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 ...
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.
One of the shared features of these organisms is their motility, crucial for nutrient acquisition and avoidance of danger. [7] In the process of evolution, single-celled organisms have developed in a variety of directions, and thus their rich morphology results in a large spectrum of swimming modes.
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.
The list of organisms by chromosome count describes ploidy or numbers of chromosomes in the cells of various plants, animals, protists, and other living organisms.This number, along with the visual appearance of the chromosome, is known as the karyotype, [1] [2] [3] and can be found by looking at the chromosomes through a microscope.
From there, it can reach vital organs of the human body, usually the liver, but sometimes the lungs, brain, and spleen. [9] A common outcome of this invasion of tissues is a liver abscess, which can be fatal if untreated. [8] Ingested red blood cells are sometimes seen in the amoeba cell cytoplasm. [10]
The brain-eating amoeba was blamed for the death in June of an 18-year-old Ohio woman, who became infected after rafting at the U.S. National Whitewater Center in Charlotte, North Carolina.
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 amoebae in possessing flagella . Most have a single nucleus and flagellum, but the giant amoeba Pelomyxa has many of each.
