In 1928, Alexander Fleming noticed a strange mould on a petri dish, and this observation launched the antibiotic era

A chance observation by Alexander Fleming in 1928 led to the discovery of penicillin, the first widely used antibiotic. Initially, its production was challenging, but later scientists like Florey and Chain refined its extraction and purification. This breakthrough revolutionized medicine, transforming bacterial infections from often fatal to treatable, paving the way for a new era of antimicrobial drugs.
