Who was the discoverer of penicillin?

Penicillins are antibiotics that are routinely used for the treatment of various infections caused by sensitive bacteria.At the famous St.Mary's Hospital in the city of London was their finding, do you know Who is credited with the discovery?

On August 6, 1881, the bacteriologist Sir Alexander Fleming was born in Scotland.His brilliant studies made millions of human beings will save their lives thanks to the discovery of penicillin.He developed tasks as a microbiologist until the beginning of the First World War .

The first studies

One day in September 1928, more precisely on day 3, Alexander Fleming was growing different strains of bacteria in one of the laboratories of St.Mary´s hospital London.Upon returning after a well-deserved vacation he went to observe his crops and found that on a plate, that p or oblivion had been left uncovered, a mold spot of white color and circular shape had developed.jpg "alt=" Who was the discoverer of penicillin?

I also note that the bacteria as if it were by magic.Over time, I managed to identify that mold as a kind of Penicilium.The substance it exuded, I call it "mold juice".

The discovery of Penicillin

A year later, Alexander Fleming published the studies carried out and came to the conclusion that the fungus found “seems to have some advantages over the known chemical antiseptics.” It was here that I use it for first time the term " penicillin ".This is the origin of penicillin, the discovery of Fleming paves the way for the development of the first to ntibiotico effective in the history of medicine.Thanks to his contributions, Fleming was awarded the Nobel Prize in 1945.He died in London due to a heart attack in 1955 and was buried as a national hero in St.Paul's Cathedral in that city.

A famous popular legend

According to a well-known popular legend of that time, it is said that Alexander Fleming's studies were fully paid for by Winston Churchill's father.This was because Fleming's father saved Churchill's own life during World War, a fact that he could never be verified reliably.
