[T. faviforme sensitivity to the disinfecting action of various preparations]
Abstract:
Tested was the resistance of T. faviforme in pathological material to various disinfection agents. It was demonstrated that 1 per cent vofasteril, and 1.62 per cent perfumaric acid together with 1 per cent lauril sulphate and 5 per cent fessiasept kill the fungus at a 10 min. exposure. Perfumaric acid (1.62%), veraform (5%), fessiasept (3%) destroy T. faviforme for 15 to 20 min, and 0.6% vofasteril and 7-10% Cusulphate produce a fungicidal effect for 30 to 45 min. Fungicidal effects are produced with the use of veraform and vofasteril at the rate of 0.51/m2 of the disinfection solution. Aerosols, obtained by a method using no apparatus, employing 40 cm3 formalin, 20 cm3 water, and 30 g potassium permangante produce a fungicidal effect at a 20 h. exposure.
Insights
Various disinfectants effectively kill the fungus T. faviforme. Concentrations and exposure times vary, with some agents like Vofasteril and perfumaric acid showing rapid fungicidal action against this pathogen.
Area of Science:
- Mycology
- Antimicrobial Efficacy
Context:
- Fungal infections caused by T. faviforme pose a significant challenge in various settings.
- Assessing the efficacy of common disinfectants against pathogenic fungi is crucial for infection control.
Purpose:
- To evaluate the fungicidal activity of different chemical agents against T. faviforme in pathological samples.
- To determine the optimal concentrations and exposure durations for effective disinfection.
Summary:
- 1% Vofasteril, 1.62% perfumaric acid with 1% lauril sulphate and 5% fessiasept demonstrated rapid fungicidal effects within 10 minutes.
- Other agents like perfumaric acid (1.62%), veraform (5%), fessiasept (3%), 0.6% vofasteril, and 7-10% copper sulphate exhibited fungicidal properties at longer exposure times (15-45 minutes).
- Aerosolized formalin, water, and potassium permanganate also showed fungicidal effects after a 20-hour exposure.
Impact:
- Provides essential data for selecting appropriate disinfectants to control T. faviforme.
- Informs public health and clinical practices for preventing and treating fungal contamination.
- Highlights the variability in disinfectant efficacy based on chemical composition and application method.
