Bacterial colonization in mouse organs. Groups of mice (3 mice/group) were orally inoculated with approximately 1 × 109 CFU of the indicated strains. The bacterial loadings (log CFU/g) in the tissue were determined on days 3, 6, 9, and 12 post-inoculation in the liver (a), spleen (b), and PP (c). The horizontal lines represent the means, and the error bars represent the standard errors of the means. All the mice in wild-type χ3761 group died at 9 days after oral inoculation
