From: Molecular and phylogenetic analysis of HIV-1 variants circulating in Italy
Phylogenetic classification of the C2-V3 env region. The C2-V3 env region of Italian samples has been aligned with standard sequences of HIV-1 group M including some known CRF. Sequences from groups N and O have been used as outgroup. Italian sequences are indicated as underlined. Reliability has been estimated by boot-strap analysis. The bar shows a 10% divergence.
