The two main groups of parasites are the microparasites and the macroparasites. Protozoa are microparasites as they multiply within the host. Macroparasites on the other hand, establish themselves in or on the host but produce eggs or larvae which are dispersed to the environment. Macroparasites include helminths and arthropods. The number of macroparasites in the body reflects the number which invaded the animal.
  
Parasitology is the study of parasites, their hosts and the relationship between the two. Parasitology, as opposed to microbiology is generally concerned with eukaryote organisms. The parasitic mode of life is the most common on the planet and the number of parasitic species greatly exceeds the number of free-living hosts.

Parasites

Parasitism is the relationship between two organisms where one is living at the expense of the other. Parasites are highly specialised, have nutritional dependence on the host and can avoid an immunological attack. They have evolved to integrate their life cycle with that of their host species. The two main groups of parasites are the microparasites and the macroparasites. Protozoa are microparasites as they multiply within the host. Macroparasites on the other hand, establish themselves in or on the host but produce eggs or larvae which are dispersed to the environment. Macroparasites include helminths and arthropods. The number of macroparasites in the body reflects the number which invaded the animal.
