Food-poisoning bacteria detection carrier, and method for detecting food-poisoning bacteria
A plurality of probes are immobilized on a carrier for detecting food poisoning bacteria, the plurality of probes being selected, either alone or in combination, respectively from two or more groups among a first probe group for detecting Escherichia coli , a second probe group for detecting Listeria , a third probe group for detecting Campylobacter , a fourth probe group for detecting Vibrio parahaemolyticus , a fifth probe group for detecting Staphylococcus aureus , a sixth probe group for detecting Salmonella , and a seventh probe group for detecting Bacillus cereus . Two or more types of food poisoning bacteria among Escherichia coli, Listeria, Campylobacter, Vibrio parahaemolyticus, Staphylococcus aureus, Salmonella , and Bacillus cereus can be specifically and simultaneously detected using the carrier.

a plurality of probes immobilized on the microarray, wherein the plurality of probes comprises: a probe from a first probe group, a probe from a second probe group, a probe from a third probe group, a probe from a fourth probe group, a probe from a fifth probe group, a probe from a sixth probe group, and a probe from a seventh probe group, wherein
the probe from the first probe group hybridizes to a nucleic acid fragment of Escherichia coli , and the first probe group consists of probes consisting of SEQ ID NO: 1 to 4 or the complements thereof,
the probe from the second probe group hybridizes to a nucleic acid fragment of Listeria , and the second probe group consists of probes consisting of SEQ ID NO: 7 to 13 or the complements thereof,
the probe from the third probe group hybridizes to a nucleic acid fragment of Campylobacter , and the third probe group consists of probes consisting of SEQ ID NO: 14 to 19 or the complements thereof,
the probe from the fourth probe group hybridizes to a nucleic acid fragment of Vibrio parahaemolyticus , and the fourth probe group consists of probes consisting of SEQ ID NO: 20 to 24 or the complements thereof,
the probe from the fifth probe group hybridizes to a nucleic acid fragment of Staphylococcus aureus , and the fifth probe group consists of probes consisting of SEQ ID NO: 25 to 29 or the complements thereof,
the probe from the sixth probe group hybridizes to a nucleic acid fragment of Salmonella , and the sixth probe group consists of probes consisting of SEQ ID NO: 30 to 40 or the complements thereof, and
the probe from the seventh probe group hybridizes to a nucleic acid fragment of Bacillus cereus , and the seventh probe group consists of probes consisting of SEQ ID NO: 41 to 45 or the complements thereof,
wherein the plurality of probes specifically and simultaneously hybridize to the nucleic acid fragments of Escherichia coli, Listeria, Campylobacter, Vibrio parahaemolyticus, Staphylococcus aureus, Salmonella , and Bacillus cereus.
2. The microarray of claim 1 , wherein the plurality of probes comprises two probes selected respectively from each of all groups.
