Essay on The Discovery of Penicillin

Penicillin is an antibiotic that is used to treat infections caused by Bacteria. One may think that Penicillin has been around for a long time however, it was

The development of penicillin provided a major stepping stone for the practice of medicine, and has saved the lives of countless individuals since its synthesis.

In this reading there was many very interesting facts about penicillin. Penicillin was a breakthrough in the medical field in the 20th century. The scientist Alexander Fleming had accidentally spilled a vile of bacteria on to a plate of bacteria to his benefit he found that is had stopped the growth of bacteria. This accidental discover has benefited everyone in the world because we have to get these shots if we are infected, plus it saved many life’s in world war II. However, Penicillin is considered an antibiotic chemical that is created by living organism to stop the growth of bacteria and prevent an illness if people were to come into contact with this problem. Since the discovery and massive stock piling of this cure it has become less

Penicillin is a type of antibiotics. It fights nasty bacteria in a human body. Penicillin is used to help many different infections caused by bacteria. Penicillin was made for the soldiers in world war one, it was to help bullet wound infections and infections caused by lost limbs. Penicillin is made from extracting it from mould.

     World War II turning points are much more important than penicillin. If there were not any breaks for the American troops, then there would have been many more lives lost in the war than needed. Possibly, there would be more lives lost in the fighting than saved by penicillin in its fist two decades of public use.

World War II was a historical turning point not only for the basis of political power and war tactics, but also for drugs and medical advances. Between 1939 and 1945, new medical techniques were developed as a direct response to new weaponry. One of the more profound advances was penicillin, discovered in 1928 by Scottish scientist Sir Alexander Fleming. During the war, the drug helped reduce the overall number of amputations and

Since then penicillin has been used on the beaches on D-Day in Normandy to here on the homefront. As production increased the price plunged from priceless in 1940 to $.55 in 1946. To members of the British group, Dr. Howard Florey and Ernst Boris Chain were honored with the Nobel Prize in Medicine in 1945, Dr. Moyer was inducted into the Inventors Hall of Fame, and the British and Peoria Labs were named International Historic Chemical Landmarks. On May 25, 1948, Dr. Andrew Moyer was granted a patent for the method of mass production of

Jesse Lane says in Not-So-Dumb Luck, When he came back, he noticed that every dish he had left out in the open was covered in mold.” She later says, “The dish that had caught Fleming’s eye contained a staphylococci culture- in other words, it was chock full of bacteria- and while Fleming had been away, the culture had also grown a tuft of yellow-green mold.” And that was the beginning revolutionary history of penicillin. Later in the paragraph the author says, “After some experimentation, he found that the ring was bacteria free, and that the mold was a rare spore called Penicillium notatum,” Where the name penicillin comes from ”which had wafted on air currents into his lab from another floor.” If he hadn’t gone on vacation and left his lab a mess then penicillin wouldn’t be with us today saving lives.Thirdly, penicillin is a widely used medicine that kills bacteria and treats

Penicillin had begun to be mass produced in the United States and sent over to help wounded Allied soldiers. Florey traveled to North Africa where he conducted his trials and save lives. The Australian government was now manufacturing penicillin while the U.S. and Britain were as well. Since it was government, they were able to be informed of the newest techniques for producing the substance. Florey’s team took a visit to the Australian laboratory to learn these up to date methods of production. This may be the case to why the 1945 version of penicillin was about 20 times more potent than the 1939 version. This deep fermentation penicillin was established 1945 at the Castle Bernard. Before, it was developed in a less efficient process by

They were working on it around World War II, they believe that the medicine had potential. They wanted to find a way to use the medicine on humans to help reduce the bacteria infections in a wound. When they did find a way, it mass-produced and used in the war. The medicine saved many lives. The scientist Florey, Chain, and Fleming were awarded the Nobel Prize. Fleming was alone credited with the penicillin discovery. Even though the discovery of penicillin was a simple accident, but all the series of events that led up to being a very useful medicine.

The onset of World War II made the drug very essential to the recovery of soldiers. It prevented millions of deaths and amputations, and the number of units sold in the United States increased from 400 million to 650 billion units per month in just two years. The number of casualties would have been drastically larger without penicillin since minor injuries would have proliferated into fatal infections. This antibiotic not only had short-term effects, but also had long-term effects since penicillin remains the most widely used drug today. Strep throats can be easily and cheaply treated now, but around seventy years ago, people would have died because of this

“In 1938, Howard Florey and Ernst Chain began to study penicillin” (Connors 126). This is important because it means extensive research was being done to figure out a way for penicillin to be applied on humans. “Part of the reason for their increased effort in discovering how penicillin could be used on humans was that a drug was needed to reduce bacterial infections in soldiers’ wounds” (Connors 126). This means there was a need for the development of penicillin, this fact probably motivated the scientists. In the end, without the development of penicillin, it could not have become such a widely used

The own Alexander Fleming indicates that the discovery occurred on 28 September 1928 and that this was accidental. I believe that all of us know how the penicillin was discovered: some bacterial cultures were contaminated by the fungus. He observed that a part of one of the cultures the bacterias had been destroyed by one of this pollutant.

Before Alexander Fleming founded penicillin,a French medical student Ernest Duchesne first noticed penicillin. In 1897, he first recorded his finding on a piece of paper differentiating molds and microbes. Ernest first came across clues for developing penicillin when he was in the Military Health Service School in Arabia. He saw that the stable boys at the hospital kept their saddles in dark and damp rooms to intentionally let mold grow.When Ernest ask the reason for these peculiar actions, the stable boys told him that the mold would heal the saddle sore on horse.Ernest then take this information and decided to test it on guinea pigs. Ernest Duchesne extracted substances from penicillium glaucum and successfully cured typhoids in guinea pigs,

Similar to Corn Flakes, Silly Putty, etc, penicillin was not made for its original intention and was an accidental discovery. Bacteriologist Alexander Fleming had left his laboratory a mess when he went on a vacation. When he arrived back to continue his work, he recognized that all the petri dishes he left out were congested with mold. Then, one dish that “contained a staphylococci culture” with a ring around the mold had drawn attention to Fleming. Stated from “Not-So-Dumb-Luck”, “. . . he found that the ring was bacteria-free, and that the mold was a rare spore called Penicillium notatum”. Since Fleming had a mycology lab downstairs and wasn’t the tidiest of experimenters, the mold most likely originated from the lab below and may have interacted with one of the cultures of the dishes. It was realized that the bacteria in the dish was killed by the mold, thus Alexander Fleming researched how the bacteria was exterminated. Eventually, he concluded that “penicillin was the antibacterial agent in the mold”, however he couldn’t determine its use for humans. The discovery of penicillin was entirely of nature’s work and an accident, admitted by Fleming.
