AAntibiotics

Antibiotics are a chemical which work by being either bactericidal where they kill microorganisms; or by being bacteristatic where they inhibit the growth of the microorganisms. Narrow spectrum antibiotics target specific reaction in particular microorganisms; whereas broad spectrum antibiotics will have an effect on more general features so affect a wide range of pathogens.
They work by cell wall synthesis: an example of a bactericidal antibiotic is Penicillin, this works by preventing the production of peptidoglycan which is a substance that forms in the cell wall. This means the cell will continue to grow without dividing or developing new cell wall Therefore, the wall gets weaker, and eventually ruptures. Another way antibiotics works is by protein synthesis: an example of a bacteriostatic antibiotic is Tetracycline, it binds to ribosomes in bacteria this means the cell cannot make proteins and therefore inhibits growth.
The benefits of using antibiotics is that it helps people with weakened immune systems, it can treat many infections such as strep throat, tonsillitis and sinusitis, it is easy to administer since you can take them orally or via injection, it has few side effects and is cost effective. However issues concerning antibiotics are allergic reactions depending on your drug allergies you may be extremely allergic to some types of antibiotics, such as those containing sulfa. Unfortunately, sulfa is present in many common antibiotics, so it may be more difficult to find a suitable medication for your illness. Also drug-resistant bacteria, if you do not take the full dose of an antibiotic, it only kills some of the bacteria in your system and can make the rest antibiotic-resistant, which means antibiotics may not work as well for you in the future. Moreover potential side effects, while many antibiotics have few side effects, some…...

Viruses and Antibiotics

...characteristics. 2. Viruses cannot be grown agar as bacteria are because they cannot metabolize on their own. They need at least one host cell where it could input its DNA and infect it. After that, both those viruses would commence by infecting other living host cells. 3. Antibiotics work to get rid of the replicating function of bacteria so it cannot spread. However, viruses cannot replicate on their own unless they have living hosts, therefore since the viruses do not replicate, the antibiotics have no use. 4. Viral specificity means that the virus chooses and selects the type of cell, organism to infect and which disease to invoke onto it. 5. a) A-Virus, B-Cell DNA, C-Cell/Cell Membrane, D- Nucleic Acid (DNA or RNA) b) Bacteriophage Life Cycle c) I believe it doesn’t matter what they infect, as they are non-living and as long as they find some kind of living host, they’ll inject their nucleic acid to replicate into many more viruses. 6. Antibiotics literally will have no effect and will not cure the patient. All that the patient will gain are the side effects, for example: drowsiness and such. They will not get cured, as their problem is that viruses aren’t alive and antibiotics only deal with live things.

Antibiotic Misuse

...There are several people who use antibiotics for the wrong reasons. Some people think that using antibiotics will get rid of a cold or the flu virus faster or clear up a skin condition. Antibiotics should only be consumed for the infectious illness in which they were suggested for. Antibiotics are abused world-wide, and abuse of the medication can do more harm than help. I chose to research antibiotic abuse and the underlying issues with antibiotics. Antibiotics are being abused in so many ways by people and industries everywhere. The focus will be on agricultural abuse of antibiotics, human abuse, and antibiotic resistance. I will conduct various phone or face to face interviews with individuals as well as provide a questionnaire survey to obtain the information needed for this particular project. What are antibiotics? Antibiotics are “A medicine (such as penicillin or its derivatives) that inhibits the growth of or destroys microorganisms”, (What You Should Know about Antibiotics, 2012, p. 3). Antibiotics are used to treat various infections within the body cavity. They help ward off unwanted illnesses. There are various types of antibiotics each one has a significant role in fighting bacteria or fungal infections. “How do antibiotics work? When properly prescribed for a bacterial illness, antibiotics join forces with your body’s own defenses and literally wage war against invading bacteria. Some antibiotics dissolve the protective cell wall of an organism, rupturing......

Antibiotics in the Production of Food Animals

... Antibiotics in the Production of Food Animals Lawrence S. SwaderDeVry UniversityEnglish 135 Professor Hanson12/5/2011 | Antibiotics in the Production of Food Animals The use of antibiotics in the production of food animals has caused some controversy of late. Antibiotics have been used in food animal production in the U.S. and other countries for more than 50 years (Ontario Ministry of Agriculture, Food and Rural Affairs, n.d). Antibiotics are used in agricultural applications not only therapeutically to treat illnesses and infections, but also as a non-therapeutic growth agent. This use as a growth agent has been a boon to the meat producers and consumers of the world. It has allowed for quicker weight gain and thus shortened time from birth to slaughter. This increases production and lowers prices to consumers. So, why all the controversy now. It is this non-therapeutic use or use for something other than treating illness or disease that has spawned most of the controversy around their overuse and raised calls that antibiotics be banned in agricultural use for anything except the treatment of illness or disease. Although antibiotics have contributed to an increase in production and the lowering of cost of industrially produced meat there is also a serious downside. According to FDA estimates fully “80% of the antibiotics produced in the U.S. are for agricultural use. Four times the amount used to treat human illnesses” (Union, 2011). The use of antibiotics in......

