Penicillin discovery

Penicillin discovered by Sir Alexander Fleming Sir Alexander Fleming was a young bacteriologist when an accidental discovery led to one of the great developments of modern medicine on September 28. Penicillin was discovered by a Scottish physician Alexander Fleming in 1928. While working at St Mary's Hospital, London, Fleming was investigating the pattern of variation in S. aureus. He was inspired by the discovery of an Irish physician Joseph Warwick Bigger and his two students C.R. Boland and R.A.Q. O'meara at the Trinity College, Dublin, Ireland, in 1927 The discovery of penicillin and the initial recognition of its therapeutic potential occurred in the United Kingdom, but, due to World War II, the United States played the major role in developing large-scale production of the drug, thus making a life-saving substance in limited supply into a widely available medicine. Contents . Alexander Fleming's Discovery of Penicillin; Penicillin. Penicillin is one of the earliest discovered and most widely used antibiotic agents. While Sir Alexander Fleming is credited with its discovery, it was French medical student Ernest Duchesne who first took note of the bacteria in 1896. Fleming's more famous observations would not be made until more than two decades later

In 1928, bacteriologist Alexander Fleming made a chance discovery from an already discarded, contaminated Petri dish. The mold that had contaminated the experiment turned out to contain a powerful antibiotic, penicillin. However, though Fleming was credited with the discovery, it was over a decade before someone else turned penicillin into the miracle drug that has helped save millions of lives Die Entdeckung des Penicillin war ein Zufall. 1928 experimentierte der Mikrobiologe Alexander Fleming in seinem Labor mit Staphylokokken, das sind Krankheitserreger, die beispielsweise bei einer Lungenentzündung vorkommen. Dabei entdeckte er, dass eine seiner Bakterienkulturen von den Sporen eines Schimmelpilzes befallen worden war. Als er die verunreinigte Probe wegwerfen wollte fiel ihm auf.

To the left: the stark contrast of modern antibiotics, and the temperance with which they should be prescribed to minimise resistance: it's about management, not victory, explains curator Marie-Louise Kerr. MECHANISM OF ACTION Penicillins are bactericidal antibiotics as they kill the microorganisms when used at therapeutic dose. The synthesis of cell wall of bacteria is completely depended upon an enzyme named as transpeptidase. Primarily, Penicillin inhibits the cell wall of bacteria by blocking transpeptidase after binding to penicillin-binding protein (PBP) and prevents its synthesis The Discovery of Penicillin.

Der Zufall hat bei der Entdeckung des Penicillins eine große Rolle. At the time of his discoveries most of his research was revolved around finding a cure for scarlet fever, pneumonia, diphtheria, and typhoid fever.
