对采集于中国青海省海北地区的高原鼢鼠 (Myospalax baileyi Thomas) 的 38 份粪便样本进行了球虫（顶复门：艾美耳球虫科）的检测。 38 个粪便样本中的 17 个（44.7%）被发现含有球虫卵囊，代表 1875 年施奈德艾美耳球虫的四种新种，17 只受感染的鼢鼠中有 4 只（23.5%）同时感染了其中的两种或三种艾美耳球虫。艾美耳球虫 (Eimeria myospalacensis n.) 的孢子卵囊。 sp。卵圆形，9.5-17.0 × 8.0-13.0（平均13.0 × 10.4）μm；存在极性颗粒，不存在卵囊残留；孢子囊呈卵形，4.5-7.5 × 3.0-5.0（平均6.3 × 4.2）μm，具有斯泰达体和残体。艾美耳球虫 (Eimeria fani n.) 卵囊sp。椭圆形至圆柱形，12.5-16.0 × 8.0-11.0（平均 14.6 × 9.9）μm；有极性颗粒，但缺乏珠孔和残留物；孢子被卵圆形，4.5-7.5 × 3.0-5.3（平均 6.7 × 4.4）μm；存在残留物和斯泰达体。贝氏艾美耳球虫 (Eimeria baileyii) 卵囊sp。呈椭圆形，15.0-23.0 × 12.0-18.0（平均18.2 × 13.7）μm；存在极性颗粒，但不存在卵囊残留；孢子被卵圆形，8.0-11.0 × 5.0-7.0（平均9.5 × 5.9）μm，具有斯泰达体和残体。门源艾美耳球虫卵囊sp。卵圆形，12.5-21.0 × 11.0-18.0（平均17.1 × 14.6）μm，具有明显的珠孔，宽约2.5μm；存在极性颗粒但不存在残留物；孢子囊呈卵圆形，8.0-12.0 × 5.0-7.0（平均10.2 × 6.4）μm，具有斯泰达体和残体。
Thirty-eight faecal samples from the Plateau zokor, Myospalax baileyi Thomas, collected in the Haibei Area, Qinghai Province, China, were examined for the presence of coccidia (Apicomplexa: Eimeriidae). Seventeen of 38 faecal samples (44.7%) were found to contain coccidian oöcysts representing four new species of Eimeria Schneider, 1875, and four of 17 (23.5%) infected zokors were concurrently infected with two or three of these eimerian species. The sporulated oöcysts of Eimeria myospalacensis n. sp. are ovoidal, 9.5-17.0 × 8.0-13.0 (mean 13.0 × 10.4) μm; a polar granule is present, oöcyst residuum is absent; sporocysts are ovoidal, 4.5-7.5 × 3.0-5.0 (mean 6.3 × 4.2) μm and have both a Stieda body and residuum. Oöcysts of Eimeria fani n. sp. are ellipsoidal to cylindroidal, 12.5-16.0 × 8.0-11.0 (mean 14.6 × 9.9) μm; a polar granule is present, but micropyle and residuum are lacking; sporocysts are ovoidal, 4.5-7.5 × 3.0-5.3 (mean 6.7 × 4.4) μm; a residuum and a Steida body are present. Oöcysts of Eimeria baileyii n. sp. are ellipsoidal, 15.0-23.0 × 12.0-18.0 (mean 18.2 × 13.7) μm; a polar granule is present but oöcyst residuum is absent; sporocysts are ovoidal, 8.0-11.0 × 5.0-7.0 (mean 9.5 × 5.9) μm and have both a Stieda body and residuum. Oöcysts of Eimeria menyuanensis n. sp. are ovoidal, 12.5-21.0 × 11.0-18.0 (mean 17.1 × 14.6) μm, with a distinct micropyle c.2.5 μm wide; a polar granule is present but a residuum is absent; sporocysts are ovoidal, 8.0-12.0 × 5.0-7.0 (mean 10.2 × 6.4) μm, and have both a Stieda body and residuum.
