We evaluated trends in antimicrobial susceptibility in United States hospitals in the 2010 to 2016 period. A total of 8,768 clinical isolates from 47 medical centers were tested for susceptibility by broth microdilution methods. Multidrug-resistant (MDR) and extensively drug-resistant (XDR) rates decreased from 25.7% and 12.4%, respectively, in 2010 to 17.7% and 3.6%, respectively, in 2016. The susceptibilities to most comparator antimicrobial agents increased, whereas the susceptibilities to ceftaroline, levofloxacin, linezolid, and tigecycline remained stable. Ceftaroline retained potent activity against (>99.9%) with no marked variations.
我们评估了 2010 年至 2016 年期间美国医院的抗菌药物敏感性趋势。对来自 47 个医疗中心的 8768 株临床分离株进行肉汤微量稀释法药敏试验。2010 年,耐多药(MDR)和广泛耐药(XDR)的发生率分别为 25.7%和 12.4%,到 2016 年分别下降至 17.7%和 3.6%。大多数比较抗菌药物的敏感性增加,而头孢洛林、左氧氟沙星、利奈唑胺和替加环素的敏感性保持稳定。头孢洛林对 (>99.9%)保持强效活性,无明显变化。
