Abstract

As part of an ongoing molecular epidemiological investigation of human immunodeficiency virus type 1 (HIV-1) in rural Georgia, the 5′ half of reverse transcriptase (RT) genotypes from 30 patients was sequenced and phylogenetically analyzed. Two patients, GA132 and GA169, were infected with pol sequences of non-B subtype origin that were found to cluster phylogenetically with subtype A-E of Thai origin. Sliding window bootstrap analysis of GA169 showed clear evidence of A/B recombination within the pol gene segment, whereas in the other patient, GA132, no break point within RT could be identified. Interestingly, pairwise comparisons between these 2 patients' C2-V3 env region revealed a 13.5% divergence. However, similar comparisons within the non-B pol segments yielded a 1.23% nucleotide divergence, which suggests a complex phylogenetic and epidemiological history of the subtype A pol genotype in this region. These data demonstrate an increasing diversity of HIV-1 subtypes and the potential emergence of previously unidentified HIV-1 A-E/B recombinants in the rural United States.
