N. fowleri can invade and attack the human nervous system. Although this occurs rarely, such an infection nearly always results in the death of the victim. Naegleria fowleri ( /nəˈɡlɪəriə/; also known as “the brain-eating amoeba”) is a free-living excavate form of protist typically found in warm bodies of fresh water, such as ponds, lakes, rivers, and hot springs. It is also found in soil, near warm water discharges of industrial plants, and minimally chlorinated swimming pools (there is no evidence of this organism living in ocean water) in an amoeboid or temporary flagellate stage. It belongs to a group called the Percolozoa or Heterolobosea. Although not a true amoeba, the organism is often referred to as an amoeba for convenience.
