[Is there a connection between infection with Yersinia enterocolitica and regional enteritis? (Preliminary...

After a brief description of the micro-biological, pathological, anatomical and clinical picture of infections with Yersinia enteroclitica, attention is drawn to the striking radiological similarity between three patients with Yersinia infection and regional enteritis (Crohn's disease). Whilst the radiological findings due to Yersinia infection usually resemble the group of so-called non-sclerosing ileitis (Golden) they occasionally differ from this group and resemble the findings in Crohn's disease. In each case the infection was confirmed bacteriologically. The underlying pathology has not been elucidated and it is doubtful whether there is any connection with Crohn's disease.
