Abstract

Introduction: Infection with HPV is the main cause of cervical cancer. Determining HPV infection and the types of HPV plays an important role in diagnosis, treatment and prognosis of cervicitis/cervical cancer. Aims: Determining proportion of high-risk HPV types and the occurrence of coinfection with multiple HPV types. Methods: 177 women with cervicitis or abnormal Pap smear result were enrolled in the study. Performing the real-time PCR for detecting HPV and the reverse DOT-BLOT assay for determining type of HPV in cases of positive PCR. Results: 7 types of high-risk HPV was dectected, the majority of these types were HPV type 18 (74.6%) and HPV type 16 (37.6%); the proportion of infection with only one type of HPV was 30.4% and coinfection with multiple HPV types was higher (69.6%), the coinfected cases with 2 and 3 types were dominated (32.2% and 20.3%, respectively) and the coinfected cases with 4 and 5 types were rare. Conclusion: Use of the real-time PCR and reverse DOT-BLOT assay can determine the high-risk HPV types and the occurrence of coinfection with multiple HPV types. Key words: HPV type, Reverse DOT-BLOT, real-time PCR,PCR, cervical cancer
