Analyses of bacterial growth in increasing concentrations of bovine or human lactoferrin. Bacterial growth was assessed at 24 hours post-inoculation by spectrophotometric measurement of optical density at 600 nm (OD₆₀₀). Cultures were grown in increasing concentrations of human (A, C, G, E) or bovine lactoferrin (B, D, F, H). A. baumannii strains tested were isolated from wounds (A-B), sputum (C-D), blood (E-F), or urinary tract or abdominal cavity infections (G-H). Significant inhibition of bacterial growth compared to medium alone negative control was determined by one-way ANOVA with Tukey’s post-hoc test, *P<0.05, **P<0.01, ***P<0.001, ****P<0.0001, n=3.
