Interactions of Trichophyton mentagrophytes and Micrococci on Skin Culture

Dermatophyte isolation media: quantitative appraisal using skin scales infected with Trichophyton mentagrophytes and Trichophyton rubrum.

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....

Differentiation of Trichophyton Rubrum and Trichophyton Mentagrophytes by Pigment Production.

Glycolytic and respiratory enzymes of Trichophyton mentagrophytes.

Although the dermatophytes are common fungal pathogens, very little is known concerning their metabolic systems. Biochemical studies with this group have been limited primarily to the nutritional requirements (Robbins et al., 1942; Schopfer and Blumer, 1943; Robbins and Ma, 1945; Georg, 1950; Benham, 1953; Silva, 1953; and Silva and Benham, 1954) and the demonstration of various extracellular e...

Trichophyton mentagrophytes a keratinophilic fungus

Trichophyton mentagrophytes is a keratinophylic fungus belonging to a homogeneous group of fungi called the dermatophytes. The dermatophytes cause a variety of cutaneous infections in humans and animals. T. mentagrophytes has at least five different variants which make up the Trichophyton mentagrophytes complex. Two perfect states Arthroderma benhamiae and Arthroderma vanbreuseghemii have been ...

Survival and resistance of Trichophyton mentagrophytes arthrospores.

The effects of several physical and chemical agents on the survival of Trichophyton mentagrophytes arthrospores were investigated. Although arthrospores of this dermatophyte were highly resistant to chilling and freezing, they were extremely susceptible to moderate heat (above 50 degrees C) and desiccation. This high susceptibility could be significantly reduced when they were dried in the pres...
