Summary

This prospective observational study will evaluate the microbiological profile of secondary bacterial infection and nasal colonization in participants with scabies or atopic dermatitis. Bacteria isolated from impetiginized skin lesions and nasal swabs will be compared, and antimicrobial susceptibility patterns will be assessed. Healthy participants without an inflammatory skin disease or signs of infection will provide nasal swabs as a control group. Patients will be followed on days 7 and 14 to assess clinical response and related clinical measures.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Scabies group: dermatologist-confirmed scabies and an active impetiginized skin lesion. * Atopic dermatitis group: dermatologist-confirmed atopic dermatitis and an active impetiginized skin lesion. * Healthy control group: no inflammatory skin disease or clinical signs of infection. * Written informed consent (and appropriate parent/guardian permission when applicable). Exclusion Criteria: * Systemic or topical antibiotic use within the previous 14 days. * Active nasal infection or nasal symptoms. * History of nasal surgery or anatomic nasal deformity. TEST DRAFT NOTE: The source protocol contains wording that may conflict with inclusion of healthy controls; the final eligibility text must be reconciled with the ethics-approved protocol before release.
