“…We have not reported any case of extensive tinea due to T. violaceum though epidemics/outbreaks have been reported to this dermatophyte species. [16][17] Also, we did not find any case of tinea pedis or tinea unguim during this study period. Tinea pedis is relatively uncommon in India and is the least prevalent of all the dermatomycoses.…”

Introduction: Dermatophytic infections are very common superficial fungal infections, which have been reported worldwide. Once considered to be easily treated may become recalcitrant and extensive. The three genera of dermatophytes involved for causing infection are Trichophyton, Epidermophyton and Microsporum. Some of the dermatophytes are cosmopolitan in distribution, while others can be geographically restricted. The epidemiology of dermatophytes may keep on changing due to migration, tourism, war, association with pets and also socioeconomic status. Material and methods: We conducted a study to find out the causative dermatophytes and clinical types associated with them. The clinical samples in the form of skin scrapings, plucked hair and nail scrapings and subungual debris were collected in the microbiology department of the tertiary care centre. The samples were subjected to 20% potassium hydroxide (KOH) mount and later inoculated on Sabouraud's Dextrose Agar (SDA) supplemented with chloramphenicol and cycloheximide. The plates were incubated at 25°C and observed for growth every week for four weeks. Results: We found that tinea corporis was the most common clinical type (61.20%) and was due to Trichophyton interdigitale (T. interdigitale) except one case, which was due to Trichophyton rubrum (T. rubrum). The next in frequency was tinea cruris (24.34%) due to T. interdigitale. Most of the cases of dermatophytosis were extensive without central clearing and with involvement of multiple anatomical sites. There was only one case of tinea capitis (0.65%) due to Trichophyton violaceum (T. violaceum). We did not find any inflammatory lesions or involvement of lymph nodes. Conclusion: To curb this epidemic like scenario of dermatophytosis in India will be a great challenge to the medical fraternity. Teamwork of dermatologist, mycologists, pharmacists, drug regulatory authorities, government and patients is essential.

Tinea capitis is of public health importance because of its transmissibility. Trichophyton violaceum and Trichophyton soudanense , which are common causes of tinea capitis in parts of Africa and West Asia, have only rarely been reported to cause dermatophytoses in the United States. We identified 24 patients with 25 positive cultures for T. violaceum or T. soudanense that were processed in a single hospital laboratory in Baltimore, Maryland, between 1 January 2000 and 30 June 2006. Most patients for whom clinical information was available had tinea capitis. There was a marked increase in the isolation of these organisms between the period from 2000 to 2002 and the period from 2003 to 2006, possibly associated with changes in immigration to the Baltimore metropolitan area. The changing epidemiology of this transmissible fungal infection not only is of public health interest as an example of the introduction of a “new” pathogen to an area where it traditionally was not endemic but also is of clinical and microbiological importance given reports suggesting an increasing incidence of tinea capitis in some areas and increasing clinical failure rates of current therapies.

A family outbreak of tinea capitis due to Trichophyton violaceum in Michigan. Its control with griseofulvin

Abstract: Trichophyton violaceum, BODIN, is a major cause of dermatophytic infection of the hair and skin in the Mediterranean region, eastern Europe, the Near East, and Asia (1,2,3). Its isolation is particularly frequent in the following countries: Portugal (4), Spain (5), south
