Enteropathogenic agents in children with diarrhoea in rural Zaire.

A systematic study of enteropathogenic agents in the stools of children was carried out in a rural area of Kivu Province in Zaire in June, 1979. 84 inpatients and 271 outpatients with diarrhoea were investigated together with 117 inpatient and 203 outpatient controls without diarrhoea. Campylobacter jejuni was the most frequently recovered pathogen in both inpatients (24%) and outpatients (13.7%). Enterotoxigenic Escherichia coli was the next most common among children presenting as outpatients with diarrhoea (10.3%). Yersinia enterocolitica was isolated for the first time in this region. Rotaviruses were found only in outpatients with diarrhoea, and usually in children under two years of age. C. jejuni and Vibrio cholerae could also be isolated from the faeces of domestic animals living in close contact with these village families. Analysis of the clinical features did not lead to the recognition of a pattern typical of any particular pathogen. Salmonella, Shigella, and enteropathogenic E. coli did not play a significant role in the cases studied.
