Figure 3. Neighbor-joining trees of HIV-1 env C2-V5 sequences individually from six inoculum and transmission pairs.

Figure 3

Aligned nucleotide sequences for six inoculums and transmitted variants were used to generate neighbor-joining trees for individual viral pairs. (A) HIV-1 subtype B, IIIB; (B) HIV-1 subtype B, BAL; (C) HIV-1 subtype B, clinical isolate 074; (D) HIV-1 subtype B, clinical isolate 015; (E) HIV-1 subtype A, RW92008; (F) HIV-1 subtype C, IN93999. White circles: the sequences of the inoculum viruses; black circles: the sequences of the transmitted viruses.
