Growth kinetics of S. enterica strains in iron available in vitro growth media. Wild type (SE163A), recipient (SE819), and transconjugant (SE819::IncFIB) strains were grown in: LB; LB amended with ferric chloride (iron-rich); and LB amended with 2,2^/ bipyridyl (iron-depleted). Each data point represents the average OD of three replicates. Three independent experiments were performed to examine growth kinetics of the strains. Results of a representative experiment are shown in the graph. ID = iron-depleted and IR = iron-rich
