FIG. 7.

(A) Cell counts on day 12 postinfection of C3H mice with wild-type intimin-β-expressing C. rodentium (open bars), intimin-α-expressing DBS255(pCVD438) (hatched bars), and intimin mutant (closed bars) strains. (B) Crypt lengths (day 12) in the colons of wild-type-C. rodentium-infected mice (open bars) or mice infected with C. rodentium expressing human intimin α were significantly greater than those of mice infected with the control mutant strain (closed bars). Each group contained five mice. Values are means ± standard errors. ∗, P < 0.05.
