S. Aureus Research Paper

Humans are a natural reservoir for S. aureus, and asymptomatic colonization is far more common than infection. Young children tend to have higher colonization rates, probably because of their frequent contact with respiratory secretions.

Staphylococcus aureus is the leading cause of skin and soft tissue infections, it can cause serious infections such as bloodstream infection, pneumonia or bone infections. Though it can cause infections it is part of the normal human flora it is mostly found on the skin or in nasal cavities. It is a facultative anaerobic gram positive cocci, it is usually in pairs or clusters. The bacterium is also catalase positive, oxidase

Staphylococcus aureus (S. aureus) is a spherical bacteria which is known to produce a cytotoxin called Panton-Valentine leucocidin (PLV) which destroys leukocytes, and kills tissue (Lina et al., 1999). Five percent of strains of Staphylococcus are known to produce the disease-causing toxin (Lina et al., 1999), but though the amount of PLV-producing strains is somewhat small, the strains which produce PLV are apparently resistant to vancomycin, an antibiotic commonly used to treat staph infections (CDC, 2002). The first recorded case of S. aureus resistance to vancomycin was a reduction in sensitivity to the antibiotic observed in Japan, and has since spread to the United States (CDC, 2002). The most common source of infection of these drug-resistant bacteria are actually in hospitals, wherein the patients are exposed to the bacteria and subsequently infected (CDC, 2002).

Staphylococcus aureus is a cluster bacterium that can be found on the skin of around 25% of healthy adults. This bacterium is growing everyday all over the world and many people have no idea they are even carriers. “Staphylococcus aureus is present in the nose of adults (temporarily in 60% and permanently in 20 to 30%) and sometimes on the skin” (Levison). This bacterium has the ability to cause skin infection and sometimes may lead to severe life threatening diseases. There are several different strains of staphylococcus and depending on the severity of the infection is how a health care provider decides the treatment most efficient. Impetigo is more common in children, but adults still have the chance of getting this skin condition. Toxic Shock Syndrome is also associated with S. aureus and is found in at least 50% of the cases to date. S. aureus can display a variety of symptoms and all vary with the disease at hand. Symptoms can range from a boil on the skin or in the nose to skin rashes. More severe symptoms can be carbuncles and infection of the blood (sepsis).Staphylococcus aureus is an ugly bacterium; that can lead to several diseases, such as Toxic Shock Syndrome and Impetigo. S. aureus has multiple symptoms and is treated with a variety of antibiotics.

Staphylococcus aureus is a specific type of bacteria which is a member of the Staphylococcaceae family (Medical News, 2016). The bacteria is found in clusters (staphylo-) which look like grapes and as a result is called Staphylococcus. Staph is Gram positive (which is a method for identifying bacteria) and is non-moving (Medical News, 2016). It can infect all mammalian species and because it can infect such a broad range of mammals it is easily transmitted from one species to another species. Of special concern is methicillin-resistant staphylococcus aureus (MRSA) which does not respond to antibiotics.

In our world we are surrounded by microorganisms, some are harmless, many are beneficial; they are a part of our normal flora on our skin and in our intestines, providing a barrier against microorganisms that may not be so harmless. It is important, however, to distinguish which microorganisms are potentially pathogenic from those that are not, and when someone does get ill to determine what the organism is so appropriate treatment can be determined.

MRSA which is short for Methicillin Resistant Staphylococcus Aureus is a staph or skin contamination that is resistant to a part of the most grounded anti-toxins. At the point when Methicillin Resistant Staphylococcus Auereus was initially found a few years prior when it spread in many healing centers and after that into the group, this contamination was known as one of the primary diseases to be resistant to the most effective anti-microbials. Staph contaminations have been referred to following the mid twentieth century as one of the deadliest infections. Staphylococcal contaminations are maladies brought about by various staphylococcal microscopic organisms. Twenty to thirty percent of all sound people get this contamination in the

A total of 88 S. aureus were isolated from different samples including surfaces (n=34, 38.9%), personnel (23, 26.6%), air (20, 23%) and patients (11, 11.9%).

The bacteria is not pathogenic on its own, however produces protein-toxins indirectly, disrupting the host. The bacteria mainly affects the respiratory system of the nose, causes dermal infections. This is one of the most common infections found in hospitals, which is spread by healthcare workers acting as carriers for Staphylococci aureus. Staphylococci aureus has a thick cell wall, making it hard for a body’s immune system to destroy it, and has become commonly resistant to antibiotics, leaving a need to newer generations as it evolves

Methicillin-resistant Staphylococcus aureus (MRSA) is a harmful and virulent antibiotic resistant bacterium that is a major concern in most American hospitals. Modern scientists are aiming to discover effective prevention methods for MRSA in hospitals, so productive prevention guidelines can be created. Clinical microbiologists such as K. Nguyen, J. Cepeda, and M. Struelens all conducted clinical trials in separate American hospitals. They employed different MRSA inhibition techniques, such as hand hygiene, isolation, and MRSA screenings, which were tested on a wide

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 a leading cause of human bacterial infections worldwide1, and following the discovery and widespread utilization of antibiotics, S. aureus has evolved to become resistant to a number of antimicrobial treatments. Most notably, Methicillin-resistant Staphylococcus aureus (MRSA) strains have acquired the mecA gene, encoding the penicillin binding protein (PBP2a), which confers resistance to oxacillin and all β-lactam antibiotics 2. These characteristics, combined with other virulence factors, have made MRSA infections difficult to treat, and lead to MRSA being recognized as a significant cause of morbidity and mortality 3. MRSA is also the leading cause of nosocomial infections4–6, contributing significantly to increased healthcare costs 7. CDC estimated in 2008 that MRSA was responsible for 89,785 cases of disease, causing 15,249 deaths in the US8.

Staphylococcus Aureus is a gram-positive bacterium that is most commonly responsible for causing staph infections.

More than often this microorganism are passed to the individual by a facilitated hospital, which gives rise to the great importance in the study of this bug and particular strains(Espedido). For students that aspire to be part of the healthcare field they will deal with Staphylococcus often and should identify thoughts that are carriers, transmitters, and infected by this bacteria with ease (Kiser 67). Notably, within twenty minutes of a baby being born Staphylococcus has already taken space on the skin, and throughout the course of life everyone will at some point be effected by this super bug. The uniqueness of this bacterium has many virulent factors, it could be caused by an alteration in own bacteria DNA, exposure, transmission, infections among many other ways to bring hostility to one’s life (Tristan). As the years progress, so has medicine; nevertheless, shown in a recent article relating to the resistance of Staphylococcus aureus, more and more people are being infected and die

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.
