The Staphylococcus Aureus Bacterium

For many years the identification of microorganisms has been important in the world of medicine. It is essential or correct disease diagnosis in patients and for proper treatment. Knowing the correct identity and characteristics of microorganism is crucial when disease outbreaks occur in populations, also knowing how humans can benefit

Abstract Staphylococcus aureus is a gram positive bacterium. It is accountable for numerous conditions when it crosses the threshold into the human body. The bacterium may also be referred to as a ‘Staph infection’. There are more than 28 different types of staphylococcus aureus that are responsible for cellulitis, blood poisoning, and various others. Methicillin resistant Staphylococcus aureus is also a type of staphylococcus aureus. Staph infections are curable with different antibiotics.

Candace Byler 9/14/2014 Article Summary #1 Methicillin-resistant Staphylococcus aureus, or MRSA, is a bacterium that is resistant to many available high- level beta-lactam antibiotics, which include penicillins, “antistaphylococcal” penicillins and cephalosporins. Staphyloccoci are the most important bacteria that cause disease in humans. MRSA is sometimes branded as a nosocomial infection as it

Fighting Staph Hospital acquired infections (HAI) are never good. Moreover, according to the Centers for Disease Control and Prevention, one in 25 patients will develop an infection which was procured during their stay in a hospital (Centers for Disease

MRSA stands for Methicillin-safe Staphylococcus aureus. MRSA is a bacteria that is very hard to treat that infections in animals’ and humans body. MRSA was initially reported in 1961 when a researcher found it and the first case was in 1968. It's impervious to a gathering of anti-infection agents which incorporate methicillin and this is the explanation why it's hard to treat. "Staphylococcus" is comprised of two Greek components. The main component, which is "staphule," implies a pack of grapes and the second component "kokkos" means berry. The two Greek components consolidate to frame the current Latin word "staphylococcus." "Aureus" is characterized as golden. Staphylococcus aureus is a circular bacterium yet that is not by any means

Staphylococcus aureus is a gram-positive coccal bacterium, 1µm in diameter, forming grape like clusters or clumps, and is the most important pathogen amongst Staphylococci bacteria. A gram stain was performed on unknown bacteria #41, producing a purple, gram positive cocci bacteria appearing in grape like clusters or clumps under microscope. A streak plate test on nutrient agar was performed resulting in yellowish colonies on the nutrient agar. A catalase test was then performed with a positive Staphylococcus result. Mannitol Salt Agar plate was then used to determine between Staphylococcus aureus and Stapylococcus epidermidis.

Introduction Staphylococcus aureus is a Gram-positive coccal bacterium which is estimated to have colonised 20-30% of the human population.1,2,3 S. aureus is normally found in the anterior nares and mucous membranes of these individuals. For the majority, this is not a problem as these people are colonised, not infected.2,3 However S. aureus is an opportunistic pathogen and if it contaminates a breach in the skin or mucous membranes, it can go on to infect any tissue in the body.3 Infection may lead to serious life threatening diseases such as pneumonia.4 Over time strains of S. aureus were able to develop resistance to antibiotics, resulting in strains known as methicillin resistant Staphylococcus aureus (MRSA).

Staphylococcus aureus is an opportunistic pathogen found mainly on skin, nose and respiratory tract 1 The gram positive facultative anaerobe is round. Transmission occurs through humans or animals, exposure to contaminated surfaces or enterotoxins presence in food 2 . Most susceptible are newborns, young children and the elderly due to reduced immune function 3, 4. Immunocompromised individuals diagnosed ( ie. AIDS, HIV, Crohn’s etc.) assume greater risk of infection 3, 5 . S. aureus causes many diseases including food poisoning, endocarditis, skin/soft tissue (enterotoxin caused scaled skin and abscess) and pleuropulmonary infections (ex. pneumonia), osteomyelitis, septic arthritis and bacteremia 2, 3. In health care settings S. aureus colonies

MRSA is a strain of Staphylococcus aureus that stands for Methicillin Resistant Staphylococcus (Staph) Aureus. Staphylococcus aureus is a gram-positive coccal bacterium that is commonly found in the nose and on the surface of the epidermis of healthy patients, which act as a part of the normal flora, whereas, MRSA can commonly be found on the surface of the skin near the mouth, genitalia and the rectum. (MRSA symptoms, n.d.). MRSA is a specific strain of staph that over time has mutated to become resistant to most antibiotics. MRSA is referred to as being methicillin resistant because that antibiotic, methicillin is the primary antibiotic that is used to treat most strains of Staph aureus and unfortunately this particular strain of Staph, MRSA, is unaffected by its typical antibiotic treatment. MRSA is most commonly acquired nosocomial infection, or more commonly known as a hospital acquired infection. Though it is not as likely, there is a slight possibility of becoming infected with MRSA

Staphylococcus Aureus is a gram-positive bacterium that is most commonly responsible for causing staph infections. Staphylococcus Aureus is derived from the greek word kokkos which means “bunch of grapes.” This is very a very appropriate name for this bacterium because under a microscope it looks exactly like a bunch of grapes.

According to drugs.com, tamoxifen is a synthetic drug, that is used to treat some types of breast cancer in men and women. It is also used to lower a woman's chance of developing breast cancer if she has a high risk (such as a family history of breast cancer). What is

Staphylococcus aureus is a type of bacteria. It stains Gram positive and is non-moving small round shaped or non-motile cocci. It is found in grape-like (staphylo-) clusters. is one of the five most common causes of infections after injury or surgery. It affects around 500,000 patients in American hospitals

Staphylococcus aureus Life History and Characteristics: Staphylococcus aureus is a gram positive bacterium that is usually found in the nasal passages and on the skin of 15 to 40% of healthy humans, but can also survive in a wide variety of locations in the body. This bacterium is spread from person to person or to fomite by direct contact. Colonies of S. aureus appear in pairs, chains, or clusters. S. aureus is not an organism that is contained to one region of the world and is a universal health concern, specifically in the food handling industries.

As antibiotic resistance has become a major concern in public health, multi-drug resistant “Staphylococci.aureus” appears to be the most prevalent pathogen that is responsible for nosocomial infection across the globe and recently labelled as a “Super bug”. Staphylococci are Gram-positive, facultative aerobic microorganisms and present mostly transiently on the skin or anterior nares in approximately 20 to 30 % of healthy adult individuals. Among 30 different types of staphylococci which causes infection in human, Staph.aureus is regarded as one the major pathogen in both medicine and food safety. There is a wide variety of infection caused by Staph.aureus and most of them are skin infections and other includes pneumonia, endocarditis, osteomyelitis,

S. aureus is a normal flora in the nasal cavity Minor infections like boils and pimples are caused by S. aureus. This kind of infection can be treated without antibiotics. The invasive infections are treated by antibiotics. S. aureus have clones (groups of bacteria that are genetically related
