Ochrobactrum anthropi : a rare cause of pneumonia

Ochrobactrum anthropi , a Gram-negative bacillus, is an unusual human pathogen. It has been implicated primarily in catheter-related bloodstream infections. Sporadic cases of infection at other body sites have been reported. Pneumonia, however, is an exceedingly rare clinical manifestation; only one case has been reported in the medical literature so far. We present another case of lower respiratory tract infection secondary to O. anthropi in a patient who was critically ill, but recovered with a favorable outcome. We have provided an overview of clinical manifestations, diagnosis, and treatment of infections due to this rare microorganism.
