Methicillin-Resistant Staphylococcus Aureus (MRSA) 

      What is Staphylococcus aureus? - Staphylococcus aureus, often referred to simply as "Staph," are bacteria commonly carried on the skin or in the nose of healthy people. Approximately 25% to 30% of the population is colonized (when bacteria are present, but not causing an infection) in the nose with Staph bacteria. Sometimes, Staph can also cause an infection. Staph bacteria are one of the most common causes of skin infections in the United States. Most of these skin infections are minor (such as pimples and boils) and can be treated without antibiotics. However, Staph bacteria also can cause serious infections (such as surgical wound infections, bloodstream infections, and pneumonia).

    

    What is MRSA (methicillin-resistant Staphylococcus aureus)? - Some Staph bacteria are resistant to antibiotics. MRSA is a type of Staph that is resistant to antibiotics called beta-lactams. Beta-lactam antibiotics include methicillin and other more common antibiotics such as oxacillin, penicillin and amoxicillin. While 25% to 30% of the population is colonized with Staph, approximately 1% is colonized with MRSA.
