The amoebae that parasitize the intestinal tracts of humans belong to four genera: Entamoeba, Endolimax, Iodamoeba and Blastocystis. They all belong to phylum Amoebozoa, subphylum Conosa, which contains organisms that move by means of cytoplasmic protrusion called PSEUDOPODIUM. Ref: Manual of Clinical Microbiology; ASM press
