Abstract:
The effect of antiseptics upon fungal growth inside human stratum corneum is poorly documented. Therefore the present study was undertaken to assess the anti-dermatophyte activity of a diluted povidone-iodine wash solution using the corneofungimetry bioassay. When compared to a non-medicated cleansing product, regular applications of the antimicrobial for two weeks significantly abated the fungal invasiveness inside human stratum corneum. The present findings are most likely relevant for the clinical practice.
Insights
Povidone-iodine wash solutions can reduce fungal growth within human skin. This study found that regular use of this antiseptic significantly decreased fungal invasiveness in the stratum corneum over two weeks.
Area of Science:
- Mycology
- Dermatology
- Antimicrobial agents
Background:
- Fungal infections of the skin are common.
- The stratum corneum serves as a barrier against fungal invasion.
- The efficacy of antiseptics against fungi within the stratum corneum is not well-established.
Purpose of the Study:
- To evaluate the anti-dermatophyte activity of a diluted povidone-iodine wash.
- To investigate the effect of antiseptics on fungal growth within human stratum corneum.
Main Methods:
- Corneofungimetry bioassay was employed.
- Human stratum corneum samples were used.
- A diluted povidone-iodine wash was tested against fungal invasiveness.
Main Results:
- Regular application of the povidone-iodine wash for two weeks significantly reduced fungal invasiveness.
- The antimicrobial agent was more effective than a non-medicated cleansing product.
- Fungal growth within the stratum corneum was abated by the antiseptic treatment.
Conclusions:
- Diluted povidone-iodine wash demonstrates significant anti-dermatophyte activity.
- The findings suggest clinical relevance for managing fungal skin infections.
- Antiseptic use can effectively control fungal invasiveness in the stratum corneum.
