First record of an epibiont protozoan Epistylis sp. (Ciliophora, Peritrichia) attached to Ergasilus chelangulatus (Ergasilidae) in Brazil

Brazilian Journal of Biology
In the present paper, we described the first record of an epibiont protozoan Epistylis sp. Ehrenberg, 1830 (Ciliophora, Peritrichia) attached to Ergasilus chelangulatus Thatcher and Brasil-Sato, 2008, parasite of Pimelodus maculatus Lacépède, 1803 in ...

IMMUNIZATION TRIALS AGAINST ICHTHIOPHTHIRIUS MULTIFILIIS FOUQUET (CILIOPHORA) IN FISH [PDF]

Assiut Veterinary Medical Journal, 1999
Traditional methods of control using chemical treatments are not always effective. They can be costly, cause problems of pollution and of drug resistance in the pathogen, and they may be subjected to prohibitive legilisation.

Widespread Association of Ciliates Colonizing Gills of Shrimps Inhabiting Vents and Seeps Across the Pacific Ocean

Journal of Eukaryotic Microbiology, Volume 73, Issue 5, September/October 2026.
ABSTRACT Bacterial symbiosis is well‐documented in chemosynthesis‐based ecosystems, but associations with microeukaryotes remain overlooked. In this study, using scanning electron microscopy and 18S rDNA barcoding, we investigate the presence, diversity, and biogeographic patterns of ciliate epibionts associated with two deep‐sea caridean families ...

Functional Links Between Leaf Traits, Soil Properties, and Aboveground Biomass Along an Altitudinal Gradient in Chitwan, Nepal

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Resource‐acquisitive leaf traits enhance aboveground biomass accumulation, whereas structural traits constrain it. Elevation and soil properties shape trait expression and biomass across the gradients. ABSTRACT Altitudinal gradients strongly influence plant species diversity and functional trait expression in forest ecosystems.

A revised delimitation of Dorstenia and allied genera (Moraceae), supported by phylogenomics and morphology

TAXON, Volume 75, Issue 4, August 2026.
Abstract Recent phylogenetic studies have called into question the present broad circumscription of Dorstenia (Moraceae), a genus of shrubs and herbs found largely in Africa and the Neotropics. This study presents an updated phylogenomic analysis of Dorstenia and allied genera, reviews the morphology of these taxa, and proposes a revised delimitation ...

Molecular phylogenetics of Thymelaeaceae‐Thymelaeoideae: Resolving the paraphyly of Gnidia and a new monophyletic generic classification for the group

TAXON, Volume 75, Issue 4, August 2026.
Abstract Earlier phylogenetic analyses of the family Thymelaeaceae using combined plastid (matK, rbcL, rps16, trnL‐F) and nuclear (ITS) regions showed that the African‐Malagasy genus Gnidia was extensively polyphyletic in relation to the southern African genera Lachnaea, Passerina and Struthiola, as well as to other Southern Hemisphere genera such as ...

Geographic Variability of Fish Carcass–Associated Microbial Communities

Environmental Microbiology Reports, Volume 18, Issue 4, August 2026.
When sardine carcasses (A) were deployed across seven Japanese tidal flats (B), both bacterial (D) and ciliophoran assemblages (C) varied substantially among sites. Yet, carcass‐associated shifts (blue) were overshadowed by regional variation (red), indicating that local species pools and environmental conditions—rather than carcass inputs alone ...

Genome-wide identification and characterization of cytochrome P450 monooxygenase genes in the ciliate Tetrahymena thermophila

BMC Genomics, 2009
Background Cytochrome P450 monooxygenases play key roles in the metabolism of a wide variety of substrates and they are closely associated with endocellular physiological processes or detoxification metabolism under environmental exposure.
