The validity of taxa around Trichophyton rubrum was evaluated by a combination of phenetic and molecular methods. Morphological and physiological features were compared to results of sequencing of the internal transcribed spacer region of the ribosomal operon, PCR fingerprinting, and amplified fragment length polymorphism analysis. The 15 species and varieties investigated (Trichophyton circonv...

Antifungal activity of naftifinc (SN 105-843 gel) a napthyle alkyleamine derivative, was measured in vitro against freshly isolated cultures of dermatophytie fungi. Using appropriate concentrations of naftifine, its antifungal activity was compared with the same concentrations of griseofulvin against Trichophyton rubrum, Trichophyton mentagrophytes, Trichophyton violaceum, Trichophyton tonsuran...

from 687 patients referred to the medical mycology depatment of the school of public health, 184 cases showed tinea capitis infection, direct microscopy and culture was positive in 86.2% and 75.29% of the cases respectively. from the positive cultures 5 different dermatophtes were identified as: microsporum canis, trichophyton violaceum, trichophyton verrucosum, trichophyton schoenleinii, trich...

Dermatophytes are Fungi which infect keratinized tissues, that is, skin epidermis, hair and nails. Trichophyton violaceum is an anthropophilic, cosmopolitan dermatophyte. It primarily causes tinea capitis and less commonly tinea corporis and tinea unguium. We present a report of two cases of tinea corporis due to T. violaceum in children. Infections due to T. violaceum are important because of ...

The intergenic spacer (IGS) of the rRNA genes was analyzed from the dermatophyte Trichophyton violaceum isolated from cases of tinea capitis in Taiwan and Iran. T. violaceum strains were cultured from different colonies, from single conidial colonies derived by dilution plating, and from micromanipulation of single conidia from clinical samples. A ribosomal DNA probe hybridizing to multiple Eco...

Trichophyton violaceum is an uncommon cause of tinea pedis. We report a case of bullous tinea pedis caused T. violaceum in a 7-year old otherwise healthy child living in the United States. She achieved clinical recovery with a 1month course of oral terbinafine.

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...

The aqueous extracts (15 micrograms ml-1 medium) of 22 plants used in folkloric medicine in Palestine were investigated for their antifungal activity and minimum inhibitory concentrations (MICs) against nine isolates of Microsporum canis, Trichophyton mentagrophytes and Trichophyton violaceum. The extract of the different plant species reduced colony growth of the three dermatophytes by 36 to 1...

One strain of Trichophyton rubrum CMCC(F)T1i (=CBS 139224) isolated from onychomycosis and one strain of Trichophyton violaceum CMCC(F)T3l (=CBS 141829) isolated from tinea capitis in China were whole-genome sequenced by Illumina/Solexa, while the former was also sequenced by Pacific Biosciences sequencing in parallel.
