Antibiotics have been vital tools in the fight against bacterial infections, however their effectiveness has waned in recent times due to the advent of antibiotic resistant strains of bacteria. According to a review by P, the uses of antibiotics, as well as influences from the environment have allowed such bacterial strains to respond to changes in their environment rapidly, and so develop resistance. This acquired ability can have serious and broad implications in the medical field, evident in a study by O into the resistance of intestinal Staphylococcus aureus.
It has been suggested that bacterial resistance develops with unnecessary over-prescription, and early termination of antibiotic treatment. O noted that unsupervised self-medication of antibiotics was a key factor in the advancement of antibiotic-resistant bacteria. A recent study revealed alarming use of antibiotics within the developing world. Non-prescription antibiotics have been primarily used to treat cough and influenza, where patients cease medication themselves prior to completion of the course because they fel...
The painkiller Vioxx was introduced in 1999 by Merck & Co. It has been used by over 20 million Americans since it was put on the market. Vioxx remained on the market for approximately five years without adequate warnings about its risks. In September of 2004, Merck took Vioxx off the market after a study revealed that it doubled the risk of heart attack or stroke for patients that used it for more than 18 months. Although Merck claimed that they had no idea of these possibly lethal side effects, some internal documents imply that they had been aware of the problem for years and had not made moves to change it. Over 300 lawsuits have been filed against Merck, and it is expected that thousands more will arise.
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
The first theory, and the theory backed significantly by scientific data, suggests that when a patient receives antibiotics, they are more likely to acquire MRSA than someone who has not taken the antibiotic. These occurrences increase when the patient does not complete the antibiotic prescription given to them by the doctor. This suggests that when you do not finish the antibiotic course, there is a chance that you will kill most of the bacteria, but not all of them, and the ones that survive are likely to be those that are most resistant to antibiotics [paper 1]. The second theory surfaced in 2014 and presents evidence for an unexpected route to the evolution of antibiotic resistance in staphylococcal communities that occurs without natural selection due to antibiotic treatment. It suggests that the bacteria gains resistance solely via intraclonal competitive interactions between bacterial cells [paper 5]. This review will further analyze these hypotheses and the strengths they each
Penicillin is the reason people lived healthy and long lives. Sick, cold, and sore, are feelings people have when they are sick. If people were to become sick and penicillin was not around they would have those feelings for a longer duration. Penicillin was an idea that belonged to a famous scientist by the name of Sir Alexander Fleming. Penicillin was just the slightest of idea in Fleming’s mind after he married his wife who had the profession of a nurse. Fleming made penicillin after conducting test on accidentally infected fungus inhabited plates. He tried washing the fungus of with disinfectant, then he noticed a yellow-green zone around the fungus. He came up with the conclusion that penicillin’s main goal would be to eliminate the outer weak ring
“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.
Antibiotic resistance is a consequence of the misuse of antibiotics that give pathogenic bacteria the ability to withstand the effects of an antibiotic. Resistance occurs when bacteria change in such a way that they survive exposure to antibiotics. Resistance may not be confined to a single antibiotic, but may affect multiple antimicrobial classes. Antibiotic resistance is a major problem and everyone needs to work together to combat it - from medical practitioners to patients.
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 ...
The controversy regarding the sub-therapeutic use of antibiotics in animal feeds is that “super-bugs” are able to evolve. This is a threat to both the health of the animals and humans. What a “super-bug” refers to is a strain of bacteria that has evolved to be resistant to bacteria and lethal to the host organism. These super-bugs account for the death of roughly 48,000 Americans each year (Adams, 2013). These superbugs proliferate in the digestive tracts of hosts. Each dose of antibiotics in the animals’ diets at sub-therapeutic levels increases the likelihood of antibiotic resistance bacteria to evolve. The antibiotics kill the antibiotic sensitive bacteria, but bacteria that are resistant proliferate in the gut of the animals. When these antibiotic resistant bacteria are left to grow in the gut, they can cause infection to the animal or people that consume the animal as food (Falco, 2013, Amachawadl et. al. 2013). Antibiotic-resistance can also be conferred through horizontal gene transfer and other methods, making the mere existence of such bacteria a threat that should not be taken lightly.
Over the years humans have tried every possibility to overcome the health problems, spread of epidemics and infections, disease control and have worked towards a healthy society free of disease and health problems. They have succeeded to a great extent. The book “Good germs, bad germs” describes that though the life expectancy is now far more as it was in previous eras. Epidemic problems and infectious diseases are now getting lesser and lesser and humans are being treated successfully. The hygienic conditions have also been improved so as to ensure least growth of microbes, germs, parasites and bacteria. Antibiotics have been invented to address diseases and infections caused by bacteria and viruses. With all these substantial efforts the biologists, physicians and scientists have triggered another epidemic which is even more severe. They have killed those microbes and bacterial species which were human friendly and as a result of either their disruption or mutation, pathogenic bacteria have even become more active and resistant to treatments. This has led to increased ineffectiveness of antibiotic drugs, low immunity and various infections and inflammatory diseases. The chlorinated water for drinking and food processing along with excessive hygienic conditions indicates our fight against these bacteria and germs. Further, these antibiotics are even given to the livestock which becomes our food and as result many of their resistant germs end up in our digestive tract and other organs. Thus, the war against microbes through excessive cleanliness and use of antibiotics has resulted in antibiotic resistance among humans, which has become one of the prominent problems of medical science
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.

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.
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...
Exposure to antimicrobials fundamentally alters microbial ecosystems of humans, animals and the environment, which may lead to the development of antimicrobial resistance.
The most effective way to combat pathogenic bacteria which invade the body is the use of antibiotics. Overexposure to antibiotics can easily lead to resistant strains of bacteria. Resistance is dangerous because bacteria can easily spread from person to person. Simple methods for preventing excessive bacterial spread are often overlooked. Not all preventative measures are even adequate. Doctors and patients often use antibiotics unnecessarily or incorrectly, leading to greater resistance. Antibiotics are used heavily in livestock and this excessive antibiotic use can create resistant bacteria and transfer them to humans. In order to reduce resistant bacteria,
