[Prevalence of the enterotoxigenic Escherichia coli colonization factors CFA/I, CFA/II and E8775 isolated in the South Pacific (New Caledonia, Republic of Vanuatu and Wallis and Futuna)].
We tested the expression of adherence properties of enterotoxigenic Escherichia coli (ETEC) strains isolated in New-Caledonia, Vanuatu and Wallis and Futuna by examining for the presence of colonization factor E8775 using an agglutination test and an immuno-diffusion technique with specific antisera. Approximately 19% of ETEC strains possessed CFA/I and 21% a CFA/II. The E8775 antigen was found on 1.8% of the strains. This last factor was found on strains of the serogroup 025 from Vanuatu. Two strains 078 usually CFA/I+ possessed a CFA/II and three strains of the serogroup 0126 possessed a CFA/I. The results of this study emphasis the need to continue the search for other mechanisms of adhesion used by ETEC strains without any of the three factors of colonization.
