Trichophyton rubrum is the main agent causing dermatophytosis (1). Keratinocytes are considered to be the first physical barrier of defense against pathogens (2). But not only a physical barrier. They recognize antigens through Toll like receptors (TLR) (3). The activation of this TLR, present on the surface of the keratinocytes, induce the expression of different pro-inflammatory cytokines, co...
Around 90% of chronic dermatophyte infections are caused by the fungi Trichophyton mentagrophytes and Trichophyton rubrum. One of the causes of the chronic infection resides in the immunosuppressive effects of the cell-wall components of these organisms. Therefore we have attempted to identify the chemical structure of galactomannan, one of the major cell-wall components. The cell-wall polysacc...
Trichophyton rubrum is one of the major causative agents of dermatophytosis in humans worldwide. We report the draft genome sequence of T. rubrum var. raubitschekii from Delhi, India, isolated from a patient presenting symptoms of onychomycosis. The total estimated genome size of the clinical isolate is 25.2 MB containing 8265 predicted protein-coding sequences, 91 tRNA and 15 rRNA genes. Seque...
Application of molecular typing methods to dermatophyte species that cause skin and nail infections.
Typing methods utilising DNA technology were applied to a collection of Trichophyton mentagrophytes and T. rubrum isolates from skin and nail infections. The methods included restriction enzyme analysis (REA), hybridisation with the DNA probe poly (dG-dT), randomly amplified polymorphic DNA (RAPD) by PCR and restriction analysis of a segment of PCR-amplified rDNA. All these tests successfully d...
This study shows the effectiveness of photodynamic therapy based on methylene blue dye for the treatment of endonyx toenail onychomycosis. Four patients with endonyx onychomycosis caused by Trichophyton rubrum were treated with 2% methylene blue aqueous solution irradiated with light emission diode at 630 nm and an energy density of 36 J/cm2 for 6 months at 2-week intervals. The preliminary stu...
Fagara zanthoxyloides was screened for biologically active ingredients and its antifungal activities. The results revealed that the plant extract possessed the following active ingredients: alkaloids, saponins, tannins and glycosides. The extract exerted inhibitory effect on Microsporum canis, Trichophyton rubrum and Trichophyton mentagrophytes. The minimum inhibitory concentration of the extra...
The Saccharomyces cerevisiae killer toxin KT 28, which inhibits sensitive yeasts, was shown to have no effect on several pathogenic fungi or on the protozoan Trichomonas vaginalis. At concentrations of about 0.1 mg/ml, a partial inhibition of the skin pathogenic fungi Trichophyton rubrum and Microsporum canis was observed at pH 6.5. No pharmacological activity was detected in various tests with...
