Two MP2CL5 Antigen Vaccines from Naegleria fowleri Stimulate the Immune Response against Meningitis in the BALB/c Model

Infection and Immunity, 2023
Naegleria fowleri is an etiological agent that generates primary amoebic meningoencephalitis; unfortunately, no effective treatment or vaccine is available. The objective of this work was to determine the immunoprotective response of two vaccine antigens,

Detection of potentially pathogenic free-living amoebae from the Caspian Sea and hospital ward dust of teaching hospitals in Guilan, Iran

Journal of Water and Health, 2021
Free-living amoebae (FLA) thrive in diverse environmental conditions. The present study aimed to define the FLA distribution from the Caspian Sea as well as from hospital ward dust from Guilan, Iran.

Genotyping and phylogenetic analysis of free-living amoeba (Acanthamoeba and Naegleria) in treated and untreated water in the northeastern provinces of Iran

Water Supply, 2022
Free-living amoebae (FLA) are widely distributed protozoa in natural or man-made aquatic environments without the need for a host organism for survival. Several strains of FLA are known to be pathogenic.

Characterization of Extracellular Vesicles Secreted by a Clinical Isolate of Naegleria fowleri and Identification of Immunogenic Components within Their Protein Cargo

Biology, 2022
Simple Summary Extracellular vesicles are vesicles produced by cells and organisms, capable of developing different functions. In this sense, these vesicles have been involved in communication, in the production of damage during an infection and in the ...

Extracellular Vesicles from Naegleria fowleri Induce IL-8 Response in THP-1 Macrophage

Pathogens, 2022
Extracellular vesicles (EVs) released from pathogenic protozoans play crucial roles in host–parasite communication and disease pathogenesis. Naegleria fowleri is a free-living protozoan causing primary amoebic meningoencephalitis, a fatal disease in the ...

Copper Metabolism in Naegleria gruberi and Its Deadly Relative Naegleria fowleri

Frontiers in Cell and Developmental Biology, 2022
Although copper is an essential nutrient crucial for many biological processes, an excessive concentration can be toxic and lead to cell death. The metabolism of this two-faced metal must be strictly regulated at the cell level. In this study, we investigated copper homeostasis in two related unicellular organisms: nonpathogenic Naegleria gruberi and ...

Naegleria fowleri meningoencephalitis [PDF]

Neurology, 2003
A previously healthy 5-year-old boy presented with severe headache and neck stiffness. On examination, he exhibited somnolence and nuchal rigidity. The results of CSF studies were as follows: red blood cells, 400/mm3; white blood cells, 1,150/mm3 (91% polymorphonuclear cells); glucose level, …
