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 caninum is a major pathogen of cattle and dogs that occasionally causes clinical infections in horses, goats, sheep, and deer as well. The domestic dog is the only known definitive host for N. caninum.
The most common is Ancylostoma caninum, followed by Uncinaria stenocephala and A. braziliense. Signs include diarrhea, vomiting, and weight loss. [6] Tapeworms* are also common and in the dog are usually Dipylidium caninum, which is spread by ingesting fleas and lice. Also common is Taenia pisiformis, spread by ingesting rabbits and rodents.
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). Symptoms ...
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]
In addition, A. caninum can also cause intestinal inflammation with signs of an acute abdomen. [84] [85] Of the filariae, the heartworm (Dirofilaria immitis) and Dirofilaria repens are zoonotic agents. D. immitis rarely causes disease in humans, although about 20% of the population in endemic areas have antibodies. In most cases, larval ...

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.
