Essay on Antibiotic Usage

Antibiotic resistance is a phenomenon in which germs evolve to be able to resist the action of drugs. This causes illnesses that were once easily curable with antibiotics to become dangerous infections, requiring alternative medications or higher doses. With millions of deaths increasing every year, antibiotic resistance has become one of the world's most pressing public health problems. This essay will explain the key causes of the emergence of resistant bacteria, including antibiotic misuse, inappropriate prescribing and availability of few new antibiotics, and outline relevant effects of antibiotic resistance.

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.

The third and final factor in bacterial resistance to antibiotics is bacterial genetic exchange. It is very common for bacteria to share genetic info between cells even if the bacteria are not the same species. When this happens, genes and DNA get mixed into different species allowing more mutations against the antibiotics.

A majority of pharmaceutical companies thought that penicillin was to be a cure for any infection. At first no one expected that bacteria would mutate and become stronger. Initially pharmaceutical companies stopped doing research for new antibiotics and concentrated on other areas. As the result,

Antibiotic resistance evolves in bacteria. Charles Darwin created the theory of evolution which focused on natural selection being the key factor of how things change. Natural selection is when organisms that are better suited to the environment are able to reproduce successfully. Evolution is descent with modification. Bacteria can become resistant to antibiotics by a mutation. The bacteria that did not die from the antibiotic inherited the gene from an ancestor that made it resistant. Since the other bacteria is dying faster than the resistant bacteria, the resistant bacteria are able to multiply

Antibiotic resistance is when microorganisms, such as bacteria, are able to survive an exposure to antibiotics and these bacteria are now resistant to the effects of these antibiotics. Antibiotic resistance in bacteria has been an issue since antibiotics were discovered. The fact that bacteria can become resistant to our medical treatments such as antibiotics is a natural evolutionary process, but there are certain human contributions that definitely speed up the process. For example, one of the main contributions that will be discussed is the problem of over prescription of the antibiotic drugs. The

The documentary Resistance explains how using antibiotics on livestock enables farmers to house animals in deplorable conditions and maintain their health efficiently. Although high heat kills them, the superbugs spread from animals to people through raw or undercooked meat. This constant treatment of antibiotics allows for the bacteria to develop a way around the antibiotics, making it more difficult for hospitals to treat

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,

Another crucial element to consider is the emergence of bacterial strains resistant to antibiotics,given the widespread use of these drugs as a prophylactic or a therapeutic regimen.

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.

Dr. Martin Blaser, author of Missing Microbes: How the Overuse of Antibiotics is Fueling Our Modern Plagues, paints antibiotics as a negative force in the world that causes disease. Dr. Blaser has studied the role of bacteria in human disease for more than thirty years at Vanderbilt University, and has experience as the director of the Human Microbiome Project at New York University. He also works with the National Institute of Health on infectious diseases. Meanwhile, Dr. David Shlaes, author of Antibiotics: The Perfect Storm, focuses on the drugs’ ability to cure disease. Dr. Shlaes has worked for 30 years in anti-infective academia, industry, and consulting. He served as Professor of Medicine at Case Western Reserve University for five years, and then moved to industry, where he became vice president of Infectious Diseases at Wyeth Research. Later, he took a position as executive vice president of research and development at Idenix Pharmaceuticals in Cambridge, Massachusetts, and formed his own consulting company. He now works predominantly with biotech companies and venture capital firms in their evaluation of anti-infective companies. While they take different approaches, the two doctors concur that antibiotic resistance is a major problem and that society needs to find ways to slow it down. One way to slow down the spread of resistant bacteria is finding ways to ensure

As previously discussed, antibiotics often work by targeting critical functions of the bacterial cell. This means that antibiotics have specific targets, which is a boon because it means non-microbial life will not be affected by the antibiotics. However, because of this specificity, bacteria can develop ways of protecting themselves from antibiotics, leading to the rise of antibiotic resistance

Antibiotic resistance is, in simplest terms, just natural selection – but at a hugely exacerbated rate. We can see the effects of natural selection in ourselves; that’s why we don’t have webbed fingers, because they didn’t exactly benefit the terrestrial human race. But while it takes human beings 20-30 years to reproduce, it takes most bacteria 20-30 minutes. Think about that for a second. By reproducing every 20 minutes, a single E. Coli bacterium can create 70 billion new bacteria in just 12 hours. About 2% of those bacteria will have some type of mutation, and

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).

This review presents the salient aspects of antibiotic resistance development over the past half-century, with the oft-restated conclusion that it is time to act.
