AB OBJECTIVE: To isolate the most reproductive HIV-1 strain from Ugandan
HIV-1 infected patients and determine its genotype with the V3 loop
sequence. METHODS: Peripheral blood samples were collected from the
HIV-1 seropositive patients at Mulago hospital in 1991. The patients
were one male and 5 female, and the mean age was 29.7. Viral RNA were
extracted from the serum and reverse trascriptated. The 650 base pairs
of env gene including V3 region was amplified by the nested PCR method.
The PCR product was cloned into plasmid vector and sequenced. RESULTS:
All of the strains obtained from the patients have same amino acid
sequence GPGRAFV at the apex of the V3 loop. They have some mismatches
around the apex region, but they are similar to the American European
type and are different from the old African type already reported.
DISCUSSION AND CONCLUSIONS: We assume these strains may be imported from
the neiboring countries or a result of natural immunological selection.
In order to know the reason of type variation, further investigation
should be needed.
