title: Identification of human immunodeficiency virus type 1 subtypes and their distribution in the Commonwealth of Independent States (Former Soviet Union) by serologic V3 peptide-binding assays and V3 sequence analysis.
abstract: Serologic V3 loop peptide-binding assays have been used to predict divergent human immunodeficiency virus type 1 (HIV-1) strains from the Commonwealth of Independent States (former Soviet Union) that have been subsequently confirmed by sequencing of the V3 region. Initial screening was done by MN V3 peptide binding; 12 parenterally infected HIV-1-positive subjects from Elista and Rostov (group 1) with low-titer MN binding and 6 heterosexually infected HIV-1-positive adults from Byelorussia (group 2) with high-titer MN binding were selected. A consensus sequence from the Elista and Rostov areas was generated; a corresponding 14-mer peptide was synthesized and used in an indirect ELISA to screen sera from 392 individuals from diverse geographic areas. Reactivity to the consensus peptide was 82% in subjects from the homologous areas and 11%-38% in other areas. Antibody binding to a panel of synthetic V3 peptides may be used to predict the presence of diverse strains of HIV-1 within virally heterogenous populations.
