Biofilm formation by different Candida species on standard uncoated polyurethane catheters at 24, 48 and 72Â h. Biofilms were quantified colorimetrically by XTT assay, which measures biofilm metabolic activity. Error bars represent the standard deviation among the results for different isolates. Each isolate was tested for its ability to form biofilm at least 6 times
