Fatal Case of Brucellosis Misdiagnosed in Early Stages of Brucella suis Infection in a 46-Year-Old Patient with Marfan Syndrome

ABSTRACT We report a fatal case of Brucella suis endocarditis initially misdiagnosed by automated identification systems as Ochrobactrum anthropi infection in a patient with a history of Marfan syndrome and recreational feral swine hunting. This report emphasizes the need to consider brucellosis as a part of the differential diagnosis of acute febrile illness, particularly in patients with known risk of exposure.
