Human papillomaviruses and Chlamydia trachomatis are two of the most commonly found sexually transmitted infections in cervical Pap smears. They are often asymptomatic and if left untreated can progress to cause serious complications such as pre-cancerous lesions and tubal factor infertility, respectively. The aim of this study was to develop a rapid multiplex PCR for the simultaneous detection of HPV and C. trachomatis in ThinPrep® liquid cytology samples. Two multiplexes were optimized. (A) For the detection of C. trachomatis using primers for the cryptic plasmid and for a chromosomal gene ( Hsp60 ); (B) for the simultaneous detection of HPV and C. trachomatis using consensus primers for HPV and plasmid primers for C. trachomatis . Both multiplexes included a set of primers for a human housekeeping gene- β -globin. DNA from 34 ThinPrep® cervical samples was extracted using the QiAmp DNA Mini Kit (Qiagen Ltd, UK). All 34 samples were previously confirmed positive for C. trachomatis using another nucleic-acid based test. Using multiplex A.for the detection of C. trachomatis , 33 of 34 samples were positive for C. trachomatis by either the plasmid or chromosomal gene primer set. All samples were positive for β -globin. Ten of the 34 C. trachomatis positive samples were known positives for HPV. Using the combined HPV and C. trachomatis multiplex 10 of 10 were positive for both HPV and C. trachomatis . These simple multiplexes are cost-effective, rapid and have potential for rapid screening of cervical ThinPrep samples simultaneously for both HPV and C. trachomatis . 相似文献
