is a globally distributed abortifacient protozoan of cattle. Experimental infections with in cattle have provided valuable information on host-parasite interaction and immunopathogenesis. Experimental infection of pregnant cows has been reported in about 20 articles, with most studies using cultured parasite tachyzoites as the inoculum. Only three experimental studies have been conducted in pregnant cows using the parasite's oocysts which are shed by dogs, in large part because transmission experiments using oocysts take more time and are more complex and expensive than experiments using tachyzoites. In this minireview, we discuss differences between tachyzoites and oocysts as inocula for experimental infection of pregnant cows, as well as the route animals are inoculated.
是一种在全球范围内分布的牛堕胎原虫。用其对牛进行实验性感染，为宿主 - 寄生虫相互作用和免疫发病机制提供了有价值的信息。约20篇文章报道了对怀孕母牛的实验性感染，大多数研究使用培养的寄生虫速殖子作为接种物。仅有三项针对怀孕母牛的实验研究使用了由狗排出的寄生虫卵囊，这在很大程度上是因为使用卵囊进行传播实验比使用速殖子的实验耗时更长、更复杂且成本更高。在本综述中，我们讨论了速殖子和卵囊作为怀孕母牛实验性感染接种物的差异，以及动物的接种途径。
