In many cases in science, many discoveries are made by pure chance, as happened for example to Alexander Fleming (Darvel (Scotland) 6 August 1881–London (England) 11 March 1955) who, while observing slides under a microscope in 1922, a few weeks after putting his nasal mucus on a Petri dish, noticed that cultures of microbes had developed all over the plate, except for his secretion. Subsequent experiments, performed with other mucus or with tears, showed him that an antibacterial substance was present in these liquids. From these casual intuitions, he opened the doors to the discovery of penicillin, the first substance with an antibiotic effect [1,2]. From this discovery, which only occurred a century ago, many antibiotic compounds were isolated from microorganisms, and many others were synthesized by organic and pharmaceutic chemists [3,4,5].

Abstract
In many cases in science, many discoveries are made by pure chance, as happened for example to Alexander Fleming (Darvel (Scotland) 6 August 1881–London (England) 11 March 1955) who, while observing slides under a microscope in 1922, a few weeks after putting his nasal mucus on a Petri dish, noticed that cultures of microbes had developed all over the plate, except for his secretion. Subsequent experiments, performed with other mucus or with tears, showed him that an antibacterial substance was present in these liquids. From these casual intuitions, he opened the doors to the discovery of penicillin, the first substance with an antibiotic effect [1,2]. From this discovery, which only occurred a century ago, many antibiotic compounds were isolated from microorganisms, and many others were synthesized by organic and pharmaceutic chemists [3,4,5].File | Dimensione | Formato | |
