Design outcomes

Primary

MeasureTime frameDescription
Correlation of Microbiome to Disease via Relative Abundance Found in Microbiome SequencingOne yearRelative 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

MeasureTime frameDescription
Validation of Sequencing MethodsOne yearTo validate the methods used to sequence samples
