Naegleria fowleri, an excavate, inhabits soil and water. It is sensitive to drying and acidic conditions, and cannot survive in seawater. The amoeba thrives at moderately elevated temperatures, making infections more likely during summer months. N. fowleri is a facultative thermophile, capable of growing at temperatures up to 46 °C (115 °F). [12]
Naegleria, in contrast to other amoebae, differentiates within two hours into the flagellate state. Pathogenicity can be further confirmed by exposure to high temperature (42 °C): Naegleria fowleri is able to grow at this temperature, but the nonpathogenic Naegleria gruberi is not.

Naegleria fowleri is often included in the group "free-living amoebae", [2] [3] and this species causes a usually fatal condition traditionally called primary amoebic meningoencephalitis (PAM). However, the genus Naegleria is now considered part of the Excavata , not the Amoebozoa, [ 4 ] and is considered to be much more closely related to ...
Despite the possibility of there being Naegleria fowleri in freshwater, there are very few cases of Naegleria fowleri each year, with only three reported cases in 2022. However, Deresinski says ...
Public officials are in the process of eliminating Naegleria Fowleri, a brain-eating amoeba, from two drinking water supplies in Louisiana. Naegleria Fowleri was detected during routine tests last ...
Naegleria / n ɛ ˈ ɡ l ɪər i ə / is a genus consisting of 47 described species of protozoa often found in warm aquatic environments as well as soil habitats worldwide. [1] It has three life cycle forms: the amoeboid stage, the cyst stage, and the flagellated stage, and has been routinely studied for its ease in change from amoeboid to flagellated stages. [1]
A 2-year-old boy from Nevada, died this week from a Naegleria fowleri infection, also known as a brain-eating amoeba, state health officials and his mother said.
