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

Neosporosis in animals--the last five years.

TL;DR: This review is focused on current status of neosporosis in animals based on papers published in the last five years and strategies for control and prevention are discussed.

What is the global economic impact of Neospora caninum in cattle - the billion dollar question.
TL;DR: This estimate of global losses due to N. caninum, with the identification of clear target markets (countries, as well as cattle industries), should provide an incentive to develop treatment options and/or vaccines.
Journal ArticleDOI
Australian dingoes are definitive hosts of Neospora caninum.
TL;DR: Oocyst shedding from the intestinal tract of a dingo demonstrates that dingoes are definitive hosts of Neospora caninum and horizontal transmission of N.caninum from dingoes to farm animals and wildlife may occur in Australia.

TL;DR: The ecological niches occupied by these species are influenced by a relatively small number of gene products which operate at the host-parasite interface and that the dominance of vertical transmission in N. caninum may be associated with the evolution of reduced virulence in this species.

Immune responses to Neospora caninum and prospects for vaccination.
TL;DR: This article discusses some of the issues and reports on the progress towards a vaccine for neosporosis and suggests vaccination is a feasible option to control the disease.
Journal ArticleDOI
Seroepidemiological evidence for a relationship between Neospora caninum infections in dogs and cattle.
TL;DR: There is a relationship between N. caninum infection of farm dogs and cattle and cattle may be infected by exposure to canine oocysts, since dogs have been shown to be definitive hosts of N.Caninum.

Effect of congenitally acquired Neospora caninum infection on risk of abortion and subsequent abortions in dairy cattle.
Mark Thurmond,Sharon K. Hietala +1 more
TL;DR: Congenitally acquired N caninum infection can cause a substantial number of abortions during the initial pregnancy of heifers, with abortion risk attributable to NCaninum decreasing in subsequent pregnancies, possibly because of selective culling.

Neospora caninum -associated abortion in cattle: the time of experimentally-induced parasitaemia during gestation determines foetal survival

TL;DR: The results suggest that the reason some cows abort is related to the time during gestation when they become infected or an existing infection recrudesces.

Direct production losses and treatment costs from bovine viral diarrhoea virus, bovine leukosis virus, Mycobacterium avium subspecies paratuberculosis, and Neospora caninum.
TL;DR: A sensitivity analysis showed the largest effect on costs was due to milk yield effects, and changing milk production loss from 0 to 5% for BVD increased the costs for the disease by 266%.
