Antimicrobial Activity of Some Medicinal Plants against Pathogenic Microorganisms.

Abstract

The present research work carries out the screening of some medicinal plants and evaluates the antimicrobial activity of plant extract against the pathogenic microorganisms by using the agar well diffusion assay method. Working concentrations (20mg/mL) of the Microbial extracts. Standardized broth cultures of test bacterial isolates (Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella spp, and Enterococci spp) were spread aseptically onto the surface of Mueller-Hinton Agar (MHA) plates, respectively, using sterile cotton swabs. All plant crude extracts showed significant activity against organisms. Zone of inhibition of the extract compared with the standard antibiotics Gentamycin.
