  • a Bacterial mixtures were incubated with equal amounts for 24 h with shaking. Cells were then diluted and plated to determine the relative percentage of each strain recovered. CI of wild-type versus Kat, wild-type versus Ahp, and wild-type versus HpxF strains were determined.

  • b A one-sample t test was used to determine whether the CI was significantly different from 1.

  • c NS, not significant.
