Two Australian HIV-1 isolates, derived from patient blood (HIV(MBC200)) and cerebrospinal fluid (HIV(MBC925)), were characterized after in vitro culture in peripheral blood mononuclear cells (PBMC). Although virus replication was similar, as measured by cell-free reverse transcriptase activity, only one of the two isolates (HIV-1(MCB200)) consistently induced cell syncytia and depleted the PBMC population of CD4+ cells by cell killing. A novel technique, devised for rapidly obtaining high-quality viral sequence data and the full-length genomic sequence of these two isolates, is presented. Analysis of the predicted sequence of the viral Env proteins provides correlates of the observed phenoty..View full abstract
