In addition we tried to identify Campylobacter inclusions by means of immunohistochemistry and electron microscopy as evidence for invasion of the colonic mucosa. The results show that the majority of patients with Campylobacter colitis have the histological picture of acute infectious colitis with increased numbers of IgA and IgM containing plasma cells in the colonic mucosa in contrast with patients with active chronic inflammatory bowel disease who show increases of IgA and IgG (ulcerative colitis) or IgA-, IgM and IgG containing plasma cells (M Crohn) in their colonic biopsies. The results of immunohistochemical stainings with Campylobacter antiserum show invasion of Campylobacter in the colonic mucosa. These findings were confirmed ultrastructurally.
