Abstract

BackgroundSexually transmitted diseases easily spread among sexually active people and often have no symptoms. Rapid and accurate method for detecting these infections are necessary in early stages. The traditional detection methods of them are difficult and timeconsuming. MethodsIn this study, multiplex real time PCR was optimized for rapid identification of Chlamydia trachomatis and Mycoplasma hominis in a single tube and was performed with our designed primers. The sensitivity test was carried out to designed primers with diluted genomic DNA. To defined the specificity, non STD bacteria were used as DNA template. ResultsThis study indicated that the developed multiplex real time PCR can be an effective alternative procedure to the conventional methods for rapid and accurate identification of C Chlamydia trachomatis and Mycoplasma hominis. Multiplex real-time PCR Results of them were checked with melting curves. The sensitivity of our designed primer by multiplex real time PCR for Chlamydia trachomatis and Mycoplasma hominis were 4.78x10(10) and 8.35x10(10), respectively, Which the primers did not amplify any product from a non-STD species. ConclusionsMultiplex real time PCR by our new primers and analysis of melting curves were successfully usable for rapid and accurate detection of Chlamydia trachomatis and Mycoplasma hominis. This assay instead of traditional culture method, has considerable potential to be rapid, accurate and highly sensitive molecular diagnostic tool for simultaneous and direct detection.
