They discovered that penicillin was a powerful germ-killer that reduced the severity of infectious diseases and made procedures such as organ transplantation and open-heart surgery possible. [6] Their findings received media coverage, which helped attract funding from the United States Government to mass-produce penicillin during World War II ...
In 1963 the World Health Organization reported high levels of penicillin in milk worldwide. People who were allergic to penicillin could now get a reaction from drinking milk. [232] A committee chaired by Lord Netherthorpe was established in the UK in 1960 to inquire into the use of antibiotics in animal feed. In 1962, the committee recommended ...
Sample of penicillin mould presented by Alexander Fleming to Douglas Macleod in 1935. The discovery of penicillin was one of the most important scientific discoveries in the history of medicine. Ancient societies used moulds to treat infections and in the following centuries many people observed the inhibition of bacterial growth by moulds.
Commemorative plaque marking Fleming's discovery of penicillin at St Mary's Hospital, London. The laboratory in which Fleming discovered and tested penicillin is preserved as the Alexander Fleming Laboratory Museum in St. Mary's Hospital, Paddington. The source of the fungal contaminant was established in 1966 as coming from La Touche's room ...

Penicillium rubens is a species of fungus in the genus Penicillium and was the first species known to produce the antibiotic penicillin. It was first described by Philibert Melchior Joseph Ehi Biourge in 1923. For the discovery of penicillin from this species Alexander Fleming shared the Nobel Prize in Physiology or Medicine in 1945.

Antibiotics have stopped working: A worldwide crisis. People are in a molecular race against time. Bacteria is evolving faster than the level of antibiotic discovery, and antibiotic resistance has ...
In 1940 Abraham discovered penicillinase as the cause of bacterial resistance to antibiotics such as penicillin. [10] In October 1943 Abraham and Sir Ernst Boris Chain proposed a novel beta-lactam structure with a fused two ring system. [11] [12] This proposal was confirmed in 1945 by Dorothy Hodgkin using X-ray crystallography.
