摘要: 金黄色葡萄球菌(Staphylococcusaureus,S.aureus)是引起食物中毒的主要致病菌之一,其传统方法包括选择性培养、生化鉴定等步骤,耗时长、灵敏性差,很难满足食品安全快速检测要求。PCR技术是近年来广泛应用于食品中致病微生物快速检测的现代方法之一,其目的基因多种多样,主要包括耐药性相关基因、毒素基因、酶基因及多种特异性鉴别基因。本文综述了PCR技术应用于金黄色葡萄球菌检测的各种目的基因,并简要介绍了多重PCR及实时定量PCR等新技术的应用。

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.
