Antibiotic Resistance Essay

Bacteria are not just all of a sudden becoming resistant to antibiotics they have always had a bit of resilence, as a human species we have always developed something it doesn’t work we will develop something stronger, that has been the downfall in this instance. Pencillan is a great example as it is one of the most highly used antibiotic and is derived and made from mold.

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

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

The Centers for Disease Control and Prevention (CDC), describes antibiotic resistance is the ability of bacteria or other microbes to resist the effects of antibiotic treatment. () So instead of being destroyed by the medications, the bacteria survives and continues to reproduce, resultant in new communicable diseases that even more difficult to treat.

Also known as superbugs, these bugs are resistant to our modern day antibiotics. People around the world are trying to figure out alternatives to this plague. These bugs have evolved over years and years becoming stronger and passing down genes from generation to generation, To slowly become the super bugs that they are known as today. Often these resistant genes are caused by overuse of antibiotics by humans and farm animals, but this is not always true. Recently the ARS (the American Recorder Society) found antibiotic resistance in prairie soils that had no human contact. Antibiotic resistance is commonly viewed as a result of antibiotic overuse in humans and animals, Recently found antibiotic-resistant

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

Studies show that twenty-three thousand out of two million with infection dies because antibiotic resistance(Center for Disease Control). What exactly is antibiotic resistance and how did bacterias become resistant

Frequent antibiotic use over long periods of time puts selective pressure on bacteria, and causes resistance to spread. When an antibiotic is used to treat a typical bacterial infection, most bacteria are killed. Sometimes, however, a bacterium with an advantage lives. This bacterium can then reproduce and pass its advantage on, creating many more antibiotic resistant bacteria.​ Sometimes in medicine, antibiotics are used too often or incorrectly, which can cause resistance to spread faster than it would

Mutations and genetic evolutions in the bacteria are two ways resistance is growing. These mutations and genetic evolutions get passed down to the next generation, which makes it difficult for scientists to create antibiotics that work each specific strain of bacteria ("Facts about Antibiotic Resistance" 2016). Many resistant antibiotics have targeted the cells by inhibiting the enzymes that usually stop the spread of the bacteria (Diekema 2016). Scientists need to look into preventing these enzymes from getting blocked so the antibiotics can stop the replicating

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

Antibiotic development is one of the modern marvels of medicine. This is the first external tool that people have to fight against bacterial infections. The first drug developed was Penicillin. This medication is so effective that it is still used today. From its structure, every other antibacterial drug was developed. Today, there are hundreds of options available for treating infections. Unfortunately, this has had significant ramifications on the development of resistance to these medications. As the infections continue to learn and evolve, it is important that people educate themselves on what this means and the impacts it has.

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

For a bacterium to become resistant a change in its DNA must occur. This can happen in more than one way. Bacterium may gain resistance through spontaneous mutation within the bacterium’s DNA. This occurs when a single amino acid that makes up a protein changes arrangement, the order of the peptide chain (made up of amino acids, joined together to make up proteins) then the purpose of the protein in the DNA changes. This causes the genetic makeup of the cell to alter. If the mutation is of benefit and gives the bacteria resistance, once all the other none resistant strains of bacteria are killed, the resistant bacteria multiplies and reproduces, creating a new strain of bacteria which is resistant to the antibiotic in hand. Once a resistance gene is obtained and inserted into the DNA, the bacterium can dominate other bacteria and

At this time, practically all Gram-positive infections were vulnerable to the penicillin. However, today, infections caused by bacterial agents such as Staphylococcus aureus are resistant to penicillin, and of those, 50% are resistant to stronger drugs. Human actions that have aided and accelerated the process of evolution regarding bacterial resistance to antibiotics include the misuse of antibiotics by health professionals (more than 40 million of antibiotic prescriptions in 2011 were unnecessary), poor drug quality, unhygienic conditions enhancing the spread of resistant bacteria (mostly in developing nations) and inadequate surveillance (patients not completing their course of antibiotics and the strongest/resistant bacteria

Antibiotic resistance or superbugs is / are global issues. They might not be as much of a problem now but they can wipe out thousands of people with a snap of the fingers. I think we can fight the superbugs by not abusing drug use and not giving drugs to animals that we eat. Superbugs are a certain type of bacteria that is immune to all medicine that you throw at it and can be very deadly. Antibiotic resistance is one of the world 's most worrisome health issues. Improper use of antibiotics are the main cause of drug resistant bacteria.I think we can fight the superbugs / antibiotic resistance by not abusing drug use and not giving drugs to animals that we eat. Also by using drugs / medicine properly and not overusing them. Here is some information on antibiotic resistance to help you know more about it, know how to prevent it and finally be cautious when eating at fast food restaurants.
