Introduction I. Antibiotics are among the most frequently used medications in the world today. A. They can cure anything from your minor discomforts to a life-threatening disease. B. However‚ if misused‚ antibiotics can cause many problems. II. Antibiotics are so overused‚ that the human body is becoming resistant to its cures. III. This morning I will show you that misusing antibiotics can be done without a person even realizing that they are doing it. A. First‚ antibiotics are used to feed

Antibiotic Resistance Nicholas J. Ciotti Nova Southeastern University Biology 1510 Professor A. Hirons March 28‚ 2011 Abstract 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

United States is pediatric overuse of antibiotics. The audience to whom the responsibility of this problem falls includes pediatricians and family practice physicians who are in the position to prescribe and administer antibiotics to children. Antibiotics have been one of man’s greatest discoveries in the medical realm; saving thousands of lives that would have otherwise succumb to harmful‚ disease-causing bacteria.1 However‚ with the discovery of antibiotics has also come the misconception that they

The day to day is the term used to refer to antibacterial which are only indicated for the treatment of bacterial infections‚ there is more than 15 classes of drugs that differ in chemical structure and activity against bacteria. A certain antibiotics may be effective against one or various bacteria. These drugs should not be used

Antibiotic Lab Report By: Sierra Toll Hour: 6 Title: The effects of antibiotics on the growth of Escherichia Coli Problem: How do antibiotics affect the growth of E coli? Hypothesis: If Penicillin is applied to the bacteria‚ then the zone of inhibition will be larger. Background: The purpose of this lab was to see how effective a certain antibiotic is to kill E coli. The lab tested three antibiotics‚ Penicillin‚ Erythromycin‚ and Neomycin. The zone of inhibition‚ which is the amount of space

This report by Wright‚ Seiple‚ and Meyers discusses mainly the history of antibiotics as well as its link to future discoveries. Each section in the report examines different points throughout the essay: 1) The authors suggest chemical synthesis as the key to the development of the first antibiotic. All antibiotics discovered by humans have been categorised into one of the following: natural products (manufactured directly by bacteria)‚ semisynthetic antibacterials (manufactured by chemical synthesis

The Rise of Antibiotic-Resistant Infections by_ Ricki Lewis‚ Ph.D._ When penicillin became widely available during the second world war‚ it was a medical miracle‚ rapidly vanquishing the biggest wartime killer--infected wounds. Discovered initially by a French medical student‚ Ernest Duchesne‚ in 1896‚ and then rediscovered by Scottish physician Alexander Fleming in 1928‚ the product of the soil mold Penicillium crippled many types of disease-causing bacteria. But just four years after drug

30 February 2014 Antibiotic Resistant Bacteria: What is it‚ how to prevent it and who it affects? In the United States alone‚ about 23‚000 people die from antibiotic resistant infections yearly. It is also one of the top 15 most dangerous illnesses in the country (United States House of Representatives). Antibiotic resistance is when bacteria develops a different response to an antibiotic that is its ancestor bacteria. Slight changes in bacteria enable the antibiotic to work and successfully

Biology Research Task- Lucy Kerslake What causes antibiotic resistance? Antibiotic resistance occurs when an antibiotic is no longer effective against a particular bacteria‚ making that organism resistant to the effects of the antibiotic. Bacteria become resistant due to selective pressure. Those organisms which resist the antibiotic‚ and do not die from it ’s effects have a greater chance of survival within the host‚ therefore allowing them to reproduce and spread it ’s resistance to other
