Figure 4: Expression of immune-relevant genes determined by real-time polymerase chain reaction (PCR) in seabream following a diet with Debaryomyceshansenii L2 plus inulin at week 2. Fold change in gene expression compared with the control fish is expressed. All the genes were considered to be up-regulated if the relative value was above 1 and down-regulated with a relative value below 1. Each bar represents the mean SD of triplicate samples
