Clinical and mycological features of onychomycosis show variation with time and place.
A study to analyze the morphological variants and mycological isolates of onychomycosis was carried out in 50 patients attending the dermatology out-patient departments at the Air Force Hospitals at Bangalore and at Jorhat. Nail clippings were subjected to direct microscopy and cultured on Sabouraud's Dextrose Agar.
The commonest age group affected (56%) was the 20-40 year age group. The fingernails alone were involved in 24 (48%) patients, the toenails alone in 15 (30%) patients, and both in 11 (22%) patients. Distal and lateral subungual onychomycosis was encountered in 41 (82%) patients, proximal superficial onychomycosis and total dystrophic onychomycosis in 3 each (6%), paronychia in 2 (4%) and superficial white onychomycosis in 1. Of the 59 samples cultured, dermatophytes were grown in 14 (23.7%), non-dermatophyte moulds (NDM) in 13 (22.0%), candida in 10 (16.8%) and no growth in 22 (37.2%) samples.
Among the dermatophytes, Trichophyton rubrum, and among the NDM, Aspergillus spp., were the commonest isolates.
甲癣的临床和真菌学特征随时间和地点而变化。
对班加罗尔和乔哈特空军医院皮肤科门诊的50例患者进行了一项分析甲癣形态学变异和真菌分离株的研究。将指甲剪进行直接显微镜检查，并在沙氏葡萄糖琼脂上培养。
受影响最常见的年龄组（56%）为20至40岁年龄组。仅手指甲受累的患者有24例（48%），仅脚趾甲受累的患者有15例（30%），两者均受累的患者有11例（22%）。41例（82%）患者出现远端和侧位甲下甲癣，近端浅表甲癣和全营养不良性甲癣各3例（6%），甲沟炎2例（4%），浅表白色甲癣1例。在培养的59个样本中，14个（23.7%）培养出皮肤癣菌，13个（22.0%）培养出非皮肤癣菌霉菌（NDM），10个（16.8%）培养出念珠菌，22个（37.2%）样本无生长。
在皮肤癣菌中，红色毛癣菌最常见，在NDM中，曲霉属最常见。
