abstract：:Neospora caninum is a cyst-forming parasite that causes abortion in cattle. Despite this parasite's ubiquitous distribution and wide host range, the number of N. caninum isolates obtained to date is limited. In vitro isolation of the parasite is arduous and often unsuccessful. In addition, most isolates have been obta...
