A Rare Case of Fatal Balamuthia mandrillaris Encephalitis in a Pediatric Patient: Diagnostic Challenges

Case Reports in Infectious Diseases, Volume 2026, Issue 1, 2026.
Balamuthia mandrillaris is a rare and lethal amoeba that causes granulomatous amoebic encephalitis (GAE), a severe brain infection with a high mortality rate. This manuscript presents a case study of a 5‐year‐old female patient with B. mandrillaris amoebic encephalitis.

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 ...

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

MicrobiologyOpen, 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

Meningoencephalitis due to Naegleria fowleri in cattle in southern Brazil

, 2019
Naegleria fowleri is a free-living amoeba commonly found in the environment, mainly in fresh water and soil. This protozoon is occasionally involved in cases of fatal central nervous system disease in humans and other animal species.

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

Environmental 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.

Mechanisms of Complement Resistance by Pathogenic Naegleria fowleri Amoebae [PDF]

, 1993
The genus Naegleria is composed of a distinct group of free-living amoeboflagellates that include both pathogenic and nonpathogenic species. N. fowleri, the only pathogenic species of Naegleria to be isolated from humans, is the etiological agent of ...

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

Journal 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

Cancer 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.
