ABSTRACT The aim of this study was to characterize the HIV-1 intersubtype recombinant forms generated during the follow-up of a dual natural infection with subtypes B and G. Near full-length sequences from plasma and peripheral blood mononuclear cell (PBMC) compartments were analyzed and the biological characteristics of their derived primary isolates studied. Different mutations were detected in V1, V2, and V3 sequences from primary isolates but not in sequences from plasma RNA or PBMC DNA. The HIV-1 near full-length sequence from the first collected plasma was of subtype G and the presence of subpopulations of subtypes B and G was observed with subtype-specific primers for protease and reverse transcriptase segments. Subsequent sequences from plasma, PBMCs, and primary isolates were obtained during a follow-up of 6 years; all of them were BG recombinants and showed identical intersubtype breakpoints between subtypes B and G in pol and nef. The env sequence from all primary isolates harbored a unique insert of subtype B. Specific primers for the V3 loop identified fluctuating subtype B and/or subtype G sequences either from plasma RNA or PBMC DNA.
