Insights on seroprevalence of leptospirosis in dogs and cats from people with animal hoarding disorder profile in a semiarid region of Brazil

Abstract

Animal hoarding disorder, especially dogs and cats, is a complex issue that occurs in almost all communities, and it is necessary to collect data that contribute to the understanding of leptospirosis within the One Health initiative. In order to determine the seroprevalence of Leptospira sp., 71 dogs and 39 cats from 33 people with animal hoarding profile in the municipality of Patos, state of Paraíba, semi-arid region of Northeastern Brazil were evaluated by using the microscopic serum agglutination test (MAT) as diagnostic test. Thirty-eight animals (34.5%; 95% CI = 25.7 – 43.4%) were seroreactive, with 46.5% in dogs and 12.8% in cats (P < 0.01), with the highest frequency of the Icterohaemorrhagiae serogroup in both species. The high seroprevalence reported suggests the need for public policies for this vulnerable population in order to prevent the transmission of zoonoses.
