Description
Neosporosis is the disease caused by the intracellular protozoa Neospora caninum. The dog is the definitive host, cattle are the intermediate host and other mamalian species may act as incidental hosts. In the past N.caninum has been confused with T.gondii because they are similar morphologically, but advancements in detection methods has made the two distinguishable.

Transplacental infection results in congenital infection of puppies which is the most typical presentation of the disease. More than 1 puppy in a litter may be affected, although this may not occur simultaneously. Successive litters can be affected, therefore a dam whelping an infected litter should not be allowed to breed again.
Signalment
Puppies are most frequently affected. Hunting dogs are also over represented.
