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 fowleri. N. fowleri invades the central nervous system via the nose, specifically through the olfactory mucosa of the nasal tissues. This usually occurs as the result of the introduction of water that has been contaminated with N. fowleri into the nose during activities such as swimming, bathing or nasal irrigation. [12]
The location and number of amoebas in the water can vary over time within the same body of water.” ... there are very few cases of Naegleria fowleri each year, with only three reported cases in ...
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]
The term "brain-eating amoeba" has been used to refer to several microorganisms: Naegleria fowleri, which causes naegleriasis; Acanthamoeba spp., which causes the slow-acting infection acanthamoebiasis
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 ...
