Neospora caninum is a coccidian parasite that was identified as a species in 1988. Prior to this, it was misclassified as Toxoplasma gondii due to structural similarities. [ 1 ] The genome sequence of Neospora caninum has been determined by the Wellcome Trust Sanger Institute and the University of Liverpool . [ 2 ]
Neospora is a single celled parasite of livestock and companion animals. It was not discovered until 1984 in Norway , where it was found in dogs . Neosporosis , the disease that affects cattle and companion animals, has a worldwide distribution.
Jitender P. Dubey (born July 15, 1938) is a veterinary parasitologist and microbiologist who pioneered the control and diagnosis of Toxoplasma gondii (T. gondii), Neospora caninum, and Sarcocystis neurona. [1] Dubey discovered the life cycle of Toxoplasma gondii, and discovered and named both Neospora caninum and Sarcocystis neurona. [2]
Some wolves carry Neospora caninum, which can be spread to cattle and is correlated with bovine miscarriages. [6] Among flukes, the most common in North American wolves is Alaria, which infects small rodents and amphibians which are eaten by wolves. Upon reaching maturity, Alaria migrates to the wolf's intestine, but does little harm.

Neospora hughesi was considered the same parasite as Sarcocystis neurona, Neospora spp. (including N. caninum), and Toxoplasma gondii until the 1970s, when innovations in macromolecular analysis suggested phenotypic and molecular differences, which resulted in the divergence of species. [4]
Genus Neospora has one important species, N. caninum, which affects dogs in a manner similar to toxoplasmosis. Neosporosis is difficult to treat. [9] Genus Hepatozoon contains one species that causes hepatozoonosis in dogs and cats, H. canis. Animals become infected by ingesting an infected brown dog tick (Rhipicephalus sanguineus).

Sheep and goats are both small ruminants with cosmopolitan distributions due to their being kept historically and in modern times as grazers both individually and in herds in return for their production of milk, wool, and meat. [1]
