Background and Purpose: Globally, dermatophytes are the most common filamentous group of fungi causing cutaneous mycoses. Dermatophytes were shown to secrete a multitude of enzymes that play a role in their pathogenesis. There is limited data on co-hemolytic (CAMP-like) effect of different bacterial species on dermatophyte species. In this study, we sought to the evaluate exoenzyme activity an...

structures with typical arrangement on hyphae, chlamydospores, spirals, antler-shaped hyphae (chandeliers), nodular organs, pectinate organs and racquet hyphae [2,4]. In addition, some physiological characteristics based on nutritional requirements [4-8]such as vitamin deficiency can be used to identify some dermatophytes. Most dermatophyte colonies develop forms and pigmentation which can allo...

Dermatophytes are pathogenic fungi that infect human skin, nails and hair and cause dermatophytosis. Trichophyton mentagrophytes is one of the most widespread species that belong to this group. Infection of the skin tissues include several stages, i.e., adhesion to the surface of the skin, invasion into the sublayers by the penetration of fungal elements and secretion of enzymes that degrade th...

Tinea capitis caused by Trichophyton tonsurans has been increasing in the United States for the past 25 years. A retrospective study of dermatophyte culture data at the University of California, San Francisco, and a parallel study of patient visits for tinea capitis at an affiliated hospital demonstrates a dramatic rise in Trichophyton tonsurans tinea capitis in the San Francisco Bay area.

Report of a case of tinea corporis caused by Microsporum gypseum in a 36-year-old female Aids patient. The literature does not refer this dermatophyte as a common etiologic agent in this group of patients.The lesions were generalized,psoriasiform and refractory to treatment with ketoconazole and itraconazole.
