New European Stands of Paramecium pentaurelia, Paramecium septaurelia, and Paramecium dodecaurelia, Genetic and Molecular Studies

open access: yesFolia Biologica, 2005
New stands of rare species of the Paramecium aurelia complex were found in Europe, i.e. P. pentaurelia and P. dodecaurelia in Italy and P. septaurelia in Germany. The species were identified by mating reactions with the standard strains of each species.

The Romantic Discovery of Radiolaria in the Ocean

open access: yesJournal of Eukaryotic Microbiology, Volume 73, Issue 1, January/February 2026.
ABSTRACT Radiolaria are unicellular marine organisms (protists) that have been drifting in oceanic plankton for hundreds of millions of years. These mineral architects can build extraordinarily complex skeletons, which fascinated and puzzled naturalists observing water samples through rudimentary microscopes.

The evolutionary conserved proteins CEP90, FOPNL, and OFD1 recruit centriolar distal appendage proteins to initiate their assembly.

open access: yesPLoS Biology, 2022
In metazoa, cilia assembly is a cellular process that starts with centriole to basal body maturation, migration to the cell surface, and docking to the plasma membrane.

Molecular epidemiology of African sleeping sickness [PDF]

open access: yes, 2009
Human sleeping sickness in Africa, caused by Trypanosoma brucei spp. raises a number of questions. Despite the widespread distribution of the tsetse vectors and animal trypanosomiasis, human disease is only found in discrete foci which periodically give ...

My favorite cell—Paramecium [PDF]

open access: yesBioEssays, 2002
AbstractA Paramecium cell has a stereotypically patterned surface, with regularly arranged cilia, dense‐core secretory vesicles and subplasmalemmal calcium stores. Less strikingly, there is also a patterning of molecules; for instance, some ion channels are restricted to certain regions of the cell surface.

Database Release: PPSDB, a Linked Open Data Knowledge Base for Protist–Prokaryote Symbioses

open access: yesJournal of Eukaryotic Microbiology, Volume 72, Issue 6, November/December 2025.
ABSTRACT As the ecological and evolutionary importance of symbiotic interactions between protists (microbial eukaryotes) and prokaryotes (bacteria and archaea) is better appreciated, keeping an overview of their diversity and the literature becomes a growing and ongoing challenge.

All Organisms Can Be Anesthetized, but There's No Point?

open access: yesBioEssays, Volume 47, Issue 10, October 2025.
ABSTRACT Because of their interest in medicine, most studies on anesthesia have historically focused on the nervous systems of animals. This has often led to the neglect of the fact that all life forms have the potential to be anesthetized. Anesthetics target proteins, such as four‐domain voltage‐dependent Na+/Ca2⁺ channels (4D‐NaV/CaV) and glutamate ...

Genome-wide identification and functional analysis of metallothionein family genes in response to cadmium/copper exposure in the unicellular eukaryote Paramecium

open access: yesEcotoxicology and Environmental Safety
Metallothioneins (MTs) comprise an exceptionally heterogeneous protein family with cysteine-rich domains playing crucial roles in metal detoxification for eukaryotes, including protists.

Monitoring Alien Species Diversity in Ballast Water Based on Environmental DNA Metabarcoding

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
This study applied environmental DNA (eDNA) metabarcoding to assess alien species in ballast water from ships at Dongjiakou Port, Qingdao, identifying 41 alien species including three invasives. The findings demonstrate the effectiveness of eDNA as a noninvasive tool for monitoring ballast water biodiversity and offer valuable insights for managing the

Cross-Generational Effects and Non-random Developmental Response to Temperature Variation in Paramecium

open access: yesFrontiers in Cell and Developmental Biology, 2020
Unicellular organisms such as ciliates are largely neglected in research on adaptive developmental plasticity, although their nuclear dualism offers ideal circumstances to study development outside an embryonic context.
