Aflatoxin-like compounds produced by dermatophytes
Mycopathologia
|February 28, 1975
Summary
Researchers detected aflatoxin-like compounds in six dermatophyte mycelia using thin-layer chromatography. These findings are crucial for understanding potential mycotoxin contamination in dermatophytes.
Area of Science:
- Mycology
- Analytical Chemistry
- Dermatology
Background:
- Dermatophytes are fungi that cause skin infections.
- Aflatoxins are toxic compounds produced by certain fungi.
- The presence of mycotoxins in dermatophytes is not well-studied.
Purpose of the Study:
- To investigate the presence of aflatoxin-like compounds in dermatophyte mycelia.
- To identify specific dermatophyte species that may produce these compounds.
Main Methods:
- Thin-layer chromatography was used to analyze chloroform extracts.
- Dermatophyte mycelia extracts were compared against a standard aflatoxin extract.
- Chromatographic properties (Rf values and color) were used for comparison.
Main Results:
- Aflatoxin-like compounds were detected in six out of 30 dermatophyte mycelia extracts.
- The identified compounds shared identical Rf values and color with standard aflatoxin.
- The positive dermatophyte species were Epidermophyton floccosum, Nannizzia fulva, Nannizzia persicolor, Arthroderma gloriae, Trichophyton concentricum, and Trichophyton Gallinae.
Conclusions:
- Certain dermatophyte species possess the capability to produce aflatoxin-like compounds.
- This finding highlights a potential source of mycotoxin contamination.
- Further research is needed to characterize these compounds and their implications.
