Publisher Summary This chapter focuses on the classification, diversity, and methods of preservation of protozoa. The protozoa are significant components of the biota of diverse ecosystems; they exist in soils from polar regions to hot spring runoffs, in marine, estuary, or fresh water, at all altitudes, in sewage treatment systems, and in droplets ...

, 1987 This chapter contains some comprehensive ideas and principles about the role of protozoa in nature. These considerations are often discussed separately for different types of habitats, such as marine plankton or soils. In many respects the functional roles (niches) of protozoa do not differ fundamentally among different ecosystems and so it seems ...

In ciliates there are examples of cells which have different proliferation potential in the macronucleus. Those species with limited macronuclear proliferation potential require sex to activate the reserve nucleus. In terms of the capital investment theory, some ciliates invested in their spare nucleus without loss of their original potential, while ...

Publisher Summary This chapter deals with those protozoan diseases that occur spontaneously in laboratory mice. This information is organized according to the major organ systems affected and the taxonomic classification of the protozoan. The chapter presents a brief description of each parasite and discusses its structure, life cycle, pathogenesis ...

Publisher Summary The Kingdom Protozoa contains a diverse collection of single-celled eukaryotic organisms that in many ways bridge the gap between the plant and animal worlds. Protozoa may be free living or parasitic, may be capable of photosynthesis, or may be thriving in a microaerophilic environment.
