Figure 1From: Synergistic activity and mechanism of action of Stephania suberosa Forman extract and ampicillin combination against ampicillin-resistant Staphylococcus aureusTime killing-curve of ARSA after exposure to SSE, ampicillin either alone or in combination. Con = control (drug free); SSE (2) = SSE at 2 mg/ml; Amp(256) = ampicillin at 256 μg/ml; SSE(2) + Amp(0.15) = SSE at 2 mg/ml plus ampicillin at 0.15 μg/ml; the values plotted are the means of 4 observations, and the vertical bars indicate the standard errors of the means.Back to article page
