Short summary
In this study, we tested whether very high doses and prolonged exposure of gentamicin, alone or with rifampin, can eliminate mature Staphylococcus aureus biofilm – one of the main causes of implant-associated infections. None of the regimes tested eradicated all bacteria. Adding rifampin gave no benefit. This suggests that aminoglycosides are not optimal for local antibiotic therapy.
