TLDR
By reviewing the scientific literature on N. caninum from a Canadian perspective, culling decisions based on the interpretation of diagnostic tests are more effectively made in the control of N.caninum-associated disease.Abstract:
Neospora caninum is one of the most important causes of abortion in cows. The occurrence of N. caninum infection in beef and dairy cattle has been reported worldwide, and in most provinces in Canada. The objective of this review is to summarize our current understanding of N. caninum in dairy and beef cattle for Canadian bovine practitioners. The review covers the life cycle of the agent, its mechanisms of transmission, clinical signs, and tests for diagnosing the infection. Data on the prevalence of the infection in Canadian dairy and beef cattle are reviewed and briefly compared with estimates from other parts of the world. Most importantly for Canadian bovine practitioners, the impacts of the infection, risk factors for its occurrence, and methods of control are also discussed. By reviewing the scientific literature on N. caninum from a Canadian perspective, culling decisions based on the interpretation of diagnostic tests are more effectively made in the control of N. caninum-associated disease.read more

Epidemiology and Control of Neosporosis and Neospora caninum
TL;DR: 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.

Seroepidemiology of Neospora caninum and Toxoplasma gondii in cattle and water buffaloes (Bubalus bubalis) in the People's Republic of China
TL;DR: The seroprevalence of N. caninum in aborting cows (20.2%) was higher than that in non-aborting cows (16.6%) with an odds ratio of 1.26 (95% CI, 0.54-2.95), but the difference was not statistically significant (P>0.05).

Efficacy of a Neospora caninum killed tachyzoite vaccine in preventing abortion and vertical transmission in dairy cattle.
TL;DR: It was concluded that vaccination after conception prevented 61% abortions in one of five herds and that vaccination may have increased the risk of early embryonic death.

TL;DR: The recent advances made in vaccine development against N. caninum in cattle and in mice are summarized and the most important factors are highlighted, which are likely to influence the degree of protection mediated by vaccination.

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.
Rapid communication Coyotes (Canis latrans) are definitive hosts of Neospora caninum
TL;DR: In this article, four captive-raised coyote pups consumed tissues from Neospora caninum-infected calves and shed Oocysts, which tested positive for N.caninum and negative for Hammondia heydorni using PCR tests.

Coyotes ( Canis latrans ) are definitive hosts of Neospora caninum
TL;DR: Four captive-raised coyote pups consumed tissues from Neospora caninum-infected calves, and one pup shed N. canInum-like oocysts, which tested positive for N.Caninum and negative for Hammondia heydorni using PCR tests.
