Distinguishing methicillin-susceptible S. aureus from methicillin-resistant S. aureus (MRSA) is fundamental for therapeutic choices. A crucial emerging concept in the treatment of acute bacterial skin and skin structure infections is the availability of various approved agents with anti-MRSA activity, which allow a personalized approach based on the characteristics of any given patient while at the same time remaining in line with high certainty efficacy evidence from large randomized controlled trials. Regarding the treatment of S. aureus bloodstream infections (BSI), interesting aspects that may become relevant in the near future are the presence of both old and novel agents in phase-2 or phase-3 of clinical development for this indication, and the pressing need for high certainty evidence to guide the possible use of combination therapy in specific categories or phenotypes of patients with complicated MRSA BSI.Keywords: Staphylococcus aureus, MSSA, MRSA, ABSSSI, BSI, bacteremia
