Bovine viral diarrhea virus (BVDV) causes serious economic losses. BVDV has high genomic diversity: two viral diarrhea virus genotypes, with twentyone subgenotypes for BVDV-1 and four subgenotypes for BVDV-2. Vac-cines are important tools for reducing the economic losses caused by this virus. However, the strains of the vaccine match the antigenic profile of the viruses circulating in the area where the vaccine is. A phylogenetic study of 13 virus isolates circulating in the territory of the Republic of Belarus showed that the genetic profile of BVDV consisted in the overwhelming majority of subtypes BVDV-1f (76.9 %) and BVDV-1a (15.0 %), genotype 1, in one farm the subtype was found BVDV-2a genotype 2. |
