Microbial Signatures as a Predictive Tool in IBD - Pearls and Pitfalls

Studies of microbial signatures have improved our understanding of the role of dysbiosis in gut microbiota for the pathogenesis of inflammatory bowel disease (IBD). New technological advances such as next-generation sequencing facilitate investigations on large patient cohorts, but require methodological considerations regarding study design, sample processing, data analysis, and integration. Here, we summarize recent study approaches in microbial ecology with respect to IBD research and discuss crucial process steps for the production and integration of adequate data sets.
