Antimicrobial resistance and beta-lactamase production ofEscherichia colicausing canine urinary tract infections: Passive surveillance of laboratory isolates in Saskatoon, Canada, 2014.
The antimicrobial susceptibility of canine urinaryEscherichia coli(n= 113) isolated by a regional diagnostic laboratory over a 1-year period was determined. Antimicrobial minimum inhibitory concentrations were determined, and those isolates resistant to beta-lactams were screened for broad-spectrum beta-lactamases. Isolates were unexpectedly susceptible, 79.6% were susceptible to all drugs tested and no extended-spectrum beta-lactamases were identified. Our findings indicate that empiric treatment of canine urinary tract infections with first line drugs such as amoxicillin or trimethoprim + sulfamethoxazole is likely to be successful.
