Signature 1
Source: Fig4A and B
Description: A, Differential abundance at genus level between hidradenitis suppurativa (HS) lesional skin and healthy controls. Note significantly higher relative abundance of Propionibacterium in healthy controls and significantly higher relative abundance of Porphyromonas and Peptoniphilus. B, Differential abundance at species level between HS lesional skin and healthy controls. Note higher relative abundance of Propionibacterium acnes in healthy controls than in lesional samples.
Abundance in Group 1: increased abundance in Hidradenitis suppurativa patients

B, Differential abundance at species level between HS lesional skin and healthy controls. Note higher relative abundance of Propionibacterium acnes in healthy controls than in lesional samples.
