Fig. (1) The diagrams reflect the decrease in the bacterial growth (A: Staphylococcus aureus clinical isolate No. 1, B: Staphylococcus aureus clinical isolate No. 2, C: Staphylococcus aureus ATCC 29247 and D: Methicilline – resistant Staphylococcus aureus) which demonstrated by log10 measured by microdilution assay. The decrease in bacterial growth resulted from red cabbage (RC) methanol crude extract treatment in different concentrations. These four bacteria showed no visible growth around the 6 mm disc impregnated in RC methanol crude extract at 500 mg/ml concentration in the disc diffusion test.
