Alexander Fleming

he thought the mold had released a chimical that prevented the bacterias growth.

Alexander Fleming discovered penicillin, the first antibiotic drug, which revolutionized medicine by treating bacterial infections effectively. This discovery helped solve the societal problem of infections and diseases that previously had high mortality rates. Penicillin played a crucial role in saving many lives and improving public health worldwide.

Alexander Fleming's mother, Grace Stirling Morton Fleming, was a farmer's daughter who later became a housewife and mother. She played a significant role in encouraging her son's interest in science and education.

Fleming's hypothesis was that the Penicillium produce a chemical that can kill ... Alexander Fleming was a scientist, born near Darvel in Ayrshire, Scotland.

The Nobel Prize in Physiology or Medicine 1945 was awarded jointly to Sir Alexander Fleming, Ernst Boris Chain and Sir Howard Walter Florey for the discovery of penicillin and its curative effect in various infectious diseases.

Alexander Fleming - doctor - was born in 1824.

Mold spores are extremely tiny, about the size of dust particles. They exist just about everywhere -- you are most likely breathing in a few of them into your lungs right this second. It just so happens that a few penicillum mold spores got into Fleming's petri dish; who knows how or when.

Alexander Fleming faced challenges in trying to isolate and purify penicillin, including obtaining enough of the substance in a pure form to be effective as a medicine. He also had to overcome skepticism from the medical community and pharmaceutical industry about the potential of penicillin as a revolutionary antibiotic. Lastly, Fleming had to find a way to mass-produce penicillin in order to make it widely available for treatment of bacterial infections.

Alexander Fleming collected data related to the antibacterial effects of Penicillium mold, particularly on Staphylococcus bacteria. He observed that the mold killed the bacteria, leading to the discovery of penicillin.

Alexander Fleming discovered penicillin on September 15, 1928. This marked a significant milestone in the field of medicine, as penicillin became the first antibiotic to be used in treating bacterial infections. Fleming's discovery revolutionized modern medicine and saved countless lives.

Sir Alexander Fleming was a Scottish biologist, pharmacologist and botanist. He is best known for his discovery of the enzyme lysozyme in 1923 and the antibiotic substance penicillin grown from mould in 1928.

Alexander Fleming discovered the antibiotic penicillin in 1928, but his discovery faced controversy as he initially failed to fully recognize its potential medical uses. This led to delays in its development and widespread use for treating bacterial infections. Despite this, Fleming's work laid the foundation for the use of antibiotics in modern medicine.

Alexander Fleming accidentally discovered the bacteria-killing properties of penicillin in 1928. This important discovery paved the way for the development of the first antibiotic and revolutionized medicine by providing an effective treatment for bacterial infections.

Both Alexander Fleming and Jonas Salk were renowned scientists who made significant contributions to the field of medicine. Fleming discovered penicillin, the first antibiotic used to treat bacterial infections, while Salk developed the first successful polio vaccine, preventing the disease that had caused widespread paralysis and death.

He qualified with distinction in 1906 and began research at St. Mary's under Sir Almroth Wright, a pioneer in vaccine therapy. He gained M.B., B.S., (London), with Gold Medal in 1908, and became a lecturer at St. Mary's until 1914. He served throughout World War I as a captain in the Army Medical Corps.

He was elected Professor of the School in 1928 and Emeritus Professor of Bacteriology, University of London in 1948.

Early in his medical life, Fleming became interested in the natural bacterial action of the blood and in antiseptics. He was able to continue his studies throughout his military career and on demobilization he settled to work on antibacterial substances which would not be toxic to animal tissues. In 1921, he discovered in «tissues and secretions» an important bacteriolytic substance which he named Lysozyme. About this time, he devised sensitivity titration methods and assays in human blood and other body fluids, which he subsequently used for the titration of penicillin. In 1928, while working on influenza virus, he observed that mould had developed accidently on a staphylococcus culture plate and that the mould had created a bacteria-free circle around itself. He was inspired to further experiment and he found that a mould culture prevented growth of staphylococci, even when diluted 800 times. He named the active substance penicillin.
