Abstract
Certain strains of enteroaggregative Escherichia coli express an outer membrane-associated protein, involved with the adhesion of these bacteria to HEp-2 cells. Strains of enteroaggregative E. coli hybridising with DNA probes for aggregative adhesion, diffuse adhesion and aggregative adhesion fimbriae II expressed an outer membrane-associated protein of 18 kDa regulated by magnesium ions. Strains hybridising with the aggregative adhesion probe only expressed a 20-kDa outer membrane-associated protein regulated by calcium and magnesium. The present study describes two populations of enteroaggregative E. coli which appear to adhere to HEp-2 cells by expressing antigenically distinct, negatively charged membrane-associated proteins.
