Figure 2From: Prevalence of human papillomavirus infection and phylogenetic analysis of HPV-16 E6 variants among infected women from Northern BrazilHPV-16 phylogenetic tree based on E6 sequencing. A phylogenetic tree was constructed using the RaxML program. This is a bootstrapped (1.000 replicates) consensus Maximum-Likelihood tree. PPH16 – GenBank accession number K02718 (HPV-16R). American branch (light blue) includes North American (NA) and Asian-American (AA) variants.Back to article page
