What are the characteristics of flagellates?
Trypanosomes are uniflagellated blood parasites of man and other vertebrates. They occur in variety of forms and all these forms (Fig.
What diseases are caused by flagellates?
Flagellates. Flagellates are characterized by the possession of one or more flagella, which are long, tapering, hair-like appendages that act as organelles of locomotion and feeding (Fig. 2.1 A).
What are the diseases caused by protozoans?
In humans and other mammals, several widespread diseases are caused by flagellates. Perhaps the most widespread is giardiasis caused by the intestinal parasite Giardia lamblia, with symptoms such as diarrhea (water and nutrient loss) and painful abdominal cramps.

What protozoa means?
Protozoan infections are responsible for diseases that affect many different types of organisms, including plants, animals, and some marine life. Many of the most prevalent and deadly human diseases are caused by a protozoan infection, including African Sleeping Sickness, amoebic dysentery, and malaria.
What are the five characteristics of protozoa?
Protozoa (also protozoan, plural protozoans) is an informal term for a group of single-celled eukaryotes, either free-living or parasitic, that feeds on organic matter such as other microorganisms or organic tissues and debris.

How are protozoa useful to us?
Protozoa are single celled organisms. They come in many different shapes and sizes ranging from an Amoeba which can change its shape to Paramecium with its fixed shape and complex structure. They live in a wide variety of moist habitats including fresh water, marine environments and the soil.
What are protozoa useful?
Protozoans play important roles in the fertility of soils. By grazing on soil bacteria, they regulate bacterial populations and maintain them in a state of physiological youth—i.e., in the active growing phase. This enhances the rates at which bacteria decompose deceased organic matter.
