Naegleria fowleri and Naegleria gruberi 20S proteasome: identification and characterization

European Journal of Cell Biology, 2020
The Naegleria are ubiquitous free-living amoebae and are characterized by the presence of three phases in their biological cycle: trophozoite, cyst and flagellate. Of this genus, only Naegleria fowleri has been reported as pathogenic to humans. The proteasome is a multi-catalytic complex and is considered to be the most important structure responsible ...

Naegleria fowleri from Pakistan Has Type-2 Genotype

Iranian Journal of Parasitology, 2022
Background: Primary amoebic meningoencephalitis (PAM) is an acute and fulminant CNS infection caused by Naegleria fowleri. Recreational activities and ritual ablution with contaminated warm fresh water are the main reason of PAM.

Biology and pathogenesis of Naegleria fowleri [PDF]

Acta Tropica, 2016
Naegleria fowleri is a protist pathogen that can cause lethal brain infection. Despite decades of research, the mortality rate related with primary amoebic meningoencephalitis owing to N. fowleri remains more than 90%. The amoebae pass through the nose to enter the central nervous system killing the host within days, making it one of the deadliest ...

First identification of Naegleria species and Vahlkampfia ciguana in Nile water, Cairo, Egypt: Seasonal morphology and phylogenetic analysis

Journal of Microbiology, Immunology and Infection, 2020
Background/Purpose: In Egypt, there is a scarcity of data concerning Naegleria (N.) family, with a shortage of phylogenetic studies. This study's aim was molecular detection, sequencing and phylogenetic analysis of morphologically identified Nagleria and

Naegleria gruberi metabolism

International Journal for Parasitology, 2011
The completion of the genome project for Naegleria gruberi provides a unique insight into the metabolic capacities of an organism, for which there is an almost complete lack of experimental data. The metabolism of Naegleria seems to be extremely versatile, as can be expected for a free-living amoeboflagellate, but although considered to be fully ...

Agglutination of Naegleria fowleri and Naegleria gruberi by antibodies in human serum [PDF]

Journal of Clinical Microbiology, 1983
The capability of serum samples from 423 human subjects to agglutinate rounded cells of Naegleria fowleri nN68 was assessed. Sera from the umbilical cords of seven infants failed to agglutinate N. fowleri cells. The median agglutination titer was 1:4 for sera from children through age 4 years, 1:8 for sera from juveniles 5 to 15 years of age, and 1:16 ...

Genomics and transcriptomics yields a system-level view of the biology of the pathogen Naegleria fowleri

BMC Biology, 2021
The opportunistic pathogen Naegleria fowleri establishes infection in the human brain, killing almost invariably within 2 weeks. The amoeba performs piece-meal ingestion, or trogocytosis, of brain material causing direct tissue damage and massive ...

Ultrastructure of Naegleria fowleri enflagellation [PDF]

Journal of Bacteriology, 1981
Amoebae of Naegleria fowleri nN68 became elongated flagellated cells 150 to 180 min after subculture to non-nutrient buffer. N. fowleri NF69 did not become elongated or flagellated under these conditions. Electron microscopic examination of N. fowleri confirmed that it is a typical eucaryotic protist with a distinct nuclear envelope and prominent ...
