Proteus species are common intestinal/fecal organisms which are not an
uncommon cause of UTI. They produce urease, which breaks the urea in urine
down to ammonia. This can result in alkaline urine with development of
urinary stones (struvite stones), which can cause renal damage. Any
urinary pathogen can cause damage to the kidney with scarring, especially
in infants, so agressive therapy is important if upper tract infection is
