Patent ID: 7838656

Claim:
A probe-immobilized carrier for specifically detecting a gene of infectious disease pathogenic bacterium, Flavobacterium (genus), in a sample potentially containing Escherichia coli , the probe-immobilized carrier having a region where at least two isolated and purified probes selected from the following probes (A) to (C) are immobilized on a solid-phase carrier as arranged at intervals so that the gene of Flavobacterium (genus) capable of reacting with all of the at least two probes can be detected as precisely distinguished from Escherichia coli when the sample is brought into contact with the probe-immobilized carrier under stringent conditions: (A) a probe having the nucleotide sequence of GGAAGTAACTAGAATATGTAGTGTAGCGGTG (SEQ ID NO. 73) or the complementary sequence thereof; (B) a probe having the nucleotide sequence of GCCAGTGCAAACTGTGAGGAAGGT (SEQ ID NO. 74) or the complementary sequence thereof; and (C) a probe having the nucleotide sequence of GGGTAGGGGTCCTGAGAGGGAGATC (SEQ ID NO. 75) or the complementary sequence thereof.
