Global maximum likelihood phylogenetic tree of CRF02_AG. The phylogenetic analysis is based on an alignment of 774 HIV-1 CRF02_AG polymerase (pol) nucleotidesmferred with 69 pol sequences from Bulgaria, 50 from persons who inject drugs (PWIDs) and 19 heterosexual (HET) individuals and 2933 pol sequences of the respective CRF available in GenBank using FastTree. Confidence values of tree branches and clusters were assessed by using the Shimodaira-Hasegawa test and are given as probabilities. Black and blue branches indicate globally distributed and Bulgarian pol sequences, respectively. Solid and dashed purple arrows indicate positions of Bulgarian PWID and HET only pol sequences in the tree, respectively.
