Penicillin Essays

inhibiting bacterial protein synthesis, and inhibiting bacterial DNA replication. This also brought us to the discussion of the first antibiotic to be manufactured against illness-induced bacteria during World War II which was Penicillin. The discovery of the antibiotic Penicillin was by the British Bacteriologist Sir Alexander Fleming in 1928. This led me to my essential question for this particular research paper which is to figure

Research question: In this experiment we will use 6 different antibiotics which are Mezlocillin,Cefazolin,Lincomycin,Penicillin,Erythromycin,and Oxacillin on these two bacteria that is Bacillus subtilis and Micrococcus luteus and see the result which antibiotic will work better on which bacteria. We will put the bacteria on agar-agar plate with the antibiotic and leave plate for a week to get the result how effectively the antibiotic have work on the bacteria. Background on antibiotic: Bacillus

The Spores That Changed the World “The discovery of penicillin not only revolutionized medicine, but changed the world” (“Penicillin”). Penicillin was the first in a class of drugs called antibiotics. The introduction of penicillin ended centuries of failure to cure infections (“Penicillin”). Alexander Fleming is, amongst others, the most notable founder of penicillin. During his summer vacation, Fleming went to his trial lab at Saint Mary’s Hospital to check on some of his ongoing projects

Penicillin is an antibiotic which is made from the mould from Penicillium. Penicillium is a fungi which is found naturally in soils, wood, plants etc. (Frisvad & Samson, 2004). During the early 20th century a scientist by the name of Alexander Fleming discovered the effects of the Penicillin. (Dougherty & Pucci, 2011) Fleming discovered this effect by luck, he went away for a holiday and when you came back he saw some petri dishes he had left which contained Staphylococcus. Fleming saw that Penicillin

Penicillin was a groundbreaking discovery and saved many lives, and also helped with future medical discoveries. In 1928, a scientist named Alexander Fleming discovered Penicillin. It was used a great deal as an antibiotic in World War II, it saved countless lives and improved medical work in the early 20th century. Penicillin is any group of chemically similar substances obtained from molds of the genus Penicillium, a drug used to fight bacteria and infections. (J. D. Hamblin, 2005). This drug was

it. It was Penicillin. Penicillin left an imprint in our history, it expanded medicinal innovation, manufacturing and even diminished diseases. it increased medical technology, manufacturing and even decreased infections. The utilization of penicillin in WW2 incredibly influenced the Allied soldiers positively. Penicillin was significantly required on the front lines of World War 2 to treat harmed troops. (Krebs,20) The infection death rate of the Allies vanished amid WW2 when penicillin

The greatest hero of World War II may come as a surprise. Penicillin is responsible for saving hundreds of thousands of lives from infectious diseases during the war. Penicillin took a while to become a widely used medicine, but its effects were revolutionary. To lead off, the first discovery of penicillin was made by Alexander Fleming. This monumental discovery happened to have been found and created by accident. After returning from a month long vacation, Fleming noticed something in one of

can have dosage forms changed quickly i.e. how the drug is delivered. For example, tablet or capsule form. 6.2.1 and 6.2.2 Penicillin An antibiotic in the penicillin group of drugs helps fight bacteria in the body. It is used to treat various types of bacterial infections such as ear infections. Penicillin works by preventing bacteria from forming new cell walls. Penicillin was first discovered accidently in 1928 by a Scottish scientist named

getter: • Good morning to everyone. • Does anyone know what penicillin is? I bet everyone know it and some even use it before. But, let me ask you, do you know who discovered penicillin? Well, the penicillin is discovered by my favourite innovator, Sir Alexander Fleming. 2. Introduction: • Profile/bio data/background of the innovator o Sir Alexander Fleming was famous as a Biologist and Pharmacologist. Fleming was the one who discovered Penicillin, a type of antibiotics. He was born on 6 August 1881 at

INTRODUCTION: In this experiment I was testing for antimicrobial sensitivity of Staphylococcus epidermidis by using the Kirby-Bauer Diffusion test. The three antibiotics utilized in this lab were: gentamicin, novobiocin, and penicillin. I determined the effectiveness of the antibiotic by observing and measuring the zone of inhibition for each antibiotic. I used the measurements and compared them again with the Antibiotic Susceptibility zone chart. I was able to determine whether the S. epidermidis

