HIV-1 Molecular Characterization and Transmitted Drug Resistance Prevalence among Treatment-Naïve Individuals
The distribution of different human immunodeficiency virus type 1 (HIV-1) genotypes and the prevalence of transmitted drug resistance (TDR) mutations vary greatly across different Brazilian regions. This study aimed to describe the HIV-1 molecular diversity and TDR prevalence among treatment-naïve HIV-1 infected individuals in an urban area of Northeastern Brazil. DNA samples from 97 infected individuals were obtained and pol sequences were generated by Polimerase Chain Reaction (PCR) and direct sequencing. Bioinformatics tools were used to identify the presence of associated mutations with drug resistance, to reconstruct the phylogeny and to detect recombination.
