Dermatophytes are one of the most common fungal agents causing superficial skin infections. The prevalence of these infections varies from place to place and is more commonly associated with poor socioeconomic status.
AIMS AND OBJECTIVESThe study aims to know prevalence of dermatophytosis and its distribution patterns among clinical specimens in and around Mahabubnagar.
MATERIALS AND METHODSSkin, hair and nail samples were collected from all the clinically suspected cases attending the Dermatology OPD from Aug 2013 -July 2014. Samples were examined microscopically under KOH mount. Culture was done on Sabouraud dextrose agar with antibiotics and Dermatophytes test medium and isolates were identified based on the cultural, microscopic and biochemical characteristics.
RESULTSOut of 88 specimens obtained, 58 (65.9%) were KOH positive and 30 (34%) were KOH negative. Culture positivity was seen in 59 (67%) samples. Tinea corporis was the most common clinical presentation 32 (36%) followed by Tinea cruris 20 (22.7%). Trichophyton mentagrophytes was the most common species isolated 41 (69.5%) followed by Trichophyton rubrum 9 (15.25%).
CONCLUSIONTrichophyton mentagrophytes was identified as the principal aetiological agent in our hospital, predominately presenting with clinical presentation of Tinea corporis.
