Aetiological studies on hospital in-patients with acute diarrhoea in Calcutta

Abstract

Bacterial enteropathogens and rotavirus were sought in 356 cases with acute diarrhoea admitted to the Infectious Diseases Hospital, Calcutta. One or more pathogens were isolated from 74.7% of the cases. Single enteropathogens could be detected from 66% and multiple enteropathogens from 8.7% of the patients. Vibrio cholerae biotype El Tor, rotavirus, V. parahaemolyticus, and enteropathogenic and enterotoxigenic Escherichia coli were the major pathogens detected. Rotavirus was detected from 7.6% of the cases. A higher rate of detection of rotavirus was seen in children younger than two years. Campylobacter jejuni could be isolated from the faeces of six (15%) of 40 cases either as a single pathogen or in association with V. cholerae biotype El Tor.
