    Area of Science:

    • Microbiology
    • Human Microbiome Studies

    Background:

    • The skin microbiome plays a crucial role in human health.
    • Understanding variations in skin flora is essential for dermatological research.

    Purpose of the Study:

    • To quantitatively assess aerobic skin flora across seven body sites.
    • To investigate temporal changes and sex-based differences in skin microbial communities over three months.

    Main Methods:

    • Quantitative analysis of aerobic bacterial flora.
    • Sampling of seven distinct skin sites in 16 healthy volunteers.
    • Repetition of sampling after a three-month interval.

    Main Results:

    • Significant differences in total aerobic bacterial densities were observed across skin sites.

  • Male volunteers exhibited higher bacterial loads and a greater diversity of biotypes compared to females.
  • Qualitative variations in the skin's aerobic flora were detectable over the study period.

    • Conclusions:

    • Skin aerobic flora exhibit site-specific and sex-specific quantitative variations.
    • Temporal stability of the skin microbiome is influenced by factors such as sex.
    • Further research is warranted to explore the functional implications of these microbial differences.
