The Misuse of Antibiotics and Bacterial Resistance

Antibiotic resistance is rapidly becoming a major challenge in regard to modern medicine, the rapid reproduction, selection pressures and the advanced evolution of bacterial cells through a series of survival mechanisms has lead to a potentially catastrophic consequence in regard to treatment of human disease caused by bacterial infection, Antibiotic Resistance. The advanced survival mechanisms of bacteria and the increased misuse and lack of understanding with regard to the treatment of bacterial

most importantly, antibiotic misuse needs to be avoided because it can lead to antibiotic resistance. Antibiotic resistance is a bacterium’s ability to overcome the effects of antibiotics and to survive in the presence of them (“About” par. 1). This is what causes antibiotics to be ineffective towards some bacterial infections. When a bacteria is exposed to the same antibiotic regularly, that bacteria mutates to become antibiotic resistant. Bacteria have many mechanisms of resistance. For instance,

Antibiotic resistance is a type resistance of bacterial infection to the drug prescribed by doctors to individuals who are infected. Antibodies that are given to a person may not be enough to cure a bacterial infection due to “superbugs” which is a pathogen resistant to many different types of antibodies. Some of the reasons why this exists is due to common misuse of people in antibiotics. For instance, not finishing up what the doctors prescribe after feeling better and saving for later for future

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

The misuse of penicillin and other antibiotics however is causing the growing problem of antibiotic resistance in which seemingly harmless infections turn to be deadly and dangerous. Antibiotics are not only casually used as treatments for bacterial infections, but are also used in agriculture and veterinary medicine, creating controversy on the proper uses of antibiotics. As advancements in the medical fields proved to be beneficial for a short period of time, today the misuse of these innovations

domestication, breeding, chemical resistance, bacterial resistance to antibiotics and multi-drug resistance. Human actions, especially the use of antibiotics and chemicals have dramatically increased the rate of evolution. This is primarily due to the huge impact humans have in the world through industrialisation, agriculture, medicine and

The article ‘Antibiotic Resistance’ is written by Holden Wright. Holden Wright has a degree in Pharmacology and is currently working in the Pathology Department at St. Thomas Hospital. This article is written because of the increasing emergence of antibiotics resistant bacteria. Antibiotics and similar drugs are called antimicrobial agents, have been used for the last 70 years to treat patients who have infectious diseases. These antibiotics may either kill or inhibit the growth of bacteria. These

The original success of antimicrobial agents has had a large influence over America’s dependency of antibiotics. Originally, these agents were widely considered as a cure-all drug by many involved in the health field and by the Americans receiving these medications. Such medical breakthrough won alexander Fleming, the creator of penicillin, a Nobel Prize in 1945 (“Antimicrobial Resistance: Global Report”) Regardless of the beneficial properties his vaccination, he warns that improper use can be followed

Antibiotics are powerful very frequently used potential drugs in fighting bacterial infections worldwide, [1]. These agents saved millions of lives in the past fifty years in both hospital-based and outpatient settings. Inadequate measures to control the spreading of infections, overprescribing as well as inappropriate selection and dosing of antibiotics by healthcare providers, unfettered access to antimicrobials by public, failure to adhere to clinically desired treatment regimens are some of the

previously discussed, antibiotics often work by targeting critical functions of the bacterial cell. This means that antibiotics have specific targets, which is a boon because it means non-microbial life will not be affected by the antibiotics. However, because of this specificity, bacteria can develop ways of protecting themselves from antibiotics, leading to the rise of antibiotic resistance Like any other organism, bacterium are subject to evolutionary pressure. Antibiotic resistance in bacteria is rarely
