Neospora caninum, Toxoplasma gondii, and Sarcocystis spp. are related Apicomplexan parasites that have 2 hosts in their life cycles. The definitive hosts excrete unsporulated (Neospora caninum, T gondii) or sporulated (Sarcocystis spp.) oocysts in their feces after ingesting tissue cysts from the tissues of ruminant intermediate hosts. These coccidians can cause abortion and neonatal mortality in ruminants. T gondii and Sarcocystis hominis (from cattle) are zoonotic. This article reviews information on the etiology, life cycle, diagnosis, control and prevention of these parasites and the diseases they cause in ruminants.
刚地弓形虫、犬新孢子虫和肉孢子虫属等相关顶复门寄生虫在其生活史中有 2 个宿主。终末宿主在摄入反刍动物中间宿主组织中的包囊后，粪便中排出未孢子化的（犬新孢子虫、刚地弓形虫）或孢子化的（肉孢子虫属）卵囊。这些球虫可引起反刍动物流产和新生动物死亡。刚地弓形虫和牛源的肉孢子虫（来自牛）是人畜共患病寄生虫。本文综述了这些寄生虫的病因学、生活史、诊断、控制和预防以及它们在反刍动物中引起的疾病的相关信息。
