| why are foley catheters so vulnerable to encrustation and blockage by crystalline bacterial biofilm? | many patients undergoing long-term bladder catheterisation experience blockage and encrustation of their catheters. the problem stems from infection by urease producing bacteria, particularly proteus mirabilis. bacterial biofilms colonise the catheters, the activity of urease raises the ph and induces the deposition of calcium and magnesium phosphate crystals. in this study, a laboratory model of the catheterised bladder has been used to examine the early stages in the formation of the crystalli ... | 2003 | 14574534 |
