated isothermal amplification (LAMP). We evaluate each method's sensitivity, specificity, turnaround time, and feasibility in clinical and surveillance settings. While culture remains the diagnostic gold standard, it is limited by slow turnaround and phenotypic overlap with related species. Updated biochemical platforms and MALDI-TOF MS with expanded databases have improved identification accuracy. Molecular assays offer rapid, culture-independent detection. Antifungal susceptibility testing (AFST), primarily using broth microdilution, is essential for guiding treatment, although standardized breakpoints remain lacking. This review proposes an integrated diagnostic workflow and discusses key innovations and gaps in current practice. Our findings aim to support clinicians, microbiologists, and public health professionals in improving early detection, containment, and management of C. auris infections.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

In pathogenic fungi, it dynamically governs morphogenesis, stress adaptation, and antifungal drug resistance. Using high-resolution mass spectrometry-based phosphoproteomics, researchers have systematically mapped phosphorylation dynamics in WHO-priority pathogens-Candida albicans, Aspergillus fumigatus, Cryptococcus neoformans, and the multidrug-resistant Candidozyma auris (formerly Candida auris). These studies reveal that thousands of phosphorylation events are coordinately reprogrammed in response to antifungal drug exposure, host-derived oxidative stress, and temperature shifts. Integration of available datasets suggests a \"conserved-core/divergent-output\" organization. Shared kinase hubs like cAMP-PKA, HOG-MAPK and calcineurin are broadly conserved across species. Downstream substrate networks, however, have diverged, producing distinct virulence outputs in each pathogen. Notably, C. auris remains completely uncharacterized at the phosphoproteomic level. This review provides a comprehensive synthesis of the phosphoproteomic landscape across these pathogens, and discusses how phosphoproteomic data are guiding the rational prioritization of kinases and phosphatases as next-generation antifungal drug targets-with direct implications for clinical surveillance and public health.\n  --- END ACTUAL ABSTRACT FOR 42515081 ---\n\n- ERROR: You cited ID: 42370646 for the quote: \"The unfolded protein response regulator HAC1 was selected as a candidate virulence-associated gene for further analysis.\"\n  FACT: Strict Misquote Detected!

However, the molecular mechanisms underlying its virulence remain incompletely understood. In this study, we performed in vivo transcriptome analysis using an immunosuppressed mouse gastrointestinal infection model to identify genes associated with host adaptation and virulence during infection. By comparing fungal transcriptomes obtained from colonization and dissemination sites with those from\u00a0in vitro cultures, we identified genes that were consistently upregulated during infection. Among these genes, the unfolded protein response regulator HAC1 was selected as a candidate virulence-associated gene for further analysis. Reverse transcription PCR and sequencing analyses revealed that\u00a0HAC1 mRNA in C. auris undergoes an unconventional splicing event of 287 bp that is enhanced under endoplasmic reticulum stress conditions. The excised region spans the annotated open reading frame boundary, suggesting that the translated region of\u00a0HAC1 may require re-evaluation. Notably, a proportion of HAC1 transcripts appeared to be spliced even under non-stress conditions, indicating a detectable basal level of the unfolded protein response. Differences in splicing dynamics were also observed among clade strains. Functional analyses demonstrated that deletion of\u00a0HAC1 increased sensitivity to endoplasmic reticulum stress. The HAC1 deletion mutant also exhibited reduced virulence in both Galleria mellonella and immunosuppressed mouse infection models, as evidenced by delayed host mortality and decreased fungal burdens, respectively. These findings indicate that HAC1 contributes to endoplasmic reticulum stress adaptation and survival in the host environment and identify\u00a0HAC1 as a virulence-associated gene in C. auris. Candida auris is an emerging multidrug-resistant fungal pathogen. Using in vivo transcriptome analysis, we identified HAC1 as a regulator of endoplasmic reticulum stress adaptation and virulence in infection models. This study provides new insight into stress-response pathways in C. auris virulence.\n  --- END ACTUAL ABSTRACT FOR 42370646 ---\n\n- ERROR: You cited ID: 42349555 for the quote: \"Candida auris shows susceptibility comparable with that of Candida albicans.

Disinfectant efficacy is variable, particularly under high organic load, with reports of reduced susceptibility to Candida albicans. The aim of this study was to define the intrinsic chemical susceptibility of Candido auris clades I-IV and assess whether yeasticidal efficacy against Candida albicans predicts activity against Candido auris. Quantitative suspension tests (NEN-EN 13624:2022, dirty conditions) were used to evaluate six disinfectant chemistries: organic acid (lactic acid), halogen (chlorine), quaternary ammonium compounds, alcohol (ethanol), and oxidising agent (hydrogen peroxide). Testing was conducted in two independent laboratories using Candida albicans ATCC 10231 and Candido auris clades (I-IV). All chemistries achieved a \u22654 log10 reduction against Candida albicans and all Candido auris clades at validated conditions, with no consistent clade-dependent differences. Organic acid formulations showed comparable efficacy, highlighting a potential sustainable alternative. Candido auris shows susceptibility comparable with that of Candida albicans. Efficacy is driven by formulation, concentration, and contact time rather than clade variation, supporting formulation-based disinfection strategies for healthcare settings.\n  --- END ACTUAL ABSTRACT FOR 42349555 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Whole-genome sequencing revealed clinically relevant mutations in FKS1, as well as changes in genes involved in ergosterol biosynthesis (ERG3), amino acid metabolism, and PKA signaling.\" (Source: 42051239)\n- \"Transcriptomic analysis identified 11 adhesion- and biofilm-associated target genes, among which SCF1 and ALS1 served as pivotal regulators.\" (Source: 42549922)\n- \"Brief (48 h) exposure to sub-MIC TCZ (1 \u03bcg/mL) selected variants (6.9% frequency) with cross-resistance to TCZ and fluconazole\" (Source: 42548818)\n- \"C. auris is an emerging fungal pathogen with unique characteristics that make it challenging to eradicate in healthcare settings once introduced.\" (Source: 42296425)\n- \"Its modified cell wall, characterized by a thicker mannan layer, efficiently masks immunogenic \u03b2-glucan, thereby reducing immunogenicity.\" (Source: 42119224)\n- \"Clade I (South Asian) and Clade IV (South American) represent the highest clinical risk due to hyper-virulence and high rates of multi-drug resistant (MDR) strains.\" (Source: 42348119)\n- \"88.9% of Candida auris cases (24/27) were identified exclusively from groin swabs.\" (Source: 42310987)\n- \"Often C. auris gets misidentified as other species due to its phylogenetic similarity with C. heamulonii.\" (Source: 42545748)\n- \"The mutant strains all exhibited abrogated growth in skin-like media and demonstrated nutrient preferences that differed from the wild type.\" (Source: 41823412)\n- \"Genomic analyses show that the clinical isolates with enhanced biofilm formation ability carry a loss-of-function mutation in the WOR2 locus\" (Source: 42259815)\n- \"We conclude that several proteins contribute to C. auris surface hydrophobicity.\" (Source: 41925335)\n- \"Furthermore, ANI activated both CWI and calcineurin pathways, indicating adaptive stress responses.\" (Source: 41943553)\n- \"C. auris isolates exhibited amino acid substitutions in ERG11, ERG2, ERG4, CIS2, TAC1, and CDR1.\" (Source: 42026471)\n- \"Mechanistic studies showed increased intracellular ROS accumulation, loss of mitochondrial membrane potential, and apoptosis-associated changes\" (Source: 42519068)\n- \"These biofilms often show a much higher tolerance to standard antifungal drugs and can escape the host body's immune defenses.\" (Source: 42229743)\n- \"Environmental isolates have been documented in coastal wetlands, wastewater systems, agricultural products, as well as in diverse animals\" (Source: 41763301)\n- \"Colonisation was concentrated in the urinary tract and inguinal regions, while bedside tables were identified as key environmental reservoirs.\" (Source: 42003753)\n\n\nINSTRUCTION: Study the actual abstracts provided.

Pathogenic mechanisms include biofilm formation, metabolic adaptation to skin, cell wall remodeling, and unique immune evasion strategies, necessitating integrated molecular surveillance and novel therapeutic targeting.\n\n### [INTRODUCTION & JUSTIFICATION]\n*Candida auris* has emerged as a global public health crisis, defined by its rapid nosocomial transmission and multidrug-resistant profile. The organism demonstrates high genomic plasticity across six recognized clades. Adaptation to host environments, particularly the skin, is facilitated by a robust metabolic profile capable of utilizing scarce nutrients in skin-like conditions. Resilience against chemical decontamination and antifungal therapy is multi-factorial, involving efflux pump upregulation (CDR1, MDR1), mutations in target genes like *ERG11* and *FKS1*, and adaptive remodeling of the extracellular matrix. Host immunity is countered by unique cell wall architectures and aggregative growth forms, necessitating a One Health surveillance strategy.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   *Candida auris* colonization shows a distinct predilection for the groin and axillary regions compared to other *Candida* species.\n*   Loss-of-function mutations in the *WOR2* locus are significantly correlated with enhanced biofilm formation capabilities.\n*   *Candida auris* displays unexpected environmental reservoirs, including wastewater and coastal wetlands, suggesting a sapronotic ecology.\n*   While echinocandin resistance is often associated with fitness costs in other fungi, *Candida auris* maintains virulence even after developing resistance mutations.\n*   \"Phagocytic podosomes\" represent a novel actin-rich mechanism utilized by human macrophages for the uptake of *Candida auris*.\n*   Standard diagnostic platforms (VITEK 2, BD Phoenix) frequently suffer from blind spots, resulting in misidentification as *Candida haemulonii* or *Candida famata*.\n*   Environmental disinfectant failure against biofilms is not primarily clade-dependent but driven by formulation and contact time.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Its rapid transmission, high mortality rate, and frequent misidentification in clinical laboratories present significant challenges for diagnosis and infection control. This review provides a comprehensive overview of current and emerging diagnostic methods for C. auris detection, including culture-based techniques, biochemical assays, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), and molecular diagnostics such as PCR and loop-mediated isothermal amplification (LAMP). We evaluate each method's sensitivity, specificity, turnaround time, and feasibility in clinical and surveillance settings. While culture remains the diagnostic gold standard, it is limited by slow turnaround and phenotypic overlap with related species. Updated biochemical platforms and MALDI-TOF MS with expanded databases have improved identification accuracy. Molecular assays offer rapid, culture-independent detection. Antifungal susceptibility testing (AFST), primarily using broth microdilution, is essential for guiding treatment, although standardized breakpoints remain lacking. This review proposes an integrated diagnostic workflow and discusses key innovations and gaps in current practice. Our findings aim to support clinicians, microbiologists, and public health professionals in improving early detection, containment, and management of C. auris infections.",

A key question in C. auris biology is how clinical isolates acquire amphotericin B resistance. Here we demonstrate that a carbonic sensing pathway (CSP) contributes to amphotericin B resistance by modulating mitochondrial energy functions in clinical C. auris isolates. Integrated transcriptomics and proteomics identify the carbonic anhydrase Nce103 and its transcription factors Rca1 and Efg1 as important regulatory components of the CSP. The conversion of CO2 into bicarbonate sustains energy metabolism required for colonization and fitness on human skin and in nutrient-limited microenvironments. We also show that bacterial skin colonizers engage urease to release CO2 that sustains C. auris fitness and skin colonization. These findings highlight therapeutic options to re-sensitize C. auris to antifungal treatments, as well as to prevent skin colonization by blocking the CSP.",

This study introduces digital SHERLOCK (dSHERLOCK), a platform that combines CRISPR/Cas nucleic acid detection, single-template quantification and real-time kinetics monitoring. Assays implemented on this platform display excellent sensitivity to C. auris from major clades 1-4, while maintaining specificity when challenged with common environmental and pathogenic fungi. dSHERLOCK detects C. auris within 20\u2009min in minimally processed swab samples and achieves sensitive quantification (1\u2009c.f.u.\u2009\u00b5l-1) within 40\u2009min. To address antifungal susceptibility testing, we develop assays that detect mutations that are commonly associated with azole and echinocandin multidrug resistance. We use machine learning and real-time monitoring of reaction kinetics to achieve highly accurate simultaneous quantification of mutant and wild-type FKS1 SNP alleles in fungal populations with mixed antifungal susceptibility, which would be misdiagnosed as completely susceptible or resistant under standard reaction conditions. Our platform's use of commercially available materials and common laboratory equipment makes C. auris diagnostics widely deployable in global healthcare settings.",

The aim of this study was to quantify the number of tests in a large clinical microbiology laboratory that may be affected by IVDR. The study was performed in a clinical microbiology laboratory of a large academic hospital in the Netherlands. We calculated proportion of CE-marked tests and laboratory-developed tests (LDTs), and we calculated the number of test results generated by these tests. We found that CE-IVD-labelled tests accounted for 55% (57/104) of the available tests in bacteriology but represented 82.8% (99 521/120 254) of all test results generated in this specialty. Among tests in mycology, 38% (6/16) were LDTs. Most LDTs were PCR assays targeting specific microorganisms, such as Bordetella spp. and Candida auris. In contrast, only 29% (7/24) of parasitology tests had a CE-IVD label, and these accounted for 38.3% (1612/4209) of all test results in this specialty. We showed the potential burden in complying with IVDR 2017/746 in a clinical microbiology laboratory and the need for LDTs in certain setting. The results of this study may initiate informed discussion on a balanced implementation of the IVDR, ensuring compliance while minimizing unnecessary burden for clinical microbiology laboratories and also manufacturers.",

Drug repurposing has emerged as a key strategy, utilizing established pharmaceuticals for indications beyond their original design; notably, haloperidol (HAL) has shown promising antimicrobial potential. In this context, the present study evaluates the activity of haloperidol, both as a monotherapy and in combination with conventional antifungals, against fluconazole-susceptible and fluconazole-resistant Candida spp. clinical strains. Furthermore, we investigate the underlying mechanisms of its antifungal action. Experimental approaches included broth microdilution assays to determine the Minimum Inhibitory Concentration (MIC), checkerboard assays for synergistic analysis, and cellular assessments via flow cytometry and fluorescence microscopy. Haloperidol displayed MIC values between 26.67 and 256\u202f\u03bcg/mL. Synergistic interactions were identified between haloperidol and the azoles fluconazole and itraconazole, alongside a 2.5\u202f% synergy rate with amphotericin B. Additionally, mechanistic assays confirmed that haloperidol induces programmed cell death (apoptosis) in C. albicans and C. auris strains. The oxidative stress caused by haloperidol altered Ca2+ homeostasis, followed by mitochondrial membrane depolarization, reduced ATP production, cytochrome c release into the cytosol and metacaspase activation, reduced viability, phosphatidylserine externalization, promoted fragmentation, damage and methylation of DNA. It also induced expression of genes related to oxidative stress. It reduced mitochondrial depolarization and decreased the reduction of glutathione (GSH), causing morphological alterations. The results suggest the apoptotic pathway as the main antifungal mechanism of haloperidol.",

Rapid and scalable molecular diagnostics is essential; however, few automated platforms can accommodate both commercial assays and laboratory-developed tests (LDTs). We evaluated the analytical and clinical performance of two real-time PCR assays for C. auris detection using the AltoStar Automation System AM16. One assay was an in-house LDT (targeting the internal transcribed spacer region), while the other was AltoStar C. auris PCR Kit 1.5 (Altona Diagnostics) assay. An integrated workflow, which included automated nucleic acid extraction and PCR setup, was employed. Analytical performance was evaluated in terms of precision, specificity, and limit of detection (LoD) using C. auris Clades I, II, and VI. Clinical accuracy was assessed using a 36-sample panel (surveillance swabs and contrived positives) tested in parallel with the DiaSorin Simplexa C. auris Direct assay (DiaSorin Molecular LLC), with culture as the reference standard. Both assays demonstrated excellent reproducibility, with CVs below 5%, and 100% analytical specificity. The in-house LDT showed greater sensitivity, with LoDs of 25-191 colony-forming units (CFU)/mL (1.56-12 CFU/reaction) versus 52-235 CFU/mL (3.25-15 CFU/reaction) for the Altona assay. Regarding clinical accuracy, the LDT, Altona assay, and DiaSorin assay showed 100% positive and negative agreement with the culture results (Cohen's kappa=1.00). This is the first documented comparison of a commercial assay and an LDT on the AltoStar AM16, demonstrating the platform's flexibility, which can enhance laboratory adaptability and capacity to combat the spread of C. auris, a critical fungal pathogen.",

This narrative review, following PRISMA-ScR (Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Narrative Reviews) guidelines, collected evidence from 2020 to 2025 to examine the connection between denture use, systemic comorbidities, and fungal complications in elderly individuals after COVID-19. A total of 21 of 104 studies were included, covering case-control, cross-sectional, cohort, and retrospective studies from India, Europe, the Middle East, and North America.\u00a0Several studies have reported higher rates of oral fungal colonization among denture wearers,with\u00a0Candida albicans\u00a0being the most frequently isolated species, followed by resistant strains such as\u00a0Candida auris. However, these observations are primarily derived from heterogeneous observational studies and should therefore be interpreted as associative rather than causal. COVID-19-related mucormycosis (CAM) was primarily reported as rhino-orbito-cerebral disease, with oral manifestations including palatal necrosis, gingival ulcers, and tooth mobility. Key risk factors identified include diabetes mellitus, corticosteroid therapy, prolonged intensive care unit (ICU) stays, and poor denture hygiene. Mortality related to CAM ranged from 18% to 56%, while candidiasis, though less deadly, significantly affected oral function, nutrition, and overall quality of life. Diagnostic methods included clinical and intraoral examinations, microbiological cultures, imaging techniques, and emerging salivary biomarkers. Treatments included systemic antifungal medications, surgical removal, and prosthesis disinfection, highlighting the important role of prosthodontists in prevention and rehabilitation. Knowledge gaps remain regarding the predictive value of oral lesions for systemic infections, the long-term effects of COVID-19 on the oral microbiome, and the need to standardize denture hygiene protocols.\u00a0This review emphasizes the importance of integrated dental and medical care in reducing morbidity and mortality among denture-wearing older adults recovering from COVID-19, while recognizing that early oral findings may serve as warning indicators rather than definitive predictors of systemic infection.",
        "41703337": "ID: 41703337\nTitle: Candida auris vacuolar calcium pump mediates fluconazole efflux and resistance evolution.\nAbstract: Candida auris is an emerging fungal pathogen notable for its intrinsically high resistance to fluconazole, the most prescribed antifungal drug. However, the genetic regulators underlying fluconazole susceptibility in C. auris remain unclear. Here we performed a pooled screen of piggyBac (PB) transposition mutants and identified significant enrichment of mitochondrial genes whose inactivation reduces fluconazole susceptibility. A genome-wide genetic interaction analysis of a mitochondrial gene deletion mutant, pet309\u0394, suggests that the vacuolar calcium pump homologue CDT1 (Calcium and Drug Transporter 1) is responsible for its reduced fluconazole susceptibility. Fluconazole induces significant upregulation of CDT1 through the calcineurin signalling pathway. Cdt1, beyond its canonical calcium-pumping function, has evolved another function in mediating fluconazole efflux through its fluconazole-induced, calcineurin- and ATP hydrolysis-dependent plasma membrane localization. In addition, Cdt1 accelerates the evolution of fluconazole resistance or tolerance, and its transcript levels are substantially elevated across resistant clinical isolates. Our findings reveal a neofunctionalized role for Cdt1 in mediating fluconazole efflux in C. auris.",
        "41745238": "ID: 41745238\nTitle: Comprehensive Insights into Sugar Transporters of Candidozyma auris and Their Roles in Antifungal Resistance.\nAbstract: In Candida species, including Candidozyma auris (formerly Candida auris), overexpression of efflux pumps is a well-established mechanism of antifungal resistance. However, accumulating evidence indicates that impaired drug import may also significantly contribute to reduced antifungal susceptibility. Sugar importers, historically viewed solely as hexose transporters (HGTs), are now emerging as potential indirect modulators of antifungal uptake. Here, we performed a comprehensive inventory and functional analysis of the HGT family in C. auris to assess its contribution to antifungal import. Phylogenetic analyses revealed that C. auris HGTs are more closely related to those of Candida albicans (C. albicans) than Saccharomyces cerevisiae (S. cerevisiae). All HGT genes showed basal expression, with several significantly downregulated upon fluconazole (FLC) exposure. To establish functional relevance, we generated a mini-library of HGT deletion mutants. Notably, the \u0394hgt13 strain exhibited markedly increased FLC resistance, concomitant with reduced intracellular FLC accumulation and decreased membrane permeability. Consistently, molecular docking and molecular dynamics simulations demonstrated strong and stable interactions between FLC and Hgt13p. Together, these findings implicate Hgt13p as a key determinant of FLC import and membrane permeability, revealing reduced FLC import could also contribute to antifungal resistance in C. auris.",
        "41745273": "ID: 41745273\nTitle: Fatty Acid Profiling Identification Method of Emerging Fungal Pathogen Candidozyma auris (Formally Candida auris).\nAbstract: The species Candidozyma auris (formerly known as Candida auris) can be subdivided into four major and two minor clades. It is considered an emerging multidrug-resistant pathogen that causes invasive outbreaks around the world. Therefore, the accurate identification of this species plays an important role in combating invasion and facilitating pathogenic management. In our study an optional identification method was developed considering the possibility of using cellular fatty acids (FAs) as a taxonomic and diagnostic tool. FAs were recorded in the collected C. auris strains, and the species characteristic components were determined. Within the isolates examined, the clades were also separated in the statistical analysis. Furthermore, FAs from strains belonging to clade I and II have been divided into two distinct clusters. In testing the performance of the method, all identified samples showed good matches with the established C. auris record in the database without misreading. Taken together, cellular fatty acids were investigated as potential discriminatory biomarkers. The results suggest that this approach can distinguish C. auris from related species and provides distinctive fatty acid profiles for the investigated C. auris clades. The present findings revealed the first report on the application of whole cell FA components as taxonomic features in C. auris.",
        "41745298": "ID: 41745298\nTitle: Caspofungin Reshapes the Extracellular Vesicles Metabolome of Candidozyma (Candida) auris, Altering Amino Acid and Nucleotide Metabolism.\nAbstract: Candidozyma auris is an emerging multidrug-resistant fungal pathogen associated with severe invasive infections and high mortality, particularly in healthcare environments. Its rapid global expansion and resistance to multiple antifungal classes pose major challenges to treatment and containment. Extracellular vesicles (EVs) have recently been recognized as important mediators of fungal communication, virulence, and stress adaptation. Here, we examine how caspofungin, a frontline echinocandin, reshapes the EV metabolome of C. auris. Caspofungin exposure drives pronounced remodeling of EV size distributions, yielding a predominance of smaller, more uniform EVs alongside a minor population of larger subtypes. Metabolomic profiling of EVs revealed marked enrichment of metabolites involved in nucleotide salvage and recycling, along with altered amino acid abundances, including increases in amino acids associated with stress responses and redox regulation. These changes are consistent with altered nucleotide turnover and amino acid metabolism under antifungal stress. Importantly, these metabolic alterations reflect caspofungin-induced changes in cellular metabolism that are selectively exported via extracellular vesicles, rather than metabolic activity occurring within the vesicles themselves. Export of these metabolites via EVs may support population-level coordination, biofilm remodeling, and modulation of host immune responses, contributing to echinocandin tolerance. Together, our findings highlight nucleotide- and amino acid-associated metabolic features of EVs as informative readouts of caspofungin exposure and highlight the EV metabolome as a promising source of non-invasive biomarkers for monitoring drug exposure and resistance. This work advances understanding of C. auris adaptation under antifungal stress and reveals new opportunities for therapeutic and diagnostic innovation against this high-priority pathogen.",

