Relative in vivo fitness of a B. pertussis enterobactin receptor mutant during primary infection in mice. Mice were infected intranasally with a 1:1 mixture of wild-type strain UT25Sm1 and enterobactin receptor mutant strain PM19. (A) Total CFU over the course of the infection experiment. (B) Competitive index values were calculated as the mutant/wild-type CFU ratio in the output recovered at each time point divided by the mutant/wild-type CFU ratio in the input inoculum. CI values are shown relative to the reference CI of 1.00 (dashed line). Bars represent mean values, and each symbol represents the total CFU or CI value determined for an individual mouse. An asterisk indicates that the mean CI differed significantly from the mean at the preceding time point.
