Until 1970, coccidian parasites of dogs were considered to have a direct fecal-oral life cycle like Eimeria in poultry. They were thought to be non-host specific and infect both dogs and cats. Studies conducted in the 1970s revealed that dog coccidia were host-specific and had transport or paratenic hosts that were infected with an encysted stage containing a single organism, the monozoic tissue cyst. There are still considerable confusion and uncertainties concerning the life cycles and pathogenicity of coccidian parasites of dogs. The present paper reviews the history, taxonomy, life cycles, pathogenicity, epidemiology, diagnosis, and treatment of conventional coccidian parasites previously called Isospora spp., currently designated Cystoisospora spp. that infect canines.
直到1970年，犬的球虫寄生虫被认为与家禽中的艾美耳球虫一样具有直接的粪口生活周期。它们被认为是非宿主特异性的，可感染犬和猫。20世纪70年代进行的研究表明，犬球虫是宿主特异性的，具有转运或转续宿主，这些宿主被含有单个生物体（单殖组织囊肿）的包囊阶段感染。关于犬球虫寄生虫的生活周期和致病性，仍然存在相当大的困惑和不确定性。本文综述了以前称为等孢球虫属、目前指定为感染犬科动物的囊等孢球虫属的传统球虫寄生虫的历史、分类学、生活周期、致病性、流行病学、诊断和治疗。
