Pb is a known environmental toxin that can cause several issues in wildlife. Pb is still used in human society, and among Pb products, ammunition is reported to harm human and animal health. In Japan, few instances of Pb contamination in wild animals have been reported outside Hokkaido. Possible reasons for this include the absence of Pb contamination and insufficient investigation. This study aimed to understand the current state of Pb contamination in Japan and clarify the extent of Pb contamination related to ammunition. Blood lead concentrations (BLLs) were measured in wild birds and mammals from 25 municipalities, and an analysis was conducted based on ammunition-related factors. More than half of the avian and mammalian taxonomic groups were found to exhibit Pb contamination from environmental sources. Overall, this study suggests that Pb contamination is also present in wild birds and mammals living outside Hokkaido, Japan, and highlights the risks of mass mortality during infectious disease outbreaks as well as the potential health hazards of Pb exposure upon their consumption by humans. The results of this study highlight the importance of monitoring Pb contamination, particularly in hunting areas of Japan. Further, it indicates the need to reconsider the use of Pb-based ammunition for protecting the health and welfare of both humans and wildlife.","PeriodicalId":49959,"journal":{"name":"Journal of Veterinary Medical Science","volume":" ","pages":"911-918"},"PeriodicalIF":1.1,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12344314/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144327575","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}

The nasopharyngeal and palatine tonsils are mucosal-associated lymphoid tissue components that are the initial barrier to respiratory pathogens. In the present study, we investigated 5 pneumonic Japanese black and 3 control calves (2 Japanese black and 1 Holstein). The localization of M. bovis in the nasopharyngeal, palatine tonsils, and lungs was examined using nested and multiplex polymerase chain reaction (PCR), histopathology, and in situ hybridization (ISH) techniques. Nested PCR revealed that all examined tissues from all pneumonic calves were positive for M. bovis infection, but not the control. Histopathology revealed suppurative nasopharyngeal tonsillitis and palatine tonsillar cryptitis in all cases. Surprisingly, prominent histologic changes were observed in the palatine tonsils but not in the nasopharyngeal tonsils. Necrotizing suppurative bronchopneumonia was observed in 4 pneumonic calves. In ISH analysis, positive hybridization signals adherent to and/or within the surface epithelium of nasopharyngeal tonsils and crypt epithelium of nasopharyngeal and palatine tonsils were observed. Additionally, these signals were seen in the palatine tonsillar cryptic detritus. In the lungs, ISH signals were observed in necrotic areas, the bronchial epithelium, and pulmonary inflammatory exudate. These findings suggest that the nasopharyngeal and palatine tonsils are the primary sites of M. bovis infection. Also, M. bovis can colonize the detritus in the crypts of the palatine tonsils of the pneumonic animals.","PeriodicalId":49959,"journal":{"name":"Journal of Veterinary Medical Science","volume":" ","pages":"924-933"},"PeriodicalIF":1.1,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12344299/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144555565","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}

Cystatin C (CYS-C), a useful marker for evaluating renal function in humans with PH, has not been studied in dogs. This study aimed to compare seventeen dogs with PH to a control group, evaluating the relationship between PH and renal parameters such as symmetric dimethylarginine (SDMA), creatinine, and CYS-C. The mean tricuspid regurgitation maximal velocity (TRmax) and systolic pulmonary arterial pressure (SPAP) in dogs with PH was 4.24 m/sec and 74.48 mmHg, respectively. Dogs with PH exhibited significantly higher SDMA (15.47 μg/dL vs. 10.55 μg/dL) and CYS-C (1.36 mg/L vs. 0.88 mg/L) compared to controls. SDMA showed moderate positive correlations with SPAP (r=0.682) and TRmax (r=0.662), and a negative moderate correlation with mean arterial pressure (r=-0.590). CYS-C moderately correlated with SPAP (r=0.529), TRmax (r=0.485), heart rate (r=0.506), and body weight (r=0.691). Creatinine did not vary significantly between PH group (122.21 μmol/L) and controls (93.70 μmol/L), nor did it correlate with any parameters. Multivariate analysis revealed that CYS-C was significantly influenced by PH severity, while SDMA and creatinine were not. These findings suggest that renal dysfunction is prevalent in dogs with PH. CYS-C may be a more sensitive marker for detecting early renal changes linked to PH severity, while SDMA appears to be more specific to true renal dysfunction and creatinine was the least informative biomarker.","PeriodicalId":49959,"journal":{"name":"Journal of Veterinary Medical Science","volume":" ","pages":"868-875"},"PeriodicalIF":1.1,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12344298/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144303405","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 the prevalence of AA amyloidosis in cattle at slaughterhouses has been reported in several studies, how much bovine AA is distributed in retail stores remains unknown. In this study, to clarify the food hygienic risk of bovine AA, we collected beef livers from seven commercial retail stores in Japan to investigate the deposition rate and the transmissibility of bovine AA. Congo red staining and immunohistochemistry revealed bovine AA deposition in two of 185 commercial beef livers (1.08%). No differences were observed between the gross appearance of amyloid-laden and amyloid-free livers. Administration of bovine AA from commercial beef liver to mice, either intraperitoneally or into the spleen, did not promote the development of AA amyloidosis. This contrasts with previous studies demonstrating cross-species transmission of AA amyloidosis via intraperitoneal or even oral administration of bovine AA. Although the cause of this discrepancy is unknown, the low transmissibility may be related to the species-barrier. These results support that the actual food hygienic risk of AA amyloidosis associated with consuming commercial beef liver may not be significant.","PeriodicalId":49959,"journal":{"name":"Journal of Veterinary Medical Science","volume":" ","pages":"887-893"},"PeriodicalIF":1.1,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12344302/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144276472","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}
