Abstract

This study examines the distribution and variation of skin microbiota across different body sites, ages and genders. We collected and analyzed bacterial samples from males and females aged 20- 60 from five body regions (mouth, nose, ear, underarms, and skin). Results revealed distinct microbial profiles: Micrococcus spp. were predominantly found in males, while Enterobacter spp. were more common in females. Notable age-related shifts included an increase in Corynebacterium and Streptococcus in older males and Citrobacter and Pseudomonas in older females. These findings highlight the influence of factors such as moisture, pH and nutrition on skin microbiota and emphasize the need for gender-specific considerations in microbiome research. Understanding these microbial distributions is crucial for insights into skin health and disease and may inform future therapeutic and cosmetic applications.