Although considerable progress has been made in antifungal research, the specific mechanisms underlying drug resistance in C. auris remain incompletely understood. To overcome this problem, natural compounds can be used as valuable alternatives. The present study aimed to evaluate the antifungal activity of NEO against C. auris and to understand the functional mechanisms underlying its antifungal activity. Methods: The antifungal activity of NEO against C. auris strain CBS10913T was examined using broth microdilution and spot assays to determine the minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC). Mechanistic investigations were performed using phenotypic-, biochemical-, and fluorescence-based assays to evaluate its effects on cell wall integrity, membrane permeability, efflux pump activity, oxidative stress, lipid peroxidation, biofilm formation, and host cell adherence. Hemolytic assays were performed to evaluate preliminary biocompatibility. Results: During our study, we found that NEO showed strong fungicidal activity against C. auris, with an MIC of 500 \u00b5g/mL and an MFC of 650 \u00b5g/mL, and disrupted fungal cell wall integrity, significantly reduced ergosterol content, and inhibited efflux pump activity, leading to increased accumulation of fluorescent substrates. NEO induced increased intracellular reactive oxygen species, leading to oxidative-mediated lipid peroxidation and DNA damage. Moreover, NEO also suppressed stress biofilm formation, reduced metabolic activity, and decreased adherence to buccal epithelial cells, and it showed negligible hemolytic activity up to 2\u00d7 MIC, indicating preliminary biocompatibility. Conclusions: This study demonstrates that NEO utilizes broad antifungal activity through multiple functional and phenotypic mechanisms, including disruption of membrane integrity, inhibition of efflux pump, induction of oxidative stress, and suppression of biofilm formation. Although the direct effects on pathogenicity-related genes or proteins were not studied, the findings still show NEO as a promising natural antifungal agent.",
        "41763301": "ID: 41763301\nTitle: Environmental continuum of Candidozyma auris: From sapronotic ecology to outbreak prediction and control with a One Health perspective.\nAbstract: Candidozyma auris (formerly Candida auris) has emerged within just over a decade as one of the most relevant multidrug-resistant fungal pathogens affecting human health worldwide. Its pathogenicity, capacity for skin colonization, environmental persistence, and resistance to antifungal drugs and disinfectants have all contributed to its consolidation as a leading cause of healthcare-associated outbreaks. Nevertheless, increasing evidence indicates that C. auris should not be viewed solely as a nosocomial yeast, but rather as part of a broader environmental continuum encompassing natural habitats, anthropogenic niches, and multiple host species. Environmental isolates have been documented in coastal wetlands, wastewater systems, agricultural products, as well as in diverse animals - including companion animals, reptiles, amphibians, and insects - supporting its classification as a sapronotic pathogen. The near-simultaneous emergence of distinct clades across continents strongly suggests that climate change, agricultural azole exposure, and ecological adaptation have collectively selected strains exhibiting thermotolerance, antifungal resistance, and cross-kingdom persistence, thereby enabling recurrent spillover into human populations. Recent advances in wastewater-based epidemiology demonstrate that C. auris can be detected at the community level, often preceding clinical recognition, while animal colonization underscores its overlooked role in pathogen maintenance and transmission networks. This review synthesizes current evidence on the ecological, evolutionary, and epidemiological determinants of C. auris, positioning outbreaks as amplification phenomena within interconnected ecological systems rather than isolated nosocomial events. Adoption of a One Health framework, integrating environmental, veterinary, and human health surveillance, will be essential for predictive outbreak modeling, early detection, and the development of sustainable strategies to mitigate the ongoing and future threats posed by this emerging fungal pathogen.",

However, the underlying mechanisms of real-world pathogen-host interactions remain elusive, in part due to the lack of powerful immunocompetent animal models. Here, we report that selected wild-type strains of Drosophila melanogaster can be developed as a promising infection model to recapitulate C. auris systemic infection. The systemic and organ-specific responses to C. auris infection in vivo were evaluated, as well as the corresponding transcriptional profiling. Our findings confirmed that Toll and JAK-STAT signaling pathways mediate antifungal responses in the Drosophila model following C. auris infection. Moreover, we identified certain conserved novel factors required for host-C. auris interactions, highlighting the fly model's potential to reveal subtle immune mechanisms not readily observed in mammalian systems. Taken together, our work demonstrates that wild-type Drosophila offers a robust immunocompetent animal model for further in-depth investigation of dynamic C. auris-host interactions in vivo.",
        "41768734": "ID: 41768734\nTitle: Impact of Metal-Functionalized Fullerenes on the Proliferation of Pathogenic Fungi.\nAbstract: Given the trajectory and prevalence of multidrug-resistant (MDR) organisms like Candida auris, the dearth of available antifungal drugs and the global need for effective therapeutics, the exploration of safe antifungals with broad-spectrum potential and novel antimicrobial mechanisms is imperative for future treatment strategies. Herein, the broad-spectrum potential of previously synthesized silver and copper coordinated chlorine functionalized fullerene nanoparticles (Ag-C60-Cl and Cu-C60-Cl) against two clinically significant fungal pathogens, Candida albicans and C. auris is investigated. The experimental results show enhanced antifungal activity of Ag-C60-Cl compared to Cu-C60-Cl, C60-Cl, and fluconazole. The minimum inhibitory concentrations (MIC) of Ag-C60-Cl and Cu-C60-Cl are 15.62 and 250 \u03bcg/mL, respectively, against C. albicans. Notably, the MIC of the Ag-C60-Cl against C. auris is 3.9 \u03bcg/mL, whereas the MIC of Cu-C60-Cl is 250 \u03bcg/mL. Analysis of fungal growth kinetics shows that Ag-C60-Cl significantly delayed the growth of C. albicans and suppressed the growth of C. auris. Mechanistic studies highlight that Ag-C60-Cl produced higher reactive oxygen species (ROS) and triggered catalase enzymes by acting as oxidants. Additionally, the NPs exhibited physical interactions with yeast cells, indicating a dual mode of action. These findings establish the potential of Ag-C60-Cl as a new and potentially transformative antifungal strategy against two clinically significant pathogens.",

Natural host defence molecules, part of innate immunity and the first line of defence, are evolutionarily conserved. Some pharmaceutical properties undesirable for clinical use led to the rational design of synthetic molecules with constructed peptide arrangements, giving a novel therapeutic avenue. A prior publication showed synthetic peptide RP557 inhibition and killing of fluconazole-sensitive and resistant Candida species isolates, biofilm inhibition, no resistance induction, direct membrane action, negligible mammalian cell toxicity and topical efficacy in a rodent vaginal candidiasis model. These findings highlight the relevance of investigating RP557 activity against other fungal pathogens.Objective. We evaluated the antifungal spectrum of the RP557 against World Health Organization-listed priority fungal pathogens, including endemic and skin fungal pathogens, both alone and in combination with commercial antifungal drugs.Methods. The antifungal spectrum was evaluated by broth dilution vs. clinical isolates, and we present 76 MICs (mcg ml-1) performed according to M27 or M38 CLSI documents, 35 checkerboard interactions with antifungals and 10 minimum fungicidal determinations.Results. Overall impression is robust activity vs. chromoblastomycosis and mycetoma species, Cryptococcus neoformans and Trichophyton spp.; broad MIC ranges within most species, least activity vs. Mucorales and Aspergillus spp.; and some promising drug interactions vs. Sporothrix spp. and Candida auris.Conclusion. Additional efficacy data in vivo is needed. Topical therapy could give local concentrations exceeding MICs, and burn or trauma prophylaxis or treatments are attractive potential targets owing to RP557 panmicrobial properties.",

Antimicrobial peptides (AMPs) have emerged as promising candidates due to their broad-spectrum activity and membrane-disruptive mechanisms. In this study, the antibacterial and antifungal efficacy of two CLEC3A-derived peptides, HT-47 and WRK-30, was evaluated in comparison to the reference AMP LL-37 and the drugs amphotericin B and penicillin/streptomycin using viable count assays, biofilm assays, and scanning and transmission electron microscopy. HT-47 and WRK-30 showed antibacterial activity against the ESKAPE pathogens K. pneumoniae and A. baumannii, as well as antifungal effects against C. albicans, C. neoformans, and particularly C. auris, with MIC50 values comparable to or lower than amphotericin B. Both peptides significantly inhibited more potent C. auris biofilm formation, compared to amphotericin B. SEM and TEM revealed extensive membrane and subcellular damage in peptide-treated fungal cells.

Conventional monotherapy frequently proves inadequate against biofilm-associated infections, underscoring the urgent need for novel therapeutic strategies. Therefore, we investigated the physiological and molecular responses of South Asian clade C. auris biofilms to treatment with a caspofungin-posaconazole combination. This regimen markedly reduced the median minimum inhibitory concentrations (4- to 32-fold for caspofungin; 8- to 64-fold for posaconazole) compared with monotherapies. Synergistic interactions were observed in all isolates, with fractional inhibitory concentration indices ranging from 0.078 to 0.31, and were further confirmed in vivo. Transcriptomic profiling revealed activation of multiple stress-response pathways, driving adaptive changes such as enhanced extracellular matrix production and biofilm-forming capacity, maintenance of intracellular cation homeostasis, osmotic stress response, and extensive cell wall and membrane remodeling affecting the mannan-glucan complex, chitin, sphingolipids, phosphatidylinositol-(4,5)-bisphosphate, and ergosterol content. Additional responses included activation of RCT1 (fluconazole-inducible protein) and MDR1 (drug efflux pump), collectively promoting survival under combined antifungal pressure. These findings demonstrate the potent synergistic activity of caspofungin and posaconazole against C. auris biofilms, thereby supporting the development of effective combination therapies for this high-risk pathogen.IMPORTANCECandida auris is a rapidly emerging fungal pathogen that presents substantial challenges for infection control owing to its multidrug resistance, persistence in healthcare environments, and capacity to cause large-scale outbreaks. Biofilm formation on indwelling medical devices plays a pivotal role in C. auris outbreaks within healthcare settings and is implicated in nearly 90% of C. auris candidemia cases. These biofilms also exhibit pronounced tolerance to antifungal agents, thereby restricting available treatment options. Our study demonstrates that the combination of caspofungin and posaconazole exerts a strong synergistic effect against C. auris biofilms, both in vitro and in vivo. By elucidating the molecular mechanisms behind this synergy-including stress-response activation, cell wall and membrane remodeling, calcium signaling, and regulation of drug efflux pumps-this work provides important insights into antifungal therapeutic responses in C. auris and underscores combination therapy as a promising strategy to overcome biofilm-associated antifungal resistance in this high-risk pathogen.",

Recently reclassified into the genus Candidozyma based on phylogenomic analysis, C. auris poses major challenges for both clinical management and infection control. Its ability to tolerate heat, salinity, and disinfectants supports long-term survival on surfaces and medical devices, facilitating transmission. Biofilm formation further enhances virulence and resistance to antifungal therapy. Clinical presentations range from asymptomatic colonization to invasive infections, with mortality rates approaching 50%. Echinocandins remain an important first-line treatment option, but their fungistatic activity, limited tissue penetration, and emerging resistance contribute to suboptimal outcomes, highlighting the need for new agents and optimized dosing strategies. The role of triazoles and amphotericin B is significantly limited by resistance and associated toxicities, while newer agents such as ibrexafungerp, fosmanogepix, and rezafungin show promising in\u00a0vitro activity but lack substantial supporting clinical data. Combination therapy may also offer potential benefit, though supporting evidence is sparse. Infection control methods including active surveillance, contact precautions, and environmental disinfection with sporicidal agents and avoidance of ineffective quaternary ammonium compounds are key to preventing the nosocomial spread of C. auris. Despite growing awareness, effective decolonization strategies are lacking, and recurrence and transmission continue to pose challenges. Ongoing efforts to refine antifungal therapy, improve rapid diagnostics, and strengthen infection control practices are essential to mitigating the spread of this pathogen and optimizing outcomes for patients.",

Despite the recent emergence of at least four distinct clades at the global scale, little remains known about how C. auris is so adept at growing on skin and the key genes and pathways it utilizes to metabolize the scarce nutrients available. Here, we identify the roles that conventional and alternative carbon metabolism genes and metabolic pathways have in facilitating C. auris growth through laboratory-based experiments and bioinformatics analyses. In artificial skin-like media, all four clades of C. auris were more capable of growing than Candida albicans SC5314, a clinically relevant counterpart. By investigating the differential regulation of C. auris when growing in skin-like media as compared to rich fungal media, we uncovered hundreds of genes in multiple metabolic pathways. To further test the mechanisms of these metabolic pathways, we deleted several non-essential gene candidates including FOX2 (B9J08_002847), CAT2 (B9J08_000010), and ICL1 (B9J08_003374). The mutant strains all exhibited abrogated growth in skin-like media and demonstrated nutrient preferences that differed from the wild type. Thus, we propose a model of how C. auris has the capacity to metabolize nutrients that are available on skin by optimizing its metabolic profile. Targeting these metabolic pathways to mitigate C. auris growth on skin is a potential avenue to explore in controlling the spread of this emerging human fungal pathogen. Candida auris is an emerging fungal pathogen with human skin as its primary site of colonization and subsequent transmission. Here, we show the importance of conventional and alternative carbon metabolism for the ability of C. auris to grow in artificial skin-like media. This knowledge provides a better understanding of C. auris metabolism and sheds light on genes and pathways that could be targeted to interfere with persistent skin colonization.",

This study evaluated the antimicrobial, anti-inflammatory, antioxidant, and anticancer activities of APs and eugenol, both individually and in combination, against multidrug-resistant (MDR) pathogens and HepG2 liver cancer cells. Thirty bacterial and ten Candida isolates were recovered from skin abscesses, with five identified as MDR strains (Staphylococcus haemolyticus, S. aureus, E. coli, Acinetobacter baumannii, and Candida auris), confirmed by 16S rDNA and ITS sequencing. Both APs and eugenol exhibited marked antimicrobial activity, while their combination achieved the strongest inhibition (up to 27.3\u00a0\u00b1\u00a00.4\u00a0mm). C. auris was highly sensitive to APs alone (MIC: 2\u00a0\u00b1\u00a00.2\u00a0\u00b5g/mL). The combination also significantly downregulated IL-6, IL-17, and TNF-\u03b1 levels, and showed potent COX-2 inhibition (0.10\u00a0\u00b1\u00a00.01\u00a0\u00b5g/mL), surpassing celecoxib (0.9\u00a0\u00b1\u00a00.05\u00a0\u00b5g/mL). Antioxidant analysis (DPPH assay) revealed superior radical scavenging by the combination (57.5\u00a0\u00b1\u00a01.3\u00a0% %). Molecular docking confirmed the activity of eugenol, showing favorable binding to DNA gyrase B, sterol demethylase, COX-2, xanthine oxidase, and caspase-3, with the strongest affinity for xanthine oxidase (-5.25\u00a0kcal/mol). In anticancer assays, eugenol induced dose-dependent inhibition of HepG2 cell proliferation, while APs displayed limited cytotoxicity. Notably, the combination reduced cell viability to 3.77\u00a0\u00b1\u00a00.4\u00a0% % at 400\u00a0\u00b5g/mL, consistent with apoptotic changes.

Increasing disinfectant failure reports have raised concerns regarding infection control policies, as environmental reservoirs play central roles in its spread. We reviewed experimental studies, environmental surveillance reports, and comparative disinfection efficacy data to summarise interactions between C. auris and commonly used biocidal classes: chlorine-based oxidizers, alcohol formulations, biguanides, and quaternary ammonium compounds. Mechanistic findings on biofilm formation, efflux activity, and stress-response pathways were integrated to contextualise tolerance behaviour. Evidence indicates C. auris shows reduced susceptibility to quaternary ammonium compounds and demonstrates variable, strain-dependent tolerance to alcohol-based disinfectants, particularly with organic load or suboptimal contact times. Chlorine-based oxidising agents maintain reliable activity at appropriate concentrations and exposure durations. Biofilm formation enhances environmental persistence and diminishes surface decontamination efficiency. C. auris requires disinfectant strategies distinct from other Candida species. Effective infection prevention depends on optimised agent selection, adequate contact times, and consideration of surface and organic-matter conditions. Tailored decontamination protocols are essential to limit environmental persistence and interrupt nosocomial transmission.",

To evaluate in vitro the antifungal activity, mechanism of action, drug association, and anti-biofilm effect of the essential oil of Lippia sidoides Cham. (EO-LS) against Candida albicans and Candida auris. EO-LS was extracted, and its chemical profile was determined by GC-MS. Assays were performed to determine the Minimum Inhibitory Concentration (MIC), Minimum Fungicidal Concentration (MFC), mechanism of action, drug interaction with nystatin and ketoconazole, time-kill kinetics, and biofilm inhibition by confocal microscopy. The compound exhibited fungicidal activity, with MIC and MFC values of 125\u202f\u00b5g/mL against C. albicans and 62.5\u202f\u00b5g/mL against C. auris. The exogenous ergosterol assay indicated that EO-LS exerts antifungal activity by interfering with fungal plasma membrane functions. The combination of EO-LS with ketoconazole demonstrated pharmacological synergism, while its combination with nystatin resulted in an antagonistic effect. EO-LS significantly inhibited fungal growth (p\u202f<\u202f0.005) and promoted a marked reduction of mature C. auris biofilm at a concentration of 125\u202f\u00b5g/mL (p\u202f<\u202f0.0001), as confirmed by confocal microscopy imaging.

Understanding the molecular mechanisms of its uptake and processing by immune cells is thus critical for counteracting the spread of respective infections. We show that the phagocytosis of C. auris cells by primary human macrophages involves the formation of dot-like F-actin-rich structures at C. auris-containing phagosomes that we characterize as phagocytic podosomes. We analyze the composition, architecture, and dynamics of these structures, showing that they constitute a specific adaptation of the phagocytic actin network. The disruption of phagocytic podosomes is associated with reduced internalization of C. auris and delayed phagosomal maturation. Our data provide detailed insights into cytoskeletal rearrangements upon internalization of Candida by immune cells while also demonstrating that the actin network within phagocytic cups is not necessarily uniform and continuous. At the same time, we identify C. auris as a pathophysiologically relevant target whose internalization involves the formation of phagocytic podosomes.",

Measuring the relatedness of C. auris strains is critical for detecting and preventing healthcare-associated transmission. Whole genome sequencing (WGS) and analysis of single-nucleotide polymorphisms (SNPs) offer high-resolution assessments of genetic relatedness and antifungal susceptibility; however, interpretation requires an understanding of inter- and intra-patient C. auris diversity and genotypic markers of resistance, respectively. This study aimed to define SNP thresholds for assessing C. auris relatedness in healthcare-associated outbreak investigations, predict antifungal resistance via genotypic markers, and evaluate patient risk factors to inform future surveillance strategies. WGS was performed on 68 C. auris isolates (clades I and III) obtained from 31 hospitalized patients across a healthcare system between 2021 and 2024. Using MycoSNP analysis, we observed a maximum intra-patient variation of 14 SNPs. Five probable transmission clusters were identified based on epidemiologic links, with patient isolates differing by a median of 5 SNPs (range: 0-12). Analysis with a commercial pipeline (refMLST, BugSeq) showed similar clustering patterns. All new detections occurring more than 1 month after admission were linked to a cluster, representing a highly specific indicator of healthcare-associated infection. WGS detected known genotypic markers for fluconazole (ERG11 Y132F, F126L, and MRR1 N647T) and micafungin (FKS1 F635C) resistance, with the latter emerging during antimicrobial therapy.

Whole genome sequencing approaches are key for supporting these efforts, as they can help define clusters of C. auris transmission and can also provide insight into antifungal resistance. Our work provides practical guidance for interpreting genomic data in this setting, helping infection prevention teams respond more effectively to outbreaks and expanding the use of genotypic predictions for antifungal resistance.",

It is becoming a major global public health concern due to its ability to resist multiple antifungal drugs and spread in healthcare settings. Despite this, little is known about the mechanisms underlying drug resistance, fungal development, pathogenesis, and virulence. Among the factors contributing to these processes, transporters play a central role in fungal biology, regulating nutrient acquisition, metabolite exchange, ion homeostasis, and drug efflux. However, the composition and diversity of transporter systems in C. auris remain poorly defined. Through genomic analysis, we identified 686 transporters and 125 accessory factors involved in transport in C. auris, most of which had not been characterized. These transporters and accessory factors were classified into seven classes, 22 subclasses, and 215 families, reflecting substantial functional diversity. Comparative analyses with other pathogenic Candida species and Saccharomyces cerevisiae reveal lineage-specific divergence in several transporter families. We also integrated multiple publicly available RNA-seq datasets encompassing antifungal drug exposure and drug-resistant isolates and identified subsets of transporters that are transcriptionally responsive in distinct antifungal conditions, including members of families implicated in drug transport, metabolism, and ion homeostasis.

Given the increase in cases associated with C. auris, it is essential to evaluate new candidates with antifungal potential. In this context, flavonoids represent a promising source for the development of new therapeutic alternatives. In this study eleven flavonoids were evaluated for their antifungal activity against C. auris strains from clades III and IV. The flavonoids showed dose-dependent inhibition of C. auris growth. Toxicity tests were conducted using the in vivo Tenebrio molitor model. The flavonoids exhibited toxicity levels either comparable to or lower than reference antifungals. Also, the study examined the ability of the flavonoids to inhibit efflux pumps. Some of the flavonoids (quercetin, fisetin, hesperetin, luteolin and apigenin) reduced efflux pump activity, which is an important feature since these pumps actively expel antifungal drugs from the cell, reducing the drug's effectiveness. This suggests that the flavonoids might inhibit efflux pump activity, potentially enhancing the efficacy of antifungal treatments. The study supports the potential of flavonoids as new therapeutic agents for C. auris. Since they target efflux pumps, which are a significant mechanism of resistance in C. auris, flavonoids could be used either alone or in combination with existing antifungals to improve treatment outcomes.",

Recently, there has been excitement about the promise of advances in protein structure modeling to generate hypotheses about sequence-structure-function relationships. Here, we leverage structural similarity to identify rapidly evolving proteasome assembly chaperones and characterize their function in Candidozyma (Candida) auris. Despite extensive sequence divergence, we demonstrate conservation of function, corroborating that specific folds, and not sequences, are required for function. This theoretical premise suggests that protein structures with certain properties should be functionally interchangeable, even if they were not products of a common evolutionary history. To reduce this theory to practice, we performed structure-informed protein design, exploring sequence space that is not accessible via stepwise evolution, and mutated more than 40 residues in the Poc4 proteasome assembly chaperone to demonstrate that artificial proteins can rescue complex biological processes in the context of the whole cell. This sequence-structure-function relationship expands our ability to use structure to identify deep evolutionary relationships between proteins and generate hypotheses about gene function in non-model organisms. Overall, this helps to define and understand functional constraints on protein evolution, with important implications for both future protein design and retrospective function prediction.",

This fungal pathogen is notable for its thermotolerance and a strong attachment capability that confers environmental persistence and immune evasion. Here, we compared strains from five clades of C. auris: clade I = South Asia (CDC 387), clade II = East Asia (CDC 381), clade III = Africa (CDC 384), clade IV = South America (CDC 385), and clade V = Iran (CDC 1097) for their ability to regulate cell surface hydrophobicity and biofilm. The hydrophobicity varied for each C. auris clade, with strains 384, 385, and 1097 displaying the highest hydrophobicity levels. C. auris strains had variable biofilm levels when compared among clades and had lower or similar biofilm levels when compared with Candida albicans at different temperatures. Comparison of mass spectrometry analysis of proteolytic digestates of cells from strains with low or high hydrophobicity revealed putative surface hydrophobic proteins. These included homologs to Candida albicans Als3 and IFF proteins, and their contribution to hydrophobicity and biofilm formation was confirmed with gene-deficient (knockout) C. auris strains. We conclude that several proteins contribute to C. auris surface hydrophobicity. Candidozyma auris (Candida auris) is an emerging pathogenic microorganism that is rapidly gaining attention due to outbreaks in health care facilities and its multidrug resistance. Its origin has yet to be determined, but genotypic analyses have pointed toward a simultaneous independent emergence of the different clades, possibly implicating climate change as a major factor in its recent appearance as a fungal pathogen. In 2022, the World Health Organization placed C. auris in the critical priority group as the second greatest fungal threat globally. Due to limited immunological and proteomic studies of C. auris, we sought to elucidate possible virulence mechanisms and identify leading proteins that can be targeted by immunotherapies and new drugs.

