2260 (1755 male and 505 female) preschool and school children of chabahar were studied for tinea capitis and pediculosis of the scalp. 42 cases were found positive in direct examination, 41cases endothrix being only one case; was ectothrix. trixhophyton violaceun was isolated from 40 cases and 4 of those were microscopically negative for fungal elements. totally, 46 cases of tinea capitis with ...

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...

OBJECTIVES Trichophyton violaceum is an anthropophilic dermatophyte that is endemic to parts of Africa and Asia and is sporadic in Europe. T. violaceum mainly causes tinea capitis in both children and adolescents. Although the infections caused by T. violaceum are of considerable medical importance, its antifungal susceptibility profile remains poorly examined. METHODS In this study, we teste...

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 ...

Strain PRAA4-1(T), a motile, Gram-negative, violet-pigmented bacterium, was isolated from Maryland forest soil and found to be orally toxic to Colorado potato beetle larvae and other insects. Morphological, biological, biochemical and molecular characterization revealed that this strain was most similar to Chromobacterium violaceum, the type species and only currently recognized member of the g...

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 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...

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...

tinea capities is the commonest dermatophytosis in children with diverse clinical presentations. the causative fungi of tinea capitis vary with geographic area and time.this study was aimed to identify the etiologic agents and determine the related factors of tinea capitis in tehran, iran. from clinically suspected cases of tinea capitis, microscopy and culture were performed. of 58patients 96%...
