MaediVisna is a disease caused by a small ruminant lentivirus, with a chronic evolution and, in most cases, unapparent signs. Its diagnosis is based on clinical signs and epidemiological data, with the agar gel immunodiffusion (AGID) test being the classical method for detecting antibodies against lentiviruses. Considering that the state of Tocantins has the potential to develop sheep breeding and that the majority of producers from Colinas do Tocantins city has shown an interest in establishing a rational breeding, this study aimed to determine the prevalence of such disease in that region. A total of 369 blood samples was drawn from sheep bred in several farms of that town, regardless of breed, gender, and age. Every sample underwent an AGID to test for MaediVisna. After the laboratory analyses were concluded, the Fishers exact test was used to evaluate the results against the categories. Also, the odds ratio, with 95% confidence interval, was calculated to check whether age played a role as either a risk or protective factor in these results. It was found that six animals (1.62%) were positive in AGID, therefore concluding that the frequency of seropositivity in that region is low.
