Mary's, he won the gold medal as the top medical student. Mary's Hospital changed his path toward the then-new field of bacteriology. There, he developed his research skills under the guidance of bacteriologist and immunologist Sir Almroth Edward Wright, whose revolutionary ideas of vaccine therapy represented an entirely new direction in medical treatment.

He worked as a bacteriologist, studying wound infections in a makeshift lab that had been set up by Wright in Boulogne, France. Through his research there, Fleming discovered that antiseptics commonly used at the time were doing more harm than good, as their diminishing effects on the body's immunity agents largely outweighed their ability to break down harmful bacteria — therefore, more soldiers were dying from antiseptic treatment than from the infections they were trying to destroy.

Fleming recommended that, for more effective healing, wounds simply be kept dry and clean. However, his recommendations largely went unheeded. Returning to St. Mary's after the war, inFleming took on a new position: assistant director of St. Mary's Inoculation Department. He attended lectures at the Polytechnic School and worked for 4 years in a shipping office.

In an uncle left Fleming a legacy that enabled him to study medicine, and he entered St. In Fleming received his licentiate from the Royal College of Physicians. He chose a career in bacteriology and immediately joined the Inoculation Department, now the Wright-Fleming Institute, where he spent his entire career. He assisted Sir Almroth Wright, the originator of vaccinotherapy therapeutic inoculation for bacterial infection and the first doctor to use antityphoid vaccines on human beings.

Fleming's research at this time primarily involved the use of Paul Ehrlich 's Salvarsan in the treatment of syphilis. In Fleming passed his final medical examinations, winning the Gold Medal of the University of London. He was awarded the Cheadle Medal for his thesis "Acute Bacterial Infections," which foreshadowed the line of work he followed throughout his life.

He noticed that phagocytosis the ingestion and destruction of infectious microbes by the cells was more active in war wound infections than in ordinary wound infections, and he advised surgeons to remove all necrotic tissue as soon as possible. He observed that antiseptics not only did nothing to prevent gangrene but actually promoted its development by destroying leukocytes.

Philosophical or nonscientific topics were generally beyond his range. He contributed a few individual chapters or sections to composite works and committee reports and was author or coauthor of two books in his own special fields. Among his best papers were those prepared as addresses for endowed lectureships. Certain of these are included in the appended representative list.

A Collection of his published works and unpublished manuscripts—including letters, diaries, laboratory notebooks, and many other documents relating to Fleming—is deposited with the Sir Alexander Fleming Museum in the Wright-Fleming Institute. Voureka, I. Kramer, and W. Secondary Literature. London, ; Penguin ed. Lady Fleming persuaded Maurois to undertake this very readable biography, which shows occasional bias and contains some inaccuracies.

Various short appreciations and unusual photographs of Fleming were published in St. Special references are E. Abraham, E. Chain, C. Fletcher, H. Florey, A. Gardner, N. Heatley, and M. Chain, H. Heatley, M. Jennings, J. Fleming had teased Allison of his "excessive tidiness in the laboratory", and Allison rightly attributed such untidiness as the success of Fleming's experiments, and said, "[If] he had been as tidy as he thought I was, he would not have made his two great discoveries.

When he added nasal mucus, he found that the mucus inhibited the bacterial growth. In the next test, he used bacteria maintained in saline that formed a yellow suspension. Within two minutes of adding fresh mucus, the yellow saline turned completely clear. He extended his tests using tears, which were contributed by his co-workers. As Allison reminisced, saying, "For the next five or six weeks, our tears were the source of supply for this extraordinary phenomenon.

Many were the lemons we used after the failure of onions to produce a flow of tears The demand by us for tears was so great, that laboratory attendants were pressed into service, receiving threepence for each contribution. His paper describing his discovery was received with no questions asked and no discussion, which was most unusual and an indication that it was considered to be of no importance.

The following year he read a paper on the subject before the Royal Society, Burlington House, Piccadilly and he and I gave a demonstration of our work. Again with one exception little comment or attention was paid to it. As this substance has properties akin to those of ferments I have called it a " Lysozyme ", and shall refer to it by this name throughout the communication.

The lysozyme was first noticed during some investigations made on a patient suffering from acute coryza. With Allison, he published further studies on lysozyme in October issue of the British Journal of Experimental Pathology the same year. This indicates one of the major differences between pathogenic and harmless bacteria. His research notebook dated 21 November showed a sketch of the alexander fleming biography cortall plate with a small note: "Staphyloid coccus from A.

When I woke up just after dawn on September 28,I certainly didn't plan to revolutionize all medicine by discovering the world's first antibiotic, or bacteria killer. But I suppose that was exactly what I did. He was already well known from his earlier work, and had developed a reputation as a brilliant researcher. Inhe 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.

Before leaving for his holiday, he inoculated staphylococci on culture plates and left them on a bench in a corner of his laboratory. He suspected it to be P. La Touche identified it as P.
