DERMATOPHYTOSIS IN MAN: SPECIES WISE INCIDENCE OF DERMATOPHYTES IN VARIOUS CLINICAL SAMPLES ISOLATED FROM PATIENTS.

Dr.Gadangi Indira

Abstract


Dermatophytes are fungi that can cause infections of the skin, hair, and nails due to their ability to utilize keratin. The organisms colonize the keratin tissues and inflammation is caused by host response to metabolic by-products. These infections are known as ringworm or tinea, in association with the infected body part. Occasionally the organisms do invade the subcutaneous tissues, resulting in kerion development. There are three genera ie, Trichophyton, Microsporum and Epidermophyton, that cause dermatophytosis in human beings but there are several species present in these genera. If a particular species is known in diagnosis, the targeting of disease is more accurate during treatment.  Hence the present study was conducted on 400 patients visiting the dermatology clinic of Dr. B.Ramesh from 2012-2014, to know the incidence of species in a particular clinical type of tinea infections. Therefore 400 clinical samples were collected from 400 patients who were suspected to be suffering from tinea infections. The most common infection of dermatophytosis is tinea corporis followed by tinea cruris.  The frequent isolate is Trichophyton rubrum followed by T. violaceum in tinea corporis and again T.rubrum followed by Microsporum gypseum.
