Characterization of actin genes in Bonamia ostreae and their application to phylogeny of the Haplosporidia [PDF]

, 2017
Bonamia ostreae is a protozoan parasite that infects the European flat oyster Ostrea edulis, causing systemic infections and resulting in massive mortalities in populations of this valuable bivalve species. In this work, we have characterized B.

The Future of Pathogen Detection in Aquaculture: Miniature Labs, Field‐Compatible Assays, environmental DNA and RNA, CRISPR and Metatranscriptomics

Aquaculture, Fish and Fisheries, Volume 5, Issue 3, June 2025.
ABSTRACT Inland recirculating aquaculture is a thriving food industry providing sustainable and locally sourced high‐quality protein. However, its expansion is accompanied by emerging challenges regarding the spread of pathogens and diseases. Detection and management of pathogens in aquaculture remain underdeveloped compared to other animal farming ...

Spore ornamentation of Minchinia occulta n. sp. (Haplosporidia) in rock oysters Saccostrea cuccullata (Born, 1778) [PDF]

, 2008
A Minchinia sp. (Haplosporidia: Haplosporidiidae) parasite was identified infecting rock oysters and morphologically described by Hine and Thorne (2002) using light microscopy and transmission electron microscopy (TEM).

Investigation of the water environmental DNA/RNA profile for non‐invasive biomonitoring of the fish pathogen Aeromonas salmonicida subsp. salmonicida and detection of immune responses in rainbow trout (Oncorhynchus mykiss)

Environmental DNA, Volume 6, Issue 4, July–August 2024.
Environmental DNA and RNA was used to detect a fish pathogen from water samples. The pathogen could be detected days before fish showed clinical signs of disease and mortality. Abstract Aquaculture industries face challenges in fish production, primarily due to disease occurrence.

Pathogen dispersal can lead to high exposure risk at European flat oyster restoration sites

Communications Earth & Environment
Marine diseases threaten ecosystems and aquaculture, additionally harming endangered species including the European flat oyster (Ostrea edulis). Although international restoration efforts follow biosecurity protocols, ocean currents may transport ...

Bonamia ostreae and Ostrea edulis : a stable host-parasite system in France? [PDF]

, 2006
Bonamiosis due to the intrahaemocytic protistan parasite Bonamia ostreae is a European endemic disease affecting flat oysters Ostrea edulis. After its first description in June 1979 in L'Ile Tudy, Brittany, the parasite rapidly spread to all French oyster farming areas and in other European countries through transfers of live molluscs.

Infection with the protozoan parasite Bonamia ostreae modifies in vitro haemocyte activities of flat oyster Ostrea edulis [PDF]

Fish & Shellfish Immunology, 2009
Bonamia ostreae is an intracellular protozoan parasite, infecting haemocytes of the European flat oyster Ostrea edulis. Oyster defence mechanisms mainly rely on haemocytes. In the present study in vitro interactions between parasites and flat oyster haemocytes were investigated using flow cytometry and light microscopy.

Low internal transcribed spacer rDNA variation in New Zealand Bonamia ostreae: Evidence for a recent arrival

, 2020
Bonamia ostreae is a haplosporidian parasite of oysters that was first reported to occur in the Southern Hemisphere in 2015 in the New Zealand flat oyster Ostrea chilensis. Until that report, B. ostreae had been restricted to populations of O.

Risk of introduction of Bonamia ostreae infected Ostrea edulis in the North Sea

De gewone oester (Ostrea edulis) is de inheemse oestersoort in West Europa. Over de afgelopen jaren is de interesse toegenomen in herstelprojecten van de historische oester populatie in de Noordzee. Als platte oesters in de Noordzee worden uitgezet is er, afhankelijk van de oorsprong van de oesters, risico op introductie van de platte oester parasiet ...
