Multiple types of human papillomavirus in cervical samples in women in Campo Grande, MS, Brazil

We analyzed 87 cervical samples from Campo Grande, Mato Grosso do Sul, with a PGMY/GP+ nested PCR system. Positive samples were typed using E7 type-specific primer pairs for HPV 6/11, 16, 18, 45 and 66. Eighteen samples (22 percent) were infected with HPV6/11, 18 samples (22 percent) with HPV66, 13 samples (15.9 percent) with HPV45, 8 samples (9.8 percent) with HPV18 and 7 samples (8.5 percent) with HPV16. Seventeen samples (20.7 percent) were infected by two HPV types, and five samples (6.1 percent) by three HPV types. We conclude that infection with multiple types is present at a high frequency in our population and that there is a relation between some types and cytological finds.
