  • There are two major ways people become infected with MRSA. The first is physical contact with someone who is either infected or is a carrier (people who are not infected but are colonized with the bacteria on their body) of MRSA. The second way is for people to physically contact MRSA on any objects such as door handles, floors, sinks, or towels that have been touched by a MRSA-infected person or carrier.

  • The aspect of Staphylococcus aureus and its genome that is most concerning revolves around the plasmids that are incorporated/associated with this bacterium’s genome.
  • Staphylococcus aureus was able to acquire antibiotic resistance through conjugation (horizontal gene transfer) of a plasmid containing a transposon
  • often code some type of antibiotic resistance.
  • Beta-lactam antibiotics target penicillin-binding proteins.
  • prevents proper peptidoglycan and cell wall formation so that cells will eventually burst as the bacteria attempt to grow larger (3).
  • econd, some bacteria can produce a modified penicillin-binding protein that no longer actually binds the antibiotic which again prevents the desired effects of the antibiotic (3).
  • The spherical bacteria is gram-positive (contains a peptidoglycan layer in its cell wall) and forms colonies that grow in two planes
  • High replication rates coupled with the great ability of to perform horizontal gene transfer (especially through conjugation) allow bacteria to develop antibiotic resistance and to spread it quickly
  • Less than 20 years after the first strains of Staphylococcus aureus were found to be resistant to penicillin, 80% of all strains had acquired penicillin resistance.
  • The decision to fight MRSA in hospitals revolves around three basic questions. First, is MRSA that much worse than MSSA? Second, how effective can we be in reducing the spread of MRSA? Lastly, is fighting MRSA cost effective?
  • Type I was isolated in 1961 in the UK, Type II in 1982 in Japan, Type III in 1985 in New Zealand and finally Type V at the start of the 21st century in Australia
  • In a paper by Deurenberg et al. two theories establishing the relationship between the first MRSA strains and present day MRSA strains are proposed. The first is called the single-clone theory which states that all MRSA clones or present day strains have a common ancestor.
  • The second theory is called the multi-clone theory. This second theory suggests that SCCmec was introduced several times into different Staphylococcus aureus. According to the paper by Deurenberg et al. the multi-clone theory has received greater support recently and it is from this paper that Figure 3 was taken.
  • he new antibiotic treatment policies did not prove to be an effective way of fighting the spread of MRSA infections in hospitals. The introduction of alcohol hand gel for improved hand hygiene did however prove to be very effective in reducing the spread of MRSA.
  • here was a 30% decrease in the spread of MRSA in the hospital. In the intervention hospital the introduction of alcohol hand gel reduced the spread of MRSA by 21%
  • The decrease experienced in the intervention hospital was likely smaller than that compared to the control hospital because the prevention measures of environmental swabbing for MRSA as well as chlorine disinfection of environments contributed to a 32% decrease in the spread of MRSA and these measures were not taken in the control hospita
  • It is even likely that these synergistic treatments can be used on other bacterial infections that are resistant to a variety of antibiotics.
  • After concluding that fighting the spread of and treating MRSA properly is crucial, can we be effective in preventing the spread of MRSA in hospitals?
  • The continued development of resistance to more and more drugs makes the treatment of Staphylococcus aureus infections and especially MRSA infections is becoming increasingly difficult.
  • have provided great insight as to what direction the fight against MRSA will be heading in
  • Staphylococcus aureus is a bacterium that naturally inhabits the skin and nose of humans. If the bacterium is able to enter the body (often through wounds or sores) it can cause a number of infections including those of the bloodstream which can become fatal.
  • quickly developed resistance to this antibiotic
  • hand hygiene in hospitals has been an effective way of decreasing the spread of MRSA in hospitals
  • Methicillin was first used to treat Staphylococcus aureus in 1959
  • Staphylococcus aureus is a spherical microbe and a member of the bacteria domain. This bacterium can be found naturally on the skin and in the mucus membranes of humans most importantly. In fact, Staphylococcus aureus can be found in the nostrils of up to 30% of people (1). The bacteria is spread most commonly through human contact be it hand-to-hand, from a wound secretion or mucus.
  • The majority of MRSA infections were wound infections (56.9%) with pneumonia cases being the second most common (21.0%). Potentially the most dangerous infection type, bloodstream infections accounted for 15.1% of the cases and urinary track infection accounted for 6.9%
  • Despite knowing that hospitals should prevent the spread of MRSA infections due to the risk of even further drug resistance over MSSA strains, and that hospitals can be effective in preventing the spread of MRSA infections, is it cost-effective for hospitals to implement the screening and isolation processes needed to fight the spread of MRSA (even though Staphylococcus aureus infections will undoubtedly occur in hospitals)? In other words, is the cost of hosting patients for longer periods of time, the costs associated with isolating patients

MRSA Infection: Get Facts on Symptoms and Treatment - 0 views

  • MRSA Infection (Methicillin-Resistant Staphylococcus aureus) Infection
  • MRSA is the abbreviation for methicillin-resistant Staphylococcus aureus. Staphylococcus is a group of bacteria, familiarly known as Staph (pronounced "staff"), that can cause a multitude of diseases as a result of infection of various tissues of the body.
  • Because MRSA is so antibiotic resistant, it is termed a "superbug" by some investigators. This superbug is a variation of an already recognized human pathogen, S. aureus, gram-positive bacteria that occur in grape-like clusters termed cocci.
  • ...2 more annotations...
  • However, damage to the skin or other injury may allow the bacteria to overcome the natural protective mechanisms of the body and lead to infection; because of its ability to destroy skin, it is also one of the types of bacteria that has been termed a "flesh-eating bacterium."
  • Plasmids (extra-chromosomal genetic material) that code for antibiotic resistance can be transferred between these two bacterial types and other types of bacteria such as Escherichia (E. coli</i>). Also, the lay press has occasionally labeled MRSA as a virus; this is a mistake but people still report it from time to time so don't be confused if the term MRSA virus reappears, as it will be corrected in most instances.

