Methicillin-resistant Staphylococcus aureus (MRSA)
Staphylococcus aureus, or more simply "staph," are bacteria that often live in the nose or on the skin of healthy people. When these bacteria penetrate the skin or invade other parts of the body, a staph infection may result. Staph bacteria that are resistant to the action of methicillin and related antibiotics are referred to as "methicillin-resistant staph aureus" or MRSA.
MRSA bacteria are not only resistant to all penicillin-like antibiotics, but they are often resistant to many other types of antibiotics as well. Infections with MRSA can be costly and difficult to treat because of limited antibiotic options. In the past, MRSA has been a problem mainly in healthcare settings such as hospitals and nursing homes (healthcare-associated MRSA). Recently however, there have been many reports of MRSA infections—particularly skin and soft tissue infections such as boils, abscesses, and cellulitis—occurring among persons in the general community without any healthcare contact. These types of infections are labeled community-associated MRSA (CA-MRSA).
MRSA cases are not reportable in Oregon.
