| characterization of a bovine viral diarrhea virus originated from cattle in gansu province, china. | a bovine viral diarrhea disease virus (bvdv) gs-4 was isolated in western china form dairy cattle with respiratory disease. genomic comparison analysis with the 5' half genome sequence encompassing the coding region of n(pro), capsid, and envelope glycoproteins showed that the gs-4 should be classified into bvdv-1b1, which is considered as one of the predominant subgenotypes found in china. this classification was confirmed by phylogenetic analysis based on e2 coding region. | 2013 | 23681710 |
