SEQUENCES AND THEIR USE FOR DETECTION AND CHARACTERIZATION OF E. COLI 0157:H7
This invention relates to a rapid method for detection and characterization of Escherichia coli bacteria serotype O157:H7 based on the presence of nucleic acid sequences, in particular, to a PCR-based method for detection, and to oligonucleotide molecules and reagents and kits useful therefore. This method is preferably employed to detect E. coli O157:H7 in a food or water sample, such as a beef enrichment. The present invention further relates to replication compositions and kits for carrying out the method of the present invention.
