    The study compares atopic dermatitis patients from a polluted metropolitan area and a less polluted interior municipality in Brazil.

  • 2

    Overall bacterial diversity did not differ between municipalities or age groups among patients with atopic dermatitis.

  • 3

    Patients in the metropolitan area showed significantly higher relative abundance of Staphylococcus aureus compared to those in the interior.

  • 4

    Urban exposome exposure may promote S. aureus overgrowth in atopic dermatitis, indicating a need for further investigation.

  • 5

    The study highlights the potential impact of environmental factors on skin microbiome dysbiosis in atopic dermatitis.
