Using internal transcribed spacer 1 (ITS1) region ribosomal DNA sequences from 37 stock strains and clinical isolates provisionally termed Trichophyton mentagrophytes complex in Japan, we demonstrated the mutual phylogenetic relationships of these strains. Members of this complex were classified into 3 ITS1-homologous groups and 13 ITS1-identical groups by their sequences. ITS1-homologous group...

Trichophyton mentagrophytes is a keratinophylic fungus belonging to a homogeneous group of fungi called the dermatophytes. The dermatophytes cause a variety of cutaneous infections in humans and animals. T. mentagrophytes has at least five different variants which make up the Trichophyton mentagrophytes complex. Two perfect states Arthroderma benhamiae and Arthroderma vanbreuseghemii have been ...

Background Dermatophytoses are common but poorly understood skin infections. Most in vivo studies have been performed using the guinea pig as the experimental animal model, which has several limitations. Objectives To develop a mouse model of dermatophytosis suitable for multiple purposes, including the investigation of immunity against dermatophytes. Methods Two peculiar fungal species, Arthro...

soil is well known to support the transient or ongoing existence of kerathophilic fungi and potential sources of infection for humans and animals. fifty soil samples were collected from various areas of forests and farmyards at golestan province in the north part of iran to determine the prevalence of keratinophilic fungi and dominant species. a total of 357 fungal colonies including 13 genera ...

This study was designed to determine the occurrence and species distribution of dermatophyte from cutaneous skin lesions of horses in Kaduna State, Nigeria. A total of 102 skin scrapings were collected from 102 horses with skin lesions. Mycological studies were carried out using conventional techniques. Dermatophytes were isolated from 18 (17.6%) of the 102 samples collected. The 18 dermatophyt...

Intra- and interspecies variations of the translation elongation factor 1-α (Tef-1α) gene were evaluated as a new identification marker in a wide range of dermatophytes, which included 167 strains of 30 species. An optimized pan-dermatophyte primer pair was designed, and the target was sequenced. Consensus sequences were used for multiple alignment and phylogenetic tree analysis and the levels ...

We report a case of an outbreak of inflammatory dermatophytoses caused by Arthroderma vanbreuseghemii (formally Trichophyton mentagrophytes pro parte) that involved an infected horse, the owner and at least 20 students, staff and stablemen at a veterinary school in Bern (Switzerland) that presented highly inflammatory dermatitis of the body and the face. Transmission from human to human was als...

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...
