Human papillomavirus (HPV) can be detected by amplification of
viral DNA. A novel PCR primer set generating a short PCR fragment (SPF
PCR) was used for amplification of a fragment of only 65 bp from the L1
region and permitted ultrasensitive detection of a broad spectrum of
HPV genotypes. The intra- and intertypic sequence variations of the
22-bp interprimer region of this amplimer were studied. Among 238 HPV
sequences from GenBank and clinical specimens, HPV genotypes were
correctly identified based on the 22-bp sequence in 232 cases (97.2%).
Genotype-specific probes for HPV genotypes 6, 11, 16, 18, 31, 33 to 35, 39, 40, 42 to 45, 51 to 54, 56, 58, 59, 66, 68, 70, and 74 were
selected, and a reverse hybridization line probe assay (LiPA) (the
INNO-LiPA HPV prototype research assay) was developed. This LiPA
permits the use of amplimers generated by the SPF as well as the MY
09/11 primers. The assay was evaluated with a total of 1,354 clinical
specimens, comprising cervical scrapes (classifications ranging from
normal cytology to severe dyskaryosis) and formalin-fixed,
paraffin-embedded cervical carcinoma samples. LiPA results were highly
concordant with sequence analysis of the SPF amplimer,
genotype-specific PCR, and sequence analysis of amplimers generated by
MY 09/11 primers. The sensitivity of the SPF primers was higher than
that of the GP5+/6+ primers over a broad range
of HPV types, especially when multiple HPV genotypes were present. In
conclusion, the SPF LiPA method allows extremely sensitive detection of
HPV DNA as well as reliable identification of HPV genotypes in both
cervical smears and paraffin-embedded materials.
