Then in 1938 a team of British scientists happened to(60)about Fleming’s findings in an old medical journal. They made further(61)with the drug. They tested it on animals and then(62)human beings. In 1941, it was declared safe for use on humans. Soon penicillin was produced in large quantity and was used to(63)many infections(感染).
Penicillin is a very powerful drug.(64)can treat many kinds of infections. However, it has some bad effects. Sometimes it causes a skin problem or a light fever. And it can be fatal for people(65)are allergic(过敏性的)to it. That is why before you take a penicillin shot, the doctor gives you a test shot first.
