In this study, a rapid real-time PCR assay to detect HIV-1 proviral DNA in whole blood was developed using a novel double-stranded primer that does not require a target-specific fluorescent probe or intercalating dye systems. Co-amplification of a human gene RNase P served as the internal control to monitor the efficiency of the DNA extraction and PCR amplification. The HIV-1 amplification efficiency was 100% and could amplify 1 copy of HIV-1 DNA 64% of the time and all attempts to amplify 4 copies were successful in less than 51 min. All 22 HIV-1 sero-positive and 20 sero-negative whole blood specimens tested were classified correctly by this assay. In addition, 22 cultured PBMC specimens infected with various HIV-1 subtypes or CRF (A=2, AC=1, B=4, C=3, D=3, AE=2, F=1, BF=2, G=4) were amplified equally well with a similar threshold cycle (C(t)) number (22.9+/-1.2). The high amplification efficiency and short PCR cycles were in part due to the short target sequence amplified by eliminating the probe-binding sequence between the primers. This assay may be useful as an alternative confirmation test in a variety of HIV testing venues.
