A Study to Evaluate The Role of Mucosal Microbiome in Recurrence of Clostridium Difficile Infection


About this study

The microbiome within the gut lumen has been found in prior studies to differ in individuals with C. difficile infection (CDI) in comparison to those without diarrhea. The microbiome associated with the mucosal surface on the colon has been noted to differ from that of the lumen in other clinical scenarios, although this has not been studied in depth in patients with CDI. The goal of this research is to characterize the mucosal microbiome in patients with CDI after treatment to characterize this microbiome and determine the effect on recurrence of CDI.
