Growth of iroN deficient and iroN proficient S. Typhimurium strains in the murine intestine in vivo. (A) Recovery of S. Typhimurium from colon contents 48 hours after infection of mice with the S. Typhimurium wild-type or an iroN mutant. Each circle represent bacterial numbers recovered from an individual animal. Bars indicate the geometric mean. (B) Recovery of S. Typhimurium 48 hours after competitive infection with the indicated bacterial strains. Bars indicate the average competitive index (i.e. ratio of wild-type/iroN or ratio of invA spiB/invA spiB iroN) of bacteria recovered from colon contents of wild-type mice or Lcn2−/− mice 48 hours after infection with a 1:1 mixture the respective S. Typhimurium strains. Data represent geometric means ± standard error.
