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

Maternal immune response in the placenta of sheep during recrudescence of natural congenital infection of Neospora caninum

TL;DR: It is suggested that, similarly to bovine neosporosis, the time of gestation when recrudescence occurs determines the viability of the fetuses and, thus, seems to be related to the severity of lesions and immune response in the placenta.

TL;DR: It was observed that seropositive animals showed cell damage associated with oxidative stress and inflammation, mainly in those with symptomatic infections, which may have influenced N. caninum pathogenesis in symptomatic animals.

High seroprevalance of Neospora caninum in dogs in Victoria, Australia, compared to 20 years ago
Sarah Sloan,Jan Šlapeta,Abdul Jabbar,Jaimie Catherine Hunnam,Bert De Groef,Grant Rawlin,Christina McCowan +6 more
TL;DR: The results demonstrate that exposure to N. caninum in domestic dogs is widespread in Victoria, although faecal oocyst shedding is infrequent, and imply that dogs get either exposed to the infected meat more frequently or that vertical dam to foetus transmission is more frequent than previously thought.
Journal ArticleDOI
Neospora caninum is associated with abortion in Algerian cattle.
TL;DR: A case control study was performed to investigate the link between global seropositivity to N. caninum and abortion risk in cattle farms in Algeria, finding a significant association between seroprevalence and abortion in groups 1 and 3, but not for group 2.

Dogs are definitive hosts of Neospora caninum.

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.

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.