Novel therapeutic strategies that combine potent antifungal activity, low host toxicity, in vivo stability, and a reduced propensity for resistance development are urgently needed. Antimicrobial peptides (AMPs) stand out as a promising class of compounds to combat antimicrobial resistance. Leveraging the unique properties of AMPs, we previously developed a novel approach to synthesize random peptide mixtures (RPMs) with robust bactericidal activity against drug-resistant bacteria. Here, we evaluate the antifungal potential of RPMs and demonstrate species-dependent, broad-spectrum activity of FK20 (L-phenylalanine-L-lysine, 20-mer) against major human fungal pathogens, including Candida spp., Cryptococcus neoformans, and Aspergillus fumigatus, with particularly high potency against the multidrug-resistant pathogen Candida auris. Mechanistic analyses revealed rapid membrane and cell wall disruption accompanied by intracellular penetration, consistent with membrane-active antifungal activity. Importantly, experimental evolution assays demonstrated a markedly reduced capacity for resistance development in C. auris. FK20 inhibited biofilm formation and displayed substantial activity against mature, pre-formed biofilms, both alone and synergistically in combination with caspofungin. Finally, FK20 showed significant therapeutic efficacy in a murine model of systemic candidiasis. Collectively, these findings establish RPMs as a versatile antifungal platform with broad-spectrum activity, biofilm efficacy, and a low resistance footprint, highlighting their promise as a novel therapeutic strategy against drug-resistant fungal infections. The rising prevalence of invasive fungal infections, particularly among immunocompromised individuals, has become a critical public health concern. However, antifungal drug development has not kept pace with this growing need, and treatment options remain limited to a small number of drug classes. The emergence of multidrug-resistant fungal pathogens, such as Candida auris, further exacerbates this crisis by reducing the efficacy of existing therapeutics and increasing the risk of treatment failure. In this study, we evaluate the antifungal potential of FK20, a random peptide mixture (RPM) composed of L-phenylalanine and L-lysine. FK20 displays potent activity against C. auris and other clinically relevant Candida species, impairs biofilm formation, and exhibits synergy with caspofungin. Importantly, FK20 limits the emergence of resistance and demonstrates therapeutic efficacy in a murine model of systemic candidiasis. These findings establish RPMs as a promising new class of antifungals with broad-spectrum activity and clinical potential against drug-resistant fungal infections.",

These isolates are often associated with indwelling urinary catheters, a primary risk factor for catheter-associated urinary tract infections (CAUTIs). Despite its clinical prevalence, the mechanisms of C. auris colonization and pathogenesis within the bladder remain poorly understood. In this study, we screened C. auris isolates from diverse clades using an in vitro biofilm model and in vivo murine models of uncomplicated UTI and CAUTI. While in vitro biofilm formation varied among isolates, the presence of a catheter in vivo significantly enhanced fungal burden in the bladder. Notably, one strain (B11103) caused rapid systemic dissemination and mortality. To address this, we evaluated a liquid-infused silicone (LIS) catheter coating, which has previously shown efficacy against other uropathogens. The LIS coating significantly reduced C. auris attachment in vitro and, crucially, mitigated fungal burden on both the catheter and bladder tissue in vivo across all tested strains. For the hypervirulent B11103 strain, LIS catheters also significantly reduced dissemination to the kidneys and bloodstream. Furthermore, cytokine analysis revealed that C. auris CAUTI upregulates IL-6, CSF3, and CXCL1; importantly, this damaging inflammatory response was also dampened by the LIS catheter. These findings demonstrate that catheterization potentiates C. auris pathogenicity and identify LIS catheters as a promising, antimicrobial-sparing strategy to prevent colonization, systemic spread, and inflammation during C. auris CAUTI.IMPORTANCEThis research addresses the critical public health challenge posed by the emergence of Candidozyma auris, elucidating its pathogenesis in the urinary tract, the second-most common yet understudied reservoir. Here, we find that C. auris exhibits plasticity in its ability to form biofilms in urine and cause uncomplicated urinary tract infections (UTIs) and catheter-associated UTIs (CAUTIs). Importantly, we show that our liquid-infused silicone (LIS) catheters effectively disrupt this cycle by reducing fungal burden, preventing systemic spread, and dampening the damaging host inflammatory response. This work establishes the urinary tract as a critical niche for systemic entry and provides a validated strategy for infection prevention. Urinary catheters make C. auris dangerous, but this liquid-infused silicone coating is fighting back.",

Our evaluation across Southern Nevada demonstrates that upstream sewage monitoring at healthcare facilities provides significant sensitivity (p\u2009<\u20090.001) compared to wastewater treatment plant sampling. By combining amplicon sequencing and MALDI-TOF mass spectrometry, we identify clinically-relevant, resistance-associated variants in wastewater samples, while whole-genome sequencing reveals >90% genomic concordance between 443 wastewater-derived genomes and 2945 clinical isolates. We also detect previously unreported subclades and resistance mutations, including FKS1 Phe635Leu and co-occurring ERG11/FKS1 variants in wastewater samples up to nearly five months before their appearance in clinical settings. Transcriptomic profiling of drug-resistant isolates under antifungal and stress conditions identifies previously uncharacterized adaptation mechanisms, including differential regulation of ribosomal assembly pathways and cell cycle checkpoints. These findings highlight how wastewater intelligence can enhance traditional public\u00a0health approaches for early detection and monitoring of C. auris outbreaks and antifungal resistance.",
        "42003596": "ID: 42003596\nTitle: Role of the transcription factor Wor2 in biofilm formation of Candidozyma auris.\nAbstract: The yeast pathogen Candidozyma (Candida) auris can form biofilms, which contribute to its virulence and nosocomial transmission. In this study, we identified the transcription factor Wor2 as a negative regulator of biofilm formation in C. auris. Wor2 hyperactivation in a strain of clade IV via the use of a protein tagging strategy resulted in downregulation of two important adhesins, SCF1 and ALS4112, and decreased biofilm-forming capacity. We showed that the impact on biofilm was predominantly mediated via decreased SCF1 expression in this strain. However, results of adhesion assays on inert surfaces and human keratinocytes found relatively modest roles of Wor2 and Scf1 in this process, suggesting that their effect on biofilm formation is complex and not limited to the adhesion step. Finally, analyses of other strains from different clades identified three distinct WOR2 genotypes, with variable WOR2 expression levels and distinct impacts of WOR2 deletion on biofilm formation. Notably, Wor2 negatively regulated biofilm in strains of clades I, III, and IV with distinct profiles of SCF1/ALS4112 expression, while it had no impact on biofilm in a clade II strain. Taken together, this study showed that Wor2 exhibited some distinct genotypic evolution in C. auris resulting in clade- or strain-specific regulatory roles and pathways in biofilm formation.IMPORTANCECandidozyma (Candida) auris is a pathogenic yeast exhibiting a particular capacity for interhuman transmission via medical instruments, which was the cause of nosocomial outbreaks of candidemia. Adhesion to inert surfaces and subsequent biofilm formation is therefore important for C. auris propagation. This work highlights the role of the transcription factor Wor2 as a negative regulator of biofilm formation in C. auris. In a strain of clade IV, Wor2 was shown to downregulate two important adhesins (SCF1 and ALS4112). Interestingly, Wor2 exhibited different genotypes across C. auris clades and strains, which were associated with distinct differential expression of WOR2, ALS4112, and SCF1, and possibly distinct roles in biofilm formation.",

Its dissemination is driven by patient movement and asymptomatic carriers. However, molecular epidemiological studies linking imported cases to local strains in large metropolitan areas remain limited. To analyse the molecular epidemiology and resistance mechanisms of 33 clinical isolates in Shanghai and propose an integrated infection control strategy tailored to metropolitan healthcare settings. Isolates from 19 patients were identified via MALDI-TOF MS and sequencing. Antifungal susceptibility and biofilm formation were assessed. Environmental contamination was evaluated using PCR. Whole-genome sequencing (WGS) was employed to identify resistance mutations and perform phylogenetic analysis. All 33 isolates were fluconazole-resistant. Resistance to amphotericin B and echinocandins was observed in 9 and 4 isolates, respectively. All echinocandin-resistant strains harboured the Fks1-S639F mutation. Phylogenetic analysis revealed that Clade III (South African clade) was the dominant lineage. Colonisation was concentrated in the urinary tract and inguinal regions, while bedside tables were identified as key environmental reservoirs. All strains exhibited strong biofilm-forming capacity. ICU patients serve as primary reservoirs, with transmission driven by interregional movement. The distinct colonisation patterns and environmental hotspots provide specific targets for screening. Integrating PCR-based environmental monitoring with culture methods constitutes an effective strategy. These findings underscore the need for a standardised protocol integrating molecular diagnostics to optimise infection control in urban hospitals.",

PeAfpA and PeAfpB from Penicillium expansum show different activity profiles and potency, with PeAfpA being more active. Based on the PeAfpB solved structure, we had previously designed PeAfpB-PeAfpA chimeras that showed different properties. From these, we engineer here two additional variants, chPeAFPV6 and chPeAFPV7, that revealed novel aspects of the AFP structure, antifungal determinants and mechanism. chPeAFPV6, with a single E11K mutation in the loop L1 that is part of the \u03b3-core motif, increased PeAfpB antifungal activity to that of PeAfpA against filamentous fungi but not yeasts, and promoted internalisation into Penicillium digitatum hyphae. However, changes in loop L3 of PeAfpB as in chPeAFPV7 abolished this increase, resulting in an inactive protein that still internalised. Overall, internalisation is neither sufficient nor essential for killing P. digitatum. Antifungal activity did not correlate with reactive oxygen species production, suggesting that oxidative burst is a fungal stress defence rather than a killing mechanism. Although cell permeabilisation was associated with antifungal activity, it does not seem to be a primary mode of action. Structural analysis showed interactions between the \u03b3-core motif and loop L3, and suggests the importance of the conformation of the E7 residue of PeAfpB. Additionally, PeAfpA was identified as a protein able to penetrate Candida auris by a cell wall-dependent mechanism, and kill yeast cells. This study highlights the potential of the PeAfpB scaffold for engineering new-to-nature AFPs and provides novel insights into their modes of action, paving the way for future applications. KEY POINTS: A single amino acid change in the \u03b3-core of PeAfpB enhances antifungal potency Loop L3 of PeAfpB may block activity through interaction with the \u03b3-core Antifungal activity does not correlate with ROS production.",

Candida auris): epidemiology, biology, and antifungal resistance.\nAbstract: SUMMARYThe emerging fungal pathogen Candidozyma auris (syn. Candida auris; C. auris) has attracted considerable attention from the scientific, clinical, and public health communities due to its multidrug resistance, environmental persistence, and high transmissibility. Since its first description in Japan in 2009, C. auris has spread rapidly worldwide, with a marked acceleration following the coronavirus disease 2019 (COVID-19) pandemic. As of December 2025, 84,941 colonization or infection cases have been reported across 82 countries spanning 6 continents. In this review, we summarize the current knowledge of the biology and global epidemiology of C. auris. We first examine its taxonomy, proposed origins, and key biological, genetic, and phenotypic characteristics, with particular emphasis on factors underlying environmental persistence, transmission dynamics, antifungal resistance, and virulence. Drawing on published literature and publicly available surveillance data from national public health authorities worldwide, we provide an updated overview of the global epidemiological landscape and evolving transmission patterns of C. auris. Finally, we discuss potential strategies to mitigate the continued and escalating global spread of this emerging multidrug-resistant fungal pathogen.",

These traits enable it to persist and be continuously transmitted in the environment, posing significant challenges for preventing and controlling clinical infections. Our study aimed to elucidate the phylogenetic relationships of C. auris isolates collected in China, and to explore the tolerance of C. auris to antifungal drugs and disinfectant agents commonly used in hospital. This study also intended to comprehensively characterize the drug resistance genes and amino acid substitutions in C. auris. METHODS: Whole-genome sequencing was used to identify and construct a phylogenetic tree for 8 strains of C. auris. The minimum inhibitory concentration (MIC) and minimum bacterial concentration (MBC) of antifungal agents against C. auris isolates were determined using broth dilution. Quantitative suspension tests were conducted to evaluate the killing effects of different disinfectant agents on C. auris isolates. Resistance genes and mutation sites were identified using bioinformatic analysis. RESULTS: Five isolates of C. auris were closely related to the C. auris B13916 (clade I) and three isolates were closest to B17721 (clade III). All isolates showed resistance to fluconazole; five of them showed reduced susceptibility to amphotericin B. Compared with Candida albicans, benzalkonium chloride, didodecyl dimethylammonium chloride, chlorhexidine gluconate, and hydrogen peroxide showed increased MIC and MBC values against C. auris isolates. Under specific conditions, the anti-fungal effects of benzalkonium chloride, chlorhexidine gluconate, sodium hypochlorite, ethanol, and povidone-iodine were effective. however, didodecyl dimethylammonium chloride and hydrogen peroxide were less effective. C. auris isolates exhibited amino acid substitutions in ERG11, ERG2, ERG4, CIS2, TAC1, and CDR1. They also possessed resistance genes associated with antimicrobial target alterations and efflux pump. CONCLUSIONS: The decreased susceptibility of C. auris to fluconazole, amphotericin B, didodecyl dimethylammonium chloride, and hydrogen peroxide, which could be attributed to resistance genes and single-nucleotide mutations, reminds medical institutions to rationally select the type, concentration, and exposure time of antifungal agents targeting C. auris. The emergence of C. auris resistance to antifungal drugs and disinfectant agents may involve common molecular mechanisms involving nucleotide mutations, requiring further studies.",

Current antifungals are often insufficient, creating a need for host-directed strategies. Sirtuin 3 (SIRT3) is a mitochondrial deacetylase that regulates redox homeostasis, but its role in antifungal macrophage defense is not well defined. We examined how SIRT3 shapes macrophage responses to C. auris. We also evaluated ethyl caffeate (EC) as a host-directed modulator. We used murine macrophages with Sirt3 knockdown or overexpression. We quantified phagocytosis, intracellular fungal survival, mitochondrial ROS dynamics, and macrophage cell integrity using imaging, flow cytometry, CFU assays, and LDH release. We profiled infection-induced transcriptional programs by RNA-seq and performed pathway analyses. We tested EC both in vitro and in systemic infection models in Drosophila and mice. We assessed pathway markers by immunoblotting and immunofluorescence. We used the SIRT3 inhibitor 3-TYP to test inhibition sensitivity. SIRT3 deficiency impaired macrophage antifungal function and was accompanied by redox imbalance. mtROS regulation was disrupted in a biphasic pattern, with an early spike followed by late depletion. Transcriptomics linked SIRT3-dependent programs to FOXO and PI3K-AKT signaling. In macrophages, SIRT3 status tracked with FOXO3A acetylation and AKT phosphorylation. EC showed weak direct antifungal activity in vitro but improved outcomes in systemic infection models. EC treatment increased SIRT3 abundance and was associated with reduced FOXO3A acetylation and restrained infection-associated AKT activation. These functional and signaling effects were largely sensitive to SIRT3 inhibition by 3-TYP. This study connects SIRT3-dependent redox control to FOXO3A-AKT signaling during C. auris infection. It also supports EC as a host-directed candidate that improves antifungal defense in vivo while limiting inflammatory injury.",

This study evaluated the impact of a comprehensive infection-control intervention on hospital-acquired C. auris cases by comparing two post-implementation periods, phase I (2021-2022) and phase II (2023-2025), to assess the intervention's performance over time. Methods\u00a0 A retrospective analysis was conducted on 323 patients diagnosed with C. auris between 2021 and 2025. Infection-control measures were initiated at the end of 2021 as part of the institutional response to the detection of the initial cases and were consistently maintained until the end of the study. Chi-square tests were applied to compare demographic and clinical characteristics across the two periods. Results The majority of patients with C. auris were male (65.3%), and more than half (51.4%) were over 65 years of age. Demographic and clinical characteristics were similar between the two periods. However, the proportion of patients with documented contact with a C. auris-positive individual significantly decreased over time, from 56.9% in phase I (2021-2022) to 40.8% in phase II (2023-2025) (p = 0.004). Monthly hospital-acquired C. auris cases decreased from 6 cases per month in phase I to 5 cases per month in phase II, representing a 16.7% reduction; however, this difference was not statistically significant (p = 0.41). Conclusion\u00a0 The multidisciplinary infection-control intervention significantly reduced contact-associated transmission and hospital-acquired C. auris cases. The results show that multidisciplinary collaboration, improved screening, and enhanced environmental cleaning and disinfection all help control C. auris in high-risk healthcare settings.",

Since its initial discovery in 2009, C. auris has spread rapidly across continents and is now classified by both the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO) as a critical-priority pathogen. This review summarizes current knowledge on the origin, taxonomy, microbiology, and virulence mechanisms of C. auris, emphasizing its thermotolerance, osmotolerance, and biofilm-forming capacity on biotic and abiotic surfaces, as well as aspects related to its antifungal drug resistance and management. These features, together with its genomic plasticity, contribute to persistence, transmission, and drug resistance.

We provide a genomic epidemiologic description of 1,535 C. auris isolates collected in the United States during 2013-2022. We identified clades I, II, III, and IV but not clades V or VI. Median pairwise single-nucleotide polymorphism distances indicated lower intraclade relatedness for clades I (91), III (43), and IV (43), compared with clade II (1,455). Phylogenetic analysis showed regional clusters with varying predominant clades. Of 809 isolates that underwent antifungal susceptibility testing, 53 were echinocandin resistant, distributed across 3 clades; 92% (49/53) had FKS1 hotspot mutations, which varied regionally. Our findings corroborate ongoing transmission and clonal expansion of C. auris, likely propagated by multiple introductions within and between geographic regions. Echinocandin resistance in multiple clades highlights the need to increase awareness, improve treatment practices, and engage in rapid public health response.",

Although echinocandin resistance in Candida is typically associated with fitness loss, we found that micafungin-resistant C. auris strains (MICAevo) generated from two distinct source isolates (AR0381 and AR0387) via experimental microevolution retained full virulence. Evolved strains developed stable resistance to multiple echinocandins, while AR0387 (B8441), originating from MICAevo strain, also acquired increased azole tolerance. Whole-genome sequencing revealed clinically relevant mutations in FKS1, as well as changes in genes involved in ergosterol biosynthesis (ERG3), amino acid metabolism, and PKA signaling. Despite in vitro sensitivity to cell wall stressors, resistant strains maintained or even enhanced colonization in a murine systemic infection model. Independently evolved strains showed similar antifungal resistance profiles, and although minor differences of pathogenic potential were noted, no consistent virulence attenuation was observed, indicating the reproducibility of phenotype changes. These findings suggest that C. auris can acquire echinocandin resistance without compromising pathogenicity, supporting its persistence and spread in clinical settings.",

A total of 596 C. auris isolates from 37 healthcare centers were collected. Antifungal susceptibility was performed and ERG11 gene was sequenced for 45 representative isolates. The ERG11 and efflux pump (MDR1 and CDR1) expression under fluconazole drug pressure was assessed by quantitative reverse-transcription polymerase chain reaction (n = 20) along with cell wall ergosterol content estimation. Short tandem repeat (STR) genotyping was done on 235 isolates. The highest number of isolates (50.1%) was recovered from northern India, followed by eastern (27.6%) and southern India (13.6%). The majority of the isolates were recovered from private sector hospitals. A total of 80.0% and 27.9% of isolates were resistant to fluconazole and voriconazole, respectively. A notable increase in resistance to amphotericin B and caspofungin was observed, with 3.2% of isolates being multidrug resistant. In ERG11, Y132F and K143R mutations were present in both fluconazole-susceptible and -resistant isolates; in addition, 50% of fluconazole-susceptible isolates showed elevated ERG11 expression and ergosterol content upon fluconazole treatment. Basal level cell wall ergosterol was higher in fluconazole-susceptible isolates. All isolates belonged to clade I with STR genotyping. Our study demonstrates high levels of antifungal resistance in the largest collection of Indian C. auris clinical isolates reported to date. Besides mutations and gene expressions, other pathways conferring drug resistance, such as stress response, must be studied to further understand the evolution of this pathogen.",

We evaluated the performance and clinical utility of the Roche cobas eplex blood culture identification fungal pathogen panel (BCID-FP). Although used in fewer than 1% of patients with blood cultures drawn, BCID-FP identified fungal pathogens in more than 96% of tested samples within 72\u2005hours. Over a 3-year period, BCID-FP demonstrated a positive percent agreement (PPA) of 91.7% compared to culture (n = 327). PPA was 100% for Candida auris, Candida kefyr, Candida krusei, Candida tropicalis, Candida parapsilosis, and Candida neoformans; slightly lower for Candida albicans (90.3%) and Candida glabrata (91.1%); and lowest for Candida lusitaniae (55.6%) and Fusarium spp. (0%). To assess clinical impact, we compared patient records from preimplementation (results withheld from providers; n = 31) and postimplementation (results released; n = 68). Compared to the T2Dx Candida panel, BCID-FP showed superior accuracy (PPA 98.0% vs 61.7%). It also reduced time to fungal identification by 1.36 days relative to culture (P < .0001). Postimplementation, there was also a significant increase in infectious disease physician recommendations for antifungal deescalation (39.7% vs 16.1%; P = .0219), typically shifting from micafungin to fluconazole in C. albicans and C. parapsilosis cases. However, no significant differences were observed in time to antifungal optimization, empiric therapy duration, length of stay, or mortality.

Recent detection of C. auris in natural environments suggests the existence of an environmental reservoir, prompting investigation into the potential role of azole fungicides used for plant protection in the development of resistance to antifungals used in human medicine. Here, we assessed the impact of azole fungicides on in vitro resistance development in two C. auris strains (B11220 and B11221) through sequential exposure to epoxiconazole, propiconazole, or tebuconazole. Exposure resulted in a rapid and significant increase in fungicide MICs, accompanied by a reduced susceptibility to four azole antifungals (fluconazole, voriconazole, posaconazole, isavuconazole), and to a new antifungal agent, the manogepix. Several strains with elevated MICs exhibited stable phenotypes and were associated with a mutation in the TAC1B gene. One of these strains showed a significant overexpression of the efflux pump CDR1. These findings provide experimental evidence that azole fungicides can drive resistance to azole antifungals and reduce susceptibility to manogepix, underscoring the need for integrated One Health antifungal stewardship strategies to combat C. auris. Candida auris is a yeast that causes infection in humans and has been detected in the environment. We have shown that fungicides used in agriculture can reduce the susceptibility of C. auris to antifungal drugs used in human medicine.",

This study presents data from the first year of a national, long-term surveillance program. All microbiologically confirmed candidemia cases in patients hospitalized at 30 Czech centers in 2023 were evaluated. This study assessed BSI incidence per 100,000 inhabitants, species distribution, and antifungal susceptibilities (EUCAST E.Def 7.4 protocol) of strains.aff Whole-genome sequencing was performed on selected isolates with acquired resistance or non-wild-type phenotypes to determine the molecular mechanisms of resistance. In total, 433 isolates from 408 unique BSI episodes in 398 patients were recorded in 2023. Candida albicans was the most frequent species (40.6%), followed by Candida glabrata (24.5%), Candida parapsilosis (14.5%), and Candida tropicalis (5.5%). In pediatric patients, C. albicans (58.8%) was the most common, followed by C. parapsilosis (17.6%). Candida auris BSI was not detected in 2023. The highest rates of acquired fluconazole resistance were detected in C. parapsilosis (16.9%) and C. glabrata (15.4%). Most fluconazole-resistant (FLC-R) C. parapsilosis isolates carried Y132F mutation in ERG11 gene (14/15; 93.3%). One isolate of C. glabrata was resistant to echinocandins (1.3%), but remained susceptible to azoles, mutations in FKS1 (G14S) and FKS2 (S663P, T926P) were identified. This nationwide survey provides the first comprehensive yeast BSI surveillance data from the Czech Republic, which spans the entire country. CR follows trends observed in developed countries, with a decline in C. albicans and a rise in C. glabrata infections. To our knowledge, this is the first report describing FLC-R C. parapsilosis isolates carrying the Y132F ERG11 mutation in CR. These findings highlight several emerging challenges that reflect global trends: a shifting spectrum of Candida species from C. albicans to non-albicans species, and rising levels of acquired azole resistance. Therefore, continuous national monitoring is essential.",

Distinct from other clinically prevalent fungal pathogens such as Candida species, C. auris employs unique defense mechanisms against the host immune system, including immune evasion and survival strategies. This review summarizes the distinct strategies used by C. auris to resist host immune responses. In particular, C. auris exhibits pronounced genomic and morphological plasticity, which facilitates rapid adaptation to host-derived stressors. Its modified cell wall, characterized by a thicker mannan layer, efficiently masks immunogenic \u03b2-glucan, thereby reducing immunogenicity. Furthermore, multicellular features, including robust biofilms and unique aggregative forms, enhance colonization, transmission, and stress resistance. C. auris also secretes diverse virulence factors and undergoes adaptive metabolic reprogramming under nutrient limitation, promoting more efficient immune evasion and survival within the host. Collectively, these flexible defensive strategies confer enhanced host immune resistance, contributing to its heightened pathogenicity. This review provides novel perspectives on future research directions and potential therapeutic strategies for managing C. auris infections.",

Italy experienced a large nosocomial outbreak in early 2020, with subsequent sporadic cases or small clusters in different regions.AIMTo provide an overview of the C. auris population structure, genomic diversity, and spread in Italy.METHODSGenome sequences from Italian C. auris isolates (n\u2009=\u200968) were obtained either from public databases, or by whole-genome sequencing of available isolates (n\u2009=\u200917) from previously uncharacterised and/or recently emerged (2025) cases. The sequence dataset was complemented with whole genome sequences of international isolates (n\u2009=\u2009139) to conduct a global phylogenetic analysis based on core-genome single nucleotide polymorphisms. Genetic mutations associated with antifungal resistance were investigated.RESULTSAll Italian isolates belonged to clade\u2009I (South Asian) but were interspersed among different subclades. Subclade\u2009Ic isolates were of a single lineage, characterised by the HMG1P238H mutation. This lineage spread over four regions. Subclade\u2009Ib members were more diverse, and associated with local or imported single cases, as well as nosocomial clusters following sporadic, independent C. auris introductions from countries in southern Europe. A putative new subclade (Id) was identified, involving isolates from Italy and an eastern European country. Subclades\u2009Ib-c-d exhibited lineage-specific genetic signatures in antifungal-resistance-associated loci (CDR1, ERG11, TAC1B).CONCLUSIONSIn Italy, C. auris strains form a complex population, resulting from emergence or evolution of clade\u2009I sub-lineages following, in some instances, sporadic introductions from other European countries. Strengthened screening protocols remain essential for inter-facility transfers and for patients with prior healthcare exposure abroad.",

The emergence of Candidozyma (Candida) auris and other resistant fungal pathogens presents a risk to critically ill patients. Whole-genome sequencing has the potential to improve public health and clinical surveillance for fAMR and could enable more rapid detection. In this review, we discuss the mechanisms of fAMR and the strengths and limitations of the currently available databases and bioinformatic tools for the detection of fAMR from genomic data.

