“…In particular, the disruption of their morpho-functional properties has been described after exposure to low [104] and high [105] temperatures, pH acidification [106], mechanical stress [107], salinity changes [108], exposure to air [109], harmful algal bloom [110], organic and inorganic contaminants [111]. Nevertheless, some endogenous factors seem to have also an important influence on the modulation of the hemocyte activity, such as age [112], gender [113] and reproductive stage [114]. …”

A variety of bivalve mollusks (phylum Mollusca, class Bivalvia) constitute a prominent commodity in fisheries and aquacultures, but are also crucial in order to preserve our ecosystem’s complexity and function. Bivalve mollusks, such as clams, mussels, oysters and scallops, are relevant bred species, and their global farming maintains a high incremental annual growth rate, representing a considerable proportion of the overall fishery activities. Bivalve mollusks are filter feeders; therefore by filtering a great quantity of water, they may bioaccumulate in their tissues a high number of microorganisms that can be considered infectious for humans and higher vertebrates. Moreover, since some pathogens are also able to infect bivalve mollusks, they are a threat for the entire mollusk farming industry. In consideration of the leading role in aquaculture and the growing financial importance of bivalve farming, much interest has been recently devoted to investigate the pathogenesis of infectious diseases of these mollusks in order to be prepared for public health emergencies and to avoid dreadful income losses. Several bacterial and viral pathogens will be described herein. Despite the minor complexity of the organization of the immune system of bivalves, compared to mammalian immune systems, a precise description of the different mechanisms that induce its activation and functioning is still missing. In the present review, a substantial consideration will be devoted in outlining the immune responses of bivalves and their repertoire of immune cells. Finally, we will focus on the description of antimicrobial peptides that have been identified and characterized in bivalve mollusks. Their structural and antimicrobial features are also of great interest for the biotechnology sector as antimicrobial templates to combat the increasing antibiotic-resistance of different pathogenic bacteria that plague the human population all over the world.

“…20 More studies should be done to explain how the immune system of Mytilus edulis could be affected by spawning. Since sex can also influence the immune and endocrine systems of bivalves, 23,24 it should be included in such studies.…”

“…Intrinsic parameters, such as sex of organisms, could exert an effect on morphometric and functional characteristics of hemocytes in some bivalve species, and therefore sex should be considered during analyses and interpretations of the immune response (Dang et al 2012). In some bivalve species, females showed higher numbers and larger sizes of hemocytes, and higher content of lysozyme (Matozzo & Marin 2010, Dang et al 2012, but in some others species, males showed higher complexity (granules content) of granulocytes, as well higher oxidative capacity in both hyalinocytes and granulocytes (Dang et al 2012).…”

In this study, SOA production (oxidative capacity) showed a tendency to increase in males of Crassostrea corteziensis until 45 min, whereas in females SOA production decreased significantly with increasing time of exposure to thermic stress conditions.…”
