Competitive index in mice between WT and mutants of the inducible amino acid decarboxylases.

<p>Mice were orally inoculated with an equal mix of wild-type and mutant strains, spleens were analyzed 5 days post-inoculation. The CI was calculated as the output ratio of mutant to wild-type bacteria divided by the input ratio. Open symbols illustrate individual CI values, horizontal bars indicate means of CI values and error bars represent the standard error of the mean. Abbreviation ns means not significantly different from wild-type, which occurs when p-value (p) is superior to 0.05. The Δ<i>adiA</i>Δ<i>cadA</i>Δ<i>speF</i> strain is the kanamycin resistant version of Δ<i>adiA</i>Δ<i>cadA</i>Δ<i>speF</i> (strain n° 199).
