Antibacterial efficacy of ethanolic extract of and leaves on methicillin-resistant and shiga-toxigenic .

Objective: This study aims at investigating the antibacterial potential of ethanolic extract of (common name: Green tea) and (common name: Neem) leaves on methicillin-resistant (MRSA) and shiga-toxigenic (STEC).

Materials And Methods: Fresh leaves were processed and extracted by 99% ethanol and reconstituted with 50% ethanol before testing. Disk diffusion and broth microdilution methods were used to determine zone diameter of inhibition (ZDI) and minimum inhibitory concentration (MIC), respectively.
