A disk diffusion assay to test the Antibacterial Activity of Egyptian Artemisia, EA and Jericho Artemisia, JA extracts.

Filter paper (Whatman) disks were soaked in A. EA and JA leaves’ water extracts (500mg/ml), B. EA and JA leaves’ methanol extracts (500mg/ ml), C. EA and JA leaves’ Hexane-chloroform extracts (500mg/ml), and in Ampicillin (100 mg/ml) and Kanamycin (25 ug/ ml) as positive controls for 12 hours. In all cases, disks were applied separately, each extract with a positive control, to Escherichia coli agar plates and incubated for 24 hours at 37C°.
