amoebo-, amoeb-, amoebi-, amebo-, ameb-, amebi-, -amoeba, -ameba +

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

1. A microscopic organism, an amoeba, found in soil, dust and fresh water (lakes, rivers, hot springs and hot tubs).
2. A free-living ameba found in soil, sewage, and water, several species of which cause acanthamebiasis.
3. A genus of free-living soil amoebae that produces no flagellate stage. Its organisms are pathogens for several infections in humans and have been found in the eye, bone, brain, and respiratory tract.

Acanthamoeba occur in brackish water and sea water; as well as, in heating, venting, and air conditioner units, humidifiers, and dialysis units.

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, acanthamoeba can enter the eye and cause infection there.

A particularly dire infection caused by acanthamoeba called granulomatous amebic encephalitis is characterized by 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 amebic dysentery of humans caused by Entamoeba histolytica which rarely occurs spontaneously in dogs and cats.

A similar disease of reptiles and amphibians is caused by Entamoeba invadens and Entamoeba ranarum.

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.
