    Abstract:
    Two cocktails of digoxigenin-labeled human papillomavirus (HPV) type-specific oligonucleotide probes and an enzyme immunoassay (EIA) were used as a basis to developed a group-specific detection method for 14 high-risk (types 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68) and 6 low-risk (types 6, 11, 40, 42, 43, and 44) HPVs, following a general primer GP5+/bioGP6(+)-mediated PCR. The sensitivity of this high-risk/low-risk (HR/LR) HPV PCR-EIA ranged from 10 to 200 HPV copies, depending on the HPV type. Comparison of HR/LR HPV PCR-EIA with radioactive Southern blot hybridization using a general probe on the same PCR products derived from 417 cytomorphologically abnormal cervical scrapings resulted in an overall agreement of 96% between the two methods. Complete concordance between group-specific HR/LR detection and individual typing results for both single and multiple infections indicate the strong specificity of this HR/LR HPV PCR-EIA. Multiple infections could be predicted by comparing PCR-EIA optical density values of the cocktail probes with one of the individual oligonucleotide probes. This novel HR/LR PCR-EIA allows accurate and rapid identification of high-risk and low-risk HPV types in cervical scrapings and will facilitate HPV detection in HPV mass-screening programs.
