艰难梭菌感染(CDI)已成为最普遍和最昂贵的医院感染之一。尽管CDI的重要性,我们的知识,这种感染的发病机制仍然是初步的。虽然先前使用抗生素通常被认为是CDI的必要条件,但抗生素使宿主对C.困难没有很好的定义。在这篇综述中,我们将探讨什么是已知的土著微生物群如何与主机一致行动,以防止殖民和毒力的C。difficile以及抗生素给药如何扰乱宿主微生物群的稳态,导致CDI。
Clostridium difficile infection (CDI) has become one of the most prevalent and costly nosocomial infections. In spite of the importance of CDI, our knowledge of the pathogenesis of this infection is still rudimentary. Although previous use of antibiotics is generally considered to be the sine qua non of CDI, the mechanisms by which antibiotics render the host susceptible to C. difficile are not well defined. In this review we will explore what is known about how the indigenous microbiota acts in concert with the host to prevent colonization and virulence of C. difficile and how antibiotic administration disturbs host–microbiota homeostasis, leading to CDI.
