Antibiotics

Antibiotics are a medicine that inhibits the growth of or destroys microorganisms that cause infections and diseases. Since the drug 's inception in 1929 we have seen a dramatic reduction in deaths caused by infection and many other bacterial based diseases. Antibiotics have increased the longetivity of people 's lives around the world; it 's now a rarity to hear of people dying of bacterial infections in modern world. Recently we have seen certain types of bacteria develop resistance to…

The Evolution of Antibiotic Resistance in Bacteria Bacterial infections are a leading cause of death all over the world, especially in children and the elderly, whose immune systems are not at their peak. The discovery of antibiotics in the 1940s provided doctors with a powerful weapon against harmful bacteria, often times by inhibiting their protein synthesis or cell wall formation. Within a few years of their use against certain bacteria, however, some antibiotics’ effectiveness began to…

Antibiotics How do you feel about antibiotics? Are they helpful or are they harmful, are they safe or are they dangerous? The current situation we are dealing with right now is should everyone have access to antibiotics in their homes. Today as of 2016 “antibiotics are life-saving drugs” (Dryden, M) but can be harmful if we don’t use them correctly. “Everyone prescribing antibiotics should consider both their clinical and public health responsibilities” (Dryden, M) because antibiotics…

The increase in antibiotic resistant bacteria is a substantial issue in the medical world today and is one of the greatest threats to the survival of the human species. Many bacterial infections that were once treatable with antibiotics are becoming increasingly untreatable, due to the bacteria being overexposed to antibiotics and consequently developing resistances to them. The use of antibiotics agriculturally in livestock and with veterinarians with pets are also factors in the increase…

In the United States and worldwide, there is a serious problem of antibiotic over prescription and unnecessary prescription. This problem represents a tragedy of the commons and negative externality, as each course of antibiotics reduces the overall effectiveness of the drugs and contributes to the rise of antibiotic-resistant bacteria. This paper attempts to estimate the negative externality associated with antibiotic prescriptions, especially when they are needlessly prescribed. Further, this…

Biology Antibiotics Assignment Introduction Bacteria are microscopic prokaryotic cells, they are very common and are found in every habitat on earth (Introducing Microbes, n.d.). There are many harmless bacteria however bacteria are the cause of many diseases including salmonella, pneumonia and meningitis (Cynthia Haines,2013). To combat these diseases caused by bacteria in 1928 Alexander Discovered the first antibiotic, it was used to treat soldiers in ww2 with infections which could…

defenses. In the case of fungi, specifically the Penicillium genus, their chemical defenses are against bacteria, in the form of antibiotics. In the early 20th century, scientists adapted these chemicals into antibiotics for human consumption (Wennergren 141). Since then, antibiotic use has grown tremendously, and they are now being used to treat bacterial infections in…

Antibiotic resistance also known as Antimicrobial resistance (AMR) is when bacteria acquire the ability to resist the destructive and lethal effects of an antibiotic. New strains of resistant bacteria appear via mutations that introduce an antibiotic resistant gene and then evolve by “Survival of the Fittest". In presence of antibiotics, alleles providing bacteria with resistance are under strong selective pressure. Hence, surviving strains will be in a competition free environment, they will…

Antibiotic Resistance Introduction: One of the challenges affecting the medical world is antibiotic resistance. This is a concern because antibiotics have been used for decades to treat hundreds of diseases. I was able to find two articles that go over this issue. The first one was found on http://www.cdc.gov/drugresistance/about.html and the second on http:/x/www.medicinenet.com/antibiotic_resistance/article.htm. These articles are informative. They help answer some of the important questions…

If antibiotic resistant infections were reduced “by just 20 percent, [the population] would save 3.2 to 5.2 billion dollars... each year.” (Medical) The seriousness of antibiotic resistance is becoming increasingly evident and is gaining global attention to the point of being recognized on epidemic levels. Antibiotics were made to aid the body’s immune system and fight off bacteria, however studies are being conducted proving that antibiotics may be harmful and not always necessary; therefore,…
