Staphylococcus aureus ("staph") is a common type of bacteria (germ) that is often found on the skin and in the nose of healthy people. It can also grow in wounds or other sites in the body, sometimes causing an infection. For example, staph is one of the most common causes of skin infections. Penicillin is a drug that was once commonly used to treat staph infections.

MRSA is usually transmitted by direct skin-to-skin contact or contact with shared items or surfaces that have come into contact with someone else's infection (e.g., towels, used bandages). See similar questions...

MRSA can be carried on the skin or in the nose without causing any disease, which is called colonization . Approximately 25-30% of the population is colonized in the nose with staph bacteria at any given time; however, the proportion colonized with MRSA is not known. The exact number of new cases of MRSA infections in Oregon is unknown but the number of cases of MRSA in general is increasing. See similar questions...

Symptoms of MRSA infection are, for the most part, not different from any other staph infection. MRSA may manifest as red, swollen, tender skin surrounding a cut or in the form of a large pimple (boil) and may include drainage of thick white pus. In more serious cases, the infection may cause difficulty breathing, fever and excessive tiredness. If a child develops these symptoms, a parent should contact a doctor. See similar questions...

Colonization of the skin or nose usually is not a reason for antibiotic treatment except in special circumstances. Small, localized skin pimples or boils may improve without use of antibiotics. When antibiotics are required, there are usually only a few from which to choose. MRSA bacteria are resistant to penicillin and all penicillin-like drugs. Most hospital-acquired MRSA are also resistant to numerous other antibiotics. See similar questions...
