Dermatophytosis is defined as the fungal infection of the skin, hair and nails by a group of keratinophillic fungi known as dermatophytes.
This study is an attempt to find out various species of dermatophytes in clinically suspected cases of dermatophytosis.
One hundred samples were subjected to direct microscopy by potassium hydroxide wet mount (KOH) and isolation on culture with Sabourauds dextrose agar.
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.
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%).
皮肤癣菌病被定义为一组称为皮肤癣菌的嗜角质真菌对皮肤、毛发和指甲的真菌感染。
本研究旨在查明临床疑似皮肤癣菌病病例中的各种皮肤癣菌种类。
100份样本采用氢氧化钾湿片法（KOH）进行直接显微镜检查，并在沙氏葡萄糖琼脂培养基上进行培养分离。
在这些样本中，80份（80%）KOH检查呈阳性，20份（20%）KOH检查呈阴性。总体培养阳性率为68%。皮肤癣菌病在男性中更为常见，男女比例为4:1。
培养共分离出7个菌种。红色毛癣菌（66.17%）是最常见的分离菌种，其次是须癣毛癣菌（19.11%）、紫色毛癣菌（7.35%）、断发毛癣菌（2.94%），絮状表皮癣菌和石膏样小孢子菌各有1株分离菌（1.47%）。
