FIG 3.

Maximum likelihood phylogenetic tree of p24 Gag proviral sequences of HIV-1 group M, N, P, and O. The C clade sequences are shown in purple (n = 138), B clade sequences are in blue, and A clade sequences are in green. Subjects recruited in our cohort are numbered with the prefix “IN” and highlighted with dots. Reference Indian sequences randomly selected from 1993 to 2002 are highlighted in purple. Other reference sequences are shown in black. All of the reference sequences are from the Los Alamos database (http://www.hiv.lanl.gov/).
