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.

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.

Transplacental Neospora caninum Infection in Cats

The Journal of Parasitology, 1989
Transplacental transmission of Neospora caninum was studied in 2 pregnant cats (queens). Queen 1 was inoculated subcutaneously with 2 x 10(6) cell culture-derived N. caninum tachyzoites on day 47 of gestation. She gave birth to a full-term kitten on the 17th day after inoculation. The kitten died the second day after birth due to generalized N. caninum

Neospora caninum infection in three dogs

Journal of Small Animal Practice, 1995
ABSTRACTInfection 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, 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.

Prevalence of antibodies to Neospora caninum in dogs

Veterinary Parasitology, 1999
Serum 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

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 ...
