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. (Ramanan Laxminarayan, 2013)
The emergence of Penicillin marked the dawn of the antibiotic era and allowed for diseases which normally ended in death or dysfunction to be eliminated and for people to carry on living healthy lives. It is estimated that 90% of children who had meningitis of the bacterial kind in the pre-antibiotic era would either die or survive the illness with a physical impairment. Strep throat, whooping cough, tuberculosis and pneumonia are among some of the other fatal bacterial diseases which would usually result in a fatality. Antibiotics decreased the mortality rates, and so new antibiotics were formed.
At his Nobel Peace Prize speech in 1945, Alexander Fleming warned against the misuse of antibiotics and the fact that by doing this, one allows the bacteria to ‘become educated’ and therefore become resistant to the antibiotic. It is believed that the first cases of antibiotic resistance were shortly after this speech. (Fleming, 1945)
There are many medical professionals who believe that the rise of antibiotic resistance is a result of the overuse and misuse of antibiotics. Dr. Jim Wilde, a paediatric emergency medicine physician at the Medical College of Georgia believes that the medical profession is losing the war against resistance...

...gests that the world is on the brink of a post-antibiotic era as the numbers of resistant bacteria (superbugs) proliferate, and there is an increase in the number of people dying from previously treatable infections. Todar, (n.d) states, “Society could be faced with previously treatable diseases that have become again untreatable, as in the days before antibiotics were developed.”
Medical science and pharmaceutical researchers need to vigorously investigate the many factors contributing to the decline in antibiotic efficacy which will then empower them to research and develop a new generation of antibiotic therapies. Aligned with this is the responsibility of each individual to manage their health and expectations with regard to treatment. For example, individuals could adopt better ways of maintaining their immune systems by means of a healthy diet and exercise.
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
In the last decade, the number of prescriptions for antibiotics has increases. Even though, antibiotics are helpful, an excess amount of antibiotics can be dangerous. Quite often antibiotics are wrongly prescribed to cure viruses when they are meant to target bacteria. Antibiotics are a type of medicine that is prone to kill microorganisms, or bacteria. By examining the PBS documentary Hunting the Nightmare Bacteria and the article “U.S. government taps GlaxoSmithKline for New Antibiotics” by Ben Hirschler as well as a few other articles can help depict the problem that is of doctors prescribing antibiotics wrongly or excessively, which can led to becoming harmful to the body.
Resistance arises from mutations that are not under the control of humans, but the evolution of bacteria has been sped along by the overexposure of antibiotics to both people and animals. The number of antibiotic-resistant strains of bacteria in an area is closely related to the frequency that antibiotics that are prescribed (Todar, 2012). Patients often unnecessarily demand antibiotics to treat common colds or simple illnesses that are not caused by bacteria. Instead, these infections are caused by viruses which, unlike bacteria, are unaffected by antibiotics. Incorrect diagnosis can also lead patients to using unnecessary antibiotics, which can sometimes be even more dangerous than otherwise left untreated. Besides the fact that antibiotics kill off beneficial bacteria in the intestines, misuse of antibiotics provides an opportunity ...
Medical procedures and inventions are constantly being developed and made better. World War 1 was a time in which many of the procedures used today were first thought of and used. It was a time that inspired the doctors and nurses working today, not to mention the fact that it’s a topic that still affects everyone in the world today. Medical advancements made during World War 1 had a major impact on the world as evidenced by those advancements still in use today.
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.
According to USA Today, U.S. doctors are prescribing enough antibiotics to give to 4 out of 5 Americans every year, an alarming pace that suggests they are being excruciatingly overused. In fact, Dr. Aunna Pourang from MD states, “to give you an idea of how high the pressure is to prescribe antibiotics, I didn’t get a job once because during the interview I told the lead physician that I only prescribe antibiotic prescriptions when they are warranted.” The development and widespread obsession of antibiotics, or drugs that kill bacteria and thereby reduce infection, has helped billions of people live longer, healthier lives. Unfortunately, the more we rely on and abuse antibiotics, the more bacteria develop resistance to them, which makes treating infections that much more challenging and leads to the growth of drug-resistant strains of bacteria. Research from the Center of Disease Control found that two million people in the United States become infected with antibiotic resistant bacteria, while 23,000 people die from such infections each year. Americans often aren’t informed on the power of the human body and rush to assumptions when perfection isn’t present. In a nutshell, the obsession of antibiotics is quite deadly and needs to be addressed before it’s too
