Survival curve (a) and bacterial colonization in challenged mice. Bacterial colonization in the liver (b), spleen (c) and cecum (d) of challenged mice (Table 2, group A, immunized with C50336ΔsptP and then challenged with 1 × 108 CFU of C50336; group B, immunized with PBS and then challenged with 5 × 105 CFU of C50336). All samples from the blank control group were negative for Salmonella (Table 2, group C). The number of bacteria was determined and expressed as log10 CFU/g. Data are expressed as the mean ± SEM, **P ≤ 0.01
