 AB    AIM: To determine the V3 region sequences from HIV-1 isolates from
       heterosexually infected patients from India. METHODOLOGY: PBL samples
       were cocultured with normal PBLs and the DNA was extracted for PCR. The
       1.5 kb gp120 fragment was cloned and the V3 region sequenced. RESULTS:
       All isolates belonged to the C subtype. Most isolates had amino-acid
       residues similar to the V3 loop consensus sequences published in the Los
       Alamos database (Nov '93 III-71). One isolate had a serine in the 6 th
       position of the V3 loop. Another isolate had an arginine in the 1st
       position, alanine in the 20 th position and a phenylalanine in the 22 nd
       position of the V3 loop. These residues have not so far been reported
       for the C subtype in the Los Alamos database. The N-linked glycosylation
       site proximal to the first cysteine residue of the V3 loop was absent in
       all the isolates. CONCLUSION: C subtype of HIV-1 was the strain
       transmitted through the heterosexual route in the HIV-1 isolates
       obtained from India.
