Enterotoxigenic Escherichia coli and idiopathic diarrhoea in Bangladesh.
Faecal Escherichia coli from Bangalee patients with idiopathic diarrhoea were tested in the Chinese hamster ovary cell (C.H.O.) assay to detect production of thermolabile enterotoxin (L.T.). C.H.O-positive E. coli produce both L.T. and a thermostable toxin (S.T.). C.H.O.-positive strains were found in 19.2% of all cases and in 70% of the most severely ill patients with non-vibrio cholera. E. coli which produce S.T. alone were identified in a third of the C.H.O.-negative cases. Enterotoxigenic E. coli were found in 55% of inpatients with idiopathic diarrhoea and, if an aetiological role is confirmed, may be one of the commonest causes of tropical diarrhoea.
