Coprological examination of 15 Indian peacocks, Pavo cristatus, revealed the presence of a coccidium species of the genus Eimeria, which apparently represents a previously undescribed species. Sporulation is exogenous and fully developed oocysts of Eimeria pavoaegyptica sp. nov. are ellipsoidal, with a dimension of 15 (13-16) × 12 (10-12.9) microm and with a shape index of 1.25 (1-1.3). The sporulated oocysts have no micropyle but enclose one large rectangular-shaped polar granule and an oocyst residuum. The oocysts have a distinct two-layered wall, which is ~approximately1.7 microm thick. The outer layer has a smooth texture; it fills ~¾ of the total thickness and appears bicolored. The sporocysts are boat-shaped, of about 10 (9-11) × 4 (4-4.7) microm; their average shape-index is 2.5 microm with a small pointed Stieda body and a smooth, thin single-layered wall. No substieda body is detected. The sporocysts contain numerous, nearly uniform granular residua. The sporozoites are banana-shaped, 6 × 3 microm and each has two different-sized refractile bodies.
对 15 只印度孔雀（Pavo cristatus）的粪便检查显示，存在一种艾美尔球虫属（Eimeria）的球虫，显然代表了一种以前未描述过的物种。孢子形成是外生性的，完全发育的艾美尔球虫 nov. 种（Eimeria pavoaegyptica sp. nov.）的卵囊呈椭圆形，大小为 15（13-16）×12（10-12.9）微米，形状指数为 1.25（1-1.3）。孢子化的卵囊没有卵盖，但包含一个大的长方形极粒和一个卵囊残余物。卵囊具有明显的双层壁，厚度约为 1.7 微米。外层具有光滑的纹理；它填充了总厚度的约 ¾，并呈现双色。孢子囊呈船形，长约 10（9-11）×4（4-4.7）微米；其平均形状指数为 2.5 微米，具有一个小的尖端斯氏小体和一个光滑、薄的单层壁。未检测到副斯氏小体。孢子囊内含有大量几乎均匀的颗粒残余物。孢子虫呈香蕉形，6×3 微米，每个都有两个不同大小的折光体。
