Transcript expression profiles in the spleens of white sturgeon (Acipenser transmontanum) challenged with Flavobacterium columnare after 30 d of β-glucan (0.3% yeast, Saccharomyces cerevisiae) or normal diet feeding. Expression levels of haptoglobin (A), serum amyloid A (B), serotransferrin (C), tumor necrosis factor alpha (D), interleukin 17 (E), interferon regulator factor 8 (F), major histocompatibility complex II (G) and transforming growth factor beta (H) transcrips are shown as log-fold change for β-glucan-fed fish compared to the control-normal-fed fish for each gene. Data represents mean ± SE (n = 6). Statistically significant differences between treatments at each time point or within the same treatment at different time points is indicated by asterisk (p < 0.05, two-way ANOVA followed by Tukey's multiple comparisons test).
