antibiotics discovery

Antibiotics are medicines that fight infections caused by bacteria. The discovery of antibiotics began in 1928 when Alexander Fleming noticed that a mold called Penicillium notatum killed bacteria. This led to the development of penicillin, the first true antibiotic. Further research revealed other antibiotics from various sources, including molds, bacteria, and plants. These medications revolutionized medicine, allowing doctors to effectively treat bacterial infections and save countless lives. Today, antibiotics are essential tools in healthcare, although their overuse has led to antibiotic resistance, making some infections harder to treat. Ongoing research aims to discover new and effective antibiotics.
