在4.5年的时间里，从加利福尼亚的奶牛场接收的95个流产的牛胎儿有局灶性脑炎的组织学病变。其中88例胎儿的大脑和1例胎儿的心脏中检测到与犬新孢子虫抗血清反应的原生动物。1例胎儿血管内皮可见裂裂性肌囊虫。结论是，一种类似新孢子虫的囊肿形成球虫可能是加利福尼亚奶牛流产的主要原因。
Ninety-five aborted bovine fetuses received from California dairies over a 4.5-year period had histologic lesions of focal encephalitis. Protozoa that reacted with Neospora caninum antiserum were detected in the brain of 88 of these fetuses and in the heart of 1 fetus. Sarcocystis spp schizonts were seen in the vascular endothelium of 1 fetus. It was concluded that a Neospora-like cyst-forming coccidian may be a major cause of abortion in California dairy cattle.
