Growth curves and growth kinetics of A. baumannii ATCC 17978 and its isogenic mutant derivative lacking (A) genes involved in the synthesis of the DHBA precursor, (B) genes involved in the synthesis of the N-hydroxyhistamine precursor and (C) genes involved in the modification and assembly of the acinetobactin precursors into the final molecule. The growth curves were performed under iron-limiting conditions. Three independent biological replicates were performed. Unpaired student t test was used for the statistical analysis of the growth kinetics (∗P < 0.05; ∗∗P < 0.01; ∗∗∗P < 0.0001).
