Brucellosis as an Unusual Cause of Mitral Infective Endocarditis

Brucellosis is a world-wide zoonosis and systemic disease affecting various organs. The causative organism is an intracellular proteobacteria gram-negative bacillus of the genus Brucella. Human brucellosis is a multi organ disease, transmitted via unpasteurized animal milk and cheese. A renewed scientific interest in human brucellosis has be enfueled by its recent reemergence [1,2]. Symptoms are nonspecific including fever, sweating, malaise, headache, back pain, loss of appetite and they can develop suddenly, evenly or over a week period. Involvement of any organ is often referred as localized disease and can be assessed as a complication of acute brucellosis or manifestation of chronic brucellosis [3,4]. Brucellosis endocarditis (BE) is rare but it is the cause of death in 80% of cases with brucellosis.
