[Acute Campylobacter colitis].

Biopsies of colon mucous membrane obtained at colonofibroscopy of 16 adult patients with colon campylobacteriosis were studied. Acute diffuse colitis was found in all cases. Exudative inflammation with hemorrhagic component and microerosion formation was found up to day 10 of the disease. Catarrhal inflammation was observed from day 10-16 during the period of convalescence. Abundant infiltration of tunica propria with eosinophylic leucocytes is a peculiar feature of colon campylobacteriosis. This, together with a diffuse character of inflammation, makes a difference with Shigella colitis. Complete normalization of the mucosa does not occur within 16 days.
