Frequency of enterovirulent Escherichia coli in diarrhoeal disease in The Netherlands.
To assess the role of enterovirulent Escherichia coli in The Netherlands, faecal samples of 279 patients (108 children, 171 adults) with diarrhoea and 100 healthy controls were investigated in a prospective study. Enterovirulent Escherichia coli were identified by hybridization with five different non-radioactively labelled DNA probes specific for enteropathogenic Escherichia coli (EPEC), verocytotoxin producing Escherichia coli (VTEC) and enterotoxigenic Escherichia coli (ETEC). The rate of isolation of EPEC was 6.5% in patients with diarrhoea and 2.0% in asymptomatic persons. During the study period, no VTEC were isolated from patients with diarrhoea. ETEC were isolated from two persons, both of whom had experienced diarrhoea and had returned from travel in (sub)tropical areas. Our results suggest that diarrhoea is sporadically caused by ETEC among the indigenous population of The Netherlands, and is mainly associated with travel in endemic areas. Furthermore, the presence of EPEC probe-positive strains in the stool need not always be accompanied by symptoms of diarrhoea.
