Abstract

Continual generation of HIV-1 recombinant forms might contribute to its genetic diversity. In this study, a novel B/C/CRF01_AE recombinant virus (GX2016EU13) was identified, which was isolated from a HIV-positive man who was infected through heterosexual sex in Guangxi, China. GX2016EU13 was identified as CCR5-tropic. As shown in the near full-length genome (NFLG) analyses, five recombinant breakpoints were found only in the pol gene of GX2016EU13, which divided the NFLG into three subtype B segments, two subtype C segments, and one CRF01_AE segment. The whole gag sequence of GX2016EU13 belongs to subtype B, and the whole env sequence of GX2016EU13 belongs to CRF01_AE. The recombinant form was distinct from the other circulating recombinant forms and unique recombinant forms reported. The emergence of GX2016EU13 may suppose the complexity of the HIV-1 epidemic in high-risk sexual populations in Guangxi, China.