Antibiotics

...Antibiotics have saved numerous lives since the innovation of penicillin antibiotics in 1928 by Alexander Fleming. Although, now there is a increasing anxiety that overuse of antibiotics can direct to avoidable side effects and the expansion of drugs which are mostly opposing bacteria such as MRSA (methicillin-resistant Staphylococcus aureus).  MRSA has happened to be the most frequent organism responsible for skin, soft tissue and surgical-site infections in the United States and in different parts of the Europe. Different findings had been conducted in a study of the genetic code of MRSA samples; they have added these samples to support to the theory that the introduction of extensive antibiotic use in the 1960s may have generated MRSA disease. Antibiotic word is an originated from Greek for anti, which means against and bios means life. A micro –organism bacteria is a life figure that is moreover good, living in our lower part of the canal near stomach and anus which called intestine, such bacteria’s infecting our bodies and making the world population ill. Antibiotics are a kind of drugs used to treat these infections caused by bacteria. Healthy immune systems can be destroyed by bad bacteria before they can cause disorder in the whole body which causing illness. Human bodies assault the bacteria by transferring white blood cells to the unsafe bacteria separating the good bacteria unaccompanied. Antibiotics are frequently used for higher respiratory infections. But the......

Antibiotic and Surgery

...Antibiotic in Surgical Patients Gretchen Smith Antibiotic in Surgical Patients Prevention of surgical infections is a highly significant issue to pre-op nursing care, as surgeons entrust nurses to carry out the procedure, of administration antibiotic prophylactic, which have a positive impact on patient outcome. When a surgeon determined that an antibiotic is going to be required for a particular case, giving the antibiotic at the correct time is “very important” (“Case example,” 2010, p. 27). Research has found that antibiotics that are administered (“to early or after surgery begins are not effective” (“Case example,” 2010, p. 27). It is important for nurse to be aware of the timetable and take steps to implement this in to their practice. It has been debated as to whether or not antibiotic prophylaxis is appropriate in preventing infections in surgical patients. (Easter, 2010). Zaidi, Tariq and Breslin (2009), addressed the topic of timing an antibiotic prophylaxis, the researches study 525 elective surgeries and the timing of antibiotic administration. Zaidi, Tariq and Breslin stated that the “antibiotic should be administered as near to the incision time as possible,” as the study found that “pre-incisional prophylaxis administration of antibiotics is more beneficial than post-incisional administration” (Zaidi, Tariq, & Breslin, 2009, p. 226) The most significant risk factor for delivery by cesarean section is post partum infection.

Overuse of Antibiotics

...The New England Health Institute (NEHI) considers antibiotic overuse a $63 billion issue that desperately needs reform. The solution to the overuse of antibiotics has already been started by the Centers for Disease Control (CDC). The CDC implemented an educational program discussing the treatments of viruses and bacterial diseases aimed at patients or the parents of patients as well as health care providers. This program called, Get Smart, Know When Antibiotics Work, discusses the dangers of demanding an antibiotic when the drug will not be effective and outlines options for doctors to discuss with patients (Bend the Curve, 2013). Another part of the reform effort suggests increasing vaccinations to combat antibiotic overuse. By increasing the use of flu shots, the need for antibiotics will diminish. The NEHI favors reform of the guidelines in hospital clinics and other health care settings making it policy to not prescribe antibiotics unless the treatment calls for them, no matter what the patient demands. If all health care professionals respond this way, patients will eventually accept the practice. NEHI considers antibiotic overuse a major player in the health care reform setting including antibiotics given to, or put in the feed, of animals that later become food. Work to decrease antibiotic use in this area impacts human medicine as much as efforts to decrease antibiotics prescribed to humans (Bend the Curve, 2013). Not only are there action that can be taken by......

Antibiotic Resistant Bacteria

...Antibiotic-Resistant Bacteria Kwame D. Brooks BIO/101 October 16, 2014 Prof. Rafael Frim Antibiotic-Resistant Bacteria Even though the indiscriminate use of antibiotics is enhanced by their free and uncontrolled availability ‘across the counter’, particularly in developing and Third World countries where regulatory mechanisms leave much to be desired. Alternately, even in developed countries, there is a clear connection between overall antibiotic intake and the rate of recurrence of the discovery of antibiotic-resistant bacteria. According to Barry Commoner, “First law of ecology: ‘Everything is related to everything else’.” As such, these antibiotic-resistant bacteria evolves into a most important health problem that becomes the foundation for some patients to be incurable to previously treated infections because the development of antibiotic resistance. This is primarily due to disproportionate and often superfluous use of antibiotics in humans and animals. According to G. Gopal Rio “Risk factors for the spread of resistant bacteria in hospitals and the community can be summarized as overcrowding, lapses in hygiene or poor infection control practices. Increasing antibiotic resistance in bacteria has been exacerbated by the slow pace in developing newer antibiotics and bacteria can be innately resistant or may acquire resistance to antibiotics” (1998). In essence, these two types of conflict are probably in the same way significant in the perspective of the......

