Case Commentary: When Voldemort Meets Sauron: Treatment Considerations for Emerging Dual-Carbapenemase-Producing Extensively Drug-Resistant Pseudomonas aeruginosa.

Infections caused by extensively drug-resistant Pseudomonas aeruginosa are difficult to treat due to limited effective treatment options. In this issue, a patient with a corneal infection caused by a Verona integron-encoded metallo-β-lactamase (VIM)- and Guiana extended-spectrum β-lactamase (GES)-coproducing P. aeruginosa strain associated with the recent artificial tears-related outbreak in the United States is described. This resistance genotype/phenotype further compromises therapeutic options, and this report provides insights into diagnostic and treatment approaches for clinicians dealing with infections due to this highly resistant P. aeruginosa.
