Determination of the concentration of TNFα, IFNγ IL-10 and IL-6 in intestinal fluid by ELISA. The samples were taken before the infection for the untreated (C) and L. casei CRL 431(Lc) groups, and 7 and 10 days post challenge for all the experimental groups. The results were expressed as the means ± SD of the concentration of each cytokine in pg/ml. Means for each value without a common letter differ significantly (P < 0.01).
