title: Adherence to urethral catheters by bacteria causing nosocomial infections.
abstract: Previous clinical studies of catheters with hydrophilic coating have, in some instances, shown a delay in the onset of significant bacteriuria, while others reported no such effect. To attempt to determine reasons for these differences we decided to study bacterial adherence of bacteria obtained from nosocomial urinary tract infections associated with catheters. Almost all strains adhered to the silicone catheter and none of them adhered to the catheter with the hydrophilic surface whether incubated in urine or serum. When incubated in urine, all strains adhered to the red rubber catheters. Adherence was variable to the Teflon and elastomer surfaces.
