Methicillin-Resistant Staphyloccus Aureus (MRSA)
Methicillin-Resistant Staphylococcus aureus
(MRSA)

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). …show more content…
The particular pathogen is cross-resistant to all Beta-lactams, including all penicillin and cephalosporin (Beers, 229). As of late there have been two different way that MRSA has been classified. The first CA-MRSA, is community acquired MRSA, and HA-MRSA healthcare acquired MRSA (Gregory, 230). Both cause skin and soft tissue infections, which include abscess, furuncles, and boils. Most patients do not even notice the site at first claiming they thought it was a spider bite and leave it untreated for an extended length of time (Gregory,

    The genus Staphylococcus includes more than 20 species as described in Bergey 's Manual (2001). Only two are significant to humans, Staphylococcus aureus and Staphylococcus epidermidis. S. aureus colonizes mainly the nasal passages, but it may be found regularly in the oral cavity, gastrointestinal tract and the skin. Staphylococcus epidermidis is an inhabitant of the skin. Of these two Staphylococcus aureus is serious pathogen. Staphylococcus epidermidis is of the normal flora and is not considered to be a serious pathogen (textbookofbacteriology.net). Staphylococcus epidemidis becomes pathogenic when the skin is broken or through contamination from medical procedure. Staphylococcus aureus are only able to invade via broken skin or mucous membranes.…

Until this day, average estimation of 20% of the human population are carriers of Staphylococcus aureus. Staphylococcus aureus, one of the members of the Firmicutes, is commonly found in the respiratory tract or on the skin, causing skin irritation and infection and also sinusitis and respiratory infection (Ogston A 1984).…

    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).…

    An infected area may become red, swollen, filled with pus, very warm to touch, and extremely painful. MRSA infections generally present themselves on the back of the neck, the legs, buttocks, and groin. Although these are the common areas for MRSA to form, it can develop on any area of the body. If left untreated, a MRSA infection will increase in size and possibly spread over the body. The infection can also become so infected that it requires surgical drainage or removal of tissue. If MRSA is acquired invasively, it can become so severe that sepsis, necrotizing fasciitis, and even death can become…

    diff). Clostridium difficile is a type of bacteria that lives in your intestines. It generally will do no harm to the human body but, certain things can lead to this bacteria to grow, which will end up causing some serious life threatening problems. "Most people who get a C. diff infection are getting medical care. The biggest risk factor is taking antibiotics. While antibiotics may cure the bacteria that are making you sick, the drugs can also knock out the healthy bacteria in your digestive tract. Then C. diff takes over." says webmd.com. As of 2011 C. diff was the cause of half a million infections in the United States.There are other bacterial infections that have a serious threat such as Multidrug-Resistant Acinetobacter and MRSA. Multidrug-Resistant Acinetobacter is a bacteria that are mostly found in either soil or water. It has the possibility of living in human skin for days at a time. The people that are mostly seen with this bacteria is the people who have been in the hospital with another illness for a while. This infection is very dangerous because it is faster at developing more resistance against antibiotics than any other bacteria. On the other hand MRSA is a bacteria that stands for methicillin-resistant Staphylococcus aureus. As stated by mayoclinic.org "infection is caused by a…

    S. Aureus

    Staphylococcus aureus is a common human pathogen infamous for its versatility among antibiotics. It colonizes human skins and nares and causes infections when the host’s immune system is weakened. The infection can be acquired in both community and clinical settings, and the frequencies of staphylococcal infections have increased steadily, with little change in overall mortality (Lowy, 1998). S. aureus is incredibly versatile; it has shown to build resistance against antibiotics in a short period of time. For example, the penicillin-resistant strain of S. aureus appeared within 4 years after the introduction of penicillin G into clinical use in 1941. Also, methicillin-resistant Staphylococcus aureus (MRSA) was discovered within the same year…
