The objective of this study was to characterize the molecular profile of HIV-1 epidemic in Salvador, Bahia, Brazil, determining the genetic subtypes and the presence of antiretroviral resistance mutations. HIV-1 pol DNA sequences from 57 individuals infected with HIV were obtained by PCR, followed by sequencing. The subtypes were determined by phylogenetic analyses and the intersubtype recombination was investigated by bootscanning. The pol subtypes were compared with gag and env subtypes. Antiretroviral susceptibility was evaluated through the Stanford HIV resistance Database. The subtypes frequencies were: 77.2% of subtype B, 1.8% of subtype F1, and 21.0% of BF recombinant forms. Two intergenic and three intragenic BF recombinant patterns were observed. Six (10.5%) viruses were related to CRF28/CRF29, two were related to CRF12 (3.5%), and one (1.8%) was CRF39. Fourteen (24.6%) strains carried one or more mutations associated with at least intermediate resistance: 24.6% had resistance to nucleoside reverse transcriptase inhibitors, 21.0% to non-nucleoside reverse transcriptase inhibitors, and 7% to protease inhibitors. The substitutions I54V (7.0%), M184V (14.0%), and K103N (10.5%) were the most frequent within each class of drugs. The results show a high diversity of BF genotypes and a lower prevalence of major reverse transcriptase and protease drug resistance mutations in Salvador, compared with other regions of Brazil. These findings may contribute to improve treatment strategies of patients infected with HIV-1 from this Brazilian region.Submitted by Edileide Reis (leyde-landy@hotmail.com) on 2014-02-18T14:16:33Z No. of bitstreams: 1 Bernardo Galvao Castro.pdf: 175093 bytes, checksum: 7161dacf3400a63091b7578201e1e0d9 (MD5)Approved for entry into archive by Flávia Ferreira (flaviaccf@yahoo.com.br) on 2014-11-28T15:45:58Z (GMT) No. of bitstreams: 1 Bernardo Galvao Castro.pdf: 175093 bytes, checksum: 7161dacf3400a63091b7578201e1e0d9 (MD5)Made available in DSpace on 2014-11-28T15:45:58Z (GMT).
