Bacterial Adhesion Capacity of Uropathogenic Escherichia coli to Polyelectrolyte Multilayer Coated Urinary Catheter Surface

The application of catheters to the urinary tract is associated with nosocomial infections. Such infections are one most common types in hospitals and health care facilities can lead numerous medical complications. Therefore, understanding properties catheter surfaces their potential modifications crucial order reduce bacterial adhesion subsequent biofilm formation. In our study, we consider standard polyvinyl chloride (PVC) compare same coated poly(diallyldimethylammonium chloride)/poly(sodium 4-styrenesulfonate) (PDADMA/PSS) polyelectrolyte multilayers. Uncoated were characterized by means roughness, hydrophobicity, zeta measurements. Finally, extent uropathogenic Escherichia coli on bare multilayer was measured. obtained results show that non-treated surfaces, formed which not case for surfaces. PSS-terminated shows lowest could be helpful prevention analysis uncoated reveals significant difference related charge (i.e., potential) examined while roughness hydrophobicity similar. it concluded surface plays role PVC
