By means of UV radiation 74 physiological mutants of the dermatophyte Trichophyton mentagrophytes (Robin) Blanchard were induced. These mutants had changed optimum cultivation temperature and mostly changed morphology and sporulation as well.

This report describes the application of PCR fingerprinting for the identification of species and varieties of common dermatophytes and related fungi utilizing as a single primer the simple repetitive oligonucleotide (GACA)(4). The primer was able to amplify all the strains, producing species-specific profiles for Microsporum canis, Microsporum gypseum, Trichophyton rubrum, Trichophyton ajelloi...

The etiology and prevalence of Tinea Capitis in adults and children was studied in 115 cases. The most common etiologic agent was Trichophyton Violaceum recovered from 82 63% cases, Trichophyton rubrum from 10.4%, Trichophyton tonsurans from 3.47% and Microsporum canis from 3.4% cases. The study includes seventy cases of "blackdot" ringworm of the scalp, four cases of Kerion and forty one cases...

Tinea capitis (TC) is the dermatophytosis widespread in the world[1,2]. Not only specter of causative species in a specific geographical area is changing in time, but also the distribution of each one worldwide. No data exists on TC for recent 25 years in our country. Following goals were set for the study: to determine the specter of TC causatives and importance of age and sex in disease devel...

The fungistatic and fungicidal activities of sertaconazole against dermatophytes were evaluated by testing 150 clinical isolates of causative agents of tinea pedis, Trichophyton rubrum, Trichophyton mentagrophytes, and Epidermophyton floccosum. The overall geometric means for fungistatic and fungicidal activities of sertaconazole against these isolates were 0.26 and 2.26 μg/ml, respectively, al...

The Sensititre YeastOne antifungal panel was used to test 49 dermatophytes belonging to the species Epidermophyton floccosum, Microsporum gypseum, Microsporum canis, Trichophyton tonsurans, Trichophyton rubrum, and Trichophyton mentagrophytes. The MICs of four antifungals obtained with the Sensititre YeastOne antifungal panel were compared with those obtained by the reference NCCLS microdilutio...

2-Methyl-8-quinolinol and sixteen 5-, 7-, and 5,7-substituted derivatives with fluoro, chloro, bromo, iodo, nitro, and amino substituents were tested for in vitro antifungal activity against five fungi, Aspergillus niger, A. oryzae, Trichoderma viride, Myrothecium verrucaria, and Trichophyton mentagrophytes. The 5,7-dichloro and 5,7-dibromo derivatives were the most fungitoxic of the compounds ...

A n t i f u n g a l a c t i v i t y o f r h e i n ( 1 , 8 dihydroxyanthraquinone3carboxylic acid) isolated from the ethyl acetate extract of Cassia fistula flower was studied. Rhein inhibited the growth of many fungi such as Trichophyton mentagrophytes (MIC 31.25 μg/ml), Trichophyton simii (MIC 125 μg/ml), Trichophyton rubrum (MIC 62.5 μg/ml) and Epidermophyton floccosum (MIC 31.25 μg/ml).

conclusions species identification of trichophyton is crucially important for epidemiological and phylogenetic purposes and for genotype delineation. rca based on its polymorphisms can be used to generate identification barcodes and as an alternative to dna sequencing; it is a very fast, specific, and economical tool for species identification. results of the 61 putative trichophyton clinical i...
