TL;DR: The results of this study suggest that the N. caninum-infection can be maintained over several generations at a nearly constant prevalence level, apparently without a need for dispersion by an definitive host.

TL;DR: The present study underlines the role farm dogs have in the epidemiology of neosporosis and suggests that the risk a herd has to acquire N. caninum infections is also associated with factors related to the farm location, i.e. factors that are largely out of the control of farmers.

TL;DR: Affinity-purified 38 kDa surface antigen of Neospora caninum tachyzoites was used to develop an enzyme-linked immunosorbent assay (ELISA) to diagnose N.caninum-associated abortion in cattle and serological differences could be demonstrated between herds with epidemic and endemic abortions.

TL;DR: An enzyme-linked immunosorbent assay (ELISA) was established to measure the avidity of bovine IgG directed against p38, a surface antigen of Neospora caninum tachyzoites, suggesting a predominantly vertical transmission of the parasite among the animals of these herds, thus indicating chronic infection of these cattle.

TL;DR: Three antigens of N. caninum with apparent molecular weights of 40, 38, and 19 kDa are located in the outer surface membrane of this parasite stage, and the surface localization of the 38-kDa antigen was obtained by immunoelectron microscopy.
