Neospora
''Neospora'' is an important protozoan pathogen in cattle and dogs. It was not discovered until 1984 in Norway, where it was found in dogs. It is highly transmissible and some herds can have up to a 90% prevalence. ''Neospora'' causes abortions in cattle and up to 33% of pregnancies can result in aborted fetuses on one dairy farm. Diagnosis is hard because the parasite is not found in adults. The best way to detect the parasite is by its pathological effects on fetuses. ==Life cycle==
The life cycle is similar to ''Toxoplasma''. An infected dog will pass the oocysts through its feces and infect food or water. A cow or other animal will then up take the parasite. The parasite will undergo asexual reproduction in the animal's muscle until it is eaten by a dog. There, sexual reproduction will occur and oocysts will be created and passed through the feces.
