In 1928, he studied the variation of Staphylococcus aureus grown under natural condition, after the work of Joseph Warwick Bigger, who discovered that the bacterium could grow into a variety of types (strains). [27] On 3 September 1928, Fleming returned to his laboratory having spent a holiday with his family at Suffolk.
Glass phial of British Standard penicillin. 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 ...
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.

The medicinal importance was discovered by Alexander Fleming, a physician at St Mary's Hospital, London. In September 1928, Fleming found that one of his bacterial cultures (of Staphylococcus aureus) was contaminated with mould, and that the area around the mould inhibited bacterial growth. He gave the name penicillin for the purported ...
