Summary

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.

Detailed description

An observational clinical study with 28 healthy subjects is planned to assess how different commercially available stool sampling kits and fecal DNA extraction kits influence the apparent composition of the gut microbiome. Participants will be instructed to collect stool samples at two time points separated by one week using six different methods (naïve and Zymo DNA/RNA Shield kit on dry ice as well as OMNIgene GUT, RNALater, 95% EtOH, Zymo DNA/RNA Shield at room temperature). DNA extraction from all samples will be performed using QIAamp Power Fecal (Qiagen, N. V) and ZymoBIOMICS (Zymo Research, CA.).
