EPIDEMIOLOGIC SURVEY OF THE ENTEROPATHOGENIC ESCHERICHIA-COLI ISOLATED FROM CHILDREN WITH DIARRHEA

Escherichia coli was isolated in 382 (94 per cent) of 406 children from 0 to 3 years of age who had been hospitalized for diarrhoea at the Hospital Municipal Salles Neto, Rio de Janeiro. Enteropathogenic Escherichia coli strains were isolated in 67 samples (18 per cent), distributed among the serogronps that were tested as follows: 0111 (33 per cent); 0125 (19 per cent); 0126, 0127, and 0142 (9 per cent); 0128 and 0119 (8 per cent); 055 (5 per cent); 0114 (2 per cent). No strains of EPEC belonging to serogroups 086, 0126, and 0158 were found. Among the samples in which EPEC strains were isolated, 15.0 per cent were children living in dwellings which had piped systems of water supply and drain, whereas with regard to those living in houses without such facilities, this percentage raised to 24 per cent. Similar results were found when the availability of water supply of drainage were taken separately. © 1990 Oxford University Press.
