摘要：Staphylococcus aureus is a kind of worldwide food-borne pathogen. Recently, S. aureus has gained considerable attention because of the increasing alimentary toxicosis incidence. In this study, a Real-Time fluorescence Loop-Mediated isothermal Amplification (RT-LAMP) was developed to detect S. aureus rapidly. The heat-stable nuclease (nuc) gene of S. aureus , the target sequence, was selected to design four special primers. A rapid detection method for S. aureus was initially established under optimum reaction conditions. The assay, performed for 40 min at 61°C, did not show cross reactivity with other bacterial species. The specificity and sensitivity of RT-LAMP for detecting S. aureus were 100% and 8.0 CFU/mL, respectively. Results indicated that RT-LAMP was a potential field-usable molecular tool for detecting S. aureus . This method can be an alternative to conventional LAMP in clinical applications and operational programs.
