Recommended: Essay on the importance of antibiotics

Antibiotics are used worldwide and although their uses have helped many people, it doesn't come without risk. The use of antibiotics treats people and animals alike to cure infection and are easily excusable through physicians. However in recent years, since antibiotics are used so universally, antibiotic- resistant strains have become a growing problem. This suggest that the bacteria is adapting to the antibiotics and through natural selection, the antibiotic- resistant bacteria have grown in numbers. The scientific community worries about future treatment of diseases if the bacteria continues to adapt. For example tuberculosis which hasn't been a problem in some time, has started to reoccur as a much harder to treat strain. Antibiotics are the go to method of treating infection but we need to be careful when we are using them. …show more content…

However, scientist have begun to find that farm animals such as chickens have bacteria in their food that has resisted even the strongest antibiotics. This is extremely worrying because animals such as chickens, cows and pigs are consumed by people. Which means that if the animals is infected, the infection can pass to the human population. For now these bacterias are harmless but the problem still remains; what would happen if out animal food supply is infected and we are unable to cure it?
The bacteria are adapting through a process called natural selection. Natural selection is the way the environmental conditions determined which organism survive to reproduce. This applies to antibiotics because the bacteria that develops mutations that are resistant to antibiotics survive and reproduce. The overuse of antibiotics allows the bacteria through the process of natural selection to adapt faster and than reproduce the antibiotic resistant bacteria as a more common

    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.

    Bacterial resistance to antibiotics has presented many problems in our society, including an increased chance of fatality due to infections that could have otherwise been treated with success. Antibiotics are used to treat bacterial infections, but overexposure to these drugs give the bacteria more opportunities to mutate, forming resistant strains. Through natural selection, those few mutated bacteria are able to survive treatments of antibiotics and then pass on their genes to other bacterial cells through lateral gene transfer (Zhaxybayeva, 2011). Once resistance builds in one patient, it is possible for the strain to be transmitted to others through improper hygiene and failure to isolate patients in hospitals.

  • Anti-Bacterial Resistant Superbugs

    1192 Words  | 3 Pages

    Antibiotic-resistant bacteria are created when mutations in the pathogen's genetic code occurs, changing the protein in the bacteria that the antibiotics normally go after into a shape that the antibiotic can not recognize. The average bacteria divides every twenty minutes, so if a contaminated spot has one single bacteria in the morning, there could be trillions on that same spot at the end of the day. That means that when counting all the possibilities of mutations, the amount of mutated offspring that the bacteria might have formed during those replications could be as high as in the millions. Fortunately though, this does not happen so frequently that it is normally an issue. The amount of non-mutated bacteria vastly outnumbers the mutated ones and many of the mutations occurring in the bacteria usually have either a harmful effect, or not effect at all on its function. That means that the pathogen is still relatively less harmful than it c...

  • Excessie Use of Antibiotics

    Over the years humans have tried every possibility to overcome the health problems, spread of epidemics and infections, disease control and have worked towards a healthy society free of disease and health problems. They have succeeded to a great extent. The book “Good germs, bad germs” describes that though the life expectancy is now far more as it was in previous eras. Epidemic problems and infectious diseases are now getting lesser and lesser and humans are being treated successfully. The hygienic conditions have also been improved so as to ensure least growth of microbes, germs, parasites and bacteria. Antibiotics have been invented to address diseases and infections caused by bacteria and viruses. With all these substantial efforts the biologists, physicians and scientists have triggered another epidemic which is even more severe. They have killed those microbes and bacterial species which were human friendly and as a result of either their disruption or mutation, pathogenic bacteria have even become more active and resistant to treatments. This has led to increased ineffectiveness of antibiotic drugs, low immunity and various infections and inflammatory diseases. The chlorinated water for drinking and food processing along with excessive hygienic conditions indicates our fight against these bacteria and germs. Further, these antibiotics are even given to the livestock which becomes our food and as result many of their resistant germs end up in our digestive tract and other organs. Thus, the war against microbes through excessive cleanliness and use of antibiotics has resulted in antibiotic resistance among humans, which has become one of the prominent problems of medical science

    Factory farming is a necessary component of our modern food production and supply system. In 2005, the U.S. produced 45.7 billion pounds of red meat. It efficiently produces and distributes huge quantities of food to feed the growing population of America. But the overfeeding of antibiotics in the U.S. meat industry has gotten to the extreme and it calls for a drastic change in order to prevent a potential public health crises.

    However, health concerned organizations want to ban the use of these products due to the increasing fears that they can cause harm to the consumers. For over 50 years, antibiotics have been added to the food of animals such as poultry, cattle and pigs. The main purpose for doing so is to lower the risk of disease in animals. Farm animals are housed together in overcrowded areas, which are very dirty. The hygiene level can get to such a poor state that they are often in contact with their own excreta as well as excreta of the other animals they are housed with and because of tight single air space they share, the likelihood of catching diseases from one another is further increased and very often a whole heard can be infected at one time.

    The threat of antibiotic resistant bacteria emerging through the increase in usage of antibiotics has become a global health concern. Antibiotic resistance bacteria cause infections that are unable to be treated by normal measures that lead to prolonged illness and greater risk of death. The number of antibiotic resistant strains threatens health security, the control of infectious disease, increases the cost of health care, and can damage trade (World Health Organization, 2013). Animal husbandry and the use of sub-therapeutic antibiotics in animal feed are listed as two of the major factors leading to the acceleration and sprea...

  • The Evolution of Antibiotic Resistant Bacteria

    1427 Words  | 3 Pages

    Resistance first appears in a population of bacteria through conditions that favor its selection. When an antibiotic attacks a group of bacteria, cells that are highly susceptible to the medicine will die. On the other hand, cells that have some resistance from the start or acquire it later may survive. At the same time, when antibiotics attack disease-causing bacteria, they also attack benign bacteria. This process eliminates drug-susceptible bacteria and favors bacteria that are resistant. Two things happen, populations of non-resistant and harmless bacteria are diminished, and because of the reduction of competition from these harmless and/or susceptible bacteria, resistant forms of disease-causing bacteria proliferate. As the resistant forms of the bacteria proliferate, there is more opportunity for genetic or chromosomal mutation (spontaneous DNA mutation (1)) or transformation, that comes about either through a form of microbial sex (1) or through the transference of plasmids, small circles of DNA (1), which allow bacteria to interchange genes with ease. Sometimes genes can also be t...

    The most effective way to combat pathogenic bacteria which invade the body is the use of antibiotics. Overexposure to antibiotics can easily lead to resistant strains of bacteria. Resistance is dangerous because bacteria can easily spread from person to person. Simple methods for preventing excessive bacterial spread are often overlooked. Not all preventative measures are even adequate. Doctors and patients often use antibiotics unnecessarily or incorrectly, leading to greater resistance. Antibiotics are used heavily in livestock and this excessive antibiotic use can create resistant bacteria and transfer them to humans. In order to reduce resistant bacteria,

    It is estimated that over one-half of the antibiotics in the U.S. are used in food animal production. The overuse of antimicrobials in food animal production is an under-appreciated problem. In both human and veterinary medicine, the risk of developing resistance rises each time bacteria are exposed to antimicrobials. Resistance opens the door to treatment failure for even the most common pathogens and leads to an increasing number of infections. The mounting evidence of the relationship between antimicrobial use in animal husbandry and the increase in bacterial resistance in humans has prompted several reviews of agricultural practices by scientific authorities in a number of countries, including the US.
