CLAIM EVALUATED AND ANSWER TO USER


"The assertion that 'bison attack' is a primary cause of mortality in livestock or a significant, well-documented clinical threat in the context of recent veterinary forensic literature."

ABSTRACT & REWRITTEN CLAIM


Scientific synthesis of the role of bison as both victims and vectors of disease, and an evaluation of the prevalence of "bison attack" as a mortality category in veterinary forensic case archives.

INTRODUCTION & JUSTIFICATION


The provided veterinary forensic literature categorizes mortality in animals into specific macro-categories. While "attack" is identified as the most frequent cause of mortality in livestock within the archive of the Istituti Zooprofilattici Sperimentali (2013-2023), the classification of such attacks does not specifically isolate bison as the primary aggressors. Instead, bison themselves are frequently documented as the victims of environmental and biological stressors, including urolithiasis, digital dermatitis, BTV-3 (Bluetongue virus), and Influenza A. The literature demonstrates that "attack" is a significant forensic category, but it is context-dependent and does not explicitly frame bison as the predominant perpetrators of livestock mortality.

DISCUSSION: NOVEL & OVERLOOKED


* Bison demonstrate high susceptibility to the 2022-2025 reassortant Oropouche virus (OROV), showing the greatest replication success among eight tested mammalian cell lines.
Digital dermatitis, associated with *Treponema spp., has reached a 94.4% prevalence in Swiss European bison populations.
* "Attack" is the most frequent cause of mortality in livestock within the retrospective study of Italian IIZZSS archives, yet this classification aggregates various sources of trauma.
* European bison (Bison bonasus) and American bison (Bison bison) were identified as species experiencing high morbidity during the 2024 Bluetongue virus Serotype 3 outbreak in Belgian zoos.
* A 4-year-old captive European bison was the first documented case of molecular evidence for H1N1pdm influenza infection, highlighting interspecies spillover risks.
* While forest disturbances enhance habitat suitability for large herbivores, such as bison, over the long term, they also facilitate interactions that may increase the risk of disease transmission or wildlife-livestock conflict.

ID: 41863702 Title: First report of serological and molecular detection of influenza A (H1N1) in European bison (Bison bonasus). Abstract: Influenza A virus is a zoonotic pathogen capable of infecting a wide range of hosts, yet data on infections in wild ruminants are limited. The European bison (Bison bonasus), Europe’s largest terrestrial mammal, had not previously been identified as a host for Influenza A virus. This study aimed to provide the first molecular and serological evidence of H1N1 pandemic influenza A virus (A/H1N1pdm) infection in European bison, contributing to the understanding of Influenza A virus ecology at the wildlife–livestock interface. We retrospectively analysed 335 serum samples collected from European bison between 2017 and 2023 using a commercial ELISA detecting antibodies against all Influenza A virus subtypes. Tissue samples (heart and liver) from ELISA-positive animal were further tested by RT-qPCR targeting hemagglutinin (HA) and neuraminidase (NA) genes of A/H1N1pdm, A/H3N2, and A/H5N1. PCR-positive products were sequenced for confirmation. Seroprevalence of Influenza A virus was 0.3% (1/335; 95% CI: 0.02–1.71). Influenza A virus RNA (A/H1N1pdm) was detected in the heart and liver tissue of a 4-year-old captive male from Borecka Forest, culled in 2018. The animal exhibited pulmonary congestion, emphysema, and posthitis at necropsy. This study provides the first molecular and serological confirmation of H1N1pdm infection in European bison. The findings highlight the potential susceptibility of this species to Influenza A virus and raise questions about possible transmission routes, including spillover from domestic animals or humans.

ID: 42007470 Title: Bluetongue Virus Serotype 3 Follow-Up of the 2024 Outbreak in Two Belgian Zoos. Abstract: In summer 2024, Western Europe experienced extensive outbreaks of bluetongue virus Serotype 3 (BTV-3), a Culicoides-borne orbivirus. Clinical disease was first detected in August 2024 in one of two Belgian zoos, predominantly affecting European bison (Bison bonasus) and American bison (Bison bison). These species showed high morbidity, two fatalities, and severe multisystemic lesions at necropsy. This outbreak coincided with reemergence of BTV-8 and increasing reports of emerging BTV-12 and epizootic hemorrhagic disease virus (EHDV) circulation in Europe. Following the outbreak, samples from 116 animals representing 33 species were analyzed across two Belgian zoos (urban and rural), spanning a 20-year period (2005-2025). Species belonged to Artiodactyla, Perissodactyla, Proboscidea, Rodentia, Diprodontia, and Carnivora. Archived sera predating 2024 (retrospective), samples collected during the 2024 outbreak (outbreak), and follow-up samples obtained through June 2025 (follow-up) were tested at the Belgian National Reference Laboratory (NRL). Antibodies were screened using a pan-BTV ELISA, and ELISA-positive samples were further analyzed by virus neutralization tests (VNTs) to differentiate BTV-3 and BTV-8. Viral RNA detection was performed using RT-qPCR assays targeting pan-BTV, BTV-3, BTV-12, and EHDV. Serological reactivity was confined to Artiodactyla and Perissodactyla. In total, 46 ruminants (67% of tested ruminants) and one greater one-horned (GOH) rhinoceros (Rhinoceros unicornis) were ELISA positive. VNT confirmed BTV-3 infection in 62% and BTV-8 in 9% of seropositive ruminants. Viral RNA was detected in whole blood from 28 individuals, representing 42% of the tested ruminants. Marked epidemiological differences were observed between zoos, with limited detection in the urban collection and widespread infection in the rural collection, likely reflecting differences in vector exposure. No evidence of BTV-12 or EHDV was detected. This study provides comprehensive documentation of BTV-3 in zoo-housed species, integrating clinical, pathological, and longitudinal surveillance data. It underscores pronounced interspecies variability in susceptibility and immune response, providing critical insights for outbreak preparedness.

