Abstract
In January 2013, several clinical signs of cattle with diarrhea, cough, nasal discharge, and fever were reported in Jilin province, China. One virus named SD1301 was isolated and identified. Complete genome of the virus is 12258nt in length and contains a 5′UTR, one open reading frame encoding a polyprotein of 3,897 amino acids and a 3′UTR. Phylogenetic analysis of 5′UTR, Npro, E1 and E2 gene demonstrated the virus belonged to BVDV 2b, and genetically related to the BVDV strain Hokudai-Lab/09 from Japan in 2010. This bovine viral diarrhea virus displays a unique genetic signature with 27-nucleotide deletion in the 5′UTR, which is similar to the bovine viral diarrhea virus C413 (AF002227). This was the first confirmed isolation of ncp BVDV2b circulating in bovine herd of China.Keywords
