Alexander Fleming Quotes


It has been demonstrated that a species of penicillium produces in culture a very powerful antibacterial substance which affects different bacteria in different degrees. Generally speaking it may be said that the least sensitive bacteria are the Gram-negative bacilli, and the most susceptible are the pyogenic cocci ... In addition to its possible use in the treatment of bacterial infections penicillin is certainly useful... for its power of inhibiting unwanted microbes in bacterial cultures so that penicillin insensitive bacteria can readily be isolated.

Sir Alexander Fleming FRS FRSE FRCS was a Scottish physician and microbiologist, best known for discovering the enzyme lysozyme and the world's first broadly effective antibiotic substance which he named penicillin. He discovered lysozyme from his nasal discharge in 1922, and along with it a bacterium he named Micrococcus Lysodeikticus, later renamed Micrococcus luteus. His discovery of what is later named benzylpenicillin (or penicillin G) from the mould Penicillium rubens in 1928, is described as the "single greatest victory ever achieved over disease." For this discovery he shared the Nobel Prize in Physiology or Medicine in 1945 with Howard Florey and Ernst Boris Chain.
