Epidemiologic and Evolutionary Trends of HIV-1 CRF31_BC-Related Strains in Southern Brazil

11 May 2007

Abstract excerpt

BACKGROUND: To evaluate the impact of HIV-1 CRF31_BC in the southern Brazilian HIV epidemic. METHODS: Blood plasma from 284 patients was collected from July 2002 to January 2003 at 2 reference HIV/AIDS centers in southern Brazil. Viral protease and reverse transcriptase (RT) genomic regions were amplified by RT polymerase chain reaction, sequenced, and subtyped. Evolutionary analyses were performed to estimate...
