Effect of Aqueous and Alcoholic Extract of Hydrastiscanadensis Plant on Bacteria Isolated from Otitis Media

The results of the current study showed that effect alcoholic extract theHydrastiscanadensisplant was more effective than aqueous on bacteria isolated from otitis media at sameconcentrations.As had highest proteusmirabilis,Staphylococcusaerues,Staphylococcus epidermidis,Escherichia coli, Pseudomonas aeruginosa and Klepsiella pneumoniawith aninhibition diameter ranging (20, 18, 17, 16 ,16, 15) mm respectively a concentration 200 mg/ml,The also higher extract, greater inhibitory activityagainst bacterial species,with significant differences in probability level 0.05 two extractson species, exceptPseudomonas aeruginosa, Staphylococcusaerues there no significantdifference effect.