ID: 42075694 Title: Susceptibility of Livestock, Wildlife, and Domestic Host Species Cells to the 2022-2025 Reassortant Oropouche Virus. Abstract: Oropouche virus (OROV) is an emerging zoonotic arthropod-borne virus of public health importance. The host range of OROV is largely unknown, but antibody evidence suggests that wildlife and livestock species could be susceptible hosts. To identify potential North American mammalian reservoir hosts, OROV replication curves were generated using eight cell lines derived from livestock, wildlife, and domestic animal species (cow, sheep, bison, white-tailed deer, elk, pig, horse, and dog). The virus replicated in all cell lines by 48 h post infection, except for the horse cells. OROV replication success was greatest in the bison cells followed by pig and dog cells. Moderate replication was achieved in the deer, elk, sheep, and cow cells. These results indicate that numerous animal species may be susceptible hosts for OROV, including important agricultural and wildlife species, but pathogenesis studies are required to confirm this finding. Identifying the reservoir hosts for OROV will allow livestock producers, veterinarians, and public health officials to prepare appropriate vector and disease control measures should the virus initiate an outbreak in the United States.

ID: 42405726 Title: PREVALENCE OF DIGITAL DERMATITIS IN EUROPEAN BISON (BISON BONASUS) IN SWITZERLAND AND REFERENCE TO OTHER EUROPEAN COUNTRIES. Abstract: In 2018, digital dermatitis (DD) associated with Treponema spp. was detected in a herd of European bison (EB, Bison bonasus) in Switzerland. This follow-up study was carried out in 2021-2022 to evaluate the DD prevalence in the Swiss EB population (n = 49) by taking photographs and biopsies of the interdigital cleft of 10 anesthetized and eight deceased animals from five out of the six Swiss EB herds. Further samples of captive animals were available from Germany (n = 4), France (n = 1), and Poland (n = 1), and of free-living individuals from Germany (n = 4) and Poland (n = 11). Except for the Polish specimens, of which only one front foot per animal was available, all four feet were examined. Overall, 120 feet from 39 animals were available. Biopsies were taken according to a standardized protocol and investigated by histopathology, Treponema spp. fluorescence in situ hybridization (FISH) and full-length 16S rRNA gene sequencing. In addition, a transmission electron microscopy (TEM) examination was performed on tissues of randomly selected animals (n = 7). For the Swiss population, a DD prevalence of 94.4% (72.7-99.9%) was determined. Overall, 89/120 (74.2%) feet presented with macroscopic lesions. Histopathologically, a perivascular and lymphoplasmacytic dermatitis was present in 86/119 (72.3%) of the feet. In TEM, helically coiled bacteria were identified within the tissue of four animals, whose morphology confirmed them to belong to the order Spirochaetales. FISH was positive in 60/116 (51.7%) samples. 16S rRNA gene sequencing revealed the presence of three Treponema phylotypes (PT1, PT12, and PT3), which were clearly distinct from previously reported Treponema spp. in cattle and other ruminant species. This study shows that DD associated with Treponema spp. is widespread in Swiss EB herds and in other European individuals. So far, the disease does not seem to have a significant clinical relevance for EB, as clinical signs, such as lameness were not evident.

ID: 42440463 Title: Retrospective classification of veterinary forensic cases from the archives of the Italian Istituti Zooprofilattici Sperimentali (2013-2023). Abstract: Definitive guidelines for the classification of cases in Veterinary Forensic Medicine (VFM) are currently unavailable. An attempt to classify lesions observed in forensic necropsies was proposed in 2022 following the codes of the ICD-11. The archives of the Istituti Zooprofilattici Sperimentali (IIZZSS) are structured to identify forensic pathology cases using pre-coded information only on wild animals' mortality and suspected animal poisonings at the time of acceptance. In contrast, other forensic documentation sources, including non-pre-coded necropsy diagnoses, require interpretation based on laboratory test results and accompanying expert opinions. This study proposes the classification of previously unclassified VFM cases through a three-step approach: (1) data analysis, (2) review and classification of expert opinions by assigning labels corresponding to the main forensic topics, and (3) organization of diagnoses into categories and subcategories. Cases recorded in the database of the Istituto Zooprofilattico Sperimentale dell'Abruzzo e del Molise between 2013 and 2023 were retrospectively evaluated. A total of 1,221 non-coded cases with an expert opinion were identified. Among these, 405 cases (33.16%) were classified as potential Veterinary Forensic Cases and categorized into five macro-categories and 19 subcategories. The main cause of mortality differed according to animal type: injury was the most frequent cause in pets, attack in livestock, and unlawful killing in wildlife. This classification approach enabled the identification and organization of previously unclassified VFM cases within the institutional database. Poisoning cases and wild animal deaths caused by vehicular collisions were excluded as they were already pre-classified. Therefore, the reported percentages refer only to this subset of cases and do not reflect the overall mortality rates in the region.
