Summarized phylogenetic tree of 40 Sanandaj (SDJ) samples based on protease and reverse-transcriptase (PR-RT, 1017 bp) sequences.

<p>Tree was constructed using neighbor-joining method with 1000 replicates. As a summarized representation, only reference sequences from HIV-1 subtypes/CRFs previously reported in Iran including B (●; closed circles), D (□; open squares), A1 (■; closed squares), A2 (○; open circles), CRF01_AE (◆; closed diamonds) and CRF35_AD (▲; closed triangle) are included. GenBank accession numbers for the reference sequences, as well as, bootstrap values over 70% are shown. The scale bar represents nucleotidesubstitutions per site.
