The pathogenesis of dermatophyte infections in human skin sections
1Department of Microbiology, Rappaport Faculty of Medicine, Technion, Institute of Technology, PO Box 9649, Haifa 31096, Israel.
Aim:
A novel ex vivo model for the study of adherence and invasion of dermatophytes to the stratum corneum was developed.
Materials And Methods:
A skin of full epidermis thickness was infected by spores of Trichophyton mentagrophytes and examined after various periods of time by scanning and transmission electron microscopy.
Results:
After 12 h of inoculation a tenacious adherence between the spores and the stratum corneum was observed. There was a time dependent increase in the number of spores adhered to this surface. By 24 h, germination had commenced. The initial growth of germ tubes occurred extracellularly to the corneocytes. Three days after inoculation, the most prominent feature was proliferation of fungal hyphae and penetration of mycelium through the outer keratinocyte layer which is followed by invasion of the outer stratum corneum.
Conclusion:
The model introduced in the present study may contribute to a better understanding of the nature of the interaction between dermatophytes and skin cells in dermatophytosis process.

Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
