Methicillin-Resistant Staphylococcus Aureus or MRSA (usually pronounced "mur-sah") is a type of bacteria. Staphylococcus aureus is a common bacterium on skin, and it is not usually a problem. However, when the Staphylococcus aureus bacteria are not susceptible to the antibiotic methicillin (ie, methicillin does not kill the bacteria or stop its growth), it is considered to be MRSA. Bacteria resistant to methicillin are often resistant to other antibiotics as well.

If MRSA is present, it is commonly carried on the skin or in the nasal passages of healthy people and/or pets. If an infection is present, it can be found almost anywhere—especially where there's a skin wound or sore
