∗Data are expressed as mean ± SEM. #Data are expressed as mean (Min-Max) of the 20 clinical isolates of MRSA. n denotes the number of MRSA isolates which gave a measurable diameter. Vancomycin was used as the positive control. 10% DMSO was used as the negative control. – denotes a measurable diameter was not observed. |
