We immunized BALB/c mice with inactivated and purified BoAHV1 to prepare hybridoma cells. After the successful establishment of a positive hybridoma cell line, co-immunoprecipitation coupled with mass spectrometry unveiled the predominant targeting of glycoprotein B (gB) by the hybridoma cells. Through bioinformatics analysis and Western blot techniques, we identified the epitope of the monoclonal antibody (mAb) against gB to amino acids 1-170. Subsequently, the 1H3 mAb was leveraged for the development of a gB blocking ELISA (gB-bELISA), utilizing inactivated BoAHV1 virions as the coating antigen. The optimized protocol involved diluting samples 2-fold with 1% fish gelatin, followed by incubation periods of 120 min for samples, 30 min for HRP-conjugated 1H3 mAb, and 15 min for the TMB substrate. We validated our assay using 268 bovine serum samples with clear backgrounds and established the cutoff value of 43.8% through ROC analysis. Additionally, we tested 256 clinical bovine serum samples using both our gB-bELISA and a virus neutralization test, achieving a concordance rate of 95.3%. Based on testing 495 randomly selected sera from 18 counties for BoAHV1 antibodies with our gB-bELISA, the seroprevalence of IBR in the Central China region was 22.0% (95% CI: 18.4, 25.7). Our gB-bELISA could be a valuable tool for the clinical detection of IBR, supporting disease control and eradication efforts.","PeriodicalId":17579,"journal":{"name":"Journal of Veterinary Diagnostic Investigation","volume":" ","pages":"10406387251346909"},"PeriodicalIF":1.2,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12176781/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144326161","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}

Processing fluids (PFs) are an increasingly popular sample type for PRRSV surveillance due to their cost-effectiveness and high herd-level sensitivity. However, like other aggregate sample types, PF samples are non-pristine, and the RNA within them is susceptible to degradation, increasing the risk of false-negative and/or inconsistent results in reverse-transcription real-time PCR (RT-rtPCR) testing. We evaluated the efficacy of the nucleic acid-preserving reagent PrimeStore molecular transport medium (PS-MTM) in improving PRRSV RT-rtPCR detection rates, Ct values, and whole-genome sequencing (WGS) outcomes in PF samples. We collected PF samples from 2 PRRSV-positive sow herds and divided them into untreated controls and 2 PS-MTM-treated groups. PS-MTM-treated PFs had significantly lower Ct values compared to untreated samples, indicating improved RNA preservation and detectability. Although sequencing outcomes varied between study groups, PS-MTM-treated samples had statistically higher unique read counts. However, differences in other measured sequencing outcomes between the study groups were not statistically significant. PS-MTM has potential in PF sampling protocols to enhance PRRSV surveillance accuracy by reducing false-negative RT-rtPCR results.","PeriodicalId":17579,"journal":{"name":"Journal of Veterinary Diagnostic Investigation","volume":" ","pages":"10406387251348464"},"PeriodicalIF":1.2,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12162531/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144275230","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}

Here, we review 18 diseases that occur in the nervous system of equids in Brazil, including some critical infectious diseases (rabies, equine encephalomyelitides, equine herpesviral myeloencephalopathy, protozoan myeloencephalitis), and diseases caused by toxic plants and mycotoxins. Our review provides reference data to assist pathologists and clinicians in diagnosing neurologic diseases in equids.

Histologic lesions typical of FIP (vasculitis and pyogranulomatous inflammation) were present in the kidneys and retroperitoneal fat of 4 cases, and in 3 cases, FCoV antigen was demonstrated in the regions of hemorrhage. The exact mechanism of this hemorrhage is unknown, but we speculate that vasculitis caused by FIP is the cause.
