Relative mRNA expression levels of mucins in the posterior intestine of gilthead sea bream fed vegetable oils (VO) or fish oil (FO) diets and infected by <i>Enteromyxum leei</i> (RCPT) or kept unexposed to the parasite (CTRL) (Trial 2).

<p>Each bar represents the mean ± the SEM of 6–10 animals. Asterisk indicate statistically significant differences (P<0.05) between CTRL fish fed different diets. Significant differences were also found between each CTRL group and its corresponding RCPT group for the four mucins (not indicated to avoid confusion in symbol interpretations).
