Abstract
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
