E-mail: [e-mail] The neosporosis is considered a major cause of neonatal mortality and abortion in cattle, causing great economic and reproductive losses. The aim of this study was to investigate the occurrence of antibodies against N. caninum in dairy cattle in Concordia, which is considered one of the biggest milk producers in the Santa Catarina state. 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. Therefore, in this study it can be concluded that the dairy cattle from this region in study are potentially exposed to infection by N. caninum.
