Figure 1From: An iron-acquisition-deficient mutant of Corynebacterium pseudotuberculosis efficiently protects mice against challengePercentage of immunized animals protected from the experimental challenge with C. pseudotuberculosis. Twenty-one days after immunization with recombinant strains of C. pseudotuberculosis, the animals were challenged with 106 C.F.U. of the MIC-6 virulent wild-type strain. Protection was defined as the survival of the immunized mice for four weeks after the challenge. Bars marked with (a) and (b) correspond to the mutants tested three times and five times, respectively. *p < 0.05, **p < 0.01, ***p < 0.001 versus control (ANOVA, post-test Bonferroni).Back to article page
