Methicillin-resistant staphylococcus aureus, or MRSA, is a strain of staph infection that is resistant to certain antibiotics. Methicillin is just one of the many antibiotics this particular strain of staph bacteria is immune to. There are two types of MRSA that can infect a person, healthcare-associated and community associated. Although the resiliency of MRSA has made it challenging to defeat, the infection is treatable and avoidable.
The two types of MRSA appear in the body in different circumstances.
Health-associated MRSA infects a person in a hospital or healthcare facility setting. This includes nursing homes, dialysis centers, emergency rooms, and even doctor offices. The chances of acquiring health-associated MRSA are not high, but has slowly increased over the past several years. People become more at risk to contract MRSA when

However, the longer the disease has settled in the body the more complicated it is to treat. Someone who has just begun to develop MRSA may be able to eliminate the infection with certain antibiotics. Though MRSA is highly resistant to typical antibiotics such as penicillin and amoxicillin, other medications such as trimethoprim, sulfamethoxazole, and clindamycin may be able to rid the body of this infectious disease. Applying topical antibiotic ointment to the infected areas also aids the body of ridding MRSA. For further progressed methicillin-resistant staphylococcus aureus, more invasive options such as surgical drainage will become a possibility. It is best to avoid the level of infection where surgery is required due to the risk factors involved. With every surgery, even minor ones such as surgical drainage, there is a probability of further complications. This includes further infection, allergic reactions, and mistakes made by physicians. The sooner MRSA is discovered and treated by a medical professional the easier it and less risky it is to
Hospital-acquired infections (HAI) are preventable and pose a threat to hospitals and patients; increasing the cost, nominally and physically, for both. Pneumonia makes up approximately 15% of all HAI and is the leading cause of nosocomial deaths. Pneumonia is most frequently caused by bacterial microorganisms reaching the lungs by way of aspiration, inhalation or the hematogenous spread of a primary infection. There are two categories of Hospital-Acquired Pneumonia (HAP); Health-Care Associated Pneumonia (HCAP) and Ventilator-associated pneumonia (VAP).
In one of the studies healthcare workers were provided a questionnaire only 27.3% responded that no other healthcare worker had ever talked to them about MRSA (Raupach-Rosin, et. al, 2016). This study proves that healthcare workers need to be more educated on the topic of MRSA, how it spreads to the patients, and how the intervention of infection control and patient education will assist in reducing the amount of MRSA cases acquired. In one study, patients underwent a MRSA screening for nasal colonization. Out of the 29,371 patients, 3,262 had MRSA colonization. (Marzec & Bessesen, 2016). The study conducted allowed healthcare providers to see the effects of how easily MRSA is spread and how many patients could easily contract
Staphylococcus aureus is a bacteria that is abundant in many places. It can even be found in some of our bodies. These bacteria are harmless as long as none of them are Methicillin resistant Staphylococcus aureus (MRSA). Methicillin is the name of a family of antibiotics that includes penicillin. This MRSA is the deadly superbug that has developed resistant to antibiotics. Statistics show that MRSA contributes to more US deaths than does HIV. It has become a huge threat to every country as the outbreaks can be a surprising one. This threat is caused by the evolution of the bacteria. These superbugs have evolved a resistance of antibiotics which makes them extremely difficult to treat. One article states, “In the early 1940s, when penicillin was first used to treat bacterial infections, penicillin-resistant strains of S. aureus were unknown — but by the 1950s, they were common in hospitals. Methicillin was introduced in 1961 to treat these resistant strains, and within one year, doctors had encountered methicillin-resistant S. aureus. Today, we have strains of MRSA that simultaneously resist a laundry list of different antibiotics, including vancomycin — often considered our last line of antibacterial defense.” [1]
...ood to above 60 degrees C and storing food below 7.2 degees C are two effective ways of controling S. aureus growth in food. The most important recent epidemiological information concerning this organism involves the increasing resistance to antibiotics. Methicillin-resistant S. aureus (MRSA) is the most common of these antibiotic resistant organisms. The effects of MSRA are the same as any other S. aureus infection, however, MSRA infections are a difficult to treat because there are few effective antibiotics available. MSRA infections are generally not life threatening, however in some extreme cases death can occur.
