Genetic characterization of 13 subtype CRF01_AE near full-length genomes in Guangxi, China

AIDS Res Hum Retroviruses. 2010 Jun;26(6):699-704. doi: 10.1089/aid.2010.0026.

Abstract

Guangxi is an important transit area for HIV transmission in South China. Characterization of the full-length genome of HIV-1 prevalent in the area is important for phylogenetic analysis and vaccine development. CRF01_AE is one of the most rapidly spreading subtypes in Guangxi. In this study, we reported thirteen near full-length CRF01_AE genomes from Guangxi, China. The nearly full-length genome was reverse transcripted and amplified in two halves with the 1-kb overlap regions. The PCR products were sequenced directly. The sequence analysis showed that all of 13 strains were CRF01_AE recombinant subtypes. Two clusters were set up with all of the sequences that grouped separately with sequences from Vietnam and Fujian, China, which strongly suggested multiple introductions of CRF01_AE strains into Guangxi province. The results will improve our understanding on the phylogenetic relationship of CRF01_AE strains in South China and also help in the development of a successful HIV vaccine.
