Fig. 6. Measurement of the abundance of functional bacteria in the feces of prebiotic-treated groups by quantitative PCR. (A, B) Butyrate-producing bacteria; (C-F) lactic-acid bacteria; C: Untreated control, N: AD control (DNCB-induced), P: Zyrtec-positive control (DNCB-induced + Zyrtec), T1: scGOS/lcFOS (DNCB-induced + scGOS/lcFOS), T2: Inulin (DNCB-induced + Inulin), T3: β-glucan (DNCB-induced + β-glucan); *p < 0.05 versus control group, **p < 0.01 versus control group, #p < 0.05 versus negative control group, ##p < 0.01 versus negative control group. Data represent means ± SD of 4 replicates.
