Maximum likelihood phylogenetic tree constructed based on partial BLV env sequences identified in geographical locations around the world. A maximum likelihood (ML) phylogenetic tree was constructed based on sequences from known BLV strains, representing ten different BLV genotypes derived from viruses isolated worldwide. Nucleotide sequences were obtained from the GenBank nucleotide sequence database. Sequences are labeled with their accession numbers and countries of origin. Genotypes are indicated by numbers to the right of the figure. One thousand replications were performed to calculate bootstrap values (indicated on the tree). The bar at the bottom of the figure indicates evolutionary distance
