seroprevalence of bovine viral diarrhea infection in yaks (bos grunniens) on the qinghai-tibetan plateau of china.the seroprevalence of bovine viral diarrhea virus (bvdv) infection in yaks was investigated in qinghai and tibet of china during the year 2011. a total of 549 (tibet 287, qinghai 262) serum samples was collected from tibet and qinghai and were examined for bvdv p80 antibody by elisa. the results of the experiment showed that 145 (53.65 %) of tibetan samples and 189 (72.14 %) of qinghai's samples were positive for bvdv. the observations of the present study suggest that bovine viral diarrhea is c ...201323111636
molecular investigation of bovine viral diarrhea virus infection in yaks (bos gruniens) from qinghai, china.bovine viral diarrhea virus (bvdv) is a pestivirus which infects both domestic animals and wildlife species worldwide. in china, cattle are often infected with bvdv of different genotypes, but there is very limited knowledge regarding bvdv infection in chinese yaks and the genetic diversity of the virus. the objectives of this study were to detect viral infection in yaks in qinghai, china and to determine the genotypes of bvdv based on analysis of the 5'untranslated region (5'utr) and n-terminal ...201424524442
