A Protist Investigation Chapter 15 - Protists Although protists are tiny, the menace they pose to plant and animal health can be huge. For a first look at some pesky protists, take a look at The Bad Bug Book, brought to you by the U.S. Food and Drug Administration. This site is a guide to the many disease-causing organisms and toxins that can be found in food. Of particular interest is the section about parasitic protozoa, such as Giardia and Cryptosporidium. For more on Giardia, Cryptosporidium, and other disease-causing protists, use the search function at the left side of the Centers for Disease Control and Prevention Home Page. To start, enter "protozoan" and take a look at some of the articles that come up. Information about the health problems of our photosynthetic friends and how those problems can be prevented or controlled can be found among the Oklahoma Extension Plant Disease Publications. Red tide is a population explosion of a red-colored protist that can kill fish and shellfish and cause poisoning in humans. For more information about red tide and other marine menaces, visit The Harmful Algae Page. The site includes photos and descriptions of the harmful species and their effects on both humans and the environment, as well as a page that identifies areas where outbreaks are occurring.
