Methicillin-resistant Staphylococcus aureus (MRSA) infection Written by Dr Alan Johnson, clinical scientist
What is MRSA?
Staphylococcus aureus is a species of bacterium commonly found on the skin and/or in the noses of healthy people. Although it is usually harmless at these sites, it may occasionally get into the body (eg through breaks in the skin such as abrasions, cuts, wounds, surgical incisions or indwelling catheters) and cause infections. These infections may be mild (eg pimples or boils) or serious (eg infection of the bloodstream, bones or joints).
MRSA stands for methicillin-resistant Staphylococcus aureus, which is a type of Staphylococcus aureus that is resistant to the antibacterial activity of methicillin and other related antibiotics of the penicillin class.
