New recombinant variants are a predominant challenge for preventing the spread of the HIV-1 epidemic. In this study, we confirmed a novel HIV-1 CRF07_BC/CRF55_01B recombinant form for the first time, which was isolated from a male patient in Jiangmen, China. The genomic sequence of the variant with four CRF55_01B segments inserted into the CRF07_BC backbone is 8,510 bp in length, extending from nucleotides 669 to 9,293 according to the HXB2 genome. Specifically, the recombinant strain contains site mutations associated with drug resistance.
