Near Full-Length Genome Identification of a Novel HIV Type 1 B′/C Recombinant Isolate JL100091 in Jilin, China

Abstract We report here a novel HIV-1 B′/C recombinant isolate JL100091, identified from an HIV-positive female subject infected through heterosexual transmission in Jilin in 2006. The near full-length genome analyses of the novel recombinant (JL10091) showed that one subtype B′ region (3,085 bp) was inserted into the subtype C backbone, with two breakpoints observed in gag and pol genes. To our knowledge, this is the first detection of a novel HIV-1 B′/C recombinant in Jilin, which indicates ongoing transmission of networks among the heterosexual population in the region. The novel HIV-1 B′/C recombinant (JL10091) in Jilin originated from India subtype C and China subtype B′ may suggest potential transmission routes of HIV-1 in China. Further monitoring of the molecular epidemiology of the HIV-1 epidemic in Jilin will provide critical information for designing effective control and prevention measures against HIV transmission in the region.
