Naegleria fowleri
(parasite)

Naegleria fowleri is an amoeba, which can infest humans as facultative parasite.

It may trigger the primary amoebic meningoencephalitis (PAM), an inflammation of the brain and meninges that has a rapid and often fatal course.

Transmission mainly occurs via contaminated water when swimming or diving. Human-to-human transmission does not occur.

For a successful inactivation of parasites, specific disinfectants effective against parasites are required.
