DISINFECTION OF AEROSOLIZED PATHOGENIC FUNGI ON LABORATORY SURFACES. I. TISSUE PHASE
Abstract:
The effect of several fungicides on laboratory surfaces contaminated with the tissue phase of aerosolized Blastomyces dermatitidis, Coccidioides immitis, Cryptococcus neoformans, and Histoplasma capsulatum was ascertained. A statistical analysis of the data shows the correlation between fungi, surfaces, time, and concentration of disinfectant. All fungicides were effective at established times and concentrations, and the type of contaminated surface affected the fungicidal efficacy. By interpolating plotted graphs, laboratory personnel may determine, with a given fungicide, the concentration and time required to disinfect instruments, pipettes, gloves, bench tops, and floors contaminated with a tissue phase of pathogenic fungi.
Insights
Fungicides effectively eliminate pathogenic fungi like Blastomyces dermatitidis on lab surfaces. Surface type impacts efficacy, but concentration and time can be adjusted for disinfection.
Area of Science:
- Mycology
- Infectious Diseases
- Laboratory Safety
Background:
- Pathogenic fungi pose risks in laboratory settings.
- Effective decontamination protocols are crucial for preventing fungal transmission.
Purpose of the Study:
- To evaluate the efficacy of various fungicides against common pathogenic fungi.
- To determine the influence of surface type on fungicidal activity.
- To provide guidance for laboratory disinfection procedures.
Main Methods:
- Testing multiple fungicides against the tissue phase of Blastomyces dermatitidis, Coccidioides immitis, Cryptococcus neoformans, and Histoplasma capsulatum.
- Statistical analysis correlating fungi, surfaces, time, and disinfectant concentration.
- Assessing efficacy on various laboratory surfaces.
Main Results:
- All tested fungicides demonstrated effectiveness at specified concentrations and times.
- The type of laboratory surface significantly influenced fungicidal efficacy.
- Data allowed for interpolation to determine optimal disinfection parameters.
Conclusions:
- Fungicides are effective for decontaminating laboratory surfaces from pathogenic fungi.
- Adjusting fungicide concentration and exposure time based on surface type is necessary for optimal disinfection.
- This study provides a framework for safe laboratory practices when handling pathogenic fungi.

Cleaning, Sterilization, and Disinfection
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
Methods of Sterilization I: Physical Methods
Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...
Methods of Sterilization II: Chemical Methods
Using chemical sterilization rather than heat to clean out equipment is recommended. It eradicates and removes all bacteria,...
Transmission-based Precautions II: Airborne and Protective Environment
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...