Flucloxacillin: - It is a member of the penicillin family that is used as an antibiotic for the staphylococcal infection (bacterial infection) that affects the human tissues of the skin and the lungs (pneumonia). It is also used in the treatment of food (rotten food) and poisoning of theblood. Staphylococcus may also be a risk to the human life if it releases its toxins by some strains of the bacteria to cause toxic shock. - Flucloxacillin is prescribed mainly in Australia & Europe, as it is very

Third Generation Cephalosporin Cephalosporins are antimicrobial drugs that were first discovered in 1945 by Giuseppe Brotzu. Brotzu was a University of Cagliari professor and a Sardinia government official who worked to eradicate malaria. It was found that cultures of fungi called Cephalosporium acremonium, which came from sewage water, could inhibit the growth of other bacteria. Since then, many cephalosporin drugs have been formulated, among them the third generation cephalosporin, which has a

When species encounter each other in an environment, competition over things such as space and resources is very likely to occur. Unlike the more well-known hierarchal competition, intransitive competition occurs between organisms that cannot be ordered from most to least competitive. An example of this type of competition is the game rock-paper-scissors. Rock beats scissors, scissors beat paper, and paper beats rock. When any two of the competitors face off, one outcompetes the other. However

outside of the intestinal tract. The host can be effected by the consumption of contaminated water or food, or having contact with the animals or people. Penicillin, is the first antibiotic that is medically used to fight off a large range of bacterial infection. For this experiment, we will be using ampicillin, it is a part of the penicillin drug group. The ampicillin inhibits the bacteria with the result of killing the bacterium or prevents it from multiplying. “When a bacterium multiplies, small

Methicillin Resistant Staphylococcus Aureus Methicillin Resistant Staphylococcus Aureus (MRSA) is a bacteria resistant to all antibiotics containing penicillin. MRSA otherwise known as a superbug has been produced through the process of natural selection inside hospitals, which provide the perfect environment for this bacteria to thrive in. Bacteria like MRSA are hard to treat as there are fewer antibiotics to treat it therefore increasing its deadliness. The antimicrobial resistance in MRSA is genetically

Chemical structure Linezolid is the first member of the group Oxazolidinone antibiotics. Oxazolidinones (sulfoxide 1) were first characterized for their use in treating plant diseases in 1978. Six years later antibacterial properties were discovered, with greatly improved antibacterial properties relative to their progenitor compounds. It is usually these two compounds, which are referred to as the first true lead compounds in the oxazolidinone family (lead compound - compound that exhibits pharmacological

antibiotic, penicillin, was discovered in 1928 by Alexander Fleming. Although it was not distributed among the general public until 1945, it was widely used in World War II for surgical and wound infections among the Allied Forces. Fleming’s antibiotic discovery was hailed as a “miracle drug” that opened the door to a world where infectious diseases were virtually non-existent. Although Fleming’s discovery won him the Nobel Prize, he warned of bacteria becoming resistant to penicillin in his acceptance

1.) Methicillin Resistant Staphylococcus Aureus (MRSA) is a gram-positive bacterium that is resistant to beta-lactam antibiotics such as Penicillin and Methicillin. CA-MRSA or Community Acquired Methicillin Resistant Staphylococcus is found in the community and not associated with hospitals. This strain can potentially cause disease in healthy individuals by its infamous toxin, Panton-Valentine Leukocidin which causes necrosis of alveoli. CA-MRSA is commonly found among military recruits, athletic

‘magic bullet’, or chemotherapy, to designate the use of antimicrobial compounds to treat microbial infections. In 1910, Ehrlich discovered the first antibiotic drug, Salvarsan, which was used to treat Syphilis. Later Alexander Fleming, discovered Penicillin in 1928. Then, in 1935, Gerhard Domagk discovered the sulfa drugs, that paving the way to the discovery of the anti-TB drug Isoniazid. Then, in 1939, René Dubos became the first scientist to discover an antibiotic after deliberately looking for
