Caprine arthritis encephalitis virus (CAEV) is a retrovirus that infects goats. This study evaluated the prevalence of CAEV in breeder goats from the states of Maranhão, Ceará, Piauí, Alagoas, Sergipe, Rio Grande do Norte, and Paraíba. We collected a total of 531 serum samples from 251 properties. On average, two male breeder goats were examined from each farm. Results from western blotting demonstrated that the prevalence of CAEV was 6.2% (32/513). In each state, the following prevalence values were found Piauí, 5.9% (7/119); Maranhão, 2.0% (01/48); Sergipe, 7.1% (03/42); Alagoas, 17.6% (03/17); Rio Grande do Norte, 4.7% (05/105); Paraíba, 2.1% (02/94); and Ceará, 12.5% (11/34). We also conducted a univariate analysis to determine the risk factors that are associated with CAEV. This analysis revealed that breeding season, records of herd data, criteria adopted for the first mating of females, castration of male goats, origin of breeders, and identification of the animal were associated with CAEV. Adopting control measures to identify CAEV-positive animals and avoid virus transmission to females, especially during breeding seasons, is crucial since, males carrying CAEV can be sources of infection for the entire herd.(AU)
