Staphylococcus aureus colonization is common in tampons used by healthy women, with applicator-free tampons showing higher contamination rates. The study identified the toxic shock syndrome toxin 1 (TSST-1) producing S. aureus clone in tampons, highlighting hygiene importance.
Area of Science:
- Microbiology
- Infectious Diseases
Background:
- Menstrual toxic shock syndrome (MTSS) is a severe illness linked to TSST-1 producing Staphylococcus aureus.
- Previous research focused on vaginal swabbing, not tampon colonization, for S. aureus prevalence.
Purpose of the Study:
- To determine the prevalence of S. aureus colonization in tampons from healthy women.
- To identify S. aureus strains, including TSST-1 producers, and associated risk factors.
Main Methods:
- Analysis of tampons from 737 healthy women for S. aureus presence and toxin production.
- Genotyping of S. aureus strains to determine clonal complexes (CCs).
Main Results:
- 27% of tampons were colonized by S. aureus; 4% by TSST-1 producing strains.
- Higher S. aureus prevalence in applicator-free tampons (32%) and with intrauterine device use (34%).
- CC30 agr3, a TSST-1 producing clone responsible for MTSS, was identified in tampons.
Conclusions:
- Tampons show a high prevalence of S. aureus, including the MTSS-associated clone.
- Applicator-free tampons and IUD use are associated with increased S. aureus colonization.
- Hand hygiene during tampon use is crucial to reduce contamination risk.
