In recent years, general primer-mediated PCR assays have been developed to
detect a broad spectrum of human papillomavirus (HPV) genotypes. In this
study, a procedure enabling a simple group-specific differentiation of
high-risk (HPV-16, -18, -31, -33, -35, -39, -45, - 51, -52, -54, -56, and
-58) and low risk (HPV-6, -11, -34, -40, -42, - 43, and 44) HPVs following
an HPV general primer-mediated (GP5+/GP6+) PCR is presented. By
computer-assisted sequence analysis, oligonucleotides (30-mers) specific
for 19 different HPV genotypes were selected from the internal part of the
150-bp GP5+/GP6(+)-amplified region. These oligo probes were tested for
specificity in a Southern blot analysis of PCR products derived from the
same panel of HPV types. No cross-hybridizations were found. The
sensitivities of the oligo probes varied from the femtogram level for the
well-amplified HPV types like HPV-16 and -18 to the picogram level for the
less-well amplified HPV types like HPV-39 and -51. These sensitivities were
reached when the oligo probes were applied both individually and in a
cocktail. On the basis of these results, two cocktail oligo probes that
enabled a specific and sensitive differentiation between low- and high-risk
HPV types were composed.
