Misidentification of Brucella suis as Ochrobactrum anthropi in a Patient with Septic Arthritis

We report a case of a 24-year-old resident of North Queensland who presented to our facility with a native joint septic arthritis. A bacterial isolate recovered from an initial joint aspirate culture was misidentified as Ochrobactrum anthropi using an automated identification system. A subsequent specimen grew an isolate that was identified as Brucella sp. by the same automated system, with a single biochemical reaction (adonitol) differentiating the identities of the two organisms. Subsequent real-time PCR testing of the IS711 element of the Brucella genome confirmed both isolates as Brucella suis.
