Antigonococcal effects of vaginal tampons

Area of Science:

• Microbiology
• Gynecology
• Toxicology

Background:

• Vaginal tampons are widely used feminine hygiene products.
• Neisseria gonorrhoeae is a significant cause of sexually transmitted infections.
• The potential antibacterial effects of tampons on vaginal pathogens are not fully understood.

Purpose of the Study:

• To investigate the in-vitro and in-vivo antibacterial effects of different vaginal tampon brands against Neisseria gonorrhoeae.
• To compare the sensitivity of gonococcal strains from various infection types to tampon antibacterial activity.
• To evaluate the potential of tampon materials to influence vaginal pathogens.

Main Methods:

• Testing 46 strains of Neisseria gonorrhoeae against various vaginal tampon brands in-vitro.
• Assessing the sensitivity of gonococcal strains from disseminated infections, uncomplicated genital infections, and pelvic inflammatory disease.
• Evaluating tampon efficacy in-vivo using subcutaneous chambers in mice infected with gonococcal infections.

Main Results:

• Significant variations in anti-gonococcal effects were observed among different tampon brands (p < 0.0001).
• Gonococcal strains from disseminated infections were more sensitive to tampons than those from uncomplicated infections; strains from PID were moderately sensitive.
• Tampons effective in-vitro were generally effective in-vivo; Rely tampon extracts showed no in-vitro effect but induced antibacterial activity in-vivo.

Conclusions:

• Tampon brands exhibit differential antibacterial properties against Neisseria gonorrhoeae.
• Infection severity influences gonococcal strain sensitivity to tampon effects.
• Both in-vitro and in-vivo testing are crucial for understanding tampon's antibacterial mechanisms and their impact on vaginal health.
