A study on infective endocarditis (IE) caused by methicillin-susceptible Staphylococcus aureus (MSSA) found that clinical features and medical-surgical management, such as cardiac surgery and source control, are more significant for improved outcomes than the inoculum effect or genotypic characteristics of the bacteria. The inoculum effect of cefazolin and oxacillin was observed in some strains, but it was not associated with Day-90 mortality.
Clinical features and medical-surgical management are key to improved outcomes in MSSA infective endocarditis.
Cardiac surgery and source control are independently associated with improved outcomes.
In vitro inoculum effect to primary antibiotherapy was not associated with Day-90 mortality.
Cefazolin inoculum effect observed in 18/88 strains.
Oxacillin inoculum effect observed in 13/88 strains.
