核酸检测及相关技术在食源性致病菌快速检测中的研究

Studies on rapid detection of food-borne pathogenic bacteria by nucleic acid testing and related technology

传统的细菌分离、培养与鉴定由于需时较长,难以适应食源性疾病预防控制的需要。近年来,伴随着核酸检测技术的迅猛发展,各种能够快速检测食源性致病菌的方法相继诞生。本文就聚合酶链式反应及其衍生技术、核酸恒温扩增技术、寡核苷酸微阵列技术、免疫磁性细胞分离技术及DNA生物传感器技术在沙门菌、金黄色葡萄球菌、肠出血性大肠埃希菌等食源性致病菌快速检测中的应用研究进行综述。

The traditional methods of bacteria isolation, cultivation and identification are time-consuming, which can＇ t meet the needs of the control and prevention of food-borne diseases. Recently, various kinds of rapid methods for food- borne pathogenic bacteria detection have emerged with the prompt development of nucleic acid testing technology. The application studies on polymerase chain reaction and the techniques derived from it, nucleic acid isothermal amplification, oligonucleotide microarray, immunomagnetic separation and DNA biosensing on food-borne pathogenic bacteria including Salmonella, Staphylococcus aureus and Enterohemorrhagic Escherchia coli, etc. were reviewed.
