Aerobactin Synthesis Genes iucA and iucC Contribute to the Pathogenicity of Avian Pathogenic Escherichia coli O2 Strain E058
Figure 2
Growth curves of E058 wild-type strain and its mutants.
(A) The E058(□), E058ΔiutA(▪), E058ΔiucA(▴), E058ΔiucC(×), E058ΔiucAΔiutA (*) and E058ΔiucCΔiutA (•) strains were grown in LB broth at 37°C, respectively, and their growth curves were determined by measuring viable counts (CFU ml−1). (B) Growth curves of the E058 and its mutants in LB containing 200 µM 2,2′-dipyridyl (DIP). The data represent averages of three independent assays.
