Urease hydrolyzes urea to ammonia (NH 3) and thus makes the urine more alkaline. But I thought CLED is meant to prevent the swarming. Proteus mirabilis, a leading cause of catheter-associated urinary tract infection (CaUTI), differentiates into swarm cells that migrate across catheter surfaces and medium solidified with 1.5% agar. Swarming motility was first reported by Jorgen Henrichsen and has been mostly studied in genus Serratia, Salmonella, Aeromonas, Bacillus, Yersinia, Pseudomonas, Proteus, Vibrio and Escherichia. Functional categories of genes differentially expressed during swarming or consolidation. Proteus mirabilis has 16 predicted TCS (Pearson et al., 2008), yet as discussed below, only two (Rcs and Rpp) have been shown to directly play a role in swarming.
