Tinea capitis caused by Trichophyton tonsurans has been increasing in the United States for the past 25 years. A retrospective study of dermatophyte culture data at the University of California, San Francisco, and a parallel study of patient visits for tinea capitis at an affiliated hospital demonstrates a dramatic rise in Trichophyton tonsurans tinea capitis in the San Francisco Bay area.

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...

BACKGROUND Tinea capitis affects mainly children. The frequency and causative organism vary from region to region. OBJECTIVES To provide epidemiological and mycological data on tinea capitis collected in urban and rural areas of the Dominican Republic. METHODS Samples were obtained from 118 patients with tinea capitis. Sixty-three of these were from 2 schools in urban areas of the Dominican...

Onychomycosis is predominantly caused by the dermatophytes Trichophyton rubrum, Trichophyton mentagrophytes and Trichophyton tonsurans. The main treatment obstacle concerns low nail-plate drug permeability. In vitro antifungal photodynamic treatment (PDT) and nail penetration enhancing effectiveness have been proven for multifunctional photosensitizer 5,10,15-tris(4-N-methylpyridinium)-20-(4-(b...

We report here the first case of neonatal tinea faciei caused by Trichophyton tonsurans in mainland China. The mother of the infant had tinea corpris and tinea capitis while the father had tinea incongnito. The infections in the parents were mycologically confirmed to be due to Trichophyton tonsurans. Ttinea faciei in the infant was cured after two-week topical use of amorolfine cream. The moth...

BACKGROUND The high degree of phenotypic similarity among Trichophyton species makes their identification difficult. OBJECTIVES The current study aims to establish the use of rolling circle amplification (RCA) based on internal transcribed spacer ribosomal DNA (ITS rDNA) as a powerful, simple, and rapid procedure for distinguishing closely related organisms, and specifically to identify Trich...

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...

Chloroform, Methanol and Water extract of Solanum indicum Linn., a widely used food and medicinal plant of Assam, India was investigated for its in vitro antifungal activity against five different dermatophytic fungi viz., Trichophyton mentagrophytes, Trichophyton rubrum, Trichophyton tonsurans, Microsporum gypseum and Microsporum fulvum. Agar well diffusion method was used to determine the inh...
