Anti-porcine antibody neutralization and adherence inhibition. Pig serum, fecal resuspension, and intestine wash samples were examined for neutralizing activity against CT toxin and inhibiting adherence against K88 fimbrial and F18 fimbrial E. coli bacteria. Neutralization against CT was examined using T-84 cells and a cyclic AMP ELISA enzyme immunoassay (EIA) kit (Assay Design). Adherence inhibition against K88ac fimbrial bacteria was evaluated using porcine intestinal cell line IPEC-J2 expressing K88ac receptors and the K88ac fimbrial 3030-2 ETEC strain, whereas inhibition against F18 was examined with porcine intestinal cell line IPEC-1 which expresses F18 receptors and the F18 fimbrial E. coli strain 8516. Bars and error bars represent means and standard deviations. **, P < 0.01.
