1982年10月至1983年1月和1983年10月至1984年1月在新墨西哥州中部采集了212只沙丘鹤（Grus canadensis）的粪便，以确定球虫卵囊的流行。用光镜和透射电镜检查了64只鹤内脏的145个肉芽肿结节和58只鸟的肺、小肠和大肠样品，以确定是否存在肠内或肠外球虫病。在212份粪便标本中，160份（75%）检出艾美耳球虫卵囊，其中包括艾美耳球虫。gruis感染139例（66%），E. reichenowi在118（56%）的样品。鲍氏艾美球虫，新种在两个（约1%）粪便样本中发现。卵囊大小为19-27 × 14-19（23.6 × 17.1）μm，孢子囊大小为10-14 × 7-11（12.3 × 9.3）μm。卵囊外壁粗糙，有大量凹坑，孢子囊残留，Stieda和substieda小体，以及多个极体。大小不等的极体总是聚集在孢子化卵囊的顶端。在1只（0.5%）起重机中发现一种Adelina sp.。球虫的发育阶段被发现在上皮和固有层的小肠和大肠。在口腔粘膜、食管、心脏、降主动脉、肝脏、小肠、肠系膜和腹膜壁层发现播散性肉芽肿结节。光镜和电镜观察到一些结节中有类似球虫无性和有性阶段的独特细胞类型。
The feces of 212 sandhill cranes (Grus canadensis) collected in central New Mexico from October 1982 to January 1983 and from October 1983 to January 1984 were examined to determine the prevalence of coccidial oocysts. One hundred forty-five granulomatous nodules from the viscera of 64 cranes and samples of lung, small intestine, and large intestine from 58 birds were examined by light and transmission electron microscopy for the presence of intestinal or extraintestinal coccidiosis. Of the 212 fecal samples, 160 (75%) were positive for oocysts of Eimeria, including E. gruis in 139 (66%) and E. reichenowi in 118 (56%) of the samples. Eimeria bosquei sp. n. was found in two (∼1%) of the fecal samples. Subspheroid to ovoid oocysts of this new species are 19–27 × 14–19 (23.6 × 17.1) μm with ovoid sporocysts 10–14 × 7–11 (12.3 × 9.3) μm. A rough, heavily pitted outer oocyst wall, sporocyst residuum, Stieda and substieda bodies, and multiple polar bodies are present. The polar bodies, of varying sizes, always aggregate at the apex of the sporulated oocyst. An Adelina sp. was found in one (0.5%) crane. Coccidian developmental stages were found in the epithelium and lamina propria of the small and large intestine. Disseminated granulomatous nodules were found in the oral mucosa, esophagus, heart, descending aorta, liver, small intestine, mesenteries, and parietal peritoneum. Unique cell types resembling coccidian asexual and sexual stages were observed by light and electron microscopy in some of the nodules.
