A). Scanning electron microscopy of A) Untreated (control; susceptible and Flu-resistant C. albicans isolates biofilm from urine on the catheter surface at 2 h (a) and 48 h incubation (b, c). Magnification-1000. B) Preformed biofilm of C. albicans treated with ZnO-np. A Preformed biofilm in 2 hours (d) and preformed biofilm after 24 h susceptible and Flu-resistant C. albicans isolates biofilm from urine on the catheter surface treatment of ZnO-np on the catheter surface (e, f). Cells were incubated for 48 h and treated with ZnO-nap was 68 and 100 μg/ml for 24 h. Pre-biofilm the treated was almost real without hyphae and clearly reduced in the number of cells, disruption cell wall is seen in the treated preformed biofilm.
