肠道是人体巨大的细菌库,健康状态下因其完善的微生态平衡、完整的肠粘膜屏障和成熟的免疫功能,这些细菌被有效地限制于肠道内,但在某些因素影响下,正常居住在肠道中的原籍菌可穿过相对完整的肠粘膜上皮进入组织,到达肠系膜淋巴结、器官和血流,可引起肠源性感染,肠道内细菌向肠外组织迁移这一现象称为细菌移位。大量临床研究证 The gut is a huge bacterial pool of the human body, which is effectively limited to the gut because of its well-balanced micro-ecological balance, intact gut mucosal barrier and mature immune function, but under certain conditions, the normal The bacteria that live in the intestine can pass through the relatively intact intestinal mucosal epithelium into the tissue to reach the mesenteric lymph nodes, organs and bloodstream, which can cause enterogenous infections. The phenomenon of intestinal bacteria migrating to parenchyma is called bacterial translocation Bit. A large number of clinical research certificate
