Abstract

The management of infections with New Delhi metallo-beta-lactamase-1 (NDM)-producing bacteria remains clinically challenging given the multidrug resistant (MDR) phenotype associated with these bacteria. Despite resistance , ceftazidime-avibactam previously demonstrated activity against NDM-positive Herein, we observed synergy with ceftazidime-avibactam and aztreonam against an MDR harboring NDM. , humanized doses of ceftazidime-avibactam monotherapy resulted in >2 log CFU bacterial reduction; therefore, no synergy was observed.

摘要

鉴于产新德里金属β-内酰胺酶-1(NDM)细菌的多重耐药(MDR)表型,对这类细菌感染的管理在临床上仍然具有挑战性。尽管存在耐药性,但头孢他啶-阿维巴坦先前已证明对NDM阳性菌有活性。在此,我们观察到头孢他啶-阿维巴坦与氨曲南对一株携带NDM的MDR菌具有协同作用。然而,人源化剂量的头孢他啶-阿维巴坦单药治疗导致细菌减少>2个对数CFU;因此,未观察到协同作用。
