Antimicrobial activity of methanol and aqueous extracts of some medicinal plants against Klebsiella pneumonia


The study was conducted to investigate the antimicrobial activity of methanol and aqueous extracts of Melia azedarach L. fruit; M. stem, Lantana camara flower, L. camara fruit, Cordia dichotoma fruit, Ricinus seeds, Pomegranate peel, Senna leaves, using well, and discs agar diffusion methods, in addition to find Minimum Inhibitory Concentration, and Minimum Bactericidal Concentration against Klebsiella pneumonia which was isolated from (Operation rooms in hospitals, Wounds, Cow's milk, Vegetable(Salts). Out of the two crude extracts, the methanol extract showed the highest activity. The well diffusion method was better than disc diffusion method as way to evaluate the sensitivity of microorganisms. Pomegranate peel extracts of both methanol and aqueous extract showed the highest anti- Klebsiella activity. The results justify their use in traditional herbal medicine for the management of bacterial based diseases
