Eimeria nuttalli oocysts were found in 58% (21/36) and E. procyonis oocysts in 25% (9/36) of raccoons Procyon lotor in Illinois, and sporocysts of Sarcocystis sp. in 17% (2/12) of other raccoons in Illinois. The oocysts of E. nuttalli were ellipsoidal to ovoid, 15-21 X 12-17 micrometer, with a one-layered, smooth, colorless wall. The oocysts of E. procyonis were 22-28 X 18-22 micrometer, with a rough, striated, brownish, two-layered wall. The sporulated sporocysts of Sarcocystis sp. were 11-13 X 8-10 micrometer. Attempts to infect baby pigs by feeding them sporocysts of Sarcocystis sp. from the reaction failed.
在伊利诺伊州的食蟹浣熊（Procyon lotor）中，58%（21/36）的浣熊体内发现了纳氏艾美耳球虫（Eimeria nuttalli）卵囊，25%（9/36）的浣熊体内发现了犬小熊猫艾美耳球虫（E. procyonis）卵囊；在伊利诺伊州的其他浣熊中，17%（2/12）的浣熊体内发现了肉孢子虫属（Sarcocystis sp.）的子孢子。纳氏艾美耳球虫的卵囊呈椭圆形至卵形，大小为15 - 21×12 - 17微米，壁为单层、光滑、无色。犬小熊猫艾美耳球虫的卵囊大小为22 - 28×18 - 22微米，壁粗糙、有条纹、呈褐色、为双层。肉孢子虫属的孢子化子孢子大小为11 - 13×8 - 10微米。通过给仔猪喂食来自有反应的浣熊的肉孢子虫属子孢子来尝试感染仔猪，但未成功。
