We describe here a series of 42 cases of radial fractures observed in California racehorses. Autopsy findings from all racehorses submitted for postmortem examination between 2006 July 1 and 2022 June 30 that had a recorded radial fracture were evaluated. We included 42 horses (30 Thoroughbreds, 12 Quarter Horses), most of which were 3-5-y-old. Catastrophic radial fracture was observed in 30 (71%) horses; in the remaining 12 (29%) horses, the fracture of the radius was considered an incidental finding. All of the catastrophic radial fractures were complete, displaced, and comminuted; 70% were articular and 30% were non-articular; 61% were open and 39% were closed; 83% were diaphyseal to distal epiphyseal and 17% were proximal epiphyseal. Nine of the 30 horses with catastrophic fracture had a preexisting periosteal callus associated with the main line of fracture. Among Quarter Horse racehorses, the frequency of callus in radial fractures tended to be higher (p = 0.083) in 3-y-olds compared with other ages. In 6 of these 9 cases, the callus was located along the cranial aspect of the distal third of the diaphysis. All incidental cases consisted of osteochondral fragmentations, which occurred most frequently on the cranial border of the intermediate facet of the distal articular surface of the radius. Knowledge of the common sites of stress fractures or osteochondral stress remodeling in the radius can help to focus autopsies and to improve the characterization and interpretation of those lesions.","PeriodicalId":17579,"journal":{"name":"Journal of Veterinary Diagnostic Investigation","volume":" ","pages":"10406387251336267"},"PeriodicalIF":1.2,"publicationDate":"2025-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144698913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aimed to elucidate the role of wild rats in transmitting Leptospira to stray cats and dogs in Malaysia. We tested sera from 124 wild rats with the microscopic agglutination test (MAT): 88 of 122 (72%) sera were positive (titer ≥1:100), with the predominant serovars Icterohaemorrhagiae, Bataviae, Ballum, Javanica, Lai, and Pomona. With a Leptospira-specific PCR assay, we detected pathogenic Leptospira spp. in 33 of 124 (27%) kidney samples and 13 of 79 (16%) urine samples. Isolates obtained by culture of rat kidney and urine were identified to the species level with MAT using hyperimmune sera and the PCR assay. From 29 isolates, 2 pathogenic species were identified: L. interrogans serovar Bataviae and L. borgpetersenii serovar Javanica. Phylogenetic analysis using partial 16S rDNA sequences of the Leptospira spp. from the wild rats indicated that the species were similar to isolates from stray cats and dogs in previous studies. We confirmed that wild rats carried pathogenic Leptospira spp. and were a potential source of leptospiral infection of stray cats and dogs in Malaysia.","PeriodicalId":17579,"journal":{"name":"Journal of Veterinary Diagnostic Investigation","volume":" ","pages":"10406387251355254"},"PeriodicalIF":1.2,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12267210/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144642877","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}

Therefore, molecular sexing is a valuable tool for breeding, selection, and conservation purposes. We compared DNA extraction by commercial kit and an alkaline method from feathers, then developed a molecular method for sexing these species using the P2/P8 and CHD1F/CHD1R primer pairs. Both protocols were successful in extracting DNA; the alkaline method is more cost-effective, whereas the commercial kit protocol is easier to standardize. All DNA samples were successfully amplified using both the P2/P8 and CHD1F/1R primer pairs. The use of the CHD1F/1R primer pair is notably advantageous as it produces fragments of different lengths of the sex chromosomes, making them easily distinguishable via electrophoresis. The sequence analysis of the amplicons obtained with the CHD1F/1R primer pair revealed specific single-nucleotide polymorphisms for song thrush and redwing, which could be used as markers to differentiate between the 2 species if required.","PeriodicalId":17579,"journal":{"name":"Journal of Veterinary Diagnostic Investigation","volume":" ","pages":"620-624"},"PeriodicalIF":1.2,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11904919/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143605381","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}

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":"674-678"},"PeriodicalIF":1.2,"publicationDate":"2025-07-01","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}

Biopsy specimens were examined from an 11-y-old, spayed female, domestic shorthair cat with a 1-2-mo history of vomiting and anorexia, abdominal lymphadenopathy, and multiple hepatic nodules. Microscopically, the liver nodules and enlarged mesenteric lymph node had profound eosinophilic inflammation and sclerosis characteristic of FESF; the stomach, duodenum, jejunum, and ileum were unremarkable. Immunohistochemistry (IHC) was performed to further characterize the cell populations. Increased intralesional mesenchymal cells, interpreted as reactive fibroblasts, were positive with antibodies against smooth muscle actin (SMA), indicating a myofibroblast phenotype. Abundant intralesional macrophages were ionized calcium-binding adapter molecule 1 (IBA1) immunolabeled. Dual IHC of SMA and IBA1 revealed several double-positive mesenchymal cells, suggesting macrophage-to-myofibroblast transition (MMT). Our findings underscore the important role of macrophages not only in chronic inflammation, but also in tissue repair and fibrosis. Our case was a unique presentation of FESF with primary liver and mesenteric lymph node involvement, and without overt gastrointestinal lesions. Additionally, to our knowledge, myofibroblast phenoconversion and MMT have not been reported previously in cats, giving new insights to the pathogenesis of this poorly understood disease entity.","PeriodicalId":17579,"journal":{"name":"Journal of Veterinary Diagnostic Investigation","volume":" ","pages":"705-711"},"PeriodicalIF":1.2,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12075169/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144015512","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}

We assessed urine as a sample for heartworm antigen detection in dogs with known and unknown infection status using a commercial ELISA. Twenty-nine matching serum or plasma and urine samples were collected from 20 experimentally infected dogs to assess antigen detection in urine. Matching serum and urine samples of 267 dogs admitted to a spay/neuter clinic with unknown infection status were also screened. In experimentally infected dogs, antigenemia was detected in 86% of samples pre-ICD and 91% post-ICD; antigenuria was detected in 76% pre-ICD and 72% post-ICD; differences were not statistically significant. In clinic samples, antigenemia was detected in 7.9% of dogs pre-ICD and 12.4% post-ICD; antigenuria was detected in 11.6% of dogs pre-ICD and 6.4% post-ICD. In experimental infection samples, sensitivity (Se), specificity (Sp), and positive predictive value of antigenuria were high (85%, 100%, 100%, respectively). In clinic samples, Se and negative predictive value were high (95% and 92%, respectively). Our data confirm that heartworm antigen can be detected in the urine of dogs with both experimental heartworm infections and with unknown infection status.
