Simple tape-stripping method for highly reliable and quantitative analysis of skin microbiome

Area of Science:

• Microbiology
• Dermatology
• Genomics

Background:

• The human skin microbiome is crucial for skin health and disease, but daily microbial changes and their link to skin homeostasis remain unclear.
• Conventional skin sampling methods present technical challenges, limiting the frequency and feasibility of longitudinal studies.
• Understanding dynamic skin microbial composition requires innovative, accessible sampling techniques.

Discussion:

• A novel, operator-independent tape-stripping method was developed for rapid (30-second) skin microbiome sampling.
• This method allows for multiple samples from the same site with high DNA yield consistency (within 13.5%) and sequencing reproducibility (Pearson's correlation coefficient of 0.98).
• Results from the tape-stripping method are comparable to conventional swabbing, validating its efficacy.

Key Insights:

• The developed tape-stripping technique offers a simple, stable, and highly reliable approach for quantitative skin microbiome analysis.
• It overcomes limitations of traditional methods, enabling increased sampling opportunities.
• This facilitates deeper investigation into the relationship between skin microbial dynamics and dermatological conditions.

Outlook:

• This method is poised to advance clinical research by improving the understanding of skin disease development and diagnosis.
• It supports more frequent, longitudinal studies of the skin microbiome.
• Future applications may include personalized diagnostics and therapeutic strategies targeting the skin microbiota.
