我国部分地区牛传染性鼻气管炎血清学调查与分析

摘要

In order to understand the infection status and epidemic trend of infectious bovine rhinotracheitis (IBR)in pastoral and semipastoral provinces of china,this study used ELISA kit to detect antibodies from 9 668 bovine serum samples collected from 11 provinces.The results showed that the IBR antibodies were detected in all provinces.The average positive rate of individuals was 52.77%,and the positive rate of group was above 80% for 3 consecutive years,which showed that infections were common.The infection of cows was more serious than taht of beef and dual-purpose cattle.Meanwhile,we found that mixed infection of IBRV and BVDV was more common in production practice.The epidemiological investigation revealed the basic situation of the IBR infection in pastoral and semipastoral provinces of China and provided a reference for the development of scientific prevention and control policy.%为了解我国牛传染性鼻气管炎的感染情况及流行趋势,对2014年-2016年采集于11个牧区半牧区省份的9668份牛血清样品进行了牛传染性鼻气管炎病毒抗体检测.结果显示,牛传染性鼻气管炎病毒抗体的个体平均阳性率为52.77%,群体阳性率连续3年均在80%以上,说明感染现象较为普遍.乳用牛的感染情况较肉用牛和乳肉兼用牛严重.同时,发现生产实际中牛传染性鼻气管炎与牛病毒性腹泻混合感染情况普遍.此次摸底调查掌握了我国牛传染性鼻气管炎感染情况,为制定科学防控政策提供了参考依据.
