A urinary tract infection as a result of Proteus mirabilis facilitates the formation of kidney stones because the organism:
Proteus mirabilis facilitates the formation of kidney stones because the organism produces a potent urease. Proteus: Causes 1-2% of cases of UTI in healthy women. 5% of cases of hospital-acquired UTI. High prevalence of stones is due to bacterial production of urease (Hydrolyzes urea -ammonia - alkalization of the urine-precipitation of struvite and carbonate-apatite crystals- development of calculi). Option 1: Destruction of blood vessels in the kidney is seen in HUS (Haemolytic uremic syndrome) caused by Enteroheamorrhagic Escherichia coli (EHEC). Option 2: Swarming is the propey of Proteus but not associated with stone formation. Option 3: Proteus is lactose non fermenter ie. does not ferment lactose (sugar).
Systemic Bacteriology (Gram Positive Bacilli, Gram Negative Bacilli)
Destroys blood vessels in the kidney
Exhibits "swarming" motility
Ferments many sugars
Produces a potent urease
