Primer pairs in the HIV-1 POL and ENV genes were evaluated by performing a PCR on lysed peripheral blood mononuclear cells (PBMCs) from 96 HIV-1 seropositive and 40 seronegative individuals originating from 16 different geographical localities in Africa, Europe and Haiti. A single PCR using primer pairs to the LTR, GAG and ENV regions and detection by radioactively labelled oligonucleotide probes was compared to a nested PCR scheme using newly designed POL and ENV primers which used ethidium-bromide staining of the amplified product on agarose gel. The newly designed POL nested primer pair was shown to be highly sensitive (93%) and specific (100%) for the detection of HIV-1 proviral DNA of very diverse geographical and genetic origin, including highly aberrant HIV-1 isolates. The sensitivity of the newly designed ENV primers was 68.7%, which does not differ significantly from the sensitivity of the classical primers, SK 68/69. Both ENV primers were unable to amplify two SIVcpz isolates from naturally infected chimpanzees.
