Feces from western barred bandicoots, Perameles bougainville, examined during routine monitoring of captive breeding colonies and wild populations were frequently found to contain oocysts. Fecal oocysts from 1 individual housed at Kanyana Wildlife Rehabilitation Centre were allowed to sporulate in 2% potassium dichromate (K2Cr2O7) at room temperature. Sporulated oocysts are subspheroidal 18.8 X 17.9 (16.9-21.0 x 16.0-19.9) microm, with length/width (L/W) ratio of 1.05 (1.00-1.15), lack a micropyle and oocyst residuum, but they usually have a polar granule within a smooth trilaminate oocyst wall 1.0 (0.7-1.3) microm thick. Sporocysts are ovoid, 9.1 x 7.0 (8.1-10.8 x 6.1-8.6) microm, with L/W ratio of 1.32 (1.04-1.51), have a Stieda body, sporocyst residuum, and 2 comma-shaped sporozoites, each containing 2 spheroidal refractile bodies. Sporulation takes 2-5 days at room temperature. This is the first formal description of an Eimeria species parasitic in the order Peramelemorphia.
在对圈养繁殖群体和野生种群进行常规监测期间，对西部斑纹袋狸（Perameles bougainville）的粪便进行检查时，经常发现其中含有卵囊。将一只饲养在卡尼亚纳野生动物康复中心的个体的粪便卵囊置于室温下的2%重铬酸钾（K2Cr2O7）中使其孢子化。孢子化的卵囊呈近球形，大小为18.8×17.9（16.9 - 21.0×16.0 - 19.9）微米，长宽比为1.05（1.00 - 1.15），没有微孔和卵囊残余物，但在厚度为1.0（0.7 - 1.3）微米的光滑三层卵囊壁内通常有一个极粒。孢子囊呈卵形，9.1×7.0（8.1 - 10.8×6.1 - 8.6）微米，长宽比为1.32（1.04 - 1.51），有一个斯氏体、孢子囊残余物和2个逗号形子孢子，每个子孢子含有2个球形折光体。在室温下孢子化需要2 - 5天。这是对寄生于袋狸目动物的艾美耳属物种的首次正式描述。
