Atopic dermatitis (AD) is a relapsing, chronic, and inflammatory skin disorder. Its causes remain unclear. Here, we reported the first proteome study of the bacterial community in AD patients. Bacterial community in 7 patients and 1 healthy control using bottom-up proteomics were examined starting with in-solution digestion followed by purification steps with subsequent analysis using LC-MS/MS and ended with data processing and bioinformatic analysis. Overall, great bacterial changes between patient samples and healthy one were noticed with the presence of Staphylococcus aureus, Aeromonas hydrophila, and Shewanella species, and others that were present uniquely in patient samples suggesting their role in AD. Additionally, detection of some important proteins that trigger bacterial pathogenesis and the immune system such as enolase, glyceraldehyde-3-phosphate, Chaperone proteins DnaK and HtpG beside protein pathways needed for bacterial growth and pathogenesis like chaperones and folding catalysts; and Energy metabolism. These new findings of the microbiome and detected proteins could start a new era of proteomics to study the bacterial community as a whole and detect the way it interacts with each other and with the host.This paper would represent a reference work for investigations on microbiota that present on AD, from both a microbiological and a functional proteomic point of view. We focused on analysisng bacteria community and proteins produced and its role in the disease, highlighting some functional characteristics of certain proteins and discussing its potential role in AD.
