2002年，在北海道冬季饲养站附近的一个设施中圈养的年轻日本鹤出现了播散性内脏球虫病（DVC）的症状。筛查结果显示，野生鹤的粪便中存在格氏艾美耳球虫和赖氏艾美耳球虫的卵囊，这是北海道野生鹤首次感染这种病毒的记录。球虫卵囊分布在整个栖息地区域，但尚未发生严重影响。鉴于冬季饲养站鹤的密度较高以及日本繁殖栖息地的减少，艾美尔球虫病对鹤自然种群造成的潜在危险应成为该物种野生动物管理实践中的一个重要关注点。
In 2002, young Japanese Cranes Grus japonensis held captive in a facility located next to the winter feeding station in Hokkaido showed symptoms of Disseminated Visceral Coccidiosis (DVC). Screening revealed the presence of oocysts of the coccidia Eimeria gruis and Eimeria reichenowi in the feces of wild cranes, the first record of this infection in wild cranes in Hokkaido. Coccidian oocysts were distributed throughout the entire habitat area, though no serious effects have yet occurred. Given the high density of cranes at winter feeding stations and the decrease of the breeding habitat in Japan, the potential danger posed to the natural crane population by eimerian coccidiosis should be an important concern in the wildlife management practices for this species.
