Aims: Epidermophyton, Microsporum and Trichophyton are the genera of dermatophytes causing superficial mycoses. These infections are on rise due to increase in immunocompromised patients and favorable environmental conditions in countries like India. The present study was undertaken to identify dermatophytes causing superficial fungal infection by microscopy and culture techniques which helps in accurate diagnosis and appropriate treatment of cases. Methodology and results: Samples were collected from affected sites after cleaning the affected surface with 70% alcohol. All samples were microscopically examined for presence of hyphal structures by digesting in 10% to 40% KOH solution. All samples were inoculated into Sabouraud dextrose agar with chloramphenicol and Sabouraud dextrose agar with cycloheximide and chloramphenicol and incubated at room temperature for four weeks. Tease mount technique and slide culture technique were used for identification of dermatophytes. One hundred and ten samples from clinically suspected dermatophytoses which includes 77(70%) from male and 33(30%) from female patients were processed for identification of dermatophytes. Samples were subjected to microscopy and culture. In 61 samples (54.54%) fungal hyphae were seen by direct microscopic examination (KOH). Fifty six samples (50%) yielded dermatophyte growth in culture. Trichophyton rubrum was the predominant species isolated followed by T. violaceum and T. mentagrophytes. Conclusion, significance and impact of study: Accurate and rapid diagnosis of superficial fungal infection is essential for proper management of cases. Direct microscopy is very good method for routine diagnosis, however culture remains gold standard.

Clinical types of onychorpycosis, consist of distal subungual orychomycosis, white superficial onychomycosis, proximal subongual onychomycosis and candidal onychomycosis. White superficial onychomycosis aippears as white, sharply outlined areas on the surfaces of toenails. The fingernails are not affected. Trichophyton mentogrophytes, rarely Trichophyton rubrm, is the causa ive dermatophytes. The auther reports a case of white superficial onychomycosis of the fingernail caused by T. rubrm.

In order to increase the positive rate of cultre for dermatophyte infections of the nails, the authors devised the new file method. It is to perform the KOH mount arid culture with fine subungual hyperkeratotic debris obtained from the hyponycLium after grinding the nail plate from the surface to the bottom using various files, And we compared the result of this new method with that of conventional scraping and punch methods in 40 toenails and ]1 fingernails. The positive rate of culture for tinea unguium by three different methods was as follows: It was 52.5%(21 cases) through conventional scraping method, 70% (28 cases) through punch method and 80% (32 cases) through file method in the 40 toenai ls. lt was 18.2% (2 cases) through punch method, 27. 3% (3 sases) through scraping method and 54. 6%(6 cases) through file method in the 11'fingernails. In conclusion, the file method was found to be a more effective and successful method to detect the causative organisms of tinea unguium and was also easy to handle.

BACKGROUND: Dermatophytes are usually identified based on their characteristic morphologies and physiological tests. However, identification is often delayed and problematic for atypical isolates. Recently, random amplified polymorphic DNA(RAPD) analysis was successfully performed for the identification of dermatophyes. OBJECTIVE: This study was performed to identify clinical isolates which could not be identified previously. The causes of unidentification were analysed and the merits and demerits of RAPD analysis were evaluated. METHODS: Thirty-six clinical isolates and 14 standard strains were included in this study. Seven mycological studies were performed and RAPD analysis was done by using primer OPAO-15 (5'-GAAGGCTCCC-3'). RESULTS: Based on the results of 7 mycological tests, 28 strains were confirmed as follows: 24, T. rubrum; 2, T. mentagrophytes; 2, T. raubitschekii. Four were considered as atypical strains of T. rubrum, and another 4 as non-dermatophytic moulds. This results were confirmed by RAPD analysis. CONCLUSION: RAPD analysis was useful for the identification of dermatophytes, especially the atypical strains. However, non-dermatophytic mould could not be identified by RAPD analysis. RAPD analysis was considered as a supplementary method to the conventional mycological studies for the identification of dermatophytes.
