| genetic and antigenic characterization of bovine viral diarrhea viruses isolated from cattle in hokkaido, japan. | in our previous study, we genetically analyzed bovine viral diarrhea viruses (bvdvs) isolated from 2000 to 2006 in japan and reported that subgenotype 1b viruses were predominant. in the present study, 766 bvdvs isolated from 2006 to 2014 in hokkaido, japan, were genetically analyzed to understand recent epidemics. phylogenetic analysis based on nucleotide sequences of the 5'-untranslated region of viral genome revealed that 766 isolates were classified as genotype 1 (bvdv-1; 544 isolates) and g ... | 2016 | 26400674 |