One factor prevalent in our nation’s hospitals which, although under-represented by the media, is significantly detrimental to the advancement of the United States healthcare system is Hospital/Healthcare Associated Infections, or HAIs. These infections were first identified as a serious threat to patient safety during the 1930s. In the 1940s, The British Medical Council appointed infection officers in various hospitals to attempt to regulate and control causes of infection, although such officers only became common in the 1950s during a severe outbreak of Staphyloccosus. After a brief investigation had been conducted, it was found that nearly 100% of patients and staff in various British hospitals had contracted elements of the virus through lack of hygienic precaution during open wound surgeries. Fortunately, the ready availability of penicillin prevented a severe outbreak, but the continued overuse of the drug resulted in drug resistant bacteria and virus and the discovery of the Staphyloccosus Aureus - a virulent skin pathogen immune to initial penicillin serums and recognized as the first antibiotic resistant bacterium - in the late 1960s. By the early 1970s, the drive to control hospital infections was well established in the United States, however, the movement was unorganized and there was no success in eliminating infections associated with medical practices at the time. It was not until 1976 that the control of infectious diseases in hospitals was transformed from a movement to a mandate when The Joint Commission on Accreditation of Hospitals demanded that accredited hospitals have infection control programs. Currently the majority of research of HAIs is conducted by the CDC through The Prevention Epicenter Program, w...
“Antibiotics" is the name given to the group of chemicals, particularly in medicine, that stop or inhibit the growth of, microorganisms such as fungi, bacteria, and parasites, or that kill the microorganism. They are, however, completely ineffective against viruses. There are two kinds of antibiotics, namely; bactericides, which interfere with the cell wall or contents of the bacteria, thereby killing it, and bacteriostatics, which prevent the bacteria from reproducing. They are used to treat bacterial infections in humans and animals. Bacteria are microorganisms consisting of single cells, and reproduce by mitosis. They usually live in colonies. Some bacteria and other microorganisms produce antibiotics to kill off other species, making more resources available for the organism making the chemicals. Ironically, it was this that led to the discovery of antibiotics in 1928, when Alexander Fleming noticed that the fungus Penicillium notatum, which had contaminated a sample of pathogenic bacteria, had killed the bacterial colonies in a petri dish.
Patient education is of paramount importance if MRSA is to be reduced to its lowest minimum. According to Noble 2009, patient’s education stands a critical component of managing MRSA therefore; nurses are expected to be prompt in educating patients on specific measures in limiting and reducing the spread of MRSA by person to person contact. (Noble, 2009) The specific measures includes definition of MRSA, mode of transmission, the damage it can do to the body, specific treatments available and the process of treatment. This is to help the patient take part in the care. Noble 2009 explains that during care giving nurses and all other healthcare provider involve in giving care to a patient should communicate to patient all the precaution that will prevent the transmission of MRSA, and also giving the scientific rationale for the use of any precaution that is been used in the cause of care giving. (Noble, 2009.)
Resistant strains are no joke, for years my mother has been dealing with MRSA (methicillin-resistant staphylococcus aureus). My mother has had MRSA so bad that at one time she was covered in MRSA sores much like when a person breaks out in hives. Watching her suffer the way she has worries me as I am also a healthcare worker and know what these resistant strains are capable of. I know these strains exist because of a lack of proper patient education. Proper patient education is key to the use of antibiotics and prevention of resistance-bacteria strains.
Hospital acquired infections are one of the most common complications of care in the hospital setting. Hospital acquired infections are infections that patients acquired during the stay in the hospital. These infections can cause an increase number of days the patients stay in the hospital. Hospital acquired infections makes the patients worse or even causes death. “In the USA alone, hospital acquired infections cause about 1.7 million infections and 99,000 deaths per year”(secondary).
The controversy regarding the sub-therapeutic use of antibiotics in animal feeds is that “super-bugs” are able to evolve. This is a threat to both the health of the animals and humans. What a “super-bug” refers to is a strain of bacteria that has evolved to be resistant to bacteria and lethal to the host organism. These super-bugs account for the death of roughly 48,000 Americans each year (Adams, 2013). These superbugs proliferate in the digestive tracts of hosts. Each dose of antibiotics in the animals’ diets at sub-therapeutic levels increases the likelihood of antibiotic resistance bacteria to evolve. The antibiotics kill the antibiotic sensitive bacteria, but bacteria that are resistant proliferate in the gut of the animals. When these antibiotic resistant bacteria are left to grow in the gut, they can cause infection to the animal or people that consume the animal as food (Falco, 2013, Amachawadl et. al. 2013). Antibiotic-resistance can also be conferred through horizontal gene transfer and other methods, making the mere existence of such bacteria a threat that should not be taken lightly.
