genetic characterization of bovine viral diarrhea virus strains in beijing, china and innate immune responses of peripheral blood mononuclear cells in persistently infected dairy acquire epidemiological data on the bovine viral diarrhea virus (bvdv) and identify cattle persistently infected (pi) with this virus, 4,327 samples from holstein dairy cows were screened over a four-year period in beijing, china. eighteen bvd viruses were isolated, 12 from pi cattle. based on genetic analysis of their 5'-untranslated region (5'-utr), the 18 isolates were assigned to subgenotype bvdv-1m, 1a, 1d, 1q, and 1b. to investigate the innate immune responses in the peripheral-blood mo ...201526119170
genomic characterization of three bovine viral diarrhea virus isolates from cattle.three strains of the bovine viral diarrhea virus (bvdv) were isolated from cattle in beijing, china. to investigate their genomic features, we sequenced and characterized the complete genome of each of the isolates. each of the three virus genomes is about 12,220 bp in length, containing a 5' untranslated region (utr), one open reading frame (orf) encoding a 3897-amino-acid polypeptide, and a 3' utr. the nucleotide sequence of the three isolates were 99.0 % identical to each and other shared nuc ...201627613287
