Clinical disease and mortalities due to disseminated visceral coccidiosis were identified for the first time in a group of captive juvenile Eurasian cranes (Grus grus) in the UK during 2008. Presumptive diagnosis was made from the finding of granulomatous nodules in the liver, spleen and other organs at gross postmortem examination, and confirmed histologically by the presence of intracellular coccidial stages within lesions. The species of coccidian was determined to be Eimeria reichenowi on the basis of faecal oocyst morphology and sequencing of 18S rDNA by PCR. A further outbreak of clinical disease occurred in the same enclosure in 2009, affecting a new group of juvenile Eurasian cranes and demoiselle cranes (Anthropoides virgo) and indicating the persistence of infective oocysts in the environment. Clinical sampling of birds during both years demonstrated positive results from examination of both faecal samples and peripheral blood smears.
2008 年，在英国的一组圈养幼年欧亚鹤中，首次发现了由内脏球虫病引起的临床疾病和死亡率。根据大体剖检时在肝脏、脾脏和其他器官中发现的肉芽肿性结节，以及病变内存在细胞内球虫阶段的组织学确认，做出了疑似诊断。基于粪便卵囊形态和 PCR 扩增的 18S rDNA 测序，确定该球虫物种为瑞氏艾美耳球虫。2009 年，同一围栏中再次发生临床疾病暴发，影响了一群新的幼年欧亚鹤和蓑羽鹤（Anthropoides virgo），表明环境中仍存在感染性卵囊。在这两年中，对鸟类的临床采样显示粪便样本和外周血涂片检查均呈阳性结果。