Biological evolution is defined as any genetic change in a population that is inherited over several, successive generations. (R.Bailey, 2014) The changes accumulate and over time a new species is created. One of the basic mechanisms of evolution is Natural Selection. Natural Selection is random genetic variation occurring within an organisms DNA and the beneficial mutations being preserved because they aid survival. (C.Darwin, 1859) Two notable scientists associated with the theory of evolution include Charles Darwin and Jean-Baptiste Lamarck.
Bacterial cells, like plant cells, are surrounded by a cell wall. However, bacterial cell walls are made up of polysaccharide chains linked to amino acids, while plant cell walls are made up of cellulose, which contains no amino acids. Many bacteria secrete a slimy capsule around the outside of the cell wall. The capsule provides additional protection for the cell. Many of the bacteria that cause diseases in animals are surrounded by a capsule. The capsule prevents the white blood cells and antibodies from destroying the invading bacterium. Inside the capsule and the cell wall is the cell membrane. In aerobic bacteria, the reactions of cellular respiration take place on fingerlike infoldings of the cell membrane. Ribosomes are scattered throughout the cytoplasm, and the DNA is generally found in the center of the cell. Many bacilli and spirilla have flagella, which are used for locomotion in water. A few types of bacteria that lack flagella move by gliding on a surface. However, the mechanism of this gliding motion is unknown. Most bacteria are aerobic, they require free oxygen to carry on cellular respiration. Some bacteria, called facultatibe anaerobes can live in either the presence or absence of free oxygen. They obtain energy either by aerobic respiration when oxygen is present or by fermentation when oxygen is absent. Still other bacteria cannot live in the presence of oxygen. These are called obligate anaerobes. Such bacteria obtain energy only fermentation. Through fermentation, different groups of bacteria produce a wide variety of organic compounds. Besides ethyl alcohol and lactic acid, bacterial fermentation can produce acetic acid, acetone, butyl alcohol, glycol, butyric acid, propionic acid, and methane, the main component of natural gas. Most bacteria are heterotrophic bacteria are either saprophytes or parasites. Saprophytes feed on the remains of dead plants and animals, and ordinarily do not cause disease. They release digestive enzymes onto the organic matter. The enzymes breakdown the large food molecules into smaller molecules, which are absorbed by the bacterial cells. Parasites live on or in living organisms, and may cause disease. A few types of bacteria are Autotrophic, they can synthesize the organic nutrients they require from inorganic substances. Autotrophic bacteria are either photosynthetic or Chemosynthetic. The photosynthetic bacteria contain chlorophyll that are different from the plant chlorophyll. In bacterial photosynthesis, hydrogen is obtained by the splitting of compounds other than water.
Infection control is very important in the health care profession. Health care professionals, who do not practice proper infection control, allow themselves to become susceptible to a number of infections. Among the most dreaded of these infections are: hepatitis B (HBV), hepatitis C (HCV), and human immunodeficiency virus (HIV). Another infection which has more recently increased in prevalence is methicillin-resistant Staphylococcus aureus (MRSA). These infections are all treated differently. Each infection has its own symptoms, classifications, and incubation periods. These infections are transmitted in very similar fashions, but they do not all target the same population.
The most effective way to combat pathogenic bacteria which invade the body is the use of antibiotics. Overexposure to antibiotics can easily lead to resistant strains of bacteria. Resistance is dangerous because bacteria can easily spread from person to person. Simple methods for preventing excessive bacterial spread are often overlooked. Not all preventative measures are even adequate. Doctors and patients often use antibiotics unnecessarily or incorrectly, leading to greater resistance. Antibiotics are used heavily in livestock and this excessive antibiotic use can create resistant bacteria and transfer them to humans. In order to reduce resistant bacteria,
MRSA is a major source of healthcare associated diseases, increased hospital mortality, and leading surgical site infection (Jennings, Bennett, Fisher, & Cook, 2014, p. 83). With the implementation of active surveillance screening and contact isolations program, an overall decrease in hospital associated MRSA infections has been observed (Jennings, Bennett, Fisher, & Cook, 2014, p. 83). The author of this paper will identify a theory that can be used to support the proposed intervention i.e., reduce the transmission of MRSA by active screening in patients at high-risk for MRSA on admission. This paper will then describe the selected theory, and rational for the selection, and how this theory will support the proposed solution and how to incorporate this theory in this project.