  • MRSA stands for methicillin-resistant Staphylococcus aureus. Staphylococcus aureus is a type of bacteria with lots of different strains.
  • What makes the MRSA different from other staph bacteria is that it has built up a resistance to most of the antibiotics doctors usually use to treat staph infections. (Methicillin is a type of antibiotic, which is why the strain is called "methicillin-resistant.")
  • MRSA usually affected people with weakened immune systems, like people living in nursing homes and other long-term care facilities.
  • People at greater risk for becoming infected with this germ are those who spend a lot of time together in groups, such as in schools, college dorms, or military barracks.
  • When lots of people come together and are likely to touch the same surfaces, have skin-to-skin contact, or share equipment that has not been cleaned, an infection can spread faster than it would otherwise.
  • MRSA is contagiouscontagious during a skin infection. Sometimes, people can be "carriers" of MRSA, which means the bacteria stay on or in their body for days, weeks, or even years. They can spread it to others, even if their skin looks normal. That's hand washing is so important.
  • The good news is that MRSA infections are rare in teens. And if a healthy person does get one, a doctor can treat it.
  • easy to prevent MRSA from spreading by practicing simple cleanliness.
  • Wash your hands
  • a cut or broken skin, keep it clean and covered with a bandage.
  • Don't share razors, towels, uniforms, or other items that come into contact with bare skin.
  • Cover shared sports equipment with a barrier (clothing or a towel) to prevent skin from touching it
  • Call the doctor if: You have an area of skin that is red, painful, swollen, and/or filled with pus. You have an area of swollen, painful skin and also feel feverish or sick. Skin infections seem to be passing from one family member to another (or among students in your school) or if two or more family members have skin infections at the same time.
  • MRSA infections can need different medicines and approaches to treatment than other staph infections. For example, if a person has a skin abscess caused by MRSA, the doctor is more likely to have to drain the pus from the abscess in order to clear the infection. In addition to draining the area, doctors may prescribe antibiotics for some people with MRSA infections.
  • People with infections also can help prevent other bacteria from becoming resistant to antibiotics in the future by taking the antibiotics that have been prescribed for them in the full amount until the prescription is finished (unless a doctor tells them it's OK to stop early). Germs that are allowed to hang around after incomplete treatment of an infection are more likely to become resistant to antibiotics.
  • Many strains of staph bacteria are quite common. Most people have staph bacteria living on their skin or in their noses without it causing any problems.
  • Most of these heal on their own if a person keeps the wound clean and bandaged. Sometimes doctors prescribe antibiotics to treat more stubborn staph infections.
  • MRSA skin infections often develop around open sores, like cuts, scrapes, or bites; but they also can occur on intact skin. Red, swollen, painful bumps appear that sometimes weep fluid or pus. Some people also develop a fever.

  • MRSA infections are rare, and most infections can be treated easily.
  • MRSA stands for methicillin-resistant Staphylococcus aureus, a type of staph bacteria. Many strains of staph bacteria are quite common, and most of us have staph bacteria living harmlessly on our skin or in our noses.
  • When bacteria are resistant to antibiotics, they are harder to kill. They become resistant by changing in some way that affects the ability of the antibiotic to do its job.

  • taking antibiotics for things that they can't cure, like viruses not taking antibiotics properly when they are needed (like not taking all the medicine prescribed or taking another person's medicine that wasn't prescribed for you)
  • MRSA is not a new infection. The first case was reported in 1968. In the past, MRSA usually affected people with weakened immune systems, such as those living in long-term care facilities like nursing homes.
  • Groups of kids who spend a lot of time together in close quarters (such as in schools, camps, or college dorms) are most at risk. MRSA can spread through direct contact with infected skin or by sharing personal items (towels, razors, etc.) that have touched infected skin.
  • Sometimes, people can be "carriers" of MRSA, which means that the bacteria stay on or in their bodies for days, weeks, or even years.

  • It is important to understand that, while MRSA begins as a skin infection, it spreads easily to other parts of the body; in fact, it can affect just about any of the vital organs.
  • MRSA can be transmitted from the skin or clothing of an infected person, or by contact with chairs, benches, other furniture and utensils that have been used by one.
  • Facts
  • Methicillin-resistant Staphylococcus aureus is a highly resistant bacteria that is surprisingly common
  • There are two main types of MRSA: CA-MRSA which stands for ‘community or commonly acquired’ and HA-MRSA, meaning ‘hospital acquired’; the first type is not associated with a health care issue, the second is acquired in a hospital or other health care institute.
  • When the bacteria attacks the organs – and it can be found in any organ in the body – it can cause a number of potentially fatal problems, including: endocarditis
  • resistant to multiple antibiotics.
  • best prevention method is attention to personal hygiene.
  • Fever and chills Headaches Shortness of breath Low blood pressure Pains in the joints
  • Methicillin, a common antibiotic used in many instances, was proven to be useless against the MRSA bacteria, and it has since evolved to become resistant to many more of the most advances antibiotics we know of. It is important to explain that MRSA is not a virus; it is a bacterial infection. It is a common bacteria that occurs across the world, and it is very difficult to estimate the numbers of people who have died from complications brought about by MRSA.
