At baseline, bacterial community richness and SDI at both lesional and nonlesional sites in both treatment groups were lower than control skin, to similar extents. A. Following treatment, the mean OTU numbers (representing community richness) increased at lesional sites, becoming similar to control skin in both treatment groups. B. After treatment, there were no changes in the mean Shannon diversity index in control or nonlesional skin but diversity for lesional skin for both treatment groups normalized, resembling control skin. Symbols: L, lesion; NL, uninvolved site; C, control site.
