Methicillin-resistant Staphylococcus Aureus (MRSA)
is a type of staph bacteria that is resistant to certain antibiotics called beta-lactams.
These antibiotics include methicillin and other more common antibiotics such as oxacillin, penicillin, and amoxicillin.
In the community, most MRSA infections are skin infections. More severe or potentially life-threatening MRSA infections occur most frequently among patients in health care settings.
