Abstract

The spread of the HIV-1 circular recombinant CRF02-AG in countries of the former Soviet Union (Commonwealth of Independent States, CIS ) was studied using partial and full-genome sequences. The full-genome sequence of the CRF02-AG recombinant circulating in Russia was obtained for the first time. A global phylogenetic tree of CRF02-AG full-genome sequences was constructed. Three distinct groups of the sequences were detected as clustered by the geographical location (CIS, South Korea, and France), which is indicative of the single-virus introduction in each of the regions mentioned above. The CIS cluster exhibiting minimum genetic diversity was, therefore, relatively young. The phylogenetic analysis of the env gene sequences within the CIS cluster made it possible to clearly discriminate three branches: two of Russian and one of Uzbek origin. The low genetic diversity within the two Russian subclusters provides evidence of at least two recent independent introductions of the CRF02-AG recombinant from Central Asia into Russia.
