Most protozoa are free-living and have little or no impact on human health. They are found throughout the environment, particularly in soil and water. However, there are four free-living amoeba that have been associated with serious human infections. This course seeks to identify these amoeba and discuss their life cycles, methods of infection, and the symptoms that occur, as well as determine preventive measures that may be available.
