Abstract

The reverse transcriptase (RT) enzyme of HIV type 1 (HIV-1) is largely targeted by the host immune selection pressure and would differ in the anatomical compartments, thereby having a drastic impact on viral quasi-species evolution. The HIV-1 RT region sequenced from plasma and genital secretions of 8 antiretroviral treatment (ART)-naive females was analyzed for the pattern of amino acid mutations and the ratio of synonymous and nonsynonymous substitutions to determine whether it is under different selection pressure in both the compartments. Phylogenetic and mutational analysis of the HIV-1 RT in plasma and genital secretions of HIV-1-infected ART-naive females showed limited variation likely reflecting the absence of differential selection pressure and therefore genetic variation in these compartments.
