Beschreibungen/Notizen
Escherichia coli isolates from all surveillance patients ⩽ 20 months of age seen for diarrhoea at the Dhaka Clinical Treatment Facility of the International Centre for Diarrhoeal Disease Research, Bangladesh between March 1 and August 31, 1988, were collected and hybridized with DNA probes to assess the potential importance of diarrhoeagenic
E. coli among paediatric patients in Bangladesh. of 396 patients evaluated, 18% were infected with enteropathogenic
E. coli (EPEC) adherence factor (EAF)-positive
E. coli, 23% were infected with enterotoxigenic
E. coli (ETEC), 9% were infected with Shiga-like toxin-positive
E. coli, and 13% were infected with diffuse adhesiveness-positive
E. coli. None were infected with enteroinvasive
E. coli. Ten percent of patients were colonized with more than one type of potential diarrhoeagenic
E. coli. The majority of EAF-positive isolates were of traditional EPEC O:H serotypes. Although this was not a case-control study, the large number of EPEC and ETEC, which are recognized enteric pathogens, suggests these organisms are important causes of diarrhoeal diseases in this pediatric population.