Here, we integrate pangenomic analysis with global essentiality screening to establish a foundational understanding of the C. auris genome and identify potential therapeutic targets. We performed pangenome analysis on 695 outbreak strains of C. auris selected to be genetically representative of publicly sequenced genomes. After using BLAST to refine the pangenome, we found that 96.8% of gene families were core, with the remaining high-confidence accessory gene families primarily consisting of gene loss events or clade-specific genes. The high proportion of core genes emphasizes the clonal nature of these outbreak strains, but comparative analysis with the closely related C. haemuli species complex suggested that most of these core genes are functionally dispensible. To examine this hypothesis, we developed a novel insertional mutagenesis approach that leverages the promiscuous integration of linear DNA in the C. auris genome. This global analysis identified 614 high-confidence essential genes. Crucially, nearly one-third of these genes, including the conserved translation initiation factor Sui1, exhibit divergent essentiality patterns compared to the model yeasts Candida albicans and Saccharomyces cerevisiae. These findings highlight organism-specific biology that would be overlooked by orthology alone. By combining pangenomic diversity with functional essentiality, this study provides a comprehensive resource for identifying species-specific determinants of virulence and prioritizing novel targets for antifungal drug development.",

The structures of these compounds were characterized by a combination of spectroscopic studies, ECD calculations, and ECD experiments induced by Rh2(OCOCF3)4. Acrenoid A (1) features a distinctive 5/5/7 tricyclic ring framework. Moreover, all isolates were evaluated for their antifungal activities. Notably, compound 9 exhibited potent antifungal activity against drug-resistant Candida auris 12766, with a MIC of 4\u202f\u03bcg/mL. In addition, compound 9 exhibited low hemolytic toxicity. The antifungal mechanism of compound 9 involves cell membrane disruption and intracellular ROS accumulation. In addition to these effects, it also inhibited biofilm formation in C. auris 12766. These findings highlight compound 9 as a promising antifungal candidate for treating C. auris.",

This study aims to compare the clinical characteristics, risk factors, antifungal resistance profiles, and mortality rates of candidemia caused by C. auris and non-auris Candida spp. (NACS). This retrospective cohort study was conducted at a tertiary care hospital from 2021 to 2024. Patients aged 18 years and older with positive blood cultures for Candida spp. were included. Demographic data, comorbidities, risk factors, mortality rates, and treatment protocols were analyzed. A total of 1,088 candidemia cases were included in the study (C. auris: 126 cases, NACS: 962 cases). The length of hospital stay was significantly longer in the C. auris group compared to the NACS group (50.98\u2009\u00b1\u200938.79 vs. 33.05\u2009\u00b1\u200925.57 days, p\u2009<\u20090.001). Independent risk factors for C. auris candidemia included longer hospitalization before candidemia (OR 1.01, 95% CI 1.01-1.02, p\u2009<\u20090.001), chronic obstructive pulmonary disease (OR 1.89, 95% CI 1.07-3.31, p\u2009=\u20090.026), prior antifungal use within 30 days (OR 1.92, 95% CI 1.22-3.03, p\u2009=\u20090.005), and ICU admission (OR 2.08, 95% CI 1.10-3.92, p\u2009=\u20090.023). Antifungal resistance rates among C. auris isolates were 96.49% for fluconazole, 72.81% for amphotericin B, and 25.89% for caspofungin. The 30-day mortality rate was lower in the C. auris group (48.4%) compared to the NACS group (60.2%) (p\u2009=\u20090.012). Although crude 30-day mortality was lower in the C. auris group, adjusted analysis showed comparable 30-day mortality between the C. auris and NACS groups.

We conducted a PRISMA-guided systematic review with exploratory random-effects quantitative synthesis of peer-reviewed experimental studies evaluating ECM composition, matrix-associated regulatory pathways and antifungal susceptibility in Candida biofilms. Qualitative synthesis mapped ECM components and pathways, while harmonizable semi-quantitative data were summarized as directional modeled estimates. Of 38 full-text records assessed, 33 primary studies were included in the qualitative synthesis and 25 contributed to the exploratory pooled analysis. Preservation or modulation of ECM-associated mechanisms showed a strong modeled directional association with reduced antifungal susceptibility (pooled modeled odds ratio: 4.28, 95% CI: 4.06-4.52). \u03b2-1,3-glucan was the most consistently supported sequestration scaffold, particularly for azoles and polyenes. Mannan-glucan complexes, matrix proteins, extracellular DNA and vesicle-associated lipids provided complementary structural and remodeling functions. Non-albicans Candida species, especially Candida glabrata and Candida auris, more often combined ECM protection with efflux-linked resistance. ECM-mediated resistance in Candida biofilms is multilayered, species-dependent and drug-class specific. These findings support species-aware interpretation of biofilm-associated antifungal resistance and further development of ECM-directed adjunctive strategies.",

It is associated with invasive infections, particularly in critically ill patients exposed to broad-spectrum antibiotics and invasive procedures. Pediatric patients in intensive care units are at increased risk owing to the use of mechanical ventilation, parenteral nutrition, central venous catheters, and antimicrobial agents. A systematic review of the literature was conducted in the PubMed, Embase, and Scopus databases between January 2011 to January 2025. Sixteen studies met the inclusion criteria, totaling 110 pediatric cases of C. auris infection. Most cases were reported in Colombia (45.5 %), followed by the United States (18.1 %) and Venezuela (15.4 %). Coinfections were identified in 10.9 % of cases, mainly involving Enterobacter spp., Klebsiella spp., and Staphylococcus spp. Bloodstream infection was the main clinical presentation (93.6 %), and the median time to isolation of C. auris was 20.3 days. The most commonly used antifungals in isolated cases were voriconazole (38.9 %), amphotericin B (35.2 %), and caspofungin (33.3 %). Mortality was 39.1 %, while 52.7 % survived. Multiple antifungal combinations have been reported, with amphotericin B and micafungin being the most common. Among 33 clinical isolates, high resistance to fluconazole (60.6%) and variable susceptibility to amphotericin B were observed. Echinocandins, such as micafungin and anidulafungin, showed greater efficacy, although resistance to caspofungin has been reported. C. auris in pediatric patients represents a growing challenge, especially in preterm neonates, due to high antifungal resistance and diagnostic difficulties.",

C. auris has emerged as an important fungal pathogen because of its capacity for healthcare-associated colonization, environmental persistence, biofilm formation, laboratory misidentification, and multidrug resistance. Available evidence suggests that its rapid global spread is related to environmental tolerance, skin colonization, interclade phenotypic differences, and antifungal resistance mechanisms. Reported cases from T\u00fcrkiye further support the need for strengthened infection control and surveillance systems. It represents a significant nosocomial fungal threat that necessitates the simultaneous implementation of clinical management and public health responses. In addition, it has been observed that the dominant clade in T\u00fcrkiye is Clade I, that early cases were misidentified due to laboratory method-related limitations, and that there are substantial variations in antifungal susceptibility even within the same case series.",
        "42229743": "ID: 42229743\nTitle: Antifungal peptides for biofilm disruption: Mechanisms, design strategies, and translational outlook.\nAbstract: Invasive fungal infections in intensive care units are a serious concern, especially when they are associated with biofilm formation. These infections often lead to high mortality because biofilms make the fungi more resistant to antifungal drugs and harder for the immune system to clear. Pathogens such as Candida auris, Candida albicans, and Aspergillus fumigatus are particularly problematic, as they are known to develop multidrug resistance and cause persistent infections in critically ill patients. These biofilms often show a much higher tolerance to standard antifungal drugs and can escape the host body's immune defenses. This makes the infections they cause more persistent and very difficult to treat in clinical practice. Antifungal peptides (AFPs), whether derived from natural host-defense molecules or designed through rational engineering, are emerging as promising options for tackling fungal biofilms. They act through several mechanisms, such as disrupting the fungal cell membrane, blocking early adhesion and morphogenesis, and weakening the extracellular matrix. Importantly, they may also work in synergy with existing antifungal drugs, making treatment more effective. Recent progress in peptide engineering and delivery methods, such as nanocarriers and hydrogel-based systems has enhanced the stability, selectivity, and ability of peptides to target fungal biofilms in experimental models. At the same time, there are important challenges that remain, including their tendency to break down due to proteolytic enzymes, possible cytotoxic effects, difficulties in large scale manufacturing, and regulatory hurdles linked to peptide-based therapies. Overall, AFPs represent a promising and fast developing area of research, but their use in clinical practice is limited. More studies are needed to confirm their safety, effectiveness and practical feasibility for managing biofilm-associated fungal infections.",

This study was aimed to determine the proportion of C. auris among candidemia, evaluate automated antifungal susceptibility testing (AFST) against Broth Microdilution (BMD), and identify high-risk areas in a haematology unit. A prospective cross-sectional study (September 2024-September 2025) screened 3894 blood cultures in a Kolkata hospital. Isolates were identified via Vitek-2 and MALDI-TOF MS. Vitek 2 AFST results were compared with the gold-standard BMD. Spatial mapping was utilized to identify ward clustering. Excluding paediatric and non-haematology cases, the adult C. auris cohort (n\u00a0=\u00a038) was analysed (mean age 25.8\u00a0\u00b1\u00a011.2 years). All had haematological malignancy and neutropenia, with central venous catheters in 81.6% (n\u00a0=\u00a031). The 30-day crude mortality was 15.8% (n\u00a0=\u00a06). Diagnostically Vitek 2 demonstrated a critical 47.4% Major Error rate for Amphotericin B compared to BMD (P\u00a0< 0.001), significantly overestimating resistance. Spatial mapping identified persistent environmental reservoirs around specific high-traffic beds. Vitek 2 significantly overestimates Amphotericin B resistance, necessitating BMD verification to prevent inappropriate exclusion of polyene therapy. The infection burden in young, neutropenic adult highlights a vulnerable demographic. Persistence case clustering suggests environmental fomite colonization, requiring enhanced diagnostic stewardship and targeted sporicidal decontamination in haematology units. The resistant fungus Candidozyma auris is a severe threat to young leukaemia patients. We found that standard automated lab tests frequently misdiagnose its drug resistance. Manual testing is vital to ensure these vulnerable patients receive the correct, life-saving treatment.",

Here, we report a prevalent cluster of clinical C. auris strains with enhanced biofilm formation, a contributor to environmental and skin persistence. Genomic analyses show that the clinical isolates with enhanced biofilm formation ability carry a loss-of-function mutation in the WOR2 locus, which encodes a white-opaque switching regulator in Candida species. Analysis of 13,314 published genomes revealed that 3104 strains (23.3%) harbor nonsense or frameshift mutations in WOR2, indicating frequent clinical occurrence. Deletion of WOR2 in a clinical strain markedly increased biofilm formation, whereas reintroduction of an intact WOR2 significantly attenuated biofilm development. Further analyses show that Wor2 inactivation upregulates GFC1, ALS4, and multiple biofilm-associated genes. Together, these findings reveal a key regulatory mechanism underlying biofilm development, environmental persistence, and transmission of C. auris.",

This feature facilitates person-to-person transmission and contributes to healthcare-associated infections and outbreaks. In this study, both invasive C. auris infections and colonization were evaluated together. We aimed to compare clinical characteristics and healthcare-associated exposures between invasive and colonized cases and to assess antifungal susceptibility patterns in invasive infections. A total of 79 patients with C. auris isolation between December 2022 and April 2025 were retrospectively analyzed. Species identification was confirmed using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. Patients with C. auris isolated from invasive specimens, such as blood or tissue, were classified as having invasive infection, whereas those with isolation from non-invasive specimens such as axilla/groin swabs, nasal swabs, urine, catheters, and sputum, without concurrent invasive positivity, were classified as colonized. Patients with both screening and invasive positivity were included in the invasive infection group for comparative analyses. Antifungal susceptibility to amphotericin B, fluconazole, micafungin, and anidulafungin was determined on invasive isolates using the Sensititre YeastOne colorimetric microdilution method. Interpretation of results was based on the tentative breakpoints defined by the United States Centers for Disease Control and Prevention and the epidemiological cutoff values established by the European Committee on Antimicrobial Susceptibility Testing. Demographic characteristics, clinical variables, and healthcare-associated exposures were compared between the invasive infection and colonization groups. A total of 91 C. auris isolates from 79 patients were evaluated. Invasive infection was detected in 41 patients (52%) and colonization in 38 patients (48%). Most cases were observed in intensive care and palliative care units. Among screening sites, axilla/groin swabs showed the highest positivity rate. Central venous catheter use, intubation, surgical history, and decubitus ulcer were numerically more frequent among invasive cases; however, none of these differences reached statistical significance. Echinocandin resistance developed in two patients during follow-up. The median age was significantly higher in the invasive group than in the colonized group (74 vs. 64.5 years; p\u2009=\u20090.002). Accurate identification of C. auris and continuous antifungal susceptibility surveillance are essential for infection control. Older age was the only variable significantly associated with invasive infection, while other clinical and healthcare-associated exposures were common in both groups but did not differ significantly. All isolates were resistant to fluconazole, and echinocandin resistance emerged in two isolates. Amphotericin B susceptibility findings should be interpreted cautiously, as the use of Sensititre YeastOne without confirmatory reference testing may have overestimated resistance. Larger multicenter studies are needed to better define factors independently associated with invasive infection.",

This study aimed to describe the prevalence, disease patterns, and antifungal susceptibility patterns of C. auris isolates recovered from public-sector healthcare facilities in the greater Pretoria region from 2021 to 2024. A retrospective laboratory-based surveillance study was conducted using data from the National Health Laboratory Service Tshwane Academic Division laboratory. Isolates were classified as invasive or non-invasive based on specimen source. Temporal trends in antifungal minimum inhibitory concentrations (MICs) were analysed using interval-censored regression. A total of 592 C. auris isolates were identified. Blood cultures were the most frequent specimen source overall, comprising 237 isolates (40.03%). Intravascular catheter tip isolates predominated in 2023 and 2024, with 48 and 72 isolates, respectively. The proportion of invasive isolates declined from 56.8% to 40.8% over the study period. Among tested isolates, fluconazole resistance exceeded 99%. Resistance to amphotericin B and echinocandins was uncommon, with eight total isolates identified. Decreasing MIC trends were observed for amphotericin B (\u03b2 = -0.059 per year; p = 0.012) and micafungin (\u03b2 = -0.081 per year; p = 0.026).

This study aimed to evaluate the in vitro and in vivo antifungal activity of Cymbopogon nardus (L.) Rendle essential oil and citral oil, both free and incorporated into liposomes, against C. auris. The liposomes were composed of a lipid phase containing soy phosphatidylcholine, ergosterol, cholesterol and oleylamine, along with an aqueous phase consisting of PBS. The liposome was characterized by measuring the following features: hydrodynamic size, polydispersity index, zeta potential, transmission electron microscopy, infrared vibrational spectroscopy, thermogravimetry and differential scanning calorimetry, and transmission electron microscopy. The antifungal activity of the C. nardus essential oil, the citral oil and liposome-loaded compounds was determined by minimum inhibitory concentration (MIC), biofilm assay and by a Galleria mellonella infection model. G. mellonella was also used to assess acute in vivo toxicity. The liposomes exhibited sizes ranging from 218.8 to 261.7nm, polydispersity index <0.5, and a positive zeta potential. Furthermore, the liposomes showed good stability and a lipid layer in the outer region. Citral showed the best antifungal activity, with MIC 62.5\u03bcg/mL, being the compound selected for its incorporation into liposomes, which further improved its antifungal potential. Citral and citral-liposomes showed important metabolic inhibition in mature biofilms (20%). No acute toxicity was observed for either sample in G. mellonella, and citral-liposomes showed promising antifungal action in the G. mellonella infection model.

Peer-reviewed primary studies published between 2009 and September 2025 were included if they reported clade attribution and antifungal susceptibility or resistance data. PubMed/MEDLINE, Scopus, and Web of Science were searched. Two reviewers independently screened studies and extracted data using a standardized form. Of 2050 records identified, 105 studies met inclusion criteria, representing 29 countries and diverse study designs. Whole-genome sequencing was the most common typing method. Antifungal susceptibility varied substantially across clades. High fluconazole resistance was consistently reported (MIC 4 to >256\u03bcg/mL). Echinocandins generally retained activity, although reduced susceptibility associated with FKS1 mutations was observed. Resistance mechanisms primarily involved mutations in ERG11, FKS1, and efflux-related genes.

We show that glucose starvation induced by major fungal pathogens Candida albicans and Candida auris causes macrophage lysis by activating NINJ1, the executioner of membrane rupture during cell death. In glucose-starved macrophages, NINJ1 ruptures membranes independently of known cell death programs. Consistently, NINJ1 is the dominant effector of fungal-induced macrophage damage amongst host cell death factors. Supplementation of the amino acid alanine rescues glucose-starved macrophages better than glucose, and it does so by inhibiting NINJ1 oligomerization. Moreover, C. albicans infection disrupts amino acid metabolism in mice and reduces serum alanine. Finally, NINJ1-mediated membrane rupture enables C. albicans egress from macrophages together with the toxin candidalysin. We establish the mechanism of glucose starvation-induced macrophage damage by NINJ1, and demonstrate the roles of NINJ1 and alanine in immune responses to Candida and fungal escape.",

In this three-year surveillance study (2022-2025), 357 non-duplicate Candida bloodstream isolates from a tertiary care centre in northern India were analysed to characterize species distribution, extracellular virulence phenotypes, virulence-associated genes, and antifungal susceptibility profiles. Species identification was performed using phenotypic methods and confirmed by PCR-RFLP and MALDI-TOF MS, while antifungal susceptibility testing followed CLSI M27-A3 guidelines. Non-albicans Candida species predominated (76.8%), with Candida tropicalis as the most frequent isolate, followed by Candida albicans and Candidozyma auris. Multiplex PCR demonstrated a high prevalence of virulence-associated genes (HWP1, ALS1, SAP2, and PLB1), with concordance between gene detection and phenotypic expression of adhesion, biofilm formation, and extracellular enzyme activity. Echinocandins retained potent in vitro activity across species, whereas C. auris exhibited a multidrug-resistant phenotype, including high fluconazole resistance and reduced susceptibility to amphotericin B and caspofungin. Species-stratified analyses revealed significant positive correlations between esterase and hemolysin activity and amphotericin B minimum inhibitory concentrations in C. albicans and C. tropicalis (p\u2009<\u20090.01). Multivariate analysis identified elevated amphotericin B MICs and specific virulence traits as independent predictors of strong biofilm formation.

Untargeted LC-HRMS/MS analysis revealed a complex metabolomic profile dominated by hydroxycinnamic acid derivatives, including caffeoylquinic acids, alongside a diverse flavonoid fraction comprising quercetin, kaempferol, apigenin, and acacetin derivatives. The presence of sugars and organic acids further indicated a broad metabolic composition. The evaporated liquid residual extract exhibited strong antioxidant activity (DPPH: 32.54, ABTS: 27.80, FRAP: 35.95 mmol GAE/100 mg). Pronounced antibacterial activity was observed against both Gram-positive and Gram-negative bacteria, including Staphylococcus aureus, MRSA, Listeria monocytogenes, Escherichia coli, and Pseudomonas aeruginosa (MICs 0.5-1 mg/mL). Additionally, the extract demonstrated antifungal activity against Candida auris and Candida parapsilosis, as well as strong antibiofilm effects against P. aeruginosa (up to 95.52% inhibition). Molecular docking supported these findings, revealing strong binding affinities of key phenolics toward the bacterial targets FabI and D-Ala-D-Ala ligase. Overall, the results highlight the potential of this by-product for nutraceutical and pharmaceutical applications.",

Its high environmental persistence, immune evasion, phenotypic heterogeneity, and multidrug resistance are major contributors to its high mortality rate. Under diverse environmental conditions, C. auris exhibits marked phenotypic plasticity, switching from non-aggregative to aggregative form and, in some contexts, pseudohyphal-like morphotypes. However, the significance of this heterogeneity in pathogenesis and drug tolerance remains poorly understood. This review provides a comprehensive overview of how external cues influence C. auris morphotypes, with particular emphasis on aggregation. It further highlights the role of adhesion-associated genes (ALS4112 and SCF1) in mediating cell aggregation and examines their evolutionary trajectories across Candida species and among distinct C. auris clades. In addition, we discuss emerging molecular mechanisms that may underlie differential morphotypes and their links to virulence and antifungal tolerance. Evidence suggests that mannan-mediated masking of pathogen-associated molecular patterns (PAMPs) in the aggregative phenotype may contribute to persistence and reduced virulence in the host. Overall, C. auris can remodel its cell wall and elicit distinct host immune responses based on its form, opening avenues for novel therapeutic strategies which further require deeper experimental validation.",

Infection poses major diagnostic and treatment challenges due to its phenotypic similarity to other Candida spp. and multiple antifungal resistance. Despite its emergence in Vietnam, the level of understanding among healthcare professionals is unknown. This study explores the knowledge, attitudes, and practices toward C. auris of registered physicians and nurses in a Vietnamese hospital intensive care unit (ICU). A mixed-methods study was conducted in an international standards-accredited Hanoi private general hospital. It comprised a self-administered cross-sectional survey containing 46 questions distributed to the ICU staff, followed by an in-depth semi-structured interview of selected participants. The survey covered demographic, knowledge, attitudes, and practices domains and utilized Likert-type and ranking scales. Descriptive and analytical statistics were applied to quantitative data and thematic analysis to qualitative insights. A total of 32 ICU staff completed the survey, but only 11 (34.38%) scored above 50%. Knowledge was associated weakly with age and work experience but not gender or profession. Most participants recognized C. auris as an important ICU pathogen and expressed a positive attitude to institutional preparedness but revealed confusion about the site of infection, means of diagnosis, most effective agents for treatment, and best PPE practices to prevent infections. Of the 12 participants selected for in-depth interview, only two were familiar with the WHO guidelines on C. auris. The concerns centered on access to treatment, especially for immunocompromised patients. The opinions on outbreak likelihood varied, with some staff citing poor infection control in public hospitals as a risk, while others considered an outbreak unlikely due to low prevalence and the restricted mode of transmission. For multiple reasons, the private sector was perceived as better prepared than the public sector. This study reveals a knowledge gap regarding C. auris among ICU physicians and nurses in Hanoi caring for high-risk patient populations. The findings underscore a need for targeted continuing medical education, enhanced antifungal stewardship strategies, and revised infection control protocols to combat this clinically important emerging pathogen in Vietnamese hospitals.",

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) is widely used for rapid micro-organism identification and has recently been explored for antifungal susceptibility testing (AFST).Hypothesis. Although MALDI-TOF MS has emerged as a promising tool for AFST, simplified and clinically applicable strategies for rapid fluconazole (FLZ) susceptibility detection in Candida spp. remain insufficiently validated. We hypothesized that a streamlined AFST-MS approach would demonstrate good categorical agreement (CA) with the European Committee on Antimicrobial Susceptibility Testing (EUCAST) reference method while significantly reducing turnaround time.Aim. To establish a simplified MALDI-TOF MS-based AFST approach for detecting FLZ resistance in Candida species.Methodology. Fifty-one clinical isolates and reference strains were incubated for 3 h in the presence of FLZ at two concentrations (32 and 4 \u00b5g ml-1) and in drug-free controls. Spectral profiles were compared with the EUCAST reference method.Results. Overall CA between AFST-MS and EUCAST was 85.2% (\u03ba=0.7306). Species-specific accuracy was 100% for Candida auris, Pichia kudriavzevii (formerly Candida krusei), Candida tropicalis and Candida parapsilosis; 92.9% for Candida albicans and 40% for Nakaseomyces glabrata (formerly Candida glabrata); however, these estimates should be interpreted cautiously given the limited number of isolates per species. All discrepancies were minor errors, with no major or very major errors observed. The method reduced analysis time from 24 to 3 h and enabled presumptive FLZ susceptibility detection with good overall agreement with the reference methodConclusion. These findings support the potential of MALDI-TOF MS as a rapid adjunct tool for antifungal susceptibility assessment and may contribute to earlier therapeutic decision-making.",

This study aimed to determine the effect of phenotypic switch on C. auris biofilm formation and virulence gene expression in mono- and co-culture with Staphylococcus aureus. Phenotypic switching was induced by prolonged incubation, and biofilms were developed in RPMI-1640, YEPD, SDB, and BHIYE. The biofilm biomass and total cell count were measured. SAP5 and ALS5 gene expression was quantified using qPCR. The 4th switched generation mono-culture biofilm in BHIYE produced the highest biomass (3.34\u2009\u00b1\u20090.08) and total cell count (5.66\u2009\u00b1\u20090.03 log10 cells mL-1). In addition, SAP5 and ALS5 expression peaked in the 2nd switched generation mono-culture by 10.43\u2009\u00b1\u20090.44-fold and 4.764\u2009\u00b1\u20090.01-fold, respectively. Co-culture biofilms exhibited significantly higher ALS5 expression in selected switched generations compared to unswitched C. auris (p\u2009<\u20090.05). In conclusion, phenotypic switching enhanced biofilm formation and modulated the expression of SAP5 and ALS5 in C. auris.",

