[The role of the dog in the epidemiology of neosporosis in cattle].
Neospora caninum is an intracellular protozoan parasite that was discovered in a dog in 1988. Since then, N. caninum has been demonstrated in a variety of animal species and it has been recognized as an important cause of abortion in cattle. An infection with N. caninum can be maintained in cattle herds for several generations by transplacental transmission from cow to calf. Recently, it was demonstrated that dogs can act as definitive hosts of N. caninum and therefore may be a source of infection for other species by shedding oocysts. Further evidence of a role of the dog in spreading the infection to cattle has been derived from epidemiological studies. The present state of knowledge is reviewed in this paper.
