Abstract
We report here a novel HIV-1 recombinant form (18GXD4705) composed of CRF01_AE and subtype B, acquired from an unmarried HIV-positive young man subject infected through homosexual contact in Guangxi Province of eastern China. The phylogenetic analysis of the near full-length genome of 18GXD4705 indicated that one subtype B segment was inserted into the CRF01_AE backbone, with one recombinant breakpoint demonstrated in the pol region. The CRF01_AE region (I and III) of recombinant correlated with a previously reported subcluster 4 lineage. The B subregions (II) are greatly clustered together, with B strain references. The continued generation of this novel recombinant increases the genetic complexity and diversity of the HIV epidemic in Guangxi. In addition, further molecular epidemiological investigations should be conducted to continuously monitor the dynamic transmission of HIV-1 in the region.
