Urinary tract infection caused by Corynebacterium urealyticum in a male dog [Infecção do trato urinário por Corynebacterium urealyticum em um cão]

Urinary tract infection (UTI) is one of the most common canine infections, and among the most common indications for antimicrobial therapy. Although a presumptive diagnosis of UTI can be made based on the clinical signs along with a urinalysis, urine culture and sensitivity testing is indicated for the definitive diagnosis as well as for the choice of appropriate antimicrobial therapy (Ling, 2000). Its etiology is generally credited to Gram negative rods as Escherichia coli, Proteus spp. and Klebsiella pneumoniae. Nevertheless, opportunistic microorganisms may also determine UTI, while its role remains to be clearly elucidated.
