Normal, the uninfected-untreated control. Negative control, the infected-untreated control. Loperamide, the infected group with Loperamide-treatment (10 mg/kg). The 5, 10 and 15% GOS were the infected groups treated with corresponding concentration of GOS at a dose of 10 mL/kg, respectively. * P < 0.05 and ** P < 0.01, compared with the negative control. a, b, c Different letters indicate significant differences existed among the three GOS groups (P < 0.05).
