Neospora caninum in birds: A review
Parasitology International, 2018Neospora 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 ...

Livestock, 2023
Neosporosis was first identified in the 1980s and has since become well established as an endemic disease of cattle and a significant cause of abortion. Neospora caninum is an obligate, intracellular, protozoal parasite that relies on intermediate and definitive hosts to complete its lifecycle.

Neospora caninum infection in three dogs
Journal of Small Animal Practice, 1995ABSTRACTInfection withNeospora caninumin three young dogs is described. The predominant clinical signs were lower motor neuron deficits of the pelvic limbs, bladder and rectum. In two cases there was liver infection and dysfunction. The younger dogs had an acute onset rapidly progressive syndrome.

Neospora caninum (Apicomplexa) in a Stillborn Goat
The Journal of Parasitology, 1992Tissue 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.

Veterinary Parasitology: Regional Studies and Reports
The seroprevalence and risk factors for exposure to Neospora caninum and Neospora hughesi in broodmares in Ontario were investigated. Sixty of the 219 (27.4%) study broodmares were seropositive for N. caninum and 65/219 (29.7%) for N. hughesi with cut-offs of ≥1:40 and ≥1:160, respectively.

Prevalence of antibodies to Neospora caninum in dogs
Veterinary Parasitology, 1999Serum samples from 1077 dogs suspected of having Neospora caninum infections from 35 states in the United States and 3 provinces in Canada were tested for N. caninum IgG antibodies by the indirect fluorescent antibody test. Antibodies to N. caninum were found in 75 of 1077 (7%) of the samples. Twenty of the positive dogs were females, 17 were males and

Recent advances in Neospora and neosporosis
Veterinary Parasitology, 1999Neospora caninum has emerged as a major cause of abortion in cattle in many countries. This paper reviews recent advances in the life cycle and biology of Neospora with the emphasis on bovine neosporosis. The role of the recently discovered oocyst stage of N. caninum in the epidemiology of neosporosis is discussed.

Serological diagnosis of Neospora caninum infection
International Journal for Parasitology, 1999Since 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, 2003In 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, 1995Neospora 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 ...
