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

Unknown #1 Vomit Serratia marcescens & Bacillus cereus Biol 251 Microbiology 5/14/2009 Introduction The purpose of this study is to differentiate and identify two unknown organisms provided by the instructor in a nutrient broth. It is only known that the two organisms are from vomit; one is gram-positive and the other is gram-negative. It is necessary to first separate the two organisms by inoculating a nutrient agar plate using the streak-plate method. The

Introduction Although bacteria is microscopic in size‚ it is largely important in the healthcare field‚ environmental work‚ food preparation‚ as well as many other industries. In particular‚ it is essential that healthcare workers be able to identify the species of bacteria invading a human reservoir in order to prescribe the correct antibiotic that will kill that species. For the purpose of bacteria identification‚ numerous tests have been devised to find out the exact species in question. However

History of microorganisms’ discovery Anton van Leeuwenhoek was the one of the first people to observe microorganisms‚ and used a microscope of his own design‚ and made one of the most important contributions to biology. [18] Robert Hooke was the first to use a microscope to observe living things; his 1665 book Micrographia contained descriptions of plant cells. Before Leeuwenhoek’s discovery of microorganisms in 1675‚ it had been a mystery why grapes could be turned into wine‚ milk into cheese

GRIMONT Introduction The genus Enterobacter was first proposed by Hormaeche and Edwards (1960a). However‚ the history of some species now placed in the genus Enterobacter can be traced‚ albeit with some confusion‚ to the end of the 19th century. “Bacillus lactis aerogenes” was isolated by Escherich (1885) from milk

Introduction Microorganisms are able to carry out different biochemical activities with the ease of different enzymes. Each of these enzymes carries out one specific type of the chemical transformation. They convert substrates into product. A) Carbohydrates Fermentation Microorganisms utilize various carbohydrates

Life beyond Earth does exist. The life that exists beyond Earth is only simple microbial life. In order for complex life to exist many specific events would have had to happen which is highly unlikely. Spacecrafts have found regions of other planets that appear to be able to sustain simple life. Simple life forms have been found on Earth in extreme conditions never thought possible. On someplace other than Earth simple life forms do exist. If complex life were to occur on places other than

c) In what ways did the understanding of the treatment of disease change in the years 1860-1945? The treatment of disease changed dramatically in the years 1860-1845 due to the changes of how people understand it‚ how each discovery such as Pasteur’s opens new doors‚ leading to other discoveries such Koch’s identification of germs‚ the magic bullet and discovery of penicillin. this has help society to understand the causes of disease‚ and the ways to tackle it. These discoveries began in
