Comparison of Different Methods for the Analysis of Gut Microbiome Composition (COLLECT)
The Influence of Different Sample Collection and DNA Extraction Methods on the Bacterial Composition of the Gut of Healthy Subjects
The human gastrointestinal tract shelters a complex and dynamic population of microorganisms, the gut microbiota, which plays an important role in immune and metabolic homeostasis. In recent years several major diseases were linked with alterations in the gut microbiome composition.
There are known factors which can influence gut microbiata composition. For example diet is known to play a fundamental role in determining the composition of the intestinal microbiota over time. However, there are very few studies evaluating how collection and DNA isolation methods affect microbiome composition.

Collection of stool samples
大体时间：one week
|
Collection of 2 stool samples in one week using different conditions DNA extraction from all samples will be performed using QIAamp Power Fecal (Qiagen, N. V) and ZymoBIOMICS (Zymo Research, CA.) to assess how different commercially available stool sampling kits and fecal DNA extraction kits influence the apparent composition of the gut microbiome |
