我们最近已经证明,培养的人肠HT-29和Caco-2细胞系表达由致炎性C1845大肠杆菌所携带的F1845菌毛粘附素的受体(Kernéis等人,Infect. Immun. 59(1991)4013-4018)。该粘附素属于粘附素家族,包括尿病原性E所携带的Dr血凝素和无菌毛粘附素AFA-1。杆菌在这里,我们调查了实验室E的细胞关联。表达Dr血凝素和无菌毛粘附素AFA-I的大肠杆菌菌株与人培养的肠细胞样或粘液分泌细胞。我们观察到,E。携带这些粘附素的大肠杆菌既粘附于人肠道未分化和分化的液体运输细胞,又粘附于粘液分泌细胞。这一结果有力地表明了尿路致病性大肠杆菌在肠道的高定殖能力。大肠杆菌粘附因子属于粘附素家族。这些结果进一步证实了尿路致病性E的肠道定植。大肠杆菌与泌尿系感染发病机制的粪-会阴-尿道假说有关。
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.
