Megjegyzések:	Biofilm formation is a relevant risk factor for mortality in candidemia. Data about serum-based susceptibility testing against Candida biofilms are scant; therefore, the activity of fluconazole, amphotericin B, caspofungin and micafungin was determined against Candida albicans and C. parapsilosis biofilms with or without 50% human serum using XTT-based assays. Serum caused a remarkable adverse effect regarding biofilm structure for both species. Additionally, the ratio of nonviable cells increased for C. parapsilosis biofilms, as confirmed by fluorescent microscopy and flow cytometry. Despite impaired biofilm development, traditionally biofilm-active antifungals, surprisingly, showed decreased activity against C. albicans biofilms in serum at concentrations ranging from 0.5 to 1 mg/l and from 0.015 to 1 mg/l for amphotericin B and echinocandins, respectively (P < .01-.05). However, C. parapsilosis showed higher susceptibility to these antifungals due to reduced biofilm mass and the fungicidal effect of serum at concentrations ranging from 0.015 to 1 mg/l and from 0.015 to 512 mg/l for amphotericin B and echinocandins, respectively (P < .01-.05). Fluconazole exerted better antifungal activity in serum than traditionally biofilm-active antifungals against both examined biofilms. For fluconazole, significant differences were observed in susceptibility between serum-treated and serum-free biofilms at concentrations ranging from 0.015 to 8 mg/l and from 0.03 to 512 mg/l for C. albicans and C. parapsilosis isolates, respectively (P < .01-.05). The high antifungal activity of fluconazole in 50% serum both against C. albicans and C. parapsilosis biofilms supports the utility of fluconazole prophylaxis to reduce the risk of catheter-associated fungal infections.
