Carrier for detecting foodborne-illness-causing bacteria, kit for detecting foodborne-illness-causing bacteria, method for detecting foodborne-illness-causing bacteria, and pcr reaction solution for foodborne-illness-causing bacteria

This invention can, with high specificity, detect the presence or absence of Escherichia coli and Vibrio parahaemolyticus regardless of pathogenicity while simultaneously detecting the presence or absence of pathogenic Escherichia coli and Vibrio parahaemolyticus. This invention also makes it possible to detect Escherichia coli, Salmonella sp., Staphylococcus aureus, and Vibrio parahaemolyticus in a sample simultaneously and with high specificity. Said bacteria are detected by the use of a carrier, for detecting foodborne-illness-causing bacteria, on which the following are immobilized: three or more probes selected from the pyrH, vtx1, and vtx2 genes of Escherichia coli; one or more probes selected from the invA gene of Salmonella sp.; one or more probes selected from the dnaJ gene of Staphylococcus aureus; and four or more probes selected from the toxR, tdh, trh1, and trh2 genes of Vibrio parahaemolyticus.
