A brain-eating amoeba enters through the nose

Naegleria fowleri is an amoeba responsible for a very serious disease called primary amoebic meningoencephalitis. It enters through the nose during swimming in fresh water, then migrates to the brain to destroy the cerebral parenchyma. This condition particularly affects young healthy subjects and shows a minimal survival rate, with only 11 survivors out of 310 cases recorded worldwide in 2014.
