| Abstract | ||
| Disc diffusion method , Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) were used to determine the antibacterial activity of methanolic extract of Ginger (Zingiber officinale) against: Escherichia coli ,Pseudomonas spp. ,Salmonella typhi and Staphylococcus aureus .The results showed an inhibitory effect of the methanolic extract on both the growth of the tested bacteria . E.coli was more sensitive to the methanolic extract ,since the averageof diameter of inhibition zones were (19.33,20.67,21.67) mm to the concentrations of (200,300,400) mg/ml respectively while S.aureus was more resistant to methanolic extract ,since the average diameter of inhibition zones were (10.33,12,12.67)mm to the concentrations of (200,300,400)mg/ml respectively. The (MIC)of E.coli, S.typhi ,Pseudomonas spp. and S.aureus were : (0.6,1.25,2.5,5) µg/ml respectively and the (MBC) to the bacteria mentioned above were (1.25,2.5,5,10) µg/ml respectively. | ||
