S. Aureus (MRSA)

Improved Essays
Everyone carries harmless bacteria on their skin. These bacteria reside as normal flora on our skin and play a significant role in preventing harmful bacteria from invading our body. One form of bacteria that you may have already heard of is found in 1/3 of the human population and is causing quite a stir in the medical community because of it's growing resistance to many forms of antibiotics (CDC, 2016). This bacteria, nick-named a super bug, is known as Methicillin-resistant Staphylococcus aureus or MRSA, for short. First discovered in 1961, MRSA has grown significantly resistant to many forms of antibiotics at an alarming rate, and pharmaceutical companies, researching for new forms of medicine, are having a tough time keeping up. MRSA is …show more content…
aureus is found in 1/3 of the human population and commonly resides in the nose, pharynx and skin of healthy, immunocompetent individuals. It can be transmitted through the air by coughing and sneezing and can also be transmitted through direct contact with objects infected with the bacteria. S. aureus is opportunistic, entering the body through wounds, abscesses and broken skin and can be life-threatening in those who are immunocompromised. This bacteria manifests itself in a variety of ways and can appear as minor skin infections, such as pimples, carbuncles and boils, or life-threatening conditions such as meningitis, endocarditis and septicemia (CDC, 2016). A dose of antibiotics is typically effective in treating Staphylococcus infections but due to higher antibiotic resistance it has become a pertinent issue in the medical community. Since the development of penicillin, countless lives have been saved over the years but over-prescribing and misuse of the medication has played a large role in the antibiotic resistance crisis. As a result, resistant strains of S. aureus have grown and spread into the community, some even showing resistance to multiple antibiotics (Ventola, 2015). Prior to the discovery of penicillin, death due to bacterial infections was quite common. When penicillin was first introduced to the public in the 1940's, it was found to be very effective at curing bacterial illnesses and also played an immense role in controlling infections during WWII. 10 years after it's introduction to the public, the first case of penicillin resistant S. aureus was

    For instance penicillin is known to be effective against gram positive bacteria including Staphylococcus aureus of which during its activity forms surface protein that binds and leads to the osmotic lysis (Willey et al, 2011 page832). However, there are some emergences of bacteria resistance to penicillin causing pathogenic Staphylococcus aureus infections know as Methicillin – resistant Staphylococcus aureus (MRSA) (Chaitow, 1998) commonly found in hospitals. The results showed that Ciprofloxacin (C) was effective against S. aureus solid proof backing the literature that the drug has capabilities against gram-negative species better than Gram –positive (Heritage et al, 1999).…

    It is unfortunately quite a common infection in the United States and worldwide. Individuals who are hospitalized have the greatest risk of becoming infected. Improper hand washing, the lack of sterilization and disinfection, and not using the right personal protective equipment, as well as not using it effectively are the biggest reasons why nosocomial infections such as MRSA are spread in health care settings. I want to be a Dental Hygienist and in order to prevent the spread of MRSA in medical facilities we can start by always washing our hands in between everything we do. Instead of taking off our gloves and slipping into another pair we should be washing our hands in between every pair we switch to because the insides of gloves are wonderful, warm and moist environment for bacteria to flourish and grow in.…

    S. aureus is clinically recognised as an important pathogen in terms of human infection. Despite its common presence in the natural microbiota of the human body, S. aureus is one of the leading causes of nosocomial infections. Infection with this pathogen can lead to a range of disorders from relatively mild skin infections to life threatening illness such as osteomyelitis. The ability of S. aureus to control expression of a virulent phenotype according to environmental conditions is regulated by the agr QS pathway [1]. Many of the factors involved in virulence, such as exotoxin production, as well as products associated with the formation of biofilm have been shown to be controlled by the agr system [2, pdf 575], see table 1.…

    Antibiotic resistant bacteria are bacteria that are resistant to the antibiotics that at one time were able to kill them. It is a growing issue in today’s society especially since it is unknown how these microbes are able to mutate around a treatment that was once lethal to them. The consensus in the healthcare community is that these microbes will be an increasing threat until a solution is found. There is still discussion and controversy over the best method of identification and infection control that should be put into practice to prevent the spread of multidrug resistant bacteria. However, the most prevalent controversy surrounding this topic seems to be over how the taxpayer’s money is best spent related to new treatment of these microbes,…

    Wound infection is one of the most common causes of death in modern society, especially in people less than 44 years(Shu Fan et al., 2013). Bacterial microorganisms can gain access from environment or from surrounding skin surface into underlying tissue when patient compromised and physical characteristics are optimal for colonization and growth(Irena Pastar et al., 2013).Presence of microorganism that proliferate without immune response is known as colonization.(Abdul R. Siddiqui and Jack M. Bernstein, 2010). Delay in wound healing characteristic by excessive amount of exudates that affect healthy skin tissue around the wound (Boateng and Catanzano, 2015).

    After the discovery of antibiotics in the early to middle 1900s, many people, including scientists, marveled at the thought of eradicating diseases that tortured human life for centuries. Recently, however, the widespread and inappropriate use of antibiotics has led to antibiotic resistance all over the world, becoming a very serious problem in the treating of diseases. Antibiotic resistance occurs over time when bacteria become resistant to antibiotics because the bacteria strains adapt quickly and protect themselves from the antibiotic. The antibiotic loses its ability to terminate the growth of bacteria, leaving people who suffer from infections with fewer options for recovery. If large numbers of bacteria are resistant to antibiotics,…