Carroll. Even with widespread controversy over antibiotic resistance, Carroll remained neutral with his writing, pointing out facts that fit both sides of the argument. One of the most important issues addressed in the article was the lack of education when it comes to the proper use of antibiotics. The health of the public would benefit greatly from education about viruses and bacterial infections. Carroll’s article is a good resource for the basis of the topic’s education. The article informs readers about the importance of antibiotics and the development of antibiotic resistance as well as future prevention and research for antibiotic
Penicillin, the first antibiotic, was discovered accidentally by Sir Alexander Fleming in 1928. Sir Fleming was growing bacteria on agar plates and accidentally left one of the plates open. A mould started growing on this. Fleming noticed that no bacteria grew
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
“The World Health Organization projects that as drug effectiveness decreases and antibiotic resistance increases, public education becomes more and more crucial” (476) Antibiotics were discovered in 1940 and since have been abused and misused. Between bad practices and lack of proper education antibiotic resistance has been allowed to occur. The only way to combat bacterial infections is with strong patient education and following the correct schedule in taking antibiotics.
. Many doctors and patients are unaware that antibiotics are designed to treat bacterial infections, not viral infections (Antibiotic resistance, N.D.). Many bacteria within our bodies are not harmful at all, and some of them actually provide health benefits. The bacteria that are harmful are disease-causing bacteria, which generate sicknesses such as strep throat, the common cold, and ear infections (Get, 2013). Viruses are smaller than bacteria and require hosts, such as plants or animals, in order to proliferate (What, N.D.). Doctors play a vital role in administering antibiotics, for patients rely on their knowledge and expertise in order to receive proper medication for ailments throughout their lives. According to www.acponline.org, 190 million doses of antibiotics are administered every day. Among patients that do not reside in hospitals, doctors prescribe more than 133 million antibiotic programs every year. Of those 133 million programs, it is estimated that over 50 percent of them are unnecessarily prescribed because the doctor is prescribing them for viral infections such as common colds or simple coughs (Antibiotic resistance, N.D.). However, doctors are not the only ones to blame in regard to misuse of antibiotics because their patients are just as guilty when it comes to ignorance in respect to antibiotic usage. Many preventable factors have emerged because of irresponsibility of patients, including self-medication practices and the temptations of cheap, counterfeit drugs, all of which have aggravated drug resistance in the last 20 years (What, N.D.). Also, many patients are unaware of the dangers that can result from leaving medication behind because they don’t use it. It is extremely ill-advised to leave behind eve...

Thesis: With the advent of antibiotics in 1929 Fleming said, "The time may come when penicillin can be bought by anyone in the shops.Then there is the danger that the ignorant man may easily underdose himself and by exposing his microbes to non-lethal quantities of the drug make them resistant."With the overuse of antibiotics today we have seen this very idea come to be.Over usage is caused most prevalently by a lack of education on the part of the patient.Thus stated, the way to overcome such a circumstance is to educate, not only the patient but also the physician.

Antibiotics is one of the most effective weapons that the human race has against bacterial infections, as antibiotic treatments can clear an infection within a three to eight day period. However, the constant use of antibiotics has allowed bacteria to mutate their DNA, making them more resistant against the drug. Many scientist theorize that this resistance pattern will lead to a superbug, a bacterium strain that is resistant to possibly all antibiotics. That kind of disease could be catastrophic and lead to a decline in population and progression. The growing issue of mutation made the idea of restricting medicine more favorable, but regulations against antibiotics could be a huge mistake. Many different companies relies on the leniency to