Prospective observational surveillance study. Tertiary academic hospital in Northern Greece. Hospitalized patients undergoing active MDRO screening based on predefined infection prevention and control criteria. A pathogen-focused analysis was conducted using data from a prospective MDRO surveillance program between October 2024 and January 2025. Screening swabs were obtained from the rectum and groin. Target organisms included multidrug-resistant (MDR) Klebsiella pneumoniae, Pseudomonas aeruginosa, vancomycin-resistant enterococci (VRE), Candida auris, and Acinetobacter spp. Pathogen-specific detection yields were calculated for each anatomical site. Among 1,206 screening swabs, 308 (25.5%) were positive for at least one MDRO. Rectal swabs detected 95.8% of Klebsiella pneumoniae (K. pneumoniae) (92/96), 100% of VRE (59/59), and 66.7% of Pseudomonas aeruginosa (46/69). In contrast, 88.9% of Candida auris cases (24/27) were identified exclusively from groin swabs. Reliance on rectal screening alone would have missed nearly 90% of Candida auris carriers, whereas groin-only screening would have failed to detect most K. pneumoniae and all VRE carriers. Anatomical site selection critically influences MDRO surveillance sensitivity. Rectal screening is optimal for MDROs colonizing the gastrointestinal tract, whereas groin sampling is essential for detecting Candida auris. Pathogen-targeted, site-specific surveillance strategies may substantially improve detection efficiency and optimize infection prevention efforts in high-prevalence hospital settings.",
        "42346566": "ID: 42346566\nTitle: Recent Outbreaks, Resistance Trends, and Control Measures in Candida auris and Candida glabrata Infections.\nAbstract: The global rise in multidrug-resistant (MDR) fungal pathogens has positioned Candida auris and Candida glabrata as major threats to public health. In recent years, these pathogens have increasingly been reported beyond traditional hospital settings, including neonatal intensive care units, long-term care facilities, oncology wards, and post-pandemic critical care environments. International surveillance bodies, including the Centers for Disease Control and Prevention (CDC), European Centre for Disease Prevention and Control (ECDC), World Health Organization (WHO), and regional monitoring networks, have documented escalating antifungal resistance, complex outbreak dynamics, and persistent gaps in infection control implementation. C. auris has emerged as a major etiological agent of healthcare-associated outbreaks, particularly in intensive care and neonatal units. Surveillance data indicate that a high proportion of C. auris isolates exhibit resistance to azoles, often exceeding 80% in some regions, while echinocandin resistance remains variable. Resistance patterns have evolved from predominantly azole resistance to broader multidrug-resistant phenotypes, including treatment-emergent echinocandin resistance. Six genetically distinct clades (I-VI) have been identified, with Clades I, III, and IV associated with large-scale outbreaks, whereas available data suggests that Clades II, V, and VI are more geographically restricted, although evidence for the recently described clades remains limited. C. glabrata is increasingly recognized as a major cause of invasive candidiasis, with rising resistance reported across multiple regions. While reduced azole susceptibility was historically predominant, emerging evidence highlights rising dual azole-echinocandin resistance, adaptive microevolution during antifungal therapy, and biofilm-associated tolerance mechanisms. Despite these advances, significant gaps persist in global resistance surveillance and in the mechanistic understanding of virulence and antifungal adaptation. Current mitigation strategies include antifungal stewardship programs, expanded resistance testing, and strengthened surveillance systems. Advances in rapid diagnostic technologies such as matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry, polymerase chain reaction (PCR)-based assays, and genomic surveillance have improved pathogen identification and outbreak detection, although accessibility remains limited in resource-constrained settings. This review examines emerging epidemiological, genomic, and antifungal resistance trends in C. auris and C. glabrata and highlights key priorities for improving diagnosis, surveillance, stewardship, and management of multidrug-resistant Candida infections.",

In this study, we built a machine learning model using four variables available at identification to estimate resistance probability in real time. Methods: We analysed 747 fungal isolates from 725 ICU patients (January 2021-March 2026). We trained and compared a Random Forest and a Logistic Regression model, evaluating both with temporal cross-validation, permutation feature importance, three-category (S/I/R) prediction, and calibration analysis. Results: Multidrug resistance doubled from 24.5% (2021) to 51.1% (2025), and Candida auris grew eight-fold in three years. Random Forest reached AUC 0.885 on the held-out test set and 0.848 on prospective 2024-2025 data (Brier score 0.093). Species identity and drug choice together explained 87% of predictive signal. Local C. albicans fluconazole resistance (~16%) far exceeded the ECMM European figure of 0%, and C. krusei was four times more prevalent than the continental average. Conclusions: A four-variable model may provide calibrated resistance estimates during the critical gap before susceptibility results return, though performance reflects predominantly deterministic species-drug patterns rather than complex learned biology. Overall performance was comparable to a rule-based lookup table, confirming that the majority of predictive signal derives from established species-drug susceptibility patterns. Meaningful added value is limited to temporal trend tracking and improved prediction where resistance is acquired rather than intrinsic (C. albicans, C. tropicalis hard-subset AUC 0.929 vs. rule-based 0.899). The model complements a local antifungal testing; it does not replace one.",

This rapid expansion is defined by its unique population structure consisting of six distinct genomic clades with starkly different evolutionary trajectories, phenotypic traits, and clinical risks. We conducted a systematic synthesis of literature from PubMed, Scopus, and Google Scholar (2009-2026), focusing on comparative genomics, clade-specific virulence, and diagnostic accuracy. A total of 64 studies were analyzed to identify patterns in clade divergence and antifungal resistance. Our analysis reveals that C. auris is not a monolithic threat but a complex of diverse lineages with specialized adaptations. Clade I (South Asian) and Clade IV (South American) represent the highest clinical risk due to hyper-virulence and high rates of multi-drug resistant (MDR) strains. In contrast, Clade II (East Asian) was initially associated with localized ear infections; recent genomic data show an expanding pathogenic profile with emerging bloodstream infections. Our review also identifies Clade V (Iranian) as a genetically distinct group and highlights the recent identification of Clade VI (Indomalayan) as a distinct lineage, suggesting a long-standing environmental reservoir. Furthermore, we identify critical \"blind spots\" in automated diagnostic platforms (VITEK\u00ae 2, BD Phoenix) where phenotypic variations in Clades II and III lead to frequent misidentification as Candida haemulonii or Candida famata. This review proposes a \"clade-aware\" framework for public health. While frontline antifungal treatment remains standardized regardless of lineage, we argue that effective long-term management and outbreak containment require integrating genomic surveillance with clade-specific infection control. By identifying high-biofilm clades (Clade I) or hyper-virulent lineages (Clade IV), public health systems can implement more targeted containment strategies, moving toward a precision-based approach to managing this fungal pathogen.",

Disinfectant efficacy is variable, particularly under high organic load, with reports of reduced susceptibility to Candida albicans. The aim of this study was to define the intrinsic chemical susceptibility of Candido auris clades I-IV and assess whether yeasticidal efficacy against Candida albicans predicts activity against Candido auris. Quantitative suspension tests (NEN-EN 13624:2022, dirty conditions) were used to evaluate six disinfectant chemistries: organic acid (lactic acid), halogen (chlorine), quaternary ammonium compounds, alcohol (ethanol), and oxidising agent (hydrogen peroxide). Testing was conducted in two independent laboratories using Candida albicans ATCC 10231 and Candido auris clades (I-IV). All chemistries achieved a \u22654 log10 reduction against Candida albicans and all Candido auris clades at validated conditions, with no consistent clade-dependent differences. Organic acid formulations showed comparable efficacy, highlighting a potential sustainable alternative. Candido auris shows susceptibility comparable with that of Candida albicans.

In this scenario, biotransformation has emerged as a complementary innovation strategy for antimicrobial discovery because it expands the chemical space around bioactive scaffolds through selective enzymatic or whole-cell modification. Among the available biocatalysts, fungi are especially attractive due to their metabolic plasticity and broad enzymatic repertoire, including cytochrome P450 monooxygenases, unspecific peroxygenases, laccases, peroxidases, and hydrolases. Current evidence shows that fungal systems can mediate regio- and stereoselective transformations of xenobiotics, aromatics, steroids, terpenes, and lipids, generating structurally refined metabolites of pharmacological and biotechnological interest. This narrative review discusses where fungal biotransformation currently stands as a platform for antimicrobial innovation, highlighting representative enzyme-characterized examples, the main fungal groups and catalytic systems involved, and the experimental workflows used to evaluate these processes. Particular emphasis is given to assay design with growing cells, resting cells, and isolated enzymes, as well as to analytical monitoring by time-course sampling, LC-HRMS/MS, dereplication, molecular networking, isolation, and structural elucidation.

To describe epidemiologic and laboratory characteristics and trends of HAIs and AMR, 2020-2024, using surveillance and laboratory data submitted by hospitals to the Canadian Nosocomial Infection Surveillance Program (CNISP) and by provincial and territorial laboratories to the National Microbiology Laboratory. Data was collected from 109 Canadian sentinel acute care hospitals between January 1, 2020 and December 31, 2024 for Clostridioides difficile infections (CDI), methicillin-resistant Staphylococcus aureus (MRSA) bloodstream infections (BSIs), vancomycin-resistant Enterococcus (VRE) BSIs (specifically Enterococcus faecalis and Enterococcus faecium), carbapenemase-producing Enterobacterales (CPE) and carbapenemase-producing Acinetobacter baumannii (CPA) infections and colonizations and Candidozyma auris (C. auris; formerly Candida auris) infections. Trend analysis for case counts, incidence rates (rates), outcomes, molecular characterization and AMR profiles are presented. From 2020 to 2024, rates remained relatively stable for CDI (range: 5.01-5.38 infections per 10,000 patient days) and MRSA BSI (range: 0.99-1.16 infections per 10,000 patient days) and increased significantly for VRE BSIs (from 0.30 to 0.42 infections per 10,000 patient days; p=0.01).

In this study, we employed a targeted drug-repurposing strategy to identify novel indications for existing FDA-approved compounds against C. auris, leading to the identification of Tavaborole as a potent fungistatic agent. Tavaborole displayed robust activity across all five tested clades of C. auris, as well as against Candida albicans and Candida glabrata. To investigate drug resistance mechanisms of C. auris, we applied quantitative proteomics analyses following exposure to Tavaborole and Amphotericin B (AmB), complemented by electron microscopy. Proteomic profiling revealed that C. auris mounts distinct but overlapping adaptive responses to antifungal stress, involving stress response pathways, metabolic reprogramming and amino acid biosynthesis. While Tavaborole primarily induced targeted stress adaptation, AmB triggered a broader, multi-pronged resistance response including oxidative stress mitigation, osmolyte production and metabolic remodeling. Shared alterations in glycogen metabolism and amino acid biosynthesis suggest conserved antifungal adaptation mechanisms. Altogether, this study highlights Tavaborole as a promising antifungal candidate against C. auris, sheds novel insights into drug resistance mechanisms employed by the pathogen and delivers a drug-repurposing procedure highly customizable to target other microorganisms.",

However, the molecular mechanisms underlying its virulence remain incompletely understood. In this study, we performed in vivo transcriptome analysis using an immunosuppressed mouse gastrointestinal infection model to identify genes associated with host adaptation and virulence during infection. By comparing fungal transcriptomes obtained from colonization and dissemination sites with those from\u00a0in vitro cultures, we identified genes that were consistently upregulated during infection. Among these genes, the unfolded protein response regulator HAC1 was selected as a candidate virulence-associated gene for further analysis. Reverse transcription PCR and sequencing analyses revealed that\u00a0HAC1 mRNA in C. auris undergoes an unconventional splicing event of 287 bp that is enhanced under endoplasmic reticulum stress conditions. The excised region spans the annotated open reading frame boundary, suggesting that the translated region of\u00a0HAC1 may require re-evaluation. Notably, a proportion of HAC1 transcripts appeared to be spliced even under non-stress conditions, indicating a detectable basal level of the unfolded protein response. Differences in splicing dynamics were also observed among clade strains. Functional analyses demonstrated that deletion of\u00a0HAC1 increased sensitivity to endoplasmic reticulum stress. The HAC1 deletion mutant also exhibited reduced virulence in both Galleria mellonella and immunosuppressed mouse infection models, as evidenced by delayed host mortality and decreased fungal burdens, respectively. These findings indicate that HAC1 contributes to endoplasmic reticulum stress adaptation and survival in the host environment and identify\u00a0HAC1 as a virulence-associated gene in C. auris. Candida auris is an emerging multidrug-resistant fungal pathogen. Using in vivo transcriptome analysis, we identified HAC1 as a regulator of endoplasmic reticulum stress adaptation and virulence in infection models.

Its accurate and timely identification is critical for infection prevention, yet conventional culture-based methods are limited by slow growth, morphological ambiguity, and potential misidentification. This multicenter study evaluated the performance of the Simplexa C. auris Direct assay using 2,020 axilla/groin swab specimens collected from six clinical sites compared to culture followed by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS). Specimens were tested prospectively (n = 1,930) and retrospectively (n = 90), with demographic data spanning inpatient, intensive care unit, emergency department, and long-term acute care hospital settings. Discordant results were resolved by bi-directional sequencing, targeting the internal transcribed spacer and D1/D2 regions of the 28S ribosomal DNA gene. Compared to culture followed by MALDI-TOF MS identification, the Simplexa assay demonstrated an overall sensitivity of 94.8% and specificity of 98.7%, with a Cohen's kappa of 0.80, indicating strong agreement. Discordance rates were low (1.4%), and diagnostic accuracy was high (98.6%). The limit of detection was 127 CFU/mL for Clade I and 260 CFU/mL for Clade IV. Mean cycle threshold values were significantly lower in culture-positive specimens (25.1, 95% CI, 23.6-26.7) compared to culture-negative ones (33.6, 95% CI, 32.1-35.0; P < 0.0001). Comparative analysis with four lab-developed molecular tests (LDTs) showed low rates of discordance: 0.9% for LDT 1 and 2, 1.5% for LDT 3, and 0% for LDT 4, indicating a high level of agreement between the molecular methods. The Simplexa C. auris Direct assay provides a rapid and reliable alternative to traditional methods, providing results in under 2 h, supporting early detection and containment of C. auris in healthcare settings. Rapid and accurate detection of Candida auris colonization is essential for preventing healthcare-associated outbreaks and reducing mortality.

During 2022-2024, a total of 13,507 clinical C. auris cases were reported to CDC, increasing from 2,882 in 2022 to 4,428 in 2023 and 6,197 in 2024, with smaller annual percentage increases over time (53.7% from 2022 to 2023 and 39.9% from 2023 to 2024). Most clinical cases occurred among adults aged \u226545 years (87.8%) and among males (61.0%). The most common specimen types among all clinical cases were urine (31.5%) and blood (30.2%); by year, the proportion of blood as the specimen type was 34.4% in 2022, 30.2% in 2023, and 25.6% in 2024. Most clinical cases were identified through specimens collected in acute care hospitals (76.6%) and long-term acute care hospitals (17.8%).During the same period, a total of 27,853 screening cases were reported to CDC, increasing from 6,226 in 2022 to 9,195 in 2023 and 12,432 in 2024. Screening cases most frequently occurred among adults aged \u226545 years (90.0%) and males (57.9%). Among cases with known facility type, the proportion of specimens collected in acute care hospitals increased from 24.7% in 2022 to 50.7% in 2024, whereas the proportion of specimens collected in long-term acute care hospitals decreased from 56.1% to 35.7% during the same period. The number of clinical and screening C. auris cases reported to CDC increased during 2022-2024, indicating ongoing transmission in U.S. health care settings. Although annual percentage increases in clinical cases declined over time, absolute case counts reported to CDC continued to rise. The increasing proportion of screening cases with specimens collected in acute care hospitals might reflect increased use of screening in acute care hospitals, including screening at admission. Because of increases in the number of reported C. auris cases, sustained infection prevention and control efforts in health care facilities, including adherence to transmission-based precautions, environmental disinfection with agents effective against C. auris, and communication of C. auris status during patient transfers remain essential to preventing clinical infections and colonization. Because this pathogen is frequently resistant to antifungal drugs, continued investment in laboratory capacity and surveillance, including antifungal susceptibility testing and screening of patients at high risk for C. auris infection, can support timely detection and guide prevention strategies. Ongoing public health coordination at federal, state, and local levels is critical to limit further spread and to address emerging antifungal drug resistance.",

Its ability to survive in hospital environments, resist common antifungals, and affect critically ill patients makes it a major global health concern. Understanding local epidemiology and susceptibility patterns is essential to guide prevention and management strategies. Objective This study aimed to describe the temporal distribution and antifungal susceptibility patterns of\u00a0C. auris\u00a0at a tertiary care hospital in Oman (2017-2021) and compare clinical characteristics, risk factors, and outcomes between colonized and infected patients, including candidemia and non\u2011candidemia subgroups. Methods This retrospective, single\u2011center study included all patients with at least one C. auris-positive culture at Khoula Hospital, a tertiary care hospital in Oman (2017-2021). Species identification and susceptibility testing were performed using the VITEK\u00ae 2 system (bioM\u00e9rieux,\u00a0Marcy-l'\u00c9toile,\u00a0France) and confirmed at the Central Public Health Laboratories. Clinical and epidemiologic data were extracted from electronic medical records. Patients were classified as colonized or infected based on clinical and microbiologic findings, and the infected group was further subclassified into candidemia and non-candidemia subgroups. Statistical comparisons used Mann-Whitney U, chi-square, or Fisher's exact tests, and odds ratios (OR) with 95% confidence intervals (CI) were calculated for categorical variables, with significance at p < 0.05. Results A total of 129 patients (130 isolates) were identified. Cases peaked in 2019 and declined thereafter. Of all patients, 51 (39.5%) had confirmed infection, and 78 (60.5%) were colonized. Candidemia was the predominant invasive presentation (39/51, 76.5%). Infected patients had longer hospitalization (median, 73 versus 57.5 days;\u00a0p = 0.027) and higher central venous catheter\u00a0use (74.5% versus 56.4%; OR, 2.25; 95% CI, 1.04-4.89;\u00a0p = 0.037) than colonized individuals. Crude mortality was higher in infected than colonized patients (43.1% versus 28.2%, p = 0.080). Among infected patients, candidemia was associated with greater mechanical ventilation use (94.9% versus 66.7%; OR, 9.25; 95% CI, 1.44-59.51;\u00a0p = 0.008) and central-line utilization (82.1% versus 50.0%; OR, 4.57; 95% CI, 1.13-18.47;\u00a0p = 0.026). Crude mortality was higher in candidemia than non-candidemia infections (48.7% versus 25.0%, p = 0.14). Susceptibility testing showed universal fluconazole resistance (100%), very limited amphotericin B activity (5.2%), intermediate voriconazole susceptibility (44.8%), and preserved echinocandin activity (caspofungin, 96.6%; micafungin, 100%) and flucytosine activity (80.0%). Conclusions The findings demonstrate that C. auris imposes a considerable burden on hospitalized patients, with marked morbidity in those who develop invasive disease, particularly candidemia. The organism's persistent multidrug resistance, with its capacity for sustained transmission, highlights the need for strengthened infection-control practices and continuous surveillance. Preservation of echinocandin susceptibility supports their role as first-line therapy, while high prevalence of azole and amphotericin B resistance emphasizes the importance of targeted antifungal stewardship and early risk identification to reduce both transmission and adverse clinical outcomes.",

Among them, nonribosomal peptides (NRPs) stand as one of the most therapeutically significant classes, encompassing numerous approved anti-infective and anticancer agents. Yet, discovering bioactive NRPs remains profoundly challenging due to their complex biosynthesis and chemical architecture. Here, we present NPDiscover, a pathogen-oriented, scalable bioinformatics platform that integrates genome mining, metabolomics, and machine learning to identify NRPs active against drug-resistant pathogens. Applying NPDiscover to Actinobacteria datasets, we discovered edaphochelin A, a previously unreported NRP that kills multi-drug-resistant Candida auris and Candida glabrata by disrupting respiratory chain proteins. Structural elucidation via nuclear magnetic resonance and mass spectrometry, alongside in vitro and in vivo validation, confirmed its efficacy, safety, and a mode of action distinct from existing antifungals-establishing edaphochelin A as a compelling drug candidate and NPDiscover as a powerful engine for scalable natural product discovery.",
        "42390249": "ID: 42390249\nTitle: Disinfectant tolerance of Candidozyma auris and Candida albicans biofilms evaluated using the bead assay for biofilms.\nAbstract: Candidozyma auris (formerly Candida auris) has emerged as a critical nosocomial pathogen, notable for its multidrug resistance and its capability to form biofilms that enable persistence on surfaces. Although effective disinfection strategies are urgently needed, current disinfectant efficacy standards in many regions, such as Europe, are primarily based on testing planktonic Candida albicans and do not adequately reflect the resilience of Candida biofilms, including those of C. albicans and C. auris. To address this gap, the Bead Assay for Biofilms, previously developed for bacterial biofilms, was adapted for the first time to eukaryotic cells. The goal was to cultivate C. auris and C. albicans biofilms and evaluate the efficacy of selected disinfectants across four active substance classes. Cell enumeration demonstrated highly reproducible biofilms, whose architecture was confirmed by scanning electron microscopy. Both an alcohol- and a QAC-based product did not achieve sufficient reduction of at least \u22654 log10 CFU/mL of biofilm-cells when applied under conditions recommended by the manufacturer (alcohol 1 min: C. auris 0.82, C. albicans 0.54; QAC 1%, 15 min: C. auris 1.94, C. albicans 0.68). This reduced efficacy is consistent with the known increased tolerance of microorganisms in biofilms. In contrast, peracetic acid and glutaraldehyde achieved sufficient reductions, albeit at relatively high concentrations (peracetic acid 0.1%: C. auris 4.75 and 0.05%: C. albicans 4.87; glutaraldehyde 0.5%: C. auris 5.32 and C. albicans 4.15). Our findings underscore the need to adapt disinfection protocols and testing models to consider biofilm formation of C. auris and C. albicans, and species-specific resilience.IMPORTANCEThis study highlights a critical gap in current disinfection efficacy testing standards; many of which rely on planktonic cell models and do not account for the resilience of biofilm-associated cells or emerging pathogens with unique resistance traits. Although species-specific regulatory guidance for C. auris exists in certain regions (e.g., in the USA), standardized disinfectant testing remains largely based on suspension assays (often using C. albicans) and does not routinely incorporate biofilm models. Using the Bead Assay for Biofilms, we demonstrate that several commonly used disinfectants may fail to inactivate biofilm-associated C. auris and C. albicans when applied as recommended. This suggests that reliance on planktonic testing may overestimate disinfectant efficacy against clinically relevant pathogenic yeast and highlights the need to expand current testing standards in order to include biofilm-associated pathogens to improve infection prevention strategies. Consequently, our research is of immediate relevance to regulatory bodies, infection control, and public health.",

