Molecular taxonomy of the Trichophyton rubrum complex.
The validity of taxa around Trichophyton rubrum was evaluated by a combination of phenetic and molecular methods. Morphological and physiological features were compared to results of sequencing of the internal transcribed spacer region of the ribosomal operon, PCR fingerprinting, and amplified fragment length polymorphism analysis. The 15 species and varieties investigated (Trichophyton circonv...
متن کاملElectrophoretic molecular karyotype of the dermatophyte Trichophyton rubrum
The electrophoretic karyotype of the dermatophyte Trichophyton rubrum was established using contour-clamped homogeneous electric field (CHEF) gel electrophoresis. Five chromosomal bands of approximately 3.0 to 5.8 megabase pairs (Mbp) each were observed and together indicated that 22.05 Mbp of the total genome are organized as chromosomal macromolecules. In addition to establishing the number a...
متن کاملDiagnostic value of morphological, physiological and biochemical tests in distinguishing Trichophyton rubrum from Trichophyton mentagrophytes complex.
The two most frequently encountered dermatophyte etiologic agents of glabrous skin and nail dermatophytoses are Trichophyton rubrum and T. mentagrophytes. This study was aimed to discuss the efficacy of morphological, physiological and biochemical diagnostic tests commonly used in the identification of T. rubrum and members of the T. mentagrophytes complex. In this study, we evaluated; hydrolys...
متن کاملTrichophyton rubrum infection of the prepuce.
Sir, Dermatophyte infection of the penis and scrotum is rare. It is difficult to explain why the penile shaft is generally not involved in patients affected by tinea cruris. Glans penis involvement is considered even rarer, whereas dermatophytosis of the prepuce has not been reported in the literature. Here we report a patient who presented with scaly lesion on the prepuce, which on investigati...
متن کاملFactors affecting the antigenicity of Trichophyton rubrum.
Nitrogen determinations, performed upon the mycelia of Trichophyton rubrum, indicated that both the total nitrogen to mycelial weight ratio and the protein nitrogen to mycelial weight ratio decreased as the age of the mycelia increased. An increase in nitrogen concentration in the medium produced an increase in the total nitrogen to mycelia weight ratio, but did not necessarily increase the pro...
