Probiotic intakes reduced stress response and constipation in zebrafish larvae. (A) Schematic illustration showing experimental design. Larvae were fed Bifidobacterium longum subsp. longum probiotic-based food on 6 and 8 dpf during constant light exposure. (B) Comparison of cortisol concentration between light-stress group and probiotic-feeding light-stress group (n = 12). (C) Relative fold change of crhb mRNA expression (n = 3). Each replicate had 20 zebrafish embryos. (D–F) Lateral images of the fluorescent tracer in the intestinal tracts of zebrafish larvae. Scale bar: 100 μM. (F) Comparison of the number (#) of intestinal contractions in zebrafish larvae. n = 12 for light-stress group, n = 17 for light-stress/B. longum group. * p < 0.05; *** p < 0.001.
