isolates ( = 1,909) were collected from 70 U.S. medical centers, and their susceptibilities were tested using the broth microdilution method. Ceftazidime-avibactam (MIC/MIC, 2/8 mg/liter) and ceftolozane-tazobactam (MIC/MIC, 0.5/2 mg/liter) were the most active (i.e., had the highest susceptibility rates) compounds after colistin, with national susceptibility rates of 96.9% and 97.5%, respectively. Overall, piperacillin-tazobactam (MIC/MIC, 4/128 mg/liter) and meropenem (MIC/MIC, 0.5/16 mg/liter) were active against 77.5% and 76.0% of the isolates, respectively. Susceptibility variations across census divisions were documented for many antimicrobials.
从 70 家美国医疗中心采集了 1909 株分离株,并采用肉汤微量稀释法检测它们的药敏性。头孢他啶-阿维巴坦(MIC/MIC,2/8 毫克/升)和头孢洛扎-他唑巴坦(MIC/MIC,0.5/2 毫克/升)在粘菌素之后是最有效的(即具有最高的敏感性率)化合物,其全国敏感性率分别为 96.9%和 97.5%。总体而言,哌拉西林-他唑巴坦(MIC/MIC,4/128 毫克/升)和美罗培南(MIC/MIC,0.5/16 毫克/升)对分别 77.5%和 76.0%的分离株具有活性。许多抗菌药物在普查区之间都有记录到药敏性的变化。
