INTRODUCTION: @entity281 are commonly encountered a problem and constitute more than 50% of cases in dermatology outpatient departments. Diagnosis of these infections requires the proper use of laboratory methods. OBJECTIVES: This study was conducted to know the etiology of @entity4013 in @entity1 attending Tertiary Care Level Hospital in South India and to compare the efficacy of Sabouraud's dextrose agar (SDA) with @entity1880 and dermatophyte test medium (DTM) in isolating and identifying dermatophytes. MATERIALS AND METHODS: A total of 110 samples which included 101 skin samples and 9 hair samples from clinically suspected @entity4013 were collected. Direct microscopy by @entity3071 and culture on SDA with @entity1880 and DTM were done. RESULTS: Of 110 samples collected, 58.18% were @entity3071 positive for fungal filaments and 56.36% were culture positive for dermatophytes. More number of cases were observed between age groups of 21-40 years. Males were more affected compared to females. @entity4013 was the common clinical presentation observed (40%). @entity12734 (58.06%) was the predominant isolate recovered in all clinical presentations but @entity12734 violaceum was the most common isolate in @entity3100 . All culture positives were grown on both SDA with @entity1880 and DTM. Appearance of growth was earlier on DTM that is, within 10 days compared to SDA with @entity1880 where growth started appearing only after 10 days. This is statistically significant P < 0.0001 (  (2) = 71.6). Species level identification on primary isolation was possible when grown on SDA with @entity1880 and it was not possible with the growth on DTM on primary isolation. CONCLUSION: DTM is a good screening medium in laboratory diagnosis of @entity4013 when compared to SDA with @entity1880 . But DTM is inferior to SDA with @entity1880 in identification of dermatophyte species.
