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 ...

Neuroinfecção por Naegleria fowleri:

Revista 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

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 ...

Experimental meningoencephalitis by Naegleria fowleri in mice

The Korean Journal of Parasitology, 1984
Experimentally, primary amoebic meningoencephalitis (PAM) is induced by Naegleria fowleri in mouse and development of PAM may be influenced by the strain, weight and sex of mouse, and inoculum size of N. fowleri trophozoite. In this paper, the effect of these factors on PAM development of mouse was studied. N.

Isolation of Naegleria lustrarea n. sp. (Excavata, Discoba, Heterolobosea) from the feces of Ambystoma annulatum (Ringed Salamander) in Northwest Arkansas

Journal of Eukaryotic Microbiology, Volume 71, Issue 4, July/August 2024.
Abstract The salamander, Ambystoma annulatum, is considered a “species of special concern” in the state of Arkansas, USA, due to its limited geographic range, specialized habitat requirements and low population size. Although metazoan parasites have been documented in this salamander species, neither its native protists nor microbiome have yet been ...

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 ...

Recommendations for reproducibility of cerebrospinal fluid extracellular vesicle studies

Journal of Extracellular Vesicles, Volume 13, Issue 1, January 2024.
Abstract Cerebrospinal fluid (CSF) is a clear, transparent fluid derived from blood plasma that protects the brain and spinal cord against mechanical shock, provides buoyancy, clears metabolic waste and transports extracellular components to remote sites in the brain.
