Growth inhibition effects of Um-Ma-Luk-Ka-Wa-Tee ethanol extract on methicillin-resistant Staphylococcus aureus NPRC R003 (A), S. epidermidis ATCC 35984 (B), coagulase-positive staphylococci NPRC 308 (C), multidrug-resistant Acinetobacter baumannii NPRC AB034 (D), multidrug-resistant Escherichia coli 2746-08 (E), and multidrug-resistant Pseudomonas aeruginosa 5351 (F). For all graphs, continuous lines represent time points for test (with different concentrations of the extract) cultures and dashed lines represent control (with 1.25% dimethylsulfoxide) cultures. Each symbol indicates the mean±standard deviation for three independent experiments performed in duplicate. OD, optical density.
