Mark A. Jensen - West Chester PA, US

International Classification:

C12Q 1/68

US Classification:

536 2432

Abstract:

This invention relates to a rapid method for detection and characterization of STEC bacteria 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 STEC bacteria in a food or water sample, such as a beef enrichment. The present invention further relates to isolated polynucleotides, replication compositions, kits, and reagent tablets for carrying out the method of the present invention.
