A new scientist futhers the development of penicillin.
Dr. Howard Florey began intensive research on penicillin. He demonstrated penicillin's ability to kill infectious bacteria. However, the war caused the scientists not to be able to produce the medicines, so he went to the United States for help. -
The production of penicillin.
Andrew Moyer and Dr. Heatley began to increase the yields of penicillin by 10 times. Then in 1943, the clinical trials showed that penicillin was the most effective antibacterial agent. -
Resistance to penicillin.
Four years after drug companies began to mass produce penicillin a microbes began showing that it could resist it. This bug was called Staphylococcus aureus. It was mostly harmless, unless it overgrew and became a toxin. -
The scientists get rewarded.