In recent years, its detection in wastewater has raised concerns regarding the potential environmental dimensions of its dissemination and the associated public health implications. This study examines the current evidence on the occurrence of C. auris in wastewater, with an emphasis on the concentration, isolation, and identification methodologies employed in recent investigations. Framed within a One Health perspective, the analysis discusses potential pathways of environmental dissemination through wastewater effluents and biosolids, particularly in the context of the expanding reuse of treated wastewater and the land application of sewage sludge. The review also highlights existing regulatory gaps, including the absence of specific guidelines addressing pathogenic fungi in wastewater treatment plant byproducts as well as the lack of standardization in reported data, which hinders more in-depth analyses. Overall, this work identifies important knowledge gaps and emphasizes the need for further studies and interdisciplinary surveillance strategies to better understand the environmental circulation of C. auris. Additionally, a conceptual workflow is proposed to advance the standardization of analytical approaches and data reporting, contributing to strengthening public health, environmental protection, and sanitary policies.",
        "42405803": "ID: 42405803\nTitle: Candida spp. suppress neutrophil reactive nitrogen species to evade killing.\nAbstract: Candida albicans is a human commensal that can cause life-threatening invasive infection in immunocompromised individuals. Human immunity to C. albicans infection is thought to be largely dependent on neutrophil reactive oxygen and nitrogen species (ROS/RNS) generation by neutrophils. Despite this, our understanding of innate immune killing and escape by C. albicans is primarily studied in macrophages, and the precise mechanisms of evasion are unclear in neutrophils. Here, we sought to determine the importance of neutrophil reactive nitrogen species (RNS) production during C. albicans infection in vivo. Using a zebrafish model, we found that C. albicans rapidly downregulated neutrophil RNS below basal levels during the first day post-infection, a time at which neutrophil RNS is upregulated in bacterial infections as an important host-defense mechanism, indicating fungal evasion of host neutrophils. We confirmed the downregulation of RNS in human primary neutrophils and with clinical Candida isolates, including emerging human pathogens Candida auris and Candida glabrata. Inducible nitric oxide synthase (iNOS; Nos2 in zebrafish), the enzyme responsible for RNS production, competes with the arginase enzyme for a shared substrate, L-arginine. Using a zebrafish arginase2 transgenic line and a C. albicans car1\u0394 mutant, we showed that both host and fungal arginase contribute to the reduction in neutrophil RNS. Despite pathogen downregulation, upregulation of neutrophil RNS via hypoxia-inducible factor 1\u03b1 (Hif-1\u03b1) stabilization was sufficient to improve host survival following C. albicans infection. Inhibition of Nos2 blocked the host protective effect of Hif-1\u03b1 stabilization. Finally, restoration of neutrophil RNS via Hif-1\u03b1 stabilization was additive to clinically relevant antifungal treatment, increasing survival and clearance of C. albicans infections. Together, these data demonstrate that restoration of the neutrophil RNS response in C. albicans infection improves infection outcomes, highlighting the potential of targeting Hif-1\u03b1 and RNS in host-directed therapies against fungal infections.IMPORTANCECandida albicans is a fungus that normally lives harmlessly in the human body but can cause life-threatening infections in people with weakened immune systems. A key part of the body's defense against this fungus is neutrophils, immune cells that kill microbes using toxic molecules. However, how Candida avoids neutrophil defense is not well understood. Here, we used zebrafish and human immune cells to show that Candida suppresses an important neutrophil defense, reactive nitrogen species (RNS), during infection. Unlike bacteria, which trigger RNS, Candida reduces these protective molecules to below normal levels, helping its survival. This effect was also observed with other disease-causing Candida species. We went on to show that both the host and Candida contribute to this suppression. Importantly, boosting the neutrophil response improved survival and helped clear infection, especially when combined with standard antifungal drugs. These findings suggest new ways to support the immune system alongside existing treatments.",
        "42405804": "ID: 42405804\nTitle: Morphotype-specific susceptibility to Neosartorya (Aspergillus) fischeri antifungal protein 2 is associated with an anabolic transcriptional signature in Candida.\nAbstract: The emergence of drug-resistant Candida species has created a demand for global antifungal strategies that extend beyond classical growth inhibition to target unknown vulnerabilities of fungal pathogens. In this study, we demonstrated that the Neosartorya (Aspergillus) fischeri antifungal protein NFAP2 selectively targets early morphogenetic states of Candida albicans and Candidozyma auris, revealing a transient window of susceptibility during filament and pseudohypha formation. Integrated transcriptomic and in vivo analyses indicate that these developmental states may represent context-dependent entry points for NFAP2 activity. In C. albicans, transcriptomic and network analyses indicate the presence of an anabolic, translation-associated gene expression signature, accompanied by suppression of stress-protective pathways, which is associated with increased susceptibility of emerging hyphae to NFAP2 but does not establish a direct causal mechanism. In C. auris, increased susceptibility of pseudohyphal cells occurred without overt transcriptional remodeling, consistent with the characteristically muted gene expression responses of this species, suggesting that NFAP2 sensitivity is governed primarily by biophysical and post-transcriptional mechanisms rather than transcriptional reprogramming. Importantly, morphotype-specific vulnerabilities observed in vitro were reflected in distinct in vivo outcomes in Galleria mellonella, as NFAP2 was well tolerated and provided a moderate, transient survival benefit in pseudohyphal C. auris infections, but not in filamentous C. albicans, where a worsened outcome was observed, consistent with species- and morphotype-dependent activity. Taken together, these results suggest that early morphogenetic states of Candida are stress-sensitive phenotypes associated with increased susceptibility to NFAP2. This work provides a proof-of-concept framework for future investigation of morphotype-associated antifungal vulnerability to peptide-based antifungal strategies.IMPORTANCEDrug-resistant Candida species represent an escalating global health threat; however, most antifungal strategies continue to target fungal growth rather than intrinsic biological vulnerabilities. In this study, we identified early morphogenetic transitions as a shared window of increased susceptibility in both Candida albicans and the highly drug-resistant pathogen Candidozyma (formerly Candida) auris. By integrating transcriptomic profiling with in vivo infection models, we found that NFAP2 exhibits antifungal activity that is influenced by these transient developmental states in a context-dependent manner while remaining well tolerated by the host. We further demonstrated that morphotype-specific stress responses are associated with the divergent sensitivities of C. albicans and C. auris to NFAP2. These results support the concept that fungal morphogenesis may represent a therapeutically actionable process and provide a framework for designing antifungal strategies that target developmental states rather than growth. This strategy may open new opportunities for improving protein- and peptide-based therapies, as well as combination therapies against difficult-to-treat fungal pathogens.",

The multidrug-resistant fungal pathogen Candida auris poses a critical and escalating threat to global public health. Characterized by rapid nosocomial transmission, persistent environmental contamination, and resistance to multiple antifungal classes, C. auris challenges healthcare systems worldwide. Its independent emergence across distinct geographic clades and exponential rise in cases, exacerbated by the COVID-19 pandemic, underscore the urgent need for robust, coordinated response. This review synthesizes the current knowledge on C. auris with a focus on its implications for public health policy, particularly in the European and Balkan healthcare settings, where surveillance gaps and cross-border transmission risks remain pronounced. We analyze the key drivers of spread, including diagnostic misidentification, extensive antifungal resistance, and lapses in infection control, and evaluate the strain on surveillance and hospital preparedness. Effective mitigation is fundamentally dependent on implementing comprehensive, multi-faceted infection prevention and control strategies, guided by antifungal stewardship and rapid diagnostics. We conclude that addressing the C. auris threat requires an urgent, coordinated international and regional response focused on strengthening surveillance networks, standardizing diagnostic and infection prevention and control protocols, and fostering data sharing across borders to contain this resilient pathogen.",

To evaluate in vitro synergistic antifungal activity of betulinic acid (BA) combined with four azoles (itraconazole [ITR], voriconazole [VOR], posaconazole [POS], fluconazole [FLC]) against Aspergillus spp., Candida spp., Exophiala dermatitidis, and Cryptococcus neoformans. Per CLSI M27-A3/M38-A2, broth microdilution checkerboard assay determined BA's minimum inhibitory concentration (MIC) and synergy with azoles (n\u202f=\u202f110); flow cytometry measured intracellular reactive oxygen species (ROS) in fungi co-cultured with BA. BA alone had no antifungal activity, but showed synergy with specific azoles: BA/POS had 82.7% (43/52) synergy against Aspergillus spp., 95.2% (20/21) against E. dermatitidis, and 70% (7/10) against Candida auris (of 28 Candida spp., 28.6% synergy). BA/FLC had 55.6% (5/9) synergy against C. neoformans. Among the 110 strains, the synergy rates of BA with POS, ITR and VOR were 66.4, 10.9 and 2.7%, respectively; the BA-FLC synergy rate was 18.5% in 27 strains. BA/POS co-culture increased fungal ROS.

Rapid diagnostic testing is essential for C. auris infection control. This study aimed to assess the diagnostic performance of a direct polymerase chain reaction (PCR) assay compared with culture. The liquid Amies transport medium (Copan ESwab; Copan, Italy) and fungal enrichment broth were compared to determine the optimal media for the direct PCR assay. The diagnostic performance of the cobas omni Utility Channel Reagent Kit (Roche Diagnostics, Germany)-based direct PCR assay and culture was assessed against clinical outcomes. Sixty skin swab specimens were prospectively collected from intensive care unit patients at a university hospital in Korea. Each sample was tested in parallel using the Copan ESwab and Sabouraud dextrose (SD) broth. The direct PCR assay showed a sensitivity of 92.0%-96.0% and specificity of 85.7%-97.1% compared with a sensitivity of 76.0%-80.0% and specificity of 100% for culture across both media. For the direct PCR assay, the Copan ESwab showed a higher specificity, positive predictive value, and kappa value but lower sensitivity and negative predictive value than the SD broth. The discordant direct PCR assay-positive/reference standard-negative and PCR assay-positive/culture-negative cases showed significantly higher cycle threshold values than the concordant cases (p\u2009<\u20090.05).

While point mutations underlying antifungal resistance are well characterised, the contribution of structural genomic variation to antifungal responses remains poorly defined. Here, we integrate whole-genome sequencing, a genome-wide copy number variation (CNV) screen, electrophoretic karyotyping, and mutation-accumulation analyses to investigate the role of structural variation in antifungal susceptibility across a clinical cohort of C. auris isolates. We identify recurrent CNV hotspots, with segmental duplications representing a predominant mode of genome variation. Small duplications encompassing ERG11 arise at high frequency and frequently co-occur with drug resistance-associated ERG11 mutations, collectively enhancing azole resistance. In addition, large centromere-inclusive duplications of chromosome 1 generate supernumerary chromosomes, leading to paradoxical growth and reduced susceptibility to caspofungin, an echinocandin. At the population level, structural variants frequently arise in parallel to FKS1 mutations, suggesting multiple genetic mechanisms underlying reduced drug susceptibility. Together, our findings establish segmental duplication as a major, non-mutational driver of antifungal resistance, highlighting the need to consider structural genomic variation in both resistance surveillance and clinical susceptibility testing.",

In a study of infected and colonized patients conducted between 1/17/2023 and 11/30/2023 at our medical center in North-Central Florida, whole-genome sequence data were obtained for 43 C. auris isolates from 36 patients. Thirteen (30%) of the 43 isolates were from cultures collected as part of an investigation of a possible infection, with blood (7 isolates) being the most common source; 8 (62%) of the 13 patients with clinical infections died. Isolates were within either a Clade I monophyletic subclade associated with European and Middle Eastern strains (n = 27) or were from Florida subclades within C. auris Clade III (n = 16). In 7 instances, multiple isolates with virtually identical genetic profiles were isolated from the same patient at time intervals that ranged from 3 weeks to 7 months, with, in some instances, intervening negative cultures. All isolates were resistant to triazoles, albeit with resistance mutations at different nucleotide positions and within different genes for Clade I and Clade III isolates. One Clade I isolate was resistant to echinocandins. Data are consistent with a point-source C. auris outbreak involving a Clade I subclade of possible European origin, combined with multiple introductions and transmission of Clade III isolates from Florida.

A retrospective cohort study of 322 patients screened for C. auris between 2019 and 2025 at a tertiary care hospital in Riyadh. Patients were classified as C. auris positive (n = 107) or negative (n = 215). Baseline characteristics were compared using Mann-Whitney U and Fisher's exact tests. Logistic regression identified predictors of positivity. The C. auris positivity rate was 33.2%, declining from 58.1% in 2021 to 24.8% in 2024 as surveillance expanded. Positive patients were older (median 70 vs 59 years, P < .001) and had longer hospital stays (median 124 vs 21 days, P < .001). Cardiovascular, endocrine, renal, and hematological comorbidities were significantly more prevalent. Age (per 10 years: odds ratio [OR] 1.26, 95% confidence interval [CI] 1.12-1.42) and length of stay (per 30 days: OR 1.20, 95% CI 1.12-1.28) were the strongest continuous predictors. All-cause in-hospital mortality was higher in positive patients (51.4% vs 25.1%; OR 3.15, 95% CI 1.90-5.23, P < .001). Candida auris-positive patients exhibited advanced age, multimorbidity, prolonged hospitalization, and elevated all-cause mortality. These findings support targeted screening of high-risk populations in Gulf-region healthcare facilities.",

It's remarkable ability to evade host immune responses and persist in health care setting demands the development of effective immunotherapeutic strategies. In this study, a reverse vaccinology and immunoinformatics based approach was employed to design a novel chimeric multi-epitope vaccine targeting surface expose N-terminal domain of the agglutinin like protein involved in host pathogen interactions. High affinity B-cell and T-cell (MHC class I and II) epitopes were identified and screened based on antigenicity, allergenicity, toxicity and population coverage. Selected epitopes were assembled using optimized linkers (EAAAK, AAY and GPGPG) along with an adjuvant to enhance immunogenicity and structural stability. Physicochemical characterization, structural validation, molecular docking with human Toll-like receptor 4 (TLR4), Normal Mode Analysis (NMA), immune simulation, codon optimization and in silico cloning into the pET28a+ vector were performed to evaluate the vaccine construct. The selected epitopes demonstrated a global population coverage of 97.31%. the final vaccine construct was predicted to highly antigenic, non-allergenic, structurally stable and soluble. Molecular docking analysis revealed strong and stable interactions between the vaccine construct and human TLR4, with a binding energy of - 906.1\u00a0kcal/mol. Normal Mode Analysis further supported the structural stability of the vaccine receptor complex. Immune simulations predicted robust primary and secondary responses characterized by elevated IgG and IgM antibodies along with a Th1-skewed cytokine profile dominated by IFN-\u03b3 and IL-2 expression. Codon optimization and in-silico cloning indicated favorable translational efficiency in the pET28a+ expression system. The designed chimeric multi epitope vaccine demonstrated promising immunogenic, structural and receptor binding properties against Candida auris. These findings suggest that the proposed vaccine construct may serve as a potential candidate for further experimental validation and future development of effective immunotherapeutic interventions against multidrug- resistant fungal infections.",

They occur primarily in immunocompromised patients. The risk of Pneumocystis pneumonia and cryptococcosis has notably decreased for people living with HIV through the past two decades. Patients with diabetes or an autoimmune disease represent an increasing proportion of these cases. Mortality of invasive mycoses is still high, particularly in cases of candidemia and invasive aspergillosis. Azole-resistant Aspergillus spp. isolates remain rare in France and the proportion of resistant strains in cases of invasive candidiasis is stable. The emergence of Candida auris, which is associated with outbreaks in healthcare facilities, is closely monitored. Except for candidemia, investigation of predisposing genetic conditions should mainly be conducted when invasive mycosis occurs in patients without any clear risk factor.

The small number of antifungals available and the rapid emergence of resistance to azoles, echinocandins and polyenes underscore the urgent need to develop alternative therapeutic strategies with different mechanisms of action. Antifungal peptides (AFPs) have attracted increasing attention as promising candidates due to their broad-spectrum activity, multimodal mechanisms of action, and their low likelihood of resistance development. This review presents a thorough and holistic summary of the research on AFPs that target clinically significant drug-resistant fungi such as Candida auris, azole-resistant Candida albicans, and triazole-resistant Aspergillus fumigatus. We review the structural and physicochemical properties of AFPs and address their various antifungal mechanisms, which include membrane disruption, oxidative stress induction, and disruption of intracellular homeostasis, as well as biofilm inhibition. We further highlight an emerging computational-experimental pipeline to discover and optimize AFPs, combining sequence mining, machine learning-based screening, molecular docking, molecular dynamics simulations, and in vitro and in vivo validation. We also explore the major translational challenges, such as hemolytic toxicity, proteolytic instability, pharmacokinetic constraints, manufacturing complexity, regulatory concerns, and sustainable peptide manufacturing strategies, and discuss advanced delivery systems (e.g., liposomes, PLGA nanoparticles, chitosan-based systems, and hydrogels) to improve therapeutic efficacy and stability. In summary, this review proposes an integrated translational development framework that connects computational design, experimental validation, and delivery engineering, thereby positioning AFPs as a promising next-generation strategy in the fight against multidrug-resistant fungal infections.",

As a dominant genus within the phylum Actinomycetota, Streptomyces is widely recognized for its remarkable capacity to synthesize a diverse spectrum of clinically applicable antibiotics. Candida haemulonii, an emerging opportunistic fungal pathogen, has emerged as a typical multidrug-resistant species closely associated with outbreaks of nosocomial infections, posing a severe threat to clinical antifungal therapy. In this study, a novel strain designated as Streptomyces anandii NC-SA6 was isolated and systematically identified via gradient dilution method, multilocus sequence analysis (MLSA), coupled with comprehensive physiological and biochemical characterization assays. The optimal fermentation condition was optimized by controling a single variable method and measuring the diameter of the inhibition zone. The antimicrobial spectrum was tested against a panel of pathogenic strains, and the MIC value was measured by using broth microdilution. Finally, antifungal compounds were analyzed by combnining genome and metabolomic. We identified a strain with a spectrum antimicrobial activity against human pathogenic Candida species and Gram-positive bacteria. The optimal fermentation conditions are 4-day fermentation broth in No. 6 medium, and the MIC values of S. anandii NC-SA6 fermentation broth for Candida auris BJCA001 and Candida haemulonii 190070, the MIC50 values were 36.8 mg/ml and 18.4 mg/ml, respectively. Whole-genome sequencing analysis revealed the presence of 20 biosynthetic gene clusters (BGCs) responsible for secondary metabolite biosynthesis. Untargeted metabolomic analysis identified a total of 1703 metabolites. Functional annotation demonstrated that 43.5% of these metabolites were characterized bioactive compounds, including antimicrobial agents, antifungal agents, antitumor inhibitors, and other pharmaceutical molecules; the remaining 56.5% were uncharacterized metabolites, indicating the existence of potential secondary metabolites. Collectively, this integrated multi-omics study identified S. anandii NC-SA6 as a promising microbial resource for mining antifungal metabolites targeting multidrug-resistant C. haemulonii, highlighting its tremendous potential for the discovery and developmental research of novel antifungal agents.",

One of the alternative approaches to conventional therapies are currently based on essential oils (EOs) alone or in combination with antifungals. We aimed to evaluate the antifungal activity of Cinnamomum verum EO, alone and in combination with fluconazole, against reference and multidrug-resistant (MDR) Candida strains by in vitro and in vivo assays. The chemical composition of the EO was analyzed by gas chromatography-mass spectrometry. Antifungal activity was assessed by broth microdilution (minimum inhibitory concentration determination), while anti-adherence effects were evaluated using the microtitration with crystal violet. The fractional inhibitory concentration index and response surface approach were used to study synergistic interactions. The in vivo efficacy was assessed by tracking virulence factors, fungal load, and larval survival in Galleria mellonella model. The most significant phenylpropanoid components of the EO were (E)-cinnamaldehyde and eugenol. It demonstrated high antifungal activity and significantly decreased adherence to the inert substratum. The tested EO exhibited pharmacological synergy in combination with fluconazole, especially against fluconazole-resistant Candida auris strains. The optimized fluconazole-EO combination decreased fungal virulence and load, as well as G. mellonella larval mortality. C. verum EO exhibits strong anti-virulence and antifungal effects and increases fluconazole activity, indicating its potential as an adjuvant treatment against resistant Candida infections.",

A systematic review.\nAbstract: Candida auris is a widely distributed yeast that is considered a dangerous pathogen, with reported mortality rates ranging from 30% to 60%. This yeast shows a high level of resistance to several antifungal agents commonly used to treat systemic infections. The pathogen persists on contaminated surfaces, tolerates hospital-grade disinfectants, survives desiccation and spreads easily through direct or indirect contact. It has been reported on all five continents and is increasingly prevalent in Europe. To determine the distribution and antifungal susceptibility/resistance of Candida auris isolates identified in Europe until January 2025. This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Searches were conducted in EBSCOhost, MEDLINE/PubMed, Scopus and SciELO databases using the terms 'Candida auris' and 'Candidozyma auris', combined with the name of each European country. It was limited to English or Spanish articles published until 31 January 2025, excluding reviews, meta-analyses and book chapters. Ninety-one articles reporting antifungal susceptibility were retrieved, covering 2191 clinical isolates of C.\u2009auris from 16 countries. Most isolates were from Spain (n\u2009=\u2009886, 40.44%), Italy (n\u2009=\u2009553, 25.24%), Greece (n\u2009=\u2009214, 9.77%), the United Kingdom (n\u2009=\u2009182, 8.31%) and Russia (n\u2009=\u2009108, 4.93%), accounting for 88.68% of cases. The remaining 248 isolates (11.32%) were reported across 11 other countries. Fluconazole resistance was found in 90.51% (1555/1718), while resistance to amphotericin B and echinocandins was 13.17% (223/1693) and 4.57% (76/1693), respectively. Candida auris has been predominantly detected in Southern Europe, where the majority of clinical isolates exhibit resistance to fluconazole. Consensus is essential for timely diagnosis, targeted treatment and infection control to prevent its spread. New therapeutic options must be explored to manage Candida auris.",

Candida auris) is an emerging multidrug-resistant yeast of growing clinical and environmental concern. Despite its increasing detection in healthcare settings worldwide, environmental evidence remains scarce. This study presents the first molecular detection of C. auris DNA in surface waters of T\u00fcrkiye, within the Ramsar-protected Gediz Delta, as part of the national One Health Surveillance Framework. A total of 80 surface-water samples were collected from five wetland ecosystems Tuz Lake, Kulu Lake, G\u00f6ksu Delta (Akg\u00f6l and Paradeniz Lagoons), K\u0131z\u0131l\u0131rmak Delta, and Gediz Delta. Physicochemical parameters; temperature, pH, and salinity were recorded in situ using a multi parameter sensor. Environmental DNA was extracted from 2\u00a0L of 0.22\u00a0\u00b5m Sterivex-filtered water and analyzed via qPCR using C. auris-specific (CauF/CauR) and Candida-genus (CauRelF/CauRelR) primer sets. Yeast isolation was performed on CHROMagar\u2122 Candida Plus, and identification was achieved by MALDI-TOF MS. C. auris DNA was detected in one sample (1.25%), specifically from the Gediz Delta (Sample No. 5651, 38.523\u00b0\u00a0N, 26.892\u00b0\u00a0E), with Ct values 33.8-37.2 confirmed by sequencing. Broader Candida genus signals were observed in 24% of samples. Culture-based analyses yielded no viable C. auris, but 15 yeast isolates were identified, mainly Pichia kudriavzevii (Candida krusei), C. albicans, and Nakaseomyces glabratus (Candida glabrata). The culture-negative yet qPCR-positive finding indicates that C. auris DNA likely persists in aquatic environments as non-viable or residual material. This finding provides early molecular evidence of environmental dissemination and underscores the need for viability assays, culture-based isolation, and metagenomic monitoring integrated within One Health surveillance programmes.",

This review consolidates recent pharmacological developments in this regard, focusing on mechanistic insights and late-stage therapeutics. Novel agents demonstrate activity against multidrug- and pan-resistant isolates via distinct mechanisms of action and enhanced specific binding to CYP51. Repositioned drugs, host-defense peptides, and quorum-sensing modulators also expand the treatable spectrum, particularly for biofilm-associated and device-related infections. Concurrently, artificial intelligence (AI)-guided discovery, nanocarrier-enabled delivery, and multi-omics profiling are greatly accelerating target identification and enhancing the drug metabolism of small-molecule fragments. The emerging combined approaches mark a transition towards mechanism-based antifungal development to combat the increasing clinical burden posed by C. auris. Ongoing integration of precision diagnostics, pharmacodynamic optimization, and novel discovery platforms will be key to translating these advances into durable, real-world therapeutic solutions.",
        "42475389": "ID: 42475389\nTitle: An emergent biofilm program from inactivation of Candida albicans master regulators Efg1 and Ndt80.\nAbstract: Biofilm formation by the fungus Candida albicans is a central virulence trait that enables colonization of implanted medical devices and mucosal surfaces. Biofilm formation reflects a complex regulatory network, and depends upon multiple master regulators that include transcription factors Efg1 and Ndt80. It is well established that efg1\u0394/\u0394 and ndt80\u0394/\u0394 single gene mutants are defective in biofilm formation. We report here that an efg1\u0394/\u0394 ndt80\u0394/\u0394 double mutant of reference strain SC5314 is able to form a robust biofilm in vitro and in vivo. We refer to the efg1\u0394/\u0394 ndt80\u0394/\u0394 biofilm as an emergent biofilm because this phenotype could not have been predicted from the phenotypes of efg1\u0394/\u0394 or ndt80\u0394/\u0394 single gene mutants. In four additional strain backgrounds, efg1\u0394/\u0394 ndt80\u0394/\u0394 mutants do not form biofilms, but in all strain backgrounds the efg1\u0394/\u0394 ndt80\u0394/\u0394 mutants can form filamentous cells, which are components of biofilms. Emergent biofilm formation is especially pronounced in YPD\u2009+\u2009FBS medium at 30\u00b0C, and RNA-seq under those conditions reveals altered expression in the efg1\u0394/\u0394 ndt80\u0394/\u0394 double mutant of biofilm-related genes: upregulation of BCR1, UME6, and HGC1, and downregulation of ALS3, BRG1, and HWP1. These gene expression changes suggest that the emergent biofilm program is partially distinct from the conventional biofilm program. This inference is supported by functional analysis: emergent biofilm formation is independent of Brg1, Rob1, Tec1, and Wor3, all of which have positive roles in conventional biofilm formation. Emergent biofilm formation depends upon the hyphal cyclin Hgc1, the biofilm transcription factors Bcr1 and Ume6, and the Bcr1/Ume6-activated adhesin gene FLO9. The seemingly simple emergent biofilm program may represent a primordial surface colonization strategy.",

To clarify the phenotypic characteristics and toxigenic divergence of the pathogen, 70 strains from major peanut-growing regions were subjected to morphological characterization, phylogenetic analysis, elsinochrome (ESC) quantification, and phytotoxicity assessment. Based on colony color, the strains were divided into five morphological groups (Group A-E), with the dark red pigmented Group D being dominant (50%). Growth rates varied among strains, with the coefficient of variation within each morphological group ranging from 10% to 25%, but no distinct pattern was observed across groups. All isolates were identified as E. arachidis and resolved within a species-level clade based on ITS and TEF1-\u03b1 phylogenetic analyses. ESC quantification revealed a significant correlation between colony color and toxin accumulation, with coral red and dark red strains (Groups A and D) accumulating higher ESC levels. Phytotoxicity assays demonstrated a significant positive correlation between lesion area and ESC accumulation (r\u202f=\u202f0.921, P\u202f<\u202f0.01). This study systematically characterized the intraspecific phenotypic differentiation of E. arachidis in China for the first time, establishing a correlation between pathogenic intensity, colony color, and ESC synthesis capacity. Furthermore, colony color was proposed as a visual phenotypic indicator for the rapid identification of highly virulent strains, and ESC accumulation was identified as the key metabolic process underlying phytotoxicity differentiation. These findings enhanced the understanding of population differentiation in E. arachidis and provide a theoretical basis for elucidating disease outbreak mechanisms and developing targeted control strategies.",

This study provides an integrated analysis of the morphology, infection biology, molecular identity, and associated fungal microbiome of P. polysora. Microscopic investigations using stereoscopic, light, and scanning electron microscopy revealed detailed spore morphology and infection structures, including appressoria formation and intercellular colonization. Notably, hyphal anastomosis was observed, suggesting a potential mechanism for genetic exchange and pathogen adaptability. Molecular identification using basidiomycete-specific ITS primers (ITS1-F and ITS4-B) confirmed pathogen identity, supported by phylogenetic analysis. These findings significantly enhance our understanding of SCR pathogenesis and provide new insights into the biology and adaptability of P. polysora, opening new avenues for research on pathogen evolution and the development of effective strategies for disease management.",

In this perspective paper we explore the untapped potential of WBE as a catalyst for infectious disease surveillance and as a One Health epidemiological tool, and the future horizons and innovative applications of WBE. It is clear that WBE will address a growing number of pathogens of concern to human health, such as avian influenza viruses, mpox, enterovirus D68, Candida auris, and antimicrobial resistance. In addition, it will contribute to epidemic intelligence by monitoring mass gathering events, and by predictive modeling and forecasting in combination with artificial intelligence to mitigate and prevent infectious diseases from reaching the highest level of clinical complexity. We believe that the maximum performance and complete institutional integration into public health of WBE is yet to be realized on a global scale.",

C. tropicalis isolates from patients with bloodstream infections at West China Hospital of Sichuan University (2018-2023) were collected and identified by chromogenic culture and MALDI-TOF MS. Using Clinical and Laboratory Standards Institute broth microdilution (BMD) method as the reference standard, we compared the performance of the Sensititre YeastOne chromogenic antifungal susceptibility testing and optimized MS-AFST based on the minimum profile change concentration (MPCC). All the 41 isolates were confirmed as C. tropicalis, which showed an azole resistance rate of 36.59% and a proportion of non-wild-type strain of 68.29% with high cross-resistance to azoles. The categorical agreement (CA) and essential agreement (EA) between Sensititre YeastOne and CLSI BMD were both 100%, and their minimum inhibitory concentrations were highly correlated. The MPCC-based MS-AFST enabled rapid detection of fluconazole-resistant phenotype of C. tropicalis within approximately 3 h, demonstrating a CA of 92.68% and an EA of 90.24% both in comparison with the CLSI BMD reference method and Sensititre YeastOne; very major error\\discrepancy occurred in two strains, and minor error\\discrepancy occurred in one strain. MPCC-based MS-AFST enables rapid, reliable detection of fluconazole resistance in C. tropicalis with good agreement with the reference methods.

