提要。在接受检查的48只浣熊中，有32只感染了一种以前没有描述过的艾美耳球虫，在这里被称为原艾美耳球虫。在感染的32只动物中，10只还携带有nuttalli，1只携带等孢子虫。卵囊。
原粘虫椭圆形至卵圆形卵囊大小为2 3.4×18.0(16-2 9×13-2 4)μm，孢子囊大小为12.1×9.3(11.5-15×7-10)μm，每个孢子囊含有一个稍扁平的间质小体。残存的孢子囊由许多散在的颗粒组成，每个颗粒的直径为1∼m。卵囊壁为双层结构。外层粗糙且有凹坑，大小为1.5μm，但珠孔处有1μm厚。
等孢霉(Isospora sp.)直径16.8×13.7(16-18.5×12.5-15.5)μm，单层∼0.5μm厚。孢子囊大小为11.2×9.1(9.5-11.5×8-10)μm，每个孢子囊含有4个细长的子孢子。Nuttalli卵囊大小为17.5×13.6(12-21×11-15)μm，单层光滑，壁厚约0.7μm。孢子囊大小为12.2×7.1(9-13×5.5-11)μm，每个孢子囊有一个细长的深色针状小体，残存的孢子囊由许多细小颗粒组成。
SYNOPSIS. Thirty-two of 48 raccoons examined were infected with a previously undescribed species of Eimeria which is herein named E. procyonis. Of the 32 infected animals, 10 also harbored E. nuttalli and 1 had Isospora sp. oocysts.
The ellipsoid to ovoid oocysts of E. procyonis measured 23.4 × 18.0 (16–29 × 13–24) μm; its sporocysts measured 12.1 × 9.3 (11.5–15 × 7–10) μm, each containing a slightly flattened substiedal body. The sporocyst residuum consisted of numerous scattered granules each ∼1 μm in diameter. The oocyst wall was double-layered. The outer layer appeared rough and pitted, measuring 1.5 μm, except at the micropyle where it was 1 μm thick.
The oocysts of the Isospora sp. measured 16.8 × 13.7 (16–18.5 × 12.5–15.5) μm. The wall consisted of a single layer ∼0.5 μm thick. The sporocysts measured 11.2 × 9.1 (9.5–11.5 × 8–10) μm, and each contained 4 elongate sporozoites. The oocysts of E. nuttalli measured 17.5 × 13.6 (12-21 × 11-15) μm, with a smooth single-layered wall approximately 0.7 μm thick. The sporocysts measured 12.2 × 7.1 (9-13 × 5.5–11) μm. Each sporocyst had a thin, dark, Stieda body and the sporocyst residuum consisted of many fine granules.
