Abstract

We report detection of a blaOXA-23-positive Proteus mirabilis clinical isolate through Antimicrobial Resistance Laboratory Network testing that is closely related to OXA-23 producers identified in Europe. Combined with similar reports internationally, this finding suggests that Enterobacterales might serve as a silent reservoir of carbapenemase genes commonly associated with Acinetobacter species.
