conclusions species identification of trichophyton is crucially important for epidemiological and phylogenetic purposes and for genotype delineation. rca based on its polymorphisms can be used to generate identification barcodes and as an alternative to dna sequencing; it is a very fast, specific, and economical tool for species identification. results of the 61 putative trichophyton clinical i...

BACKGROUND AND OBJECTIVES Cutaneous fungal infections are a major public health problem. The distribution of the dermatophytoses varies between countries and geographical areas. The aim of this study was to determine the incidence, epidemiology, etiology, and clinical course of the dermatophytoses caused by anthropophilic fungi in Cadiz, Spain, over the past 12 years. MATERIAL AND METHODS The...

DNA sequencing analyses have demonstrated relatively limited polymorphisms within the fungal internal transcribed spacer (ITS) regions among Trichophyton spp. We sequenced the ITS region (ITS1, 5.8S, and ITS2) for 42 dermatophytes belonging to seven species (Trichophyton rubrum, T. mentagrophytes, T. soudanense, T. tonsurans, Epidermophyton floccosum, Microsporum canis, and M. gypseum) and deve...

Bromocresol purple-milk solids-glucose medium, proposed by Fischer and Kane in 1971 (Mycopathol. Mycol. Appl. 43:169-180, 1971) as an aid in the rapid determination of Trichophyton rubrum and Trichophyton mentagrophytes, was evaluated across a wide range of isolates to determine its accuracy and efficacy in the clinical laboratory. Results showed that it facilitated accurate determination of ty...

Multi-target strategies are directed toward targets that are unrelated (or distantly related) and can create opportunities to address different pathologies. The antidermatophytic activities of nine natural skin lighteners: α-bisabolol, kojic acid, β-arbutin, azelaic acid, hydroquinone, nicotinamide, glycine, glutathione and ascorbyl tetraisopalmitate, were evaluated, in comparison with the know...

since most of the studies on chemical compounds of dermatophytes have shown the existence of a relationship between their pathogenisity and proteolytec enzymes. activities of 19 different enzymes in viable mycelia and cytoplasmic extracts of t.rubrum (cetr), t.mentagrophytes (cetm) and t.verrucosum (cetv) were investigated by the api-zym system. the results showed that viable mycelia of t.rubrm...

During the period January 1999 to July 2002 a total de 164 cases of Tinea capitis were diagnosed by mycological examination in Instituto de Patologia Tropical e Saúde Pública of the Universidade Federal de Goiás. Of the 164 patients 94 (57.3%) were males, with an age of 3 months to 13 years. Laboratory studies were performed by direct examination with 20% KOH and cultivated on Mycobiotic agar m...
