title: Sequence variability of simian immunodeficiency virus in a persistently infected rhesus monkey.
abstract: A juvenile rhesus monkey that was inoculated intravenously with molecularly cloned SIVmac239 became persistently infected. A modified polymerase chain reaction (PCR) procedure was used to specifically amplify full-length envelope (env) gene sequences from DNA extracted from peripheral blood mononuclear cells (PBMC), lymph node tissue, and cells infected with recovered virus at 69 and 93 weeks post-infection. Extensive sequence variability accumulated in vivo in spite of infection with molecularly cloned virus. In the central portion of env. sequence variability was largely confined to three discrete regions.
