Patent ID: 7588933

Claim:
An isolated nucleic acid consisting of a nucleic acid sequence wherein the nucleic acid sequence is SEQ ID NO. 2, its complementary sequence, a fragment of SEQ ID NO: 2 or a sequence derived from SEQ ID NO: 2 by deletion and/or substitution of one or more bases, said derived sequence hybridizing with sequence SEQ ID NO: 2 or its complementary sequence by contacting with a hybridization solution of 5-fold concentrated sodium saline phosphate EDTA, 0.5% Tween 20, and 0.01% merthiolate followed by washing with a solution containing 10 mM Tris-HCl, 300 mM NaCl and 0.1% Tween 20, pH 7.4, wherein each of said fragment and said derived sequence comprises a nucleotide chain of 30 consecutive nucleotides of SEQ ID NO: 2, excluding a nucleotide chain of 30 nucleotides within or overlapping the region defined by nucleotides 237-570 of SEQ ID NO: 2, and detects enterohemorrhagic Escherichia coli (EHECs).
