is a non-pathogenic amoeba present in the human intestine (Dobell,
1919). It is about 6-25 in length.
The cysts contain glycogen filled so-called vacuoles that stains brown
with Iodine, and these cysts were therefore called "I-cysts"
before they were known to be the cysts of an amoeba hence the name
"Iodamoeba"(Jahn & Jahn, 1949)
However T.E.M. reveals that the glycogen bodies are not surrounded by a
membrane (Zaman et al, 1998).,
so they cannot e called vesicles. The amoebae contain no
recognisable mitochondria (but see Entamoeba).
