Variants of human papillomavirus types 53, 58 and 66 identified in Central Brazil.

The present study on molecular characterization of human papillomaviruses occurring in Central Brazil, describes two variants each of HPV-53 and HPV-58 and one variant of HPV-66 detected in samples from smears of women showing cervical intraepithelial neoplasia grade II (CIN II). Samples were assayed by PCR using MY09/ MY11 consensus primers, followed by restriction fragment length polymorphism typing. The five isolates showed atypical restriction fragment length profile and MY09/MY11 L1 PCR products were subsequently sequenced.
