Fig 1. An frvA mutant is sensitive to iron intoxication in Listeria monocytogenes.

Fig 1

Representative photographs of a disk diffusion assay with wild-type EGDe (WT), an isogenic frvA null mutant (ΔfrvA), and an frvA complemented strain (ΔfrvA pPL2 frvA) on BHI plates with 10 μl of 1 M FeSO4 added onto the filter paper disk. Black lines indicate the clearance zone and red dashed lines indicate the sensitivity zone. ΔfrvA null mutant has a bigger clearance zone (2 ± 0.3 mm difference) and a large sensitivity zone with reduced cell density (28 ± 1 mm).
