Environmental and Industrial Fungi
|
-
Certain tests might include common environmental molds like Penicillium and Aspergillus niger (non-pathogenic strains) to assess the antifungal properties of materials like paints, coatings, or textiles, preventing spoilage or degradation.
|
|
Quality Control Strains
|
-
Typically, specific species of Candida and Aspergillus are recommended by organizations such as CLSI and EUCAST.
|
Preparation of Antifungal Agent
-
Select an appropriate solvent to prepare the stock solution of the antifungal agent.
-
Dilute the antibacterial agent twice continuously to prepare a series of concentration ranges.

Various formulations
|
|
Novel or Investigational Antifungal Compounds
|
-
Natural products: Extracts or purified compounds from plants, microorganisms, or other natural sources.
-
Synthetic compounds: Novel chemical entities designed and synthesized in laboratories.
-
Biologics: Antibodies, peptides, or other biological molecules with potential antifungal activity.
|
|
Antifungal Agents Incorporated into Materials
|
-
Coatings: Paints, varnishes, or other surface treatments.
-
Polymers: Plastics, textiles, or other polymeric materials.
-
Building materials: Drywall, wood products.
-
Reference standards: Known antifungal agents with established activity against the test fungi, are used to validate the test system and compare the activity of new compounds.
|
Performing the Antifungal Susceptibility Test
-
Broth Dilution: Add the fungal inoculum to a series of test tubes or microplate wells containing antifungal diluents.
-
Agar Dilution: Add the diluted antifungal agent to the molten agar medium and then pour it into a petri dish.
-
Disk Diffusion: Diffuse the standardized fungal suspension onto the agar plate, and place the paper plate impregnated with a known concentration of antifungal agent on the agar surface.
-
Gradient Diffusion (Etest): Place a plastic strip containing an antifungal gradient on an AGAR plate inoculated with fungi.
Incubation
Cultivate the test substances under appropriate conditions to ensure that the fungi grow without antifungal agents.
Reading and Interpretation of Results
-
After incubation, evaluate the growth of the fungi in the presence of different concentrations of antifungal agents.
-
MIC: The minimum concentration of the antifungal agent that inhibits the visible growth of fungi is judged as MIC.
-
Determine the minimum effective concentration (MEC): The lowest concentration at which mycelial growth is significantly hindered compared with the control.
-
Result interpretation.
-
Quality Control: Set up controls throughout the entire testing process to ensure the sterility of the culture medium and reagents, that is, the applicability of the operating process.
Deliverables
The definitive outputs of our antifungal activity testing furnish a thorough evaluation of a fungal isolate's responsiveness to a panel of antifungal agents. These results are delivered in a standardized, readily interpretable format, accompanied by detailed methodological descriptions and rigorous quality control metrics.

Antifungal Mechanism Assay
-
Determination of Lesion of Plasma Membrane
Scattergram analysis was performed on each sample to assess morphological changes and the percentage of PI-positive cells was determined by flow cytometry.
-
Determination of The Mitochondrial Membrane Potential (MMP)
1). Membrane potential kit.
2). The changes in MMP in fungi after antifungal treatment were analyzed by laser confocal microscopy and flow cytometry with fluorescent dyes.
-
Determination of Mitochondrial ATPase Activity
The mitochondrial ATPase activity in fungal cells is measured using a Micro-ATPase Assay Kit.
-
Determination of Endogenous ROS Production
Endogenous ROS levels in fungal cells are measured by a fluorometric assay using the fluorescent dye.
Turnaround Time
The typical timeframe for this service ranges from 3 to 6 weeks, depending on the complexity of the project, the number of isolates and antifungal agents, and the specific assays required. Project timelines will be clearly defined in the initial consultation and project proposal.
Case Studies
Case 1: Dose-response Assays of the Selected Molecules Against Candida albicans Biofilms (XTT Assay)
Sample: Compound was Provided by the client.
Fungus: (Provided by Creative Biolabs.)
The client provided two small molecule samples. We contracted for the dose-response assay to test the inhibitory effects on the Candida albicans biofilm formation. As shown in the figure, the molecule could inhibit biofilm formation.
