【 摘 要 】
To understand how the latest dominant bovine leukemia virus (BLV) strains were introduced and spread in the Miyazaki prefecture, we collected blood samples from 3 geographic areas (north, central and south) and carried out sequence analysis of the BLV env gene. Two genotypes, genotype I, and III, were identified and the majority of the strains belonged to genotype I (71/74). To clarify a route of BLV introduction, we divided the strains into 20 subgenotypes based on their nucleotide sequences and performed phylogenetic analysis. Our study indicated that common BLV strains were comparatively evenly distributed even in the area, where the farmers have not introduced cattle from other areas and the cattle have limited exposure to BLV infection in grazing fields.
