The absorption of glucose and L-methionine was as much as 52% less in the intestine of broilers inoculated with 2 strains of Eimeria mitis than in the intestine of noninoculated controls. This malabsorption was observed in the region of, and caudad to, the yolk sac diverticulum. Malabsorption was greater in birds given 500,000 sporulated oocysts than in those given 50,000 sporulated oocysts/bird. Depigmentation of the plasma was also considered an indication of malabsorption. Gross lesions were not evident in the intestine of these infected birds, even though histopathologic sections showed the presence of numerous parasites. Body weight was also less in inoculated birds, but PCV and plasma protein concentrations were not affected.
接种两株温和艾美耳球虫的肉鸡肠道对葡萄糖和L-蛋氨酸的吸收比未接种的对照组少52%。这种吸收不良在卵黄囊憩室及其尾侧区域可见。给予每只鸟50万个孢子化卵囊的鸡比给予5万个孢子化卵囊的鸡吸收不良更严重。血浆色素脱失也被认为是吸收不良的一个指标。尽管组织病理学切片显示存在大量寄生虫，但这些受感染鸡的肠道肉眼病变并不明显。接种鸡的体重也较轻，但红细胞压积和血浆蛋白浓度未受影响。
