Laboratory Exposures from an Unsuspected Case of Human Infection with Brucella canis.

We report a case of human infection with a Brucella canis isolate in an adult in Canada who was receiving a biologic immunomodulating medication. We detail subsequent investigations, which showed that 17 clinical microbiology staff had high-risk exposures to the isolate, 1 of whom had a positive result for B. canis.
