Colonization of AD skin by S aureus and correlation to disease severity. A, Measurement of gDNA absolute abundance of S aureus CFUs/cm2 from swabs of healthy control and AD nonlesional and lesional skin normalized to skin area. B, Spearman correlation between the local Eczema Area and Severity Index (EASI) score and S aureus CFUs/cm2 from swabs of AD lesional skin. Each dot represents a single swab and the bars represent means ± SEMs. A, Nonparametric unpaired Kruskal-Wallis analysis was used to determine statistical significance: *P < .05; **P < .01; ***P < .001; ****P < .0001.
