Arm && Interventions

Group	Intervention	Description
Psoriasis patients	No Intervention	Patients who have been diagnosed with Psoriasis

Primary Outcome Measures

Name	Time	Method
Correlation of Microbiome to Psoriasis via Relative Abundance Found in Microbiome Sequencing	1 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 correlated with specific Psoriasis types

Secondary Outcome Measures

Name	Time	Method
Validation of Sequencing Methods	1 year	To validate the methods used to sequence samples
