Download file to see previous pages Methicillin resistant S. aureus is an antibiotic resistant form of S. aureus that has emerged as a significant strain of this bacterium. The first outbreak was reported in 1980 in the region of Detroit and since then MRSA has established itself as a clinically dominant community pathogen. In 2004, a study of adult patients who presented with purulent staphylococcal infections in the emergency, MRSA constituted a 78% of S. aureus infections (Crossley et al 272, 275). The community associated MRSA has been defined on the basis of the criteria provided by the Center for Disease Control and Prevention. According to the criteria, infections are classified as MRSA if (a) MRSA is isolated within 48 hours from a hospitalized patient, (b) the patient presents with a history of hospital admission, dialysis, surgery or long term care facility residence, (c) patient has an indwelling device during the time of culture isolation, (d) previous history of MRSA infection (Crossley et al 272). It is important to differentiate the microbiological characteristics of the MRSA strains from the S. aureus, the disease spectrum and manifestations so that a correct diagnosis and treatment plan can be devised. Fig 1 :Prevalence of MRSA shown in relation to the age of the patients performed by the National Health and Nutrition Examination Survey 2001-2004 (Crossley et al 281). The microbiological characteristics of the staphylococcus aureus are significant in understanding the clinical course of the disease. Staphylococci are included in the Gram positive bacteria which are signified by their catalase-positive and facultative anaerobic properties. Staphylococci measure 0.2-1.5 micro-meters in diameter and produce golden yellow colonies on agar or broth cultures within 12-24 hours at 37 C. The colonies are formed in grape like cluster formation or in the form of pairs, chains or even single bacterium (Weston 128). MRSA is a type of S. aureus that is resistant to a group of antibiotics called beta-lactams. This group includes Methicillin and others such as oxacillin, amoxicillin and penicillin (Centers for disease control and prevention n.p.). Fig 2: Representation of the MRSA colonies on the cultures agar observed through microscopic examination (Centers for Disease Control and Prevention n.p.). The epidemiology of MRSA is mostly significant in health-care facilities. MRSA is typically introduced through patients who are transferred from other health care settings. Doctors are also considered as important sources of inter-hospital spread of MRSA infections. Spouses of patients can also act as reservoirs of infections at several times. Colonization occurs rapidly once MRSA is introduced into a hospital. Open wound diseases such as skin diseases including chronic dermatitis, ulcers, burns, surgical wounds and decubitus ulcers predispose the patients to the MRSA colonization. Aged and debilitated patients, patients on poor anti-microbial therapy, intensive-care patients, patients of chronic hemodialysis or long-term hospitalized patients are at higher risks for MRSA infection development (Gantz et al 264,265). Apart from patients in health care facilities, visitors of infected patients are also at high risk. Disease is transmitted through casual contact such as hugging, touching or kissing. Close skin to skin contact or contact of open wounds with contaminated items and surfaces also predisposes to MRSA infections.

Prevent hospital-acquired Methicillin-Resistant Staphylococcus Aureus (MRSA)

... Methodology For the production of a valid and comprehensive research, proper selection of methodology acts as an important device for synthesizing the research topic. From the point of Aveyard (2007) it is known that the application of appropriate methodology can guide the researcher as well as the readers throughout the journey of the research and will help them to come at interesting results. Research is basically bifurcated into two major divisions and they are quantitative research and qualitative research. The process of quantitative research is dedicated towards testing hypothesis; concentrate on the cause and effect relationships and arriving at certain predicted outcomes. In this study a specific number of variables... Methodology...

The Molecular Mechanism That Make Staphylococcus Aureus Resistant To Antibiotics

...? The Molecular Mechanism That Make Staphylococcus Aureus Resistant To Antibiotics ID Introduction, An antibiotic is asubstance that kills bacteria by disrupting a critical function, usually coded by a definite protein in the bacteria. Once this critical function is affected the bacteria cannot carry out its normal functional roles, and it is eliminated from the ecosystem. Antibiotics bind to proteins making them lose theirs capacity to carry out normal functions. Proteins normally replicate DNA, resulting in cell walls for bacteria or proteins for definite purposes. According to Talaro (2006), these processes are extremely vital in the functioning of bacteria. On the other hand, if bacteria develop resistance to antibiotics... is usually...

Staphylococcus Infection

...?Staphylococcus Infection This essay is concerned with staphylococcal infections, in particular those caused by staphylococcus aureus, focusing in particular on urinary tract infections. Included are descriptions of the bacteria, risk factors, treatment and avoidance and control. Also mentioned are the newer, drug resistant strains and the global implications of these. Introduction The bacteria of staphylococcus aureus, one of about 30 different staphylococcal types which can cause human infections, are gram positive, spherical and gather in clusters. They are golden yellow in color and non-motile, tending to form clumps rather like small bunches of grapes. Any testing of material from the human nose, other mucus membrane or skin... one...

Maintaining the pH in Its Normal Levels Prevents the Growth of Methicillin-Resistant Staphylococcus Aureus

...? Maintaining the pH in its normal levels prevents the growth of methicillin-resistant Staphylococcus aureus (MRSA) The Characteristics of MRSA Staphylococcus aureus is a group of lactic acid-producing bacteria commonly found on the surface of the skin. When it penetrates a break in the surface, it induces an immune response that involves hydrogen peroxide and nitric oxide. For example, when it reaches the gut, it induces what is clinically referred to as enterocolitis, or infection of the digestive tract (Suzuki, 1994). Methicillin-resistant S. aureus (MRSA), just like other S. aureus strains avoids such...

Methicillin-resistant Staphylococcus aureus

...?In the workplace, the chronic illness renal disease patients need to go to the hospital and clinic frequently; therefore, the decontamination of theenvironment to prevent cross transmission is most beneficial. Moreover, nowadays, one of the most difficult to treat is Methicillin- resistant Staphylococcus aureus (MRSA). Decontamination ensures that there are no medical or health implications in the treatment process with regard to renal medicine. This is due to the possibility of infections that could hinder or act as counteractive measures towards the entire of treating renal diseases. Moreover, cleaning and decontamination alleviates all forms of erroneous diagnosis and reinfections with unknown pathogens, as well as conditions... such as...

...cocci. They are normally arranged in chains that do vary in their lengths and sometimes are ever in pairs. Several species of this genus are able to grow properly on conventional culture media but their growth can be enhanced on culture media with sterile blood (normally horse or sheep) and in an environment that is aerobic or CO2 enhanced environment. Several of these species are able to grow both anaerobically and aerobically hence known as “facultative anaerobes”. Some streptococci species are obligate anaerobes. Hence Catalase negative. Staphylococcus aureus is a Gram positive non-motile cocci bacterium. It is normally in grape-like (staphylo-) clusters, hence the name...

...Community acquired methicillin-resistant Staphylococcus aureus or al affiliation Community acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) was first recognized in 1960. The disease takes mostly the form of skin and soft tissue infections. In many parts of the world, it is the most common nosocomial bacterial pathogen. In the past, CA-MRSA infections occurred in patients who frequently had contact with health care or in specific group of patients such as intravenous drug users. Currently, CA-MRSA also affects healthy people that have no risk factors for the disease. The etiology of CA-MRSA infections includes presentation...
