The history of penicillin follows observations and discoveries of evidence of antibiotic activity of the mould Penicillium that led to the development of penicillins that became the first widely used antibiotics. Following the production of a relatively pure compound in 1942, penicillin was the first naturally-derived antibiotic.
Penicillin molecules are small enough to pass through the spaces of glycoproteins in the cell wall. For this reason Gram-positive bacteria are very susceptible to penicillin (as first evidenced by the discovery of penicillin in 1928 [46]). [47] Penicillin, or any other molecule, enters Gram-negative bacteria in a different manner. The bacteria ...
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.
Sir Alexander Fleming FRS FRSE FRCS [2] (6 August 1881 – 11 March 1955) was a Scottish physician and microbiologist, best known for discovering the world's first broadly effective antibiotic substance, which he named penicillin.
With the discovery and subsequent large-scale production of the wonder drug penicillin, a project for the production of penicillin in Australia became a high priority defence need. Captain Bazeley was brought back from New Guinea , where he was a captain in the 2/8th Australian Armoured Regiment, to head the team given the task of producing ...
Her major academic contribution is a four volume book titled The Clinical Application of Antibiotics. [4] The first volume is dedicated to Penicillin and her research on that topic. The British Journal of Surgery published a review on the book in 1953 reading: "It is a veritable encyclopaedia for the use and abuse of penicillin. It surely must ...

[3] He was the only son of Joseph Florey, a bootmaker from Oxfordshire in England, who as a boy moved to London where Florey's grandfather established a bootmaking business.
