Question

Before doctors could prescribe antibiotics (medicines that kill bacteria), many people were badly affected each year from illnesses that are now easily treated. The first antibiotic was discovered by a Scottish professor named Alexander Fleming in 1928. Fleming was researching bacteria in a hospital in London, England, when he left to go on vacation for two weeks. While he was gone, he left samples of bacteria sitting out in his laboratory. When he returned, he found that one of the samples had been polluted by white mold. When he was preparing to dispose of the moldy sample, Fleming noticed something unusual. The bacteria near the mold had unexpectedly stopped growing. Fleming began to experiment and soon discovered that liquid from the mold could also kill other harmful bacteria. Fleming wrote about what he discovered, and other scientists wanted to know more. Other researchers continued Fleming's work in the hope that they could use the discovery to treat disease. They developed penicillin, an antibiotic which was soon being used around the world. Over time, many more antibiotics have been developed.
