Abstract
Recombinant forms contribute substantially to the genetic diversity of HIV-1. Recent studies have also revealed that three major viral strains (CRF07_BC, CRF01_AE, and subtype B) have been cocirculating among men who have sex with men (MSM) in Anhui, suggesting a high probability of generating new recombinants. In this study, we reported a novel CRF01_AE and CRF07_BC HIV-1 recombinant form in MSM in Fuyang city of China. Two near full-length genome (NFLG) named FY184 and FY208 were successfully obtained. The genomic composition analysis of the NFLG reveals that it was divided into four segments by three breakpoints, with two regions of CRF07_BC inserted into a CRF01_AE backbone's gag and pol regions. The CRF01_AE regions were originated from a subcluster lineage of CRF01_AE, which is mainly circulating among MSM in China. The emergence of a novel recombinant of CRF01_AE/CRF07_BC is indicative of the increasing genetic diversity of the HIV epidemic in MSM in Anhui.
