Pasteurella multocida urinary tract infection in a pediatric patient with end-stage renal disease.

Pasteurella multocida is a Gram-negative bacillus that is part of the normal oral flora of cats and dogs. Most infections involving P. multocida are soft tissue infections after animal bites or scratches. We present a case of P. multocida urinary tract infection in a 13-year-old boy with end-stage renal disease receiving peritoneal dialysis. He was successfully treated with intravenous ampicillin-sulbactam followed by oral amoxicillin-clavulanate. Thirteen additional cases of P. multocida urinary tract infection (12 adults and one pediatric patient) reported in the literature were reviewed. Underlying medical illnesses and structural urologic abnormalities are risk factors.
