title: Seroprevalence of bovine viral diarrhea infection in Yaks (Bos grunniens) on the Qinghai-Tibetan Plateau of China.
abstract: 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 common in yaks in Tibet and Qinghai, China.
