Brucella canis and other species of the genus Brucella can cause human disease. However, this species infrequently cause human disease, including in countries where dogs population is highly infected. A 15 years old male was admitted to the hospital with 15 days history of fever without visible focus. Physical examination revealed pain at liver palpation and axillar, cervical and inguinal lymphoadenomegalies. Abdominal ultrasonography showed spleenomegally, the chest Rx and the trans thoracic echocardiogram were normal. Five blood samples were obtained and cultured in 2 standards bottles (time of positivization 72 - 64,8 hours), and 3 pediatric FAN bottles (time of positivization 74,5; 72 and 67,2 hours) (Bact-Alert sistem, Biomerieux, Marcy, l’Etolie, France). The microorganism was presuntive identified as B. canis, and then was confirmed in the National Reference Center Instituto ANLIS «Carlos G. Malbran». After 14 days of initiating ceftriaxone treatment the patient was afebrile. When the confirmation of Brucella was made, he was discharged and ambulatory was prescribed with doxycycline and rifampin for 21 days. Bones were not compromised and the outcome was good with complete resolution of his illness.
