This Day in History:, Penicillin Is Discovered .
September 28, 1928.
Penicillin was discovered by Scottish
bacteriologist Sir Alexander Fleming. .
Returning to St. Mary's Hospital in London after a
vacation, Fleming noticed that a mold had contaminated
Petri dishes of a common infectious bacteria.
Fleming was stunned to
realize that the Penicillium
notatum mold was preventing
the growth of the bacteria.
Fleming concluded that the Penicillium "mold juice"
could be manipulated to fight infectious diseases.
I certainly didn’t plan to revolutionize all medicine by discovering the world’s first antibiotic, or bacteria killer.
But I guess that was exactly what I did, Sir Alexander Fleming, via
'PBS News Hour'.
After 14 years of trial and error, penicillin was
perfected through the collaboration of Sir Fleming,
Dr. Howard Florey and Dr. Ernst Chain
