Abstract


Caprine arthritis encephalitis (CAE) and bluetongue (BT) are viral diseases affecting goats and sheep, respectively, worldwide. Both diseases are characterized by being slow and progressive, causing a variety of clinical signs and determining economic and production losses. The objective of this study was to evaluate the seroprevalence of CAE and BT and its associated factors in dairy and beef goat herds in the state of Paraíba, Northeast Brazil. In total, 6.4% and 1.8% of the animals were positive for caprine arthritis encephalitis and bluetongue, respectively, by Agarose Gel Immunodiffusion assay (AGID). No significant statistical association was found between diseases and risk factors, herd size, age, gender, and type of management in most animals evaluated. The risk factors, production system and grazing of multispecies can influence the prevalence of viral infections in goats in the state of Paraíba.
