To clarify the role played by Bacteroides vulgatus in the pathogenesis of ulcerative colitis, the serum antibody titer to the outer membrane protein of B. vulgatus, obtained from the inflamed rectal mucosa, and measured by enzyme-linked immunosorbent assay, was investigated in patients with ulcerative colitis. High serum antibody titers to the outer membrane protein of B. vulgatus were found in these patients. The specific outer membrane protein of B. vulgatus reactive to serum antibody was recognized as a 26-kDa protein. These findings indicate that B. vulgatus containing a 26-kDa protein in the outer membrane may be implicated in the pathogenesis of ulcerative colitis.
为阐明具核梭杆菌在溃疡性结肠炎发病机制中所起的作用,对溃疡性结肠炎患者进行了研究,通过酶联免疫吸附测定法检测从发炎的直肠黏膜获取的具核梭杆菌外膜蛋白的血清抗体滴度。这些患者中发现了针对具核梭杆菌外膜蛋白的高血清抗体滴度。与血清抗体反应的具核梭杆菌特异性外膜蛋白被识别为一种26 kDa的蛋白。这些发现表明,外膜含有26 kDa蛋白的具核梭杆菌可能与溃疡性结肠炎的发病机制有关。
