Support of Colonization Resistance of the Gut Microbiota With the Synbiotic Food Supplement Nagasin®

The aim of this randomized, controlled, double-blind, parallel, multicentric trial is to investigate wether the synbiotic food supplement Nagasin® can support the colonization resistance of the gut microbiota after disturbance by antimicrobial treatment. The main question is whether Nagasin® can prevent any increase in abundance of C.difficile within the first four weeks after antimicrobial treatment for a C. difficile infection. Participants will receive Nagasin® or the comparator as a food supplement during the first four weeks after antimicrobial treatment for a C. difficile episode.
