Functional export of NDM-7 to outer membrane vesicles in Klebsiella pneumoniae compromises imipenem and cefiderocol activity

A Pedro González, Valeria E Quiroz, Katherine Soto, Christina Maria Anna Pia Schuh, Lorena Díaz, César A. Arias, Alejandro J. Vila, Jose Manuel Munita, Carolina López

This study shows that NDM-7 carbapenemase is exported to outer membrane vesicles in Klebsiella pneumoniae, enabling extracellular antibiotic degradation and conferring resistance to imipenem and cefiderocol.
