The Story of Penicillin
Alexander Fleming was born on a farm in Scotland on August 6, 1881. He was the seventh of eight children. As a boy Fleming was never one to worry about neatness. He loved exploring the countryside with his eight siblings in the isolated area of Scotland in which they lived.
When he finished school, Fleming trained as a doctor. He liked experimenting with bacteria and germs and often grew cultures in unwashed, shallow, circular dishes. One day, Fleming accidentally made a big discovery that made him very famous. Fleming was going on holiday for two weeks. He left his London laboratory in a mess and left his window open by mistake. In his haste, he also forgot to clean up an old dish that he had smeared with a bacteria culture that he was studying. Soon after he left, a spore containing a rare strain of a fungus mould cal ed Penicil ium, drifted into his laboratory through the open window from another laboratory in the same building. By chance, it settled onto the messy culture dish with its bacteria. This mould was very much like that found on stale bread.
If that wasn’t lucky enough, the weather became colder and the room temperature briefly dropped, so the Penicil ium mould began to grow. The weather soon heated up again, and the bacteria on the dish sprouted like a weed. However, one spot did not grow. In fact the bacteria on that spot had died. That one spot caught Fleming’s attention when he returned from his holiday. It was the spot where the Penicil ium spore had settled and grown. Fleming believed he had discovered something very important. He said. “One sometimes finds what one is not looking for.” He cal ed this mould Penicil in.
Fleming careful y tested his new discovery on animals but without harming them, since he loved all living creatures. His discovery was made in 1929 and was printed in magazines, but no one showed any interest until World War II (1948), when it was used to save many lives. Today, Penicil in is used to treat all kinds of bacterial infections. Perhaps you have even had an antibiotic that contains Penicil in when e-classroom 2013
