[The bacterial flora of preputial space].
Summary
The bacterial flora in the preputial space varies with age and whether the glans penis is covered. A covered glans harbors denser microbial populations, including gram-negative anaerobes.
Area of Science:
- Microbiology
- Human Anatomy
Background:
- The preputial space harbors a complex bacterial flora.
- Understanding this microbiome is crucial for male health.
Purpose of the Study:
- To characterize the bacterial flora of the preputial space in healthy males across different age groups.
- To investigate the influence of glans coverage on microbial distribution.
Main Methods:
- Smears and cultures were performed on the glans penis, sulcus coronarius, and prepuce.
- Samples were collected from 210 healthy males across three age categories.
- Data were analyzed based on age and glans coverage (covered vs. uncovered).
Main Results:
- Significant differences in bacterial distribution were observed with age.
- Uncovered glans showed gram-positive saprophytic bacteria, particularly in sebaceous gland-rich areas.
- Covered glans exhibited increased microbial density, with prevalent gram-negative anaerobes (e.g., Bacteroides melaninogenicus), enterococci, enterobacteria, and staphylococci.
Conclusions:
- Age and glans coverage are key factors influencing the preputial microbiome.
- The composition of the bacterial flora shifts with these parameters, impacting the local environment.
