What Causes Mercer Disease?

Mercer disease (MRSA) is an infection. It is caused by Staphylococcus aureus. The MRSA is a acronym for METHICILLIN RESISTANT STAPHYLOCOCCUS AUREUS. Otherwise referred to as ‘Staph’. This bacteria is usually found in a person’s nose or on the skin and is harmless unless it enters the body through a wound or cut.
