Penicillin is a rare type of mold that kills bacteria. The discovery of penicillin was made by a scientist named Alexander Fleming. Penicillin was actually discovered by accident when Alexander Fleming left his house for vacation and when he came back he found that there was mold on his dishes and he immediately examined the mold. Fleming was credited with the discovery of penicillin, Florey was credited with making it into a medicine, and Morey was credited with the mass production of penicillin. Most of the development of penicillin happened in the 1900’s but the discovery of penicillin was in 1890.
The discovery of penicillin was a game changer because it kills bacteria and it quite easy to make. Fleming was a very smart and skilled scientist,
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.

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
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. After studying Pasteur's work, Joseph Lister developed antisepsis, which is the process of killing disease-causing germs.
Most of these medical advances were a result and were an influence of World War I. Probably one of the most important medical advances was the discovery of penicillin in 1928 by a Scottish, microbiologist named Alexander Fleming, he had actually accidently discovered it, when he noticed that a bacteria culture he had been growing, had stopped, he realized that it had been contaminated by a rare form of mold called Penicillin and that it had killed the bacteria.
My disease is Streptococcal pneumonia or pneumonia is caused by the pathogen Streptococcus pneumoniae. Streptococcus pneumoniae is present in human’s normal flora, which normally doesn’t cause any problems or diseases. Sometimes though when the numbers get too low it can cause diseases or upper respiratory tract problems or infections (Todar, 2008-2012). Pneumonia caused by this pathogen has four stages. The first one is where the lungs fill with fluid. The second stage causes neutrophils and red blood cells to come to the area which are attracted by the pathogen. The third stage has the neutrophils stuffed into the alveoli in the lungs causing little bacteria to be left over. The fourth stage of this disease the remaining residue in the lungs are take out by the macrophages. Aside from these steps pneumonia follows, if the disease should persist further, it can get into the blood causing a systemic reaction resulting in the whole body being affected (Ballough). Some signs and symptoms of this disease are, “fever, malaise, cough, pleuritic chest pain, purulent or blood-tinged sputum” (Henry, 2013). Streptococcal pneumonia is spread through person-to-person contact through aerosol droplets affecting the respiratory tract causing it to get into the human body (Henry, 2013).
Stewart, Philip S, (2001) states that antibiotics are elements that are used to kill, or hinder the multiplication and growth of organisms. Especially, these antibiotics are meant to control fungi and bacteria. In this case, the antibiotics that are used in killing bacteria are referred to as bactericidal, and the ones that are used to prevent the multiplication process are bacteriostatic. The primary microbes for antibiotics are bacteria and fungi. These microorganisms are crucial to facilitate the secretion of substances that kill harmful bacteria which confer competition for the limited available nutrients (Southern, P. J., &Berg, 1981).
The decade between 1920 and 1930 was a milestone for many health breakthroughs. The work that was done in the 1920’s had a major impact in increasing overall life expectancy. Penicillin and insulin are an easy fix for sore throats and diabetes, respectively.
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
, prevention and control in our hospitals, have left South Africa, like the rest of the international community, on the brink of a return to an era of stubbornly resistant pathogenic bacteria towards antibiotics.
Name: Date: Section: Survival and Community Dynamics in 'Dawn of the Dead (2004) through Macmillan and Chavis Perspective In the midst of a zombie apocalypse, the notion of community takes on paramount significance, offering a lifeline amidst the chaos and uncertainty. " Dawn of the Dead (2004)" thrusts audiences into a harrowing tale of survival, set within the confines of a shopping mall besieged by the undead. This film serves as a compelling canvas through which to explore the intricacies of human relationships and societal collapse.
Ampicillin disrupts the third and final stage of bacterial cell wall synthesis by binding specific penicillin-binding proteins (PBPs) that are inside the bacterial cell wall. Then facilitated by bacterial cell wall autolytic enzymes, cell lysis beings. Ampicillin is metabolized by Hydrolysis of the B-lactam ring to penicilloic acid. Microorganisms such as salmonella, Escherichia coli, campylobacter, shigella aquificae, thermotogae, chrysiogenetes, nitrospira, deferribacteres, other eubacteria, and other enteric bacteria are sensitive to Ampicillin. Treatment Dosage can range from 1 to 2g IM or IV every 4 to 6 hours to the maximum does of 12g per day. Microorganisms resistant to Ampicillin are penicillinase- producing bacteria (some strains of staphylococci), Pseudomonas aeruginosa, P. Vulgaris, Kiebsiella pneumonia, and Enerobacter aerogenes.
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
Sir Alexander Fleming changed the world of medicine not only in his days but also in the world today. We have the medicines and antibiotics that we have today because of Alexander Fleming. His discovery was much needed in the world and I hate to think where we would be in the medicine world if he hadn’t discovered penicillin.
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.
