We report identification of 5 patients with infections caused by NDM-5-producing E. coli harboring PBP3 mutations that showed reduced susceptibility to aztreonam-avibactam and cefiderocol. Durlobactam, a novel diazabicyclooctane β-lactamase inhibitor, demonstrated minimum inhibitory concentrations ranging from 0.5 to 2 µg/mL supporting future investigations into a potential role in clinical management.

在美国,带有青霉素结合蛋白 3 突变的产生 NDM 的大肠杆菌的威胁日益严重——durlobactam 是否有潜在作用?

我们报道了 5 名由产生 NDM-5 的大肠杆菌引起的感染的患者的鉴定,这些大肠杆菌携带 PBP3 突变,这些突变显示出对氨曲南-阿维巴坦和头孢地考的敏感性降低。 Durlobactam 是一种新型二氮杂双环辛烷 β-内酰胺酶抑制剂,其最低抑制浓度范围为 0.5 至 2 µg/mL,支持未来对其在临床管理中的潜在作用的研究。
