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

Neosporosis in animals--the last five years.

TL;DR: This review is focused on current status of neosporosis in animals based on papers published in the last five years and strategies for control and prevention are discussed.

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.
Journal ArticleDOI
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.

Control options for Neospora caninum infections in cattle — current state of knowledge

TL;DR: It is suggested that concomitant infections with bovine pestivirus increase the risk of abortion significantly and that these infections, for which effective vaccines exist, should therefore be controlled.

TL;DR: Sera from 300 dogs from Ghent and Antwerp were tested for antibodies to Neospora caninum using an indirect fluorescent antibody test, and there was an increase in seropositivity with age.

TL;DR: The specificity of the IB was superior to that of the IFAT in relation to histology/immunohistochemistry, maternal serology and PCR as well as to the results of maternal serological examinations.

Toltrazuril treatment to control diaplacental Neospora caninum transmission in experimentally infected pregnant mice.
TL;DR: In this article, the authors addressed the question whether diaplacental transmission of Neospora caninum can be controlled by metaphylactic chemotherapy using toltrazuril or enrofloxacin.
Occurrence of antibodies to Neospora caninum and Toxoplasma gondii in dairy cattle from the northern region of the Paraná State, Brazil (Ocorrência de anticorpos contra Neospora caninum e Toxoplasma gondii em bovinos leiteiros da região Norte do estado do Paraná)
L. Ogawa,O. Vidotto +1 more
TL;DR: The data suggest that neosporosis is present among dairy cattle in the studied geographic region and the simultaneous detection of serum positive animals to both types of coccidian parasite demonstrates the independent occurrence of these coccidia in dairy cows.
