Cefiderocol (FDC) is a recently developed siderophore cephalosporin showing excellent antibacterial activity against Gram-negative bacteria, including Acinetobacter baumannii. By investigating a series of A. baumannii clinical isolates with elevated MICs of FDC, we showed that PER-like β-lactamases and, to a lesser extent, NDM-like β-lactamases, significantly contributed to reduced susceptibility to that antibiotic. Interestingly, we showed that combination of FDC with avibactam exhibited excellent activity against all multidrug-resistant isolates coproducing OXA-23 and PER-type β-lactamases.
头孢地尔(FDC)是一种新开发的铁载体头孢菌素,对革兰氏阴性菌(包括鲍曼不动杆菌)具有优异的抗菌活性。通过研究一系列 FDC 药敏MIC 升高的鲍曼不动杆菌临床分离株,我们发现 PER 样β-内酰胺酶,以及在较小程度上,NDM 样β-内酰胺酶,显著降低了对该抗生素的敏感性。有趣的是,我们发现 FDC 与阿维巴坦联合使用对所有同时产 OXA-23 和 PER 型β-内酰胺酶的多药耐药株均具有出色的活性。
