IL-15−/− mice are more susceptible to Salmonella infection. (A) Survival plots of wild-type mice (B6) and IL-15 knockout mice (IL-15−/−) (n = 8 per group) infected with serovar Typhimurium by the oral route (for mean survival time for IL-15−/− mice versus that for B6 mice, P = 0.0084. (B) Bacterial loads in the spleen and liver of B6 mice and IL-15−/− mice (n = 8 per group). Data are the means with standard errors from two separate experiments (B6 versus IL-15−/− mice: spleen, P = 0.031; liver, P = 0.029.
