Chamigrane-Type Sesquiterpenes from Laurencia dendroidea as Lead Compounds against Naegleria fowleri

open access: yesMarine Drugs, 2023
Naegleria fowleri is an opportunistic protozoon that can be found in warm water bodies. It is the causative agent of the primary amoebic meningoencephalitis.

Detection of Microbial Contaminants in Water: Conventional Methods, Pragmatic Alternatives, and Nanosensing Techniques

open access: yesMicrobiologyOpen, Volume 14, Issue 6, December 2025.
Conventional culture and immunological methods of detecting bacterial water contaminants have some limitations. There are alternative pragmatic methods which are more efficient and faster in the detection of bacteria in water, especially nanosensors. ABSTRACT The complexities of microbial detection and conventional enumeration necessitates the adoption

Naegleria fowleriin Well Water

open access: yesEmerging Infectious Diseases, 2008
To the Editor: Naegleria fowleri, a protozoon found in hot springs and warm surface water, can cause primary amebic meningoencephalitis in humans. A survey of drinking water supply wells in Arizona determined that wells can be colonized and may be an unrecognized source of this organism that could present a human health risk. N.

Temporal and Spatial Survey on the Abundance of Amoebae and Bacteria in an Estuary and the Role of Environmental Parameters

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 5, October 2025.
Free‐living amoebae and bacteria were monitored along a salinity gradient over 1 year. Naegleria and Vibrio were the most represented genera, with salinity and dissolved oxygen identified as key factors structuring amoebae diversity and associated bacterial communities under changing environmental conditions.

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

open access: yesEuropean 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 ...

A Deeply Branching Lineage in Heterolobosea (Discoba) With Multiflagellated and Multigrooved Life Stages

open access: yesJournal of Eukaryotic Microbiology, Volume 72, Issue 5, September/October 2025.
ABSTRACT Several distantly related, deep‐branching lineages within the eukaryotic tree of life share what is known as the “typical excavate” morphology. This cell architecture includes a suspension‐feeding ventral groove, supported by complex and specific structures of the cytoskeleton, and a vane‐bearing posterior flagellum.

Flavonoids as Promising Akt1 Inhibitors in Cancer Medicine: Insights From Molecular Docking, Dynamics, DFT Calculations, and In Vitro Validation

open access: yesCancer Reports, Volume 8, Issue 8, August 2025.
ABSTRACT Background The PI3K/Akt/mTOR signaling pathway is commonly deregulated in different types of cancers, contributing to tumor proliferation, persistence, and resistance to treatment. Akt1, a crucial kinase within this pathway, plays a critical role in tumor progression and the occurrence of therapeutic resistance.

Virulence-related protein synthesis in Naegleria fowleri [PDF]

open access: yesInfection and Immunity, 1991
Protein synthesis patterns of the low-virulence Naegleria fowleri LEE strain from axenic culture, the same strain after mouse brain passage to increase virulence, and the same strain after growth on bacteria were studied. Comparisons of accumulated proteins, in vivo-synthesized proteins, and in vitro-synthesized proteins translated from poly(A)+ mRNA ...

Luminal Phospholipase D Attacks Bacterial Membranes in Dictyostelium discoideum Phagosomes

open access: yesMolecular Microbiology, Volume 124, Issue 1, Page 54-65, July 2025.
This study shows that PldX, a luminal Phospholipase D, is necessary for the efficient destruction of ingested Klebsiella pneumoniae bacteria in Dictyostelium discoideum phagosomes. PldX and the AlyL lysozyme together attack the bacterial membrane and permeabilize it. To date, the molecular substrate of PldX remains to be determined. ABSTRACT Phagocytic

Neuroinfecção por Naegleria fowleri:

open access: yesRevista Neurociências, 1999
As amebas de vida livre são seres vivos que se distribuem amplamente no planeta e, em determinadas circunstâncias, podem provocar infecções em animais, dentre os quais o Homo sapiens sapiens. Neste âmbito, vem merecendo destaque a espécie Naegleria fowleri, capaz de desencadear quadros extremamente graves, habitualmente de difícil abordagem diagnóstica
