Trichophyton rubrum and Trichophyton mentagrophytes complex, or Trichophyton spp. are the main etiologic agents of dermatophytosis, whose treatment is limited by the high cost of antifungal treatments, their various side effects, and the emergence of resistance amongst these species. This study evaluated the in vitro antidermatophytic activity of 23 crude extracts from nine plant species of sem...

Investigations were carried out to evaluate the therapeutic properties of the seeds and leaves of Moringa oleifera Lam as herbal medicines. Ethanol extracts showed anti-fungal activities in vitro against dermatophytes such as Trichophyton rubrum, Trichophyton mentagrophytes, Epidermophyton floccosum, and Microsporum canis. GC-MS analysis of the chemical composition of the essential oil from lea...

Dear Editor, Tinea barbae is a dermatophyte infection that affects primarily the bearded areas of the face.1 Sycosis is one type of clinical manifestation associated with deep folliculitis. The infection is usually caused by zoophilic fungi acquired after contact with animals.2 The presence of anthropophilic fungi, such as Trichophyton rubrum (T. rubrum), has recently been reported, and they of...

During the period January 1999 to July 2002 a total de 164 cases of Tinea capitis were diagnosed by mycological examination in Instituto de Patologia Tropical e Saúde Pública of the Universidade Federal de Goiás. Of the 164 patients 94 (57.3%) were males, with an age of 3 months to 13 years. Laboratory studies were performed by direct examination with 20% KOH and cultivated on Mycobiotic agar m...

Prevalence of dermatophytosis, with respect to age and sex and dermatophyte species, in Jaen was investigated during a period of three years (1996-1999). The prevalence of dermatophytosis over three years was 4.48 cases / 1000 inhabitants. The isolated species were: Microsporum canis (48.6%), Trichophyton mentagrophytes (27.1%), Epidermophyton floccosum (10%), Trichophyton rubrum (8.6%), Tricho...

The present study was undertaken to find the predominant etiological agent of dermatophytoses among the patients attending the out patient clinic of Mycology Section, Department of Dermatology, Madras Medical College and Hospital, Chennai. Specimens were collected from suspected patients with dermatophytoses and examined for the presence of fungal elements, cultured, isolated and identified. Am...

INTRODUCTION Dermatophytoses are considered a public health problem. The objectives of this study were to determine the evolution of their prevalence in the metropolitan area of Porto Alegre, Brazil, and to analyze the dermatophyte species distribution according to body site and demographic characteristics of the patients. METHODOLOGY This work was a retrospective analysis of data from patien...

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...

Various dermatophyte isolation media were quantitatively appraised by colony counts for their ability to support growth when suspensions of trypsin-treated infected-skin scales were used as inocula. Evaluation included guinea pig skin scales infected with a granular Trichophyton mentagrophyton mentagrophytes, and one trial was conducted using human skin scales infected with Trichophyton rubrum....