Antibiotic Resistance

...Antibiotic Resistance Essay Many things were learned while completing this study. I learned that education is one of the keys to reducing the amount of antibiotic resistance. Educating parents who insist on getting antibiotics for every sniffle on the danger of over medicating with antibiotics might help. Educating the general public via infomercials might also help them realize the dangers as well? Doctors need to stand their ground and take back the ground they have lost over the years. Realize it is okay to tell a parent in a kind way, “I am the doctor this is what I know is best for your child or for you.” It would be a good thing to cut back on the ability to get prescription drugs without a prescription. It is too easy to get on the computer and purchase drugs from overseas pharmacies. Make the penalty for doing this like the penalty for illegal substances. If enough people are punished they will decrease maybe. Some would have you believe the government does not control this problem as it is a way of population control, and if one is stupid enough to buy drugs without a prescription then the consequences are deserved. Ignorance is not an excuse. Although the conspiracy theorists are out there what is the truth? We may never know but as long as one does what they are supposed to there is no need to worry. It seems the FDA is already aware of the use of antibacterial soaps as a problem and they seem to be already addressing it but not allowing big......

Antibiotic Resistance

...Antibiotic resistance — what is it and why is it a problem? The development of antibiotics was one of the most important advances of medicine. Many bacterial infections (e.g. tuberculosis and infected wounds) that had previously had no effective treatment and often killed people, became treatable with antibiotics, saving millions of lives. Now, because of the overuse and misuse of antibiotics, bacterial infections that were once easily cured with antibiotics are becoming harder to treat. This is due to antibiotic resistance. The World Health Organization has called this one of the biggest threats to human health today.   What is antibiotic resistance? Antibiotic resistance happens when bacteria change to protect themselves from an antibiotic. They are then no longer sensitive to that antibiotic. When this happens, antibiotics that previously would have killed the bacteria, or stopped them from multiplying, no longer work. What are ‘superbugs’? ‘Superbugs’ are bacteria that are resistant to several different antibiotics. The methicillin resistant Staphylococcus aureus (MRSA) bacteria commonly found in hospitals, and the bacteria that cause tuberculosis (Mycobacterium tuberculosis), are now very hard to treat because of antibiotic resistance. Strains of Escherichia coli (E. coli) — the bacteria that causes many urinary tract infections — have also developed resistance to a number of antibiotics. How does antibiotic resistance affect me? Using antibiotics when you......

Antibiotics: a Harmful Misued Product

...Antibiotics: A Harmful Misused Product Today, the human race has way too much reliance on antibiotics and products associated with them. Many people are extremely unaware of what can happen if antibiotics are overused or used incorrectly. Nobody allows their body to heal itself. In certain cases antibiotics should be used to help cure one of an infection but not in the ways they are used today. Antibiotics can be found in many household that includes mostly all wipes and sprays. Antibiotics being included in all of these products can do nothing but hurt one in the long run. Placing antibiotics in cleaning appliances can cause all bacteria to become immune and change so that the antibiotic becomes unproductive and the bacterium becomes stronger. Antibiotics are used for anything from cuts to strep throat and pneumonia and have been for a very long time. They are becoming impotent because they are used incorrectly by nearly everyone: doctors, patients, and even people raising animals for meat. The misuse would be prescribing the drugs completely incorrectly. In doing this, superbugs are produced and they are extremely antibiotic resistant and almost impossible to stop. Antibiotics also kill some of the good and helpful bacteria inside of the body which may allow resistant bacteria to fill in. The human body itself has sets up its own defenses with pathogens and other walls that fight and harmful bacteria off without any use of antibiotics. It is very faulty to overuse any......

In the biotic environment organisms acquire resources through completion, predation, and parasitism. The abiotic environment includes weather conditions, dependent chiefly on temperatues and precipitation. Directional selection occurs when an extreme phenotype is favored and the distribution curve shifts in that direction. Such a shift can occur when a population is adapting to a changing environment. Resistance to antibiotics and insecticides are examples of directional selection. The widespread use of antibiotics and insecticides (pesticides) results in populations of bacteria and insects that are resistant to these chemicals.
