All children and 20-40 % of healthy human adults carry in it their noses and skin without causing any harmful effects. But in certain circumstances such as the rupture of skin this organism causes boils, wounds or serious infections such as pneumonia, and bacteraemia. Provided the immune systems are well it is unlikely that individuals will get a staphylococcal infection. But within a hospital setting people are ill often with their immune system working at limited efficiency or they may have open wounds making access into the body easy therefore rendering the susceptibility to this organism greater. Sometimes the bacterium can get inside the body by synthetic devices such as urinary catheters or surgical implants. Antibiotics were first discovered in 1928 and since then the 6000 or so antibiotics, which were either discovered or created, have successfully eliminated an enormous range of da
