Since 2014, mass mortalities of mussels Mytilus spp. have occurred in production areas on the Atlantic coast of France. The aetiology of these outbreaks remained unknown until the bacterium Francisella halioticida was detected in some mussel mortality cases.

Article Synopsis
- The flat oyster, native to Europe, has seen a significant decline in populations in the NE Atlantic due to over-exploitation and diseases like bonamiosis, caused by the parasite
- Limited genetic data have made it difficult to study the Haplosporidian species responsible for this disease
- Researchers have successfully generated the first transcriptome for this non-culturable parasite using a specialized isolation protocol and bioinformatics, which could aid in understanding its biology and developing new diagnostic tools.
Article Synopsis
- Mortality outbreaks in young Pacific oysters, primarily caused by the herpesvirus ostreid herpesvirus 1 (OsHV-1), have significantly impacted oyster farming worldwide.
- Recent studies suggest that autophagy, a cellular degradation process, plays a crucial role in the oyster's response to OsHV-1 infection.
- An experimental study demonstrated that autophagy was activated in various oyster tissues after infection, highlighting different regulatory mechanisms and confirming its importance in fighting the virus.
Article Synopsis
- * Recent research in France used microscopy, PCR, and sequencing to confirm the presence of H. costale in C. gigas during low mortality events in 2019, marking the first verification of this parasite in French oysters.
- * A new TaqMan real-time PCR assay was developed to detect H. costale efficiently, revealing that this parasite has been in French oyster populations since at least 2008,
