Enterotoxigenic enteric bacteria causing secretory diarrhoea.

Two hundred and fifty enteric bacteria isolated from cases of secretory diarrhoea of all age groups were studied for their enterotoxigenicity and prevalence of drug resistance. The principal pathogens were Escherichia coli 44.4%, Vibrio cholerae 28.8%, Salmonella typhimurium 19.2% and Campylobacter jejuni 2.4%. 104 (42.6%) strains were enterotoxigenic; V. cholerae (100%), Escherichia coli (25.2%) and Non-E. coli enterobacteria (6.5%). While 89.3% and 100% Enterotoxigenic Escherichia coli and Salmonella typhimurium strains were multi drug resistant, 40% and 100% respectively showed transfer of R-plasmids to standard receipt strains. In V. cholerae multi drug resistance was observed in only 5.5% strains.
