Fig. 4From: Antibacterial activities, proposed mode of action and cytotoxicity of leaf extracts from Triumfetta welwitschii against Pseudomonas aeruginosaFluorescence of propidium iodide bound to nucleic acids of P. aeruginosa cells after exposure to the acetone, ethanol and DCM/methanol leaf extracts from Triumfetta welwitschii. Cells with no extract were used as the control. Values are for mean ± standard deviation (error bar) for n = 3. The asterisks indicate a significant difference from the control with ***p < 0.001Back to article page
