Characterization of actin genes inBonamia ostreaeand their application to phylogeny of the Haplosporidia [PDF]

Parasitology, 2007
SUMMARYBonamia ostreaeis a protozoan parasite that infects the European flat oysterOstrea edulis, causing systemic infections and resulting in massive mortalities in populations of this valuable bivalve species. In this work, we have characterizedB. ostreaeactin genes and used their sequences for a phylogenetic analysis. Design of different primer sets

Effects of temperature and salinity on the survival of Bonamia ostreae, a parasite infecting flat oysters Ostrea edulis [PDF]

Diseases of Aquatic Organisms, 2009
Bonamiosis due to the intrahaemocytic protistan parasite Bonamia ostreae is a European endemic disease affecting the flat oyster Ostrea edulis. The parasite has been described in various ecosystems from estuaries to open sea, but no clear correlation has yet been demonstrated between disease development and environmental parameters.

Involvement of apoptosis in the dialogue between the parasite Bonamia ostreae and the flat oyster Ostrea edulis

Fish & Shellfish Immunology, 2019
The protozoan parasite Bonamia ostreae has been associated with the decline of flat oyster Ostrea edulis populations in some European countries. Control of shellfish diseases mostly relies on prevention measures including transfer restrictions and stock management measures such as breeding programmes.

Can the protozoan parasite Bonamia ostreae infect larvae of flat oysters Ostrea edulis? [PDF]

Veterinary Parasitology, 2011
Bonamia ostreae is an intracellular protistan parasite affecting flat oysters Ostrea edulis. It can be detected in juveniles but mortalities mainly affect oysters which are more than 2 years old. The parasite is usually observed inside haemocytes and sometimes free, notably in gill epithelia suggesting a parasite release through this organ.

Metabarcoding of Broad‐Diet Nototheniid Fish Stomachs Reveals Newly Detected Antarctic Parasite Signals and Potential Host Associations

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Using 18S rDNA metabarcoding of stomach contents from two Antarctic nototheniid fishes, we detected 242 parasite OTUs. Protists dominated diversity, metazoans dominated abundance, and depth structured assemblages. Novel parasite–host associations and previously unreported pathogenic protists highlight fish metabarcoding as a tool for biodiversity and ...

Potential Genomic Resources and Their Utilization in Edible Oysters

Aquaculture Research, Volume 2026, Issue 1, 2026.
Oysters have recently been recognized globally as a preferred species, not only for their high‐quality meat and sustainable aquaculture practices but also for their environmental value including carbon sequestration and nitrogen removal in aquaculture ecosystems.

Biological invasions: a global assessment of geographic distributions, long‐term trends, and data gaps

Biological Reviews, Volume 100, Issue 6, Page 2542-2583, December 2025.
ABSTRACT Biological invasions are one of the major drivers of biodiversity decline and have been shown to have far‐reaching consequences for society and the economy. Preventing the introduction and spread of alien species represents the most effective solution to reducing their impacts on nature and human well‐being.

Genome‐Wide Population Structure in a Marine Keystone Species, the European Flat Oyster (Ostrea edulis)

Molecular Ecology, Volume 34, Issue 23, December 2025.
ABSTRACT Ostrea edulis, the European flat oyster, was once a widespread economically and ecologically important marine species, but has suffered dramatic declines over the past two centuries. Consequently, there has been a surge in European restoration efforts, many of which focus on restocking as a conservation measure.
