Naegleria
[nā·glēr′ē·ə]
Etymology: F.P.O. Nägler, Austrian bacteriologist, 20th century
a genus of free-living protozoa, found in freshwater, soil, and sewage, that have both an ameboid and a flagellate stage in their life cycle. Certain species, especially N. fowleri, are capable of facultative parasitism, and some strains are highly pathogenic and may cause a highly fatal primary amebic meningoencephalitis. Infection is usually acquired by swimming in water contaminated with the organisms. See also primary amebic meningoencephalitis.

Naegleria
a genus of protozoa in the family Vahlkampfiidae.

Naegleria fowleri
persists in thermally heated swimming pools and causes fatal meningoencephalitis in humans.

Naegleria (nā-glē'rē-ă),
A genus of free-living soil, water, and sewage ameba (order Schizopyrenida, family Vahlkampfiidae) one species of which, Naegleria fowleri, has been implicated as the causative agent of the rapidly fatal primary amebic meningoencephalitis. Infection has been traced to swimming pools (including indoor chlorinated pools); entry is by the nasal mucosa, from which the amebae reach the meninges and brain through the cribriform plate and olfactory nerves. Other soil amebae that have been implicated, although of far less epidemiologic significance, include the genera Acanthamoeba and Hartmanella, the latter is a suspected but unproved causative agent.

Nae·gle·ri·a (nā-glē'rē-ă)
Free-living freshwater and soil ameboflagellates that cause amebic meningitis.

Introduction Primary amebic meningoencephalitis (PAM) is a severe infection of the central nervous system (CNS) caused by Naegleria fowleri, a thermophilic, free-living ameba found worldwide (Visvesvara, Moura, & Shuster, 2007).
In the 2011 cases resulting in death, a pathogen, Naegleria fowleri, also known as "the brain-eating amoeba", infected victims through the nasal tissue.
The amoeba -- Naegleria fowleri -- lives in warm, unclean water.
