Culture Visit (Day 7 +/- 4) Eligible subjects will return for a culture visit within approximately a week of their screening visit. During this visit we will take four (4) culture swabs from the subject's non-lesional (no AD) skin on their upper arms. These culture swabs will be placed in tryptic soy broth (TSB) until processed in the lab, where they will be used to grow the subject's antimicrobial peptide-producing Staph species to use for the autologous microbiome transplant. Subjects will also receive a bar of Dove moisturizing soap, which they will be instructed to use whenever they shower until after the follow-up visit is complete. Subjects with a positive S. aureus nasal culture at the screening visit (Visit 1) will also receive a tube of mupirocin ointment. They will be instructed on the application of mupirocin to the anterior nares bilaterally twice a day starting 5 days prior to their treatment visit. The total visit will take approximately 10 minutes.
