Archamoebae are a diverse group of amoebae. Many have flagella for motility, while others do not. They grow in the absence of oxygen, though some can tolerate small amounts. Most described species of Archamoebae either lack mitochondria or are described to have reduced mitosomes.
The group Archamoebae was proposed by Thomas Cavalier-Smith in 1998 as part of the Archezoa, a newly-proposed group to include eukaryotes that had diverged before acquisition of mitochondria and other common eukaryotic cell features. Early molecular trees based on rRNA supported this position, placing several Archamoebae genera as separate groups t...

Aug 1, 2017 · 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 ). They comprise three lineages that have collectively been referred to as pelobionts: mastigamoebids, pelomyxids, and ...
Archamoebae adalah sekelompok Amoebozoa [1] dibedakan oleh tidak adanya mitokondria. [2] Mereka termasuk genera yang merupakan parasit atau komensal internal hewan ( Entamoeba dan Endolimax ). Beberapa spesies merupakan patogen pada manusia, menyebabkan penyakit seperti disentri ameba. Genera lain dari archamoebae hidup di habitat air tawar ...

Amoebozoa is a major taxonomic group containing about 2,400 described species of amoeboid protists, [7] often possessing blunt, fingerlike, lobose pseudopods and tubular mitochondrial cristae. [6] [8] In traditional classification schemes, Amoebozoa is usually ranked as a phylum within either the kingdom Protista [9] or the kingdom Protozoa.
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. The other genera of archamoebae live in freshwater habitats and are unusual among ...
