What was the name of the mold that inhibited the growth of Staphylococcus aureus?
The mold, later identified as Penicillium notatum (now classified as P. chrysogenum ), had inhibited the growth of the bacteria.
Why did Fleming investigate further?
Fleming decided to investigate further, because he thought that he had found an enzyme more potent than lysozyme. In fact, it was not an enzyme but an antibiotic—one of the first to be discovered. By the time Fleming had established that, he was interested in penicillin for itself.
What was Fleming's greatest contribution to the understanding of how the body fights infection?
Fleming’s study of lysozyme, which he considered his best work as a scientist, was a significant contribution to the understanding of how the body fights infection. Unfortunately, lysozyme had no effect on the most-pathogenic bacteria.
What was Fleming's first discovery?
In November 1921 Fleming discovered lysozyme, an enzyme present in body fluids such as saliva and tears that has a mild antiseptic effect. That was the first of his major discoveries. It came about when he had a cold and a drop of his nasal mucus fell onto a culture plate of bacteria.
Why was Fleming's role emphasized by the press?
Fleming’s role was emphasized by the press because of the romance of his chance discovery and his greater willingness to speak to journalists. Fleming was knighted in 1944. In 1949 his first wife, who had changed her name to Sareen, died.
Who is Alexander Fleming?
Alexander Fleming is a notable name in biomedical research. He is credited with the discovery of penicillin, which led to the development of antibiotics for medicinal use. This article discusses Fleming and his contribution to the scientific community.
Where did Alexander Fleming go to medical school?
In 1903, Alexander Fleming enrolled in St. Mary's Medical School, where he received training in biomedical research and microbiology.
What did Fleming notice about mold?
However, he also noticed that the mold created a zone of inhibition, which is an area where bacteria cells won't grow.
What is the significance of Alexander Fleming's discovery of penicillin?
Lesson at a Glance. The development and use of antibiotics today can be attributed to Alexander Fleming's accidental discovery of penicillin. The inhibitory effects of mold on bacteria created a zone of inhibition, which can ultimately be used to fight infection in the body. Today, penicillin is used to treat common infections.
Who discovered mold in bacteria?
Prior to Fleming's work, several other scientists had proposed the antimicrobial effects of mold on bacteria. Ernest Duchesne, also a notable scientist, proposed the inhibitory effects of mold on bacteria as early as 1897. But this discovery was not taken seriously due to the lack of isolation and stabilization of the active penicillin molecule.

What did Fleming show about bacteria?
Using cells on a slide, he was able to show that chemical antiseptics in dilutions harmless to bacteria actually damage white blood corpuscles (leukocytes) —the body’s first line of defense. After World War I, Fleming continued to work on leukocytes and antisepsis.
What is the substance that Fleming found in blood?
Fleming and a colleague subsequently detected this substance, which he named lysozyme, in human blood serum, tears, saliva, milk, and a wide variety of other fluids. In its natural state lysozyme seemed to be more effective against harmless airborne bacteria than against disease-causing bacteria.

Work
Among microorganisms, life is a constant battle for survival. Alexander Fleming became interested in this. He used to leave bowls with bacteria cultures standing by his worktable. In 1928 he saw that in addition to bacteria, a mold fungus had begun to grow in a bowl and that the bacteria's growth had been impeded in the vicinity of the mold.

What did Alexander Fleming find?
Whilst cleaning the culture dishes one day he saw a mould growing on one of the plates. This in itself was not unusual, but on this occasion there were no germs growing around the growth. Curious as to what caused the germs to stop growing, and eager to find out what the mould was, Fleming grew more of it and experimented. He found that the mould acted against anthrax and diphtheria without creating any harmful side effects . This was the first occasion that an antibiotic drug had been developed (an antibiotic is something naturally produced by living organisms, rather than being a chemical compound). The new drug was a member of the penicillin notatum family, known popularly as penicillin.
Who discovered penicillin?
Alexander Fleming discovered Penicillin. Penicillin was discovered by chance in his laboratory. The experiments surrounding the discovery of Penicillin led to it being recognised as potentially valuable. Fleming published his findings on the discovery and properties of Penicillin. These findings were later used by Florey and Chain to develop Penicillin into a mass produced medicine. During the Second World War the US Government financed work on the production of Penicillin as it had the potential to save many soldiers lives.

Approaches to Fighting Infectious Disease
- Fleming accepted a post as a medical bacteriologist at St. Mary’s after completing his studies, and in 1906 he joined the staff of the Inoculation Department under the direction of Sir Almroth Wright. Wright strongly believed in strengthening the body’s own immune system through vaccine therapy, not by chemotherapy—the introduction of external chem...
