Stress-driven stage transformation of Neospora caninum

Parasitology Research, 2010
Neosporiosis, a serious disease caused by the apicomplexan intracellular parasite Neospora caninum, is considered to be one of the most economically important diseases in cattle. It is associated with potentially serious complications such as abortion, stillbirth and maternal infertility.

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 (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.

Neospora caninum and Milk Production

American Association of Bovine Practitioners Conference Proceedings, 2001
Recent research on Neospora caninum infection in dairy cattle and its effect on milk production has yielded conflicting results, ranging from positive to negative effects. These differences may be related to experimental factors such as study design, sample selection criteria, statistical techniques, or an as-yet undetermined biological effect.

Vertical Transmission of Neospora caninum in Dogs

The Journal of Parasitology, 1995
Herein we report the development of a canine model to examine transplacental and/or transmammary transmission of Neospora caninum. Six pregnant bitches were experimentally infected with N. caninum on day 21 of gestation. One bitch successfully delivered a litter of 3 live pups.

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 infection dynamics in dairy cattle

Parasitology Research, 2012
Neospora caninum is considered in many countries as one of the key abortion agents in cattle. This study aims to investigate the parasite behavior in dairy cattle in the municipality of Avaré, SP, Brazil, where abortions frequently occur. An ELISA was performed to compare two samplings on a total of 615 animals; tests were performed in the same herds ...

Neospora caninum (Protozoa: Apicomplexa) Infections in Mice

The Journal of Parasitology, 1989
Groups of mice were given 0 mg, 4 mg, or 2 mg of methylprednisolone acetate (MPA) 7 days prior to, the day of, and 7 days after subcutaneous inoculation with 0 or 2 x 10(5) tachyzoites of Neospora caninum. Clinical signs of disease were seen only in mice given both MPA and N. caninum tachyzoites. Mice given 4 mg MPA and N. caninum tachyzoites developed

Neospora caninum: oocyst challenge of pregnant cows

Veterinary Parasitology, 2002
Three pregnant cows were each orally challenged at 10 weeks of gestation with 600 sporulated oocysts of Neospora caninum. The number of oocysts was limited by those available. In concurrent bioassays, one oocyst per os infected each of two gerbils. Challenged cattle developed Neospora-specific antibody, cell proliferation and gamma-interferon responses.
