[Adhesion of Escherichia coli rods to urological catheters].
The aim of this study was evaluation of adhesion of E. coli rods to urological catheters made of different synthetic materials. This study included 74 of E. coli strains isolated from urine and blood samples. All of these strains were isolated in the Clinical Microbiology Department of dr A. Jurasz University Hospital in 2003-2006. Analized strains significantly more often adhered to latex catheters than latex catheters covered by silicon and significantly more often adhered to PCV catheters than latex catheters covered by silicon. Four strains were characterized by a strong adhesion to all kinds used urological catheters, used in this study. Among E. coli strains isolated from the blood a higher percentage of strains demonstated adhesion to latex and PCV catheters than in the group of E. coli strains isolated from urine samples (79.3% vs. 68.9% and 69.0% vs. 55.6%, respectively). Out of strains demonstrating the adhesion to urological catheters, the most came from the patients from Clinic of the Nephrology, of Arterial Hypertension and Internal Diseases with the Station of Dialyses. All of lactose-negative E. coli strains adhered weakly to urological catheters.
