Staphylococcus Aureus Essay

Methicillin Resistant Staphylococcus Aureus Staphylococcus aureus is an important and common pathogen in humans. It is found in the nose or on the skin of many healthy, asymptomatic persons (i.e., carriers) and can cause infections with clinical manifestations ranging from pustules to sepsis and death. Most transmission occurs through the contaminated hands of a person infected with or carrying S. aureus. MRSA infections frequently are encountered in health-care settings (Lowy, 1998). A common

Janice was seen in the Infectious Diseases Clinic on December 4, 2013. As you recall, she was being treated for a very complicated methicillin-sensitive Staphylococcus aureus infection which was multifocal in nature. She had several skin lesions including a carbuncle on the right lower leg, a septic right knee and a large subpectoral and subdeltoid collection on the left. Despite a history of penicillin allergy she was given a staged challenge with cloxacillin and tolerated this well. She has been

Staphylococcus aureus was first identified by Sir Alexander Ogston in 1880, although Friedrich Julius Rosenbach is credited with giving the bacterium its current name in 1884. Staphylococcus aureus is commonly considered a natural inhabitant among the microfauna that is found on a human’s skin, inside the nostrils, and inside the lower reproductive tracts of healthy women (Kluytmans et al, 1997). Although S. aureus is commonly found on humans, it is known to be pathogenic, causing a range of illnesses

LABORATORY TESTING OF METHICILLIN RESISTANT STAPHYLOCOCCUS AUREUS 36.512 Medical Bacteriology   INTRODUCTION Methicillin resistant Staphylococcus aureus (MRSA) is a major cause of hospital acquired and life-threatening infections. It has also emerged recently as a cause of community-acquired infections. MRSA strains were first detected shortly after the introduction of methicillin in the early 1960s. Methicillin resistance in staphylococci is mediated by an altered penicillin-binding protein (PBP2a)

Staphylococcus aureus is bacteria species characterized by its golden color and round shape (Lowy, 1998). The bacteria can cause small skin infections or severe infections in vital organs. Infections are most common in the hospital setting. S. aureus has developed resistance to antibiotics in the form of methicillin-resistant S. aureus (MRSA), which displays strong virulent factors and exemplifies the need for novel medications to treat bacterial infections. Current research has examined several

Article #5 In a study Herrmann, Petit, Dawson, Biechele, Halfmann, von Müller ... and Gärtner (2013) conducted a widespread screening in the admission of patients to hospitals for methicillin resistant Staphylococcus aureus (MRSA). The purpose of this study is to show that to help control the spread of MRSA in hospital by having admission prevalence screenings. MRSA is a major nosocomial infection in hospitals and has become a problem that can be hard to manage in patient safety. There are certain

Matthew Crane Lab Section: 13151 Comparative Analysis of Antibiotic Growth Suppression of Staphylococcus Aureus Introduction Staphylococcus Aureus is a gram negative bacterium that may be pathogenic or exist as a commensal organism in humans. Unevolved strains are susceptible to nearly all antibiotics (Chambers & DeLeo, 2009). Among the many antibiotic options, penicillin is particularly effective against S. Aureus. This is due to the mechanism of action by which penicillin replaces key structures in

MRSA stands for methicillin-resistant Staphylococcus aureus and was founded in the 1960’s. It was not recognized until the 1990’s when there was a breakout in the hospitals. Healthcare professionals became frightened of this “Super-Bug” mainly because of the spread from one person to another. It became uncontrollable and staff were not aware of how to prevent the spread and treat the patients. It was then that the hospitals and nursing homes developed infection control measures in order to control

I. Introduction 1. Staphylococcus aureus is a bacteria that can be found on the nose and other respiratory areas, present in about one-third of the population. ‘Staphylococcus’ comes from Greek language, translating into “cluster of grapes” to describe the spherical berry shape of the bacteria and ‘aureus’ translates to “gold” in Latin. That being said, Staphylococcus aureus is golden in nature. When stained and observed under a microscope, it retains a dark purple color and is known to be Gram-positive

Staphylococcus aureus is a bacterium mainly found on the skin and the human respiratory tracts.1 This bacterium is the cause of skin infections like boils and pimples, infections of respiratory tracts (sinusitis) and food poisoning.2 First identified in 1880 as pus from a surgical abscess, Staphylococcus aureus was treated with penicillin which was a “magic drug” when first introduced during the Second World War. Some of these bacteria then evolved, to be resistant to penicillin. Due to this, doctors
