[genome sequencing and analysis of the bovine viral diarrhea virus-2 strain jz05-1 isolated in china].bovine viral diarrhea virus (bvdv) is a member of the genus pestivirus, which is a widespread problem for beef and dairy herds, and has given rise to a significant loss in the livestock industry all over the world. the bvdv strain jz05-1 isolated from cattle in jilin, china generated cytopathic effect (cpe) in mdbk cells. eight overlapped gene fragments were amplified by rt-pcr and sequenced, the complete genom sequence of bvdv strain jz05-1 was assembled. according to the results, the jz05-1 ge ...201020572347
isolation and identification of a bovine viral diarrhea virus from sika deer in china.bovine viral diarrhea virus (bvdv) infections continue to cause significantly losses in the deer population. better isolation and identification of bvdv from sika deer may contribute significantly to the development of prophylactic therapeutic, and diagnostic reagents as well as help in prevention and control of bvdv. however, isolation and identification of bvdv from sika deer is seldom reported in literature. in this study, we collected some samples according to clinical sign of bvdv to isolat ...201121352530
herd-level prevalence and associated risk factors for toxoplasma gondii, neospora caninum, chlamydia abortus and bovine viral diarrhoea virus in commercial dairy and beef cattle in eastern, northern and northeastern china.although the seroprevalence of toxoplasma gondii, neospora caninum, chlamydia abortus and bovine viral diarrhea virus infection in cattle have been reported in some areas in china, most of them were conducted with small number of cattle samples and very limited districts and neglected the assessment of herd management factors associated with herd-level prevalence of these pathogen infections. thus, from september 2013 to december 2014, a large-scale seroprevalence study was conducted to determin ...201526231838
genetic characterization of a noncytopathic bovine viral diarrhea virus 2b isolated from cattle 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, n(pro), e1 and e2 gene demonstrated the virus belonged to bvdv 2b, and genetically related to the bvdv strain hokudai-lab/09 ...201424811746
