Human papillomavirus (HPV) is an etiologic agent of cervical cancer and is
the most common sexually transmitted disease in women. PCR amplification of
HPV genomes is the most sensitive method for the detection of
cervicovaginal HPV. We have compared the two most commonly used PCR primer
sets, MY09/MY11 (MY-PCR) and GP5+/GP6+ (GP+-PCR), for the detection of HPV
DNA in cervicovaginal lavage samples from 208 women. Oligonucleotide probes
for 39 different HPV types were used. Both primer sets amplified a wide
spectrum of HPV genotypes and detected similar overall prevalences of 45%
(94 of 208) and 43% (89 of 208), respectively. The MY-PCR system detected
27 of 30 (90%) samples with multiple HPV types, whereas the GP+-PCR system
detected 14 of 30 (47%) samples with multiple HPV types. Differences in the
detection of HPV types 35, 53, and 61 were noted between the two primer
systems. Serial dilution of plasmid templates indicated a 3-log decrease in
the amplification of HPV type 35 by MY-PCR and HPV types 53 and 61 by GP+-
PCR. These results indicate that although the MY-PCR and GP+-PCR identified
nearly equivalent prevalences of HPV in a set of clinical samples,
differences in the detection of specific types and infections with multiple
types were found. Differences in the sensitivities and characteristics of
the PCR systems for the detection of HPV within clinical samples should be
considered when comparing data between studies and/or in designing new
studies or clinical trials.
