Antibiotics use is as popular as ever with American people today. Every day over 190 million doses of antibiotics are administered in hospitals and more than 133 million antibiotic prescriptions are written out to non-hospitalized patients every year (4). These staggering numbers have made many skeptics question the effectiveness of these antibiotics and the frequency in which doctors prescribe them. Antibiotics are not a one stop cure for all illnesses. In fact‚ antibiotics are only effective

tics Antibiotics Several scientists around the beginning of the 20th Century discovered substances that were toxic to bacteria yet not to the human cell. But it wasn’t until Sir Alexander Flemings own discovery in 1928 that everyone took notice. While washing his equipment‚ Sir Fleming noticed a bit of mold attacking a patch of bacteria. It’s frightening to consider how many more people would have died in the 20th Century if Sir Fleming did not have good eyes. Today‚ some complain that

While we often look at it as a time of bad and wrong decisions‚ there were many positive things that came from them. The most prominent of them were the number of discoveries and inventions that took place and were of great benefits then and now.

The Problem of Antibiotic Resistant Bacteria in Hospitals. Introduction Antibiotic resistant bacteria are bacteria who can survive after exposure to one or more antibiotics. Some bacteria present today can even be resistant to multiple antibiotics and these are sometimes referred to by the name Multidrug resistant (MDR). Today many clinically important bacteria are MDR’s and this is a direct result of past decades of antimicrobial use and misuse. If an infection results from this sort of resistant

Lab Report: Antibiotic Evaluation by the Kirby-Bauer Method Introduction Chemical antimicrobial agents are chemical compounds capable of either inhibiting the growth of microorganisms or killing them outright. Those which are taken internally to alleviate the symptoms of or promote healing from disease are called chemotherapeutic drugs‚ and among these is a class of compounds called antibiotics. In order for a chemotherapeutic drug to be classed as an antibiotic‚ it must be produced by
