Biopsy specimens of intestinal mucosa from two patients with malabsorption syndrome were examined with routine light and electron microscopy. Both showed intact intestinal mucosa, but by electron microscopy, the presence of Giardia lamblia in the intervillar spaces was identified. Electron microscopy is useful for the identification of this parasite, since the stool examinations in up to 50% may be negative. The parasites appear in light microscopy as cellular debris and can be easily overlooked, while by electron microscopy the typical morphologic features of the parasite are diagnostic.
对两名吸收不良综合征患者的肠黏膜活检标本进行了常规光学显微镜和电子显微镜检查。两人的肠黏膜均完整，但电子显微镜检查发现绒毛间隙存在蓝氏贾第鞭毛虫。电子显微镜有助于识别这种寄生虫，因为高达50%的粪便检查可能为阴性。在光学显微镜下，这些寄生虫表现为细胞碎片，很容易被忽视，而通过电子显微镜，寄生虫典型的形态特征具有诊断价值。
