OBJECTIVES Candidiasis can be associated with the formation of biofilms on bioprosthetic surfaces and the intrinsic resistance of Candida albicans biofilms to the most commonly used antifungal agents has been demonstrated. In this study, we report on the antifungal activity of caspofungin at two different concentrations, on C. albicans and Candida(More)
Immunocompromised patients are at high risk of developing Candida infections. Although cell-mediated immunity is generally believed to play the main role in defence against fungi, antibodies could also be effective in immune defence by different mechanisms of action. The adherence capacity of four strains of Candida albicans to polystyrene and to some(More)
OBJECTIVES Some manifestations of candidiasis are associated with the formation of biofilms on inert or biological surfaces and the intrinsic resistance of Candida albicans biofilms to the most commonly used antifungal agents has been demonstrated. In this study, we report on the influence of the growth of C. albicans in medium containing a sub-inhibitory(More)
This study investigates the influence of treatment of plastic and extracellular matrix (ECM) proteins with chlorhexidine or benzalkonium chloride on subsequent adherence of Candida albicans. Three concentrations were tested for each antiseptic: (i) chlorhexidine, MIC (6.25-12.5 mg/L), 80 x MIC and 800 x MIC; and (ii) benzalkonium chloride, MIC (3.12 mg/L),(More)
Some carbohydrates are known to decrease the attachment of Acanthamoeba sp. to biological surfaces. By a method based on the reduction of a tetrazolium salt (XTT) by the mitochondrial dehydrogenases of the parasites, d-mannose and alpha-d-mannopyranoside have been shown to reduce Acanthamoeba attachment to inert surfaces, indicating that the mannose binding(More)
