Cultures grown from patients with bacterial overgrowth syndrome reveal abnormally large numbers of anaerobic bacteria in addition to normal flora. Several protective factors stabilize the number and type of bacteria that colonize the upper GI tract.
An amoeba is a type of unicellular organism usually found in water around decaying vegetation, in wet soil and in animals such as humans. It is relatively advanced, and can extend and retract blob-like arms called pseudopodia, which it can use to grasp food particles and to propel itself through microscopic terrain.
The term amoeboid refers to a cell that resembles an amoeba (plural: amoebae) , that is, one that has no cell wall and moves by flowing over its environment. Many amoebae extend their cells unequally in the form of arms or pseudopodia and are able to surround and enclose their prey.
