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 ...

27 28 An oligonucleotide microarray, based on the arrayed primer extension (APEX) technique, has been 29 developed to simultaneously identify pathogenic fungi frequently isolated from invasive and 30 superficial infections. Species-specific oligonuceotide probes complementary to the internal 31 transcribed spacer (ITS1 and ITS2) region were designed for 24 species belonging to 10 genera, 32 inc...

Skin disease associated with keratinized tissues in animal and human beings has been investigated. The essential oil of Eucalyptus pauciflora in vitro showed strong antifungal activity at 1.0 microl/ml against human pathogenic fungi, viz. Epidermophyton floccosum, Microsporum audouinii, M. canis, M. gypseum, M. nanum, Trichophyton mentagrophytes, T. rubrum, T. tonsurans and T. violaceum. The oi...

Background. Wrestlers are at increased risk of developing cutaneous infections, including fungal infections caused by dermatophytes. Erythematous lesions due to tinea infections can be mistakenly diagnosed as an inflammatory dermatitis and incorrectly treated with potent topical corticosteroid treatments which cause localized skin immunosuppression. This can eventuate in a Majocchi granuloma wh...

The dermatophytes, keratinophilic fungi, represent important microorganisms of the soil microbiota, where there are cosmopolitan species and others with restricted geographic distribution. The aim of this study was to broaden the knowledge about the presence of dermatophytes in soils of urban (empty lots, schools, slums, squares, beaches and homes) and rural areas and about the evolution of the...
