Cross-sectional study of Leptospira spp. and Brucela abortus in goat herds from Paraná state, Brazil

Background: Leptospirosis and brucellosis are zoonosis worldwide distributed that have great economic importance, especially in goats. This study aimed to carry out a cross-sectional study to determine the prevalence of anti-Leptospira spp. and anti-Brucella abortus antibodies and to determine epidemiological variables associated to infection by these ethiological agents in goats. Materials, Methods & Results: Serum samples were collected from 1055 goats of 95 properties distributed in 18 regional centers of Paraná State from April to August of 2010. Collected samples were submitted to microscopic agglutination test (MAT) for the detection of anti-Leptospira spp. antibodies with 22 reference serovars: Australis, Bratislava, Autumnalis, Butembo, Castellonis, Bataviae, Canicola, Fortbragg, Whitcombi, Cynopteri, Grippotyphosa, Hebdomadis, Copenhageni, Icterohaemorrhagiae, Panama, Pomona, Pyrogenes, Hardjo, Wolffi, Shermani, Tarassovi and Londrina 1 (L1). The samples were also submitted to buffered acidified plate antigen test (BAPA) and 2-mercaptoethanol test (2-ME) to detect anti-Brucella abortus antibodies. The results obtained from epidemiological and serological study were analysed by Epi Info 3.5.3. We observed 9.9% (104/1055) of goats reagents in at least one serovar of Leptospira spp. and no reagent animal to Brucella abortus. The variables that were statistically [...](AU)
