This study evaluated the presence of circulating antibodies of anti-Brucella canis and anti-B. abortus in shelter dogs maintained in four cities of Northern Paraná. Serum samples of 100 dogs, of both sexes, from the cities of Apucarana, Arapongas, Londrina and Rolândia were collected for the determination of the serological presence of B. canis by the utilization of agarose gel immunodiffusion and B. abortus by the buffered acidified antigen assay. Only 4% (4/100) of the samples evaluated demonstrated seroreactivity to B. canis, with seropositivity varying between 4.17 10%. However, positive samples originated only from the cities of Apucarana (4.17%; 2/48) and Londrina (10%; 2/20). Seroreactivity to B. abortus antibodies was not verified within the canine population evaluated. These results suggest that B. canis is circulating within the dog population of Northern Paraná.
