Harnessing microbial-derived metabolites in the urinary tract to prevent infection induced catheter encrustation [PDF]

Nature Communications
Proteus mirabilis is a predominant cause of catheter associated urinary tract infection (CAUTI), and a key virulence factor is its urease enzyme which can increase urine pH and form urinary stones, causing catheter blockage and facilitating bacteremia ...

Encapsulation of Urease and Peg-Urease in Erythrocyte [PDF]

Artificial Cells, Blood Substitutes, and Biotechnology, 2000
Erythrocytes can be used to entrap drugs, enzymes or other molecules with active properties, with various encapsulation procedures. The carrier is nonimmunogenic, biodegradable, and circulates freely throughout the body. Urease was covalently immobilized on activated methoxypolyethyleneglycol-5000 (PEG-5000) (1:3 molar ratio).
