D: diarrhea; C: control; T: total; VF: virulence factor; : number; %: percentage. The presence of significant differences between specific groups. In 1 C. jejuni the cdtABC operon was amplified but no individual gene amplification was obtained; similarly in 11 C. jejuni and 4 C. coli cases the 3 individual genes were amplified, but no amplification for the full cdtABC operon was obtained.
