Popis: ABSTRACT: Canine brucellosisis an infectious disease caused by bacteria of the genus Brucella, with world wide distribution and zoonotic impact, and in humans and animals is a neglected disease. In the present study, the sero prevalence of B. canis and B. abortus were determined in a probabilistic sample of housed dogs from the Atlantic Rainforest area of the state of Paraíba, Brazil, and the factors associated with sero positivity. A total of 386 dogs over three months of age were used. For the search for anti-B.canis antibodies the agar gel immune diffusion test (IDGA) was used as a screening and IDGA+2ME as confirmatory test, and to search for anti-B. abortus antibodies the Rose Bengal test (RBT) test was used. Apparent and real prevalences were calculated, and robust Poisson regression was used to identify factors associated with prevalence. The real prevalence fB. Canis was 12.6% and of B. abortus was 22.8%. The factors associated with sero positivity for B. canis were age greater than 10 years (prevalence ratio; PR = 6.38; P = 0.024) and dogs reared in they ard (PR = 5.20; P = 0.035) and for B. abortus was no treplacement of water of animals everyday (PR = 1.48; P = 0.033). It can be concluded that the prevalence of B. canis and B. Abortus in the region is high, which warns to the adopting of control and prevention measures, as well as greater care in the management of animals, especially for elderly dogs.
