Antibody was detect by indirect immunofluorescence (IFI), with the cut-off of 1:200. Data were analyzed using descriptive and inferential statistics and frequency distribution. The variables questioned was analyzed first by a univariate logistic regression to evaluate the association between abortion history and general management practices used in the farm with seropositive animals were selected for multivariate analysis if P 0.05) for all other variables questioned and its association with seropositive animals.
