Abstract
Nested RT-PCR was used to investigate bovine viral diarrhea virus in 511 specimens collected from Chinese pigs exhibiting clinical symptoms between 2007 and 2010. Of these, 137 samples were BVDV-positive and the BVDV prevalence rate was 23.1% (9/39) in 2007, 27.7% (44/159) in 2008, 33.6% (34/101) in 2009, and 23.6% (50/212) in 2010. Twenty of 137 BVDV-positive samples were used for further genetic analysis of the 5'-UTR. Phylogenetic analysis revealed that they were BVDV-1 and subtyped into BVDV-1a, BVDV-1b, BVDV-1m, BVDV-1o and an unknown subgenotype. This study showed that BVDVs were highly prevalent in Chinese pig herds and appropriate measures should be taken to control BVDV prevalence in pig herds.Entities:
