The human skin microbiome exhibits topographical and temporal diversity, with distinct bacterial communities in different skin sites. A study analyzed 16S rRNA gene sequences from 20 skin sites of 10 healthy individuals, revealing that physiologically similar sites share similar bacterial communities. The complexity and stability of these communities depend on the specific skin site. The skin is a critical interface between the body and environment, hosting diverse microbial communities in distinct niches. Traditional culture-based methods are biased toward easily cultured species, but molecular approaches reveal greater diversity. Characterizing skin microbiota may provide insights into skin health and disease. Certain dermatological disorders occur at specific sites, and changes in hygiene or lifestyle can alter the microbiome. Understanding microbial communities could help in managing skin diseases and antibiotic resistance. The study characterized the microbiome of 20 skin sites, identifying dominant bacterial phyla and genera. The microbiome varied across skin types, with sebaceous sites dominated by Propionibacteria and Staphylococci, moist sites by Corynebacteria, and dry sites by β-Proteobacteria and Flavobacteriales. The study also assessed interpersonal and intrapersonal variation, finding that some sites were more similar to themselves than others. Temporal variation was observed, with some sites showing stability over time. The study contributes to understanding the human microbiome and its role in health and disease, providing a reference for future research. The findings highlight the importance of microbial communities in skin health and disease, and suggest that maintaining a balanced microbiome may be key to preventing skin disorders.The human skin microbiome exhibits topographical and temporal diversity, with distinct bacterial communities in different skin sites.
