摘　　要：为掌握日喀则市牦牛巴氏杆菌病和牛病毒性腹泻病的流行情况,研判当前该区域内牦牛发病趋势,为进一步优化当前区域内牦牛疫病防控策略提供依据和建议。针对区域内牦牛个体进行抽样,用实验室检测技术开展牦牛巴氏杆菌抗体、牛病毒性腹泻病毒抗原、细菌培养鉴定、病原核酸检测等项目。针对疑似发病个体开展相关病原学检测,结合当地动物疫病防控工作历史经验,对检测结果进行研究分析。随机抽样检测结果显示,牦牛巴氏杆菌病抗体阳性率12.43%,牛病毒性腹泻抗原阳性率9.04%,牛巴氏杆菌细菌培养分离鉴定阳性率为0,牛巴氏杆菌核酸检测阳性率为0,牛病毒性腹泻核酸检测阳性率为0;发病牛群采样检测结果显示10头牛感染牛病毒性腹泻病毒,其中2头可能同时感染牛巴氏杆菌病。结果表明牦牛巴氏杆菌病以及牛病毒性腹泻在相关区域内广泛存在,牛病毒性腹泻病毒感染是导致当前该区域牦牛发病的主要原因,要进一步加强牛巴氏杆菌病和牛病毒性腹泻病的鉴别诊断,优化调整当前疫病防控策略,转变传统防控思维,消灭相关病原传播的风险因素。To understand the prevalence of yak pasteurellosis and bovine viral diarrhea in Shigatse City,the current trend of yak diseases in this region was assessed,which provided a basis and suggestions for further optimizing the prevention and control strategies for yak diseases in this area.Samples were collected from individual yaks in the region.Laboratory detection techniques were employed to conduct tests such as detecting yak pasteurella antibodies,bovine viral diarrhea virus antigens,bacterial culture identification,and pathogen nucleic acid detection.Etiological detection was carried out on suspected diseased individuals.Combined with the historical experience of local animal disease prevention and control work,the test results were analyzed.The results of random sampling and detection showed that the positive rate of yak pasteurellosis antibodies was 12.43%,the positive rate of bovine viral diarrhea antigens was 9.04%,while the positive rates of bovine pasteurella bacterial culture isolation and identification,nucleic acid detection,and bovine viral diarrhea nucleic acid detection were both 0.The sampling and detection results of diseased cattle herds indicated that 10 cattle were infected with bovine viral diarrhea virus,and two of them might be simultaneously infected with yak pasteurellosis.Yak pasteurellosis and bovine viral diarrhea are widespread in related regions.Infection with bovine viral diarrhea virus is the main cause of yak diseases in this region.Therefore,it is necessary to further strengthen the differential diagnosis of yak pasteurellosis and bovine viral diarrhea,optimize and adjust the current disease prevention and control strategies,change the traditional prevention and control mindset,and eliminate the risk factors for the transmission of relevant pathogens.
