Abstract

An adhesion assay with isolated human enterocytes prepared from duodenal biopsies has been developed and tested by using human enterotoxigenic Escherichia coli expressing colonization factor antigens I and II (CFA/I and CFA/II) and type 1 fimbriae. Enterotoxigenic E. coli strains H10407 (CFA/I) and B2C (CFA/II) bound to duodenal enterocytes to a much greater extent (mean of 4.6 and 4.0 bacteria per brush border) than did strain H10407P, a CFA/I- mutant of H10407 (mean of 0.1 bacteria per brush border). Type 1 fimbriae also promoted adhesion of strain H10407P to duodenal enterocytes but attachment was to basolateral rather than brush border surfaces. CFA/I and CFA/II, on the other hand, promoted adhesion only to human enterocyte brush borders.
