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

TL;DR: Findings indicate that N. caninum may infect a wider range of hosts than described to date, and that further studies should be performed in order to determine the presence of the infection in different avian species.

TL;DR: Almost all the wild carnivoran mammal species tested are intermediate hosts for N. caninum and are therefore capable of acting as reservoirs of infection for other species and demonstrating the presence of the parasite in particular geographical and environmental locations.

TL;DR: In the absence of widely accepted international guidelines, this paper summarized and discussed the different models and parameters currently in use and identified the main knowledge gaps for the development of non-pregnant and pregnant ruminant models.

TL;DR: It is demonstrated that extension of the observation period after N. caninum infection permits a more accurate study of vertical transmission, the major route of parasite transmission, and mortality rates, and it is proposed that infection at mid-gestation in BALB/c mice and its study during the post-natal period constitutes a valuable experimental model for testing new chemotherapeutic agents and vaccines designed to protect against congenital neosporosis.

TL;DR: Dogs are a definitive host of Neospora caninum, and mice inoculated with canine faecal extracts were monitored for evidence of neosporosis using a variety of morphologic, immunohistologic, serologic, and genetic analyses.
