Figure 1. Colonization and gut-induced leakiness in C. rodentium-infected mice after treatment with B. subtilis.
Mucosal (A) and lumenal (B) colonization of C. rodentium 11 dpi. FITC-dextran in serum of mice 11 dpi with lux+ C. rodentium (C). Cr, C. rodentium-infected mice; Cr + Bs, mice treated with B. subtilis 24 hr prior to C. rodentium; PBS, phosphate-buffered saline. The results are averages from 2 independent experiments and a total of 5–6 mice were assessed for each group. No statistical difference was found between C. rodentium-infected mice and those that received B. subtilis prior to infection.
