Phylogenetic clustering profile of the non-overlapped fragments assigned as subtype B from both plasma and provirus isolate 01BR_IMT_013 were compared to a number of additional Brazilian subtype B sequences and other HIV-1 reference sequences from the Los Alamos HIV-1 database representing 11 genetic subtypes.

<p>For purposes of clarity, the tree was midpoint rooted. The approximate likelihood ratio test (aLRT) values of ≥70% are indicated at nodes. The scale bar represents 0.05 nucleotide substitutions per site.
