In order to analyze the occurrence of antibodies to Brucella ovis in sheep in a semi-arid region, this survey was conducted in the micro-region of Juazeiro, Bahia State, Brazil. The agar gel immunodifusion test (AGID) was used to examine 694 serum samples of 58 flocks. Antibodies to B. ovis were found in 5 (0.72%) of the investigated animals. It is believed that this low number of positive cases is related to the characteristics of the production. The predominant system is the extensive one, with presence of locally adapted breeds and crossbred animals, aiming at the production of meat and skin, with low productivity rates and technical development.
