The problems that arise regarding the antibiotic resistance of certain bacteria has continue to worry the health industries. One of these bacteria is the Staphylococcus aureus. It has been one of the major causes of hospital-acquired infections which has resulted to a lot of deaths each year. Description Staphylococcus aureus is a gram-positive bacteria which indicates that it has a cell wall structure with a thick layer of peptidoglycan. It is a facultative anaerobe which allows it to perform

Having the ability to collect and identify unknown microorganisms is vital in health and medicine. This capability is important for a variety of reasons‚ such as knowing the causative agent of disease‚ knowing if the microorganism obtains any beneficial properties and knowing the correct microorganism to use to create a successful antibiotic. Implementing the experimental methods learned thus far in the microbiology laboratory allowed an unknown bacterium to be identified as a result of this study

Methicillin Resistant Staphylococcus Aureus Staphylococcus aureus bacteria‚ commonly known as staph‚ are very common. It is "a spherical gram-positive parasitic bacterium of the genus Staphylococcus‚ usually occurring in grapelike clusters and causing boils‚ septicemia‚ and other infections." In fact‚ many people have some living on their skin all of the time and it can cause infection anywhere in the body. There are antibiotics that have been known to kill this bacterium. Unfortunately

Staphylococcus aureus: From a Spot to the Hospital The hospital is silent this morning‚ as the sun breaks through the blinds and casts off all the silver objects in the room. My hospital bed is uncomfortable‚ and it makes me yearn for my 100-year-old mattress and many unnecessary plush-pillows. The smell of bleach and cleanliness lingers in my nose and almost makes me feel sicker. How did I end up here? Well‚ that is not an adrenaline rushed injury or a freak accident‚ but something that started

Unknown Microorganisms May 1‚ 2013 This paper is based on an experiment done in the laboratory over a period of time using the standard method of identifying an unknown microorganism relying on features such as morphology‚ arrangements and biochemical reactions. It was done in succession with each step complimenting the other. At the end of the experiment three microorganisms Bacillus azotoformans‚ Staphylococcus aureus‚ and Escherichia coli was identified and one result was inconclusive. The

By having a universal method of identifying bacteria allows for all scientists from any part of the world to identify the same species in an identical manner allowing for a precise of classification. Bacteria are distributed throughout the world in almost every conceivable habit. Bacteria are unicellular microorganisms‚ with variable shapes and nutritional needs. They lack a distinct

Methicillin-resistant Staphylococcus aureus September 22‚ 2013 Methicillin-resistant Staphylococcus aureus Methicillin-resistant Staphylococcus aureus also known as MRSA‚ is a bacteria that is resistant to many antibiotics. In the community‚ most MRSA infections are skin infections. In the medical facilities‚ MRSA causes life-threatening bloodstream infections‚ pneumonia and surgical site infections. (Methecillin-resistant Staphylococcus aureus (MRSA) infections‚ 2013) Individuals would

Escherichia coli and Staphylococcus albus Some bacteria’s require a certain amount of light in order to function properly and there fore survive. Escherichia coli is found in the gut and intestines of mammals. Staphylococcus albus is generally a skin dwelling bacteria Aim: To test whether the amount and type of light that the bacteria’s E.coli and S.albus are subject to causes changes in their growth rates and habits. To test whether the growth rates and habits of the bacteria’s E. coli and S

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
