it is one of the maximum well-known discovery testimonies in
history. In 1928, the Scottish scientist Alexander Fleming observed a micro
organism-filled Petri dish in his laboratory with its lid by chance ajar. The
sample had grow to be contaminated with a mold, and everywhere the mold turned
into, the bacteria become dead. That antibiotic mold became out to be the
fungus Penicillium, and over the next two a long time, chemists purified it and
developed the drug Penicillin, which fights a big variety of bacterial
infections in people without harming the humans themselves.
Penicillin turned into being mass produced and marketed by
way of 1944. This poster connected to a curbside mailbox suggested
international battle II servicemen to take the drug to rid themselves of
venereal disease.
