Difflugia is the largest genus of Arcellinida, one of several groups of Tubulinea within the eukaryote supergroup Amoebozoa. [1] Arcellinida species produce shells or tests from mineral particles or biogenic elements (e.g. diatom frustules) and are thus commonly referred to as testate amoebae or shelled amoebae.
An amoeba of the genus Mayorella (Amoebozoa, Discosea). Amoebozoa is a large and diverse group, but certain features are common to many of its members. The amoebozoan cell is typically divided into a granular central mass, called endoplasm, and a clear outer layer, called ectoplasm.
The heterolobosean pathogen Naegleria fowleri can behave as an amoeba (center) or as a flagellate (right). An amoeboflagellate ( pl. amoeboflagellates ) is any eukaryotic organism capable of behaving as an amoeba and as a flagellate at some point during their life cycle.
Clockwise from top right: Amoeba proteus, Actinophrys sol, Acanthamoeba sp., Nuclearia thermophila., Euglypha acanthophora, neutrophil ingesting bacteria. An amoeba (/ ə ˈ m iː b ə /; less commonly spelled ameba or amœba; pl.: amoebas (less commonly, amebas) or amoebae (amebae) / ə ˈ m iː b i /), [1] often called an amoeboid, is a type of cell or unicellular organism with the ability ...
The protist can exist in two different forms: flagellate and amoeboid. It is the only known species of cutosean amoebas having both forms, [ 8 ] as all other cutoseans are non-flagellated. [ 9 ] As a flagellate, it projects out a single flagellum of about 30 μm long from the basal body and lives as a free swimmer in water. [ 1 ]
Thecamoeba is a genus of Amoebozoa with a tough pellicle simulating a shell.. It includes the species: T. aesculea Kudryavtsev & Hausmann 2009; T. assimilis Lepşi 1960; T. bilizi (Schaeffer 1926)
The Archamoebae are a group of protists originally thought to have evolved before the acquisition of mitochondria by eukaryotes. [1] 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.
[1] [15] For some of these bacteria, replication inside Acanthamoeba has been associated with enhanced growth in macrophages, and increased resistance to some antibiotics. [1] Furthermore, due to the high prevalence of Acanthamoeba in the environment, these amoebae have been proposed to serve as an environmental reservoir for some human pathogens.
