Background: Dermatophytes create the most common fungal disease in humans, called dermatophytosis. The two species of Trichophyton rubrum and Trichophyton interdigital are responsible for over 80% of types of dermatophytosis. So far, several morphological and physiological methods have been used to differentiate these very similar species, but these methods are generally time-consuming and have...

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...

Restriction fragment length polymorphisms (RFLPs) identified in the ribosomal-DNA (rDNA) repeat were used for molecular strain differentiation of the dermatophyte fungus Trichophyton rubrum. The polymorphisms were detected by hybridization of EcoRI-digested T. rubrum genomic DNAs with a probe amplified from the small-subunit (18S) rDNA and adjacent internal transcribed spacer (ITS) regions. The...

Dermatophytes cause superficial and cutaneous fungal infections in immunocompetent hosts and invasive disease in immunocompromised hosts. However, the host mechanisms that regulate innate immune responses against these fungi are largely unknown. Here, we utilized commercially available epidermal tissues and primary keratinocytes to assess (i) damage induction by anthropophilic, geophilic, and z...

BACKGROUND In the absence of a functional dermatophyte-specific polymerase chain reaction (PCR), current diagnosis of dermatophytoses, which constitute the commonest communicable diseases worldwide, relies on microscopy and culture. This combination of techniques is time-consuming and notoriously low in sensitivity. OBJECTIVES Recent dermatophyte gene sequence records were used to design a re...

OBJECTIVE To evaluate the performance of the in-office dermatophyte test medium (DTM) culture when used to confirm the diagnosis of onychomycosis in diabetic patients. RESEARCH DESIGN AND METHODS Nail samples from 184 diabetic patients who exhibited symptoms consistent with toenail onychomycosis were screened for dermatophyte fungal infection using DTM, potassium hydroxide evaluation, and cen...

Fungal infections of hair, nail and skin are common worldwide and continue to increase. The present study was undertaken to determine the prevalence of dermatophytosis, isolation rates and the profile of fungi associated with dermatophytosis. Samples were collected from 305 patients and a portion of each sample was examined microscopically and the remaining portion was cultured on to plates of ...

background dermatophytes are a group of keratinophilic fungi worldwide, which can infect the skin, hair and nails of humans and animals. this genus includes several species that present different features of dermatophytosis. although, laboratory diagnosis of dermatophytes is based on direct microscopy, biochemical tests and culture, these manners are expensive, time consuming and need skilled s...
