In 1928, at St. Mary's Hospital, London, Alexander Fleming discovered penicillin. This discovery led to the introduction of antibiotics that greatly reduced the number of deaths from infection.
Alexander Fleming discovered the antibiotic properties of penicillin, produced by the mold Penicillium chrysogenum (shown here, also known as P. notatum).
The story of Alexander Fleming’s discovery of penicillin has been told often. Fleming was already well known for his earlier work on staphylococci when, upon returning from a long holiday in September 1928, he noted that one petri dish contained colonies of Staphyloccus except for clear area contaminated with a fungus that appeared to inhibit ...

Waksman approached the search for antibiotics in a novel and systematic way, unlike the chance discovery of penicillin by Fleming, who observed an accidental contamination of a bacterial pathogen by an airborne mold.
The antibiotic properties of penicillin were first noticed in 1928 by Alexander Fleming, a microbiologist at St. Mary's Hospital in London, when he saw nothing but dead bacteria surrounding the mold, later identified as Penicillium notatum, that contaminated a culture of staphylococcus bacteria.
Penicillin, the first effective antibiotic, was famously discovered by Alexander Fleming in 1928 almost by accident. The introduction of penicillin in the 1940s, which began the era of antibiotics, has been recognized as one of the greatest advances in therapeutic medicine.
En 1928, en el St. Mary's Hospital de Londres, Alexander Fleming descubrió la penicilina. Este descubrimiento hizo posible la introducción de antibióticos que redujeron en gran medida el número de muertes por infección.
way, unlike the chance discovery of penicillin by Alexander Fleming, who observed an accidental contamination of a bacterial pathogen by an airborne mold. Waksman and his students screened cultures by looking for growth inhibition zones surrounding single colonies of a series of isolated soil microbes on agar plates. They
The Penicillin Problem The story of the accidental discovery of penicillin by Alexander Fleming has been told often. Fleming was already well known for his earlier work on Staphylococci when, upon returning from a long holiday in September 1928, he noted that one petri dish contained colonies of Staphylococcus except for a clear area ...
