Interpretive Summary:

Technical Abstract: Neospora was identified and differentiated from Toxoplasma in tissues from naturally infected dogs. The two groups of organisms cannot be differentiated by light microscope observations and require the electron microscope or special staining techniques utilizing antibody specific for each parasite to tell them apart. Neospora is now known to infect dogs, cats, mice, rats, goats, sheep and cattle. Many abortions have been reported in cattle throughout the U.S. The only known method of infection is from mother to offspring in utero. Clinical signs are predominantly neurological - paralysis leading to death. Some antiprotozoan drugs can be used for treatment. There are no vaccines.
