Amanda's mother believes that garlic has helped Amanda's grandmother live a long, healthy life. This encouraged Amanda to learn more about garlic's properties, especially its antibiotic properties. Amanda wondered if garlic could help fight the growing problem of antibiotic-resistant microbes.
Raw and cooked garlic was added to tubes filled with fluids representing a digestive mixture: saliva (mouth), hydrochloric acid (stomach), pepsin (stomach), and sodium hydroxide (small intestine). Extracts from the tubes were added to agar plates containing nonresistant E. coli, ampicillin-resistant E. coli, or kanamycin-resistant E. coli. Raw garlic was more effective against the bacterium than cooked garlic, but the presence of each inhibited the spread of all three strains of E. coli.
