title: Small-intestinal mucosal antibodies against antigens of non-pathogenic luminal or mucosal bacteria in young children with and without diarrhoea.
abstract: Duodenal mucosal antibody against non-pathogenic bacteria, grown either from the luminal juices or the mucosa itself, was demonstrated for the first time in 7 of 8 children with diarrhoea and only 2 of 7 without diarrhoea. Neither group showed significant histological abnormalities on duodenal biopsy. An aetiological relation between the antibody and the persistence of postenteritis diarrhoea is possible.
