A) Intracellular iron levels assessed by Prussian Blue staining in untreated and IFN-γ activated THP-1 macrophages, and (B-D) infected with three siderophilic bacteria (magnification = 100X). Percentage total area of Prussian Blue (PB) pixels in macrophages after infection with (E) L. monocytogenes, (F) M. bovis BCG, or (G) S. enterica with or without IFN-γ treatment. *p<0.05, **p<0.01, ***p<0.0001.
