In this study, we evaluated the effect of BRSV infection on the adhesion of T. pyogenes to BRSV-infected cells. BRSV infection significantly enhanced the adhesion of T. pyogenes to cells in a multiplicity of infection- and time-dependent manner. The BRSV-mediated change in the adhesion of T. pyogenes was widely observed in various cell types and bacterial strains. The results from the gentamicin protection assay showed that BRSV infection did not affect the intracellular invasion ability of T. pyogenes. Furthermore, adhesion assays conducted using BRSV G protein-expressing cells and anti-BRSV G antibodies revealed that the increased adhesion of T. pyogenes to cells was mediated by the G protein of BRSV. In addition, immunofluorescence assay revealed the colocalization of BRSV G protein and T. pyogenes. Thus, BRSV infection can potentially lead to bovine respiratory disease complex by promoting the adhesion of T. pyogenes to the infected cells.","PeriodicalId":49959,"journal":{"name":"Journal of Veterinary Medical Science","volume":" ","pages":"1068-1075"},"PeriodicalIF":1.1,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11442402/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141903378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

HPAI poses significant challenges due to its high mortality rate and public health concerns, with outbreaks spreading globally since the emergence of the H5N1 virus in 2003. In Japan, HPAI outbreaks have been particularly prevalent during autumn and winter seasons, with the 2022-2023 winter experiencing the most severe outbreak to date. However, limited research has directly examined the association between HPAI outbreaks and weather conditions in Japan. Here we show that specific weather conditions are associated with an increased risk of HPAI outbreaks on poultry farms in Japan. By analyzing databases of HPAI cases and meteorological data from 2020-2023, we found that higher average air temperatures two to three weeks prior, lower average wind speeds four weeks prior, and longer sunlight hours two and four weeks prior to outbreaks were significantly associated with increased risk of HPAI outbreaks in Japan. These results suggest that weather may influence environmental survival and transmission of the virus, as well as patterns of wild bird movement that could seed new outbreaks. These findings enhance our understanding of the factors influencing HPAI transmission dynamics and highlight the importance of integrating weather forecasts into disease surveillance and prevention strategies.","PeriodicalId":49959,"journal":{"name":"Journal of Veterinary Medical Science","volume":" ","pages":"1045-1051"},"PeriodicalIF":1.1,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11442392/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142001157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is necessary to identify the precise advantages of 3D-printed models from all perspectives; not only the improvement in students' knowledge of anatomy but also the students' assessment of such models. Here, students of veterinary medicine and animal science evaluated the reproducibility and effectiveness of 3D-printed models as a learning tool by completing our questionnaires, with a focus on their understanding of the skull-morphological differences among dog breeds. With the COVID-19 pandemic having obliged veterinary universities to provide courses online, we also investigated how the pandemic affected the students' evaluation of the 3D-printed models. The questionnaire results revealed that the animal science students were satisfied with the reproducibility of the 3D-printed models, but the veterinary students were not (they preferred to use real specimens). The skull differences were well understood by both types of students, indicating that 3D-printed models are effective for learning about rare skeletal specimens. The veterinary students who experienced the COVID-19 pandemic tended to choose real specimens more often than those who did not have this experience. Our results suggest that the use of 3D-printed models as an introduction and the use of real specimens in anatomy laboratory courses can be adequate for veterinary students. Together our findings suggest ways to improve the educational performance of 3D-printed models for veterinary students who need to understand the anatomy of many species.","PeriodicalId":49959,"journal":{"name":"Journal of Veterinary Medical Science","volume":" ","pages":"1081-1088"},"PeriodicalIF":1.1,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11442399/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142094105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, because rodents are the primary reservoir hosts for T. gondii, if this characteristic manifests in the wild, type I strains would be extinct. Therefore, we hypothesized that populations of wild rodents capable of harboring type I T. gondii asymptomatically exist globally and are not limited to a few localized areas, as previously thought. The strength of mouse resistance to T. gondii is known to depend on the affinity of the mouse-expressed immunity-related GTPases B2 (IRGB2) protein for the T. gondii-expressed rphoptry protein 5B (ROP5B) protein. Therefore, the Irgb2 gene sequences of 12 individuals mice captured at two animal farms in Gifu Prefecture, and on an island in Okinawa Prefecture, Japan were determined, and subjected to a molecular phylogenetic analysis together with those of various mouse strains worldwide. The Irgb2 gene of M. musculus individuals captured on one farm and one island showed diverse sequences. The sequences from two individual mice captured in an animal farm formed a single clade with a wild mouse derived CAST/EiJ strain, known for its exceptional resistance to type I T. gondii lethality. These results suggest that M. musuculus individuals resistant to the Type I T. gondii strain may be present in Japan, in addition to the previously known populations in South Asia, Thailand and India.","PeriodicalId":49959,"journal":{"name":"Journal of Veterinary Medical Science","volume":" ","pages":"1056-1062"},"PeriodicalIF":1.1,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11442403/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142001158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although FPV vaccination is routinely practiced in China, clinical diseases continue to occur. The investigation of genotypes and viral evolution can contribute to the prevention, diagnosis, and treatment of FPV. Therefore, this study aimed to provide an up-to-date understanding of the epidemiological, genotypic, and phylogenetic characteristics of FPV. In total, 152 rectal swabs were collected from diseased cats. All swab samples were tested for FPV using molecular methods. Amplification of the complete viral protein 2 (VP2) gene was performed for further analysis and to infer the genotypic and evolutionary characteristics of FPV. Of the 152 samples, FPV DNA was detected in 17 (17/152, 11.18%). Cats with FPV showed variable clinical signs such as dehydration, anorexia, fever, vomiting, and blood-stained diarrhea. Furthermore, VP2 sequences were identified in 17 PCR-positive cats, confirming the presence of FPV. Phylogenetic and nucleotide pairwise identity analyses revealed high genetic similarity among FPV sequences (99.6-100%) and clustered them into the FPV-G1 group. Amino acid analysis indicated a novel mutation (Ala91Ser) in all VP2 gene sequences amplified in this study. Our study provides baseline epidemiological data for the better prevention of FPV with respect to vaccination strategies. Genotypic and phylogenetic analyses confirm that FPV-G1 was the predominant FPV group in infected cats in Kunshan. Therefore, a rigorous countrywide investigation of the genotypic and evolutionary characteristics of FPV is warranted.","PeriodicalId":49959,"journal":{"name":"Journal of Veterinary Medical Science","volume":" ","pages":"1032-1039"},"PeriodicalIF":1.1,"publicationDate":"2024-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11422690/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141621599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
