MCT has not been reported previously in a chiropteran species, to our knowledge.

We investigated the prevalence of PCV2 and PCV3 in eastern Serbia by analyzing 166 wild boar samples with a real-time PCR assay. The cumulative prevalence of PCV2 and PCV3 was 72.7%, with true prevalence estimates of 59.2% for PCV2, 49.0% for PCV3, and 31.0% for coinfection. We found higher prevalence of PCV2 and PCV3 in the Južnobanatski district compared to previous reports, likely due to differences in detection methods and the inclusion of liver samples. Backyard farms, with free-ranging animals and natural breeding, dominate eastern Serbia, facilitating frequent interactions between wild and domestic pigs. The overlap between backyard and commercial farming practices, along with high wild boar densities and cross-border movements, likely facilitate viral transmission. These conditions, coupled with inadequate biosecurity measures, such as swill feeding and improper disposal of offal, amplify the risk for viral dissemination, with significant implications for spillover into domestic pig populations. Enhanced biosecurity and monitoring strategies are crucial to mitigate the risk of pathogen transmission between wild and domestic pig populations.","PeriodicalId":17579,"journal":{"name":"Journal of Veterinary Diagnostic Investigation","volume":" ","pages":"10406387251325534"},"PeriodicalIF":1.2,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11904918/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143605398","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 association between yersiniosis and reproductive complications is known, systematic studies and case series on abortion in sheep and goats are scarce. Here we describe epidemiologic and pathologic findings in 34 cases of Yersinia pseudotuberculosis- and Y. enterocolitica-associated abortions in sheep and goats, contributing to the understanding of these zoonotic diseases in California. We conducted a 22-y retrospective study to examine microbiologic and pathologic findings in abortion submissions, as well as the geographic and seasonal distribution of the analyzed cases. Yersiniosis-induced abortion was diagnosed in 22 goats and 12 sheep, with all abortions occurring in the last third of gestation. Samples from lung, liver, placenta, and abomasal contents were submitted for aerobic culture; the highest recovery of Yersinia spp. was from abomasal contents. Microscopically, there was severe necrotizing and suppurative inflammation in the lung, liver, spleen, kidney, and, when present, the placenta, with intralesional bacterial colonies. All cases were received from northern and central California in the winter and spring. Our study provides epidemiologic and pathologic features of Yersinia spp.-induced abortions in small ruminants and provides critical data to pave the way for future research, surveillance, and preventive strategies.","PeriodicalId":17579,"journal":{"name":"Journal of Veterinary Diagnostic Investigation","volume":" ","pages":"10406387251324883"},"PeriodicalIF":1.2,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11904924/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143605373","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To date, the methods used for the identification of species within the genus Serratia, including PCR assays, have poor discriminatory power and may require further molecular typing or genomic sequence analysis to determine clinical relevance. We developed a duplex TaqMan probe-based quantitative real-time PCR (qPCR) assay targeting the chiP gene, which is involved in chitin degradation and transport, and the ureD gene, which is involved in urease production. This allowed us to simultaneously identify all members of the S. marcescens complex (chiP positive) and differentiate those most likely to act as insect pathogens (chiP and ureD positive). We applied our assay to identify potentially entomopathogenic members of the S. marcescens complex in the context of a conservation program for the critically endangered insect Dryococelus australis and found it to be a useful aid for rapid and accurate detection of infection with S. marcescens complex strains in insects and determination of their clinical relevance. By targeting 2 genes likely to be virulence factors, this assay may also be of use for research investigating the pathogenesis of entomopathogenic Serratia spp.","PeriodicalId":17579,"journal":{"name":"Journal of Veterinary Diagnostic Investigation","volume":" ","pages":"234-243"},"PeriodicalIF":1.2,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11773504/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143047148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
