From: The HIV-1 epidemic in Bolivia is dominated by subtype B and CRF12_BF "family" strains
Phylogenetic analysis of 51 HIV-1 pol (a) and 37 env (b) samples from Bolivia. Bootstrap values ≥70% supporting nodes are shown on the left of each node and were estimated using the neighbor-joining with Tamura-Nei substitution model. The scale bar indicates 10% nucleotide sequence divergence. HIV-1 samples analyzed in the present study were in bold format. Arrows indicate those samples with intergenic recombination. Highly supported (> 95%) monophyletic clusters are highlighted and numbered.
