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.
犬新孢子虫是一种细胞内原生动物寄生虫，于1988年在一只狗身上被发现。从那时起，犬新孢子虫已在多种动物物种中被证实，并且它已被公认为牛流产的一个重要原因。犬新孢子虫感染可通过母牛经胎盘传播给犊牛而在牛群中持续几代。最近，已证明狗可作为犬新孢子虫的终末宿主，因此可能通过排出卵囊而成为其他物种的感染源。狗在将感染传播给牛方面所起作用的进一步证据来自流行病学研究。本文对目前的知识状况进行了综述。
