Inhibitory activity of Ga(NO3)3 on a collection of 57 A. baumannii strains grown in human serum. Strains were grown for 48 h in serum supplemented with increasing Ga(NO3)3 concentrations (0 to 128 μM). Plots show the Ga(NO3)3 concentrations (μM) required to inhibit the growth of each isolate by 50% (IC50) and 90% (IC90) at 48 h. Boxes represent medians and second and third interquartiles; whiskers represent range of 57 strains. For each strain, the mean value of two independent microtiter plate assays was considered.
