Genetic mechanisms governing sporulation initiation in Clostridioides difficile.

ABSTRACT: As an anaerobe, Clostridioides difficile relies on the formation of a dormant spore for survival outside of the mammalian host's gastrointestinal tract. The spore is recalcitrant to desiccation, numerous disinfectants, UV light, and antibiotics, permitting long-term survival against environmental insults and efficient transmission from host to host. Although the morphological stages of spore formation are similar between C. difficile and other well-studied endospore-forming bacteria, the C. difficile genome does not appear to encode many of the known, conserved regulatory factors that are necessary to initiate sporulation in other spore-forming bacteria. The absence of early sporulation-specific orthologs suggests that C. difficile has evolved to control sporulation initiation in response
