The aim of this research was to determine the occurrence of anti Brucella abortus, anti B. canis and anti Leptospira spp. antibodies in foxes (Pseudalopex vetulus). Sixty road-killed wild foxes from semi-arid of Paraiba state, Northeastern region of Brazil, were used. For the detection of anti B. abortus antibodies, the buffered plate agglutination test (BPAT) was applied as a screening method and the 2-mercaptoethanol test as a confirmatory method. For serological diagnosis of infections by B. canis and Leptospira spp., the agar gel immunodiffusion test (AGID) and the microscopic agglutination test (MAT) were used, respectively. All samples were negative for anti B. canis and anti Leptospira spp. antibodies. Of the 60 foxes tested, 16 (26.6 %) were positive for anti B. abortus antibodies at BPAT, four (6.7%) samples were confirmed in the 2-mercaptoethanol test, and two samples presented titer 100 and two titer 50.
