[Causes of infectious gastro-enteritis in children in Dakar]

Abstract

Between February 1983 and May 1988, 1,157 stools from children aged under 15 years presenting with diarrhoea and admitted to a paediatric hospital in Dakar, Senegal, were examined for the presence of bacterial and parasitic agents. We looked for Campylobacter and rotavirus in only 245 and 111 samples respectively. Enterobacteria were detected most frequently (162/264; 61.3 per cent). Among these, we found 92 (34.8 per cent) strains of enteropathogenic E. coli; 40 strains (15.1 per cent) of Salmonella spp. and 30 strains (11.3 per cent) of Shigella spp. V. cholerae was present in only 2 faecal specimens (0,7 per cent). Eighty-one (30.6 per cent) parasitic agents were isolated, including a high proportion (13.6 per cent) of flagellae. Campylobacter jejuni and retroviruses were found in 2 (0.8 percent) and 15 (13.5 percent) stool respectively. The frequency with which these enteropathogenic agents were isolated remains in keeping with the global situation usually observed in Dakar for several years.
