We assessed infections caused by extended-spectrum-beta-lactamase-producing Escherichia coli or Klebsiella spp. treated with piperacillin-tazobactam to determine if the susceptibility breakpoint predicts outcome. Treatment was successful in 10 of 11 nonurinary infections from susceptible strains and in 2 of 6 infections with MICs of >16/4 mug/ml. All six urinary infections responded to treatment regardless of susceptibility.
我们评估了用哌拉西林-他唑巴坦治疗的产超广谱β-内酰胺酶的大肠杆菌或克雷伯菌属引起的感染,以确定药敏折点是否能预测治疗结果。11例由敏感菌株引起的非泌尿系统感染中有10例治疗成功,6例最低抑菌浓度>16/4μg/ml的感染中有2例治疗成功。所有6例泌尿系统感染无论药敏情况如何均对治疗有反应。
