They possess a cellular membrane and, in contrast to bacteria, a nucleus. Many protozoa have different proliferative stages and undergo substantial changes during their life cycle. As a consequence of their size, which ranges from 10 μm to greater than 50 μm, they can very often easily be found in various tissues (eg, stool, other body fluids). Protozoa are widely distributed throughout the world.
