The Archamoebae are a group of protists originally thought to have evolved before the acquisition of mitochondria by eukaryotes. They include genera that are internal parasites or commensals of animals (Entamoeba and Endolimax). A few species are human pathogens, causing diseases such as amoebic dysentery.

Aug 1, 2017 · General Characteristics. The Archamoebae is a group of amoebae, amoeboid flagellates, and amoeboflagellates (i.e., organisms with both flagellates and amoebae in their life cycle), with distinctive hyaline cytoplasm and bulging pseudopodia (Fig. 1 ).

Pelomyxa is a genus of giant flagellar amoebae, usually 500–800 μm but occasionally up to 5 mm in length, found in anaerobic or microaerobic bottom sediments of stagnant freshwater ponds or slow-moving streams. [1] The genus was created by R. Greeff, in 1874, with Pelomyxa palustris as its type species. [2]

May 1, 2013 · The archamoebae is comprised of mostly free-living flagellated pelobionts (mastigamoebids and pelomyxids) and endobiotic aflagellate entamoebae. The best known is Entamoeba histolytica, that causes amoebic dysentery of humans.
Jan 9, 2013 · R. libera possesses an ultrastructure unique within archamoebae: a rhizostyle formed from a modified microtubular cone and a flagellum with vanes. While many nominal species of pelobionts are extremely hard to distinguish by light microscopy, transient pseudopodial characters are worthy of further investigation as taxonomic markers.
