The Great Mistake
Have you ever reached in the refrigerator for your favourite snack and found it covered with a nasty-looking mold? In a way, that’s what happened to Alexander Fleming. He reached for one of his medical experiments and found it covered with mold.
It was August of 1928. Fleming was running experiments in his lab at St. Mary’s Hospital. He was working on germs called staphylococci. These germs cause illness in people. He tried to be very careful with the germs. But, he had not been careful enough. He looked down. He saw the splotchy, green mold, " Oh, bother, " he must have thought. " Now all my hard work is ruined. I have to start over.
Fleming was disappointed, but he was a thoughtful scientist. Before he threw out the experiment, Fleming looked at it more closely. Something strange was going on in the glass dish. At the edges of the mold, the germs were gone. Could the mold be killing the germs? Fleming knew what to do next—more experiments!
Fleming proved the
mold
could kill germs. He even proved the mold was not harmful to people. Next he wrote a paper on his work. He hoped people would give him money to make the mold a new medicine.
Sadly, no one was interested in his work. Fleming worked for twelve years until someone believed in his ideas. Finally in the 1940s, he teamed up with Howard Florey and Ernst Chain. Together they made a medicine from the mold. The medicine was called penicillin. It is still used by doctors today to cure many illnesses from bad sore throats to life-threatening brain fevers. Many people owe their health and even their lives to Fleming’s great mistake. [br] How does the writer of this text describe mold? It is a______, ______plant growth.
