Abstract
Fifty-five strains of Escherichia coli isolated from 51 faeces of Melanesian children with acute diarrhoea in New Caledonia were studied; three diarrhoeas were bloody. For each strain, haemagglutination type, adhesion to rabbit enterocytes, serotype, production of heat-labile (LT) or heat-stable (ST) toxins and identification of colonization factor antigens CFA/I or CFA/II were determined. We identified 48 strains able to attach to rabbit enterocytes; 27 produced enterotoxins (21 strains LT+ and 6 ST+) and 19 had CFA (13 CFA/I and 6 CFA/II). Five serotypes were identified: O6, O78, O80, O114 and O127:B8. One strain, O127:B8, which was able to attach to enterocytes, had CFA/I and produced LT toxin.
