Abstract: Garlic is from major herbal. Performed studies on various bacteria have shown bactericidal potency of garlic. In this study, inhibitory effects of garlic extract on common bacteria have tested. Minimal Inhibitory Concentration (MIC) was 156 �g mL 1 for six of eight Staphylococcus aurous and it was 132 �g mL 1for other two. MIC varies from 78 to 624 for Enterobacteriacea. Inhibitory effect of garlic extract for Pseudomonas aeroginosa was lower in comparison with other gram-negative bacteria. This study shows that garlic extract has antimicrobial effect against tested bacteria including Gram-positive Cocci and Gram-negative bacilli.
