background and objectives: dermatophytes possess a wide array of virulence factors and various antifungal susceptibility patterns which influence their pathogenesis in humans and animals. the aim of this study was to evaluate antifungal suscep- tibility and keratinase and proteinase activity of 49 dermatophyte strains from the genera microsporum , trichophyton and epidermophyton which were isol...

INTRODUCTION Dermatophytes are a closely related group of keratinophilic fungi. They encompass important etiological agents of superficial fungal infections. These fungi are able to invade keratinized tissues of humans and animals, causing dermatophytosis (ringworm) of hair, nails or skin. THE AIM Traditional diagnostics of ringworm is based on morphological identification of cultured fungi a...

BACKGROUND Tinea pedis and tinea manuum in children are more common than previously recognized. Clinical presentations of dermatophyte infections may vary in children and may be difficult to diagnose. OBJECTIVE To show the necessity of potassium hydroxide preparations and/or fungal cultures in assessing suspicious cases of cellulitis in children who may have dermatophyte infections. PATIENT...

subungual onychomycosis, which is the typical appearance seen in most dermatophyte infections: the disease spreads from the hyponychium into the nail and then progresses proximally, frequently along the lateral margins to affect the whole nail. Superficial white onychomycosis can be caused by a dermatophyte, usually Trichophyton mentagrophytes var. interdigitale or by nondermatophytic moulds. T...

onychomycosis is the fungal infection of the nails with worldwide occurrence, caused by various species of dermatophytes, yeasts and molds. in addition, of pain and physical effect of onychomycosis that may interfere with individual’s personal and professional life, it may also causes negative psychosocial consequences in patients. concerning increase of onychomycosis during recent decades and ...

We studied dermatophyte infections in patients attending the Dermatology Outpatients Clinic of S. Matteo hospital Pavia, Italy, during the period 2004-2006. A total of 100 samples were collected from 95 patients; 97 dermatophytes and 3 keratinophylic fungi were isolated. Trichophyton rubrum was the most frequent dermatophyte isolated (42.3%), followed by Microsporum canis (31%), T. mentagrophyt...

Sir, The frequent dermatophyte infections of swimmer’s feet are most likely related to increased exposure to dermatophytes and maceration of skin (1). Fungal particles are shed from infected tissues and found on the floors of shared bathing facilities (2–5). Two studies have revealed a higher level of contamination in men’s dressing rooms than in women’s (2, 4), and a higher rate of tinea pedis...

Various dermatophyte isolation media were quantitatively appraised by colony counts for their ability to support growth when suspensions of trypsin-treated infected-skin scales were used as inocula. Evaluation included guinea pig skin scales infected with a granular Trichophyton mentagrophyton mentagrophytes, and one trial was conducted using human skin scales infected with Trichophyton rubrum....

Use of phylogenetic species concepts based on rDNA internal transcribe spacer (ITS) regions have improved the taxonomy of dermatophyte species; however, confirmation and refinement using other genes are needed. Since the calmodulin gene has not been systematically used in dermatophyte taxonomy, we evaluated its intra- and interspecies sequence variation as well as its application in identificat...
