Abstract:
Human papillomaviruses (HPVs) are etiological agents of cervical cancer. In order to assess the epidemiological incidence and frequency of different HPV types, we applied a polymerase chain reaction (PCR)-direct sequencing approach based on the use of MY09/MY11 primers as compared to Hybrid Capture assay. Cervical samples were taken from 1,500 women, both with normal and abnormal cytological smears, and we found an incidence of 6.6% of HPV infection in Brescia. Overall, 97 samples tested HPV-positive, yielding 18 HPV types. The four most frequent HPV types were: HPV 16, -31, -6, and -58. This approach could be used in ordinary laboratory settings for quick and reliable typing of known and novel HPVs from clinical specimens and it could also be applied to anti-cancer vaccine development.
