*a**C. rodentium*infection resulted in a time-dependent increase in the number of TUNEL-positively staining cells at the base of colonic crypts in susceptible mice only. Values represent the mean number of TUNEL-positive cells per 10 colonic crypts ± 1 SEM from three independent experiments, each with groups of four to five mice.↵

*b*Significantly elevated over values from uninfected mice of the same strain (*P*< 0.05).↵

*c*Significantly lower value than that for C3H/HeJ mice at the same time point (*P*< 0.05).
