Welcome to the DFI Symbiotic Bacterial Strain Bank website!

  • Our biobank contains 1400+ sequenced isolates from healthy donors
  • You can browse our collection by searching taxonomy, BLASTing proteins of interest, or BLASTing 16S sequences to find closely related isolates
  • Individual bacterial isolates reported in DFI Symbiotic Strain Bank are available to the research community.

If you want to request strains:

  • For requests of ten isolates or fewer, please complete DFI Strain Request Form1 and Form2 . Staff members will contact you to confirm the shipping address, set up an MTA and coordinate delivery.
  • Requests for more than ten isolates are considered potential collaborative projects. Please direct these requests to Eric G. Pamer or Laurie E. Comstock for discussion.
