MRSA stands for Methicillin-resistant Staphylococcus aureus which is a different strain of staphylococcus aureus. It is a gram-positive bacteria and is able to cause infections in many human body parts like on skin it can cause sores, boils, wound infection and if it gets into the bloodstream it can infect the urinary tract, lungs, etc.
