ABSTRACT
Objective To study the HIV-1 drug resistance (DR) situation among newly infected persons in Dehong.Methods 1048 HIV-1 positive blood samples from July to December in 2006 from Dehong prefecture of Yunnan,were collected.HIV drug resistance were tested using TruGene in newly infected people that were distinguished with BED-CEIA,while the subtype were determined with phylogenetic analysis using a set of reference sequences available on the Los Alamos Database.Results Of sixty-four successfully analyzed samples,drug resistance mutations were detected in 4 samples with the resistance rate as 6.25%.Minor mutation in PR region such as M36I/V,L63P and H69K appeared frequently and the rates were 81.25%,70.31%and 65.63%respectively.The predominantly prevalent strains were seen as C/CRF07_BC/08_BC(65.63%,42/64) in this study.Conclusion The prevalence of genotypic drug resistances in HIV-1 recent infections in Dehong prefecture appeared to be at moderate level.Drug-resistance surveillance program among HIV-1 infections should be continued and strengthened.
