Competition assays with LB aerated culturesa
| Strain description | Median CI | No. of samples | P valueb | Fold attenuation |
|---|---|---|---|---|
| Kat− | 1.10 | 3 | NSc | NS |
| Ahp− | 0.86 | 3 | NS | NS |
| HpxF− | 0.69 | 3 | NS | NS |
↵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.
