Antimicrobial Drugs And Antibacterial Drugs Essay

The outlook on antibiotics has changed dermadicly since we have fist started using them. Antibiotics is a substance that is produced by a microorganism that can kill or prevent the growth of another microorganism. The major conflict that will be covered in the paper is antibiotic resistance. Antibiotics resistance

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.

Antibiotics, composed of microorganisms such as streptomycin and penicillin, kill other infectious microorganisms in the human body. At one point, antibiotics were considered to have “basically wiped out infection in the United States”, but due to their overuse and evolutionary

Fleming in 1928. Penicillin helped to treat some common infections: step throat, boils, it would heal wounds quicker, as well as treat more serious infections such as meningitis and pneumonia. Antibiotics usually kill only weak bacteria and after some years of antibiotic usage stronger bacteria have not only survived but also became resistant to the old cure. “Doctors have started to prescribe antibiotics to cure conditions such as ear infections, sinusitis, bronchitis, non-specific upper respiratory tract infections and even common colds and flu… According to the Director of Antimicrobial Resistance, Dr. Richard Besser, each year US physicians write $50 million worth of prescriptions that are ineffectual and unnecessary.” (Elisa Bussey). The more doctors were prescribing antibiotics, the bigger the number of people who become resistant to them. Most of the European countries prescribe antibiotics to kill bacteria only in cases of life threatening conditions. Patients in the US have become accustomed to receiving antibiotics for almost any health concerns and with time, patients have started to expect such prescriptions as a norm.

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

Since the introduction of penicillin to the public in 1942, antibiotics have gained widespread use throughout the world. The drug has allowed society to make advancements in medicine, increase an individual’s personal well-being, extend life expectancies, and stop and prevent infections. Antibiotics are one of the largest backbones to maintaining personal health in society today, yet there may be a day when we are no longer able to depend on antibiotics to fight infections. In the essay “Imagining the post antibiotic future”, Maryn McKenna establishes the importance of antibiotics to juxtapose how devastating life would be without them.

Antibiotics differ from many other drugs in the fact that the treatment is for a very short time compared to drugs used to treat hypertension, diabetes, Parkinson’s, or cancer. The latter disorders have in common that the treatment, from the moment of diagnosis, is life-long. The treatment period for antibiotics is only a few weeks, making the return of investment poor. Increasing demands of authorities in both development and marketing phase and in legislation increase the costs of new antibiotics.[1] [3]

One environment where bacteria are regularly exposed to antibiotics is in large livestock operations, where producers very often treat their cows and other animals with drugs to prevent epidemics in the unsanitary and overcrowded conditions, which are common in the livestock industry. The simple reason for this is that in the short term it is cheaper to drug up the animals with antibiotics than to keep a clean living environment for them. Another big reason for these producers to drug up the animals is the fact that feeding antibiotics to the livestock makes for larger animals. The problem occurs when bacteria in these animals survive the bombardment of antibiotics, and some always do, the

With all of our modern advances, it seems somewhat strange that chronic health problems have become so commonplace. When antibiotics were discovered, they predicted the end of disease. Instead, we now have a world full of frightening antibiotic resistant infections.

Antibiotics have played an essential role in the fight against diseases and infections since the 1940’s. Antibiotics are a leading cause for the rise of global average life expectancy in the 20th and 21st century. They have greatly reduced illnesses and deaths due to diseases. With the introductions of antibiotics in the 1940’s, like penicillin into clinical practice, formally deadly illnesses became immediately curable and saved thousands of lives (Yim 2006). Antibiotic use has been beneficial and when prescribed and taken correctly their effects on patients are exceedingly valuable. However, because these drugs have been used so widely and for such a long period of time the bacteria that the antibiotics are designed to kill have adapted,

There is a huge need for antibacterial drugs as infectious diseases are the second leading cause of death worldwide and the third leading cause of death in developed countries (Projan, 2003). Over the past 60-70 years, most antibiotics have been discovered by screening of soil samples for natural products that kill bacteria, including known pathogens, first on culture plates and then in animal infections (Walsh, 2000). There are three proven targets for the main antibacterial drugs, bacterial cell all biosynthesis, bacterial protein synthesis, and bacterial DNA replication and

It is undeniable that the recent discovery of antibiotics and disinfectants in the past century is leading to the creation of increasingly dangerous antibiotic-resistant bacteria. Super bugs like Methicillin-resistant Staphylococcus have begun breaking out in hospital areas, killing more and more patients due to the lack of people following through with simple safety measures. In order to stop the creation and spread of antibiotic-resistant super bugs, proper precautions must be taken such as avoiding antibacterial cleaners, following through with instructions when taking prescriptions and maintaining adequate hand hygiene. Through adhering to basic safety rules, the creation and spread of super bugs can be minimized and all together

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).

Some antibiotics are produced from living organisms such as bacteria, fungi, and molds. Others are

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).
