Brucella melitensis is a Gram-negative bacillus that causes a zoonosis that is endemic in Spain. It can be asymptomatic, diagnosed only by positive serological test results, or symptomatic, leading to acute or chronic brucellosis. Chronic brucellosis may present in multiple forms, including osteomyelitis, arthritis, splenic abscess, genitourinary infections, neurological infection (neurobrucellosis), and endocarditis.1 The last form is frequently associated with a poor outcome.1
