Objective To establish a method for detection of four species of food-borne pathogens synchronously by multiplex PCR. Methods Four pairs of suitable primers were designed according to the specific gene fimA of Salmonella spp, gene ldh of Citrobacter freundii , gene idsC of Proteus mirabilis, gene fimA of Edwardsiella tarda. The reaction conditions of multiplex PCR were optimized as well. Results The detec-tion for real samples proved that the multiplex PCR method had the advantages of reliability, sensitivity and rapidness. Conclusion This method can provide a key technical support for developing a kit that detects the four species of food-borne pathogens rapidly.
