Antibiotic resistance In recent years a challenge to the effective treatment of an ever-increasing range of infections caused by microbes is antimicrobial resistance (AMR). AMR results in reduced effectiveness of antibiotics‚ making the treatment of patients very difficult and sometimes impossible. The impact on especially susceptible patients is most evident‚ resulting in prolonged illness and increased mortality. The total problem caused by AMR on medical field in general and healthcare sector

Name: Yao Xu Class: F Date: 9/20/13 Penicillin Penicillin‚ discover by Sir Alexander Fleming in 1928‚ is a type of antibiotics that can slow down the growth of bacteria or to kill them. Penicillin only affects on bacteria and it doesn’t help with the infection of virus. Penicillin is divided into two groups: natural penicillin and man-made penicillin (Lowe D. 2012). During World War II‚ penicillin saved a lot of people in Europe. The first person saved by penicillin was a nurse named Anne

Why are people worried about it? ntibiotic resistance is the effect of antibiotics on germs that infect our body. Most of the antibiotics have lost their A resistance to fight germs. People are worried about it because if antibiotics won’t work no longer than we could even die from a paper cut. 2. How can antibioticresistant germs travel from people out into the environment

Abstract The spread of antibiotic resistance is a universal threat to both humans and animals for treatment of microbial infections. The antibiotic resistance is generally not preventable but can still be controlled. Prolonged and repeated use of antibiotic leads to many pathogen becoming resistant to antibiotics. The resistance may be either intrinsic or acquired depending on the condition. Although classically attributed to chromosomal mutations‚ resistance is most commonly associated with

The advantages and disadvantages of Antibiotic usage in Humans Since the discovery of antibiotics and their usefulness in therapeutic interventions‚ they have risen to prominence owing to their ability to improve the quality of life through the treatment and management of a wide array of diseases of bacterial aetiology. An Antibiotic is a compound or substance that kills or slows down the growth of bacteria. Antibiotics are powerful drugs for disease management making

Antibiotics research 1. Define the term antibiotics Antibiotics are a drug used to treat infections caused by bacteria and other microorganisms. Originally‚ an antibiotic was a substance produced by one microorganism that selectively inhibits the growth of another. Synthetic antibiotics‚ usually chemically related to natural antibiotics‚ have since been produced that accomplish comparable tasks 2. a) who was the first scientist to discover antibiotics Alexander Fleming (1928) b) Briefly

He was completely oblivious to important aspects of antibiotics including their ineffectiveness on viruses and the potential harm that would be caused by their overuse. Although at the time antibiotics seemed to be the remedy for almost any infectious disease‚ this was not the case. Doctors continuously prescribed antibiotics for almost

understand the interaction between bacteria and antibiotics better. Such great understanding would then allow for manipulation of the drug usage‚ thereby strengthening our understanding of how to optimise antibiotic performance. Over the past decade‚ there have been numerous occasions where researchers have successfully identify possible pharmacodynamic outcome predictors‚ and assign quantitative values that would enable prediction of success/failure of antibiotic regimens. Furthermore‚ after reading this

commonly used antibiotics is constantly increasing. Bacteria particularly dangerous for human life are methicillin-resistant Staphylococcus aureus‚ vancomycin-resistant Enterococcus faecium and fluoroquinolone-resistant Pseudomonas aeruginosa. Hence‚ there is an incessant need for developing compounds with new modes of action and seeking alternate drug targets. In this review‚ the authors discuss the current situation of antibacterial medicines and present data on new antibiotic targets. Moreover
