Serological assessments were conducted using the Rose-bengal test, serum agglutination test, competitive enzyme-linked immunosorbent assay and NH-AGID. <em>Brucella</em>-positive sera were further distinguished using differential identification ELISA and NH-AGID. Vaginal swab DNA was tested using AMOS-PCR and dual real-time fluorescence PCR. Results showed that NH-AGID demonstrated a high specificity and positive predictive values (PPV) for diagnosis of brucellosis. Additionally, the diagnostic accuracy of NH-AGID for infected and shedding animals was more than 90 %. Heifers vaccinated with A19-∆VirB12 were serologically confirmed as infected by NH-AGID and also tested positive by PCR. The application of NH-AGID effectively identified infected and shedding animals from vaccination with A19-∆VirB12, thereby supporting the brucellosis decontamination efforts.</div></div>","PeriodicalId":37152,"journal":{"name":"Veterinary and Animal Science","volume":"30 ","pages":"Article 100530"},"PeriodicalIF":1.9,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145424840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study developed a duplex crystal digital PCR (dPCR) assay for the differential detection of NDRV and MDRV. Primer pairs and probes were designed specifically for the S3 genome of NDRV and the S2 genome of MDRV. To evaluate the method's performance, different reaction conditions were optimized, focusing on specificity, sensitivity, and reproducibility. The results showed that duplex crystal dPCR could accurately and differentially detect NDRV and MDRV, with a detection limit as low as 1 × 10⁻¹ copies/μl. It did not cross-react with other avian viruses, including duck Tembusu virus (DTMUV), H5 subtype avian influenza virus (H5 subtype AIV), H7 subtype AIV, H9 subtype AIV, Newcastle disease virus (NDV), infectious bronchitis virus (IBV), Egg drop syndrome virus (EDSV), Contagious bursal disease virus (IBDV, B87 strain), and duck Plague virus (DEV). The method also demonstrated good reproducibility, with intra-assay and inter-assay coefficients of variation (CV) both less than 8 %. For clinical application, 299 samples from coastal areas of Guangxi, China were tested. Duplex crystal dPCR detected NDRV and MDRV positive rates of 8.027 % and 6.020 %, respectively, with a co-infection rate of 1.672 %. The kappa values between duplex crystal dPCR and duplex quantitative polymerase chain reaction (qPCR) were 0.977 for NDRV and 1 for MDRV, indicating strong agreement. These findings confirm that the established duplex crystal dPCR is a specific, sensitive, and accurate method for detecting and quantifying NDRV and MDRV.

For this study, 270 clinically healthy lactating goats were selected from three districts highly inhabited by goats. Data on the daily milk yield (DMY), udder height (UH), udder width (UW), udder circumference (UC), udder depth (UD), teat depth (TD), teat length (TL), distance between the teats (DBT), teat circumference (TC), udder distance from ground (UDG), and udder volume (UV) of lactating does were measured early in the morning and evening before kids sucking among lactation stages, dam parity, birth type, and sex of kids. Data were analyzed using ANOVA, correlation, regression, and multivariate analysis. Results indicated that DMY, udder, and teat morphometric traits were significantly (<em>p</em> &lt; 0.05) affected among the studied districts except UV. The lactation stage effect was significant (<em>p</em> &lt; 0.0001) on DMY and UC; however, the effect was non-significant for UD, UDG, and TD.

Evidence on the national pooled prevalence and risk factors of ruminant schistosomiasis in Ethiopia is limited, underscoring the need for further research to inform effective control strategies. This systematic review and meta-analysis was conducted in line with the PRISMA guidelines. An extensive review was conducted across five academic databases (PubMed, Google Scholar, ScienceDirect, Scopus, and Web of Science), with all searches completed between May 10, 2025, and June 1, 2025. Heterogeneity was assessed, and a random-effects model was used to determine the pooled prevalence of schistosomiasis in ruminants. The sources of variation were analyzed through subgroup analysis, meta-regression, and sensitivity analysis. Publication bias was assessed using funnel plots, Begg's test, and Egger’s test. A total of 33 studies were included in this meta-analysis, revealing a pooled prevalence of schistosomiasis in ruminants of 14.4 %, 95 % CI: [11.2-17.6]. The analysis demonstrated a substantial degree of heterogeneity among studies, with I² = 98.2 %, Q=1764.5 and p &lt; 0.001.
