Isolation and Characterisation of Serotype III in Miamiensis avidus (Ciliophora: Scuticociliatida) From Olive Flounder (Paralichthys olivaceus) [PDF]
Journal of Fish Diseases, Volume 49, Issue 2, February 2026.ABSTRACT Miamiensis avidus (Ciliophora: Scuticociliatida, syn. Philasterides dicentrarchi) is a significant pathogen causing scuticociliatosis in olive flounder (Paralichthys olivaceus) in Korea and Japan. In this study, the BB19 strain, isolated from olive flounder, was identified as M.

Insights into mucosal and systemic immune responses of African catfish, Clarias gariepinus, to chilodonellosis: A natural infection study [PDF]
Journal of Fish Biology, Volume 107, Issue 4, Page 1323-1334, October 2025.Abstract A natural parasitic infection with the external ciliate protozoan, Chilodonella hexasticha, was recorded 3 days post‐transportation (PT) in the gills and skin of African catfish (Clarias gariepinus). Infected fish displayed behavioural changes and typical signs of infection.

Extracellular rRNA Profiling Reveals the Sinking and Cell Lysis Dynamics of Marine Microeukaryotes [PDF]
Environmental Microbiology, Volume 27, Issue 8, August 2025.Lytic mortality of marine microeukaryotes was assessed using extracellular rRNA profiling. Cell lysis was elevated in the mesopelagic zone (300–500 m), primarily involving cells that had sunk from the surface layer. ABSTRACT Marine plankton communities consist of numerous species, and their composition and physiological states are closely linked to ...

Seasonal Host Shifts for Legionella Within an Industrial Water‐Cooling System [PDF]
Environmental Microbiology Reports, Volume 17, Issue 4, August 2025.Taxonomic profiling for Legionella (the causative agent of Legionnaires' disease) and protist hosts within a water cooling tower showed seasonal peaks for Legionella that were associated with taxonomic shifts in the protist community. Legionella frequency was tracked using amplicon sequencing (blue line) and serogroup profiling (red line).

Protistan Plankton Responses to Variable Light and Upwelling in the Peruvian Humboldt Current System: Insights Into Community Dynamics Under Environmental Change [PDF]
Ecology and Evolution, Volume 16, Issue 1, January 2026.Our study reveals (based on experiments) the shifts in protistan plankton communities, serving as energy and organic matter source for higher trophic levels if the Humboldt Current System is affected by climate change as predicted by current models. This may have profound effects on fisheries in the Humboldt Current System.

Long Term Copepod Culture Houses a Rich Microbial Eukaryotic Community Including New and Known Symbionts [PDF]
Journal of Eukaryotic Microbiology, Volume 72, Issue 6, November/December 2025.ABSTRACT Copepods, dominant marine zooplankton, are hosts to microbial eukaryotic symbionts, but the copepod eukaryome remains largely unexplored. We used 18S rRNA gene primers with reduced metazoan amplification to identify microbial eukaryotes in a culture of Calanus finmarchicus (Copepoda).

Seasonal Transition in the Dominance of Photoautotrophic and Heterotrophic Protists in the Photic Layer of a Subtropical Marine Ecosystem [PDF]
Environmental Microbiology Reports, Volume 17, Issue 4, August 2025.Amplicon sequencing showed a distinct seasonality in protist communities and functional strategies in a subtropical ecosystem in the Gulf of Aqaba. Temperature and nutrients were major drivers of succession. Comparisons with oceanwide Tara‐Ocean datasets indicated that the summer‐oligotrophic protist assemblages from the Gulf of Aqaba resemble those ...

Efficacy of selected oral chemotherapeutants against Ichthyophthirius multifiliis (Ciliophora: Ophyroglenidae) infecting rainbow trout Oncorhynchus mykiss [PDF]
Diseases of Aquatic Organisms, 2003 The chemotherapeutic efficacy of 6 in-feed compounds against Ichthyophthirius multifiliis Fouquet, 1876 was assessed using experimental infections of rainbow trout Oncorhynchus mykiss (Walbaum) fingerlings. Trial doses of 104 ppm amprolium hydrochloride or 65 ppm clopidol fed to fish for 10 d prior to infection significantly reduced the number of ...
