ML tree reconstruction for gag (a), pol (b), and env (c) gene fragments. Viral sequences from query sequences (P1, P2 and P3), local control sequences and database subtype CRF01_AE controls (DBCs) and CRF01_AE reference sequences are colored differently. Subtype A reference sequences, shown in dark cyan, were used as an outgroup for the rooting of phylogenetic trees. Node support values are indicated on the case sequences. ML, maximum-likelihood; DBC, database controls; HZC, local controls
