Abstract

An interventional study was performed to determine and compare the MICs of aqueous garlic extract (AGE) and Imipenem against standard strains of Staphylococcus aureus ATCC 25923 & Eschericha coli ATCC 25922. The study was conducted in Department of Pharmacology and Therapeutics in collaboration with Department of Microbiology, Mymensingh Medical College, Mymensingh, Bangladesh from July 2014 to January 2015. The MIC of AGE and antibiotic Imipenem were determined with the help of broth dilution method. The MIC of AGE was determined as 400μg/ml and 700μg/ml against Staphylococcus aureus, and Escherichia coli respectively and the MIC of Imipenem was 1μg/ml against Staphylococus aureus and 1.5μg/ml against Escherichia coli. The MICs of Imipenem was much lower in comparison to MICs of AGE for the test organisms. The subculture study showed the same results with that of the primary isolates. From the study it was clearly observed that AGE have anti bacterial effect but is not potent like antibiotic Imipenem. In this regard active ingredient present in garlic needs to be separated & purified for further study.
