Phylogenetic tree developed by the neighbor-joining method with the substitution pattern maximum composite likelihood (Software Mega v. 5). The samples show identification Accession Number/country of study/genotype referring to the env gene. The numbers near each node represent the values ​ ​of 1000 bootstrap replicates, showing only those greater than 50%. The scale represents the number of replacements/sites.
