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 ...
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 .
Free-living amoebae (or "FLA") [1] are a group of protozoa that are important causes of infectious disease in humans and animals. Naegleria fowleri is often included in the group "free-living amoebae", [2] [3] and this species causes a usually fatal condition traditionally called primary amoebic meningoencephalitis (PAM).
N. fowleri is typically found in warm bodies of fresh water, such as ponds, lakes, rivers and hot springs. It is found in an amoeboid , temporary flagellate stage or microbial cyst in soil, poorly maintained municipal water supplies, water heaters, near warm-water discharges of industrial plants and in poorly chlorinated or unchlorinated ...
The amoeba can 'bore' into the intestinal wall, causing lesions and intestinal symptoms, and it may reach the bloodstream or peritoneal cavity. [8] From there, it can reach vital organs of the human body, usually the liver, but sometimes the lungs, brain, and spleen. [9]
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.
For example, in a recent TED talk, physicist and entrepreneur Riccardo Sabatini demonstrated that a printed version of the entire human genetic code would occupy some 262,000 pages, or 175 large ...
Entamoeba gingivalis is an opportunistic Amoebozoa [citation needed] (reported by some as an effect of disease; not a cause [hence status as a commensal]) [2] [3] [4] and is the first amoeba in humans to be described. It is found in the mouth [5] inside the gingival pocket biofilm near the base of the teeth, and in periodontal pockets. [1 ...
