Amoeba

(ă-mē'bă),
A genus of naked, lobose, pseudopod-forming protozoa of the class Sarcodina (or Rhizopoda), which are abundant soil-dwellers, especially in rich organic debris, and are also commonly found as parasites. The typical amebic parasites of humans are now placed in the genera Entamoeba, Endolimax, and Iodamoeba.

Amoeba

(1) A genus of amoebas of the order Amoebida.
(2) An imprecise name for several types of free-living unicellular phagocytic organisms; the pathogenic amoebas have been reclassified as Entamoeba spp, Endolimax spp, and others
Giant forms (eg. Amoeba proteus may be up to 2 mm long and crawl over surfaces by protruding pseudopods). Amoebae exhibit great plasticity of form and conspicuous cytoplasmic streaming.

amoeba

A single-celled microscopic organism of indefinite shape commonly found in water, damp soil and as parasites of other animals. Some amoebae, such as Entamoeba histolytica and Acanthamoeba castellani cause disease in man, respectively AMOEBIC DYSENTERY and acanthamoebic keratitis.

Amoeba

a genus of unicellular PROTOZOANS in the class Rhizopoda. Amoebae are characterized by their changing shape brought about by the projection of PSEUDOPODIA which have a locomotory function. Amoeba is often wrongly quoted as an example of a primitive organism, low on the evolutionary scale. However, as in many PROTISTA, functions that are carried out by organ systems in so-called ‘higher’ forms are here carried out within a single cell, therefore they cannot be considered ‘primitive’; they are highly evolved over millions of years, albeit on a different scale from higher organisms.

Amoeba

A type of protozoa (one-celled animal) that can move or change its shape by extending projections of its cytoplasm.

Patient discussion about Amoeba

Q. is an Amoeba dangerous?? and how can i get rid of it? my son is in Peru, he called and told me he got an Amoeba..i have no idea if it's dangerous or not, and how to get rid of it. and what kinds of food he needs to avoid.I'll appreciate help!

A. oooo...an Amoeba is a nasty one...but not so dangerous! it's a one celled parasite which gets into your body if you eat in restaurants that the cook doesn't wash hands after going to the bathroom..it multiplies in your intestine and makes you diarrhea like hell. but if you'll treat it right it will go away as nothing happened. if you don't it can give you liver cyst. and that's not good. he should see a Dr.
