A Phylogenetic tree of HIV-1 pol gene. Sample sequences have red shapes. The sequences were aligned using ClustalW, and phylogenetic analysis performed using the neighbor-joining method of MEGA.v.7 software with Bootstrap value of 1000 replicates. The reference sequences were taken from the Los Alamos database (the subtype precedes the country letters code and reference accession number). Some references have been omitted to enable better visualization of the sample sequences. Abbreviation: CRF; circulating recombinant form, cpx; complex
