OmpA variants affecting the adherence of ulcerative colitis-derived Bacteroides vulgatus.

Abstract excerpt

To investigate the adhesion factor of Bacteroides vulgatus derived from ulcerative colitis (UC), we isolated B. vulgatus strains from the large intestinal mucosa of UC patients and non-UC individuals, and examined their adherence to tissue-cultured cells. The adherence to tissue-cultured cells in UC-derived strains (36.5 +/- 7.9 %) was higher than that in non-UC-derived strains (13.2 +/- 7.7 %). PCR and...
