A Sensor To Detect the Early Stages in the Development of CrystallineProteus mirabilisBiofilm on Indwelling Bladder Catheters

A simple sensor has been developed to detect the early stages of urinary catheter encrustation and avoid the clinical crises induced by catheter blockage. In laboratory models of colonization by Proteus mirabilis, the sensor signaled encrustation at an average time of 43 h before catheters were blocked with crystalline biofilm.
