The animals were male and female , over three months old, subdivided in three age groups: < 1 year-old, between 1 and 4 years-old and > 4 years-old. For toxoplasmosis, neosporosis and caprine arthritis-encephalitis diagnosis, were used, respectively, indirect immunofluorescent antibody test (IFATLÃ16), Neospora agglutination test (NATLÃ25) and agar gel immunodiffusion (IDGA, positive or negative). A questionnaire containing reproductive and epidemiologic information was applied for all the farms. All the discussion were realized at 5% significance level. The positivity rates were 23.40 % for the toxoplasmosis and 19.77 % for the neosporosis. Two properties presented no positive result for T. gondii and in one there was no seropositive animal for N. caninum. There were no associations between the frequency of seropositivity and sex for both diseases. A more advanced age influenced positively in the occurrence of anti-T. gondii antibodies, but there no statistical difference for N. caninum. The presence of cats and dogs in farms was associated to the raise of positive rates for toxoplasmosis and neosporosis, respectively. The seropositivity for just one of the agents (T. gondii or N. caninum) did not influence the ocurrence of reproductive failures. There was no association between anti-CAEV antibodies and the presence of antibodies anti-T. gondii or anti-N. caninum... (Complete abstract, click electronic access below)
