Abstract

BACKGROUND

Dermatophytosis is a disease of major public health problem around the globe causing a considerable morbidity.

OBJECTIVE

To study the prevalence of dermatophytosis and the spectrum of fungi implicated in causing the infection.

METHODS

Nail, skin, and scalp scrapings were collected from 318 patients and were used for microscopy and culture study. Fungal pathogens were identified by studying the macroscopic and microscopic characteristics of their colonies.

RESULT

Tinea capitis was the predominant clinical manifestation consisting of 48.1% of the cases. Among 153 patients with tinea capitis, 73.2% were in the age group of 1-14 years. Of 318 study participants, 213 (67.98%) were found to be positive for dermatophytosis microbiologically. Out of 164 fungal isolates, 86 were dermatophytes and 78 were non-dermatophyte fungi. Among 86 dermatophytes, . represented 38.4% of dermatophyte isolates and 89.7% of the isolates were recovered from tinea capitis. Of 76 non-dermatophyte molds, s spp., spp. were the most common isolates, respectively.

CONCLUSIONS

Failure to detect or isolate fungal pathogens in a large number of clinical samples revealed the limitation of clinical diagnosis in differentiating dermatophytosis from other skin infections demonstrating that clinical diagnosis should be coupled with laboratory methods. Recovery of large number of non-dermatophyte fungi along with dermatophytes in our study showed that non-dermatophyte fungi are emerging as important causes of dermatophytosis, warranting the implementation of intensive epidemiological studies of dermatophytosis across the country.

摘要

背景

皮肤癣菌病是全球主要的公共卫生问题,会导致相当高的发病率。

目的

研究皮肤癣菌病的患病率以及引起感染的真菌种类。

方法

从318名患者处采集指甲、皮肤和头皮刮屑,用于显微镜检查和培养研究。通过研究真菌菌落的宏观和微观特征来鉴定真菌病原体。

结果

头癣是主要的临床表现,占病例的48.1%。在153名头癣患者中,73.2%在年龄组为1 - 14岁。在318名研究参与者中,213名(67.98%)在微生物学上被发现患有皮肤癣菌病。在164株真菌分离物中,86株是皮肤癣菌,78株是非皮肤癣菌真菌。在86株皮肤癣菌中, 占皮肤癣菌分离物的38.4%,89.7%的分离物从头皮癣中分离得到。在76株非皮肤癣菌霉菌中, 属、 属分别是最常见的分离物。

结论

在大量临床样本中未能检测或分离出真菌病原体,揭示了临床诊断在区分皮肤癣菌病与其他皮肤感染方面的局限性,表明临床诊断应与实验室方法相结合。在我们的研究中,大量非皮肤癣菌真菌与皮肤癣菌一起被分离出来,表明非皮肤癣菌真菌正在成为皮肤癣菌病的重要病因,这就需要在全国范围内开展深入的皮肤癣菌病流行病学研究。
