Pencillium Notatum: The Invention Of Penicillin

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.

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

In 1928, Alexander Fleming discovered that the mold penicillium notatum could be used as an antibiotic. It was not until 1940 that penicillin was derived from the mold to be used to treat disease and sickness. Norman G. Heatley asked a team of scientist to begin working on isolating the ingredient penicillin from the mold itself. In March of 1940, the team withdrew acidified culture

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

In 1929 Fleming published his findings to a British Journal of Experimental Pathology, referencing that penicillin had potential of therapeutic benefits. Dr. Fleming was never able to purify his samples of penicillin, but he became the first person to publish the news of its germ-killing power. Howard Florey, Ernst Chain and Norman Heatley expanded on Fleming 's work in 1938, at Oxford University.

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

Penicillin is an antibiotic used in fighting infections. A Scottish scientist named Alexander Fleming discovered penicillin in 1928. One of the first examples of the power

The disclosure by Alexander Fleming of penicillin opened up a totally new time of chemotherapy. Antibiotics are the chemotherapeutic specialists that kill or inhabit the development of microorganisms. These substance operators are utilized to treat malady by wrecking pathogenic microorganisms or restraining their development at focus sufficiently low to enough to avoid undesirable harm to the host (Dafale et al., 2016).

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

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

Fleming’s work was later expanded by Howard Florey and Ernst Chain and their team at Oxford University beginning in 1938, about ten years after Fleming’s first findings. They were able to transform penicillin as a curiosity in the lab and antiseptic to the life-saving antibiotic we know it as today. Howard Florey was deemed at an early age by his older sister who was a medical student at the time to be the next “Pasteur” due to his interest in pursuing medical research. Florey then achieved much as a student at the University of Adelaide, which at that time didn’t specialize in researchers, but in preparing general practitioners. Howard then went on to receive the Rhodes Scholarship to study in England at Oxford University. He used this opportunity as a springboard to going on to study in America and return back to England to Oxford University achieve much greatness. In 1938, he became the director of the Sir William Dunn School of Pathology. After a few years of taking on a variety of experiments and gathering a team of trusted professionals, he spearheaded work on the self-proclaimed “Penicillin Project” after coming across and sifting

In this case, the medicine was accidently discovered by a bacteriologist named Alexander Fleming. So Fleming was on a one month vacation, and he didn’t keep a neat and clean lab. In the source “The Discovery of Penicillin” the article says “it’s possible that one of these mold spores would interact with one of the cultures.” When the mold grew, it seem that it has killed the bacteria in the culture. Later on Fleming wrote a paper on his discoveries, and that the penicillin was the antibacterial

In 1928, Scottish scientist Alexander Fleming discovered penicillin for the first time. His discovery was an accident: he was in his laboratory and noticed that a window had been left open overnight. A Petri dish containing Staphylococcus bacteria was now growing blue-green mould.

The first antibiotic, penicillin, was discovered by Alexander Fleming in 1928. This antibiotic was used during World War Two. However in 1945, Alexander Fleming warned the public that they would most likely overuse penicillin, resulting in an evolution of bacteria. In 1952, antibiotic resistance was discovered by an unnamed researcher. This researcher found that some strains of bacteria were becoming strong enough to be immune to some medicines.
