Antibiotic Resistance And Its Effects On The World

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.

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 misuse and overdose of the antibiotics increase the resistance problem. It can cause these bacteria to

Antibiotic resistance has emerged as one of the greatest public health concerns of the 21st century. Nearly every type of bacteria has become stronger and less responsive to antibiotic treatment. This can eventually make it impossible to treat certain infections, leading to serious disability or death. The increasing prevalence of antibiotic-resistant bacterial infections can be attributed to overuse and over prescription. The uses of antibiotics in livestock are increasing resistance for animals and humans.

When antibiotic is used most of the bacteria die but a few bacteria with antibiotic resistance gene survive and reproduce and pass this advantage to their offsprings. This selective pressure exists naturally, however antibiotic misuse can be accused for fastening the spread of the antibiotic resistance gene [Refer to figure 2] (Learn Genetics 2015). Consequently, inappropriate antibiotic intake will lead to a greater chance of superbugs being developed. Antibiotic resistance can be defined as a new ability which a bacterium has developed to stay unattached in the presence of an antibiotic that was previously effective to destroy the bacterium (ABC science 2015). Four key mechanisms that has been identified for bacterial antibiotic resistance can be listed as: producing enzymes that inhibit the functionality of the drug, reducing the effectiveness of the drug by producing targets against which the antibiotic, reducing the permeability of the drug into the bacterium and active export of antibiotics using various pumps (Pogson 2012). All these mechanisms can be developed by any of the bacteria when the corresponding mutated gene of antibacterial resistance is received. The genes code for specific proteins, and variation in the gene leads to alteration of the shape of proteins. This leads to changing the functionality

According to the Center for Disease Control (CDC), “Antibiotic resistance is the ability of microbes to resist the effects of drugs – that is, the germs are not killed, and their growth is not stopped. Although some people are at greater risk than others, no one can completely avoid the risk of antibiotic-resistant infections” (“About Antimicrobial Resistance”). Antibiotic resistance has a higher chance of occurring with the more antibiotics taken, as the body adapts more and more each time. The CDC has collected data across the country, and has concluded that the estimated number of deaths caused by antibiotic resistance is 23,000, and that the number of illnesses is slightly higher than 2 million (“About Antimicrobial Resistance”). Already antibiotic resistance has affected millions of lives, and will continue to affect many more until antibiotic overuse is stopped

Antibiotics are used incorrectly and become resistant when a patient misuses it. By overusing or underusing antibiotics, the bacteria will adapt and become resistance to the antibiotic. When people stop taking antibiotics to treat an infection before all the bacteria is wiped out, the existing bacteria survive, adapt, and multiply. When patients overuse the antibiotics, the antibiotics kill all the bacteria, including the good ones that help defend the body. Some of the bacteria will remain because of mutations that provide them with immunity and will continue to reproduce with developed resistance to the antibiotic, with the antibiotic having no effect and without any good bacteria left. Another way bacteria becomes resistant is through animals that have been given antibiotics. The bacteria can become resistant in animals and be transferred to humans through animal

First, antibiotic resistance is the ability of infections to evolve. These new adaptations will frequently allow an infection to withstand attacks from a drug it previously could not handle. When physicians treat infections with drugs, the drug kills off all of the bacteria that cannot stand up to the medication. Sometimes, a few bacteria remain that were able to combat the drug. These bacteria continue to grow and reproduce. As a result, all of its offspring also have the DNA necessary to fight off the medication. These

The root of this problem lies in what Charles Darwin called the “survival of the fittest” in which organisms eventually adapt and evolve in response to their environment and its impending threats in order to survive. Bacteria is now doing this in response to antibiotics, which are purposed to kill bacteria so as to eliminate infections and diseases. However, now more and more bacteria are evolving to form antibiotic-resistant strains that there are no or very expensive antibiotics or treatments for yet, even if they were once easily treated diseases. Often this is a result of overuse or improper use of antibiotics by both medical professionals and patients. Overuse, such as attempting to use antibiotics for infections that do not warrant them, such as the common cold, allows existing bacteria to devise mechanisms such as “neutralizing” antibiotics, removing antibiotics, adapting their structure so as to become impenetrable to the antibiotics, or improving upon their genetics. Improper use of bacteria, such as beginning an antibiotic, but failing to use it to completion, also allows bacteria to do the

When penicillin was first administered in 1943, it proved to be extraordinary at wiping out nasty cases of syphilis, tuberculosis, gonorrhea, and meningitis infection. With the threat of these deadly infections in ‘check,’ pharmaceutical industries then cut back on their research to discover even more effective antibiotics. This new-found medical confidence inspired patients to merrily run to the clinic to get penicillin prescriptions for everything from nausea and diarrhea to running nose and sneezing, and doctors to happily prescribe the ‘miracle drug.’

There is much speculation about what has caused the increased resistance of bacteria to antibiotics and how this problem has developed.

Antibiotics have been an important instrument in public health since 1928, saving the lives of people around the world. According to the Centers for Disease Control and Prevention (2015), about half of antibiotics used in human and animals are unnecessarily and inappropriately prescribed, leading to the emergence of drug resistance in bacteria (CDC, 2015). The CDC estimates that drug-resistant bacteria cause two million illnesses and approximately 23,000 deaths each year in the United States alone (2015).

Antimicrobial resistance is the ability of microbes to recalcitrant the outcome of drugs – that is, the germs are not destroy, and their advancement is not shut. Although some people are at better chance than others, no one can fully avoid the wager of wonder drug-resisting infections. Infections with resisting organisms are difficult to discourse, request sumptuous and sometimes toxic alternatives. Bacteria will inevitably find ways of resisting the antibiotics improved by humans, which is why aggressive movement is needed now to keep modern resistance from developing and to prevent the resistance that already live from spreading. Explanation of Bacteria and Other Microbes are organisms too inconsiderable for the eye to see and are found everywhere on Earth. There are many types of microbes: bacteria, viruses, fungi, and parasites. While most microbes are unoffending and even serviceable to living organisms, some can mainspring indisposition among humans, other animals, and generate. These indisposition-causing microbes are invoke pathogens; sometimes they are apply to as “germs” or “germ.” All types of microbes have the address to develop resistance to the drudge created to destroy them, becoming dope-resistant organisms. How Resistance Happens Simply second-hand antibiotics created resistance. These pharmaceutical should only be custom to manage infections. Trends in Drug

Antibiotic resistance is rapidly becoming a major challenge in regard to modern medicine, the rapid reproduction, selection pressures and the advanced evolution of bacterial cells through a series of survival mechanisms has lead to a potentially catastrophic consequence in regard to treatment of human disease caused by bacterial infection, Antibiotic Resistance.
