Abstract

 Background & Objective: Dermatophytic infections are commonly encountered problem and constitute more than 50 % of cases in dermatology outpatient departments. Dermatomycoses is seen all over the world both in urban and rural areas. Ahmedabad is a tropical area for the development of dermatomycoses. We found lot of cases post-monsoon due to favorable climatic condition of hot & humid atmosphere for the development of fungal infections. Last study carried out was by Shah & Amin et al in 1975. As there was no scientific data available since last 40 years, present study was carried out to see & compare changes in incidence, clinical presentation and etiological agents.
Material & Methods: 200 clinically suspected cases of dermatomycoses were examined and subjected to mycological study by KOH & culture on SDA with actidione and DTM.
Result & Interpretation: Tinea corporis was the commonest clinical presentation. Maximum incidence was seen in young adults & adolescents in age group of 11-40 years. Males were more affected compared to females. KOH examination & culture were positive in 75.5 % & 41.6 % of cases respectively. Trichophyton mentagrophyte (47.3 %) was commonest fungal isolate followed by Trichophyton rubrum (44.6 %). Trichophyton violaceum was isolated from cases of tinea capitis only. All culture positive isolates grow on both SDA & DTM. Appearance of growth was faster in DTM compared to SDA with actidione.

Keywords: Dermatomycoses, Trichophyton mentagrophyte, Trichophyton rubrum, SDA-Sabouraud’s Dextrose Agar, DTM-Dermatophyte Test Medium.
