Closed sterile catheter drainage has markedly reduced the incidence of nosocomial urinary tract infections. Infections that occur during closed drainage must ascend by colonizing the catheter or urethra. Our study compared adherence by different bacterial species to different catheter surfaces. We found no bacteria adhering to the hydrophilic catheter surface. Of the gram-negative bacteria Proteus mirabilis showed the greatest adherence to the other catheters and it, like most bacteria, showed the most marked adherence to the red rubber catheter.
封闭式无菌导管引流显著降低了医院获得性尿路感染的发生率。在封闭式引流过程中发生的感染必须通过在导管或尿道定植而上行。我们的研究比较了不同细菌种类对不同导管表面的黏附情况。我们发现没有细菌黏附在亲水性导管表面。在革兰氏阴性菌中，奇异变形杆菌对其他导管的黏附性最强，并且与大多数细菌一样，它对红色橡胶导管的黏附最为明显。
