Penicillin is a medicine that kills bacteria and is used to treat people in modern medicine. Although it was first discovered in 1896 by Ernest Duchesne, it wasn’t used in medicine until the early 1900s. Penicillin went through many stages of discovery and development by scientists such as Alexander Fleming, Howard Florey and Andrew Moyer before it became a mass-produced drug. Ernest Duchesne was the first to actually discover penicillin. However, in 1928, Alexander Fleming was the first to actually take notice of its value and publish a study on it. Fleming first discovered the mold when he went on a month-long vacation and accidentally left a number of dishes out for the time of the trip. When he came back, Fleming noticed a mold had grown on each of the dishes. He investigated the dishes one by one and “After some experimentation, he found that the ring was bacteria-free, and that the mold was a rare spore called Penicillium notatum,” (Lane). Fleming then connected that the mold was the substance that had killed the bacteria on the dishes. In 1929, he published the results of his study and stated in it that penicillin could be important and have value if it were to be produced in mass quantities. This re-discovery would lead to more …show more content…
In 1938, Florey and Chain studied penicillin and how it was able to kill bacteria. They found how penicillin could be used on humans as a medicine, and worked to help treat wounded soldiers fighting in the war. So, the drug was mass-produced and used for troops on the war front, which ended up saving many lives (Connors). The penicillin was used on soldiers to kill the bacteria in their injuries to reduce infections. Penicillin was then used to save many lives of American soldiers in the war as a medicine. These early developments of penicillin were proved to be very important at the time of
The improvement of medicine over the course of the human successes gave great convenience to the people of today. Science has cured and prevented many illnesses from occurring and is on its way to cure some of the most dreadful and harmful illnesses. As the world modernizes due to the industrialization, so does the ways of medicine. Some cures are approached by chance, some, through intense, scientific measures.
The Factor of War in the Development of Penicillin The discovery, development and subsequent use of penicillin can be considered to be one of the most important breakthroughs in medical history. There were many factors, which were involved in the development of penicillin, and it could be argued that war was the most important, but other factors were also responsible. Alexander Fleming was working in London as a bacteriologist in 1928 when he noticed that a growth of a mould called penicillin produced a substance that actually killed the germs he was working on. He realised that this might be very important and a year later he wrote an article about his findings. However, Fleming did not have the facilities or the support to develop and test his idea that penicillin could fight infection, and he didn't develop it further.

Years later other scientists were also intrigued by the possibilities of penicillin and produced enough penicillin to prove that it was a useable antibiotic. The scientists from Great Britain were developing all of this during World War II, and unfortunately funding for their drug was unavailable due to the war. They decided to bring their concepts to the United States, and once enough was made, it was eventually used, to treat wounded soldiers during World War I.
With the earliest recordings coming from the Fifth Century B.C., streptococcus pyogenes, and more frequently, its symptoms have been prevalent among doctors and historians for hundreds of years. The first mentioning of streptococcus pyogenes is to be credited to Hippocrates, in which he describes the relative symptoms of the flesh-eating bacteria in its early stages. Then depicted by Billroth in 1874, patients carrying erysipelas were determined to have this certain bacterial infection. In 1883, the chain-forming bacteria were isolated by Fehleisen; and in the following year, Rosenbach applied the S. pyogenes name. Further advances in hemolytic and non-hemolytic studies were made by Lancefield in the 1930’s, in which the alpha, beta, and gamma subgroups of the hemolytic structures – detailed and defined by Schottmueller and Brown - were divided into serotypes.
Penicillin became the first manufactured antibiotic after physician Alexander Fleming published articles regarding this bacteria-disabling mold in 1928. Come 1932, penicillin was commonly used to treat infected war injuries, saving the lives of unnumbered soldiers (Lewis). Since then, penicillin has become a popular treatment for numerous infections ranging from respiratory illness to syphilis. As society realized the benefits of penicillin, physicians began producing antibiotics to fight an infinite number of illnesses.... ... middle of paper ...
Medicine in the middle ages was basic during a time when there were terrible illnesses, limited resources, and lack of medical knowledge. Despite not having access to all the advanced technology, medical knowledge, and amazing resources as we have today, they managed to treat some illnesses and diseases. The physicians were not able to figure out what caused the illnesses. There was not any access to antibiotics in the middle ages, which made it nearly impossible to cure the more critical diseases.
18). Even though those diseases were not his goal to cure it still made penicillin revolutionary for the time being. Fleming now knew how to make penicillin and started to mass produce it. In the 1930s during the upgrading process of penicillin Fleming himself was cured of severe conjunctivitis. Then in the 1940s the fully developed penicillin was created. The creation of penicillin cured a wide variety of diseases, which led to the world excelling in growth, and penicillin improved the way of medicine at the time. The variety of diseases cured by penicillin made it a must have antibiotic. Penicillin was used to cure multiple diseases including syphilis, gonorrhea, tuberculosis, gangrene, pneumonia, diphtheria, and scarlet fever ( Common Antibiotics ). All the diseases have one thing in common, they all have the ability to spread, some faster than others. When a disease is discovered people tried to make a cure. When penicillin was made diseases that were thought to never have a cure were cured. People began to demand that penicillin be sold in local pharmacies. Penicillin was released to help people with the variety of diseases curable by
Medicine in the Middle Ages We are very lucky today! When we are sick, we go and see the doctor, and he or she can usually make us better with the use of medicine. It wasn‘t like this in the medieval era.
Ernest Chain and Howard Florey with the knowledge of Flemings work were able to successfully purify an extract of penicillin for testing. The tested it in 1940 on mice, they concluded that those who were given the penicillin lived whereas the others did not. Later in 1945 all three men received the Nobel Prize for their contr...
Penicillin, derived from the mold Penicillium, is the first antibiotic to successfully treat bacterial infections on humans. It was accidentally discovered by scientist, Alexander Fleming. While Fleming was growing Staphylococcus, a serious and often deadly infection, in a dish, he noticed the bacteria had stopped growing after a mold found its way
The Chickenpox virus is a horrible and painful infection. The highly contagious virus, known as Chickenpox, can be a fatal disease if not properly taken care of. The Chickenpox disease, etiology, signs and symptoms, history, and prevention is important for every individual to know about so they can be aware. The Chickenpox infection has been researched throughout the years, and the CDC continuously informs people how important getting vaccinated is (National Institutes of Health, 2017).

Alexander Fleming started the history of antibiotics in the 1920's with his discovery of penicillin.When penicillin was first discovered and used widely, it was touted as a wonder drug, and consequently was used as one.Though not necessarily harmful to the patient penicillin was used for much more infections than it was able to combat.Today the same practice is observed in the medical profession, however at this point it is due more to the detriment of an uneducated public.Studies have been carried out that show the huge over usage of antibiotics.In the seventies Soyka et al, concluded, "60% of physicians surveyed gave antibiotics for the treatment of the common cold."[3], and by common knowledge the common cold is a virus, something that cannot be treated by an antibiotic.Nyquist
The discovery of antibiotics is attributed to Alexander Fleming who discovered the first antibiotic to be commercially used (Penicillin) in approximately 1928. An antibiotic, also known as an antimicrobial, is a medication that is taken in order to either destroy or slow the growth rate of bacteria. Antibiotics are integral to the success of many medical practises, such as; surgical procedures, organ transplants, the treatment of cancer and the treatment of the critically ill.
