OXA beta-lactamases from Acinetobacter spp. are membrane-bound and secreted into outer membrane vesicles

Lucia Capodimonte, Fernando Teixeira Pinto Meireles, Guillermo Bahr…·Alejandro J. Vila

This paper identifies membrane-bound OXA beta-lactamases in Acinetobacter spp. and shows they are secreted into outer membrane vesicles, contributing to antimicrobial resistance.
