Introduction

MRSA is a serious infection that can become life-threatening if left untreated.

Some germs that commonly live on the skin and in the nose are called staphylococcus or "staph" bacteria. Usually staph bacteria don't cause any harm. However, sometimes they get inside the body through a break in the skin and cause an infection. These infections are usually treated with antibiotics. When common antibiotics don't kill the staph bacteria, it means the bacteria have become resistant to those antibiotics. This type of staph is called MRSA (Methicillin-Resistant Staphylococcus Aureus).

Anyone can get MRSA. Infections range from mild to very serious, even life-threatening. MRSA is contagious and can be spread to other people through skin to skin contact. If one person in a family is infected with MRSA, the rest of the family may get it.

MRSA was first identified in the 1960's and was mainly found in hospitals and nursing homes. This occurred because antibiotics were being given to people when they were not needed, and patients were not taking antibiotics as directed. This type of MRSA is referred to as HA-MRSA (Healthcare-Associated MRSA). In the late 1990's, a new type of MRSA was identified. This new type is referred to as CA-MRSA (Community-Associated MRSA). This new type of MRSA is becoming more common among children and adults who do not have medical problems.

Epidemiology

Recent reports of strains of methicillin-resistant Staphylococcus aureus (MRSA) isolated from children in the community have led to speculation that the epidemiology of S. aureus is changing. Epidemiologic features of the cases described in these reports show a major departure from features typically associated with MRSA colonization or infection. Traditionally, MRSA infections have been acquired almost exclusively in hospitals, long-term care facilities, or similar institutional settings.

Risk factors for MRSA colonization or infection in the hospital include prior

    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.…

    The objective was to compare molecular and phenotypic characteristics between colonization and clinical isolates according to population and individual levels, and markers that could be indicatory of livestock origin. Samples were collected from patients through routine nasal cultures; patient wound sites, and bodily fluids. During the time of screening, all patients were screened for MRSA upon hospital admission, unit transfer, and discharge. According to Kolendi (2010) mecA , a gene found in bacterial cells, allows bacteria to be resistant to certain antibiotics. The mecA gene does not allow the ring-like structure of penicillin-like antibiotics to bind to enzymes that help form the cell wall of bacterium (transpeptidases), so the bacteria continues to replicate normally. The gene encodes the protein known as PBP2A (penicillin-binding protein 2A). PBP2A has a low affinity for beta-lactam antibiotics, such as penicillin and methicillin. This action enables transpeptidase in the prescence of beta-lactams. It prevents inhibiting cell wall synthesis. MRSA is the greatest carrier of mecA gene, and therefore this isolate was given preference for testing. The samples obtained were collected on blood agar plates and then further tested for MRSA on polymerase chain reaction (PCR). MRSA samples were stored at -80 degrees at ICVAHCS until September 2013. All the samples that tested positive for the mecA gene, they were re-tested for confirmation. (Eko, K., Forshey, B., Carrel, M., Schweizer, M., Perencevich, E., & Smith, T. (2015).

    Staphylococcus is a genus of the Gram-positive bacteria which appears as grape-like clusters structure when observed under the microscope. Staphylococcus genus can be grouped into not less than 40 species, where nine of them consist of 2 subspecies and one gas three subspecies. Staphylococcus was first found in the year if 1880 by surgeon A.Ogston during a surgical abscess in a knee joint. 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).…

    According to the National Center for disease control and prevention, Methicillin-resistant Staphylococcus Aureus is a type of staph infection that is resistant to the usual antibiotics that are effective in treating other types of staph ("CDC - Definition of MRSA | MRSA Infections", 2010). Sometimes antibiotic resistant infections are called super bugs. This essay attempts to discover how it happens, how it can be prevented and possible treatments available.…

    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…

    Like I said before It can be spread through many different people, certain situations and even on your own home. Another big contribute to this is farming and the overuse of antibiotics on animals. 80 percent of the antibiotic are given to animals in the U.S alone but only sometimes are antibiotics used to save an animal (Landhus). Antibiotics are used to speed up animals growth rate and Kellogg Schwab an environmental microbiologist at John Hopkins University said that this is “a direct threat to human health” and stated that its possible that the bacteria could be spread to humans through air from the animals (JH). Although there have been a few strains of MRSA that jump from humans to livestock a study showed that 38% of farmers had a presence of MRSA in them and was strongly related to having contact with animals (persistence of livestock associated MRSA). I think this should be very concerning for Americans because we consume so much livestock everyday and we are probably getting sick from this and don't even know it. Although there are many studies I feel that nothing will change because not that many people are aware or don't know if they got sick from that or something…
