Figure 2. FeoB limits colonization of the spleen and liver in Sv129S6 (Nramp1^+/+) mice.

Mice were orogastrically inoculated with either the WT or a ΔfeoB mutant strain. Fecal pellets were harvested 1 and 3 days post-infection (A). Tissues were harvested and plated for CFU at 2 weeks post-infection (B). Mean and SEM are shown. p-values were determined as described in the methods. p < 0.05 (*) vs. WT; p < 0.01 (#) vs. WT. Each symbol represents one mouse, n = 5.
