简要总结
The study is randomized, double-blinded and placebo-controlled with a duration of 24 weeks. Following randomization, healthy elderly are randomized into two groups receiving probiotics or placebo. Fecal samples are collected before and after the study. The samples are investigated for Clostridium difficile levels, changes in diversity of the gut microbiota as well changes in the fecal metabolome. The effects of the produced metabolites on mitochondrial activity will moreover be investigated using selected intestinal cell lines.
