The same Giardia lamblia (intestinalis) cyst as imaged at different instrument settings by confocal microscopy共聚焦显微镜. (A) is the cyst孢子囊 imaged by transmission (differential interference contrast), only. (B) is the cyst wall囊壁 selectively imaged through use of fluorescent-labelled (TRITC) antibody that is cyst wall specific. (C) is the cyst imaged through use of carboxy fluorescein diacetate, a viability stain. (D) is a composite image of (B) and (C). (E) is a composite image of (A), (B), and (C). Bar = 10 microns.
