Parasites


The term parasitism may be defined as a two-species association in which one species, the parasite, lives on or in a second species, the host, for a significant period of its life and obtains nourishment from it. However, there are members of the scientific community who designate all infectious agents of animals as parasites including viruses, protozoa, bacteria and fungi as well as the arthropods, helminths and protozoa. In this forum, we maintain the edict that parasites are those which rely on cats as an essential aspect of their life cycle.
