Methicillin-resistant Staphylococcus aureus, or more commonly, MRSA, is an emerging infectious disease affecting many people worldwide. MRSA, in particular, is a very interesting disease because although many people can be carriers of it, it generally only affects those with a depressed immune system; this is why it is so prevalent in places like nursing homes and hospitals. It can be spread though surgeries, artificial joints, tubing, and skin-to-skin contact. Although there is not one specific treatment of this disease, there are ways to test what antibiotics work best and sometimes antibiotics aren’t even necessary.

Describe methicillin resistant Staphylococcus aureus (MRSA) and its implications for patients who are diagnosed with this.

Staph are common bacteria that are denizens of the human body. It is perfectly fine to carry staph; a lot of healthy people hold it within their bodies without being infected by it. Furthermore, one third of the population has staph bacteria in their noses. However, staph can rapidly become quite a problem if it manages to enter the body, usually through a cut, and cause an infection. Staph is one of the most popular causes of skin infections in the U.S. Most infections are minor, not fatal, and don’t require special treatment, but some can be disastrously life-threatening, creating festering wounds or pneumonia.

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 usually plagues patients that are receiving treatment in a hospital. The skin is the most common site of infection, where MRSA can cause cellulitis, folliculitis, or boils in the skin, but can also commonly be found in the nose, underarm, groin, upper respiratory tract, intestine, vagina and rectal areas of the body. MRSA infections occur with there is a break in the skin that allows the Methicillin resistant

Staphylococcus aureus, a microorganism, is the leading cause of today’s infection in the hospital setting in the US. The optimal growth conditions consist of moist, warm, dark environments. On humans, it is usually found in the nares, groin, and axilla. In 1941, the antibiotic penicillin was discovered and was used to treat S. aureus infections. This

Methicillin-resistant staphylococcus also referred to as MRSA is a type bacterium that becomes immune to many antibiotics used to treat even the most common infection. MRSA has become an issue in hospitals around the globe as it is known to constanly change over time. Methicillin-resistant staphylococcus (MRSA) usually occurs in day care home, hospitals and other related health care facilities. It was reported that in 2005 the majority of all infection related cases came from an antibiotic-resistant bacterium, resulting in a high rate of death (Tacconelli, et al 2007). In 1961 (Enright, et al 2002) methicillin-resistant staphylococcus (MRSA) was first discovered in the United Kingdom and later made its way to Asia and after to the United States.

Methicillin-resistant Staphylococcus aureus, or MRSA is a source of major concern for public health. MRSA is no longer a sole property of inpatients’ infections, but spreads quickly in the community, responsible for more deaths in the US than AIDS. It demonstrates increasing prevalence not only among people with weak immune systems, but also among those who we consider to be the healthiest.

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

The occurrence of hospital acquired infections has become a norm in the health care system. Patients’ experiences of being infected with MRSA at a hospital and subsequently isolated follows 6 patients in their experiences after becoming infected with methicillin- resistant staphylococcus aureus (MRSA) in an outbreak in Sweden. MRSA this is a staphylococcus bacteria that has become resistant to antibiotics such as penicillin, which was traditionally used to treat it (Vyas, 2015).

MRSA alone kills more people in the US every year than homicide, HIV/AIDS, Parkinson’s disease, and emphysema combined” (para. 1).

Before the turn of the 21st century, physicians across the country were realizing that the possibility of being able to treat and cure virtually any microbial infection with the use of a single or a combination of antimicrobial medications was becoming more and more of a challenge. In the late 1960s and early 1970s, reports of pathogenic resistance to even the most potent antimicrobial medications of the time were being sent to the Centers for Disease Control. Among even the most dangerous pathogens that have developed and are developing drug resistance to one or many antimicrobials, Staphylococcus aureus (S. aureus) is perhaps a case in which the world is most familiar and of the greatest concern within the medical community due to its natural virulence-its ability to cause a multitude of life-threatening infections, and its above average ability to combat and adapt to a vast array of environmental conditions.

According to the National Institute of Allergy and Infectious Diseases (NIH) Staphylococcus Aureus (S. Aureus) was first discovered in the 1880s. The S. Aureus infection caused pain on site, boils, and scaled skin. The S. Aureus infection can cause bacterial pneumonia or bacteria in the blood stream which can have fatal effects. In the 1940s the use of the antibiotics such as penicillin became a routine treatment for the infection. The consistent treatment using antibiotics lead to the bacteria evolving and becoming resistant to the drugs that were fighting the bacteria. In the late 1950s scientist developed methicillin, which is a form of penicillin,

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.

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), which confers resistance to beta-lactam antibiotics and is encoded by the mecA gene on the mobile element, staphylococcal cassette chromosome mec (SCCmec). There are a variety of methods in diagnostic microbiology laboratories to identify

The discovery of antibiotics is arguably the greatest contribution to modern medicine. The widespread use of antibiotics along with vaccines had paved the way for the treatment and cure for many of the otherwise fatal bacteria diseases and this led to a decline in the mortality rates in the mid-20th century. The use of antibiotics in medicine today to treat diseases have not all been met with positive outcomes. As a matter of fact, its relative ease of access and abundance has given rise to a major problem in creating new strains of bacteria that are able to resist our antibiotics today. Such is the case for a special type of bacteria, Staphylococcus aureus, a gram-positive bacterium with a spherical shape which in some strains of this particular species has ultimately developed resistance to virtually all antibiotics we have present today. Staphylococcus aureus is often found on skin surfaces in humans colonizing about 30% of the human population [1]. They generally are not pathogenic until they enter inside the body through an open wound or colonize other areas of the body of which they generally are not found [1]. Staphylococcus aureus commonly cause non-fatal skin diseases such as folliculitis, cellulitis and abscesses however, they can invade the circulatory system and cause a serious infection known as bacteremia [1,9]. Bacteremia is often common in a hospital setting where patients are exposed to invasive procedures such as surgeries which allow colonies of S.
