Peyer's patches constitute both an inductive immune site and an enteropathogen invasion route. Peyer's patch mucosae from porcine jejunum were mounted in Ussing chambers, and either Salmonella choleraesuis vaccine strain SC-54 or non-pathogenic rodent and porcine Escherichia coli strains contacted the Peyer's patch mucosa for 90 min. Internalized bacteria were quantified by a gentamicin resistance assay. Monodansylcadaverine (300 microM, luminal addition), an inhibitor of clathrin-mediated endocytosis, significantly inhibited internalization of both E. coli strains relative to tissues untreated with the inhibitor; internalization of SC-54 was unaffected. The actin-disrupting agent cytochalasin D (10 microM, luminal addition), inhibited internalization of pig-adapted E. coli but not that of rodent-adapted E. coli or SC-54. Internalization of SC-54 and non-pathogenic E. coli in Peyer's patches appears to occur through different cellular routes.
