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

Neospora caninum tachyzoite immunome study reveals differences among three biologically different isolates
Javier Regidor-Cerrillo,Paula García-Lunar,Iván Pastor-Fernández,Gema Álvarez-García,Esther Collantes-Fernández,Mercedes Gómez-Bautista,Luis Miguel Ortega-Mora +6 more
TL;DR: Differences in the immunome profiles rely on the immune response induced by each isolate and that these differentially recognized antigens could be investigated as putative virulence markers of neosporosis.

First in vitro isolation of Neospora caninum from a naturally infected adult dairy cow in Slovakia
TL;DR: The impact of in vitro isolation and molecular characterisation of Neospora caninum as well as sequence analyses was studied and the first Slovak isolate was sequenced and published in GenBank under accession number GU300774.
Journal ArticleDOI
Low rates of Neospora caninum infection reactivation during gestation are observed in both chronically and congenitally infected mice.
TL;DR: Low rates of reactivation of N. caninum infection were induced in chronically infected mice and decreased in subsequent generations regardless of the isolate employed in the inoculations, thus, further studies are needed to improve this reactivation mouse model.

Neospora caninum: Seroprevalence in beef cattle in the mountainous region of Santa Catarina, Brazil
Mayckon Antonio Cardoso Padilha,Gefferson Wasen,Antonio Pereira de Souza,Viviane Milczewski,Thaís Vaz Brito da Luz,Amélia Aparecida Sartor,Juliana Antunes Farias,Anderson Barbosa de Moura +7 more
TL;DR: Results indicate that infection by N. caninum in beef cattle is widespread in the studied region and higher seroprevalence was observed among older females.

TL;DR: In this article, a questionnaire that investigates the epidemiological aspects of neosporosis was used in the analysis of risk factors associated with the animal-level and herd-level prevalence in dairy cattle.

Dogs are definitive hosts of Neospora caninum.
Milton M. McAllister,Jitender P. Dubey,David S. Lindsay,Jolley Wr,Rebecca A Wills,McGuire Am +5 more
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.
