Summary: Phage therapy shows promise in reducing larval oyster mortalities caused by Vibrio coralliilyticus and Vibrio tubiashii. The efficacy of phage therapy depends on the types and quantities of phages used, as well as the species and strains of target vibrios.

Summary: This study evaluated the virulence of V. coralliilyticus strains against oyster larvae and coral, and found differences in virulence levels between different hosts. In the comparison of known virulence factors, factors that are not crucial for oyster infections were identified. Additionally, strain H1 was found to be non-virulent to coral compared to other strains. This research enhances our understanding of the virulence of different V. coralliilyticus strains and helps assess their potential threat to marine environments and shellfish industries.

Summary: By applying a combination of three probiotic strains to oyster larvae infected with Vibrio coralliilyticus, the researchers found that the survival rate of the larvae significantly improved compared to using individual probiotics. Additionally, a single application of the probiotic combination also increased the metamorphosis success rate of the larvae.

Summary: Long-lasting high temperature and bacterial exposure are critical factors leading to oyster mass mortality in summer. This study investigated the effects of high-temperature exposure and Vibrio alginolyticus infection on Pacific oyster mortality. Results showed that high temperature reduced survival of Vibrio-infected oysters significantly. High temperature disrupted the structure of infected oyster's digestive gland microbiota and increased potentially pathogenic bacteria abundance.

Summary: Yeast cells and their cell wall components, especially beta-glucans, have strong immunostimulatory effects on bivalves. However, it is unclear whether long-term use of yeast contributes to prolonged immune activity in bivalves. Understanding these innate immune mechanisms is important for developing feeding strategies and disease prevention in hatcheries and nurseries. This study investigated the immunostimulatory effect of continuous dietary supply of a yeast mutant on Crassostrea gigas juveniles and its protective effect against Vibrio coralliilyticus infections.

Summary: The rapid growth of Pacific oyster aquaculture industry in China has led to the emergence of mass mortalities. The study found that OsHV-1, Vibrio natriegens, and Vibrio alginolyticus pose potential risks to the industry.

Summary: Marine bivalves account for 14% of global aquaculture production, with oysters representing about 33% of this production. Disease outbreaks caused by Vibrio coralliiyticus pose a major problem in oyster hatchery production. This study demonstrates that selective breeding can enhance the resistance of oyster larvae to Vibrio coralliiyticus, but multiple generations of breeding are expected for significant improvement.

Summary: This study examines the immunostimulatory capacity of yeast cells in bivalves and finds that the cell wall components play a crucial role in immune activation. Feeding bivalves with feed containing Amnn9 can significantly enhance their resistance against bacterial infections.

Summary: In this study, researchers identified a complete mitophagy pathway in the Pacific oyster by screening the components of the pathway and comparing them to those found in humans. This discovery contributes to the understanding of mitochondrial autophagy in mollusks.

Summary: The study found that ocean acidification negatively affects the development and immune response of Pacific oyster larvae. Interestingly, low pH levels were shown to enhance certain energy production and cell signaling pathways, while prominently suppressing some immune response pathways.

Summary: This study investigated the water quality parameters, abundance of larval food, and success of larval settlement during the oyster spat collection period in Hiroshima Bay. Metabarcoding analysis revealed the species composition of phytoplankton that serve as essential food for oyster larvae. The findings provide insights into the favorable environmental conditions and key food sources for sustainable oyster farming in the bay.

Summary: The study found that the immunity in the early stages of Pacific oyster larvae is not strong enough to prevent vibriosis, with Vibrio strains first colonizing the digestive system and rapidly proliferating, leading to necrosis in the larval digestive system.

Summary: This study investigates the synergistic effect of low salinity stress and pathogen infection on the mortality of Pacific oysters. The results show that low salinity stress affects microbial composition and immune response of infected oysters, suggesting that it may trigger immune dysregulation and contribute to oyster mass mortality.

Summary: In this study, we evaluated the impact of ploidy in Crassostrea gigas oysters on contamination with indigenous Vibrio parahaemolyticus (Vp) and on the accumulation and depuration of Vp in laboratory experiments. The results showed that ploidy did not significantly influence contamination by indigenous Vp, although triploid oysters had a lower contamination trend in November. The pathogenic profiles of indigenous Vp varied between seasons, and depuration was higher during the summer months.

Summary: This study evaluated the specificity of four Halobacteriovorax strains against clinically relevant Vibrio parahaemolyticus strains and found that Halobacteriovorax exhibited excellent predatory activity regardless of the origins of the predator or prey. The broad infectivity of Halobacteriovorax towards pathogenic strains of V. parahaemolyticus makes it a strong candidate for enhancing seafood safety.
