Plain-English summary
A dog with a history of bladder stones (urolithiasis) showed signs of a urinary tract infection (cystitis) and was treated with an antibiotic called enrofloxacin, but it didn't help. After further tests, it was found that the bacteria causing the infection were resistant to many antibiotics. The vet performed a procedure to remove the stones and later identified the bacteria as Escherichia coli, which was only sensitive to two specific antibiotics. The dog’s treatment was adjusted accordingly, highlighting the importance of lab tests in effectively treating urinary infections and bladder stones.

Abstract
ABSTRACT Bacterial resistance is a reality in both human and veterinary health, it limits the therapeutic arsenal and raises the costs of the patient’s treatment. A dog with signs of cystitis received treatment with 5mg/kg enrofloxacin at three consecutive times, with low effectiveness. The presence of urethral uroliths was identified and urohydropulsion was done. The animal presented a new obstruction, for which a cystotomy was performed, but continued with signs of infection. Uroculture and antimicrobial susceptibility test were then performed. Escherichia coli was identified, which was resistant to 13 antibiotics, being sensitive only to piperacillin-tazobactam and amikacin. In the screening test for β-lactamase, the production of ESβL was detected. The qPCR indicated the presence of the bla CTXm, bla DHA, bla OXA, bla IMP, bla TEM, bla GIM, bla SIM, bla SPM and bla SME genes, which may lead to a phenotypic resistance profile for ampicillin, amoxicillin-clavulanate, aztreonam, cefepime cefoxitin, cefuroxime, ceftazidime, ceftriaxone, imipenem, and piperacillin-tazobactam. This case reaffirms the value that laboratory analysis adds to the diagnosis and treatment of cystitis and urolithiasis, which can define the direction of evolution of the prognosis and the speed at which the patient's health will be restored.
