Alexander Fleming / Discover of Penicillin
Scottish bacteriolohist. Alexander Fleming
(1881-1955) studied substances that could ward off bacterial infections kids
efforts redoubled after world war 1 when a bacterial infection in the form of
trench fever and other afflictions tool more lives than combat in 1928 while
investigating the staphylococcus bacterium he discovered bacteria-free zone in
a culture where a patch of the mold Penicillium Sir Alexander
Fleming was a young bacteriologist when an accidental discovery led to one of
the great developments of modern medicine on this day in 1928.
Having left the plate of staphylococcus bacteria uncovered, Fleming noticed that a mold that
had fallen on the culture had killed many of the bacteria. He identified the mold
as
Penicillium notatum, similar to the kind found on bread. In 1929,
Fleming introduced his mold by-product called penicillin to cure bacterial
infections. Many school children can recite the basics. Penicillin was
discovered in London in September of 1928. As the story goes, Dr. Alexander
Fleming, the bacteriologist on duty at St. Mary’s Hospital, returned from a
summer vacation in Scotland to find a messy lab bench and a good deal more.
It took Fleming a
few more weeks to grow enough of the persnickety mold so that he was able to
confirm his findings. His conclusions turned out to be phenomenal: there was
some factor in the Penicillium mold that not only inhibited the growth of the
bacteria but, more important, might be harnessed to combat infectious diseases.
