Bluetongue (BT) is an infectious, insect-born viral disease of ruminants. The causative agent of BT is bluetongue virus (BTV) that belongs to the family Reoviridae genus Orbivirus. Insect vectors in the genus Culicoides transmit this virus. BT affects domestic and wild ruminants, however small ruminants are considered the most affected specie. The aim of the study was to detect antibodies against BTV in commercial sheep farms, of the Northeastern region of Sao Paulo State, Brazil. A total of 1002 sera samples collected from adult sheep (above 1 year-old), comprising a total of 31 farms, were screened for the presence of BTV antibodies, by agar gel immunodiffusion test (AGID) and ELISA-CFS (Enzyme Linked Immunosorbent Assay – competitive solid phase), both produced by Pan American Center of FMDV. From a total of 1002 samples, 651 (65%) were positive by AGID and 742 (74.1%), were positive by ELISA-CFS. These results suggest that the BTV is widespread among farms, probably causing subclinical infections.KEY WORDS: AGID, bluetongue virus, ELISA-CFS, seroepidemiological survey.
