title: "Ghost" forms of Giardia lamblia cysts initially misdiagnosed as Isospora.
abstract: Because of their distinctive morphology the cysts of Giardia lamblia usually are not mistaken for cysts or eggs of other intestinal parasites. At a hospital laboratory in Kentucky a case of giardiasis was encountered in which the initial fecal examination revealed only degenerated cysts of Giardia which were mistaken for the oocysts of Isospora at the one-sporoblast stage.
