Abstract
Germination by Clostridioides difficile spores is an essential step in pathogenesis. Spores are metabolically dormant forms of bacteria that resist severe conditions. Work over the last 10 years has elucidated that C. difficile spores germinate thorough a novel pathway. This review summarizes our understanding of C. difficile spore germination and the factors involved in germinant recognition, cortex degradation and DPA release.
摘要
艰难梭菌孢子的萌发是其发病机制中的一个重要步骤。孢子是细菌的一种代谢休眠形式，可以抵抗恶劣条件。过去 10 年来的研究工作阐明了艰难梭菌孢子通过一种新途径进行萌发。本文综述了我们对艰难梭菌孢子萌发的理解，以及涉及发芽剂识别、皮层降解和 DPA 释放的因素。
