Protection of Swiss-Webster mice following infection with mutant strains of S. Typhimurium and challenge with WT S. Typhimurium. a) mice were injected with 1 × 104 cfu of various mutant strains of S. Typhimurium and, after 30 days, rechallenged with 1 × 105 cfu of WT S. Typhimurium; b) mice were injected with 1 × 106 cfu of lppB/msbB or lppAB/msbB mutant S. Typhimurium and, after 30 days, rechallenged with 1 × 106 or 1 × 107 cfu of WT S. Typhimurium. The control groups of mice were given a primary challenge dose of 1 × 107 cfu of WT S. Typhimurium. The actual p-values (Fisher’s exact test) are provided. The p-values shown for the WT or the mutant(s) S. Typhimurium were in comparison to those mutants that showed 100% protection. Asterisks denote statistically significant differences.
