Cells and Materials
The adhesion of uropathogens to urethral catheters initiates the infectious process which causes morbidity in a large patient population. Catheters were examined by X-ray photoelectron spectroscopy after use in three patients and following incubation in vitro with human urine, urea and creatinine, and found to have adsorbed a conditioning film containing carbon, nitrogen and in some cases phosphorous, calcium and sodium containing components. The binding of three strains of uropathogenic bacteria to the catheter surface was significantly influenced by the suspending fluid composition.
