Epidemiology and Control of Neosporosis and Neospora caninum
TLDR
This review is focused mainly on the epidemiology and control of neosporosis in cattle, but worldwide seroprevalences of N. caninum in animals and humans are tabulated.Abstract:
Neospora caninum is a protozoan parasite of animals. Until 1988, it was misidentified as Toxoplasma gondii. Since its first recognition in dogs in 1984 and the description of the new genus and species Neospora caninum in 1988, neosporosis has emerged as a serious disease of cattle and dogs worldwide. Abortions and neonatal mortality are a major problem in livestock operations, and neosporosis is a major cause of abortion in cattle. Although antibodies to N. caninum have been reported, the parasite has not been detected in human tissues. Thus, the zoonotic potential is uncertain. This review is focused mainly on the epidemiology and control of neosporosis in cattle, but worldwide seroprevalences of N. caninum in animals and humans are tabulated. The role of wildlife in the life cycle of N. caninum and strategies for the control of neosporosis in cattle are discussed.read more

Peripheral white blood cell counts throughout pregnancy in non-aborting Neospora caninum-seronegative and seropositive high-producing dairy cows in a Holstein Friesian herd
B. Serrano,Sonia Almería,Irina Garcia-Ispierto,Jesús Yániz,Ahmed Abdelfattah-Hassan,Fernando López-Gatius +5 more
TL;DR: A parity-associated effect of chronic N. caninum infection was observed on peripheral blood cell profiles in dairy cattle during gestation, with lower levels of total leukocytes, lower neutrophil and higher monocytes recorded in primiparous Neospora-seropositive cows.

A Descriptive Study of Lectin Histochemistry of the Placenta in Cattle following Inoculation of Neospora caninum.

TL;DR: It is shown that there is a distinctive pattern of lectin binding in the placenta of cattle infected with N. caninum, and the direct effect of the presence of the protozoa as well as the altered expression of cytokines could explain these changes in the maternofetal interface.

Oxidative stress in brain tissue of gerbils experimentally infected with Neospora caninum.

TL;DR: The results suggest that the oxidative stress occurs at both time points, but the patterns of the biomarkers are different.

Use of ELISA based on NcSRS2 of Neospora caninum expressed in Pichia pastoris for diagnosing neosporosis in sheep and dogs.

TL;DR: The results from this study suggest that the recombinant protein expressed in P. pastoris is a suitable antigen for use in immunodiagnosis to detect N. caninum in two important species exposed to this parasitosis.
Journal ArticleDOI
Seroprevalence of Neospora caninum Infection on Dairy Cattle in Farms from Southern Romania
TL;DR: This study indicates that N. caninum infection is widespread in the south of Romania, which could explain the causes of abortions registered in some herds in the studied area.

TL;DR: Dogs are a definitive host of Neospora caninum, and mice inoculated with canine faecal extracts were monitored for evidence of neosporosis using a variety of morphologic, immunohistologic, serologic, and genetic analyses.

A review of Neospora caninum and neosporosis
TL;DR: Neospora caninum is a recently recognized protozoan parasite of animals, which until 1988 was misidentified as Toxoplasma gondii, and its life cycle is unknown.

Newly recognized fatal protozoan disease of dogs
TL;DR: A newly identified parasite, Neospora caninum, structurally distinct from T gondii, was found in 10 dogs and formed meronts in many tissues of the dogs, especially the brain and spinal cord.

Review of Neospora caninum and neosporosis in animals.
TL;DR: Information on biology, diagnosis, epidemiology and control of neosporosis in animals, a major cause of abortion in cattle in many countries, is reviewed.

Neonatal Neospora caninum infection in dogs: isolation of the causative agent and experimental transmission.
TL;DR: Neospora caninum infection was diagnosed in 5 young dogs from 2 litters with a common parentage that developed hind limb paresis 5 to 8 weeks after birth and was isolated in cell cultures, mice, and dogs inoculated with infected canine tissues.
