Intestinal spirochaetosis as a cause of longstanding diarrhoea.

This paper deals with the clinical history, the histopathological and scanning electron microscopy (SEM) pictures, treatment and follow up of four cases of intestinal spirochaetosis. Diarrhoea was a prominent symptom in all cases but distension and vague abdominal trouble were also present. It is suggested that heavy infestation of the gut surface epithelium by spirochaetes acts as a barrier for the normal absorptive processes and leads to diarrhoea.
