Standardized method for in vitro antifungal susceptibility testing of Candida albicans biofilms.
Candida albicans is implicated in many biomaterial-related infections. Typically, these infections are associated with biofilm formation. Cells in biofilms display phenotypic traits that are dramatically different from those of their free-floating planktonic counterparts and are notoriously resistant to antimicrobial agents. Consequently, biofilm-related infections are inherently difficult to t...
متن کاملResistance of Candida albicans biofilms to antifungal agents in vitro.
Biofilms formed by Candida albicans on small discs of catheter material were resistant to the action of five clinically important antifungal agents as determined by [3H]leucine incorporation and tetrazolium reduction assays. Fluconazole showed the greatest activity, and amphotericin B showed the least activity against biofilm cells. These findings were confirmed by scanning electron microscopy ...
متن کاملIn vitro activity of antifungal combinations against Candida albicans biofilms.
OBJECTIVES The aim of the present study was to evaluate the in vitro activity and synergism of the combinations of amphotericin B/caspofungin and amphotericin B/posaconazole against Candida albicans, grown either as planktonic cells or in biofilms. METHODS Ten C. albicans bloodstream isolates used in this study were collected from intensive care patients admitted to the Vienna University Hosp...
متن کاملAntifungal combinations against Candida albicans biofilms in vitro.
Candida biofilms display increased resistance to most antifungal agents. We have evaluated the efficacy of combinations of fluconazole (FLC), amphotericin B, and caspofungin (CSP) against Candida albicans biofilms in vitro. Indifference was observed for all the combinations of paired antifungal agents when a checkerboard titration method was used. Time-kill experiments revealed an antagonistic ...
متن کاملA 96 well microtiter plate-based method for monitoring formation and antifungal susceptibility testing of Candida albicans biofilms.
Candida albicans remains the most frequent cause of fungal infections in an expanding population of compromised patients and candidiasis is now the third most common infection in US hospitals. Different manifestations of candidiasis are associated with biofilm formation, both on host tissues and/or medical devices (i.e. catheters). Biofilm formation carries negative clinical implications, as ce...
