Stenotrophomonas maltophilia


See 'Additional Information'

General Information

Gram negative bacilli

It may often be difficult to distinguish colonization from true infection. Stenotrophomonas maltophilia is ubiquitously found in the environment and may also colonize the lower respiratory tract in patients with underlying bronchiectasis.

This pathogen can be isolated from the respiratory tract, and may reflect colonization.

Most common true infections:

  • Line-associated bloodstream infections

  • Hospital acquired and ventilator associated pneumonia
