摘　　要：应用ELLSA试验对来自内蒙古地区17个大﹑中﹑小型奶牛场的2 391份牛血清样品进行了牛病毒性腹泻/黏膜病抗体检测,并对其中222份抗体阴性牛应用ELISA试验进行牛病毒性腹泻/黏膜病的抗原检测。结果表明:17个奶牛场均检出BVDV抗体阳性,共检出阳性血清2 125份,阳性率最高达100%,最低为46.8%,平均为88.9%。对14个奶牛场进行了BVDV抗原检测,在5个奶牛场检出BVDV抗原阳性,阳性率为3.6%(8/222)。表明内蒙古地区奶牛场普遍存在牛病毒性腹泻/黏膜病感染,感染率较高,并且牛群中存在持续性感染(PI)牛。2 391 bovine serum samples were collected from 17 dairy farms of Inner Mongolia to detect the antibody level of bovine viral diarrhea-mucosal disease by ELISA. The antigen detection of bovine viral diarrhea-mucosal disease was made on 222 antibody-negative serum samples by ELISA. The results showed that positive BVDV antibody was detected in 17 dairy farms. And there were 2 125 positive serum samples,and the highest positive rate was 100%and the lowest positive rate was 46.8%and the average positive rate was 88.9%. BVDV antigens in 14 dairy farms were detected and that in 5 dairy farms were positive. The positive rate was 3.6%（8/222）. It was shown that the bovine viral diarrhea generally existed in dairy farms of Inner Mongolia with higher infection rate. And persistent infection （PI） cattle were existed in cow herd.
