The Discovery of Penicillin The discovery of penicillin was a huge milestone for the medical world and start of the antibiotic age. Penicillin was discovered by physician Alexander Fleming in 1928 and since then has been purified and used to treat many infectious diseases, saving millions of lives (Jacobs). Though the purification took a very long time, penicillin proved to be very helpful in treating common, but lethal infections (U.S. Library of Medicine). Since penicillin was discovered just before WWII, it was able to save many lives during the war. Soon after the discovery of penicillin, doctors referred to it as a “miracle drug” due to it’s ability to stop rapidly growing infections and save lives (NHS Choices).

It saved many lives in WWII and gained a great deal of attention when it was proven successful (PBS). The first truly successful test of the purified penicillin on the police officer really helped scientists progress in purifying penicillin (Jacobs). The next two tests of penicillin were on a teenage boy with a staphylococcal infection and an infant with a severe urinary tract infection. The drug proved to be completely successful in clearing up both of these infections. Doctors were so amazed at these recoveries they called penicillin a “miracle drug” …show more content…
The first step of making penicillin is growing the penicillium mold (US National Library of Medicine).. Scientists discovered shortly after the discovery of penicillin that they could easily grow the mold using deep fermentation in huge tanks with sugar and a bunch of other chemicals (NHS). After they grow the mold, they extract the penicillin from the mold, which can take awhile (US National Library of Medicine). Lastly, they perform the hardest step, purifying the penicillin so that it can be sent to hospitals (PBS).
Penicillin works to stop infections by a fairly simple, but also kind of confusing and hard to perform procedure of destroying the bacteria’s cell wall. It does this by activating an enzyme called transpeptidase. As soon as the transpeptidase comes in contact with the cell it starts deconstruction of the cell wall, which causes the organelles to become exposed and the cell to die. Penicillin usually takes a few days to start completely deconstruct the cell wall and kill all of the other bacteria cells, but as soon as it has broken down, the bacteria cell instantly dies (US National Library of Medicine,
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
Why was the invention of penicillin so important in the context of WWII? What were some other advances in medicine that were
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.
Fleming in 1928. Penicillin helped to treat some common infections: step throat, boils, it would heal wounds quicker, as well as treat more serious infections such as meningitis and pneumonia. Antibiotics usually kill only weak bacteria and after some years of antibiotic usage stronger bacteria have not only survived but also became resistant to the old cure. “Doctors have started to prescribe antibiotics to cure conditions such as ear infections, sinusitis, bronchitis, non-specific upper respiratory tract infections and even common colds and flu… According to the Director of Antimicrobial Resistance, Dr. Richard Besser, each year US physicians write $50 million worth of prescriptions that are ineffectual and unnecessary.” (Elisa Bussey). The more doctors were prescribing antibiotics, the bigger the number of people who become resistant to them. Most of the European countries prescribe antibiotics to kill bacteria only in cases of life threatening conditions. Patients in the US have become accustomed to receiving antibiotics for almost any health concerns and with time, patients have started to expect such prescriptions as a norm.
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.
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
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.
Penicillin has helped save many lives throughout the years. It has cured things like strep throat, which many people have had in their lives, syphilis, and gonorrhea. It also sparked a new wave of
Penicillin was a very important drug used in World War 2. During the war companies were forced to find a way to make penicillin on an industrial scale. This means that Penicillin was mass
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.
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
Howard Florey, a future Nobel Laureate , and three of his partners at Oxford University began research on penicillin and found penicillin ability to swiftly kill deadly bacteria. Unfortunately the ongoing war against Germany in World War II had stretched the Allies resources to far so when it became time for human testing the importance was placed on weapons not medicine. Lucky, Florey had had a Flame ignited in him to finish the research and save lives. Florey asked the United States for help and was referred to the Peoria Labs and on July 9, 1941, Florey and his colleague Norman Heatley arrived in the U.S.A. along with one of the most important inventions in history, a small of penicillin for the Americans to work on. After a intense worldwide search for the best strain of penicillin it was a cantaloupe in a market Peoria itself that was improved and modeled for use outside of the lab. Finally, on November 26, 1941, Andrew J. Moyer, with assistance from one Dr. Heatley, had succeeded!
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.
