ABSTRACT
The objective of this work was to verify the frequency of sheep with positive serology for Bluetongue virus in the micro-region of Juazeiro, Bahia State, Brazil. The agar gel immunodifusion test (AGID) was used to examine 469 serum samples of 58 herds. During collection, an epidemiological questionnaire was applied to each farmer. The results demonstrated that 0.43% (2/469) of the analyzed samples presented antibodies for the agent. This region is characterized by a semi-arid climate, and the predominant livestock management system is the extensive one, with a presence of native and crossbred animals, aiming at the production of meat and fleece, with low productivity and technification.
