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.

A nationwide survey on seroprevalence of Neospora caninum infection in beef cattle in Uruguay.
TL;DR: Results show that N. caninum infection is common among beef herds across Uruguay, and since the beef industry is one of the key industries in Uruguay, the economic effect and risk factors of N.Caninum infections should be further evaluated in the near future.

TL;DR: Seropositive cattle were detected in all surveyed districts despite the evidence of confirmed case reports of bovine neosporosis, showing that N. caninum is widely distributed throughout Japan and strategies are needed to reduce the economic impact on the Japanese dairy industry.
