The Discovery of Penicillin
Penicillin, discovered by Alexander Fleming nearly a century ago, is a revolutionary antibiotic that emerged accidentally. While examining a Petri dish, Fleming found that a mold produced by Penicillium notatum could kill bacteria. This transformative discovery led to penicillin being widely regarded as a revolutionary drug capable of treating infections such as strep throat and meningitis. It is part of a larger family of antibiotics, including amoxicillin and methicillin, which have collectively saved millions of lives and remain among the safest and most effective medications today.
