The first image shows trophozoite morphology, the second shows the flagella in the flagellar stage, and the tried shows the cyst stage and their walls.
This parasite can be identified using microscopic examination of the cerebrospinal fluid.
- Cyst: Exist in the environment
- Trophozoite: the infective stage. Penetrates the nasal tissues of humans or animals
- Flagellate: Revert to this stage when there is no food source available. This phase is not infective
- found in warm freshwater environments (host springs and warm water discharge from industrial or power plants, geothermal well water, poorly maintained pools, and soil)
- Most common in southern lakes in the United States
- Children are most likely to be infected, but not all people who are exposed become infected
- Most cases are fatal, but there is research being done which may lead to drug which could treat this parasite
N. fowleri is found worldwide and is fairly rare.
