Antibacterial activity evaluation of Allium sativum L. (garlic) extracts on Helicobacter pylori

Abstract

In this study, the antimicrobial effect of aqueous, alcoholic extract, fresh juice and powder solution were assayed against six isolates of Helicobacter pylori. All the extracts gave activity against the tested isolates under concentration 400 mg/ml. An aqueous extract gave activity higher than alcoholic extract while the fresh juice gave the highest effect on the tested isolates.The MIC value was determinate by the range from (150 - 350 ) mg/ml. Also the sensitivity was tested toward a number of common antibiotics, the results showed that the garlic extracts have activity near to antibiotics.
