ABSTRACT

Objective To sequence and analyze the near full-length genome of an HIV-1 subtype G strain identified in Guangxi,China.Methods The demographic information of an individual infected with HIV-1 subtype G strain was investigated,whose peripherial blood was collected.Viral RNA in plasma was extracted.The near full-length genome of HIV was amplified in two halves using RT-nested-PCR.The PCR products were purified and sequenced.Phylogenetic analysis was made using MEGA6 software.Results A near full-length genome of 8847 bp was obtained.In the neighbor-joining tree,the strain clustered with subtype G references,as supported by the high Bootstrap value (100%).The closest phylogenetic relationship was found between our strain and another subtype G strain (JN106043)previously identified in Guangxi,which was supported by the genetic distance (5%)and high Bootstrap value (100%).Conclusion The strain identified in the study might have originated from subtype G strains in Guangxi,suggesting that subtype G has spread locally in Guangxi.Further surveillance of subtype G epidemic in Guangxi is necessary.The near full-length subtype G strain genome will provide information for the surveillance of HIV in Guangxi.
