艰难梭菌是抗生素治疗后个体肠道感染和腹泻的主要原因。最近的研究已经开始阐明诱导孢子形成和萌发的机制,并确定了艰难梭菌毒素在疾病发病机制中的作用。在确定微生物组、特定共生细菌种类和宿主免疫在防御艰难梭菌感染中的作用方面也取得了令人兴奋的进展。本文将对艰难梭菌感染及其发病机制的最新发现和进展进行综述。治疗艰难梭菌感染和抗生素后疾病可能很困难。在这篇综述中,Abt, McKenney和Pamer展示了对孢子萌发,毒力以及与宿主和微生物群相互作用的见解如何有助于对抗这种病原体。
Clostridium difficile is a major cause of intestinal infection and diarrhoea in individuals following antibiotic treatment. Recent studies have begun to elucidate the mechanisms that induce spore formation and germination and have determined the roles of C. difficile toxins in disease pathogenesis. Exciting progress has also been made in defining the role of the microbiome, specific commensal bacterial species and host immunity in defence against infection with C. difficile. This Review will summarize the recent discoveries and developments in our understanding of C. difficile infection and pathogenesis. Treating infection with Clostridium difficile and post-antibiotic disease can be difficult. In this Review, Abt, McKenney and Pamer show how insights into spore germination, virulence and interactions with the host and microbiota can help to combat this pathogen.
