Brucella suis Biovar 1 isolated from a hepatic abscess drainage.

Positive cultures from hepatic abscess drainage are extremely rare, and in this case the infection would have remained undiagnosed if Brucella suis had not been isolated. Failure to correctly diagnose this zoonosis delays patient treatment and is dangerous, as in this case that could have been a laboratory-acquired disease. This type of infection is preventable if proper safety protocols are established and followed.
