Detection and Typing of Human Papilloma Virus by Multiplex PCR with Type-Specific Primers

The primary underlying cause of cervical cancer is infection with one or more high-risk (HR) types of the human papilloma virus (HPV). Detection and typing of HPV have been commonly carried out by PCR-based assays, where HPV detection and typing are two separate procedures. Here, we present a multiplex PCR-based HPV typing assay that detects 20 HPV types (15 HR, 3 probably HR and 2 low risk) using type-specific primers and agarose gel electrophoresis. 46 cervical, urethral, and biopsy samples were analyzed by both Multiplex PCR and PGMY09/11 consensus PCR, and results were compared. 611 samples were further analyzed by Multiplex PCR, 282 were positive for HR HPV, and 101 showed multiple HR HPV infections. The relatively ease and economic accessibility of the method and its improved ability to detect high-risk HPV types in multiple HPV-infected samples make it an attractive option for HPV testing.
