Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterium that causes infections in different parts of the body. It's tougher to treat than most strains of staphylococcus aureus -- or staph -- because it's resistant to some commonly used antibiotics.
MRSA is most common as a skin infection, as staph are common bacteria that live on the skin. They cause infection whenever they enter the skin through a cut or sore. A person can also become infected with MRSA when the bacteria move inside of the body through a catheter, breathing tube, or other entry point.
