Figure 1.
Phylogenetic tree of the HIV-1 pol regions at nucleotide level aligned with reference sequences from the Los Alamos database (http://www.hiv.lanl.gov). Bootstraps values (1000 replicates) >70% are shown. Current isolates are designated as ETH-G-followed by 4 digit number and the rest are reference sequences. Keys: ●: Confirmed monophyletic groups come from one Muslim man who had married with two women. ►: Confirmed monophyletic groups come from another heterosexual couple. Reference sequences: HIVU46016 (C-Ethiopia), AY772699 (C-S. Africa), AF067155 (CIndia), HIVU52953 (C-Brazil), AX149771 (BC-China) and the rest references sequences are non C.
