Resumo

The introduction of new breeds, aiming at increasing productivity, caused the change in the health profile of herds. Among the diseases introduced in Brazil lentiviroses of small ruminants (LVPR) stand out, represented by caprine arthritis encephalitis (CAE) and the maedi-visna (MV). In order to obtain data concerning the presence of maedi visna (MV) in sheep herds in the microregion of Juazeiro, Bahia, 919 serum samples were evaluated by agar gel immunodiffusion (AGID). The samples were collected in eight cities that make up this microregion (Juazeiro, Sento Sé, Sobradinho, Pilão Arcado, Campo Alegre Lourdes, Remanso, Casa Nova and Curaçá) considering how representative each municipality is within the totalilty of animals. It was observed that 0.34% of the sampled sheep showed positive reaction in the AGID. It was concluded that the MV occurs with low prevalence in the studied microregion, probably due to the predominance of locally adapted breeds.KEYWORDS: AGID; antibodies; Lentivirus; occurrence.
