Garlic: The Wonder Drug?

CSEF · 2002 Microbiology

Ashley M. Gilroy · Desert Junior/Senior High School, Edwards

Overview

Objectives/Goals To compare the antibacterial properties of Garlic to the antibiotic Erythromycin against staph aureus bacteria. Methods/Materials Tested varied concentrations of each substance (garlic, erythro) on the bacteria and observed growth in test tubes that were put in an incubator for 24 hours. Swabbed resulting growth on agar plates for better observation. Results Garlic did not prevent the growth of bacteria as well as the erythromycin (which killed it completely). The highest concentration of garlic fared the best, killing about 75 % of the bacteria. Conclusions/Discussion Unless used in large concentrations, garlic is not very effective in killing staphylococcus aureus bacteria.

Summary statement
