Background: Superficial mycoses of the glabrous skin are among the most prevalent of human infectious diseases. The etiological agents comprise dermatophytes and yeast infections. Superficial mycoses are believed to affect 20% to 25% of the world's population and the relative occurrence of the etiologic agents of these infections varies from country to country. The present study was aimed at detecting the prevalence of dermatophytosis infection and etiological agent in rural North Maharashtra.
Material & Methods: Clinical specimens like skin scrapping, infected hair and clipped nails were collected in small paper envelopes after cleaning the area with 70% alcohol. All specimens were subjected to direct microscopy for fungal elements in 10% / 20% (for nail) KOH and culture in Sabouraudís Dextrose Agar (SDA) with Chloramphenicol antibiotics and Dermatophyte Test Medium (DTM). All necessary methods were undertaken for microscopic morphology.
Results: Diagnosis confirmed by microscopic examination in 126 cases (67%), and the etiological agents were isolated in 102 cases (53.92%). Dermatophytes, P. versicolor and Candida albicans were the major etiological agents isolated. Tinea corporis accounted for 51.96% (72.34%) occurred in age > 20 years of age. The frequency of other clinical types was Pityriasis versicolor 28.44% followed by Candidiosis 11.76%. Trichophyton rubrum was responsible for 32% of all dermatophyte infections. Followed by P. versicolor (28.44%) , Trichophyton mentagrophytes (24.60%) and Candida species (11.76%).
Conclusion: Non - dermatophytic fungi, dermatophytes were emerging as important causes of superficial mycosis. Cultures along with direct microscopy using KOH preparation were important method of definitive diagnosis of fungal infections.
