Hace 5 días · penicillin, one of the first and still one of the most widely used antibiotic agents, derived from the Penicillium mold. In 1928 Scottish bacteriologist Alexander Fleming first observed that colonies of the bacterium Staphylococcus aureus failed to grow in those areas of a culture that had been accidentally contaminated by the green ...
Fleming was the first to discover the properties of the active substance, giving him the privilege of naming it: penicillin. He also kept, grew, and distributed the original mould for twelve years, and continued until 1940 to try to get help from any chemist who had enough skill to make penicillin.
In 1939, a team of scientists at the Sir William Dunn School of Pathology at the University of Oxford, led by Howard Florey that included Edward Abraham, Ernst Chain, Mary Ethel Florey, Norman Heatley and Margaret Jennings, began researching penicillin.
Alexander Fleming, Scottish bacteriologist best known for his discovery of penicillin in 1928, which started the antibiotic revolution. He was recognized for that achievement in 1945, when he received the Nobel Prize for Physiology or Medicine, along with Howard Walter Florey and Ernst Boris Chain.
Fleming explained in his 1929 paper in the British Journal of Experimental Pathology that "to avoid the repetition of the rather cumbersome phrase 'Mould broth filtrate', the name 'penicillin' will be used." The name thus refers to the scientific name of the mould, as described by Fleming in his Nobel lecture in 1945: I have been ...
In 1928 Alexander Fleming (1881–1955) discovered penicillin, though he did not realize the full significance of his discovery for at least another decade. He eventually received the Nobel Prize in Physiology or Medicine in 1945 .
The simple discovery and use of the antibiotic agent has saved millions of lives, and earned Fleming – together with Howard Florey and Ernst Chain, who devised methods for the large-scale isolation and production of penicillin – the 1945 Nobel Prize in Physiology/Medicine. Go to: BEGINNINGS.
