The soluble copper silicate (CS) MIC of 100 strains of methicillin resistant Staphylococcus aureus (MRSA) and 100 strains of methicillin susceptible S. aureus (MSSA) was 175 mg Cu/L. Bactericidal and postantibiotic effects (PAE) (>/=1 h) were seen at 2xMIC and 4xMIC. The frequency of mutation was <10(-9), and serial passage could not extend growth beyond 1.6xMIC.
