Interactions between Naegleria fowleri and Legionella pneumophila [PDF]

Infection and Immunity, 1985
Using electron microscopy we documented some of the intracellular events that occur in Naegleria fowleri suspended in Page amoeba saline after ingestion of Legionella pneumophila. Photomicrographs showed intracellular vacuoles containing bacteria in the process of binary fission that was accompanied by alignment of mitochondria and ribosome-like ...

Rare Infectious Diseases: Detection and Clinical Implications

iLABMED, Volume 3, Issue 2, Page 148-157, June 2025.
Rare infectious diseases are infections that are uncommon, have a low incidence, and are caused by newly emerging pathogens, cross‐species or ectopic infections, or host immunodeficiencies. The detection and diagnosis of rare infections is one of the main reasons for misdiagnosis and missed diagnosis.

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 ...

A giant virus infecting the amoeboflagellate Naegleria

Nature Communications
Giant viruses (Nucleocytoviricota) are significant lethality agents of various eukaryotic hosts. Although metagenomics indicates their ubiquitous distribution, available giant virus isolates are restricted to a very small number of protist and algal ...

Role of protein arginine methyltransferase 1 in obesity‐related metabolic disorders: Research progress and implications

Diabetes, Obesity and Metabolism, Volume 26, Issue 9, Page 3491-3500, September 2024.
Abstract Obesity has become a major global problem that significantly confers an increased risk of developing life‐threatening complications, including type 2 diabetes mellitus, fatty liver disease and cardiovascular diseases. Protein arginine methyltransferases (PRMTs) are enzymes that catalyse the methylation of target proteins.

Immunization of mice against Naegleria fowleri infection [PDF]

Infection and Immunity, 1977
Naegleria fowleri produces fatal meningoencephalitis in humans and in experimentally infected laboratory animals. The course of the disease in mice is dependent upon the infecting dose of amoebae, route of inoculation, and prior exposure to Naegleria antigens. DUB/ICR mice were immunized by various routes and antigen preparations, held for 21 days, and,

Fossil Geyserite and Testate Amoebae in Geothermal Spring Vent Pools: Paleoecology and Variable Preservation Quality in Jurassic Sinter of Patagonia (Deseado Massif, Argentina)

Geobiology, Volume 22, Issue 5, September/October 2024.
ABSTRACT Geyserite is a type of terrestrial siliceous hot spring deposit (sinter) formed subaerially in proximal vent areas, with near‐neutral pH, alkali chloride discharge fluids characterized by initial high temperatures (~73°C to up to 100°C) that fluctuate rapidly in relation to dynamic hydrology, seasonality, wind, and other environmental ...
