    摘要:

    肠源性白念珠菌感染是指肠道内定植的白念珠菌在一定条件下发生易位,突破肠道,造成组织感染,甚至引发侵袭性白念珠菌感染。肠道黏膜作为念珠菌第一接触位点,是抵抗白念珠菌定植或侵入的第一道防线,常通过物理屏障和激活宿主免疫抑制感染。作为另一种防御机制,肠道内微生物群则通过调节pH, 分泌抗菌肽和竞争黏附点共同抵抗白念珠菌侵袭感染。本综述总结肠道黏膜、肠道免疫和微生物群这三个关键因素在肠源性白念珠菌感染中的作用, 为肠道定植引发侵袭性白念珠菌病的科学研究提供新思路。

    Abstract:

    Enterogenic Candida albicans (C. albicans) infection refers to the translocation of intestinal colonized C. albicans under certain conditions, breaking through the intestinal tract, causing tissue infection or even invasive C. albicans infection. As the first contact point of Candida, the intestinal mucosa is the first line defending colonization or invasion of C. albicans, often inhibiting infection by physical barrier and activating host immunity. As another defense mechanism, the intestinal microbiota jointly resists the invasive infection of C. albican through regulating pH, secreting antimicrobial peptides, and competing for adhesion points. This review summarizes the roles of three key factors, namely intestinal mucosa, intestinal immunity and microbiota, in enterogenic C. albicans infection, providing new ideas for scientific research on invasive candidiasis caused by intestinal colonization.
