CiaI is delivered from the C. jejuni F38011 wild-type strain to INT 407 cells. Delivery of the CiaI-ACD, FlaA-ACD, FlaG-ACD, and FlgB-ACD fusion proteins was assayed in the C. jejuni F38011 wild-type strain and isogenic flgE mutant. INT 407 cells were inoculated with the C. jejuni F38011 wild-type strain and flgE mutant harboring the various ACD plasmids. The concentration of cAMP within the INT 407 cells was assayed 30 min post-infection. The error bars represent one standard deviation from mean. The asterisk indicates that the amount of cAMP produced in the wild-type strain was significantly greater than the value obtained from the flgE mutant, as judged by the Student's t-test (P < 0.05).
