Colostrum and blood mononuclear cells were preincubated or not with EPEC. Indicates differences between phagocytes incubated with bacteria and the control (without bacteria) within each group and sample; + indicates intergroup differences within each treatment (with or not bacteria) and sample; #indicates differences between sample (colostrum and blood) within each treatment (with or not bacteria) and group.
