cadDX protects S. suis against cadmium stress. A–E Growth curves of WT, ΔcadDX, C-cadDX, C-cadD, and C-cadX in THB (Control) or THB supplemented with various concentrations of CdCl₂ (7.5, 15, 20, and 30 µM). F–J Bacterial viability of the WT, ΔcadDX, C-cadDX, C-cadD, and C-cadX strains after 6 h of culture in THB (control) or THB supplemented with various concentrations of CdCl₂ (7.5, 15, 20, and 30 µM).
