The present study was conducted to investigate the effect of beta-glucan (derived from Saccharomyces cerevisiae) on the immune response and its protection against an infection of the bacterial pathogen Aeromonas hydrophila in zebrafish (Danio rerio). Zebrafish received beta-glucan by intraperitoneal injection at three different concentrations (5, 2 and 0.5(More)
Zebrafish were used to investigate the expression levels of several antiviral and inflammatory genes (IL-1β, iNOS, TNF-α, TLR3, IFN-I, IFNγ, IRF3, MDA-5, Mx) constitutively and after viral stimulation during early development. We also determined how their expression was affected by changes in the temperature. The antiviral genes were almost completely(More)
We investigated the development of the immune system during the larval stages of the mussel Mytilus galloprovincialis. The ability of trochophore and veliger larvae to phagocytose foreign particles (Escherichia coli and zymosan) was measured. Phagocytosis was detected as early as 24 h post-fertilization (hpf) using flow cytometry and fluorescence(More)
Widespread and large-scale mortalities of bivalve molluscs significantly affect their production. A number of pathogens have been identified as the primary causes of death in oysters or clams, especially bacteria of the genus Vibrio. We evaluated the occurrence, seasonality and infectivity of Vibrio strains associated with natural mussel (Mytilus(More)
Sparc (osteonectin) is a multifunctional matricellular glycoprotein expressed by many differentiated cells. Members of this family mediate cell-matrix interactions rather than acting as structural components of the extracellular matrix (ECM); therefore, they can influence many remodelling events, including haematopoiesis. We have investigated the role of(More)
This work reports the preparation of molecularly imprinted polymers (MIPs) selective to cephalosporin (CF) antibiotics, and their application as molecularly imprinted solid-phase extraction (MISPE) sorbents for the determination of these antimicrobials in milk samples. Several functional monomers and cross-linkers have been screened to select the best(More)
