Outbreak of Extensively Drug-resistant Pseudomonas aeruginosa Associated with Artificial Tears

CDC is collaborating with the Food and Drug Administration (FDA) and state and local health departments to investigate a multistate outbreak of an extensively drug-resistant strain of Pseudomonas aeruginosa. The outbreak strain, carbapenem-resistant Pseudomonas aeruginosa with Verona integron-mediated metallo-β-lactamase and Guiana extended-spectrum-β-lactamase (VIM-GES-CRPA), had never been reported in the United States prior to this outbreak. The outbreak is associated with multiple types of infections, including eye infections. The investigation to date has identified artificial tears as a common exposure for many patients.
