1. Tinea capitis: dermoscopy and calcium fluorescent microscopy as highly efficient and precise diagnostic tools
Abstract Tinea capitis comprising of tinea favosa and kerion is mostly seen in school-aged children. Some tinea capitis often presented with insignificant findings under the naked eyes are easily overlooked. The authors describe an unusual case of tinea capitis caused by Trichophyton violaceum. The patient was an 8-year-old girl, with a history of pruritus o

2. Frequency of dermatophytes in the metropolitan area of Porto Alegre, RS, Brasil
In order to evaluate the distribution of dermatophytes in Porto Alegre, the capital of the state of Rio Grande do Sul, Brazil, they were isolated from the skin, hairs and nails samples and retrospectively analyzed from June 1981 to June 1995, in two different institutions in the city of Porto Alegre: (i) the Serviço de Micologia do Instituto de Pesquisas Bi

3. Tinea capitis em adulto por Trichophyton violaceum no Brasil: relato de um caso e revisão da literatura
Tinea capitis, tinha do couro cabeludo, é dermatofitose causada por fungos dos gêneros Trichophyton e Microsporum. Apresenta várias formas clínicas e é quase exclusiva de crianças. Raramente acomete adulto. Relata-se um caso de tinea capitis por T. violaceum em mulher com 65 anos de idade e comentam-se os aspectos nosográficos dessa dermatofitose no B

4. Tinea capitis entre as crianças de uma escola primária suburbana na Cidade Maputo, Mozambique
O estudo avaliou a prevalência da Tinea capitis na população estudantil duma Escola Primária e também identificou os agentes causais responsáveis. Escamas do couro cabeludo foram recolhidas das crianças apresentando sinais clínicos sugestivos de Tinea capitis. Dermatófitos foram identificados seguindo procedimentos micológicos padronizados. Este es

5. Molecular Taxonomy of the Trichophyton rubrum Complex
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 varieti

6. Origins of Microsatellite Diversity in the Trichophyton rubrum- T. violaceum Clade (Dermatophytes)
We analyzed the population structure of the anthropophilic dermatophyte species Trichophyton violaceum, which mainly causes tinea capitis, and T. rubrum, the most frequently isolated agent of dermatophytosis worldwide. A microsatellite marker (T1) was developed by using the enrichment technique for microsatellites. The T1 marker containing a (GT)8-10 repeat

7. Phylogenetic Classification and Species Identification of Dermatophyte Strains Based on DNA Sequences of Nuclear Ribosomal Internal Transcribed Spacer 1 Regions
The mutual phylogenetic relationships of dermatophytes of the genera Trichophyton, Microsporum, and Epidermophyton were demonstrated by using internal transcribed spacer 1 (ITS1) region ribosomal DNA sequences. Trichophyton spp. and Microsporum spp. form a cluster in the phylogenetic tree with Epidermophyton floccosum as an outgroup, and within this cluster,

8. Strain Identification of Trichophyton rubrum by Specific Amplification of Subrepeat Elements in the Ribosomal DNA Nontranscribed Spacer
Trichophyton rubrum is the commonest cause of dermatophytosis of skin and nail tissue. Molecular characterization of the T. rubrum ribosomal DNA nontranscribed-spacer region revealed two novel tandemly repetitive subelements (TRSs): TRS-1, containing a 27-bp palindromic sequence, and TRS-2. Specific amplification of TRS-1 produced strain-characteristic bandi

9. Initiation of Dermatophyte Pleomorphic Strain Sporulation by Increased Aeration
A normally asporogenous pleomorphic strain of Microsporum gypseum was induced to sporulate by controlled aeration and dehydration. Aeration of the pleomorphic strain under optimal cultivation conditions caused the initiation of a sporulation cycle with equivalent growth parameters and percentage intracellular water loss as the wild-type strain. Initiation of
