Bacterial diseases in marine bivalves
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Travers, Marie-agnes; Miller, Katherine Boettcher; Roque, Ana; Friedman, Carolyn S.
Bivalve aquaculture is seriously affected by many bacterial pathogens that cause high losses in hatcheries as well as in natural beds. A number of Vibrio species, but also members of the genera Nocardia and Roseovarius, are considered important pathogens in aquaculture. The present work provides an updated overview of main diseases and implicated bacterial species affecting bivalves. This review focuses on aetiological agents, their diversity and virulence factors, the diagnostic methods available as well as information on the dynamics of the host-parasite relationship.

Vitamin A supplementation enhances Senegalese sole (Solea senegalensis) early juvenile’s immunocompetence: new insights on potential underlying pathways
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)

Senegalese sole (Solea senegalensis) has been considered since the 1990´s to be a promising flatfish species for diversifying European marine aquaculture. However, pathogen outbreaks leading to high mortality rates can impair Senegalese sole commercial production at the weaning phase. Different approaches have been shown to improve fish immunocompetence; with this in mind the objective of the work described herein was to determine whether increased levels of dietary vitamin A (VA) improve the immune response in early juveniles of Senegalese sole. For this purpose, Senegalese sole were reared and fed with Artemia metanauplii containing increased levels of VA (37,000; 44,666; 82,666 and 203,000 total VA IU Kg-1) from 6 to 60 days post-hatch (early juvenile...
