Discovery of Penicillin
The discovery of penicillin refers to Alexander Fleming's 1928 observation of antibacterial effects from a contaminated Penicillium culture.
Overview
In September 1928 at St Mary's Hospital, London, Fleming noted a zone of lysis surrounding a fungal contaminant on a Staphylococcus culture. He identified the mould as a Penicillium species and demonstrated that broth filtrates prevented bacterial growth without causing immediate toxicity to human leukocytes in vitro. Fleming published these preliminary laboratory observations in 1929 while noting difficulties in isolating the active compound.
Why it matters
Fleming's publication provided the starting material and premise for subsequent work by Howard Florey, Ernst Chain, and colleagues at Oxford to isolate stable penicillin. In the history of science, the event is frequently studied as a classic example of accidental observation coupled with laboratory recognition.
