The discovery of penicillin by Alexander Fleming in 1928 revolutionized healthcare by introducing the first true antibiotic. This breakthrough led to the mass production of penicillin during World War II, significantly reducing mortality from bacterial infections. Despite its success, the misuse of antibiotics has resulted in the rise of resistant bacteria, posing new challenges for modern medicine. Penicillin's development has also spurred a variety of antibiotics designed to treat specific infections.
