Isolation and Molecular Identification of Potentially Pathogenic Free‐Living Amoeba in Tap Water Faucets in Quezon City, Philippines

Journal of Parasitology Research, Volume 2026, Issue 1, 2026.
Free‐living amoebae (FLA) are ubiquitous in environmental water and soil, and their presence in water systems for human consumption is a public health concern due to their potential pathogenicity and ability to act as a reservoir for pathogenic bacteria.

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

Primary Amoebic Meningoencephalitis in an Infant due to Naegleria fowleri

Case Reports in Neurological Medicine, 2011
Primary amoebic meningoencephalitis (PAM) caused by free-living amebae Naegleria fowleri is a rare and fatal condition. A fatal case of primary amoebic meningoencephalitis was diagnosed in a 5-month-old infant who presented with the history of decrease ...

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.

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.

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 ...

Lethal encounters: The evolving spectrum of amoebic meningoencephalitis

IDCases, 2019
The free-living amoebae are thermophilic organisms that may play an increasing role among diseases of a warming world. They are uncommon, accidental, yet high consequence pathogens, with differing pathologic syndromes.
