摘要: The identification and characterization of bovine viral diarrhea virus 2 (BVDV-2) strain SD-06 isolated from cattle in China is reported. We performed sequence analysis of 5'-untranslated region (5'-UTR) and E2 sequences and the identity at the nucleotide and amino acid level indicated that the isolate was closely related to BVDV-2. The BVDV-2 strain New York'93 showed the highest sequence homology with the isolate SD-06. The phylogenetic analysis revealed that the isolate SD-06 belonged to BVDV-2a subtype. Furthermore. immunofluorescence assay with the monoclonal antibody specific for BVDV-2 glycoprotein E2 confirmed this identification. Thus, the strain SD-06 was the first isolate of BVDV-2 identified in China.
