The antimicrobial susceptibility of canine urinary ( = 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.
测定了一家地区诊断实验室在1年时间内分离出的113株犬尿液菌株的抗菌药敏性。测定了抗菌药物的最低抑菌浓度，并对那些对β-内酰胺类耐药的菌株进行了广谱β-内酰胺酶筛查。结果出人意料，79.6%的菌株对所有测试药物敏感，且未鉴定出超广谱β-内酰胺酶。我们的研究结果表明，用阿莫西林或甲氧苄啶+磺胺甲恶唑等一线药物对犬尿路感染进行经验性治疗可能会成功。
