The Evolution Of Penicillin

Acacia Dairsow Page one P.5 The Amazing Discovery of Penicillin and Antibiotics! Antibiotics have been around for years, but at the same time only for a short period, as in about 80 years ago Therefore penicillin and antibiotics are one of the greatest discoveries of the 20th century Seeing as how Penicillin is one of the greatest discoveries of the 20th century, it is now commonly used to cure “common” or “simple” infections, Alexander Fleming was the one to discover Penicillin and its uses, and Penicillin was actually discovered by accident. I’ve used a variety of sources to learn and study about one

The development of antibiotics was an important advancement in 20th century medicine. Previously deadly infectious diseases are now routinely treated with antibiotics. Moreover, for modern-day medical procedures such as chemotherapy treatment to be successful, antibiotic use is necessary. For these reasons, the prospect of bacteria developing widespread resistance to antibiotics is a major concern as it would render many modern-day medical therapies unviable.

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

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

Antibiotics are inarguably one of the greatest advances in medical science of the past century. Although the first natural antibiotic Penicillin was not discovered until 1928 by Scottish biologist Alexander Flemming, evidence exists that certain plant and mold growths were used to treat infections in ancient Egypt, ancient India, and classical Greece (Forrest, 1982). In our modern world with the advent of synthetic chemistry synthetic antibiotics like Erithromycin and its derivative Azithromycin have been developed. Antibiotics have many uses including the treatment of bacterial and protozoan infection, in surgical operations and prophylactically to prevent the development of an infection. Through these applications, antibiotics have saved countless lives across the world and radically altered the field of medicine. Though a wonderful and potentially lifesaving tool, antibiotic use is not without its disadvantages. Mankind has perhaps been too lax in regulation and too liberal in application of antibiotics and growing antibiotic resistance is the price we must now pay. A recent study showed that perhaps 70% of bacterial infections acquired during hospital visits in the United States are resistant to at least one class of antibiotic (Leeb, 2004). Bacteria are not helpless and their genetic capabilities have allowed them to take advantage of society’s overuse of antibiotics, allowing them to develop

A Superbug is a bacterium that can live in the human body and has the ability to withstand all forms of antibiotic medication. Superbugs are becoming increasingly significant in modern medicine as they are becoming more and more resistant to antibiotics. Antibiotics were discovered in 1928 by Alexander Fleming (Walsh and McManus, 2000). This resulted in a huge movement forward in medical history and even greatened human life expectancy. Since then antibiotics have been widely used and abused, people began to treat everything with this ‘miracle’ drug. If antibiotics are continually used as bacteria grows exponentially more resistant to them then eventually society will fall back into an era without the readily

The article “The End of Antibiotics” discusses a 57 year old man that was dying and how doctors could only sit by while his condition deteriorated. This man was not shot or stabbed, he was infected with antibiotic resistant bacteria that was slowly killing him. He died months later after being bombarded with antibiotics in the form of capsules, tablets, and IVs (Begley par.1). This is the unsettling power that superbugs like this one has over modern day medicine. A superbug is a bacteria that has evolved its cellular structure to resist antibiotics. Dr. Richard Wenzel of the University of Iowa stated, “Only a few years after penicillin came into wide use with World War II, strains of staph had emerged

(Centers for Disease Control and Prevention, 17 April 2015, para. 7). If your doctor has ever given, or will give you antibiotics, the misuse, the wrong dosage, and even the wrongful prescription of antibiotics, such as for a virus, can eventually contribute to making a superbug, again according to the CDC (Centers for Disease Control and Prevention, 1 February 2017, para. 2-5). There are already many instances of superbugs taking people’s lives. For example, just this January 2017, the CDC reported that a Washoe County resident in Reno, Nevada died in late September 2016 because she had an infection from a superbug that could not be cured by every available antibiotic in the United States (Centers for Disease Control and Prevention, 1 August 2017, para. 1-5). Posted on the Infectious Diseases Society of America website in 2007 by her mother was the story of how Rebecca Lohsen, a 17-year-old high school student and swimmer from New Jersey, died from an MRSA infection, an infection resulting from a superbug (Infectious Diseases Society of America, September 2007, para. 1). On that same website, posted by her parents, a 19-year-old college student, Meredith LittleJohn, died to a superbug after spending time in an intensive care unit in a hospital (Infectious Diseases Society of America, n.d., para. 1-3). And the list of those affected goes way on. So as we can see, superbugs are definitely a threatening and real issue that can affect almost anyone.

