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

Abstract

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.
