To determine Neospora caninum seroprevalence in nonvaccinated dairy cattle from the Northern plains of Antioquia. Materials and methods. A cross-sectional study was conducted to determine the prevalence of neosporosis in a major dairy area of Colombia. Blood samples were collected from 1003 dairy cattle in 29 herds located in the municipality of San Pedro de los Milagros, in Antioquia. N. caninum antibody levels were measured by an enzymatic immunoassay (ELISA) and the results classified as positive or negative. Results. Seropositive cattle were observed in all herds, with a prevalence ranging from 7 to 97% and a mean (±S.E) of 37.1% (±4.2). The distribution of seropositive animals by age groups of <1, 1-2, 2-3 and ≥3 years old was 25.5, 30.3, 46.1 and 39.1%, respectively. Conclusions. There is a high seroprevalence of N. caninum in the main dairy cattle area of Antioquia. The large variation among herds suggests the presence of mayor risk factors whose identification would be essential to establish control programs. Considering that any seropositive cow has a greater risk to abort than uninfected mates, future studies should address the epidemiology of abortions that can be attributed to neosporosis and the type of control strategies that could be implemented.http://revistas.unicordoba.edu.co/revistas/index.php/revistamvz/article/view/832/943Neospora caninumcattleseroprevalenceELISAColombia |