These challenges are intensified by the difficulty of accurately identifying this species, particularly in settings with limited laboratory resources. This difficulty arises because C. auris is closely related to other yeast species, such as those within the Candida haemulonii complex. Although we previously demonstrated that near-infrared spectroscopy (NIRS) combined with multivariate analysis can discriminate C. auris from C. haemulonii stricto sensu, its performance against other clinically important yeasts had not been evaluated. In this study, we assessed NIRS coupled with different multivariate analytical techniques as a tool for distinguishing C. auris from C. haemulonii, C. albicans, C. tropicalis, C. parapsilosis, Nakaseomyces glabrata (formerly C. glabrata), and Pichia kudriavzevii (formerly C. krusei). Each of the seven species was cultured on fifteen Sabouraud Dextrose agar plates at 37 \u00b0C. After 72 h, three isolated colonies per plate (45 colonies per species) were subjected to Fourier-transform NIR analysis, resulting in a total of 315 spectra. The spectra were preprocessed and analyzed using principal component analysis (PCA), successive projections algorithm (SPA), genetic algorithm (GA), and linear discriminant analysis (LDA) to construct classification models. The combination of PCA, SPA, and GA with LDA achieved 100% sensitivity, specificity, and accuracy. These findings demonstrate that NIRS coupled with multivariate analysis can reliably differentiate C. auris from other medically important yeasts. The models also showed strong discriminatory capacity among the most prevalent pathogenic yeast species, reinforcing the promise of this approach as a rapid diagnostic tool for overcoming current identification challenges.",

Although strain CBS138 has served as the principal model for genetic and functional studies, accumulating evidence indicates substantial intraspecies diversity that may shape virulence, immune interactions and stress adaptation. In particular, the widely used clinical isolate BG2 differs from CBS138 in genome structure, adhesin regulation and macrophage survival, yet the extent to which these differences are reflected at the fungal cell surface remains unknown. Here, we present a comparative characterization of the surface-exposed proteomes (surfaceomes) of CBS138 and BG2 across three biologically relevant growth conditions: YPD-grown yeast-like cells, RPMI-cultured planktonic aggregates and RPMI-formed biofilms. Using trypsin shaving combined with LC-MS/MS, we identified pronounced strain- and condition-dependent differences in surface protein composition, encompassing adhesins, yapsin proteases and selected moonlighting proteins. Whereas CBS138 showed greater representation of adhesion- and interaction-related surface proteins, BG2 preferentially displayed proteins associated with cell-wall architecture and remodelling, consistent with distinct surface-mediated adaptive strategies. Transmission electron microscopy revealed condition-dependent differences in cell-wall thickness in both strains, with BG2 displaying a broader range of values and the highest thickness under biofilm conditions, providing structural context for variation in protease accessibility and surface-protein detectability. Collectively, our findings highlight substantial surfaceome plasticity in C. glabrata and underscore the importance of considering intraspecies diversity when interpreting host-pathogen interactions and fungal virulence pathways.",

We developed and validated a Fourier-transform infrared (FTIR) spectroscopy-based classifier (AurisC2-ID) to distinguish clade II from non-clade II C. auris isolates. In total, 106 C. auris isolates col-lected from 14 Korean hospitals, representing clades I and II, and 10 reference isolates from the Centers for Disease Control and Prevention and Food and Drug Administration Antimicrobial Resistance Isolate Bank, representing four clades (I-IV), were analyzed using FTIR spectroscopy (IR Biotyper; Bruker Daltonics, Bremen, Germany) as the training set for classifier development. The classifier was constructed using an artificial neural network al-gorithm following principal component analysis and was validated using 87 additional clini-cal isolates collected from nine Korean hospitals. The training set spectra showed clear separation between clade II and non-clade II isolates, with minor overlap between the two groups. During validation, all 31 clade II isolates were correctly classified as clade II, and the remaining 56 clade I isolates as non-clade II. These results demonstrate that AurisC2-ID can accurately distinguish clade II from non-clade II C. auris isolates and may serve as a useful tool for infection control in Korea.",

We conducted a retrospective observational study in a high-complexity hospital in Ibagu\u00e9 (Tolima, Colombia) from 2014 to 2024, integrating two institutional data sources: administrative/clinical records and the microbiology laboratory database (WHONET). Species identification relied on culture and VITEK, and antifungal susceptibility was interpreted using criteria from the Clinical and Laboratory Standards Institute (CLSI) and the European Committee on Antimicrobial Susceptibility Testing (EUCAST). We summarized data using frequencies/proportions and medians (IQR), explored patterns with multiple correspondence analysis (MCA), and estimated associations with candidemia using penalized multivariable logistic regression due to low event frequency. We identified 987 candidiasis episodes and 776 fungal isolates, of which 314 were Candida (40.46%). Mucocutaneous disease predominated (vulvovaginal 50.7%; oropharyngeal 24.3%), while candidemia represented 2.0% of episodes. Among isolates, Candida albicans was most frequent (58.9%), followed by C. parapsilosis (16.6%), C. tropicalis (12.1%), and Nakaseomyces glabratus (6.4%); Candida auris was detected once. In exploratory clinical/administrative models, clinically recorded candidemia showed associations with invasive devices (OR 5.54, 95% CI 2.01-15.64), recent surgery (OR 7.11, 95% CI 1.20-30.88) and tumor (OR 19.88, 95% CI 3.14-97.51). Susceptibility data were available for 196/314 isolates (62.4%); echinocandin activity was high, whereas azole susceptibility was more variable.

Analysis of 80 peer-reviewed studies reveals five principal findings: (1) C. auris exhibits clade-dependent geographic distribution and resistance profiles-Clade I (South Asia) and Clade III show fluconazole resistance exceeding 90%, whereas Clade IV exhibits 44% resistance; echinocandin resistance varies significantly by clade and no resistance was detected in certain clades; amphotericin B resistance varies from no detected resistance to 46% depending on clade; and pan-resistant strains have emerged; (2) biofilm-associated C. auris cells (sessile cells) exhibit MBECs 2- to 4,119-fold higher than planktonic MICs, representing a major driver of persistent colonization; (3) novel antifungal agents, including ibrexafungerp, manogepix (the active moiety of fosmanogepix), and rezafungin, demonstrate promising in vitro activity against C. auris, with manogepix showing the highest overall antibiofilm activity (geometric mean MBEC of 5.9 \u03bcg/mL) and ibrexafungerp demonstrating superior activity against Clade IV biofilms; (4) a tiered infection prevention and control (IPC) framework-integrating universal screening, contact precautions, and environmental decontamination-has been associated with reduced transmission rates in outbreak settings; and (5) climate change and global warming may have contributed to the emergence of C. auris through thermal adaptation of environmental fungal species.

Eighteen extracts demonstrated significant antifungal and antibiofilm activity, particularly from species in the Fabaceae, Myrtaceae, and Celastraceae families. Extracts from Hymenaea stigonocarpa notably inhibited the yeast-to-hyphae transition, a key virulence factor. Using molecular networking (GNPS) and in silico tools (SIRIUS), 60 putative compounds were annotated, including xanthones, flavonoids and triterpenoids, with selected candidates showing favorable binding profiles in molecular docking analyses.

Data from T\u00fcrkiye remains limited. This retrospective observational study evaluated bacterial and fungal isolates from adult ICU patients at a tertiary hospital from 2016 to 2025. Microorganisms were identified, and antimicrobial susceptibility testing was performed using standardized methods. Resistance patterns were compared between the pre-pandemic (January 2016-February 2020) and post-pandemic (March 2020-May 2025) periods. A total of 2666 patients and 5433 isolates were analyzed. Gram-negative pathogens showed marked increases in resistance: carbapenem and colistin resistance in Klebsiella pneumoniae were significantly higher in the post-pandemic period (69.6% vs. 44.4% and 60.5% vs. 22.5%, respectively; p < 0.001). Resistance rates to multiple antimicrobial agents also increased in Acinetobacter baumannii and Pseudomonas aeruginosa (p < 0.05). Among Gram-positive bacteria, vancomycin-resistant Enterococcus faecium increased from 10% to 47.1%. Candida auris emerged only in the post-pandemic period, showing high resistance to fluconazole (75%) and amphotericin B (36.7%). Significant differences in AMR patterns were observed between the pre- and post-pandemic periods in this ICU population. Higher resistance rates were observed among several clinically important bacterial pathogens, and Candida auris emerged exclusively during the post-pandemic period. Given the study's observational design, these findings should be interpreted as temporal associations rather than evidence of a causal effect of the COVID-19 pandemic. Continued antimicrobial stewardship and infection-control measures remain essential to address the growing burden of AMR.",

Whole-genome sequencing studies have demonstrated the existence of genetically distinct clades that differ in geographical distribution, antifungal resistance patterns, virulence traits, and outbreak potential. Objectives: This study aimed to evaluate the performance of the ClaID clade identification PCR system among clinical Candida auris isolates collected in \u0130stanbul, T\u00fcrkiye, and to investigate the clade-associated molecular profiles of circulating isolates. Methods: Forty-four clinical C. auris isolates were analysed using the auris universal sequence (AUS) assay and clade-specific sequence assays (CSS1-CSS5). PCR amplification results were interpreted according to the ClaID framework. Results: AUS amplification was detected in 41/44 isolates (93.2%). CSS1 amplification was observed in 39/44 isolates (88.6%), indicating a predominance of Clade I-associated molecular profiles within this regional \u0130stanbul isolate collection. No amplification was detected using CSS2, CSS3, CSS4, or CSS5 assays. Three isolates were AUS-negative and five isolates did not yield CSS1 amplification despite repeated testing. Conclusions: The findings suggest that the majority of analyzed clinical isolates from \u0130stanbul exhibited Clade I-associated molecular profiles rather than definitive WGS-confirmed clade assignments. This study provides one of the first field evaluations of the ClaID system in a Turkish clinical isolate collection and contributes regional molecular epidemiological data regarding PCR-based clade-associated profiles of C. auris in T\u00fcrkiye.",

We conducted a retrospective cohort study of adult patients with candidaemia who received antifungal therapy at a tertiary hospital in Seoul, Republic of Korea, from January 2023 to December 2024, comparing C. auris with other Candida species. Confounding was addressed by inverse probability of treatment weighting (IPTW) using a five-covariate propensity score (age, Charlson Comorbidity Index, septic shock, ICU admission at antifungal initiation, and concomitant Gram-negative infection). Among 423 patients, C. auris accounted for 6.9% of cases and was uniformly fluconazole non-susceptible, with frequent high-level caspofungin resistance but preserved micafungin and anidulafungin susceptibility. Patients with C. auris were older, with greater comorbidity and more frequent ICU admission at antifungal initiation. After IPTW adjustment, C. auris was not associated with higher 30-day mortality, the primary outcome (adjusted hazard ratio 0.59, 95% CI 0.26-1.32); the wide confidence interval indicates limited precision rather than equivalence, and results were directionally consistent for 90-day and in-hospital mortality and across sensitivity analyses that varied both the comparison cohort and the analytic method. Residual confounding by unmeasured illness severity and limited precision preclude concluding equivalence.

Comparative clinical data on first-line echinocandins-micafungin and anidulafungin-in C. auris candidemia remain limited. This retrospective cohort study compared clinical outcomes of micafungin and anidulafungin in adult patients with C. auris candidemia treated between January 2024 and December 2025 at three affiliated hospital campuses in Istanbul, T\u00fcrkiye. Propensity score matching (PSM) using a 1:1 nearest-neighbor algorithm was performed to balance baseline characteristics. Outcomes included 30-day (primary) and 14-day all-cause mortality, microbiological response, end-of-therapy (EOT) response, relapse, and drug-induced liver injury assessed by the Roussel Uclaf Causality Assessment Method (RUCAM). Among 154 included patients (micafungin, n = 94; anidulafungin, n = 60), no echinocandin resistance was detected.

This study aimed to evaluate the antifungal efficacy of hypocrellin B (HB)-mediated antimicrobial photodynamic therapy (aPDT) against biofilms formed by various strains of C. albicans, including standard, azole-sensitive, and azole-resistant strains. The effects of HB-aPDT on the viability, metabolic activity, and biomass of C. albicans biofilms were assessed using colony-forming unit (CFU) assays, XTT reduction assays, and crystal violet (CV) staining. Confocal laser scanning microscopy (CLSM) was used to observe changes in cell membrane integrity. The generation of reactive oxygen species (ROS) was analyzed using flow cytometry, and the impact on gene expression was examined using quantitative real-time PCR (qRT-PCR). HB-aPDT significantly reduced the survival of C. albicans biofilms in a dose- and light-dependent manner. CLSM revealed photodamage to cell membranes post-treatment, and an increased presence of ROS was observed in the treated biofilms. Gene expression analysis showed downregulation of virulence-related and ergosterol biosynthesis genes, indicating a potential disruption of key pathways in fungal pathogenesis. HB-mediated aPDT effectively reduced the viability and disrupted the structural integrity of C. albicans biofilms, including those resistant to conventional antifungals. This study highlights the potential of HB-aPDT as an innovative approach for managing drug-resistant Candida infections and offers a promising alternative to traditional antifungal therapies.",

While traditional risk factors such as tobacco and alcohol are well established, increasing evidence highlights the role of the oral microbiome in carcinogenesis. Among microbial species, Candida albicans (C. albicans) has emerged as a potential contributor to tumor-promoting processes. Clinical studies consistently report increased fungal colonization in oral potentially malignant disorders and OSCC, with associations to disease severity and recurrence. Mechanistically, C. albicans contributes to carcinogenesis through acetaldehyde production, chronic inflammation, oxidative stress, epithelial signaling modulation, and extracellular vesicle (EV)-mediated communication. These pathways promote tumor microenvironment remodeling and epithelial transformation. However, conflicting evidence exists regarding causality, suggesting that fungal colonization may also result from tumor-associated ecological changes.

As an opportunistic pathogen that commonly resides in the intestinal microbiota, C. albicans can subsequently translocate across the intestinal barrier and cause intra-abdominal infections. To investigate this process, a murine model of peritoneal C. albicans infection was established, in which sodium new houttuyfonate was administered for therapeutic evaluation. The therapeutic potential of sodium new houttuyfonate against abdominal C. albicans infection was evaluated through assessment of immune cell composition, peritoneal macrophage polarization, tissue fungal burden, and histopathological features. The molecular mechanisms of sodium new houttuyfonate therapy were also investigated with cellular experiments, including colony counting, real-time quantitative PCR, Western blotting, and the detection of reactive oxygen species (ROS) in RAW264.7 macrophages. Our results revealed that sodium new houttuyfonate exerts a dual anti-infective effect through its fungicidal activity and via the immunomodulation of immunoinflammatory states. Sodium new houttuyfonate also stimulates cytokine production (e.g., IL-1\u03b2, IL-6, IL-10, TNF-\u03b1, and MCP-1) via the TLR2/p38/NF-\u03baB pathway and promotes the release of ROS and nitric oxide. Overall, these findings highlight the potential of exogenous sodium new houttuyfonate as a therapeutic option for abdominal C. albicans infection.",

In this study, three clinical C. auris strains (namely C. auris strain 01, C. auris strain 03, and C. auris strain 13) with distinct origins were characterized to investigate their phenotypic variations and mechanisms of azole resistance. Comprehensive profiling revealed significant inter-strain differences in biofilm formation, cell surface hydrophobicity, adhesion capacity, and phospholipase activity. Testing for antifungal susceptibility showed that the three clinical strains exhibited different minimum inhibitory concentrations for multiple azoles (fluconazole, voriconazole, and itraconazole) and echinocandins (anidulafungin and micafungin). Sequencing identified Y132F mutations in the ERG11 gene of the three clinical strains. Mechanistic investigations demonstrated that fluconazole exposure significantly upregulated the expression of efflux pump genes (CDR1 and CDR2) and the genes encoding their transcriptional regulators (MDR1 and TAC1b). In a murine skin colonization model, comparing data from the standard strain C. auris strain CBS12766 and clinical strains of C. auris strain 03 and C. auris strain 13 exhibited a significantly higher fungal burden of tissue, whereas strain C. auris strain 01 showed an intermediate level. Host immunity response analysis revealed that expression of the IL-1\u03b2 gene was significantly elevated in C. auris strain CBS12766-infected mice, while expression of IL-6 and CXCL-1 genes was predominantly increased in the C. auris strain 01, with TNF-\u03b1 gene expression levels being comparable across all strains. Histopathological examination confirmed local infiltration of inflammatory cells and mild epidermal edema, indicating active host immune engagement. Overall, our findings highlighted substantial phenotypic heterogeneity, different colonization capacities, and differences in expression of inflammatory cytokines among the C. auris strains. Further investigations into fluconazole-response mechanisms identified enhanced efflux pump activity, along with ERG11 gene Y132F mutations and transcription factor modulation among these clinical strains.",

We aimed to characterize Candida viswanathii isolates recovered in the setting of panel-negative candidemia and to assess the contribution of an integrated diagnostic workflow. We investigated seven C. viswanathii isolates overall, including three recovered at our institution from blood, urine, and bronchoalveolar lavage of a NICU patient, as well as four bloodstream isolates from a second pediatric center included for comparison. Isolates were analyzed by culture and microscopy, three MALDI-TOF MS platforms, internal transcribed spacer sequencing, Fourier transform infrared (FTIR) spectroscopy and antifungal susceptibility testing. C. viswanathii was repeatedly recovered from blood, urine and bronchoalveolar lavage, while the FilmArray BCID2 panel remained negative. All MALDI-TOF MS systems with updated databases correctly identified the yeast at the species level; identification was confirmed by sequencing. Fourier transform infrared analysis showed clustering of clinical isolates and clearly separated C. viswanathii from related Candida species. All isolates exhibited low MICs to echinocandins and amphotericin B as well as moderately elevated fluconazole MICs (2-4 mg/L). This study supports the use of explicit diagnostic algorithms for rare fungal pathogens in yeast-positive, syndromic panel-negative blood cultures. In this setting, updated MALDI-TOF MS libraries and FTIR spectroscopy may provide useful adjunctive support for the recognition and phenotypic discrimination of atypical yeasts within an integrated laboratory workflow.",

Although antifungal therapy is standard, the host pathways shaping vascular responses-particularly the Notch signaling pathway (NSP)-are not well characterized in this context. In addition, the potential influence of the prostaglandin pathway on vascular NSP-related responses during infection remains unclear. In this study, a rat model of central venous catheter-associated C. albicans infection was used to evaluate microbiological outcomes and vascular NSP-related protein expression. Immunohistochemical analyses were performed to assess Candida immunostaining alongside the expression of Notch receptors (Notch1-3) and ligands (DLL1/4, Jagged1/2) in vascular tissues. Experimental groups included sham, infected control, antifungal-treated (fluconazole, caspofungin, liposomal amphotericin B), and prostaglandin pathway-intervention groups (sulprostone and sulprostone followed by indomethacin). C. albicans infection was associated with higher vascular NSP-related protein expression compared with sham animals. Antifungal-treated groups showed lower NSP-related protein expression, while fungicidal agents were associated with absence of fungal growth in catheter and kidney cultures. In the sulprostone-indomethacin-treated group, NSP-related protein expression levels were lower than those in the sulprostone-treated group despite persistent fungal burden. In conclusion, central venous catheter-associated C. albicans infection was associated with altered vascular NSP-related protein expression. Differences in NSP-related protein expression patterns were observed across antifungal- and prostaglandin pathway-intervention groups. These findings are descriptive and do not allow causal inference but may provide a basis for future studies exploring the role of NSP in vascular responses to C. albicans infection.",

In pathogenic fungi, it dynamically governs morphogenesis, stress adaptation, and antifungal drug resistance. Using high-resolution mass spectrometry-based phosphoproteomics, researchers have systematically mapped phosphorylation dynamics in WHO-priority pathogens-Candida albicans, Aspergillus fumigatus, Cryptococcus neoformans, and the multidrug-resistant Candidozyma auris (formerly Candida auris). These studies reveal that thousands of phosphorylation events are coordinately reprogrammed in response to antifungal drug exposure, host-derived oxidative stress, and temperature shifts. Integration of available datasets suggests a \"conserved-core/divergent-output\" organization. Shared kinase hubs like cAMP-PKA, HOG-MAPK and calcineurin are broadly conserved across species. Downstream substrate networks, however, have diverged, producing distinct virulence outputs in each pathogen. Notably, C. auris remains completely uncharacterized at the phosphoproteomic level. This review provides a comprehensive synthesis of the phosphoproteomic landscape across these pathogens, and discusses how phosphoproteomic data are guiding the rational prioritization of kinases and phosphatases as next-generation antifungal drug targets-with direct implications for clinical surveillance and public health.",

This study investigated the in vitro antimicrobial and antibiofilm potential of endophytic mediated-synthesized silver nanoparticles (AgNPs). Methods: An endophytic bacterium was isolated from the medicinal plant Commiphora gileadensis in Saudi Arabia and identified as Bacillus subtilis CG1 through 16S rRNA gene sequencing. The bacterium was utilized for the green synthesis of AgNPs, as confirmed by Ultraviolet-visible (UV-Vis) spectroscopy. AgNPs characterization was done using Fourier-transform infrared (FTIR) spectroscopy, Transmission and scanning electron microscopy (TEM and SEM), energy-dispersive X-ray spectroscopy (EDX), and dynamic light scattering (DLS). The antimicrobial efficacy of the fabricated AgNPs was tested against eight clinically relevant pathogens using standard in vitro assays such as the agar disk diffusion method, minimum inhibitory concentration (MIC), minimum bactericidal and fungicidal concentrations (MBC and MFC). Additionally, AgNPs were tested for antibiofilm activity against P. aeruginosa and S. epidermidis. Tested pathogens included Methicillin-Resistant Staphylococcus aureus (MRSA), Staphylococcus epidermidis, Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli, Candida auris, Candida albicans, and Candida tropicalis. The antibiofilm efficacy was tested using the Crystal violet assay. Results: UV-Vis spectroscopy confirmed AgNP formation with a characteristic absorption peak at 412 nm. FTIR analysis identified the presence of hydroxyl, nitrile, and alkyne functional groups, which are involved in nanoparticle reduction and stabilization. TEM and SEM revealed predominantly spherical AgNPs with sizes ranging from 17 to 72 nm, while EDX confirmed silver as the major elemental component. DLS analysis showed a Z-average particle size of 113.9 \u00b1 67.75 nm and a zeta potential of -24.2 mV. The synthesized AgNPs exhibited concentration-dependent antimicrobial activity, producing inhibition zones of 10-20 mm at 240 \u00b5g/mL. MIC values ranged from 6.25 to 25 \u00b5g/mL, whereas MBC and MFC values ranged from 6.25 to 50 \u00b5g/mL and 25 to 100 \u00b5g/mL, respectively. Moreover, bacterial growth kinetics analysis demonstrated a concentration-dependent inhibition of growth by AgNPs at MIC and sub-MIC concentrations.

