How Did Penicillin Changed The Whole World

The wonderful discovery of Penicillin, a medicine that was discovered in 1928. This medicine was used to cure bacteria in humans. Penicillin had good results not only in the 1928, as it also still is very successful today. Penicillin had a big impact, it cured many people in the U.S. during World War II. penicillin,leads to the development of others antibiotics.

In 1928 Dr. Alexander Fleming began to sort through a pile of petri dishes containing colonies of bacteria that causes boils, sore throats, and abscesses. As he sorted through the dishes he noticed something unusual on one dish. It was dotted with colonies, and one area had a blob of mold growing. The area of mold was later identified as a rare strain of Penicillium notatum, the mold had secreted something that inhibited bacterial growth. Fleming later uncovered that this mold was capable of killing a wide range of harmful bacteria such as streptococcus, meningococcus and the diphtheria bacillus, that had played humanities. Prior to the discovery of Penicillin, Sulfa drugs were used during World War II. These drugs were name as the “wonder drug”. Although they’re still used today, Sulfa drugs were used to cure bacterial infections such as UTIs and gonorrhea. The new found drug penicillin, would cure millions and replace the use of Sulfa drugs.

In September of 1928, a rushed bacteriologist Dr. Alexander Fleming let his lab at St. Mary’s Hospital, as usual, a mess on his way to a month vacation. Little did he know he had just spawned one of the most crucial inventions of all time. Upon his return to his laboratory he found mold had grown in the petri dishes he had left out. One of whom contained the rare spore Penicillium notatum that had probably wafted up into his lab through the air currents from the down-stairs mycology lab. Dr. Fleming noticed a ring around the mold, and it was 100% bacteria free! Curiosity urged him onward, as he grew a pure culture of the mold and discover that it killed a great deal of disease-causing bacteria. He would go on to name the substance penicillin.

While some discoveries occur after years of painstaking research backed by times of frustration and the urge to give up completely, others occur after a mistake in a singular moment. Similar to the finding of X-rays and matchsticks, the discovery of penicillin by Sir Alexander Fleming in 1928 took place due to a complete accident.

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.

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

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

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.

“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

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.

Fleming began to sort through petri dishes containing colonies of Staphylococcus, bacteria that cause boils, sore throats and abscesses. He noticed something unusual on one dish. It was dotted with colonies, except for one area where a blob of mold was growing. The zone immediately around the mold—later identified as a rare strain of Penicillium notatum—was clear, as if the mold had secreted something that inhibited bacterial growth (American Chemical Society). The first introduction of penicillin began in the 1940’s, it was recognized as one of the greatest advances in therapeutic medicine. The discovery was made in the United Kingdom but because of World War II, the United States developed a large production of the drug. By 1937, an important pain killer known as methadone was introduced. Morphine, the most active substance in opium, is a very powerful painkiller that hooked many US Civil War soldiers (Drug Free World). They were wanting to find a painkiller that was less addictive to use for surgery and that’s why they invented

In 1928 Sir Alexander Fleming discovered penicillin when he left a plate of staphylococcus uncovered on a plate for two weeks. He was a chemist studying enzyme lysozyme, and rarely kept his laboratory clean. Instead of what one would assume would happen if one left a deadly disease unattended, penicillium notatum, similar to the mold on bready, had killed a large portion of the disease the bacteria. Fleming drew the conclusion that penicillin notatum could potentially treat bacterial infections by somehow killing off the bacteria, which led to testing and eventually mass-marketing of the product penicillin. (American Chemical Society, Alexander Fleming Discovery and

The discovery of penicillin was one of the most important discoveries in the 1900s and marks a turning point in human history. Penicillin was one of the world’s first antibiotics which eventually evolved into modern antibiotics that are used today; it has often been described as a miracle drug. The discovery of penicillin meant that doctors finally could completely cure their patients of deadly diseases. After World War I, many soldiers died from infected wounds because the antiseptics used, killed the patients’ immunological defences more than they killed the invading bacteria. Penicillin kills bacteria by destroying the cell wall of the microorganism causing the cell to burst; it was very effective in clearing bacteria without harming the

To begin, Penicillin became a widely used medicine for many reasons. One reason it became widely used was because how it was discovered. It was discovered by Alexander Fleming. Alexander went on a month long vacation, and came back to his lab cultures being covered in mold. One particular culture looked different, he noticed that the mold on that culture killed all the bacteria in it. Alexander did a bunch of experiments and discovered that the mold could kill bacteria and that could benefit humans. According to the text “It seemed that as it had grown, the mold killed the bacteria in the culture.” This quote means that if the mold could kill the bacteria in the culture than it could kill the bacteria in a human.

by Dr. Alexander Fleming. As test continued, Fleming began to realize that he was on the verge of a great discovery. However, he still did not know the identity of the fungus, and had little knowledge of fungi. His crude extracts could be diluted 1,000 times and still be effective in killing bacteria. After years of working on penicillin and going nowhere, many of his co-workers grew tired of hearing about it. The first real test for penicillin came when a 48-year-old police officer nicked himself shaving. After a time, Alexander's face became infected and he developed a temperature. When he was rushed to the hospital, the doctors believed that he had only hours
