Abstract

Background: Superficial fungal infections are one among the most common fungal diseases in the world. Dermatophytosis is common in tropical countries like India and may reach epidemic proportions in areas with high rate of humidity and over population and poor hygienic conditions.
Material & Method: The present study was undertaken to isolate, identify and determine the antifungal susceptibility of various fungal agents causing mycoses among the patients attending the Dermatology outpatient (OP) Chettinad hospital and research institute. Clinical samples from 200 patients were subjected to KOH examination and culture isolation. Causative agents were identified by colony morphology, pigment production and by microscopic examination. Antifungal susceptibility testing was done by broth dilution detecting the minimum inhibitory concentration.
Result: In total of 200 specimens cultured 98 dermatophytes were isolated and 12 non dermatophytic fungus were isolated which includes 5 isolates of Candida albicans and 7 isolates of Candida non albicans. Trichophyton mentagrophyte was the predominant dermatophyte isolate found in 62 cases of dermatophytosis followed by T.rubrum 22. This study showed among 98 isolates of dermatophytes, lowest value of MIC sensitivity was recorded in terbinafine as 0.03μg/ml and highest value was recorded with fluconazole 32μg/ml.
Conclusion: It is concluded that causative fungal agent for cutaneous mycoses in addition to dermatophytes and non-dermatophytes fungi Candida species also play an important role. Terbinafine was found to be the most potent drug for treating dermatophytic infections.
