Who can join

Adults 18 to 40, female only, with Diet Modification or Microbial Colonization. Patients with the condition only — healthy volunteers not accepted.

Sponsor's own description

Samples will be collected to determine human genetic variation, fecal and oral microbial communities, and metabolome products. Several evolutionary and ecological diversity metrics will be distilled to test: a) if microbiome variation within each ethnicity is less than that between ethnicities; b) if microbiome variation is finely structured according to genetic relatedness; and c) if dietary variation impacts human genome x microbiome associations.
