Resumo

Urinary tract infections (UTI) are frequent diseases in the routine of clinical medicine of companion animals and bacterial cystitis is the most common cause of UTI in dogs and cats. The bad-formations of the urinary tract, as the ectopic ureter, may predispose the affected animals to recurrent urinary infections caused by the same or different pathogens. Morganella morganii is a bacterium with rare isolation from urinary infections in dogs, and it is considered an opportunistic agent in infectious processes, both in pets as in men. This report aimed to describe the clinical diagnosis, as microbiological diagnosis of this infrequent isolation of this microorganism in a young animal carrier of ectopic ureter. Despite of previous treatments of cystitis, the patient had no clinical improvement due to the lack of correction of the baseline cause, or ectopic ureter; which favored recurrent infections. Even being warned about the diseases and its aggravating, the owner left the treatment of the patient, despite the partial clinical improvement with antibiotic therapy according to the susceptibility profile. The results obtained in this case report confirm the importance of culture and sensitivity test for treatment of UTIs; and the search for baseline causes of infectious processes of the urinary tract. Although it’s rare isolation, Morganella morganii should be considered as an important causative agent of UTI in animals as in humans, since the anatomical deformities favor the rise of pathogens, especially Gram negative inhabitants of the gastrointestinal tract of animals.
