The effects of Lactobacillus johnsonii La1 (LC1) on Helicobacter pylori colonization in the stomach were investigated. H. pylori colonization and gastritis in LC1-inoculated Mongolian gerbils were significantly less intense than those in the control animals. LC1 culture supernatant (>10-kDa fraction) inhibited H. pylori motility and induced bacterial aggregation in human gastric epithelial cells, suggesting the potential of clinical use of LC1 product.
研究了约氏乳杆菌La1(LC1)对胃中幽门螺杆菌定植的影响。接种LC1的蒙古沙鼠中幽门螺杆菌的定植和胃炎程度明显低于对照动物。LC1培养上清液(>10 kDa部分)抑制幽门螺杆菌的运动,并在人胃上皮细胞中诱导细菌聚集,提示LC1产品具有临床应用潜力。
