Fig 2. Inhibition of bacterial adhesion to intestinal epithelial cells.

Bacteria (S. diarizonae, E. coli O138, F4+ or F18+) fluorescently stained as explained in Materials and Methods, and treated with ppIgG in different concentrations (from 100 mg/ml to 0.2 mg/ml) were incubated with IPEC-J2 cells. Binding of bacteria to IPEC-J2 is depicted in relation to non-inhibited bacteria (no ppIgG, set to 100%). One typical experiment is shown.
