FIG. 5.

Following oral infection, both wild-type and RAG1 KO mice were heavily colonized by C. rodentium. The numbers of bacteria recovered from the colons of individual infected wild-type mice (solid circles) and RAG1 KO mice (open circles) are presented on days 6, 10, 14, 18, 21, and 24 p.i. Each group contained four to five mice. The asterisk denotes the recovery of significantly more bacteria (mean value) recovered from RAG1 KO mice than from wild-type mice at days 18, 21, and 24 p.i. ∗, P < 0.05.
