Between 1986 and 1995, 548 fecal samples were collected from 41 species of bats (Molossidae, Mormoopidae, Phyllostomidae, Thyropteridae, and Vespertilionidae) from New Mexico, California, Baja California Sur (Mexico), and Bolivia. Of these, the feces of 28 (5%) bats, including Antrozous pallidus, Myotis ciliolabrum, Myotis lucifugus, and Myotis yumanensis (Vespertilionidae), contained oocysts representing at least 3 species of Eimeria. A new species of eimerian from M. lucifugus (3/27, 11%) and M. yumanensis (8/70, 11%) is described. Sporulated oocysts are ellipsoidal, 22.3 x 14.8 (18-25 x 13-16) microns with micropyle (approximately 2 microns) and polar granules (1-4), but an oocyst residuum is absent. The oocyst wall is slightly rough exteriorly and has 2 layers (total < or = 1 micron thick). Football-shaped sporocysts are 8.1 x 6.6 (8-11 x 5-7) microns, each with a Stieda body and granular sporocyst residuum present. A new eimerian from M. yumanensis (4/70, 6%) and M. ciliolabrum (1/12, 8%) also is described. Sporulated oocysts are spheroidal to subspheroidal, 15.0 x 14.1 (14-16 x 14-16) microns, with micropyle and oocyst residuum absent; a polar granule is present. The wall is smooth and has 2 layers (total < 1 micron thick). Sporocysts are football-shaped, 7.1 x 5.9 (6-9 x 5-7) microns, each with a Stieda body and sporocyst residuum. The sporulated oocysts of a third morphotype, found in A. pallidus (12/85, 14%), were indistinguishable from those of Eimeria arizonensis, a species typically found in murid rodents. The currently recognized species of bat Eimeria are listed, and a dichotomous key is provided.
1986年至1995年间，从新墨西哥州、加利福尼亚州、南下加利福尼亚州（墨西哥）和玻利维亚的41种蝙蝠（犬吻蝠科、叶口蝠科、叶鼻蝠科、膜翅蝠科和蝙蝠科）中收集了548份粪便样本。其中，28只（5%）蝙蝠的粪便，包括苍白洞蝠、纤毛鼠耳蝠、棕蝠和尤马鼠耳蝠（蝙蝠科），含有代表至少3种艾美耳球虫的卵囊。描述了一种来自棕蝠（3/27，11%）和尤马鼠耳蝠（8/70，11%）的新艾美耳球虫种类。孢子化卵囊呈椭圆形，22.3×14.8（18 - 25×13 - 16）微米，有微孔（约2微米）和极粒（1 - 4个），但无卵囊残体。卵囊壁外部略粗糙，有两层（总厚度≤1微米）。足球形孢子囊为8.1×6.6（8 - 11×5 - 7）微米，每个都有斯氏体和颗粒状孢子囊残体。还描述了一种来自尤马鼠耳蝠（4/70，6%）和纤毛鼠耳蝠（1/12，8%）的新艾美耳球虫种类。孢子化卵囊呈球形至亚球形，15.0×14.1（14 - 16×14 - 16）微米，无微孔和卵囊残体；有一个极粒。壁光滑，有两层（总厚度<1微米）。孢子囊为足球形，7.1×5.9（6 - 9×5 - 7）微米，每个都有斯氏体和孢子囊残体。在苍白洞蝠（12/85，14%）中发现的第三种形态类型的孢子化卵囊与亚利桑那艾美耳球虫（一种通常在鼠科啮齿动物中发现的物种）的孢子化卵囊无法区分。列出了目前已确认的蝙蝠艾美耳球虫种类，并提供了一个双歧检索表。
