Genetic analysis of HIV type 2 in monotypic and dual HIV infections

AIDS Res Hum Retroviruses. 2000 Feb 10;16(3):295-8. doi: 10.1089/088922200309395.

Abstract

A significant level of genetic variation among HIV-1 and HIV-2 has been described. The interaction of specific HIV-2 subtypes with HIV-1 may serve to identify potential biological properties associated with dual infection. To genetically characterize the HIV-2 strains circulating in Senegal and their relationship to coinfection with HIV-1, we sequenced the HIV-2 envelope C2-C3 region of 12 subjects coinfected with HIV-1 and HIV-2 and 9 subjects singly infected with HIV-2. The phylogenetic analysis showed that all subjects were infected with HIV-2 subtype A, confirming its predominance in West Africa. We did not observe specific sequences or genetic clustering based on coinfection status.
