Incidence and identification of dermatophytes associated with patients of Tinea corporis in a tertiary care hospital
Journal Title: INTERNATIONAL JOURNAL OF RECENT TRENDS IN SCIENCE AND TECHNOLOGY - Year 2017, Vol 22, Issue 2
Abstract
Background: Dermatophytosis is the most important group of superficial fungal infections caused by dermatophytes. Tinea corporis is ringworm of glabrous skin (non hairy skin) of body. The identification of the causative agent is necessary which provides information on the risk of spread to other members. Clinical lesions caused by the dermatophyte causing agents are highly variable and closely resemble other skin diseases making laboratory diagnosis and confirmation necessary. Material and Methods: The samples were examined for dermatophyte hyphae, arthroconidia by using 10% KOH. Specimens were then cultured on Sabouraud’s Dextrose Agar with antibiotics and growth on obverse and reverse was noted. Colony was further observed microscopically with lactophenol cotton blue mount. Results: T. rubrumand T. Mentagrophytes were the dermatophyte species isolated from 187 patients. T. rubrum was isolated from 136 patients (72.7%) and T. mentagrophytes from 51 (27.3%).All 187 cases (100%) were positive by both microscopy and culture. Discussion: Dermatophyte infections are very common in this region where hot and humid climate in association with poor hygienic conditions play an important role in the growth of these fungi. Tinea corporis was the commonest clinical type. Trichophyton species forms the commonest aetiological agent of dermatophytosis and T. rubrum was the commonest isolate.
