A bioactive extract rich in triterpenic acid and polyphenols from Olea europaea promotes systemic immunity and protects Atlantic salmon smolts against furunculosis

ABSTRACT: Deciphering the dietary immunomodulatory effects of a feed additive rich in triterpenic compounds and polyphenols (AQUOLIVE®, NATAC Biotech SL, Spain) on the systemic immune response and disease resistance of Atlantic salmon (Salmo salar L.) smolts.

ORGANISM(S): Salmo salar

Host-parasite transcriptomics during immunostimulant enhanced rejection of salmon lice Lepeophtheirus salmonis by Atlantic salmon Salmo salar

Project description:We investigate the effect of a functional feed for immunostimulation (peptidoglycan extract from bacterial cell wall with nucleotide formulation) on L. salmonis infection levels on Atlantic salmon Salmo salar, and on host and parasite gene expression profiles. Atlantic salmon smolts (~95 g) were fed a control diet, or a low or high dose immunostimulant diet, and then exposed to L. salmonis copepodids in three subsequent exposures. The transcriptome of salmon lice late in the infection attached to either the low dose diet or control diet hosts were compared using a 38K oligonucleotide microarray.

Transcriptional response of Atlantic salmon (Salmo salar) to fish oil vs vegetable oil based diets

Project description:The effect of different diets (i.e. fish oil based vs vegetable oil based) on liver transcription profiles over the life history stages (freshwater and marine phases) of cultured Atlantic salmon (Salmo salar) were explored. Two groups of fish were raised from first feeding on different lipid containing diets; a) the standard 100% fish oil based diet, the other enriched with a blend of vegetable oils (75%) + fish oil (25%). Liver samples were taken from fish at four time points: two freshwater phase (as parr 36 weeks post hatch (wph); as pre-smolts, 52 wph) and two marine phase ( as post-smolts 55 wph; and as adult fish , 86 wph). A total of 96 cDNA microarray hybridisations - TRAITS / SGP Atlantic salmon 17k feature cDNA microarray - were performed ( 2 diets x 4 time points x 6 biological replicates x 2 -dye swap) using a comon pooled reference contol design.

Polyphenols protection against fructose overload

Project description:To decipher the beneficial effects of Polyphenols on health, healthy volunteers were randomized into two groups and were submitted to either a red grape polyphenol rich extract supplemented diet (PP) or a placebo diet (PCB) during 8 weeks. Then they were submitted to a fructose load (3g/kg Fat Free Mass/day) during 7 days. Muscle biopsies were taken before the protocol, 8 weeks after PP or PCB diet and after the 7 days fructose load. We have employed whole genome microarray expression profiling as a discovery platform to identify genes regulated by fructose and to identify the mechanism of action of Polyphenols.

Transcriptional changes in Atlantic salmon (Salmo salar) after embryonic exposure to road salt (NaCl)

Project description:The present study aimed to identify the persistent molecular changes occurring in Atlantic Salmon salmon (Salmo salar) eggs after 24h exposure to high concentrations (5000 mg/L) of road salt at fertilization. Atlantic Salmon (Salmo salar) eggs after fertilization were exposed to high concentrations (5000 mg/L) of road salt for 24 h and used for gene expression analysis.
