RESUMO
Pasteurella species are commensal bacteria of the respiratory airways and oronasal cavity of animals. In this study, we report an unusual case of Pasteurella dagmatis isolation from dog urine with uroliths. An 11-year-old female dog was admitted to the Veterinary Hospital of Ahvaz University complaining of abdominal pain, hematuria, dysuria and stranguria. In clinical and radiological examinations, it was found that abdomen was distended due to urinary bladder obstruction with uroliths. Pasteurella dagmatis was isolated from urine specimen collected by cystocentesis. Finally, uroliths were removed by surgery. Appropriate antibiotic treatment with cephalexin caused improvement. To the best of our knowledge, this is the first report of P. dagmatis presence in dog urine
