He saw that a mould was growing around the staphylococcus this mould produced a bacteria-free ring around itself. Two other scientists, Florey and Chain, developed penicillin into an effective drug. Penicillin was tested for over 20 years on both humans and animals. In 1941 scientists noticed that even low doses of penicillin that were produced prevented many deadl... ... middle of paper ... ...ields of medicine, healthcare, internet technology and business.

However, frequent mutations of bacteria cause today’s strains to become more resistant. One of many ways which bacteria undergo mutation is through horizontal transfer of genes (Lindsay J.A., 2013). The war against disease is a battle that humanity has fought for centuries, and only recently has the development of penicillin switched that tide of war in our favor. However, with the advent of methicillin resistant staphylococcus aureus and even vancomycin resistant staphylococcus aureus, the prospect of this battle is not promising (Bobenchik et al., 2013). Thus, it is crucial to test bacteria for antibiotic resistance to utilize antibiotics that battle with bacteria properly.
The experimentation of animals was the only time a physician could “…achieve true medical science’ (Source Book 2, p.68) remarked physiologist Claude Bernard in an 1865 essay. Even though Pasteur researched rare diseases such as anthrax he paved the way for physicians such as Robert Koch who discovered the bacteria of tuberculosis which in this period was a major killer of the period. These discoveries lead to tests of tuberculosis vaccine therapies and allowing treatment of the disease. The creation of these vaccines to aid the practice of physicians was greatly ameliorated by the study of microorganisms causing... ... middle of paper ... ...y in Europe 1800-1930: A Source Book, Manchester: Manchester University Press, extract 4.4, pp.81-85 • Brunton, D.

The introduction of genes, white blood cells, blood groups, insulin, rubber gloves, aspirin, and vitamins and the discoveries of Pasteur, Charcot, Halsted, Zirm, Lister, and Koch were the starting point of an international fight against disease. A remarkable breakthrough in medicine occurred in the late 1800s through the work of Louis Pasteur. Pasteur's experiments showed that bacteria reproduce like other living things and travel from place to place. Using the results of his findings, he developed pasteurization, which is the process of heating liquids to kill bacteria and prevent fermentation. He also produced an anthrax vaccine as well as a way to weaken the rabies virus.
Antibiotics have always been some of the key contributing factors in the medicinal industry. An example of past antibiotics that greatly contributed to medicine is Penicillin. Penicillin was created in the late 1920s and received widespread clinical use during World War II by helping soldiers who were wounded and risked infection, because of its properties that prevent the creation of peptidoglycan in gram-positive bacteria. However, the older forms of Penicillin have been rendered completely useless because of the rapid evolution of bacteria to resist Penicillin. This has created an eternal race regarding whether people can develop the antibiotics to defeat resistant bacteria fast enough (McDonald, 2013).
Almost a decade later, in 1939, Ernst Chain and Howard Florey were able to develop a way to isolate penicillin and used it to treat bacterial infections during World War II. This new drug came was made available for clinical circulation in 1944 and huge impact was made on public health. For these explorations Fleming, Chain and Florey were presented with the Nobel Prize for Medicine in 1945. Their findings and development transformed modern medicine and paved the way for the advancement of many more natural antibiotics. While Fleming was working on penicillin, Gerhard Domagk, a German doctor, revealed the discovery of an artificial molecule with antibacterial components.
Consumption pick of anitibiotics started with discovery of Penicillin which played significant role in the pharmaceutics. According to American Chemical Society (2004) the one of the greatest discoveries is the discovery of the Penicillin. Before the existence of antibiotics people were dying in the hospitals just from the pathogenic bacteria in their wounds. The history of using Penicillin as a medication begins in ancient times when Egyptians were putting bread with molds on bleeding wounds. However, it is assumed that the discovery of the penicillin as antibiotic belongs to Alexander Fleming in 1928.
He detected that a substance he called "penicillin" destroyed bacteria. Then in the late 1930's, two British scientists invented a method of extracting penicillin from the mold. This was the start of developing new drugs to treat diseases and bacteria. Over the years, numerous thousands of antibiotic material have been found in nature as well as produced chemically but, there are few that are safe and useful. However the ones that are safe and effective have saved many lives and have helped extend life expectancy.
in Youngson 70). Chloroform also did not need an inhaling device like ether did; it could be placed on a piece of cloth and work just as well (Youngson 70). Antiseptics One of the leading surgeons of the time was also the first surgeon to use antiseptics in surgery. Joseph Lister believed that infections were a result of bacteria. He used various methods to fight the bacteria, constantly changing his methods over the years.
After its initial discovery, Penicillin was purified and manipulated into a form that could be used to cure bacterial infections (Aldridge, Parascandola,and Sturchio 4). Penicillin is one of the greatest medical discoveries during the twentieth century, but it wasn’t ready to use the day after it was discovered, in fact, it took years before clinical use and before it was successfully mass produced. The first step towards mass production was gaining the support of the public. World War 2 allowed penicillin to gain popularity because of its impact on the allied forces. Because of the widespread use in the war and because of production rate, the price of penicillin dropped from 20$ per vial to one dollar per vial (Hamblin 240).
