MRSA (methicillin resistant staphylococcus aureus) is a type of staphylococcus bacteria (staph) that is resistant to beta-lactam antibiotics. MRSA is contagious and can cause life-threatening infection. MRSA isnât found in the natural environment (soil or water).
Staph bacteria can cause a wide range of infections, from relatively minor skin infections such as boils, to more serious infections of the blood, lungs and heart. There are many types of Staphylococci, but most infections are caused by a group called Staphylococcus aureus.This group of bacteria includes meticillin-resistant Staphylococcus aureus (MRSA) , which is resistant to certain antibiotics that are commonly used for staph infections, such as flucloxacillin.nvasive infections. In a small number of people, a staph skin infection can lead to a more serious, invasive infection deeper within the body. Examples include: 1  septic arthritis â a joint infection that causes pain, swelling, redness and tenderness in affected joints.