In this study, we report the synthesis, characterization, and biological evaluation of a guar gum-quercetin bioconjugate designed to improve the practical applicability of quercetin through covalent conjugation with a biocompatible polysaccharide scaffold and a cystamine-based disulfide linker. The formation of the GG-Cys-Quer conjugate was supported by FTIR, 1H/13C NMR, CHNS elemental analysis, degree-of-substitution estimation, SEM, and TGA. The conjugate showed potent antifungal activity against five clinical C. auris isolates, with MIC and MFC values ranging from 0.030 to 0.245 \u00b5g mL-1 and 0.123 to 0.488 \u00b5g mL-1, respectively. Against the resistant isolate MRL6057, GG-Cys-Quer showed an MIC of 0.245 \u00b5g mL-1, whereas caspofungin showed an MIC of 4.0 \u00b5g mL-1 under the same assay conditions. Mechanistic studies showed increased intracellular ROS accumulation, loss of mitochondrial membrane potential, and apoptosis-associated changes, as confirmed by Annexin V/PI staining, with a concentration-dependent increase in late apoptotic/necrotic cell populations at higher exposure levels. Ultrastructural analysis further revealed membrane deformation, pore formation, and cellular collapse, supporting severe fungal cell damage following treatment. In mammalian L929 fibroblasts, GG-Cys-Quer maintained >85% cell viability at MFC-level exposure, indicating preliminary in vitro cytocompatibility. Overall, these findings demonstrate that GG-Cys-Quer is a structurally characterized guar gum-quercetin conjugate with strong in vitro antifungal activity against C. auris and a mechanism involving oxidative stress, mitochondrial dysfunction, and apoptosis-associated fungal cell death. Further side-by-side studies with free quercetin, linker controls, guar gum controls, and in vivo models are required to define the specific contribution of conjugation and assess translational potential.",

Hospital-acquired infections (HAIs) frequently manifest as device-related biofilms that exhibit enhanced tolerance to conventional therapies contributing to antimicrobial resistance. Polymicrobial biofilms involving Candida and Staphylococcus species are a major cause of persistent nosocomial infections. However, while the synergism between Candida albicans and Staphylococcus aureus is well-characterized, the interactions involving non-albicans Candida remain poorly understood.Hypothesis/Gap Statement. The specific interactions between Candida parapsilosis and S. aureus were entirely unknown, although it was broadly assumed they would be synergistic in nature, mirroring known Candida-Staphylococcus models.Aim. This study investigated the interspecies dynamics between C. parapsilosis and S. aureus within a mixed biofilm context.Methodology. C. parapsilosis secretome fractions were isolated and screened against methicillin-sensitive (MSSA) and methicillin-resistant (MRSA) S. aureus strains. Their effects on biofilm formation, primary attachment, planktonic growth and eradication were evaluated under varying glucose concentrations, followed by transcriptomic analysis of treated staphylococcal cells.Results. We report the discovery of a small (<10\u2009kDa), heat-stable fungal-secreted factor that significantly inhibits the maturation of MSSA biofilms and disperses preformed biomass without affecting primary attachment or planktonic growth, although MRSA strains remained recalcitrant. This antagonism is strictly glucose-dependent; the inhibitory effect is potent in 0.2% glucose but is abolished in both 0.5 and 1.0%\u2009glucose. Transcriptome analysis revealed that the fungal secretome triggers a pleiotropic 'Metabolic Trap' in S. aureus, characterized by the downregulation of the glycolytic pathway (e.g. tpiA, gapA) and a failure to induce critical-acid-tolerance systems, including the arginine deiminase and urease operons. This metabolic reprogramming maintains a near-neutral local pH (5.8-6), which in turn provides an optimal environment for the observed upregulation of staphylococcal nuclease (nuc) ultimately degrading the extracellular matrix and preventing the development of a mature biofilm architecture.Conclusion. We propose that the C. parapsilosis secretome effectively tricks S. aureus into a premature exodus phase, where nuclease-mediated matrix degradation prevents the establishment of a stable biofilm architecture. These findings underscore the highly species-specific nature of fungal-bacterial interactions and identify a specific metabolic vulnerability in S. aureus that may be exploited to develop novel anti-biofilm strategies against polymicrobial communities.",

In this review, we discuss plant-derived natural products with potent anti-Candida activity, specifically terpenoids, alkaloids, flavonoids, phenolics, and their nanoformulations. Many compounds, including berberine, artemisinin, thymol, eugenol, carvacrol, quercetin, catechins, lawsone, and caffeic acid, have shown the ability to modulate the fundamental mechanisms of fungal growth, which include disrupting membranes, inhibiting ergosterol biosynthesis, modulating efflux pumps, inducing oxidative stress, and biofilm inhibition. Some phytochemicals also demonstrate synergism with azoles, polyenes, and echinocandins, which can support dose reduction and restoration of resistance. Ultimately, while there is supportive preclinical evidence for anti-Candida action via the aforementioned compounds, clinical translation has been limited due to issues concerning standardization of use, pharmacokinetic variability, and toxicity issues. Some recent advances in nano-delivery systems, structural bioactivity modifications, and molecular docking studies provide a path forward when considering ways to maximize antifungal properties and improve bioavailability. This review highlights current advancements, therapeutic opportunities, and critical research gaps to accelerate the integration of phytochemicals into antifungal stewardship and device-associated infection control strategies.",

Specifically, it seeks to identify major gaps and challenges in Candidozyma auris (C. auris) classification, diagnostic methods, virulence traits, antifungal therapy, and infection prevention, thereby providing a consolidated evidence base to support improved clinical management, surveillance, and future research. Recent advances have enabled rapid, accurate identification of C. auris using updated MALDI-TOF MS databases and real-time PCR assays. Novel antifungal agents and combination therapies offer potential options against resistant and biofilm-forming C. auris, while recent studies of aggregation, biofilm formation and adhesion, and phenotypic switching have provided new insights into its virulence and persistence in healthcare settings. C. auris exhibits many virulence traits that influence the severity of its infections. Identifying C. auris using conventional microbiological and culture-based methods can be challenging, often leading to delayed diagnoses and inappropriate treatment\u00a0of infections. Its resistance to commonly used antifungal drugs, including azoles, polyenes and echinocandins, further complicates infection control and treatment strategies.

Pronounced drug resistance makes treatment failure common, and so does antifungal tolerance, a phenomenon enabling pathogen survival at supra-MIC concentrations without resistance mutations. Here, we uncover a mechanism of antifungal tolerance in C. auris engaging the mitochondrial cytochrome bc1 complex. Deletion of RIP1, a conserved catalytic complex subunit, does not significantly alter the susceptibility to caspofungin or voriconazole. However, rip1\u0394 mutants exhibit a marked reduction in antifungal tolerance across a wide range of supra-MIC concentrations. Transcriptomics reveals the dysregulation of multiple drug resistance and tolerance-related genes in the rip1\u0394 mutant, demonstrating a role for Rip1 in controlling antifungal susceptibility. Targeting cytochrome bc1 function with the fungal-specific inhibitor Inz-5 enhances antifungal action of both voriconazole and caspofungin. Additionally, ablation of RIP1 causes fitness defects, suggesting that cytochrome bc1 is a potential antifungal target against C. auris infections.",

We retrospectively analyzed candidemia episodes diagnosed from 2018 to 2024 in a tertiary university hospital, evaluating incidence trends, species distribution, ward origin, antifungal susceptibility, and antifungal consumption in the context of the COVID-19 pandemic. Candidemia incidence remained high beyond the COVID-19 pandemic, particularly in intensive care unit. Candida parapsilosis species complex was the predominant pathogen, accounting for 41.4% in the post-COVID era, and exhibited persistently high fluconazole resistance rates of up to 64.3% together with increasing resistance to voriconazole. Increased azole resistance was associated with isolation from intensive care units. Candidozyma auris (Candida auris), first identified in 2022, rapidly became endemic, accounting for 29.5% of isolates in the post-COVID era and exhibiting uniform resistance to fluconazole. Candida albicans (18.5%) ranked as the third most frequently isolated species. Amphotericin B and echinocandins retained excellent in vitro activity, whereas the clinical utility of fluconazole was markedly reduced due to the high prevalence of resistant C. parapsilosis and C. auris.

Its ability to persist in hospital environments, colonize patients asymptomatically, and exhibit multi-drug resistance to antifungal drugs poses a major challenge to infection prevention and control (IPC). This work is a synthesis of published, hospital-based evidence on nosocomial C. auris infections in Saudi Arabia and Egypt, with implications for antifungal stewardship, infection prevention, and control. Saudi Arabia and Egypt were selected because of their contrasting surveillance, healthcare capacities, and reporting intensities, which allow for comparative regional interpretation. This narrative review was conducted using PubMed and Google Scholar for English-language articles from 2020 to 2025, with key terms including \"Candida auris,\" \"C. auris,\" together with related concepts such as epidemiology, transmission, IPC, Saudi Arabia, Egypt, and drug resistance, with an emphasis on hospital-based studies. Available evidence indicates a marked increase in reported cases and outbreaks in Saudi Arabia, with risk factors of ICU exposure, invasive medical device use, and antibiotic use, whereas data from Egypt though limited increasingly suggest misdiagnosis and emerging local circulation in tertiary care settings. Both countries exhibit high fluconazole resistance and variable susceptibility to amphotericin B, with echinocandins as the preferred first-line therapy. These findings highlight the urgent need for enhanced surveillance, improved diagnostic capacity, and sustained, consistent IPC strategies in healthcare settings across the regions to limit further spread of C. auris.",

Once regarded as mere curiosities of mycology, mycoviruses are now recognized as key players in tripartite mycovirus-fungus-plant interactions that reshape disease outcomes, endophytic lifestyles, and ecosystem resilience. Recent discoveries of cross-kingdom infection, core virome-mediated thermal tolerance, and reactive oxygen species (ROS) signaling hubs have substantially expanded our understanding of mycovirus biology.

Although bacterial pathogens, especially Staphylococcus aureus, are most commonly considered as causative agents, the contribution of opportunistic yeasts to chronic, non-healing footpad lesions remains poorly characterized. Keratinophilic yeasts may sustain the disease process by degrading keratin in superficial tissues, impairing wound healing and, owing to their thermotolerance and minimal nutritional requirements, persisting in the environment of the bird's enclosure. In this study, three captive steppe eagles (Aquila nipalensis) from a single aviary in Kazakhstan, all presenting with chronic pododermatitis unresponsive to antibacterial treatment, were investigated by integrated mycological, biochemical and molecular approaches. The yeast isolates were recovered from the deep footpad lesions and identified to species level by sequencing of the ITS1-5.8S-ITS2 rDNA region. All these isolates were assigned to Candida metapsilosis, and phylogenetic analysis confirmed their close clustering with reference C. metapsilosis sequences. Phenotypic characterization showed that all isolates were thermotolerant (growth at 8-37 \u00b0C), expressed strong urease and keratinolytic activity (the latter confirmed in vitro by the hair perforation test), high saccharolytic activity and selective, weak proteolytic activity. Disk diffusion screening showed susceptibility to azoles (ketoconazole, clotrimazole, fluconazole) and reduced susceptibility to polyenes (nystatin, amphotericin B). To our knowledge, this is the first report of C. metapsilosis isolated from chronic pododermatitis lesions in captive steppe eagles. Combined with the documented in vitro virulence-associated traits and the resolution of the lesions following targeted antifungal therapy, our findings support a contributory etiological role of C. metapsilosis as an opportunistic pathogen in raptor pododermatitis in immunocompromised birds maintained under suboptimal husbandry. Mycological work-up, including molecular identification, is therefore warranted in cases of chronic, non-resolving pododermatitis in captive birds of prey.",

In immunocompromised hosts, however, it can switch to a pathogenic state and cause infections. The molecular mechanisms underlying this commensal-pathogenic transition have not been fully elucidated. Here, we demonstrate that the mitochondrial protein Mcu1, which is required for utilization of multiple carbon sources, plays a crucial role in N-acetylglucosamine (GlcNAc)-induced phenotypic switching and gut commensalism in C. albicans. Disruption of Mcu1 or key TCA cycle enzymes impaired GlcNAc utilization, blocked white-to-opaque switching under in vitro culture conditions, and reduced gut colonization in a murine model. Mechanistically, Mcu1 sustains respiratory metabolism by regulating key oxidoreductases, while also promoting gut commensalism by enabling in vivo activation of the master regulator Wor1. Collectively, our findings reveal that Mcu1 and key TCA cycle enzymes play an essential role in phenotypic switching and cooperatively regulate the commensal-pathogenic transition in C. albicans.",

C.\u00a0auris has the ability to spread very fast inside the hospital environment and cause outbreaks worldwide. It has a very high affinity toward skin colonization, especially in the areas like axilla and groin. Based on whole genome sequencing it is classified into five clades.

This can only be resolved by establishing diagnosis at molecular levels. Whole genome sequencing and polymerase chain reaction are some of the important molecular diagnostic methods for detection of C. auris. MALDI-TOF-MS is a culture based highly efficient method that is widely being used for C. auris identification. Treatment of C. auris infection depends on effective antifungal therapy, as multidrug resistance is quite common, the drug regime is decided after antifungal sensitivity testing. It is commonly treated with echinocandins and polyenes. Apart from the antifungal therapy it is also important to monitor the fungemia by performing blood cultures.

To this end, the minimum inhibitory concentration (MIC) of DUL alone and in combination with conventional antifungals was determined in order to evaluate the type of interaction between them, as well as the minimum fungicidal concentration (MFC). The activity of DUL against mature and developing biofilms was evaluated, in addition to the possible antifungal mechanism of action. DUL showed MICs of 16 to 128\u00a0\u00b5g/mL with a fungicidal action profile, and when combined there was synergistic interaction with amphotericin B (AMB). In biofilms, DUL exhibited antibiofilm activity and enhanced AMB activity against developing, but not mature, biofilms. Mechanism of action analysis showed that DUL promoted oxidative stress, evidenced by increased reactive oxygen species (ROS) production, reduced GSH levels, mitochondrial depolarization, and phosphatidylserine externalization, suggesting the activation of the apoptotic pathway as a possible mechanism of cell death. The pro-oxidant effects of DUL were evident in C. albicans strains deficient in antioxidant defenses (cap1\u0394 and gpx3\u0394) compared to the wild-type strain. DUL exhibited antibiofilm activity and enhanced AMB activity against developing, but not mature, biofilms.",

Here, we investigated whether laboratory exposure of a clade III clinical C. auris isolate to TCZ could induce cross-resistance to clinical antifungals. Among 17 agrochemicals tested, only TCZ exhibited intrinsic antifungal activity. Brief (48 h) exposure to sub-MIC TCZ (1 \u03bcg/mL) selected variants (6.9% frequency) with cross-resistance to TCZ and fluconazole, but full susceptibility to caspofungin. Exposure to supra-MIC TCZ (8-32 \u03bcg/mL) produced three phenotypic classes: Class 2 (TCZ-R, fluconazole-R) and Class 3 (TCZ-R, fluconazole-R, plus tolerance to caspofungin and micafungin). The frequency of Class 3 increased dose-dependently from 23% to 50% as TCZ concentration rose. RNA-Seq revealed that both classes overexpressed MDR1, TAC1b, UPC2 and FKS1, but Class 2 showed broad ergosterol pathway upregulation, whereas Class 3 exhibited restricted ergosterol activation but downregulation of the sole chitinase gene CHT1 (5.17-fold), a known mechanism of echinocandin tolerance. Unlike the CRS-MIS phenomenon in Candida glabrata, our Class 3 adaptors displayed equal tolerance to both caspofungin and micafungin. Collectively, these findings demonstrate that, in a clade III clinical isolate of C. auris under the tested laboratory conditions, laboratory exposure to an agricultural triazole can rapidly select for clinically relevant azole cross-resistance and echinocandin tolerance in C. auris, suggesting that environmental fungicide use may inadvertently compromise the efficacy of last-line antifungals.",

        "42549922": "ID: 42549922\nTitle: Baicalein suppresses adhesion and biofilm formation in Candida auris.\nAbstract: Candida auris, an emerging multidrug-resistant fungal pathogen, poses a severe global public health threat owing to its high nosocomial transmissibility, considerable mortality, and widespread antifungal resistance. Baicalein (BE), a major bioactive constituent of Scutellaria baicalensis Georgi, exhibits notable antifungal potential, yet its specific molecular mechanisms against C. auris remain poorly elucidated. In this study, we determined the antifungal activity of BE against multiple C. auris isolates, assessed its effects on fungal growth, virulence attributes, adhesion, and biofilm development, validated its in vivo protective efficacy in a Galleria mellonella infection model, and explored the underlying mechanisms via transcriptomic sequencing. BE exerted potent and consistent antifungal activity against all tested strains, with a minimum inhibitory concentration of 1 \u03bcg/mL, minimum fungicidal concentrations of 4-8 \u03bcg/mL, and a sessile minimum inhibitory concentration of 32 \u03bcg/mL. It time- and concentration-dependently suppressed fungal growth, virulence factor expression, adhesion to biological and non-biological surfaces, and biofilm formation, while conferring significant in vivo protection against C. auris infection. Transcriptomic analysis identified 11 adhesion- and biofilm-associated target genes, among which SCF1 and ALS1 served as pivotal regulators. Collectively, BE exerts robust anti-C. auris effects by modulating key target gene expression to interfere with multiple virulence-related processes, providing experimental support for its development as a novel antifungal agent for C. auris infection treatment.IMPORTANCEThe emerging multidrug-resistant fungal pathogen Candida auris has become a critical global public health concern. Its pronounced nosocomial transmissibility, high infection-associated mortality, and extensive cross-resistance to mainstream antifungal agents have created substantial unmet needs in clinical treatment and nosocomial infection control. In this study, we systematically validated the in vitro and in vivo antifungal activity of baicalein against C. auris and elucidated the molecular mechanism underlying its modulation of virulence-related genes. Our findings provide a pivotal experimental basis for the development of novel antifungal therapeutics targeting C. auris infections.",

Owing to this resilience, pathogenic fungi that form chlamydospores are particularly difficult to control. Therefore, understanding the mechanisms of chlamydospore formation is critically important. Here, we show that the hyphae of the filamentous fungus Trichoderma guizhouense can differentiate into typical terminal and intercalary chlamydospores characterized by double-layered spherical or ellipsoidal cell walls with accumulated lipid bodies and nuclei. We found that during chlamydospore formation, ribosome biogenesis was gradually downregulated, indicating the entry of cells into dormancy. Comparative transcriptomic analyses across developmental stages and media identified the Gti1/Pac2 family protein CFG1 as an essential regulator, as the \u0394cfg1 strain failed to form chlamydospores under all inducing conditions. Lipidomic analysis showed its involvement in lipid metabolism, and mutants lacking lipid metabolism genes pdat or dgat produced fewer chlamydospores. Our work reveals the molecular mechanism of chlamydospore formation in T. guizhouense.IMPORTANCEIn fungal biology, the morphological transition from vegetative hyphae to thick-walled, lipid-rich chlamydospores represents a fundamental developmental switch into dormancy, crucial for survival under environmental stress. Understanding the regulatory mechanisms behind this process is essential for deciphering the basic principles of fungal cell differentiation and adaptation. This study employs multi-omics approaches to systematically characterize chlamydospore formation and identifies the Gti1/Pac2 family protein CFG1 as a master regulator. Functional analysis reveals that CFG1 governs this transition by directly influencing lipid metabolism-a key pathway for spore maturation and structural integrity. These findings uncover a previously unknown molecular switch in fungal development and provide new insights into how filamentous fungi coordinate metabolic reprogramming with cellular differentiation to ensure long-term survival.",

This process governs diverse cellular programs, from stress response and morphogenesis to disease pathology. Over the past two decades, the regulatory impact of biomolecular condensates in fungal biology has become increasingly recognized. In this review, we examine the fundamental molecular mechanisms driving LLPS, evaluate the current evidence for LLPS in macromolecular organization and cellular regulation in fungi, and outline the tools employed to study this phenomenon. Lastly, we highlight the challenges of bridging the gap between the in vitro behavior of biomolecular condensates and their complex regulatory functions in vivo within fungal biology.",
        "42554648": "ID: 42554648\nTitle: NT-A9, a new triazole, exhibits potent antifungal activity against Candida and Cryptococcus species through potent ergosterol biosynthesis inhibition.\nAbstract: Invasive fungal infections (IFIs) remain a major global health threat due to limited therapeutic options and rising azole resistance. NT-a9 is a novel triazole antifungal with potent activity against Candida and Cryptococcus species via strong inhibition of ergosterol biosynthesis. In vitro, NT-a9 exhibited potent and sustained antifungal activity against clinical isolates, with superior potency compared to fluconazole (FLC). It also displayed a prolonged post-antifungal effect (PAFE) against most Candida species, a property rarely seen in conventional azoles. Resistance profiling demonstrated that NT-a9 possesses a high genetic barrier, fully suppressing resistant mutant emergence in Cryptococcus species and maintaining stable susceptibility in Candida albicans during 28 days of continuous exposure. NT-a9 retained potent activity against FLC-resistant Cryptococcus neoformans and multidrug-resistant Candida auris, with minimal influence from drug efflux mechanisms. In murine invasive candidiasis, a single low dose of NT-a9 achieved 100% survival and markedly reduced renal fungal burden, significantly outperforming FLC. NT-a9 also substantially improved survival in mice infected with FLC-resistant C. auris. Mechanistically, NT-a9 binds Erg11 with much higher affinity than FLC by forming key hydrogen bonds with Gly307 and His377, leading to irreversible ergosterol depletion, toxic sterol accumulation, and severe fungal membrane damage. Transcriptomic analysis further confirmed that NT-a9 extensively disrupts sterol biosynthesis and triggers compensatory gene expression that reinforces its antifungal action. As a novel triazole integrating long-lasting efficacy, a high resistance barrier, and potent activity against pan-azole-resistant pathogens, NT-a9 represents a promising clinical candidate for treating IFIs.",
        "42554883": "ID: 42554883\nTitle: Antibiofilm and anti-hyphal activity of a valencene-enriched fraction against Candida albicans.\nAbstract: In recent years, the emergence of azole-resistant Candida albicans strains has contributed to increased treatment failure with conventional antifungal therapies. Given the critical role of hyphal formation and biofilm development in C. albicans pathogenicity, this virulence traits represent important but challenging therapeutic targets. In this context, natural products have gained attention as potential sources of novel antivirulence agents. This study investigated the effects of a valencene-enriched fraction (VEF) derived from citrus fruits on the virulence characteristics of C. albicans. VEF significantly inhibited biofilm formation and reduced metabolic activity in vitro. Furthermore, it effectively suppressed the yeast-to-hyphal transition, preventing filamentation under both solid and liquid growth conditions. In an in vivo Caenorhabditis elegans infection model, VEF treatment significantly increased host survival compared to untreated infected controls. Importantly, VEF exhibited no observable toxicity toward nematodes, even at higher concentrations. At the molecular level, RT-PCR analysis revealed that VEF treatment significantly downregulated key hypha- and biofilm-associated genes, including hwp1, als3, egf1, and cph1 suggesting interference with the major regulatory pathways governing morphogenesis and virulence. Overall, these findings indicate that VEF possesses promising antibiofilm and anti-hyphal activities and supports its preliminary antivirulence potential. Rather than suggesting direct therapeutic applications, this study highlights VEF as a candidate for further antivirulence and mechanistic investigations. In particular, the results support valencene as a potential antivirulence scaffold for future research aimed at addressing antifungal resistance and pathogenicity in C. albicans."
