Which discovery inaugurated the antibiotic era?

The turning point tested here is recognizing the discovery that launched antibiotic therapy: penicillin, the first true antibiotic. In 1928, Alexander Fleming observed that a mold contaminant in a Staphylococcus culture had inhibited nearby bacterial growth. He identified the mold’s product as penicillin, a substance capable of killing or inhibiting many bacteria. This showed that microbes could produce medicines that treat bacterial infections, revolutionizing medicine and public health. The full impact came when Florey, Chain, and colleagues later purified penicillin and developed methods to mass-produce it in the 1940s, bringing it into widespread clinical use. While Pasteur, Jenner, and Koch made foundational contributions to microbiology, vaccines, and our understanding of disease, they did not inaugurate the antibiotic era.
