Parasitic protozoa are classified mainly into four groups. They are: (a) Rhizopoda (Plasmodroma): The organisms of this group move by producing pseudopodia. They multiply by binary fission and form cysts, as in E. histolytica. (b) Mastigophora: The organisms move by means of flagella, binary fission takes place by longitudinal division e.g., Trypanosoma, Leptomonad etc. (c) Sporozoa: They move by amoeboid [...]
In this article we will discuss about: 1. Definition of Protozoology 2. Morphology of Protozoology 3. Life Cycle. Definition of Protozoology: The science of the study of the protozoa is called Protozoology. The term protozoa has been derived from the two Greek words (protos—first, zoon-animal). Protozoans are the first group of organized but simplest animals in the animal kingdom. Modern [...]

In a more restricted sense the name worm, or preferably helminth, is applied to a few phyla of animals, all [...]
