Amoebae do not form a single taxonomic group; instead, they are found in every major lineage of eukaryotic organisms. Amoeboid cells occur not only among the protozoa, but also in fungi, algae, and animals. [3][4][5][6][7]

List of six examples of Amoeboid Protozoans. Example # 1. Amoeba Proteus-The Proteus Animalcule: Amoeba was discovered by Russel von Rosenhoff in 1755. H.I. Hirschfied (1962) has given a detailed account of the biology of Amoeba. It is found in fresh water. Types of pseudopodia are lobo podia. A contractile vacuole is present for osmoregulation.

2019年10月4日 · An amoeba is a highly motile eukaryotic, unicellular organism. Typically belonging to the kingdom protozoa, it moves in an “amoeboid” fashion. As such, microbiologists often use the term “amoeboid”, to refer to a specific type of movement and amoebae interchangeably.

2025年1月30日 · Amoeba, any of the microscopic unicellular protozoans of the rhizopodan order Amoebida. The well-known type species, Amoeba proteus, is found on decaying bottom vegetation of freshwater streams and ponds. There are numerous parasitic amoebas. Of six species found in the human alimentary tract,

Amoebozoa is a major taxonomic group containing about 2,400 described species of amoeboid protists, [8] often possessing blunt, fingerlike, lobose pseudopods and tubular mitochondrial cristae. [7] [9] In traditional classification schemes, Amoebozoa is usually ranked as a phylum within either the kingdom Protista [10] or the kingdom Protozoa.

Amoeboid protozoans can be described as a group of protozoans, which can be defined by their amoeboid movements. Their body lacks a Periplast. These kinds of protozoans are mostly free-living, found in freshwater, seawater, and on damp soil.

2024年10月28日 · Focusing on four major types—amoeboids, flagellates, ciliates, and sporozoans—this article explores how each employs unique mechanisms to navigate their environments. These distinct forms of locomotion highlight the adaptability and complexity of life at the microscopic level.

2024年10月20日 · Amoeboid movement, characterized by the extension and retraction of pseudopodia, is another strategy employed by protozoa like Amoeba proteus. This type of movement involves the flow of cytoplasm into temporary projections, enabling the …

2025年1月17日 · Amoebae are defined based on pseudopodia type: those with thin, or filose, pseudopods, which may be reinforced by stiff microtubule proteins, are classified in the supergroup Rhizaria (e.g., foraminiferans and radiolarians), whereas those with lobose pseudopods, which are blunt and are not reinforced, are classified in the supergroup Amoebozoa.

1999年6月1日 · This article presents the current knowledge about the antimicrobial and cytolytic polypeptides of amoeboid protozoa, with an emphasis on E. histolytica. The few polypeptides characterized at the molecular level are briefly compared to those of defensive systems of higher organisms, i.e. of vertebrates and arthropods.
