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

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.

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.

TL;DR: Oocysts, brain/cerebellum and medulla specimens of Dog 1 proved positive by a PCR assay targeting the Nc-5 gene of N. caninum, and the PCR products of ITS1 were sequenced, confirming the isolate as N.Caninum.

The Use of Beef Bull Semen Reduced the Risk of Abortion in Neospora-seropositive Dairy Cows
TL;DR: The results indicate that the use of beef bull semen can reduce the risk of abortion in dairy cows, and suggest that annual screening for neosporosis, specifically the antibody titre to the protozoan, could be an useful predictor of abortion risk in reproductive health programmes.
