Effects of PS-DRz1694 or PS-DRz1366 on the growth of three clinical MRSA isolates in liquid medium (6 mg/l of oxacillin). The growth of different groups was monitored by using OD₆₀₀ measurements. (A) The OD₆₀₀ value of MRSA080302 in different treated groups. (B) The OD₆₀₀ value of MRSA080305 in different treated groups. (C) The OD₆₀₀ value of MRSA080309 in different treated groups. The following are different treated groups: control, 10 mg/l PBS; DRz5491, 10 mg/l DRz5491; DRz1694, 10 mg/l DRz1694; DRz1366, 10 mg/l DRz1366; DRz1694 + DRz1366, 10 mg/l DRz1694 + 10 mg/l DRz1366. The data are shown as mean ± SD for 5 samples
