Lipids of dermatophytes

G K Khuller, A Chopra, V S Bansal

    Lipids
    |January 1, 1981
    PubMed
    Summary

    Lipid profiles of dermatophytes Epidermophyton floccosum, Microsporum cookie, and Trichophyton mentagrophytes change with age. Phosphatide levels decrease, while fatty acid composition shifts, impacting fungal growth and lipid metabolism.

    Area of Science:

    • Mycology
    • Biochemistry
    • Dermatophyte research

    Background:

    • Dermatophytes are fungi causing skin infections.
    • Understanding their lipid composition is crucial for antifungal strategies.
    • Growth phases significantly influence fungal metabolism.

    Purpose of the Study:

    • To analyze phosphatide and fatty acid content in dermatophytes during different growth stages.
    • To investigate age-related changes in lipid profiles of Epidermophyton floccosum, Microsporum cookie, and Trichophyton mentagrophytes.

    Main Methods:

    • Analysis of total phosphatides and constituent phospholipids.
    • Quantification of short-chain and total fatty acids.
    • Determination of saturated to unsaturated fatty acid ratios across growth phases.

    Main Results:

    • Total phosphatide content decreased with fungal age.
    • Short-chain fatty acids increased with age in E. floccosum.
    • Saturated to unsaturated fatty acid ratios varied significantly with age across species.

    Conclusions:

    • Fungal age profoundly impacts lipid metabolism in dermatophytes.
    • Species-specific alterations in fatty acid profiles occur during growth.
    • Lipid composition changes may influence fungal physiology and susceptibility.
