Trichophyton rubrum como principal agente etiológico de dermatofitoses em um laboratório de Maceió –Al / Trichophyton rubrum as the main ethological agent of dermatophytoses in a Maceió-Al laboratory

Differentiation of Trichophyton Rubrum and Trichophyton Mentagrophytes by Pigment Production.

Trichophyton 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...

Factors 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...

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...

Trichophyton rubrum: The Commonest Isolate from Dermatophytosis

Dermatophytosis is a trivial disease but has lot of psychological effect and a costly disease in terms of treatment. Though various species of dermatophytes produce clinically characteristic lesions, but a single species may produce variety of lesions depending upon site of infection. The present study was undertaken with following aim and objectives. Isolation and identification of different e...
