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: Investigation of pampas-deer captured in two different Brazilian environments suggested that the presence of domestic animals, mainly dogs and cattle, may be responsible for the greater occurrence of N. caninum in the Pantanal cervids.

TL;DR: It seems that increased rainfall in a dry environment can compromise the success of gestation in N. caninum-infected cows, and attempts should be made to reduce environment effects during the second trimester of gestation, a period in which the immune response of cows is diminished.

ELISA detection of IgG antibody against a recombinant major surface antigen (Nc-p43) fragment of Neospora caninum in bovine sera
TL;DR: This study shows that Ncp43P could be available as an efficient antigen for the diagnosis of neosporosis in cattle and together with TgSAG1A could be useful for the differential diagnosis of N. caninum and T. gondii infections in other mammals.

Prevalence of antibodies to Neospora caninum within central Queensland beef cattle.
TL;DR: The present study aimed to define the age-specific prevalence of antibodies to N caninum in central Queensland beef herds, and found that antibodies to this parasite are more common in older age groups than in younger age groups.
