Metabolic Profile Associated With Encystation in Acanthamoeba

Journal of Eukaryotic Microbiology, Volume 72, Issue 5, September/October 2025.
ABSTRACT The genus Acanthamoeba includes widespread protozoa that can cause severe infections in humans. Their ability to form resistant cysts within infected tissues complicates treatment, making it essential to understand the encystation process for developing effective therapeutic strategies.

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.

An investigation into the relationship between intracellular bacteria and Acanthamoeba spp. [PDF]

, 2015
Acanthamoeba is an opportunistic single-celled protist, found ubiquitously in nature. It is the causative agent of the sight-threatening eye disease, Acanthamoeba keratitis (AK), and has been shown to act as a protective harbor for a variety of bacterial

Paulinella acadia sp. nov., a New Photosynthetic Species Isolated From a Brackish Beach in British Columbia (Canada)

Journal of Eukaryotic Microbiology, Volume 72, Issue 5, September/October 2025.
ABSTRACT Plastids in almost all photosynthetic lineages originated from a primary endosymbiosis between cyanobacteria and heterotrophic eukaryotes in an ancestor of Archaeplastida. Strikingly, this event was repeated about a billion years later in an ancestor of photosynthetic Paulinella.

Toric AdS4/CFT3 duals and M-theory Crystals

, 2007
We study the recently proposed crystal model for three dimensional superconformal field theories arising from M2-branes probing toric Calabi-Yau four-fold singularities.

Glissandra oviformis n. sp.: a novel predatory flagellate illuminates the character evolution within the eukaryotic clade CRuMs

Open Biology
Culturing protists offers a powerful approach to exploring eukaryotic diversity, especially for deep-branching lineages. In this study, we cultured and described a novel protist species, named Glissandra oviformis n sp.
