Ochrobactrum anthropi septic arthritis of the acromioclavicular joint in an immunocompetent 17 year old.

Ochrobactrum anthropi is a ubiquitous, aerobic, gram-negative bacillus of low virulence, most frequently associated with nosocomial infections and infections related to indwelling catheters in immunocompromised hosts. This article presents the first reported case of O anthropi septic arthritis, here occurring at the acromioclavicular joint of an otherwise healthy patient, and provides treatment recommendations based on our experience.
