This investigation was carried out in beef cattle (n=219), sheep (n=55), and pampas deer (Ozotoceros bezoarticus) (n=49) from Nhecolândia, sub region of Brazilian Pantanal in Mato Grosso do Sul State, Brazil. It was aimed to assess the seropositivity of these species to bluetongue virus (BTV) by agar gel immunodiffusion test. Seropositivity rates were 42.0% for cattle and 10.9% for sheep. The pampas deer showed to be all seronegative. In cattle, seropositivity to BTV significantly increased with age (P<0.001). These data, the favorable environmental conditions to development of BTV vectors, and the bovine reproductive disorders reported by farmers may indicate that BTV infection occurrs in herds of Brazilian Pantanal, and probably induces to economical losses.(AU)
