PREVALÊNCIA SOROLÓGICA DA MAEDI-VISNA EM REBANHOS OVINOS DA MICRORREGIÃO DE JUAZEIRO - BAHIA POR MEIO DO TESTE DE IMUNODIFUSÃO EM GEL DE ÁGAR

Abstract

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, 91 9 serum samples were evaluated by agar gel immunodiffusion (AGID). Thesamples 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 eachmunicipality 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 locallyadapted breeds.
