A total of 110 quarters of 28 healthy Holstein milking cows were used for the TCS and collection of milk samples. Milk samples were analyzed for SCC, antimicrobial components (S100A7 and lingual antimicrobial peptide (LAP)), and acute phase protein (serum amyloid A (SAA)). Milk samples with SCC of at least 105 cells/mL were cultured to isolate and identify the causative organism. A total of 110 teats were classified, TCS of 1, 2, 3, 4 in 60.9% (67), 26.4% (29),11.8% (13) and 0.9% (1) teats, respectively. A positive correlation (r=0.6915, P<0.0001) was found between the TCS and SCC in all teats. Pathogens were detected in 100% of milk samples from TCS ≥3 milk and 91% of those from TCS 2. However, pathogens were detected in only 33% of milk samples from TCS 1, a significantly (P<0.0001) lower detection rate than those from TCS 2 and ≥3. The LAP concentration in the group with detected pathogen was significantly (P<0.01) higher than that in the no growth group. The results suggest that in quarters with higher TCS, SCC and LAP concentrations were significantly higher, milking it easier to detect pathogens due to the greater likelihood of bacterial invasion.","PeriodicalId":49959,"journal":{"name":"Journal of Veterinary Medical Science","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143617668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, a medium that can selectively grow E. albertii and differentiate it from E. coli is earnestly desired. Here, we describe the evaluation of a recently developed selective differential medium, called cefixime-tellurite-phosphate-xylose-rhamnose-MacConkey (CT-PS-XR-MacConkey) medium, which enables the specific growth of E. albertii and differentiation of E. albertii (colorless) from E. coli (red) based on colony color and thus, facilitating the efficient isolation of E. albertii from diarrheal stool. When three E. albertii negative diarrheal stools were inoculated onto CT-PS-XR-MacConkey and xylose-rhamnose-melibiose (XRM) containing MacConkey agars, no colorless colonies were observed on both the media. However, when E. albertii was spiked into these three diarrheal stools, the ratio of colorless colonies to red colonies was higher on CT-PS-XR-MacConkey agar compared to XRM-MacConkey agar in all three samples. Notably, out of 105 Eacdt-gene PCR negative diarrheal stools 56 yielded colorless colonies on MacConkey agar while out of these 56 diarrheal stools, nine yielded colorless colonies on XRM-MacConkey but no colorless colonies were observed on CT-PS-XR-MacConkey agar. Furthermore, evaluation of these two media with five E. albertii positive-stool specimens revealed that the number of red colonies were constantly less, whereas that of colorless colonies were constantly more on CT-PS-XR-MacConkey agar, thus aiding in efficient isolation. Altogether, these results suggest that the CT-PS-XR-MacConkey agar could be a useful selective differential medium for isolation of E. albertii from diarrheal stool specimens.","PeriodicalId":49959,"journal":{"name":"Journal of Veterinary Medical Science","volume":" ","pages":"308-314"},"PeriodicalIF":1.1,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11903357/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143048663","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}

Freshwater Lymnaea snails serve as intermediate hosts, contributing to the increasing prevalence of fascioliasis in cattle in coastal areas. The salinity tolerance of Lymnaea snails was investigated along with their distribution and Fasciola infection rates in both snails and grazing cattle in Ben Tre, Tra Vinh, and Soc Trang provinces in Mekong Delta, Vietnam, where seawater reversely enters into the paddy field during the dry season. Lymnaea snails were collected from 53 communes across the three provinces and analyzed for Fasciola larval infections. Additionally, cattle fecal samples were examined for the presence of Fasciola eggs. The salinity levels in the study areas ranged from 0.03% to 1.90%. In total, 1,152 Lymnaea snails including L. viridis and L. rubiginosa were collected. The maximum salinity levels of L. viridis and L. rubiginosa habitats were 0.64% and 0.74%, respectively. The Fasciola infection rates of L. viridis were 2.0% in low-salinity areas and 3.7% in high-salinity areas, whereas no L. rubiginosa infections were detected in either salinity area. The prevalence of cattle fascioliasis in high-salinity areas (35.7%) was similar to low-salinity areas (32.9%). This study is the first to demonstrate that L. viridis can thrive and sustain Fasciola transmission under high-salinity conditions, suggesting the salinity tolerance of these intermediate host snails as a key factor contributing to the expansion of fascioliasis in high-salinity coastal areas.","PeriodicalId":49959,"journal":{"name":"Journal of Veterinary Medical Science","volume":" ","pages":"291-300"},"PeriodicalIF":1.1,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11903356/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143068887","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}

Eleven samples tested positive for E. intestinalis, two from M. tridactyla (2/56, 3.6%), seven from E. sexcinctus (7/51, 13.7%), two from P. maximus (2/11, 18%) and one from C. squamicaudis (1/3, 33.3%). There was a predominance of positive results in adult animals, of both sexes across and in the Pantanal and Cerrado biomes. In conclusion, the prevalence in Xenarthra was 9.4%, with a higher occurrence in armadillos than in anteaters.
