<i>In vitro</i> competition experiments in <i>K</i>. <i>pneumoniae</i> ATCC 13883 and 10.85 porin mutants.

<p>The relative fitness of porin mutants in comparison with parental strain (ATCC 13883 or 10.85) or between porin mutants was determined by competition experiments in co-cultures and expressed as a percentage of the mutant or wild type cells versus total population at each time point. <i>In vitro</i> growth conditions, MH broth with continuous shaking at 37°C. Violet diamond, ATCC 13883 or 10.85 wild type strains. Orange square, ΔOmpK35. Red square, ΔOmpK36 mutant. Green square, OmpK36GD mutant. Blue circle, ΔOmpK35ΔOmpK36 mutant. Pink circle, ΔOmpK35OmpK36GD mutant.</p>
