Genotyping human papillomavirus type 16 isolates from persistently infected promiscuous individuals and cervical neoplasia patients

Nucleotide sequence variation in the noncoding region of the genome of human papillomavirus type 16 (HPV16) was determined by direct sequencing and single-strand conformation polymorphism analysis of DNA fragments amplified by PCR. Individuals of diverse sexual promiscuity and/or cervicopathology were studied. In a group of 14 healthy, monogamous HPV16-positive females, only two HPV16 sequence variants could be documented. Among 17 females and 3 males with multiple sex partners and living in the same geographical region, nine sequence variants were found, whereas among 7 patients with cervical... Mehr ...
