Title

Influence of ZnO nanoparticles on Candida albicans isolates biofilm formed on the urinary catheter

Pages

  424-432

Abstract

 Background and Objectives: The aim of this study was to determine the effect of zinc oxide nanoparticle (ZnO-np) solu-tion in the surface Catheter on C. albicans adhesion and Biofilm formation. Materials and Methods: Out of 260 isolates from urinary Catheter, 133 were determined as C. albicans by common phe-notypic and genotyping methods. ZnO nanoparticles with 30 nm were made by the sol-gel method, which was confirmed by XRD (X-ray diffraction) and scanning electron microscope (SEM) methods. Candidal adhesion and Biofilm assays were per-formed on Catheter surfaces for 2 and 48 hours, respectively. The effect of sub-MIC (minimum inhibitory concentrations) and MIC concentrations of ZnO-np on Biofilm formation was evaluated after 24 hours using Crystal violet (CV), colony-forming unit (CFU), and SEM. Results: Out of 133 C. albicans isolates, 20 (15%) fluconazole-resistant and 113 (85%) susceptible isolates were determined by the disk diffusion method. Results showed that both isolates adhered to Biofilm formation on the Catheter surfaces. A significantly (P< 0. 05) higher number of CFUs was evident in fluconazole-resistant Biofilms compared to those formed by susceptible isolates. ZnO-np reduced Biofilm biomass and CFUs of dual isolate Biofilms (P< 0. 05). ZnO nanoparticles had a significantly (P< 0. 05) greater effect on reducing fluconazole-resistant C. albicans Biofilm biomass compared to susceptible isolates. Conclusion: Zno-np exhibits inhibitory effects on Biofilms of both isolates. These findings provide an important advantage of ZnO that may be useful in the treatment of Catheter-related Urinary tract infection.
