Abstract

The V3 and V4 domains of human immunodeficiency virus type 2 (HIV-2) env genes from 14 rhesus macaques experimentally infected by HIV-2 SBL6669/H5 were sequenced. No variation was observed in viral sequences from sera and from uncultured peripheral blood mononuclear cells during primary infection. The first mutations were detected 17 months after infection; they mainly concerned the region between the V3 and V4 domains and not those domains themselves, which are known to be hypervariable, suggesting that variation of V3 is a late event of HIV infection.
