| Abstract: | The adhesion and biofilm formation of Pseudomonas aeruginosa strains on the surface of catheters made of various polymers (PU, SL, PCW) were determined in vitro. It was used the method by Richards et al. with modification of Rózalska et al. (1998), in which soluble colourless TTC is reduced to insoluble red formazan. The results of this study indicate that 80.3% of this strains adhered and 94.6% formed biofilm on the Nelaton catheter, 86% strains adhered and 76.1% formed biofilm on the polyurethane catheter, and 73.2% strains adhered, and 78.9% formed biofilm on the Foley catheter. |
