摘  要：
为了解青海牦牛中牛病毒性腹泻病毒和牛传染性鼻气管炎病毒的流行与分布情况,采用RTW-PCR/PCR和ELISA方法分别对青海省不同地区的252份牦牛血清样品进行了BVDV和IBRV抗原与抗体检测,为青海牦牛的综合防控措施提供了基本数据支持,为BVDV和IBRV的流行病学调查丰富了资料。结果表明所有被检地区都存在BVDV感染,地区阳性率100%,而IBRV地区阳性率为62.5%;BVDV抗原阳性率在6.45%至37.50%之间,总阳性率为21.83%;IBRV抗原阳性率在3.22%至25.81%之间,总阳性率为13.89%;BVDV/IBRV混合感染阳性率为3.57%;BVDV抗体阳性率在6.45%至43.75%之间,总阳性率为23.02%;IBRV抗体阳性率在3.23%至32.26%之间,总阳性率为14.29%;同时部分地区存在BVDV持续感染牛和IBRV潜伏感染牛,分别占样品总数的0.40%和0.79%。研究表明,青海省不同地区的牦牛均存在BVDV、IBRV的感染,且部分地区感染较为严重。

摘  要：
In order to investigate the prevalence and distribution of bovine viral diarrhea virus and infectious bovine rhinotracheitis virus in Qinghai yak,this study used RT-PCR/PCR molecular biology method and ELISA immunology method to detect BVDV and IBRV antigen and antibody from 252yaks' serum samples in different regions of Qinghai province.The results showed that BVDV existed in all the samples collected,with a positive rate of 100%,while the positive rate of IBRV was 62.5%;the positive rate of BVDV antigen was between 6.45%to 37.50%,with a total positive rate of 21.83%;the positive rate of IBRV antigen was between 3.22%to 25.81%,the total positive rate was 13.89%;the mixed infection of BVDV/IBRV antigen positive rate was 3.57%;the positive rate of BVDV antibody was between 6.45%to 43.75%,the total positive rate was 23.02%;the positive rate of IBRV antibody between 3.23% to 32.26%,the total positive rate was 14.29%;meanwhile in some areas there existed BVDV persistently infected cattle and IBRV latent cattle,accounting for 0.40% and 0.79% of the total samples respectively. This study shows that Qinghai yaks from different regions have BVDV and IBRV infection,and in some areas the infection is more serious,which provides the basic data for the comprehensive prevention and control of the viruses in Qinghai yak,and enriches the data for BVDV and IBRV epidemiological investigation in China.
