His discoveries were not taken seriously. He had even published his work. The development of penicillin from the mould was also a very slow and tedious process and therefore was not given much thought; even he halted his discoveries on it for a while. Interestingly, the two scientists continued research on penicillin after Sir Fleming had abandoned it, and were able to master how to produce it in large quantities and make improvements on it.

He painted using bacteria! That will not be the most astonishing thing.

The fact that he painted using bacteria would be it! Painter James McNeal Whistler urged the microbiologist to join a private art club, Chelsea Art Club, where the scientist painted using germs. Each alexander fleming biography cortacadie was painted using a different colour of bacteria and the colours only became visible one the bacteria developed in the canvas!

This is cool! It was during this time that he realized that while antiseptics worked perfectly well on shallow wounds, it was killing soldiers who had deep and more serious wounds. This was because he found out, the antiseptics were destroying both the good and the bad bacteria. The good bacteria are good in protecting the body and the antiseptics were destroying these as well.

There was no alternative on what to use, therefore treatment continued anyway! He completed school at the age of 16! Penicillin Molecular structure: Image- Wikimedia Commons. His academic life was very interesting. He received a scholarship at the age of 11, to join the Kilmarnock Academy when his academic prowess was discovered. He studied there for two years then moved to London.

Before that, he used to go on foot to school, the Darvel Academy which was an eight-mile trip! His first studies in London at the Polytechnic were actually in Business and Commerce!! He performed extremely well, so much so that the school moved him, two classes, forward so that he graduated at age 16! He got a job at a shipping company, which he did not enjoy and decided to study medicine.

Published papers During his active research years, he wrote a series of research papers and publications in the area of bacteria, the use of antibiotics and also the immune system. He published works on bacteriology, chemotherapy, lysozymes, penicillin, and immunology. He was knighted in to become Sir Alexander Fleming. Alexander Fleming achieved an epochal milestone in August that would revolutionize medicine.

Following a prolonged vacation with his wife and son, he returned to his laboratory on September 3 to find a cluster of Petri dishes he had left on his workbench. These dishes contained colonies of Staphylococcus bacteria, and an open window during his absence had allowed various microbes to contaminate the dishes. While examining the dishes, Fleming discerned a peculiar occurrence in one of them: a fungus was flourishing and systematically eradicating bacterial colonies in its vicinity, while bacteria farther away remained unaffected.

Determined to explore this discovery further and identify a superior natural antibiotic to lysozyme, Fleming ascertained that the fungus belonged to the Penicillium genus. He subsequently developed a liquid containing the bacteria-killing substance produced by this fungus. His research demonstrated that penicillin could effectively eliminate a wide spectrum of germs, encompassing pathogens responsible for ailments such as scarlet fever, pneumonia, meningitis, and diphtheria.

Crucially, penicillin exhibited non-toxicity and posed no harm to white blood cells. Clinical trials further revealed that penicillin was ineffective as a surface antiseptic. Despite these challenges, Alexander Fleming persevered in his research on penicillin throughout the s, although he did not achieve the breakthrough required to mass-produce the antibiotic.

That milestone was reached by others. In the early s, a team of scientists at the University of Oxford, led by pathologist Howard Florey and biochemist Ernst Boris Chain, successfully transformed alexander fleming biography cortacadie into the therapeutic medication that has since saved countless lives. In recognition of their collective contributions to the discovery and therapeutic applications of penicillin, Alexander Fleming, Howard Florey, and Ernst Boris Chain were jointly awarded the Nobel Prize in Medicine or Physiology in In his Nobel Prize acceptance speech, Alexander Fleming cautioned against the misuse of penicillin and the potential development of antibiotic resistance, a prescient warning for the future of medicine.

When he showed his finding to Merlin Price, his former assistant, Price rightfully remarked, "You have discovered lysozyme in the same way. On March 7,he named the new antibiotic penicillin. Fleming's first wife passed away in On April 9,Fleming married his second wife, Amalia, a Greek woman who died in The biologist himself suffered a heart attack and passed away on March 11,in his London home.

Alexander Fleming British bacteriologist. Date of Birth: He was awarded the Nobel Prize in and died on March 11, His parents, Hugh and Grace were farmers, and Alexander was one of their four children. He also had four half-siblings who were the surviving children from his father Hugh's first marriage. Fleming was a member of the Territorial Army and served from to in the London Scottish Regiment.

He entered the medical field instudying at St. While at St. Mary's, he won the gold medal as the top medical student. Fleming had planned on becoming a surgeon, but a temporary position in the Inoculation Department at St. 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.
