Delftia acidovorans Bacteremia in an Intravenous Drug Abuser

Delftia acidovorans (Comamonas acidovorans) is an aerobic, non-fastidious, non-fermentative gram-negative bacillus classified in the Pseudomonas rRNA homology group III that is generally regarded as an environmental organism found in soil and water and as a non-pathogen. We report the first case of systemic D. acidovorans infection in a patient without a long-term immunosuppressive condition where D. acidovorans has been recovered in pure culture as a primary pathogen.
