Aetiological studies on hospital inpatients with secretory diarrhoea in Calcutta.

: Twenty-five cases of all age groups with secretory diarrhoea admitted to the Infectious Diseases Hospital, Calcutta were studied. Bacterial enteropathogens were detected by bacteriological examination of the faeces, in each and every case. The main pathogens detected were Escherichia coli and Vibrio cholerae. V cholerae was more commonly associated with severe illness except in the very young, while Esch coli was equally associated with moderate and severe illness. Multiple isolates were more commonly associated with severe illness and single isolates were more common in illness of moderate severity.
