Primary Outcome Measures

Name	Time	Method
Correlation of Microbiome to Disease via Relative Abundance Found in Microbiome Sequencing	One year	Relative abundance of bacterial classes within taxonomic phyla and, more broadly, within their domain will be analyzed by sequencing the gut microbiome. These data will then be categorized among specific gastrointestinal disease types.

Secondary Outcome Measures

Name	Time	Method
Validation of Sequencing Methods	One year	To validate the methods used to sequence samples
