B, CRF01_AE and CRF07_BC are three major HIV-1 subtypes circulating in China. Here we detected a novel CCR5-tropic HIV-1 recombinant virus (GX2016EU23), which was isolated from an HIV-1-infected man who had sex with men (MSM) in Guangxi, China. Phylogenetic analysis of the near full-length genome showed that GX2016EU23 consisted of at least seven segments, that is two B, two CRF01_AE, and three CRF07_BC segments. Recombinant breakpoints of GX2016EU23 were observed in the gag, pol, rev, and env regions. This is the first detection of a novel HIV-1 recombinant (B/CRF01_AE/CRF07_BC) in MSM in Guangxi. The emergence of this novel recombinant suggests the increasing genetic diversity of the HIV-1 epidemic among the MSM group in China.
B、CRF01_AE和CRF07_BC是在中国流行的三种主要的HIV-1亚型。在此,我们检测到一种新型的CCR5嗜性HIV-1重组病毒(GX2016EU23),它是从中国广西一名与男性发生性行为的HIV-1感染男性(男男性行为者)中分离出来的。对近全长基因组的系统发育分析表明,GX2016EU23至少由七个片段组成,即两个B片段、两个CRF01_AE片段和三个CRF07_BC片段。在gag、pol、rev和env区域观察到GX2016EU23的重组断点。这是在广西男男性行为者中首次检测到新型HIV-1重组体(B/CRF01_AE/CRF07_BC)。这种新型重组体的出现表明中国男男性行为者群体中HIV-1流行的遗传多样性在增加。
