Abstract: The complete genomic sequencing and characterization of Bovine viral diarrhea virus (BVDV) isolate XJ-04 originated from cattle in China was described. The genomic RNA of the isolate was 12,284 nt long and contained short 5'- untranslated region (UTR), 3'-non-coding regions (NCR), and one open reading frame (ORF) encoding a large polyprotein of 3,895 amino acids with 20 potential N-glycosylation sites. The identity of the isolate XJ-04 with reference strains NADL (BVDV-1) and 890 (BVDV-2) in autoprotease (Npro) gene and structural genes (C, Erns, E1, E2) was analyzed. The percentage of nt and aa identity in analyzed genes indicated that the isolate XJ-04 was closer to the reference strain 890 (BVDV-2) than to NADL (BVDV-1). Phylogenetic analysis revealed that the isolate belonged to BVDV-2a subtype. Furthermore, comparison analysis indicated that the isolate XJ-04 did not contain any genomic insertions that can be directly related to the cytopathic phenotype.
