Written by Author of Course: This class is intended for the environmental technician but has been adapted from a clinical course. You may find some of the information more detailed than you thought you needed. But lots of background information is always a good thing. This course will introduce you to the most common parasitic group, the Protozoan. This group includes the amoeba, flagellates, ciliates and coccidia. This course will focus on the cyst or environmental form of these organisms. The trophozoite form is the motile stage that lives in the body. And they must be stained with a specific stain to assure identification. Because of that staining procedure, trophozoite identification is another course all by itself. The presented information is applicable for environmental samples and human specimens alike. I do recommend that you have a reference text in your laboratory. There are several good ones available. My personal favorite is Atlas of Human Parasitology, by Lawrence Ash and Thomas Orihel. This one has of lots of color photos and extensive section of artifacts. Another good one is Procedure Manual for the Diagnosis of Intestinal Parasites, by Donald L. Price. I like this one because the procedures are explained well and there are some excellent charts for the protozoan.

Basic thru Intermediate

Part 2 is a continuation of Part 1 in that it covers the next set of parasitic organisms. The first sections of part 2 are a review. Read over again, making sure that not only do you remember the information but also that you are using it. As in part 1 I have included lifecycles. They will not be shown for every organism since many are identical. They are intended to give you an overview of how these organisms move through the environment and into the human body.
