Multiplex real-time SYBR Green I PCR assays for simultaneous detection of 15 common enteric pathogens in stool samples.
2020
Diarrheal diseases account for more than 50% of foodborne diseases worldwide, the majority of which occur in infants and young children. The traditional bacterial detection method is complex and time-consuming; therefore, it is necessary to establish a rapid and convenient detection method that can detect multiple pathogens simultaneously. In this study, we developed a set of five multiplex real-time SYBR Green I PCR assays to simultaneously detect 15 common enteric pathogens based on the Homo-Tag Assisted Non-Dimer system. These assays effectively reduced primer-dimer formation and improved the stability, uniformity, and amplification efficiency of multiplex PCR. The detection limit of the multiplex SYBR Green I PCR system was approximately 104-106 CFU/mL for stool specimens. Furthermore, we vitrified heat-unstable components on the cap of a reaction tube, showing that Taq DNA polymerase, dNTPs, primers, and SYBR Green I remained stable at 25 °C. In summary, we developed multiplex SYBR Green I PCR assays that can simultaneously detect 15 enteric pathogens. This method is comprehensive, rapid, inexpensive, accurate, and simple and displays high specificity.
