Abstract

Eleven human immunodeficiency virus 1 (HIV-1) isolates from Ghanaian acquired immunodeficiency syndrome (AIDS) or AIDS-related complex (ARC) patients obtained by our serosurvey in 1986-1994 were genomically analyzed and phylogenetically compared with other known strains. A phylogenetic tree constructed by analyzing the env region indicated that heterogeneous HIV-1 strains were circulating in Ghana and the majority of them (9 of 11 isolates) belonged to clade (subtype) A which is now furiously epidemic in Africa. Another isolate (1 of 11) belonged to clade D, and the remaining one (1 of 11) belonged to "clade G". This "clade G" virus grouped by the env analysis belonged to clade A by its pol sequence, suggesting an A/G intersubtype recombinant. The characteristic sequences in the V3 tip which have not yet been reported were observed in these Ghanaian isolates, which should be taken into account for future vaccine programs.

<OtherAbstract Type="PIP" Language="eng"><AbstractText>The molecular epidemiology of HIV-1 in Ghana was investigated through genomic and phylogenetic analysis of isolates from 11 AIDS or AIDS-related complex patients obtained in 1986-94. A phylogenetic tree constructed by analyzing the env region indicated that heterogeneous HIV-1 strains are circulating in Ghana. 9 of the isolates belonged to clade A, 1 to subtype D, and 1 to "clade G"--an A/G intersubtype recombinant. The V3 loops of all isolates were composed of 35 amino acid residues--a characteristic not previously described. These molecular data on the genetic variability of the envelope glycoprotein of HIV-1 should be useful for future vaccine studies in West Africa.</AbstractText>
