Article Abstract
In bivalves, no clear-cut functional role of microbiota has yet been identified, although many publications suggest that they could be involved in nutrition or immunity of their host. In the context of climate change, integrative approaches at the crossroads of disciplines have been developed to explore the environment-host-pathogen-microbiota system. Here, we attempt to synthesize work on (1) the current methodologies to analyse bivalve microbiota, (2) the comparison of microbiota between species, between host compartments and their surrounding habitat, (3) how the bivalve microbiota are governed by environmental factors and host genetics and (4) how host-associated microorganisms act as a buffer against pathogens and/or promote recovery, and could thereby play a role in the prevention of disease or mortalities.

Exploring the Molluscan Microbiome: Diversity, Function, and Ecological Implications.

Mollusks are among the most ecologically and economically significant invertebrates; yet, their associated microbiomes remain understudied relative to those of other metazoans. This scoping review synthesizes the current literature on the diversity, composition, functional roles, and ecological implications of molluscan microbiomes, with an emphasis on three major groups: gastropods, bivalves, and cephalopods. Drawing on studies from terrestrial, freshwater, and marine systems, we identified the dominant bacterial phyla, including Proteobacteria, Bacteroidetes, and Firmicutes, and explored how microbiota vary across different habitats, diets, tissue types, and host taxonomies.

Shewanella is a diverse genus of more than 100 species known for its metabolic versatility and broad environmental distribution. Strain YIC-542, isolated from the mussel (Mytilus edulis), represents a novel species, and is formally described as Shewanella mytili sp. nov.

Giant clams are key denizens of coral reef ecosystems, forming holobionts through symbiotic relationships with algae of the family Symbiodiniaceae, as in reef-building corals. In this study, we performed a tissue-specific microbiome analysis of the boring giant clam, Tridacna crocea and evaluated the impact of dark-induced bleaching on its outer mantle bacterial community. Using 16S rRNA metabarcoding, Endozoicomonas was identified as the dominant bacterial genus in most tissues, particularly in gills, implying an important contribution to the giant clam holobiont.

Acute hepatopancreatic necrosis disease (AHPND) is a serious bacterial infection affecting penaeid shrimp, caused primarily by Vibrio species harboring the pirAB toxin genes. While AHPND has been studied extensively in shrimp, its potential impact on other marine invertebrates remains largely unexplored. This study evaluates, for the first time, the susceptibility of juvenile lion's paw scallops (Nodipecten subnodosus) to AHPND-associated Vibrio campbellii (AHPND-VP3) strains isolated from Litopenaeus vannamei shrimp outbreaks.

Intertidal ecosystems are physically stressful habitats, with resident organisms often living close to their limits. These limits include the balance between host organisms and microbial partners; a balance that may be tipped by climate change. We simulated intertidal warming in the field by establishing populations of the Sydney rock oyster, Saccostrea glomerata, on black and white concrete tiles, resulting in differing thermal conditions.
