Methicillin-resistant Staphylococcus aureus (MRSA) is a specific strain of the Staphylococcus aureus bacterium that has developed antibiotic resistance to all penicillins, including methicillin and other narrow-spectrum β-lactamase-resistant penicillin antibiotics.[1] MRSA was first discovered in the UK in 1961 and is now widespread, particularly in the hospital setting where it is commonly termed a superbug.
MRSA may also be known as oxacillin-resistant Staphylococcus aureus (ORSA) and multiple-resistant Staphylococcus aureus, while non-methicillin resistant strains of S. aureus are sometimes called methicillin-susceptible Staphylococcus aureus (MSSA) if an explicit distinction must be made.
Staphylococcus bacteria is extremely common in the environment, and is usually not a problem to healthy individuals. Historically, staph infections begin only after the individual has suffered a skin break or open wound. Recently, due to institutional overuse of antibiotics, strains of staphylococcus aureus have developed drug resistance. If an individual has a weak immune response to the bacteria, a MRSA infection can result even with no apparent open wound. The symptoms can range from skin boils to necrotizing fasciitis, popularly known as flesh-eating disease. MRSA infections are typically combatted with vancomycin, however, vancomycin-resistant staphyloccocus has recently appeared.
Interestingly, MRSA cases chiefly emanate from institutions such as hospitals and gymnasiums. Many professional athletes have developed MRSA infections from exposure in stadium locker rooms. On June 22, 2006, the U.S. Center for Disease Control issued an alert regarding an outbreak in tattoo parlors [1], after 54 customers developed MRSA from unlicensed tattoo artists.
Up to 53 million people are thought to carry MRSA. Scientists estimate that around 2 billion people, some 25-30 percent of the world's population, have a form of the Staphylococcus aureus bacteria. [3] [4]
Because cystic fibrosis patients are often treated with multiple antibiotics in hospital settings, they are often colonised with MRSA, potentially increasing the rate of life-threatening MRSA pneumonia in this group. The risk of cross-colonisation has led to increased use of isolation protocols among these patients. In a hospital setting, patients who have received fluoroquinolones are more likely to become colonised with MRSA,[4] this is probably because many circulating strains of MRSA are fluoroquinolone-resistant, which means that MRSA is able to colonise patients whose normal skin flora have been cleared of non-resistant Staph. aureus by fluoroquinolones.
In the US there are increasing reports of outbreaks of MRSA colonisation and infection through skin contact in locker rooms and gymnasiums, even among healthy populations. MRSA also is becoming a problem in paediatrics.

meticiline resistant staph aureus (MRSA) is a kind of bacterium which can't be treated with routine abtibiotic theraphy and its hard to avoid.. especially in intensive care units and burn centers.. but, normal healthy people generally not affected as a bad way. they just carry this one to another. when your husband gets wounded or sick, it will be a problem for him..

He should investigate colloidal silver 500ppm, it kills over 650 types of viruses, bacteria, yeasts, and fungi. They cannot build a resistance to it because of the way it kills them. I get mine at herbalhealer.com and you can read testimonials of other people there also. I have used it for years without problems both topically and orally. Check it out and good luck, I work in a hospital also so I know how it is.
