Abstract:
Biofilms formed by Candida albicans bloodstream isolates on catheters are an important clinical problem. Devising chemotherapeutic strategies to treat these in situ is an attractive option. We report here that liposomal amphotericin effectively kills C. albicans biofilms rapidly (12 h) and effectively (>90%) in a dose-dependent manner, whereas caspofungin displays an inverse concentration-dependent effect. This study has implications for considering the effective doses of antifungal agents used for catheter lock therapy.
