Staphylococcus aureus (MSSA)
Staphylococcus aureus is a bacterium found on the skin and a proportion (up to 30%) of the healthy population carry Staph. aureus in their nose or in other moist parts of the body. However, it is a more aggressive bacterium than the coagulase negative staphylococci.
Commonly Staphylococcus aureus causes infections such as boils and infected skin wounds. It can cause pneumonia, urinary tract infections and bacteraemia both in the community and in hospital practice.
Some types of Staph. aureus have become resistant to various antibiotics. These are known as methicillin resistant Staph. aureus or MRSA. Those types that are not resistant to certain antibiotics are known as methicillin sensitive Staph. aureus or MSSA.
