| Abstract: | Nucleotide sequence of a section of the Env 105 gene of bovine leukemia provirus isolates, obtained from farm animals in different regions of Russia, was determined. Conducted phylogenetic analysis has allowed us to assess heterogeneity of the studied population of the bovine leukemia virus (BLV). Based on results of BLV genetic diversity, four virus’s genotypes—I, II, IV, and VII with dominating genotype IV—were detected. |
