Iodine stain. Left, an Entamoeba coli trophozoite. Right, this artefact is morphologically like a trophozoite, but the inside “nucleus” is actually superimposed fecal debris.    

   

Blastocystis hominis appear as spherical to oval cyst-like structures. They vary widely in size (5 to 30 µm; usual range 8 to 10 µm), and typically consist of a central body, or ...

Eggs of Fasciola hepatica are broadly ellipsoidal, operculated and measure 130-150 µm long by 60-90 µm wide. The eggs are unembryonated when passed in feces. The eggs of F. hepatica ...

  This object may be mistaken for thin shelled hookworm eggs or decorticated Ascaris eggs. The irregular contour of the outer membrane and the general appearance should suggest ...

  Capillaria philippinensis eggs are 35 to 45 µm in length by 20-25 µm in width. They have two inconspicuous polar prominences and a striated shell. Eggs are unembryonated when ...

Careful study of the inner mass reveals its lack of typical features of an oncosphere normally seen in Taenia eggs (embryonic hooklets, etc.). Absence of the radial striation is ...
