 AB    OBJECTIVE: To analyze the V3 region of HIV-1 gp120 from saliva and to
       consider the diversity of HIV-1 from the other organs. MATERIALS AND
       METHODS: The saliva and blood samples from HIV positive patients were
       collected and HIV DNAs and RNAs were extracted by glass powder. TA
       cloning substances of PCR or RT-PCR products with primers of the V3
       region were sequenced in several clones in each sample. The results were
       compared each other and standard strains. RESULTS: The sequences were
       more likely to those from macrophage-tropic cells (SF-162mc strain) than
       lymphocyte-tropic cells (MN strain). DISCUSSION: Saliva is easy to use
       for clinical diagnosis and for research. The sequence indicates that
       saliva would be meaningful to consider the pathogenesis of HIV
       infection.
