 Caused by the protozoan parasite ''[[Neospora|Neospora caninum]]'' and is the commonest cause of abortion in dairy cattle. ''Neospora caninum'' is similar to ''[[Toxoplasma gondii]]'' and although the complete life cycle of the protozoa is unknown, the dog has been found to be the definitive host.

 Stillborn calves can be born from infected dams and congenitally infected calves may be  born with encephalomyelitis. Abortion usually occurs between 5-7 months of gestation but can occur as early as 3 months.

 The histological appearance of lesions on an aborted fetus can be enough to confirm a diagnosis.
 Additionally antibodies to the protozoa can be identified via serological methods.

-To avoid the transmission of Neospora caninum oocysts from dogs to cattle, dogs should not be allowed access to calving cows, placental membranes and aborted or dead calves. Dogs should also be stopped from defecating in cattle feeding areas.

 Non-suppurative encephalitis is most commonly seen in aborted foetuses. Additionally non suppurative [[Myocarditis|myocarditis]], myositis and widespread non suppurative infiltrates in other organs are often found. Tissue cysts will be present and can be identified.
 Hepatitis may also be found in epidemic abortions.
