Infection by free-living soil amebae of the genus Acanthamoeba: Acanthamebiasis may result in a necrotizing dermal or tissue invasion, or a fulminating and usually fatal primary amebic meningoencephalitis.

A microscopic organism, an amoeba of the genus Amoebae, found in soil, dust and fresh water: The free-living acanthamoeba can be found in sewage, brackish water, sea water, in heating, venting, and in air conditioner units, humidifiers, and in dialysis units.

There are two specific species, which are the trophozoite, metabolically active, and a cyst, which is dormant and stress-resistant. These species can cause the infection termed acanthamebiasis.

The acanthamoeba does not produce a flagellate stage. Its organisms are pathogens for several infections in humans and have been found in the eye, bone, brain, and respiratory tract.

They can enter the skin through a cut, wound, or through the nostrils and, once inside the body, can travel to the lungs and through the bloodstream to other parts of the body, especially to the central nervous system (the brain and spinal cord). Through improper storage, handling, and disinfection of contact lenses, acanthamoebae can enter the eye and cause an infection there.

A particularly dire infection caused by acanthamoebae, called granulomatous amebic encephalitis, is characterized by a headache, stiff neck, nausea, vomiting, confusion, loss of balance, seizures, and coma that can progress over several weeks and end in death.

Pertaining to, referring to, or of the nature of an ameba.

An acute inflammation of the intestines which is usually caused by ingesting food or water contaminated with feces containing microscopic, single-celled, parasitic organisms; resulting in severe diarrhea: "The team of doctors developed a simple mechanism for the purification of water in an effort to diminsh and overcome the outbreak of amebic dysentery in the rural areas of the country."

Extensive destruction of the skin surrounding a draining wound, following removal of an amebic abscess of the liver.

A world-wide disease of goldfish; cause not definitely known; characterized by white nodules on the skin, visceral granulomata and ascites.

A diffuse inflammation of the liver secondary to amebic colitis.

Destructive to amebae.

1. A chemical agent used to kill amoebas.
2. A drug that kills amoebas: an antiameba drug. 3. Anything which kills, or is lethal, to amebae.

Shaped like, or resembling an ameba.

1. The ability to move by cytoplasmic streaming and the formation of pseudopodia, as in ameba.
2. Infection by amebas; amebiasis.

1. An ameboid white blood cell found primarily in invertebrates.
2. A cell that can wander freely in animal tissues.

Amebocytes are found, for example, in the walls of sponges and in the blood and body fluids of mammals.

They have the general appearance of Amoeba, particularly in exhibiting ameboid movement.

1. Having ameboid and flagellated stages (long thin cellular appendages) in the life cycle.
2. An ameba that has a flagellated stage in its life cycle.

1. A tumorlike mass of the colon caused by a chronic inflammatory reaction to intestinal amebiasis (infection with amebas).
2. A nodular, tumorlike focus of proliferative inflammation sometimes developing in chronic amebiasis; especially, in the wall of the colon.

A term applied to the excysted young amebas of Entamoeba species that emerge from the cyst in the human, or vertebrate gut, and their immediate progeny, usually totaling eight, prior to their localization in the large intestine.
