Relationship between Candida albicans producing proteinase (CAPP) and its environmental pH--comparison with a case of trichophyton mentagrophytes.
Candida albicans produced a karatinolytic proteinase (KPase) or C. albicans producing proteinase (CAPP), a proposed new term for this enzyme, and Trichophyton mentagrophytes also produced KPase when cultivated in liquid medium containing human stratum corneum (HSC) as the nitrogen source, but were unable to do so when cultivated in sabouraud dextrose broth. Purified KPase from the culture super...
متن کاملIsolation and purification of an extracellular keratinase of Trichophyton mentagrophytes.
The keratinolytic activities of dermatophytes which parasitize skin, nails, and hair have been described previously (1, 3, 6, 8); however, the isolation of a keratinase from these organisms has not yet been reported. Trichophyton mentagrophytes var. granulosum (T. granulosum Sabouraud, 1909) was grown in a keratin medium composed of (per liter): horse hair, 2.5 g; glucose, 0.9 g; MgSO4.7H20, 0....
متن کاملDermatophyte 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....
متن کاملTrichophyton 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 ...
متن کاملCarotenogenesis 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...
