Naegleria fowleri is a brain-eating amoeba that causes meningioencephalitis after exposure to which environment?

Explanation:
Naegleria fowleri causes disease when water containing the amoeba is forced up the nose, allowing it to reach the brain via the olfactory nerves. This makes exposure to warm freshwater (lakes, rivers, hot springs) the classic risk factor. The organism is not typically contracted from saltwater, soil, or boiled water—boiling would kill it. So freshwater exposure best explains how this infection occurs.
