We have recently demonstrated that cultured human intestinal HT-29 and Caco-2 cell lines express receptors for the F1845 fimbrial adhesin harbored by the diarrheagenic C1845Escherichia coli(Kernéis et al., Infect. Immun. 59 (1991) 4013–4018). This adhesinn belongs to a family of adhesins including the Dr hemagglutinin and the afimbrial adhesin AFA-1 harbored by uropathogenicE. coli. Here we investigated the cell association of laboratoryE. colistrains expressing the Dr hemagglutinin and the afimbrial adhesin AFA-I with human cultured enterocyte-like or mucosecreting cells. We observed that theE. colistrains bearing these adhesins adhere both to human intestinal undifferentiated and differentiated fluid-transporting cells, and to mucus-secreting cells. This result strongly suggests a high capacity of intestinal colonization for the uropathogenicE. coliharboring adhesive factors belonging to the Dr adhesin family. These results further corroborate the intestinal colonization by uropathogenicE. coliof the Dr family related to the fecal-perineal-urethral hypothesis of urinary tract infection pathogenesis.
