condition associated with Giardia intestinalis. In
some cases, a variation of a scientific genus name
may be used to refer to a genus of parasites. Here
is an example of this use of a genus name.
Chapter 5 of this text discusses two genera of
parasites, Leishmania and Trypanosoma. In
general, reference to infections with these two
genera is often written as leishmanial infections
and trypanosomal infections.
Along with specific parasite name variations,
variations of parasite category names are
common. An example of this terminology is the
amebas (Chapter 3). When appropriate, reference
to the amebas may be written in several
ways, such as amebic or ameboid.
There are several different parasite classification
systems, ranging from very basic to complex.
The system used in this text delineates three
major groups of clinically significant parasites:
1. Single-celled parasites—Protozoa (Fig. 1-2)
2. Multicellular worms—Metazoa helminths
(Fig. 1-3)
3. Arthropods (insects and their allies)—Animalia
(Fig. 1-4)
