Phylogenetic analyses of HIV-1 genome of the four patients, controls and reference sequences. Sequences LC1 to LC32 in env tree and gag tree indicate randomly selected unrelated CRF01_AE local control sequences. Sequences CON01 to CON30 in pol tree indicate randomly selected CRF01_AE control sequences from NCBI GenBank. The HIV-1 reference sequences retrieved from NCBI GenBank. Phylogenetic trees based on the partial sequence of the env C2V3V4 region (left), gag p17/p24 junction (middle) and a partial of pol gene (right) of HIV-1 genome were constructed by using the neighbor-joining method under the Kimura two-parameter model. The number at the node indicates the bootstrap values.
