Penicillin Discovery Essay

For those of you who don't know me already, my name is Mia. I'm here today to talk about penicillin, accidental invention that changed the world. First, I will tell how penicillin was discovered then say something about people that are charged for that. After that I will say something about Nobel prize. Finally, just before I finish I will say what is purpose of penicillin in our lives. At the end I'll be happy to answer your questions.

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

A majority of pharmaceutical companies thought that penicillin was to be a cure for any infection. At first no one expected that bacteria would mutate and become stronger. Initially pharmaceutical companies stopped doing research for new antibiotics and concentrated on other areas. As the result,

Penicillin brought about the biggest search in medical history. It was reasoned that if there was one antibiotic in nature, there must be many more, and there were.

It had the same curing properties as “M+B” (it cured infectious diseases), the only difference being that it also treated wounded soldiers. It greatly increased the survival rate of wounds and infectious diseases, and in my opinion, without Penicillin the death rate would have probably doubled or tripled! Like “M+B” the demand for Penicillin boomed during World War Two, and the mass production of the drug increased greatly.

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

Penicillin is a widely known life saving product that kills bacteria. The medicine was made on accident by Alexander Fleming.Little did he know, this mistake changed the whole world.To start off, Everyone has accidents, even professionals. Most of the time, the accidents that happen are for the worse. But, some accidents can be for the greater good. When scientists and inventors have accidents they could get burnt in a lab or cause a fire. But, other times they make tremendous things. Some huge inventions that changed the world are the microwave, play-doh, x-rays and many more. Velcro was also made on accident by a swiss electrical engineer by the name of George de Mestral. Jesse Lane says “Velcro was invented when George de Mestral noticed how certain types of burrs would cling to his clothes and his dog’s fur whenever he took him for a walk in the woods.” Thus creating velcro that is used on day to day items.In addition, penicillin is a very useful accidental

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

Furthermore, a scientist named Andrew J. Moyer had succeeded in increasing the yields of penicillin 10 times, and with the help of Dr. Heatley. The penicillin production quickly went available to treat the Allied soldiers wounded on D-Day. In the article “The History of Penicillin” it states, “the price dropped from nearly priceless in 1940, to $20 per dose, in July 1943, to $0.55 per dose by 1946. Because of their work, two members from the British groups were awarded the Nobel Prize, and Andrew J. Moyer was inducted into the Inventors Hall of

A group of Oxford scientists built upon the discovery by Alexander Flemming in order to mass produce penicillin. In the course of his research, Sir Flemming noticed that the secretions of a certain strain of mold, Penicillium notatum, killed surrounding bacteria. The purification of penicillin from the secretions, however, proved difficult. In the late 1930s, Howard Florey, Ernst Chain and others at Oxford University, “turned penicillin from a laboratory curiosity into a life-saving drug” (American Chemical). For their work on penicillin, Flemming, Florey and Chain were awarded the 1945 Nobel Prize in Physiology or Medicine. The first penicillin samples were unrefined and produced in milk jugs (Quinn, 427), but within five years, its distillation occurred at the industrial level. This was accomplished as a result of the implementation of an open network of information exchange. Roswell Quinn writes, “Mold samples, top-secret reports, and scientists began flying all over the country and, in some cases, the world” (Quinn, 427). Additionally, the cost of the drug’s development raised no concerns

“Over 50,000,000 peoples lives have been saved by the drug penicillin” (Sim). Today Penicillin and other antibiotics are crucial in the lives of people. One bad thing about penicillin is approximately 11.5% of the population is allergic to it so the diseases they receive that have to be healed by penicillin or other antibiotics might not heal as fast or maybe even kill them. Another negative aspect to Penicillin is it weakens the immune system(Cooper). Most of the body survives off of friendly bacteria and if antibiotics kill bacteria in large numbers, then it kind of defeats the purpose. Penicillin is used to treat many diseases and viruses that can be deadly if medicine was not applied, and they are easily accessible. After the discovery and processing of Penicillin, it was often described as the “Miracle Drug” and that is exactly what it was. Prior to the foundation of Penicillin, death was very common due to diseases that we think are no

After coming back from vacation, Dr. Alexander Fleming returned to his lab to find a different species of molds than expected on a dish. According to The History of Penicillin by Mary Bellis, Fleming observed the mold in a pure form and soon realized that the substance killed and number of disease killing bacterias.

As Dr. Andrew Fleming once said, “one sometimes finds what one is not looking for.” After returning from summer vacation in 1928, He would go on discover one of the world’s greatest accidents in his lab at St. Mary’s Hospital, London. Upon his arrival, he found his work bench scattered with various petri dishes that were previously contaminated with Staphylococcus Aureus but then replaced by a mold known as Penicillium Notatum that inhibited the growth of certain harmful bacterias. This mold would revolutionize modern medicine, as the world’s first true antibiotic. At the time of its discovery there was no cure for ailments such as pneumonia, gonorrhea, rheumatic fever or even blood poisoning. However this great magnitude of his discovery

The accidental discovery of penicillin in 1940 introduced an antibiotic that helped people all around the world. Penicillin has been one of the greatest advances in medicine to this very day. The discovery of penicillin first happened accidentally by a scientist named Alexander Fleming which took place in the United Kingdom. Before the discovery of penicillin there was nothing we could use to defend our bodies with against infections such as pneumonia, gonorrhea or rheumatic fever which at the time were extremely deadly but now because of the discovery of penicillin can be easily treated. Since this discovery happened during World War II, the United States played a huge and major role in the development of this newly discovered drug. This helped
