一名由多食棘阿米巴引起的角膜溃疡患者成功地接受了穿透性角膜移植治疗。病理标本显示完整的阿米巴周围没有炎性浸润物，而坏死体周围有强烈的细胞反应。间接免疫化学研究显示滋养体染色较深，但囊型在囊壁上显示抗原部位。
A patient with a corneal ulcer caused by Acanthamoeba polyphaga has been successfully treated with a penetrating keratoplasty. The pathologic specimen showed no inflammatory infiltrate surrounding the intact amoeba, whereas necrotic organisms were surrounded by an intense cellular reaction. Indirect immunochemical studies showed that the trophozoite stained profusely, but the cyst form exhibited the antigenic site on the cyst wall.
