infection with bacteremia and pneumonia.

species are non-fermentative Gram-negative coccobacilli that are ubiquitous in the environment. The archetype pathogen within the genus is , however, other species have the potential to cause human infection, especially in the hospital setting. We describe a patient with infection due to , a rare agent of human disease, which is often misidentified using biochemical methods. is the source of the Class D OXA-23 carbapenemase that can confer carbapenem resistance in . Therefore, accurate identification of is important for clinical management and to potentially prevent the spread of carbapenem resistance.