The world health organisation has announced antibiotic resistance and the rise of superbugs as a great threat to human race. Superbugs are defined as bacteria equipped bacteria with "bullet proof vests” of antibiotic resistance that deflect "magic silver bullets" of antibiotics. Under right circumstances, they can transfer the antibiotic resistance genes to other bacteria and completely paralyse humans to combat against bacteria (news.com.au 2014). In Australia, thousands of people per year are diagnosed with superbugs and these victims often face a prolonged illness and ultimately death (Pogson 2012). The severity of the problem can become apparent by referring to the death attributable to antibiotic resistance every year from 2014 to 2050,

A current predicament in the field of science is antibiotic resistance against superbugs.Though fighting against superbugs; which can be defined as a strain of bacteria unable to be killed using multiple antibiotics, is now a large problem, in the past it was not. The evolution of resistance in bacteria due to antibiotic abuse and lack of product development has brought upon us once again the fear of a pre-antibiotic era; one where simple, once easily defeated infections could kill. Already, infectious diseases are the 3rd leading cause of death in the US and the 2nd across the entire world, and drug resistant superbugs send 2 million Americans to hospitals every year; killing 23,000 of those people. And any bacterium can quickly and easily become multidrug resistant, the leading cause of this being antibiotic misuse in both humans and animals.( "Clinical Infectious Diseases." The Epidemic of Antibiotic-Resistant Infections: A Call to Action for the Medical Community from the Infectious Diseases Society of America. UCLA Medical School. Web. 27 Mar. 2016.)

Penicillin is a widely used medicine that has effectively shaped the world. Millions of people would have not made it through their sicknesses if it weren’t for this spectacular discovery. Penicillin was actually discovered on accident, further researched before and during the war, and mass production to the public. Penicillin was one of the best accidents in the world.How penicillin came to be a widely used medicine around the world is a mystery we will soon find the answer to.

Widespread use of antibiotics has been very controversial in the media as well in the general population. Due to these controversies, it is very misunderstood to how antibiotics work leading to many patients in the hospital setting wanting to take them when it is not necessary or refusing to take when it is necessary for their survival. Some of this controversy is due to antibiotic resistance, which has spread an alarming rate in the 21st century (Walsh, 2000). Antibiotic resistance is the result of very strong bacteria or microbes that are resistant to the antibiotic prescribed and those microbes accumulate overtime by their survival, reproduction and transfer, leading to increased levels of antibiotic resistance.

Since antibiotics, such as penicillin, became widely available in the 1940s, they have been called miracle drugs. They have been able to eliminate bacteria without significantly harming the other cells of the host. Now with each passing year, bacteria that are immune to antibiotics have become more and more common. This turn of events presents us with an alarming problem. Strains of bacteria that are resistant to all prescribed antibiotics are beginning to appear. As a result, diseases such as tuberculosis and penicillin-resistant gonorrhea are reemerging on a worldwide scale (1).

The overuse of antibiotics has been a problem for well over a decade. This misuse leads to many nonvisible problems arising within the human population. As the use of antibiotics increases, the number of antibiotic resistant bacteria also increases. When bacteria become resistant to an antibiotic, another antibiotic must be used to try and kill it and the cycle becomes vicious. Michael Martin, Sapna Thottathil, and Thomas Newman stated that antimicrobial resistance is, “an increasingly serious threat to global public health that requires action across all government sectors and society” (2409).
