Carotenogenesis associated with arthrosporulation of Trichophyton mentagrophytes

Carotenogenesis associated with arthrosporulation of Trichophyton mentagrophytes.

Carotenoid pigments were demonstrated in arthrospores of the dermatophyte Trichophyton mentagrophytes but were absent from hyphae and microconidia of this fungus. Incubation at higher temperatures (39 degrees C) allowed arthrosporulation to occur, but essentially no carotenoid was detected in such arthrospores. The carotenoid formation in arthrosporulating T. mentagrophytes did not appear to be...

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 ...

Differentiation of Trichophyton Rubrum and Trichophyton Mentagrophytes by Pigment Production.

Rosacea-like tinea incognito due to Trichophyton mentagrophytes vr. mentagrophytes.

Tinea incognito is a dermatophytosis with atypi-cal clinical manifestation in the absence of the typical " ringworm " (1). The term tinea incognito was originally used in 1968 by Ive and Marks in 14 patients with atypical dermatophytic infection caused by a previous steroid treatment (2). Since then, several cases of tinea incognito have been described after topical application of pimecrolimus ...

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...
