Microbiota changes induced by TNBS and SCFAs-exposed animals. Relative expression of 16S rRNA phylum-specific genes representatives of Betaproteobacteria (A), Actinobacteria (B), Gammaproteobacteria (C), Alphaproteobacteria (D), Bacteroidetes (E), Firmicutes (F), and Fusobacteria (G), from 10 dpf larvae. One-way ANOVA with Tukey's multiple comparisons, *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001. N = 3–4.
