Neospora Testing


  • Abortions associated with Neospora occur mid-gestation. Dogs are definitive hosts, capable of shedding oocysts in feces after eating infected tissue. Oocysts are able to survive in soil and water beyond the decomposition of the feces. Cattle become infected by ingesting oocysts.
  • Infection can also pass vertically from dam to fetus in cattle

Sample Types


  • Test individuals or groups of aborting and non-aborting cows to associate Neospora with abortions


  • Available within 5 days of sample receipt
  • Reported as Positive or Negative
  • Additional diagnostic evaluation may be necessary with a positive result.
  • To investigate Neosporosis as a cause for abortions in a herd, quantitative group comparisons between ‘aborting’ and ‘non‐aborting’ groups is recommended. If a statistically significant association exists between a positive antibody response in the ‘aborting’ group compared to the ‘non‐aborting’ group, it is highly probably that N. caninum is an active cause for abortion in the dairy herd.
  • Probability values less than 0.10 indicate a likely causative relationship.

Testing Supplies

CentralStar’s laboratories provide sample analyses on milk, blood, fecal, and tissue samples for a variety of production, disease and health-related traits. More than 6 million samples are processed annually using state-of-the-art equipment and techniques including infrared spectroscopy, flow cytometry, ELISA, PCR, and more.

Diagnostic tests are intended to identify diseases for animal health, and do not determine the “safety” of milk.
