Neospora caninum

American Association of Bovine Practitioners Conference Proceedings, 2000
Neospora caninum, a protozoal parasite, is a common cause of abortion in dairy cattle in North America. Cows that become infected with Neospora appear to remain infected for life. Infection is acquired through vertical transmission (dam to offspring in utero) or horizontal transmission and leads to endemic abortion, with occasional herds reporting ...

The antigenic composition of Neospora caninum

International Journal for Parasitology, 1999
Neospora caninum is an apicomplexan parasite which causes neosporosis, namely stillbirth and abortion in cattle, and neuromuscular disease in dogs. Although N. caninum is phylogenetically and biologically closely related to Toxoplasma gondii, it is antigenically clearly distinct. In analogy to T. gondii, three stages have been identified. These are: (i)

A review of Neospora caninum and neosporosis

Veterinary Parasitology, 1996
Neospora caninum is a recently recognized protozoan parasite of animals, which until 1988 was misidentified as Toxoplasma gondii. Its life cycle is unknown. Transplacental transmission is the only recognized mode of transmission. It has a wide host range, but its zoonotic potential is unknown.

Neospora caninum in wildlife

Trends in Parasitology, 2006
Neosporosis, which is caused by the coccidian parasite Neospora caninum, is recognized as a major disease of domestic animals that causes high abortion rates in cattle and fatal neurological disease in dogs. A life cycle of N. caninum in wild animals (i.e.

Neospora caninum in birds: A review

Parasitology International, 2018
Neospora caninum is an obligate intracellular protozoan parasite that infects domestic and wild animals. Canids are considered to be definitive hosts since they may shed oocysts into the environment through their feces. The disease is recognized as one of the major causes of bovine abortion worldwide, leading to important economic losses in the dairy ...

Neospora caninum detected in feral rodents

Veterinary Parasitology, 2007
The role of rodents in the epidemiology of neosporosis was investigated by assaying brain tissue of feral mice (Mus musculus) and rats (Rattus norvegicus) for Neospora caninum. Both mouse and rat brain tissue were extracted for total DNA, and subjected to two different N. caninum-specific nested polymerase chain reaction (PCR) assays.

Serological diagnosis of Neospora caninum infection

International Journal for Parasitology, 1999
Since the first isolation of the apicomplexan parasite Neospora caninum, a range of serological assays have been developed for use in dogs, cattle and a variety of other potential host species. The tests include the indirect fluorescent antibody test, the direct agglutination test and different enzyme-linked immunosorbent assays.

Detection of Neospora caninum in semen of bulls

Veterinary Parasitology, 2003
In cattle, transplacental infection is the main route of Neospora caninum transmission, but postnatal transmission by the oral uptake of sporozoite-containing oocysts shed by dogs may also be possible. Other routes of horizontal transmission, such as the venereal route, have not been investigated. In this study, we evaluated the presence of N.

Neospora caninum pneumonia in an adult dog

Journal of the American Veterinary Medical Association, 1995
Neospora caninum was identified in a lung aspirate specimen from an adult dog with severe pneumonia. Neosporosis was tentatively diagnosed by cytologic examination of a Wright-Giemsa-stained smear of the aspirate specimen, using light microscopy. The infection was confirmed by immunohistochemical examination of a section of lung tissue obtained at ...

Neospora caninum (Apicomplexa) in a Stillborn Goat

The Journal of Parasitology, 1992
Tissue cysts of Neospora caninum were found in sections of brain from a stillborn pygmy goat. The tissue cysts had 1-2-microns-thick cyst walls and stained with anti-N. caninum serum in an immunohistochemical test. Glial nodules, mononuclear perivascular cuffing, and foci of inflammation were associated with N. caninum tissue cysts throughout the brain.
