1·Are Helicobacter species and enterotoxigenic Bacteroides fragilis involved in inflammatory bowel disease?

炎症性肠病是否与螺旋杆菌及肠产毒性脆弱拟杆菌感染有关?。

2·These data revealed that the chromosomal DNA probes of Bacteroides fragilis could detect the common clinical Bacteroides with high sensitivity and specificity.

结果表明脆弱类杆菌染色体DNA探针可检测临床上常见的类杆菌属厌氧菌，敏感性和特异性较高。

3·AIM: to examine the effect of endotoxin of prevotella intermedia and bacteroides fragilis on proliferation and ultrastructure of periodontal ligament cells in vitro.

目的：观察中间普氏菌和脆弱类杆菌的内毒素对人牙周膜细胞增殖和超微结构的影响。

4·By using SDS-PAGE technique the soluble protein antigen of anaerobic bacteroides fragilis were studied. The results show three kinds of protein zone among the strains species.

本文报告了采用SDS—PAGE垂直板电泳技术对脆弱类杆菌及相关菌株超声波粉碎的可溶性蛋白抗原进行了电泳谱分析。
