From: Anti-Candida activity of antimicrobial impregnated central venous catheters
In vitro biofilm formation on central venous catheters. Distinct Candida species were allowed to form biofilm for 24, 48 and 72 h in segments of three different CVCs: standard uncoated polyurethane CVC (PU), minocycline-rifampin impregnated CVC (MR) and second-generation chlorhexidine/silver sulfadiazine-impregnated (CSS). Graphics show the results for the two isolates of C. albicans (a), C. glabrata (b) and C. parapsilosis (c). 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. * P < 0.05 of coated catheters when compared with PU at each time point
