Tinea pedis (athlete’s foot) is a common fungal infection of the feet with the major causative organisms being Trichophyton rubrum, Trichophyton mentagrophytes and Epidermophyton floccosum1. It occurs worldwide, with a greater frequency and severity during the warmer months of the year.

Dermatophytes are agents of typically benign superficial infections. However, an increasing number of severe infections in immunocompromised hosts has been reported. We aimed to understand the factors underlying the existence of a cohort of patients presenting with chronic widespread dermatophytosis (CWD) due to Trichophyton rubrum, but with no signs of immunodeficiency. Their disease is usuall...

The individual colonies of a partially degenerated culture of Aspergillus versicolor vary widely in their ability to produce an antibiotic active against Trichophyton rubrum. Mutagenic treatment with nitrous acid or ultraviolet light gave potent colonies. Nitrous acid gave better results in terms of stability and yield. This treatment may therefore prove useful in the regeneration of partially ...

BACKGROUND Modifications in social habits together with the increase of emigration have contributed not only to increased dermatophytoses but also to an altered etiology. During the last few years, Braga has suffered a radical change from a rural to a cosmopolitan life-style. METHODS A statistical study of dermatophytoses and the etiology of their causative agents was performed by a retrospec...

BACKGROUND Few scientific studies have evaluated dermatophytosis among children in the state of Amazonas or in the greater northern region of Brazil. AIMS The aim of this study was to research the frequency and aetiology of dermatophytosis in children age 12 and under, who were seen between March 1996 and November 2005 at the Mycology Laboratory of the National Institute of Amazonian Research...
