Phylogenetic classification of 14 HIV-1 isolates from pregnant women in PR and TR genes: (●) HIV-1 sequences without drug resistance mutations; (▲) HIV-1 sequences with TDR mutations. Recombinant HIV-1 sequences were excluded from the phylogenetic analysis. Brackets indicate different monophyletic clusters. Bootstrap values (1000 replicates) above 70% are shown. GenBank accession numbers of reference sequences are: Subtype B (AY173956, K03455, AY781126; AB287365; AY037269), Subtype F1 (AF077336; AF005494; FJ771010; JX140671), and Subtype C (U52953; AF286228; AY727524; AY703911; AB254142). The tree was rooted using the simian immunodeficiency virus sequence from chimpanzee (SIVcpz, GenBank accession number: AF103818) as an outgroup.
