MELANOID PIGMENT PRODUCTION IN A STRAIN OF TRICHOPHYTON RUBRUM

Melanoid pigment production in a strain of Trichophyton rubrum.

Trichophyton rubrutm is a dermatophyte that causes chronic and often serious superficial mycoses in man. Aside from descriptive, clinical, and biochemical studies, relatively little investigation has been done of the intermediary metabolism of the dermatophytes. Only recently have such studies been published (Jensen, Altschuller, and Bard, 1957; Burack and Knight, 1958). This study is concerned...

Differentiation of Trichophyton Rubrum and Trichophyton Mentagrophytes by Pigment Production.

Clinical Trichophyton rubrum strain exhibiting primary resistance to terbinafine.

The in vitro antifungal susceptibilities of six clinical Trichophyton rubrum isolates obtained sequentially from a single onychomycosis patient who failed oral terbinafine therapy (250 mg/day for 24 weeks) were determined by broth microdilution and macrodilution methodologies. Strain relatedness was examined by random amplified polymorphic DNA (RAPD) analyses. Data obtained from both broth micr...

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 ...

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...
