Recombination was most important in the generation of new viral strains and in the increase of HIV diversity. There were more and more new HIV-1 strains. Not only circulating recombinant forms (CRFs) but also unique recombinant forms (URFs) have been reported around the world. CRF07_BC and CRF08_BC were the two predominant CRFs circulated in Yunnan Province, southwest China. In the present study, we identified two new HIV Type 1 unique (B/C) recombinant gorms in Yunnan Province by nucleotide sequencing in two halves of HIV genome. Although the genomic structures of the two B/C recombinants were different from previously identified CRFs (CRF07_BC and CRF08_BC) and URFs in Yunnan Pprovince, they have several common recombination sites with CRF07_BC and CRF08_BC.
重组在新病毒株的产生以及HIV多样性的增加中最为重要。出现了越来越多的新型HIV-1毒株。世界各地不仅报道了流行重组型（CRF），还报道了独特重组型（URF）。CRF07_BC和CRF08_BC是在中国西南部云南省流行的两种主要CRF。在本研究中，我们通过对HIV基因组两半部分进行核苷酸测序，在云南省鉴定出两种新的1型HIV独特（B/C）重组型。尽管这两种B/C重组体的基因组结构与云南省先前鉴定的CRF（CRF07_BC和CRF08_BC）和URF不同，但它们与CRF07_BC和CRF08_BC有几个共同的重组位点。
