Evidence of simian immunodeficiency virus (SIV) infection has been reported for 26 different
species of African nonhuman primates. Two of these viruses, SIVcpz from chimpanzees and …

HIV-1 infection is characterized by genetic diversity wherein distinct viral subtypes (clades A,
B, C, D, E, F, G, K and O) are expanding in different geographical regions. This article deals …

The purpose of this study was to document the genetic diversity of human immunodeficiency
virus type 1 (HIV-1) in the Democratic Republic of Congo (DRC; formerly Zaire). A total of …

Nearly 50% of HIV-infected individuals suffer from some form of HIV-associated
neurocognitive disorders (HAND). HIV-1 Tat (a key HIV t rans a ctivator of t ranscription) …

Objective: The objective of this study was to explore whether the differences in rate of spread
of HIV in different regions in sub-Saharan Africa could be explained by differences in sexual …

Genetic diversity is a hallmark of HIV-1 infection with regard to the expansion of distinct viral
subtypes (clades A, B, C, D, E, F, G, K, and O) in different geographical regions. Here, we …

We developed a heteroduplex mobility assay in the gag gene (gag HMA) for the
identification of group M subtypes A to H. The assay covers the region coding for amino acid …

We recently reported a high divergence among African subtype F strains. Three well-
separated groups (F1, F2, and F3) have been shown based on the phylogenetic analysis of …

ABSTRACT A Cameroonian patient with antibodies reacting simultaneously to human
immunodeficiency virus type 1 (HIV-1) group O-and group M-specific V3-loop peptides was …

Here we describe, for the first time, recombinants between two highly divergent major
groups of human immunodeficiency virus type 1 (HIV-1), M and O, within a Cameroonian …
