(a) 96-well plate plus sample: control (QXJT) means QXJT was continuously twofold diluted without adding bacteria liquid as control; positive control meant broth is added with bacteria without drugs; negative control meant broth is added without bacteria without drugs. (b) QXJT against MRSA2007118 (broth microdilution method results); MIC = 18.75 mg/ml. (c) QXJT against MRSA2008043 (broth microdilution method results); MIC = 37.5 mg/ml. (d) QXJT against MRSA2007118 (broth macrodilution method results); MIC = 18.75 mg/ml. (e) QXJT against MRSA2008043 (broth macrodilution method results); 37.5 mg/ml.
