n = 7. Data are the mean ± SEM. NC no tannic acid treatment or NE infection, PC NE infection + 0 mg/kg tannic acid, PTA1 NE infection + 250 mg/kg tannic acid, PTA2 NE infection + 500 mg/kg tannic acid, PTA3 NE infection + 750 mg/kg tannic acid, PTA4 NE infection + 1,000 mg/kg tannic acid

¹Body weight and F/G P values obtained from ANOVA; the P-value of mortality was obtained by chi-square test; ²P-values obtained using contrast trend analysis. ^a^–^cDifferent lower case letters in the same column indicate significant differences (P < 0.05)
