Differentiation of Trichophyton rubrum and Trichophyton mentagrophytes by Pigment Production1

Differentiation of Trichophyton Rubrum and Trichophyton Mentagrophytes by Pigment Production.

Rapid method for differentiation of Trichophyton rubrum, Trichophyton mentagrophytes, and related dermatophyte species.

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...

enzyme activities in trichophyton rubrum, trichophyton mentagrophytes and trichophyton verrucosum

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...

Extracellular Production of Silver Nanoparticles by Using Three Common Species of Dermatophytes: Trichophyton rubrum, Trichophyton mentagrophytes and Microsporum canis

Background: To develop a new green approach for biosynthesis of silver nanoparticles, myconanotechnology has been represented as a novel field of study in nanotechnology. In this study, we have reported the extracellular synthesis of highly stable silver nanoparticles using three species of dermatophytes: Trichophyton rubrum, Trichophyton mentagrophytes and Microsporum canis. Methods: Clinical ...

NMR study of the galactomannans of Trichophyton mentagrophytes and Trichophyton rubrum.

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...
