Analysis on the Prevalence of Yak Pasteurellosis and Bovine Viral Diarrhea in Shigatse City
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.
