The story of the inventor of penicillin, what is the story of the origin of penicillin?

The inventor of penicillin was the British bacteriologist Alexander Fleming.

Alexander Fleming first discovered penicillin, which was further studied and improved by British pathologist Florey and German biochemist Chin, and successfully used to treat human diseases, and the three of them won the Nobel Prize in Physiology or Medicine.

With the discovery of penicillin, mankind found a drug with a powerful bactericidal effect, ending the era when infectious diseases were almost impossible.

One reason penicillin continues to stay ahead of the curve is that it is effective against many harmful microorganisms. The drug is effective for syphilis, gonorrhea, scarlet fever, diphtheria, as well as certain types of arthritis, bronchitis, meningitis, blood poisoning, bone infections, pneumonia, gangrene, and many other diseases.

In Scotland, England, a poor farmer named Fleming found a boy who had fallen into a cesspool, and he rushed to save the boy from danger.

Two days later, the father of a boy offered to repay him with a generous gift, but the farmer insisted that he would not accept it, repeatedly stating: "I cannot accept payment for saving your child." The gentleman continued

Well, since you have saved my child, then let me do my part for your son, let's make an agreement, please allow me to take your son away, I will give him a good education. If this child is as kind as his father, then he will surely become a person you will be proud of in the future. In view of the gentleman's sincerity, the farmer had no choice but to agree to his offer.

The farmer's child was sent to school, and he was also sent to St. Mary's Medical College until he graduated.

The farmer's child was none other than Professor Alexander Fleming, a famous British bacteriologist who first invented the world-famous penicillin in 1928. And the gentleman mentioned above is Winston Churchill, a member of the British House of Lords, whose son who was rescued by a farmer later became a famous British politician and Prime Minister Sir Winston Churchill during World War II.

The origin story of penicillin was first discovered by a British botanist, pharmacologist and biologist named Alexander Fleming。Penicillin is often used as a general term for a class of antibiotics, that is, penicillin antibiotics, which belong to the -lactam class of antibiotics. This type of antibiotic inhibits the synthesis of bacterial cell wall by acting on the penicillin-binding protein in the bacterial bacteria, so that the bacteria lose their permeability barrier and swell, lyse and die, and also dissolve the bacteria with the help of bacterial autolysus.

Origin of penicillin

The world's first antibiotic, penicillin, was introduced in 1941. Penicillin was discovered by the British bacteriologist Fleming from 1881 to 1955. In the autumn of 1928 he was a lecturer in bacteriology at St. Mary's College in London.

One day, while observing staphylococci bacteria, he noticed clusters of green mold growing on the agar used to grow bacteria, which was not surprising. Because many bacteriologists often have foreign microbial contamination in their laboratories, things are generally lost. Fleming, however, was unusually attentive.

He found that there was no staphylococcus around the mold, and that the staph bacteria in the glassware were gone. This serendipitous discovery fascinated Fleming. He managed to grow the mold, filtered the culture, dripped it into a staphylococcal glassware, and after a few hours all the staph bacteria died, and diluted the filtrate 800 times, and it still worked well.

PenicillinThe inventor was Alexander Fleming.

Sir Alexander Fleming, FRS (6 August 1881 – 11 March 1955), Scotland.

Biologist, pharmacist, botanist. The discovery of lysozyme in 1923 and penicillin (also known as penicillin) in 1928 pioneered the field of antibiotics and made him famous all over the world. In 1945, he was awarded the Nobel Prize in Medicine for his work with Florey and Chin for their work on penicillin.

Anecdote

There is a well-circulated, but untrue, story that Fleming's farmer father once saved Churchill as a child.

Churchill's father paid for Fleming's education, and Churchill himself fought in World War II.

was rescued from a dying illness due to penicillin.

Fleming's letter to a friend confirmed that this was a mistake and that the drug that later saved Churchill was sulfonamides rather than penicillin. The reason for this misinformation is most likely because sulfonamide is Bayer of Germany.

Laboratory discoveries, during wartime, propaganda agencies were reluctant to advertise drugs discovered by enemy countries, switching instead to penicillin, which was discovered by the British.

Penicillin was invented in 1928.

On September 15, 1928, Alexander Fleming was on vacation when a mold grew in an unwashed, discarded petri dish, so he invented penicillin.

Further trials have shown that this antimicrobial works slowly and is difficult to produce in large quantities. Before he moved on to other research projects, he published a ** in 1929 describing his findings, but this **** did not attract attention at the time.

In 1938, Howard Walter Flory, a pathologist at the University of Oxford, England, and Ernst Boris Chann, a German biochemist, happened to read Fleming's article and began to do purification experiments. In 1941 it was given to patients on trial.

With the encouragement of the British and American**, now pharmaceutical companies have entered this field and soon found a way to produce penicillin on a large scale. At first, penicillin was reserved for the war wounded, but by 1944 it was also available to British and American citizens in medical care. By the end of the war in 1945, the use of penicillin had spread throughout the world.

Summary. Penicillin was discovered by British scientist Alexander Fleming in 1928. At the time, he was working on some bacteria and accidentally left the experimental petri dish in the laboratory.

A few days later, he unexpectedly discovered that a fungus called penicillin was growing on the dish, and the surrounding bacteria were all suppressed. This suggests that penicillin may have the potential to kill bacteria. Subsequently, he conducted in-depth research on penicillin and found that it can ** many infectious diseases, such as pneumonia, meningitis, etc.

In 1945, Fleming was awarded the Nobel Prize in Medicine with two scientists for their contributions to the discovery and application of penicillin.

In 1945, Fleming and two scientists were awarded the Nobel Prize in Medicine for their contributions to the discovery and application of penicillin.

In addition to Alexander Fleming, two other scientists also made important contributions. One was Howard Flory, who tried to purify pure penicillin and successfully converted it into medicine; The other was Ernest Oxley, who was the first to use penicillin to cure the wounded during World War II and to make it a mass-produced medicine. The three scientists were awarded the Nobel Prize in Medicine for their contributions to the discovery and application of penicillin.

To be precise, penicillin was co-invented by British bacteriologist Alexander Fleming, Australian pathologist Frank Lory, and German biochemist Chin Chan. Because Fleming discovered penicillin, he was not a chemist and Chang ethnologist, and the storage of penicillin was not successful. Later, Flory and Chin saw Fleming's publication of penicillin, and then helped Fleming produce penicillin with high Xunchang purity.

So to be precise, the inventors of penicillin should be these three people. If I had to name only one, it would be Alexander Fleming, who contributed the most.

It was first discovered by Fleming in England.

Penicillin is a very effective antibiotic, which was discovered by the British scientist Fleming in 1928. Since then, penicillin has been widely used, saving countless lives. Fleming grew up in a poor family and had no money to go to school.

He was admitted to St Mary's School of Medicine, University of London, on his own. Later, when he participated in the field ambulance, he witnessed a large number of wounded Dan Liang being amputated or losing their lives due to wound infection. So, he was determined to find a new antibacterial and anti-inflammatory drug, and in the dark and damp basement, he worked hard.

During a culture of staphylococci from an infected wound, a blue-gray mold was accidentally found that killed the staphylococci. Dilute this blue-gray mold 800 times, and it can also stop the growth of staphylococci in the clump, and it will not damage normal cells. Fleming named it"Penicillin"i.e. penicillin.

This is the first antimicrobial discovered by humans.
