SYTO9/PI staining was applied to differentiate cells with intact membranes (green) from those with damaged membranes (red). Salmonella: non-treated S. Typhimurium. MG = 128 μg/mL; Ty = 256 μg/mL; ¼× MT = 32 μg/mL MG and 64 μg/mL Ty; ½× MT = 64 μg/mL MG and 128 μg/mL Ty; and 1× MT = 128 μg/mL MG and 256 μg/mL Ty.
