Background. Dermatomycoses are not diseases requiring compulsory notifications; rather they cause cosmetic defacements. Indian subcontinent with a varied topography is favorable for various fungal infections. Objective. To look for the epidemiological and mycological profile of superficial mycoses in North India. Methods. Three hundred and fifty-one clinical samples of skin, hair, and nail were examined to find the fungal etiology of the dermatomycoses. Results. Dermatomycoses were seen in 215/351 (61.2%) of cases. Most common isolates obtained were nondermatophyte molds (NDMs) (36.1%), followed by dermatophytes (13.8%) and yeasts (8.6%). Aspergillus niger (9%) was the most common mold. Trichophyton rubrum (4.6%) was the most common dermatophyte isolated, while amongst the yeasts Non-albicans Candida (NAC) species were more common (6%). Many other NDMs like Syncephalastrum spp., Cunninghamella spp., Rhodotorula spp., A. terreus, Scytalidium spp. and Scopulariopsis spp. were also isolated. Conclusion. Our study reflects an increasing role of NDMs (thought to be normal laboratory or environmental contaminants) as a causative agent of dermatomycoses, replacing the dermatophytes. Clinician's awareness of the demographic profile of the population involved along with more studies on dermatomycoses can help in understanding the etiological profile in area, leading to prevention of disease occurrence and cosmetic disfigurement.
背景。皮肤真菌病并非需要强制报告的疾病;相反,它们会导致外观受损。地形多样的印度次大陆有利于各种真菌感染。目的。探寻印度北部浅表真菌病的流行病学和真菌学特征。方法。对351份皮肤、毛发和指甲的临床样本进行检查,以确定皮肤真菌病的真菌病因。结果。在351例病例中有215例(61.2%)出现皮肤真菌病。分离出的最常见菌株是非皮肤癣菌霉菌(NDMs)(36.1%),其次是皮肤癣菌(13.8%)和酵母菌(8.6%)。黑曲霉(9%)是最常见的霉菌。红色毛癣菌(4.6%)是分离出的最常见皮肤癣菌,而在酵母菌中,非白色念珠菌(NAC)种类更为常见(6%)。还分离出了许多其他NDMs,如共头霉属、小克银汉霉属、红酵母属、土曲霉、帚霉属和拟青霉属。结论。我们的研究反映出NDMs(曾被认为是正常实验室或环境污染物)作为皮肤真菌病病原体的作用日益增加,正在取代皮肤癣菌。临床医生对相关人群人口统计学特征的认识以及对皮肤真菌病的更多研究有助于了解该地区的病因特征,从而预防疾病发生和外观受损。
