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 ...
Echinamoeba thermarum is an extremely thermophilic amoeba species discovered in various hot springs worldwide. It is notable for its ability to thrive at high temperatures, with an optimal growth temperature of 50°C (122°F).
Amoeba is a genus of single-celled amoeboids in the family Amoebidae. [2] The type species of the genus is Amoeba proteus , a common freshwater organism, widely studied in classrooms and laboratories.
Naegleria fowleri, also known as the brain-eating amoeba, is a species of the genus Naegleria. It belongs to the phylum Percolozoa and is classified as an amoeboflagellate excavate , [ 1 ] an organism capable of behaving as both an amoeba and a flagellate .
Arcellinid testate amoebae or Arcellinida, [1] Arcellacean [2] or lobose testate amoebae [3] are single-celled protists partially enclosed in a simple test (shell).. Arcellinid testate amoebae are commonly found in soils, leaf litter, peat bogs and near/in fresh water. [1]
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.
A map of case reports through 2021 shows exposures in 20 states, with most reports coming from the South. The amoeba thrives in warm freshwater, including lakes, rivers, and, occasionally ...
The locomotion of Amoeba proteus exhibits chaotic dynamics described by a low-dimensional chaotic attractor with a correlation dimension around 3-4, indicating that the seemingly random movement arises from deterministic cooperative interactions among a small number of processes like sol-gel transformations, cytoplasmic streaming, and calcium-mediated reactions.
