牛副流感病毒3型流行现状分析OA

Bovine parainfluenza virus type 3(BPIV3)is an important pathogen causing bovine parainfluenza.Infection with BPIV3 can also cause immunosuppression,making cattle more susceptible to other infectious pathogens.Clinically,BPIV3 is often co-infected with bovine coronavirus,respiratory syncytial virus,and others,further worsening the symptoms.In recent years,the incidence and mortality of bovine respiratory disease have significantly increased,particularly among weaned or transported beef cattle,posing a serious threat to the cattle industry.Therefore,this article will systematically review the epidemiology of BPIV3 in China,analyze the epidemiological trends of different genotypes of the virus and seroepidemiological data,laying the foundation for formulating effective prevention and control strategies to ensure the healthy and sustainable development of the cattle industry.
