Introduction:
Dermatophytosis is defined as the fungal infection of the skin, hair and nails by a group of keratinophillic fungi known as dermatophytes.
Aims And Objectives:
This study is an attempt to find out various species of dermatophytes in clinically suspected cases of dermatophytosis.
Materials And Methods:
One hundred samples were subjected to direct microscopy by potassium hydroxide wet mount (KOH) and isolation on culture with Sabourauds dextrose agar.
Results:
Out of these 80 (80%) samples were KOH positive while 20 (20%) were KOH negative. Overall culture positivity rate was 68%. Dermatophytosis was more common in males, the M:F ratio was 4:1.
Conclusion:
Total seven species were isolated on culture. Trichophyton rubrum (66.17%) was the commonest isolate followed by Trichophyton mentagrophytes (19.11%), Trichophyton violaceum (7.35%), Trichophyton tonsurans (2.94%) and one isolate each of Epidermophyton floccosum and Microsporum gypseum (1.47%).

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.

The papillary layer is made of loose, areolar connective tissue, which means the collagen...
