Graphical representation of COI analysis of strains carrying a mutation in prgH. (A) Analysis of phoP ssaV prgH triple mutant strain (HH195) in mixed infection with either phoP or ssaV single mutant strains (HH114 and HH109, respectively). (B) CI corresponding to prgH single mutant strain (HH124) and COIs corresponding to ssaV prgH (HH193) and phoP prgH (HH194) double mutant strains, in mixed infections with either the ssaV or phoP single mutant strain, respectively (HH110 and HH114). The indices represented are CI (white bars) and COI (black bars). The strains used in each mixed infection are represented by the relevant mutation for simplicity and are indicated under the corresponding bar. COIs were compared to 1.0 (indicated by a horizontal dotted line) and to the value of the CI relevant in each case. (A) COIs are not significantly different from the corresponding CIs (P ≤ 0.05). (B) COIs are not significantly different from 1.0 (P ≥ 0.05). wt, wild type.
