Both methicillin-susceptible Staphylococcus aureus (MSSA) and methicillin-resistant S. aureus (MRSA) can cause potentially severe infections, such as bacteraemia, surgical site infections, complicated skin and soft tissue infections (SSTI), and ventilator-associated pneumonia. However, they are also involved in a large number of mainly minor SSTI and are often mere colonizers without leading to clinical infections. Severe MRSA infections are associated with increased length of stay, morbidity, cost (primarily driven by increased length of stay and not by the cost of antimicrobials) and mortality. In a large meta-analysis of 31 studies of S. aureus bacteraemia pooled between 1980 and 2000 [1], Cosgrove et al. [1] found a doubling of mortality with MRSA bacteraemia (OR 1.93; 95% confidence interval (CI) 1.542.42; P<0.001 vs MSSA). In another calculation, MRSA bacteraemia
