Patent ID: 8343723

Claim:
A method for detecting the presence of Campylobacter bacterium in a test sample, which comprises the steps of: (a) conducting a nucleic acid amplification reaction on the test sample using a common primer pair that can amplify genomic DNAs encoding the cytolethal distending toxin of Campylobacter coli, Campylobacter jejuni , and Campylobacter fetus; (b′) conducting a nucleic acid amplification reaction on the test sample or with the genomic DNA amplified in step (a) as a template using a mixture of primer pairs specific to each of genomic DNAs encoding the cytolethal distending toxins of Campylobacter coli, Campylobacter jejuni , and Campylobacter fetus ; and (b) determining the presence of the Campylobacter bacterium based on the presence or molecular weight of an amplified fragment from the genomic DNA encoding the cytolethal distending toxin of the Campylobacter bacterium.
