Background: The bacterial pathogens commonly responsible for diarrhea in children under the age of 5 in Zambia were identified and the most effective methods of diagnosis of such infections in laboratories with limited resources, such as those in developing countries, are recommended. Methods: Stool samples were collected from children under the age of 5 years who visited the Diarrhoea Training Unit (DTU) of Zambia University Teaching Hospital in Lusaka, Zambia, between May 1992 and May 1993. A total of 639 children were evaluated for the presence of bacterial infection using standard culture media. The prevalence of bacterial pathogens was compared with that reported from other developing countries Results: Pathogenic strains of Escherichia coli were isolated from 95 (14.9%) children, Shigella species from 65 (10.2%) children, and Vibrio cholerae from 21 (3.3%) children. The presence of visible blood in the feces was an early indicator of the presence of shigellosis.Conclusions: E. coli, Shigellaspecies and Vibrio cholerae were the major causes of bacterial diarrhea in the Zambian children studied. Research is required to determine the prevalence of such enteropathogenic strains. The use of adequate diagnostic procedures is indispensable to appropriate management. The recommendations have been prepared as a manual for the identification of enteropathogenic bacteria to be used in laboratories with limited resources, such as in developing countries.
