A new name, Isospora ohioensis, is proposed for I. rivolta-like oocysts from dog feces. The name I. rivolta is retained for the cat species. The structure of the oocysts of I. ohioensis is described from a cloned culture of oocysts. Oocysts are 24 by 21 mum, sporocysts 17 by 12 mum, and sporozoites 10 by 3 mum. In cross-infection experiments none of 6 coccidia-free dogs shed oocysts after consuming feline I. rivolota, and none of 4 coccidia-free cat shed oocysts after eating canine I. rivolta.
为来自狗粪便中类似里氏等孢球虫的卵囊提出了一个新名称——俄亥俄等孢球虫。里氏等孢球虫这个名称保留用于猫的种类。从卵囊的克隆培养物中描述了俄亥俄等孢球虫卵囊的结构。卵囊大小为24×21微米，子孢子囊大小为17×12微米，子孢子大小为10×3微米。在交叉感染实验中，6只无球虫的狗在食用猫的里氏等孢球虫后均未排出卵囊，4只无球虫的猫在食用狗的里氏等孢球虫后也均未排出卵囊。
