Enhanced Killing of Methicillin-Resistant Staphylococcus aureus with Ceftaroline or Vancomycin in Combination with Carbapenems.

Background: Methicillin-resistant Staphylococcus aureus (MRSA) bacteremia is associated with high rates of treatment failure, even when antibiotics showing in vitro susceptibility are used. Early optimization of therapy is crucial to reduce morbidity and mortality. Building on our previous research on carbapenem therapy for methicillin-susceptible S.
