Delftia Acidovorans: A Rare Pathogen in Immunocompetent and Immunocompromised Patients

Abstract

Delftia acidovoransis an aerobic, nonfermenting Gram-negative bacillus. It is usually a nonpathogenic environmental organism and is rarely clinically significant. AlthoughD acidovoransinfection most commonly occurs in hospitalized or immunocompromised patients, there are also several reports documenting the infection in immunocompetent patients. The present article describes a B cell lymphoblastic leukemia patient withD acidovoranspneumonia who was successfully treated with antibiotic therapy. The present report indicates that unusual pathogens may be clinically significant in both immunocompromised and immunocompetent patients.D acidovoransis often resistant to aminoglycosides; therefore, rapid detection of this microorganism is important.
