Genetic diversity of S. aureus strains associated with AE flares. The distribution of the clonal complex (CC) structure of S. aureus isolates from AE patients (n = 9) and nasal carriage control participants (n = 18). In the single patient in whom co-colonization (patient 8) was observed, both CCs identified in the colonizing population are represented. Skin and extra-nasal carriage was found in four AE patients (see Supplementary Table S2), three of whom were carrying CC1 isolates at both sites; one was carrying CC121 isolates (see Supplementary Table S3). Skin-only carriage isolates in AE patients (n = 5) were distributed across clonal backgrounds (see Supplementary Tables S2 and S3). AE, atopic eczema.
