Antibiotic Resistant Bacteria Essay

When a bacteria is exposed to antibiotics, they are not always guaranteed to die. This is called antibiotic resistance. Sometimes antibiotics can only stop the bacteria from multiplying (make it stagnate), and other times it causes the bacteria to multiply even more. These three results depend on antibiotic concentration, bacterial mutation, and bacterial genetic exchange.

When non-resistant bacteria are exposed to an antibiotic, most of them die. But due to the increase of mutations some of the bacteria are becoming resistance to the antibiotic. The bacteria are all subject to natural selection. Natural selection is as simple as saying that the bacteria that have not developed a mutation or resistance that helps them to survive die. The ones that do, survive and pass on the mutation to the next generation. This means that we are constantly having to adapt our antibiotics because so much of the mutation is getting passed along. The flu vaccination is a good example of how mutations are carried over and how the vaccine had to be changed every year to fight the ever changing virus. Some strains

The confusion begins with the public, and their views on the topic. The research into public perception of antibiotics has occurred multiple times, each leading to a similar conclusion: the lack of awareness leads to false perceptions about the effects of antibiotics. Per the World Health Organization (WHO), surveying 10,000 people, 64% of individuals who responded believed that antibiotics could treat the flu and the cold. This is especially odd since the same percentage of people believed that AMR “is an issue that could affect them and their families” (World Health Organization). Due to the constant confusion, about if

Antimicrobial resistant has been called one of the world's most pressing public health problems. Every time a person takes antibiotics, sensitive bacteria are killed, but resistant ones may be left to grow stronger and multiply. Although antibiotics can help treat bacterial infections, a possible side effect is that they can strengthen certain bacterial strains. Antibiotics are supposed to be used for bacterial infections, but are wrongly being used for both viral and bacterial infections. When we use antibiotics on viral infections, deadly bacteria multiplies and becomes stronger. We can fix this problem by using antibiotics for bacterial infections only.

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

Antibiotics have always been one of the most reliable drugs in medical history, making them a saving grace for those who suffer from bacterial caused illnesses. Although many types of drugs are used to cure diseases, are antibiotics actually capable of completely “curing” a patient? Many people find antibiotics to be a reliable source when it comes to fighting of an infection, however, when someone either overuses or misuses the prescription of antibiotics, harsh side effects may occur. One of the main problems that comes with the abuse of antibiotics being the resistance of them for future use. This becomes a major problem when further down the road a severe illness is accumulated by someone, but cannot be treated due to the resistance.

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

It can cause something as small as a cold to be able to kill a person. “Eric was prescribed to many antibiotics as a young child that when he became sick at the age of 10 the had to try 4 different medications before he would start the get better.”(Renkl, Margaret) When bacteria becomes immune to antibiotics the body has no defense over the disease. The bacteria is stronger than the body’s immune system because it has cell walls when human cells do not have walls to protect itself. It can cause serious damage to a person’s body, sometimes so serious that when not treated properly it can even lead to

Antibiotics are medicines that are used to treat bacterial infections. Antibiotic resistance means that an antibiotic is no longer effective in treating an infection. Resistance can develop if you use antibiotics the wrong way.

The general populace of western civilization may believe that modern medicine is limitless and that numerous afflictions that are common can be easily resolved with the major strides medicine has taken in the past century. In the case of antibiotics, this couldn’t be farther from the truth and its use leaves a nasty prospect for the future. Antibiotics, the type of drug that is capable of killing harmful bacteria, is widely regarded as a simple gift from medical research and is expected to be prescribed for even the mildest of illnesses. However, the use of antibiotics has proved that it comes with a terrible byproduct: leftover bacteria that survives the drug and evolves strains that are resistant to the drugs the world currently

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

Antibiotics have played a major role in our society thanks to Sir Alexander Fleming's careful observations in 1928. Without it, many lives would be in danger due to infectious diseases. Antibiotics are chemical substances produced by various species of microorganisms and other living systems that are capable in small concentrations of inhibiting the growth of or killing bacteria and other microorganisms. These organisms can be bacteria, viruses, fungi, or animals called protozoa. A particular group of these agents is made up of drugs called antibiotics, from the Greek word anti ("against") and bios ("life").

Antibiotics was developed to combat bacteria by zero in on the bacteria’s structure. As time goes by bacteria can defeat antibiotics in their natural selection. Natural selection plays an important role in the progression of antibiotic resistance. Most of the bacteria dies when it is exposed to antibiotics they are sensitive to. Therefore, it creates more space and availability of nutrients for the surviving antibiotic-resistant bacteria. Subsequently,

The misuse of antibiotics encourages evolution in the bacterium so that it is no longer affected by the drug. If the bacterium spreads, then people contracting it are at risk of an untreatable infection, no matter how conscientious they have been in their past use of antibiotics. (2001)
