由艾美耳球虫属引起的播散性内脏球虫病（DVC）首先在Patuxent野生动物研究中心被认为是圈养沙丘鹤（Grus canadensis）和高鸣鹤（G americana）的疾病实体。由于该中心生产的起重机被重新引入野外以增加野生种群，因此开始了涉及实验诱导和自然感染的研究，以确定DVC在野生Gruidae中的潜在或实际发生。9只沙丘鹤口服野生来源的艾美耳球虫卵囊后出现DVC特征性病变。在6只鸡中发现肠外肉芽肿伴发育中的肉芽肿。在美国中西部、阿拉斯加和萨斯喀彻温省的野生沙丘鹤中也观察到类似的病变。这些研究揭示了丹顶鹤DVC的地理分布广、发生频率高。
Disseminated visceral coccidiosis (DVC) caused by Eimeria spp was first recognized as a disease entity in captive sandhill cranes (Grus canadensis) and whooping cranes (G americana) at the Patuxent Wildlife Research Center. Because cranes produced at the Center are reintroduced to the wild to augment wild populations, studies involving both experimentally induced and natural infections were initiated to determine the potential or actual occurrence of DVC in wild Gruidae. Nine sandhill cranes dosed orally with eimerian oocysts of wild origin developed lesions characteristic of DVC. Extraintestinal granulomas associated with developing schizonts were found in 6 birds. Similar lesions were observed in wild sandhill cranes throughout parts of midwestern United States, Alaska, and Saskatchewan. These studies revealed the wide geographic distribution and the high frequency of occurrence of DVC in wild cranes.
