Core Tip

Core tip: In the present study, we developed an effective real-time polymerase chain reaction method based on the specific DNA sequence of the hipO gene in Campylobacter jejuni (C. jejuni). The detection limit of this assay is 4.3 CFU/mL. A study of 242 clinical stool specimens from diarrheal patients indicated that this method is more sensitive than direct bacterial culture for the identification of C. jejuni from stool specimens.
