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.
