Reporte de caso. Aborto en dos vacas Holstein positivas para Neospora caninum y el virus de la leucosis bovina (VLB) en la Estación Agraria Paysandú de la Universidad Nacional de Colombia.

Abstract

This report describes Neospora caninum and its relationship with the presentation of abortions in cattle; as well as the importance of the definitive hosts (canines), at the moment of the dissemination of the disease within the herd. In addition, the clinical analysis of the disease observed in two cows that presented abortion. In the Paysandú Agricultural Station of the National University of Colombia, Medellín, there was a history of abortion during the years 2021 and 2022, however, in 2023 abortions increased significantly, so it was necessary to investigate this situation in depth. In addition to the abortions, it was found that the individuals studied presented reproductive problems, so serological samples were taken in order to diagnose the etiology causing the abortion. The results obtained showed that the two cows studied were positive for Neospora caninum. Subsequently, serological samples were taken from the canines of the farm, where two individuals were also positive for Neospora caninum. Thus, it was concluded that the canine population was responsible for spreading the disease within the herd, so it is of utmost importance to control these individuals to prevent the spread of Neospora caninum.
