But that doesn’t stop people from trying. In 2010, the American College of Physicians estimated that of the more than 133 million courses of antibiotics prescribed in the United States each year, as many as 50% are prescribed for colds and other viral infections. What’s more, many patients who are prescribed antibiotics for bacterial infections use them improperly. Taking only part of a prescribed dose, for example, can spare some harmful bacteria living in the body, and those bacteria that survive are often heartier and more resistant to the antibiotic than the ones that were killed. Such overuse and misuse of antibiotics have led to an epi- demic of such antibiotic-resistance, which the Centers for Disease Control and Prevention calls “one of the world’s most pressing public health problems.”…
Etiology- MRSA is caused by Staphylococcus aureus germs on the skin that start an infection in a surgical wound or open wound. Unnecessary use of antibiotics have, over time, increased the resistance of the germs to the antibiotics used to treat them.…
To understand Methicillin-Resistant Staphylococcus aureus, we must first understand Staphylococcus aureus. Staphylococcus aureus is a spherical, or coccus, bacteria (MRSA). The bacteria usually appears is chains, bunches, or grape like clusters, (Gregory, 229). It is a gram-positive aerobic organism that causes skin infections and sometimes pneumonia, endocarditis and osteomyelitis (Beers, 1442). This infection commonly leads to abscess formations (Beers, 1442). Staphylococcus aureus is a coagulase positive bacterium, and is among those that are dangerous human pathogen because it has the ability to both be extremely virulent and its ability to develop antibiotic resistance, (Beers, 1442).…

Staphylococcus aureus (S. aureus) was first discovered in the 1880s and is a dangerous and versatile pathogen that causes many types of severe diseases. Most commonly it causes skin infections, respiratory tract infections, and food poisoning. In the 1940s, when the antibiotic medications such as penicillin was discovered and introduced, it became a primary treatment for S. aureus infections. However, misusing and overusing the use of antibiotics caused the evolution of these bacteria to become resistant to drugs that were designed to combat these infections. Throughout 1950s, S. aureus became resistant to penicillin, so methicillin was introduced to counter the growing populations of penicillin-resistant S. aureus. In 1961, the first strains of S. aureus bacteria became resistant to methicillin and so the methicillin-resistant S. aureus (MRSA) was born. Since methicillin is a form of penicillin, the MRSA are resistant to an entire class of penicillin-like antibiotics called beta-lactams. S. aureus continues to evolve and have shown more resistance to additional antibiotic drugs over time (NIH, 2008).…
By definition methicillin-resistant staphylococcus aureus (MRSA) is a bacterial infection that is highly resistant to antibiotics. Staphylococcus aureus is a strain of bacteria that is normally found on the skin or in the nasal passage way of about one third of the population. MRSA is the staphylococcus aureus bacteria that do not respond to antibiotics.…
Innovation and technological advancement are two reasons why humanity has come so far from its origins. However, could one of mankind’s breakthroughs lead to its downfall? Sickness has its place in history as one of the most prolific killers of people. The Black Plague in the Middle Ages wiped out significant human populations. In the present, research in medicine has brought forth antibiotics – a way of stopping harmful bacteria from infecting a person. Growing concern is centered on the fear that the overuse of antibiotics will create different types of “super bacteria”, or bacteria resistant to multiple kinds of antibiotics.…
Superbugs are becoming a big problem in the world, but what are superbugs? Superbugs is a bacteria that becomes resistant to antibiotic drugs they carry genes that are resistant to antibiotic drugs and cannot stop the bacteria from multiplying (Staff 1). You might know of superbugs by the term multidrug-resistant bacteria. This mostly happens when people overuse antibiotics and their body becomes immune to those drugs. In very severe cases people with extremely weak immune systems usually die if they catch the superbug because it basically takes over their body (Stueck 1). Any species of bacteria can become a superbug, and are most common in older people in nursing homes or hospitals because that is when their immune systems are the weakest (McCall 1).…
Finally, if the patient is prescribed antibiotics, he or she must be responsible and complete the entire prescribed course of antibiotics. This will prevent the production of resistant “super bugs” and prevent the need for new antibiotics to be created. In order for the supply of antibiotics to decrease the demand for it must first decrease, unless proper knowledge and effective practices are utilized this antibiotic problem will persist.…
The consequences of the antibiotic crisis can be slowed down or even stopped, but only if aggressive steps are taken and are actually followed.…
