Abstract:  Staphylococcus aureus is one of the most important pathogens in our daily lives. The traditional detection methods which include selective cultures and biochemical assay are often taking a long time with less sensitivity, so it indeed could not meet the demand of modern food safety requirement. The PCR technology has been introduced for the pathogens detection these years and many target genes required including the genes of various toxins,engymes,drug resistance species and some specific species. This article concludes the genes frequently used in the PCR detection and the application of multiplex PCR and real-time PCR technologyu pdated.
