The Synergy and Mode of Action of Cyperus rotundus L. Extract Plus Ampicillin against Ampicillin-Resistant Staphylococcus aureus

Figure 4

The cell area of ARSA after treatment with CRE and ampicillin either alone or in combination. CON = control (drug-free); AMP (32) = ampicillin at 32 μg/ml; CRE (0.25) = CRE at 0.25 mg/ml; AMP (0.5) + CRE (0.0625) = ampicillin at 0.5 μg/ml plus CRE at 0.0625 mg/ml. The graph shows an area of cell determined by cell width × cell length (nm²). The different superscript alphabets are significantly different from each other. Each treated group was compared using one-way ANOVA and Tukey’s HSD post hoc test; are presented.
